Pleasure Cruise

The jangling of my phone interrupted the steady beat of my hand on my cock as I picked it up and answered the call, simultaneously pressing pause on the porn video running on my TV, the moment of penetration of an improbably large cock into a shaven pussy frozen on the screen. A little annoyed at the interruption by what was probably a sales call from abroad I answered, "Hello?"

"You don't sound happy, have I interrupted anything important?" came my sister's voice from the speaker.

"No, nothing I can't get back to later," I replied, my hand returning to my cock to resume my stroking although not with quite the same vigour. "How are you?" We didn't see as much of each other as either of us would have wished, it wasn't that we lived too far apart, or that either of us were too busy, it was just inertia, the knowledge that either of us would drop everything in a trice should the need arise to help out with something, meaning that we didn't need to live in each other's pockets.

We were both divorced, in our forties and comfortably well off in good jobs, in my case as a self-employed consultant. It suited me being able to pick and choose my work to a certain extent, I had enough opportunities to earn a lot more, but I wanted to be able to enjoy my work, not to be a slave to it.

We chatted about inconsequentialities for a while, caught up on each other's children, or rather grown-up offspring, before Jenny finally got round to the purpose of the call. "Are you free during the second week of July?" I checked my diary and confirmed that I could be with a little manoeuvring, "Only I wondered if you'd like to come on a Mediterranean cruise with me?" That had to be the thing the furthest from my thoughts when it came to the purpose of the call and for a moment I found myself completely speechless. "From your silence I guess the answer is no."

"No, absolutely not." Then it hit me that my answer could be taken completely the wrong way, "No, I mean yes. Oh shit, you know what I mean."

"But I don't David." I heard laughter down the phone, "It would be completely free, all paid for by my delightful employers, I seem to have been awarded Employee of the Year and the prize is a week's cruise for two, only I haven't actually got anyone to go with."

"Surely you must have someone better than me, some boyfriend or lover who'd keep you nice and warm at night."

"Sadly no, those who would be acceptable are already married or partnered up, and those who aren't would definitely not be acceptable. So I've scraped the bottom of the barrel and have come up with you! So will you come and keep a lonely old maid happy?"

"Well if you put it like that, as an act of charity, then I could possibly manage." A thought suddenly occurred to me, "Would we have to share a cabin?"

There was silence for a second or two. "Would that cause a problem? We used to share a room one upon a time."

"Yes Jen, when we were ten, then you started growing bumps on your chest and our parents separated us. But no it wouldn't worry me if you're happy with it, I'm sure there'll be plenty of room for us to have our own space."

"Then you'll come?"

"I'll be delighted!"

The rest of the call settled a few outstanding details and then we hung up and I resumed the video, but my mind kept wandering to the thought of sharing a cabin with my sister for a week, and when I came it was not the porn actors that my mind saw, but an imagined version of my sister, naked and spread across a sumptuous bed.

We met up a couple of times in the months prior to departure, each time my sister asking if I'd changed my mind. Surprisingly I actually found myself looking forward to it more and more. I'd never been on a cruise, my ex-wife got sea-sick looking at a picture of a boat so we'd never been, but I quite liked the idea of waking up in a different port each morning and by the time we were sitting on the plane at Gatwick waiting for take-off, I was positively itching to get on with it.

Of course the faff of actually getting on the boat was almost enough to put me off for life, first the airport immigration formalities, then the coach ride, then the port formalities and registration, but finally we opened the door onto our cabin. I don't know who said, "Oh!" first, both of us registering with some dismay the size, or rather lack of size of the cabin. The photographs had clearly been taken with the same camera that took photos of the interior of houses for sale, and the wide open spaces were in fact narrow gaps between items of furniture.

On the plus side it was all very neat and clean and well appointed, just small, and the bathroom was more of a cupboard. "Well it was free," I put a brave face on it, "and we'll be outside for most of the time, or asleep." That was the other thing, some of the pictures had shown twin beds, but clearly there was only one in the cabin, and not exactly double king sized at that.

"Just as well I brought some pyjamas," said Jenny, looking at the bed.

"Erm..." I replied, then seeing the look on her face, added, "Course I did!" I had in fact been out and bought some specifically, as I didn't normally wear anything to bed at all. "We can get changed in the bathroom, and if we need a bit of space there's always the balcony." We did in fact have a balcony with two plastic chairs squeezed on it, so at least we had a sea view rather than an inside cabin.

We unpacked and found room for the empty cases under the bed which did at least give us a bit more space. It was getting on for dinner time and for the first night there was no formal dinner sitting, the ship operated a flexible policy, you could either book for a formal setting, or opt for a more casual buffet style, something that suited both of us. "I'll go and have a shower," said Jenny, "all that travelling makes me feel so grimy." She headed for the bathroom and closed the door while I settled onto the bed and picked up the cruise ship brochure and guide and began leafing through it.

It was pretty comprehensive and I was trying to absorb all the information and barely registered the noises coming from the bathroom until the door opened and a flustered looking Jenny stepped out, a towel wrapped tightly round her body. "You can't swing a dead cat in there, we'll have to dress out here or everything will get wet." I looked up at her wondering if she was indeed naked under the towel.

"You didn't tell me this was an Adults Only cruise," I commented.

"Why? You wouldn't want a load of screaming kids everywhere would you?"

"No, not particularly, but when I said 'Adults Only' I meant 'Adults Only'!" Jenny looked confused, "Let me quote, 'topless sunbathing is permitted at all pools, but full nudity is only allowed in the pool on the aftermost deck.' and 'Activities of a sexual nature are only allowed in designated areas, clearly marked as such'."

"There must be some mistake," said Jenny, grabbing the brochure from me, and nearly letting go of her towel in the process. She read the paragraphs carefully before handing me back the brochure, "Well don't think I'm going to get my tits out, and as for the full nudity bit well, you won't catch me anywhere near there at all." I knew my sister wasn't a prude in the slightest and I was a little surprised by her reaction. As for me, well I could look couldn't I?

I went into the bathroom and left Jenny to dry herself and get dressed. She was right, there was precious little room to turn round even, and I found it nigh on impossible to dry myself properly, so emerged dressed as she had been, a towel wrapped round my waist. She was sitting at the small dressing table, wearing a dress and was just finishing putting her make up on.

"See what I mean?" she asked. I nodded, looking around to see how we were going to manage me dressing in front of her. "Give me a second and I'll go and sit on the balcony while you get dressed, I promise I won't peek," she teased. She went and sat on one of the chairs, ostentatiously staring out to sea while I dried and dressed. In all honesty I didn't really care whether she saw me naked or not, but I was prepared to go along with our self-imposed restraint for the sake of her sensibilities.

We found a bar and settled down with some drinks, it was all-inclusive and I was starting to look forward to enjoying myself, I appreciated a beer and tended to avoid drinking shorts as I found I consumed them too fast, but a nice red wine was also on my list of favourites. The clientele was considerably younger than I had imagined, and then it occurred to me that the 'Adults Only' tag was probably the key. Some of the women were seriously attractive and I began to look forward to seeing them around the pool.

The dinner buffet had a wide selection to choose from, all beautifully cooked and presented, and I do admit to eating probably a little more than I should have, I was going to have to be careful about putting on too much weight. Jenny was a little more careful than me, but even she couldn't resist the desserts and I saw her guilty look as she forked it into her mouth.

We were both tired from the journey and so decided to call it a night and wended our way back. Jenny tucked her arm in mine and it felt really nice, we'd not been especially close, but had always got on well together and despite my initial reservations about spending so much time with her, these were fading away.

Back at the cabin I let her go into the bathroom first, she emerged still fully dressed and I left her to get into her pyjamas whilst I went in. I didn't take long and when I came out she was still not in bed. I couldn't help but notice how the swell of her beasts pressed against the top, and the way they wobbled nicely. She got into bed and ostentatiously faced away as I began to strip off whilst she chatted away to me. I stood there, naked and wondered what she would actually do if I just went and got into bed with her like that and just for a minute I was tempted, but then sense took over and I slipped into my pyjamas, the feel of them strange.

I slipped into bed beside her, there was just about enough room for the two of us, but I was surprised when she slithered over to me and pulled me into a hug, giving me a kiss on the lips. "Thank you David for doing this with me, I wouldn't have come on my own and I think I'm going to enjoy it. Good night." She turned away and snapped off the light as I lay there, my mind going over the day. She was right, I decided, I was going to enjoy it as well.

Neither of us slept well, I certainly tossed and turned in the strange bed, and whilst there was no discernible motion of the ship, there were constant noises and in the small cabin and my pyjamas I felt hot and constrained. I tried not to disturb Jenny, and I'm sure she tried not to disturb me, but she did and when I did sleep it seemed fitful and not particularly restful. When I woke it was light, but clearly still early and I would have loved to go straight back to sleep but I could feel my cock pressing up hard against my pyjamas. I had given some thought to what I'd do about my usual morning erections and had failed to come up with an answer, normally I just had a wank, and had rather thought I'd be able to do that in my single bed, but clearly that was not an option now.

Tentatively I wondered if I could manage to rub one out without Jenny noticing, but every time I tried to stroke my cock the bed wobbled alarmingly, and when she snorted then rolled over onto her back, snoring gently I had to give that idea up. I contemplated getting up and going into the bathroom, but if she woke up, she'd wonder why I was in there so long. Two weeks without a wank would be torture for someone used to at least one a day, not to mention very visible erections and my mind fought to come up with a solution.

Jenny stirred and I looked over at her, her face relaxed in sleep mode, it was strange waking up next to her, had she not been my sister I would have stretched out a hand and fondled a breast, perhaps slipped my hand down between her legs and fingered her pussy before making love to her. I found my hand on my cock again and forced myself to release it.

Her breathing changed and I thought she was going to open her eyes, but she just stirred, then I noticed a slight movement in the covers around her waist, were they actually moving or was it just the light? No there was definitely movement there, surely she couldn't be.... At that moment her eyes flashed open and for a second I saw a look of alarm, then she relaxed and a smile broke out on her face.

"Morning," she said, "just for a minute there I thought....." she stopped, "Never mind, did you sleep well?"

"Not really." I replied, "You?"

"Nor me, I hope we get used to it soon, I'm sure we will. Shall I go in the bathroom first?" I agreed and she rolled out of the bed, making her way to the bathroom. The door shut and I grabbed my cock in my fist, stroking like fury, heedless of what I was actually going to do when it erupted. I heard the shower start, water splashing then it shut off, only to start again. I could feel myself getting close and focussed intently, then the water went off again and I knew I didn't have much time.

Just as I could feel my orgasm building deep inside the door abruptly opened and there she was, hair wet, towel wrapped round her as before. I stopped, still holding myself and squeezing my shaft as she tightened the towel and for a second it flapped open and I could see her inner thigh all the way up to her.... what? That was it, the towel flapped back and I was left wondering what I had seen.

"Your turn now," she said and I started to contemplate how I was going to get from the bed to the bathroom with a tent in my pyjamas. Fortunately she turned away to rummage in some drawers and I rolled out of bed and keeping my body turned away from her, managed to get to the bathroom without anything being seen, or at least I hoped so.

Once inside I closed the door and stripped my pyjamas off, struggling in the confined space and bashing my elbows against various walls and partitions, then my hand was on my cock and once more I was rubbing furiously. I stepped into the shower and turned the water on, still wanking frenetically, then I could feel it, rising within me, the frustrations of the past few minutes melting away and then with a glorious surge from within me my cock erupted, spurting my cum all over the shower cubicle and its walls. I stifled a gasp, then allowing my breathing and heart rate to return to normal and I began to shower properly, washing my hair and body, ensuring that I also washed away the evidence of my guilty misdeed.

Finished, I wrapped the towel round me again and emerged to see Jenny tidying up, fully dressed, if casually in shorts and tee shirt. "I'll go out on the balcony again," she offered.

"You don't have to," I replied, but she smiled and headed out anyway.

It didn't take me long to dress and we were soon on our way to breakfast. Once again the food selection was fabulous and it was with some difficulty that I restrained myself from pigging out, but it was still with a full belly that we returned to the cabin. Jenny went straight to a drawer and pulled out what appeared to be her swimming costume and looked enquiringly at me.

"Oh sorry," I apologised, getting her drift, "my turn outside." I went out and leaned on the rail, watching the water sluicing past, itching to turn my head and look in, but not daring to. I half turned and wondered if I could get a reflection but to no avail, then she was calling to me to come in.

"What do you think? It's not too revealing or too young for me is it?" 'It' was a bikini in royal blue and she filled it well, her breasts pressed together in a cleavage and a snug fit round her crotch and bum. In her forties she was no lithe nubile, but I thought she looked great and told her so. "If only I could get rid of this," she pinched the flesh around her waist, to be honest there was a slight roll there, but she'd had two kids and you would barely have known.

"Something to hold on to," I replied, then felt my face go a little red at the implication.

She grinned at me, "Those were the days when there was someone to do the holding."

I pulled my swim shorts out of my drawer and turned away from her, "It's all right Jen, don't go outside." I pushed down my shorts and briefs and slipped them over my feet then pulled my swim shorts on.

"Nice arse!" she commented, "I wouldn't mind holding on to that myself!"

We made our way to one of the pools and found a corner where there were some spare beds, setting our towels out on them. I looked around and saw that at least half the women were topless, all shapes and sizes of breast and nipple on display. Jenny caught my look, "No way!" she mouthed at me. We helped each other with the sun cream and settled down and I found myself drifting.

"Are these taken? Do you mind if we use them?" I jerked my eyes open to see two women of about my age peering down at me. Both were in bikinis and even against the glare of the sun I could see they had nice bodies.

"Certainly not, be my guest." I half sat up as they moved the beds slightly further away and plonked their towels and bags down. I watched through slitted eyes as they covered their lower bodies in sun cream, then they calmly unsnapped their tops and shucked them off, continuing to rub the cream into their bodies. I could see their breasts moulding and squashing under their hands and my cock twitched at the thought. Not now, I prayed, for once in my life wishing a boner away.

Both had a nice pair, one slightly larger than the other and their nipples were similar, just round brown circles glistening under the sun from the cream. Finished, they sat down, "I'm Sarah by the way and this is my sister Helen."

I sat up and offered my hand although my eyes were fixed on their breasts. Realising this I looked up to see a smiling face as Sarah shook my hand. "I'm David and this is my sister Jenny." Both of them looked a little surprised at that revelation although neither made any comment as the three women exchanged polite nods.

"Have you explored the ship yet?" asked Helen, "We've had a quick look around but were planning to get some sun first."

"Likewise," I offered back, "although some of the areas sound more than a little interesting," I continued, thinking of the aft pool and the 'designated areas'."

"Yes, and we rather thought we'd be getting single beds, so were a bit surprised by the double. How are you finding them?"

"Yes, we were surprised as well, but we've managed so far."

Polite conversation over we all settled down and although I kept taking discreet glances at their chests I found that I was starting to get used to the idea of bare breasts right next to me. Quite when the attraction would wear off completely I had no idea, and if I knew how my mind worked it never actually would.

We covered up and had some lunch and I was a little surprised when Jenny announced that she'd had enough sun for the first day and as she was feeling a little tired she was going to have a snooze in our cabin. After assuring me that she was fine, just a little tired, I left her to it and returned to the sun beds. Both Helen and Sarah were still there and looked up as I returned alone. "Jenny's gone for a snooze," I advised them and saw them glance meaningfully at each other.

"We were just thinking of going for a look around, would you like to come with us?"

"Where did you have in mind?"

Another glance at each other, "Well we thought we'd start with the pool on the stern or fantail or whatever they call it, then go from there." I felt my cock twitch at the prospect not only of seeing all those naked bodies round the pool, but these two specifically and found myself grinning.

"Sure, why not?" We left our bags and picked up our towels and headed aft, picking our way through the hordes of sunbathers. We weren't due at our first port of call until that evening and the ship was quite crowded. The aft part of the ship was semi-screened off, two crew members standing at the entrance. They nodded cordially to us as we went past them and the view opened out.

It wasn't a large pool area, but everywhere you looked there were naked bodies. The average age was probably a bit less than for the ship as a whole and some of the figures on display were positively stunning. Of course the opposite was also true, and I was amazed at how some people brazenly showed off bodies that were well past their 'Best Before' date. Still, each to their own.

Everywhere there were breasts and pussies, cocks and balls, a sea of people all enjoying the feel of the sun on their entire body. "Wow!" mouthed Sarah, "Look at that. Let's join them."

"I thought we were just exploring?" I asked, suddenly nervous at exposing my middle-aged body, and more to the point, the erection that I could feel rapidly forming.

"When in Rome...." stated Helen, heading off to a trio of beds she'd spotted, dragging us along with her. I found myself tagging along, drawn by a heady excitement, and couldn't help but stare at everything around me and the two still covered bodies ahead of me. We stopped by the beds and Sarah and Helen looked at each other then as one peeled off their tops and then pushed down their bikini bottoms.

Both were fully shaved and I could see the tops of their slits, neat pussy lips topped by prominent clitoral hoods. My already hard cock stiffened even more and I could feel it pressing hard against the inside of my shorts.

"Come on David, don't be shy."

"But I've got a..." I hesitated.

"So have half the men here, that's what makes it so interesting. Soft cocks are boring." pronounced Sarah. I looked around, she was exaggerating, there were some erections prominently on display, their owners and everyone else for the most part ignoring them, but I still felt embarrassed. Hesitantly I pushed the waistband of my shorts down over my hips and then sat down and wriggled them off.

My cock sprang up, but at least in this position it was only visible to my immediate neighbours. "I don't see what you're worried about, you've got a nice cock," commented Helen, "but if you're worried let me sort it out for you."

Before I could interpret the meaning of her words she had reached forward and had grasped my cock in a handshake grip and was stroking up and down. I think even her sister was surprised as I saw her looking on, a look of shock on her face. My initial instinct was to pull away, but it did feel good to have someone else's hand on my cock and I found myself relaxing into it.

A thought bulleted into my brain, "But the brochure said no sexual activity round this pool." I looked around, but no-one seemed to be taking any notice.

"This isn't sexual activity, it's a medical procedure to stop you getting blue balls. Trust me, I'm a nurse." True or not she was giving me an excellent hand job, her hand sliding rapidly up and down my shaft, every so often her palm would graze over the glans spreading my pre-cum around and sending exquisite feelings through me.

I looked over at Sarah, the shocked look had disappeared, replaced with one of keen interest, no it was more lust and desire, and I saw her hand creeping between her legs to fondle herself gently. I was aware of curious looks from around us, a few men were trying to look on disinterestedly, but some I saw were verging on envy, and some of the women were replicating the look on Sarah's face and I even saw hands sliding towards partner's cocks.

I forced myself to look back at Helen, her breasts were wobbling most attractively, vibrating almost from the attentions of her hand on my cock, something I'd always found exciting. She saw my look and grinned, then very deliberately opened her legs to reveal her pussy in its entirety, broad outer labia, crinkly inner lips and if I wasn't mistaken a little sheen of moisture on them. A gasp came from Sarah, she was trying to be unobtrusive, but I could see the tip of one finger massaging her clit and as I watched one finger slipped slowly into her pussy.

That did it, my balls began to tighten and I could feel my orgasm rising through my body. My eyes flashed a warning to Helen and I felt the tempo increase, then with a soaring feeling inside me my cock erupted, sending a spurt of cum over Helen's hand. She managed to direct the rest away from her, four, five times more then I was dry and her hand continued to massage me softly.

There was almost a collective sigh of relief from all around us as everyone went back to their own business. Sarah's body jerked a few times and little squeaks, barely audible, escaped her tightly shut mouth, then she too was still, a long sigh emanating from her.

"There, that's one you both owe me," said Helen, a smirk on her face.

We spent the rest of the afternoon in and around that pool, and I realised that I wasn't the only one who needed medical handjobs, the staff seemed to turn a blind eye to such medical procedures, only when one couple became a little too adventurous did someone have a quiet word and they stopped, looking rather sheepish. My erection didn't return and I found that I was very much enjoying the sense of freedom that being naked gave me and I started to wonder if I could somehow persuade Jenny that it was a good idea.

When I got back to our cabin I opened the door quietly, half expecting Jenny to be asleep. Instead she was propped up against the pillows thumbing through a magazine. She was dressed in just a bra and panties and my surprise must have shown. "Sorry," she apologised, "I didn't want to crease my clothes and anyway it's no different to a bikini." Somehow it was different, more intimate, but I made no comment.

"Did you have a good afternoon?"

I decided to be economical with the truth, "Yes, I just hung around the pool with Sarah and Helen, they both seemed like nice people. In fact I've said we'll have dinner with them tonight, you know in one of the proper sittings." The idea had in fact been Sarah's and I'd gone along with it and was pleased that Jenny didn't seem put out by the notion.

I showered and returned to the main cabin to get dressed, Jenny didn't offer to go out onto the balcony and studiously looked at her magazine as I dried myself. I did catch a glimpse of her in the mirror staring at me when I pulled on my briefs, but I didn't think she could see anything but my bare arse.

We met Sarah and Helen over drinks and I was pleased that they seemed to get on well with Jenny, they didn't mention anything about the nude pool for which I was grateful, although as I tried to rationalise to myself, I had nothing to hide. We weren't married so what I did was my business as long as it didn't impinge upon her. What I hadn't counted on was Sarah's hand finding its way to my lap during dinner, the mere feel of it on my thigh was enough to give me an erection and when she started to tease the end of my cock with her little finger through my trousers I found it difficult to concentrate.

After dinner we all made our way to one of the club type dance floors and the four of us formed a small group and the three ladies danced elegantly and I probably made a bit of a fool of myself, being blessed with two left feet. During a break Helen leaned in close to me and whispered in my ear, "We're going to go and explore some of the 'designated areas', do you and Jenny want to come with us?" I would have loved to have gone with them, but I didn't think that Jenny would be up for it, certainly not with her brother there, and I certainly couldn't just abandon her, so very regretfully I had to decline. "Another time then," offered Helen as the two of them departed.

Jenny and I danced a bit more, but then called it a night and headed back to our cabin, Jenny let me in the bathroom first and when I emerged still fully dressed I was surprised to see her wearing just her pyjama top, her legs bare. She caught my surprised look, "You don't mind do you, I was so hot last night so I thought I'd try this?" She flashed up the bottom of her top and I could see that she was wearing panties.

"Of course not," I replied, "I might even join you." She nodded and disappeared into the bathroom as I considered how far down I could dress, in the end I decided that just boxers was a bit too far so slipped into my pyjama trousers and got into bed, my hand automatically finding my cock and giving it a quick tug. Jenny came out and slid into bed beside me, once more scooting over to me and pulling me into a hug so I could feel the soft press of her breasts against my bare chest and what felt suspiciously like her thigh on mine.

"They seemed pleasant enough," she commented, "where were they off to?"

"I think they wanted to explore some of the...." I hesitated, "... other areas of the ship."

"Perhaps we should have gone with them?" she remarked as she turned off the light, "it might have been fun."

All I could think of was "Damn!"

We slept a bit better, at least I did and Jenny didn't seem to toss and turn so much, and when I woke she was till sleeping peacefully. I played with my cock for a while, not actually masturbating but just enjoying the sensation of my hand on it as my mind recalled the feel of Helen's hand wanking me off the day before. I realised I wanted to cum, so slipped out of bed and into the bathroom, where I shamelessly masturbated furiously, emptying my balls all over the shower again. When I came out Jenny was sitting up in bed, the outline of her breasts visible against the soft material of her pyjamas. Both hands were under the covers but when she saw me she lifted them out, and just for a second a guilty look crossed her face.

"My turn then." She threw back the covers and slid one leg out, just for a second giving me a good look at the gusset of her panties. I couldn't help it, I tried to visualise what her pussy would look like under the white cotton, images of Helen and Sarah flashing in front of me. I followed her backside into the bathroom, dropping my towel as the door closed behind her. I dressed for breakfast and when she came out made my way out onto the balcony to give her some privacy while she dressed.

Breakfast done we changed into our swimming costumes, each of us doing the 'balcony dance' as we had started to call it, before returning to the pool we'd used the day before. Neither Helen nor Sarah were there, and I assumed they had decided that the nude pool was the best place for them and I started to wonder how I could get back there myself, looking at breasts all day was certainly not to be sniffed at, but naked women was like paradise.

I had a beer at lunch and unusually Jenny had a couple of glasses of wine spritzer. We settled back onto our sun beds and I found it difficult to keep my eyes open, Jenny too seemed to be having the same problem and as I watched her she opened her eyes with a start. "It's no use, I think I'm going to have a nap for a couple of hours. I'll catch you later." She ambled off and I lay back and dozed.

I woke with a shiver, and as I came to I realised the sky had clouded over and the wind seemed to have got up. People were abandoning the pool and it seemed like a good idea to do likewise, so I picked up my towel and headed back to the cabin. I paused at the door, all seemed quiet inside as I flashed the key card at the lock and eased the door gently open so as not to disturb Jenny.

She was lying on the bed, her eyes closed, but she was not sleeping, to my surprise she was completely naked, her breasts wobbling on her chest, broad nipples dark on the ends. Her legs were wide open and I could clearly see one hand thrusting a pink dildo rhythmically in and out of her pussy. Her lips looked swollen and there was a sheen of moisture on them, her other hand was fapping furiously at her clit below a small triangle of dark curly hair.

My cock was instantly hard, pressing against my shorts and my hand found it and squeezed it as her eyes popped open, a look of surprise and horror on her face. "Fuck!" came from her mouth as her body started to curl up on itself, her orgasm clearly upon her. She began to buck and writhe on the bed, unable to stop the waves rolling through her. Her eyes dropped to where my hand was gripping my cock through my shorts, "Let me see it," she croaked and I pushed down the waist of my shorts allowing my cock to spring out. This seemed to set off another wave in her as my hand began to rub furiously along my length, my eyes riveted to the join of her legs and the pink dildo embed in her pussy.

She stopped shuddering and lay back, her chest heaving, seeking oxygen as our eyes met again and with another cry of "Sorry," she rolled off the bed and pulling the dildo out, rushed into the bathroom and slammed the door shut behind her. I stood there, cock in my hand, shorts halfway down my legs, wondering what to do. Slowly I sank onto the edge of the bed, my hand still beating out a steady rhythm, my sub-conscious mind only seeking one end as my brain whirled in a maelstrom of thoughts.

The bathroom door opened and I looked up, Jenny stood there, still naked, her eyes watching intently. I stopped and went to pull my shorts up, "No don't," she commanded, "you've seen me now I want to see you." My hand resumed its beat as she walked over and stood in front of me. Greedily my eyes took in her breasts, tear drop shaped with broad dark nipples, the soft rolls of her stomach and the neat triangle of pubic hair only half covering pussy lips that I could see clearly, meaty crinkly inner lips dangling slightly from her.

I watched as her hand descended between her legs, playing with herself as she focussed on my hand grasping my cock. Faster and faster my fist flew, and I could feel my orgasm brewing inside me, then rising swiftly. I looked her in the eyes and saw she knew. She knelt between my legs, "Cum on my tits," she instructed calmly and then I erupted, my spunk spraying out forcefully in front of me, three, four spurts landing on her breasts and nipples, before slowly dribbling downwards.

She put a hand on each of my knees and leaned forward and for a second I thought she was going to suck my cock into her mouth, but she levered herself up into a standing position. "I think I'd better go and wash this off." She turned and sauntered back into the bathroom, the door shut and I could hear the shower going on as I held my slowly deflating prick in my hand.

Somehow it didn't feel right, sitting on the bed in 'our' bedroom with my shorts round my ankles and my cock sitting limply on my thigh and I pulled my shorts back up, my mind still trying to come to terms with the last 5 minutes or so. I saw my sister in a different light, we'd never really ever talked about our sex lives, and now they had intersected in a way I would never have dreamed of.

The door opened and steam billowed out, followed by Jenny wrapped in a towel. She looked pointedly at my shorts and mouthed "Spoilsport," before releasing the towel. Once again I was confronted by her breasts, her nipples were looking much softer now and between her legs, her triangle of crinkly hair. Quite unabashed she began to dry herself, lifting each breast in turn and then carefully drying between her legs. I made to get up, "I don't think there's any need for the balcony dance any more do you?" she said as she slipped a pair of panties on and adjusted their fit. "There, your turn."

When I came out she was still wearing just a pair of panties, her breasts lolling on her chest as she reclined on the bed reading. She looked up expectantly at me, and I grinned then whipped off my towel to reveal my flaccid cock. "Hmm, l I think I prefer it when it's hard," she surprised me by saying before turning back to her magazine.

We dined in the buffet and took in one of the tribute act shows, they were very good and we had a fabulous evening, followed by a nightcap in the bar and then made our way arm in arm back to our cabin. "I could get used to cruising," commented Jenny, "but I suppose when you have to pay for it, it might be a different story." I followed her into the cabin and went straight into the bathroom. When I came out Jenny was only wearing her bra and panties and was in the process of hanging her dress up. She slipped past me and went in herself as I contemplated what to wear in bed. Pyjamas were definitely out, and I settled on leaving my boxers on, at least then if I got an erection it wouldn't be quite so obvious.

Jenny came out, still in her bra and panties and stood by the bed, then calmly reached behind her and unsnapped her bra releasing her breasts. I could see the marks on her skin left by the straps and she massaged her breasts, squashing them flat against her body as though to get the blood flowing again then with a quick look at me shimmied her panties down and off. A quick flash of pubes and she was sliding into bed beside me.

As on previous nights she scooted across and pulled me in for a hug and a kiss, only this time I could feel her naked breasts against my skin and what I had to assume was her bare pussy on my thigh. I felt my cock twitch as she kissed me goodnight on the lips, then her hand slid down my body to encounter my boxers. "I don't think we need these anymore do you?" she said as she started to pull them down.

"But what if I get an....."

"Then we'll both enjoy it won't we?" I helped her finish getting them off and she tossed them onto the floor beside the bed, then turned away and switched off the light. I had to admit, it felt good to be naked in bed again, but despite our earlier encounter I still didn't feel too comfortable being naked in front of, well actually beside, my sister. That didn't stop my hand finding my cock and squeezing it, but as it began to stiffen properly I reluctantly released it and turned away from her so we were sleeping back to back. I tried hard not to imagine her naked form beside me and must have finally drifted off to sleep.

It must have been in both our sub-consciousnesses because we managed not to touch each other in the night, although for once I did have a really good sleep, waking feeling refreshed in the morning. I opened my eyes to see Jenny apparently asleep on her back, her lips pursing slightly as she breathed.

As was my habit, my hand found my cock, already hard and with a start remembered we were both nude. I was so tempted just to lift the covers to reveal her breasts, my mind trying to remember their shape and form but I controlled myself, although it didn't stop me from stroking my prick very gently. Whilst I was enjoying the sensation I didn't dare get too vigorous for fear of waking her, so it was very much in two minds that I lay there, trying to decide whether to get up and go and have a proper wank in the bathroom or put up with half a job in my admittedly very comfortable and warm bed.

The attraction of a proper wank proved too much and carefully I rolled over until I was in a sitting position on the edge of the bed. "You don't have to go in the bathroom if you want to masturbate. You can just do it here if you want." The soft voice from behind me made me spin round to see Jenny smiling at me. "I know that's what you've been doing but don't feel you have to because of me. I might even join you."

"What do you mean? "I replied, shocked that she knew.

"Oh come on David, it's been obvious what you've been doing in there, and I've even got myself off a couple of times thinking of you in there. Just get back into bed and enjoy it like you would at home."

Somewhat embarrassed I rolled back into bed, ensuring I was completely covered up and held my cock, just moving my hand slowly up and down the shaft, trying not to disturb the covers too much. Jenny had both of her hands under the covers, but I couldn't see any movement to indicate she was engaged in any similar activity. That was until a soft moan broke from her lips and she looked sharply across at me, "Sorry, I can get a bit vocal sometimes and that was just too much to hold in." My mind went into overdrive as to what she had done to cause that and a frisson of excitement ran through me and I began to stroke myself with a little more vim and vigour.

"That's it." she encouraged, "Don't hold back." Suddenly the covers were pushed back and there were her breasts, pooled on her chest, nipples prominent, the soft flesh quivering slightly. I felt another frisson run through me as I realised she had both hands between her legs doing something that was clearly turning her on. Both of us lay there for a while, each wrapped up in their own individual thoughts and activities, then I could see Jenny's hands start to gain in pace and intensity and another gasp came from her mouth.

Our eyes met and then I saw hers drop to my waist where the noticeable bump in the covers was moving quite rhythmically up and down. Her intent was clear and I pushed the covers down below my waist until my cock was revealed, grasped firmly in the fist that was rubbing steadily up and down. I heard her take a sharp intake of breath, then she too pushed the covers down.

As I'd surmised, both hands were busy between her legs, one appeared to be thrusting several fingers into her pussy, the other was rubbing briskly on what I assumed was her clit. Whilst I couldn't see her pussy in any detail I could see her triangle of pubic hair and could hear a squelching noise. Our eyes met again and a grin spread across her face, "Race you," she said.

It was a fair bet, I was already very aroused and could see that she was as well, and the sight of her quivering breasts and her hands was doing nothing to dampen my excitement. I could feel the bed vibrating and rubbed my cock even harder, my fist tight round the shaft, then I heard her take several very short sharp breaths and then her hips started to lift off the bed and a keening sound escaped her throat and I knew she was cumming.

Frantically I rubbed myself, my hand a blur then I could feel it, starting low in my scrotum, rising rapidly, that feeling of my cum shooting upwards until the end of my cock erupted, a huge jet spurting up onto my chest, followed by another and a third as my face screwed up into a rictus. I glanced to my side, Jenny was lying back, gasping for air, her eyes fixed on my cock as her fingers slowly played with her pussy.

"Call it a draw?" I half wheezed and she laughed.

"OK, but that means we'll need a decider at some point."

"Fine by me!"

We showered and had breakfast then went on one of the excursions into the port we had reached overnight. Interesting though it was, the heat was intense and we were both glad to get back to the ship in the early afternoon. "Let's go and cool off in the pool," suggested Jenny and we slipped into our swimsuits, both of us now getting comfortable with the other's nakedness.

There weren't many people round the pool, most I suspected were either still ashore or having a nap in their cabins. I made my usual surveillance of the collection of bare breasts and then turned back to Jenny to see that she too was topless. She looked at me and shrugged, "When in Rome...."

"That was yesterday," I countered, "this is Piraeus."

"You want me to cover up again?" I shook my head and relaxed back to continue to take in the sights.

It was just about packing up time when Jenny turned to me, "Have you been to the nude pool?" I recalled my visit with Helen and Sarah and nodded. "What's it like?"

"Much like this actually, but everyone is naked."

"Completely?"

I nodded, "Yes, you are supposed to take all your clothes off before they let you in."

"Can we go and see it?" I looked at Jenny in surprise, it had never really occurred to me that she'd want to go there, but I wasn't going to deny her wish, so we gathered our things and headed off to the stern of the ship. There was a head high impermeable barrier, affixed to which was a notice, "No clothes beyond this point." Jenny looked at me and for a second I thought she was actually going to strip off, but she turned to the crew member standing 'guard' and in her sweetest voice asked if she could just take a peek.

He explained that really she had to disrobe, but finally she got her way and he allowed her just to go just beyond the barrier. "I see," she said as she returned, "It's not quite how I imagined it would be, it actually looks quite nice."

"Do you want to go in?" I offered.

"No, I don't think so." We went back to the cabin and showered and changed for dinner. She seemed thoughtful all evening and quiet which was odd for her, but we still managed to have a good time watching one of the shows and when we returned to our cabin she once more stripped naked and got into bed, cuddling up to me for our usual good night hug and kiss.

I woke to an empty bed and the sound of the shower and the first thought in my head was one of disappointment that we seemingly weren't going to masturbate together again. It didn't stop me starting to stroke myself though as I pictured her in the shower, water cascading over her breasts and down between her legs.

I was just starting to get into it when the shower stopped and I looked up, expecting her to emerge, my mind wondering if she'd be naked or with a towel round her. In actual fact it was quite a while before the door opened and I was getting close to my orgasm. Instinctively I stopped, not sure how or whether I should continue. She was wrapped tightly in a towel and came up to the bed and stood right beside my head. "Can you help me with something personal?" she asked tentatively.

"Of course," I replied, removing my hand from my cock.

"I noticed that everyone round the nude pool was shaved 'down there' and I decided that perhaps I should try to blend in, so I've tried to shave, but I just can't do it and I'm worried I might cut myself. So will you do it for me? After all you shave every day."

I stared at her truly lost for words before managing to stutter, "Well, if you really want me to, but I've never done it before either."

"Well that makes two of us, and it will surely be easier for you to do it than me." She turned round and went back into the bathroom returning with her lady razor and some nail scissors. "I thought you could cut off most of the hair with the scissors and then use the razor." I agreed that seemed the most sensible way forward and she dropped the towel and spread it out on the bed. "Come on then, out you get, you can't do it lying in bed."

I went to roll out of bed, then remembered my erection, "I've got an errrr....."

"Oh ignore that, it'll give me something to take my mind off what you're doing." I stood up, my cock sticking straight out in front of me, conscious that she'd never actually seen it like that and she sat down on the edge of the bed, my cock only feet from her face. She looked at it then lay back on the bed and opened her legs.

There before fully exposed for the first time was her pussy, broad, slightly darker outer lips and the meaty crinkled inner lips that I'd glimpsed before, with just the hint of pinkness showing inside. I could see her clit, a little button tucked in the folds of its hood and for a moment I couldn't help but stand and stare. "Just get on with it David, this is almost worse than being at the doctor's." She'd made an attempt at cutting some of her pubic triangle off, and I picked up the scissors and started snipping away, still conscious that my cock was a hard as granite, and I desperately wanted to rub it.

Finally we were down to the stubbly residue. "Have you got any shaving foam?" I asked, she looked at me as though I was mad, and I got up and fetched mine from the bathroom, my cock swinging threateningly from side to side as I walked. I knelt back down between her legs, my face perilously close to her and squirted some foam over her pussy.

"Do you want to rub it in or should I?" I asked hesitatingly.

"Just get on with it!"

Tentatively I started to spread the foam over her pussy, I couldn't help it, my fingers had to brush her skin and I felt Jenny twitch a couple of times, but then I heard a gasp. "Sorry, I think I'd better finish that." Her hand went between her legs and efficiently spread the foam evenly around.

"Right here goes," I announced, "keep perfectly still now, I know it's a safety razor but I've lost count of the times I've nicked myself."

"Thanks." came the tart reply, "That fills me full of confidence."

I started on the easy bit, her mons and found it was in fact little different from shaving my face, then I started lower. I found my face getting closer and closer to her as I ran the razor over her outer labia, the light hair coming off easily. Then the more difficult bit. I angled the razor this way and that but couldn't really workout how best to get into those little crevices.

"I sorry, I'm going to have to touch you." There was no reply so I extended a finger out and spread her pussy lips to one side garnering a soft moan. Carefully I eased the razor along, then did the other lip. All seemed well and I suggested she wipe off the residual foam with the towel. That revealed that I hadn't been as thorough as I had thought and it needed another go.

This time was easier, I used my fingers to spread the foam, running them gently across her pussy, even penetrating into her lips slightly. It was causing hell with my erection which was starting to hurt a little and I knew I was going to have the mother of all wanks when I was done. Jenny was moving a bit and I had to admonish her a little.

"I can't help it, it's doing things to me." I didn't enquire what those 'things' might be, but when I detected a little trickle of clear juice between her lips I had a pretty good guess. I could see her tongue protruding from her mouth slightly, lightly clenched in her teeth and she seemed to be having some difficulty breathing properly, but I soldiered on, parting her pussy with the fingers of one hand as I handled the razor with the other. Finally it was done to my satisfaction and I picked up the end of the towel and wiped away until all the white foam was gone.

I sat back on my haunches and admired my handiwork, "There!" I announced, "Smooth as a baby's bum and as pretty as a picture."

I don't know what I was thinking, but somehow as if with a mind of its own, my head leaned forward and planted a kiss on her pussy, my lips making solid contact. I tasted soap and something else as a long groan came from her. Still maintaining contact I looked up at her face, she had her eyes shut but opened them as we made contact. "Sorry," I apologised instinctively.

"Don't be, and don't stop, no-one's done that to me in far too long."

A little tentatively I returned my lips to her pussy, pressing a little harder, then flicked my tongue out between her lips. She gasped and I felt a surge of something tangy on my tongue as her hips pushed her vulva harder up into my face. I could see her hands gabbing the bed covers and could sense the tension in her body as the unaccustomed sensation spread through her body. Gradually she relaxed and began to undulate her hips, pushing up against me. I matched her rhythm and started to slide my tongue along her slit, each stroke seemingly eliciting a fresh surge of juice from her pussy.

I found the opening and pushed my tongue hard in, another gasp and almost a lunge upwards with her body, followed by a long soft sigh as she subsided again. I was having trouble maintaining a steady contact and cupped my hands under her bum, pulling her steadily against me. That made it easier and I resumed my steady licking, running my tongue almost from her arsehole upwards to her clit.

I saw that little bud was hard and flicked my tongue over it, teasing and tantalising then her hands suddenly dropped and grabbed the sides of my head and I was no longer in control. She had taken over and was shoving her body into my face, sliding her pussy over my mouth and face in general as I tried to exert some measure of control over what I was doing. I forced my tongue energetically into her, my lips pressing hard against that soft and ever increasingly wet flesh, then I started to feel a change in her, her body almost vibrating, quivering against me and a low keening sound came from her throat.

I pushed two fingers deep into her pussy, opening her up and twisted them hither and thither and the keening turned into a scream as she went into convulsions, writhing and juddering on the bed. One last shudder and she collapsed back onto the bed, still except for the rapid rising and falling of her chest.

I pulled away and took in the scene in front of me, Jenny's breasts were flat on her chest, nipples looking red and angry, her now bald pussy covered in a mixture of our juices, labia swollen and plump, the pinkness inside showing between them. I realised my hand was on my cock, stroking it and I began to masturbate with purpose, knowing I was not going to last long.

"Don't do that," came an instruction and I looked up at her to see her looking at me. I stopped, unsure as to what she meant, as she sat up and pivoted off the bed. "Let me take care of you now." She guided me to my feet then sat me down on the bed as she knelt between my legs, my rock hard cock inches from her face. She grasped it and began to rub it vigorously, the sensation of someone else doing it making up for the lack of control that I would be able to exert myself. I'd take a handjob over a wank any day I thought.

I lay back, my head just propped up, watching as she concentrated on what she was doing. I could see my foreskin covering then exposing my cockhead and it felt almost as though my cock was going to burst, so hard was it. She paused and swapped hands, something I'd never been able to do and then I felt it, a finger pushing up against my arsehole. Instinctively I clenched tight, "Relax." she commanded, "Trust me." I tried to, it wasn't easy, but then I felt her finger slip into my tight hole and my orgasm burst upon me, my cock spewing cum seemingly everywhere.

Most of it went over Jenny's face and chest, some in her hair, then to my amazement she opened her mouth and took me inside for the last few drops. Her mouth felt heavenly, almost like being in a pussy as she milked me dry. She sat back on her haunches and wiped her mouth with the back of her hand, as a smug grin broke out across her face, reminding me of the cat that had got the cream.

"Haven't done that in a while," she commented, "I think I need to improve my aim!" She gestured to the white globs of cum all over her and we both burst out laughing. I let her go into the bathroom to clean up, then had my shower and all dressed we headed out for breakfast. Something had changed between us, there was a closeness that wasn't there before, a shared secret, something more than the relationship between brother and sister.

We changed for the pool and made for the upper desks, but when we emerged onto the pool decks Jenny took my hand and said, "This way." I followed her lead and soon we were outside the nude pool area. "Come on, before I chicken out and change my mind." We stepped past the crewmember and into the area where everyone disrobed. Off came her cover-up and then her bikini top, her breasts spilling out.

Together we pushed our bottoms down and stood there, we'd been naked together before, but not in public and I wondered how long it would before I got a hard-on. As casually as possible we sauntered into the pool area, eyes wandering everywhere to see who was looking. Surprisingly no-one seemed to bat an eyelid and we found a couple of sun loungers and settled down. "Phew!" remarked Jenny, "Made it!"

I found myself relaxing, and I could sense the tension leeching out of Jenny. She kept her legs pressed tightly together, her newly shaved pussy barely visible, but after a while she allowed herself to relax and pretty soon I, and the rest of the pool, could see the whole of her slit. I managed to control my erection, at one point a rather attractive woman in front of me got up onto all fours and I had the most wonderful view of her arsehole and pussy between her legs and my cock started to make its presence known, but a quick dip in the pool sufficed to control that.

Mid-morning I was almost dozing, when a voice permeated my consciousness. "Hello stranger, haven't seen anything of you for a while." I opened my eyes and found myself looking straight up into the pussies of Helen and Sarah and my cock gave another twitch at the sight and the memory of the handjob I'd been given. They perched on the edge of our beds and we renewed acquaintances, all the while my cock was starting to betray me.

"Anyway, we'd better be going, if you need a hand with anything just let us know," Sarah gave a knowing look at my cock then Jenny, the implication clear. I watched their backsides sway as they walked back to where they were sitting, joining a couple of men with whom they seemed more than on a nodding acquaintance.

We had lunch at a snack bar by the pool, most people covered at least their bottom half up, although some sat quite brazenly naked at tables or on stools. In the afternoon I couldn't help it, I did snooze a little as did Jenny, half dreaming, half imagining doing all sorts of things with Jenny, Helen and Sarah, my semi-conscious mind confusing them.

We packed up for the day and as we walked back to our cabin Jenny remarked that she'd had a lovely day and perhaps we could do the same the next day? I looked at her in surprise as she continued, "Although I don't know if my stubble will have grown sufficiently to warrant another shave."

We dined in a buffet, returning to our table with plates laden with the excellent food. Just as we were about to eat Helen and Sarah and the two men from the pool arrived, "Do you mind if we join you?" It would have been churlish to refuse, and anyway they were pleasant company. The two men introduced themselves as Mike and Paul.

"They've actually had to pretend they're gay to get on board as they only let 'couples' on board, but I can assure you they are very definitely not," explained Sarah, reaching down with her hand into Mike's lap. He leaned across and gave her a kiss as though to reinforce the message. Like the two women they were very pleasant and over a couple of drinks after the meal they suggested we all moved to one of the nightclubs on board. I wasn't sure that Jenny would want to, but she surprised me by agreeing readily and we headed down to the appropriate deck.

It was quite dark in there but there was plenty of room and we settled in and got some drinks. The four others immediately headed to the dance floor and Jenny looked at me expectantly. "Come on David," she exhorted me. Reluctantly I got up, but soon found I was enjoying myself, all of us dancing in a group.

The music changed and before I knew it I was clasped in Jenny's arms, her body pressed into mine. Somehow that seemed more intimate than being naked with her round a pool and I found my cock starting to press against my trousers. Awkwardly I tried to hold my body away from her, but it seemed almost as though she was pushing against me and I was relieved when the tempo picked up and we separated again.

We sat for a while, taking a break and having a drink, but it was difficult to talk over the loud music and when it all slowed down again, Mike stood up and taking Jenny's hand, led her onto the dance floor. Helen followed with Paul and Sarah pulled me up. If I'd thought Jenny was dancing close then Sarah was almost trying to absorb me. Her body was soft and lithe and I could feel every part of it against me, her breasts pushing into my chest and it seemed her legs were parted round one of my thighs, rubbing against my muscle.

I knew it would happen and it did, my cock started to get hard again and I knew that Sarah could feel it. She'd pretty much abandoned my thigh and was now rubbing what I could only assume was her pussy against the bulge in my trousers. I looked over for Jenny, hoping she'd be able to rescue me, but she seemed to be dancing as close to Mike as I was to Sarah. To my consternation Sarah's hand slipped between us and started to fondle me, making me even harder.

She grabbed my hand and pushed it to her breast, she didn't seem to be wearing a bra and I could feel the softness of her flesh in my palm. "That's better, I've been wanting to get to know this better since I saw it that day at the pool. Why don't we go and have some fun somewhere?" I looked round for Jenny again, she had broken away from Mike and was heading back to our table, in all honesty I would have loved to go with Sarah, but I knew I couldn't just leave my sister on her own. Her eyes met mine momentarily and I read the signal, she'd had enough.

"I'm sorry, I can't," I explained to Sarah, "it wouldn't be fair on Jenny." I broke away and returned to our table, followed by Sarah and the other two.

"How about we go to Cornucopia?" suggested Helen, her arm round Paul who seemed to be sporting a rather large bulge in his trousers.

"What's that?" asked Jenny.

"It's through there." She indicated a pair of doors at the end of the room where two bouncer types stood. "It's one of the designated areas for swinging on the ship."

"What?" exclaimed Jenny.

"Don't worry it's strictly couples only and you get a choice, you can either take a green wristband or a red one. Green is if you are up for anything with anyone and red is if you just want to soft swing with your partner."

"I don't think so," said Jenny, pleasantly enough although I could tell she was a little shocked, "Perhaps another night."

"Well we're off," announced Helen grabbing the others, "Are you sure?" I nodded and they headed off to the doors, the bouncers opening them to allow them in.

I took Jenny by the hand, "Come on. Let's go back to the cabin."

She was quiet on the way back, and when I opened the door and let her in she took me in her arms. "Did you want to go with them? I wouldn't have minded and I don't want to spoil your holiday. I've got no claim on you and....."

"Shush." I held her tight. "Don't worry, I'm happy being with you." I released her and she went to the dressing table to remove her jewellery and make-up as I headed for the bathroom. When I came out she was still quietly busying herself, but got up and we slipped past each other as she went in. I undressed, the usual debate as to what I wore going through my head, but finally off came my boxers and I slipped naked into bed, my hand finding my cock and giving it a squeeze as I thought about the feel of Sarah's breast in my hand.

The bathroom door opened and out came Jenny looking a little happier. She unzipped her dress and slipped it off, carefully hanging it in the wardrobe while I admired the look of her bum from the rear. Off came her bra, her by now fairly familiar breasts dropping free of their support. My eyes switched to them, Jenny saw and smiled, "Men!" she mouthed as she massaged them. I thought that was it as she approached the bed and pulled back her side of the covers, but then she straightened and slipped her panties off, running her hand tentatively between her legs. "It feels different somehow," she commented as she stretched the skin upwards and my cock twitched in my hand.

She slipped into bed and immediately slid over to me, putting her arms round me, her breasts free on my chest and her pussy on my thigh. "I've had a lovely day, and I'm sorry if I've spoilt the end of it for you. Perhaps you'll let me make it up to you?" I was about to protest the lack of need to do any such thing, but she forestalled me by planting a kiss on my mouth, a kiss not as a sister but as a lover might, her lips working against mine. I was a little taken aback and it took a second or two before my body started to respond to her, by which time I could feel her tongue pushing into my mouth, making contact with mine and sending little tingles along it.

She broke contact and looked me deeply in the eyes, then returned her mouth to mine before starting a trail of kisses down my body, over my chest, her tongue brushing over my nipples. She threw back the covers to reveal my cock, by now semi-erect, still in my hand. "I see you've started without me," she mock complained, her mouth getting nearer and nearer to my waist and what lay below it. Gently she removed my hand and replaced it with hers, much smaller but much more arousing than mine, she began to slide her hand up and down my shaft, the blood flowing rapidly into it now as it stiffened considerably.

I made one last attempt at protest, "Jenny, you don't...."

"But I want to, and if I'm honest, it's all I've wanted to do since this morning." She placed a kiss on the tip, then all along it and back again before opening her mouth and sucking me right in. The breath caught in my throat at the sheer intensity of the sensation as she took me right to the back of her mouth. I felt her throat briefly before she drew me out again, her lips tight round my girth, then her tongue swirled round the crown and I was being sucked back in again.

I could feel her breasts resting on my body and slipped a hand under one, feeling the weight in my hand and the hardness of her nipple in my palm. She paused in her sucking just long enough to lift her head and give me an approving look before her head went back down again resuming its bobbing up and down.

I let her breast go and ran my hand over her bum, allowing my fingers to trace along her crease, I found her bum hole and teased my fingertips round it, then further down they encountered her pussy, the soft folds already damp. Gently I eased them apart and pushed a finger into her pussy, causing a brief hiatus in her bobbing before she shifted position slightly to allow me greater access. I took full advantage and slid another finger inside her, feeling how wet and warm she was. I was wondering just where all this was leading when she released my cock from her mouth and sat back on her haunches as though she was having the same mental process.

She swung a leg over my thighs, facing me and for a moment I thought she was going to impale herself on my cock, but settled herself just below it and took it in her hand, rubbing briskly up and down. From my position it looked almost as though it was hers, sticking up between her legs, but I knew from the sensations running through me that it was still firmly part of me. I could see her breasts jiggling on her chest, her nipples protruding dark and round and I was almost mesmerised by the sight.

Down between her legs, I could just see past my cock to her pussy lips, stretched open by her position and at the top her clit, a small hard bud part-hidden in the folds of skin round it. It was something I'd never dreamed of seeing until we came on the cruise and I knew our lives would never be the same again.

I felt her hand begin to move faster, then she swapped hands and again I marvelled at her apparent ambidexterity as something stirred deep inside me and I knew that it wouldn't be long before I was swamped by my orgasm. I could feel it growing inside me and I found myself pushing up at her with my hips, encouraging and exhorting her, she smiled down at me and picked up the pace and intensity more and then I could feel it rising rapidly, my balls tightening and with a final thrust upwards my cock erupted.

Whether by chance or skill she managed to get most of it on my stomach and chest this time as she carefully milked me dry until the spurts had ceased and I was still. She released my cock and examined her hand, covered in white goo. Impishly she licked her fingers and mock smacked her lips. "Mmm, less alcohol and more sugar I think, and perhaps a hint more seasoning." She offered her hand to me to taste, but I declined, never having tasted my own semen nor ever intending to. Pussy juice yes, spunk definitely no!

She reached down and picked up her abandoned towel and wiped me clean then dropped it back on the floor and eased herself off me, settling back down into the bed and pulling the covers up over us. She turned her back to me and pulled my arm round her so my hand was cupping her breast, then switched off the lamp leaving us in darkness.

"Don't you want to....?" I asked.

"No, not tonight, that was all about you. Another time it will be about me, but not now."

She fell quiet and soon I could hear her regular breathing, I knew I should release her but couldn't, wanting to bask in our new found closeness, and pretty soon I was asleep as well.

I slept well, although not without interruption, moments of brief wakefulness, half-remembered dreams of an erotic nature, then I was semi-aware of one happening in real time, my cock was hard and I was trying to make love to someone, I couldn't tell who, a confusing mixture of Jenny, Helen and Sarah with Mike thrown somehow into the picture.

My hips were moving but I couldn't find the pussy I was trying to penetrate and I was getting increasingly frustrated as my cock slipped up and down. The body half under me shifted and then I felt my cock engage and I pushed in feeling it enveloped in a beautifully warm wet sheath. Instinctively I began to thrust in and out as my dream lover groaned and moaned beneath me.

More consciousness returned and I realised my face was buried in a mass of hair and I pushed it out of the way to see who she was. With a shock I realised it was Jenny and I was fully awake and my cock was actually buried inside her.

With a jerk I pulled out of her and began to apologise, "Jenny, I'm so sorry, I didn't...."

She spun round in bed to face me, "David, don't fret, I know you were asleep, but I wasn't and I was actually really enjoying it, so why don't you just continue what we were doing and enjoy it properly." I felt her legs part and her hand reached down for my cock and drew me back down until I was positioned between her legs, nudging at her soft folds.

"Jenny are you sure?"

"Never more so David, now just make love to me." She guided me forward and I felt my cock part her lips and slide back into that welcoming haven, pushing right in until our bodies were tightly pressed together. "There, now we can enjoy it properly." I felt her hips start to undulate and I matched her, my cock began to slip easily in and out of her, sending waves of pleasure through my body as we found a comfortable rhythm.

I could scarcely believe what was happening, one minute I was immersed in a dream, the next I was buried balls deep in my sister's pussy. A pussy that was every bit as welcoming as any I'd been in. "It's all right David, you won't break me." I realised I had been metaphorically tip-toeing and encouraged by Jenny's words I started to thrust harder into her, our bodies clashing together. I could feel her squeezing me with her pussy muscles, and each inward thrust was met with a tightening round my cock and a small grunt from her mouth.

"That's it Davey, fuck me harder, shove that lovely cock of yours into my pussy, fuck me hard until you cum in me and fill my cunt up with your hot thick spunk." If I was having difficulty believing what was happening, I was having even more difficulty believing what I was hearing, my normally mild mannered sister had a potty mouth when it came to sex. It seemed to be doing something for her anyway, her body was really thrusting up against mine now, and her hands were like talons in my back.

I raised myself up on straightened arms, changing the angle of penetration and found I was deeper inside her, I could feel the end of my cock bashing on her cervix and see her breasts oscillating on her chest, nipples engorged with blood dark in the centre of the mass of quivering flesh. Her head began to roll from side to side, her breath coming in short sharp bursts and I could see a red flush spreading across her chest.

A look almost of desperation appeared on her face, matched by an increase in the intensity of her undulations and I began to thrust even harder into her, increasing the pace. I lowered myself down once more and remembering when she'd cum when I was shaving her, I slipped a hand under her bum and found her crease, my fingers seeking her tight hole. I found it and pushed hard against the centre, an initial resistance and then it slipped in.

Her body went immediately rigid as her orgasm rushed over her and I could feel her pussy clamping hard round my cock as my finger was trapped in her arse. Then she began to judder, almost uncontrollably, her face went bright red and her features screwed up tight, little gasps and grunts coming from her mouth as I held her tight and her orgasm slowly abated.

Her face relaxed and her eyes opened. "I haven't cum like that since... well for a very long time. I'm sorry if I got a bit vocal, I know I can sometimes, I hope you weren't upset."

"No not upset at all, just a bit surprised, that's all." I started to move again, just gently rocking my hips, sliding my cock slowly in and out of her pussy.

She looked up at me, "You haven't cum?" I shook my head and a broad grin broke out on her face, "Well that means I get to go again then, let me do some work." She wriggled out from under me, my cock slipping from her pussy, then with an impish grin bent forward and sucked me deep into her mouth, "Mmm, tastes of pussy," she announced, then as she had the night before she slipped a leg over my thighs and knelt above me. This time she didn't settle on my thighs, but still holding onto my prick she slowly lowered herself down.

I could feel the softness of her folds, then the entrance to her vagina as my cockhead opened her up and I slipped easily inside, as she enveloped me until her body was once more resting on mine. She began to rock her hips, sliding me in and out of her, each time sending waves of pleasure through my body. Instinctively I matched her movements, pushing up gently each time as we moved tenderly together. Her breasts rolled enticingly on her chest and I reached up to cup them, brushing my thumbs over her nipples.

She cupped her hands over mine and pulled them tight against her body, "I prefer these to a bra," she commented.

"Well any time..." I offered.

We continued to move gently against each other, I had been on the brink of my own orgasm when Jenny came and I could feel it rising in me again and my body started to push up harder. I slipped my hands down to her hips and held them there, guiding and lifting as our movements gained in intensity. I could see my cock splitting her lips, a creamy substance oozing from the sides, flecked with tiny bubbles, then my view was partially obscured as Jenny's hand descended to her clit and started to rub it, fingertips just describing small circles round and round, then her fingers would split and she rub up and down round my cock.

She was using her muscles again, squeezing me and I knew that I was not going to last long. I began to thrust harder up into her, our bodies slapping together in the moisture secreting from her pussy, lubricating the way. She wasn't tight by any means, but her pussy wrapped around my cock like a well-worn and comfortable glove. Little noises escaped her mouth, sighs, grunts and gasps and I could see her teeth biting on her lip.

Then I could feel it deep inside me, there was no going back now and I looked desperately up at her, my eyes passing a silent message. A message she received as her pussy tightened round me and she started to ram herself harder and faster down onto my prick. Then it began to boil up, rising from the depths of my balls upwards and my cock exploded deep inside her, spurting cum forcefully against her cervix.

Her head went back and a cry escaped her, and I could feel her pussy pulsing round me again, my cries mixing with hers as my balls continued to empty into her. Then we were both done and she collapsed on top of my chest, her breasts pressing against me. Slowly our bodies returned to normal and I could feel my cock softening and slipping out of her, then with a 'plop' it fell right out onto my thigh accompanied by a healthy dollop of warm cum.

She rolled off and lay beside me, her chest still rising and falling rapidly. One foot was pulled up against the other knee and I could see her pussy lips glistening with our combined fluids. Then a white blob emerged from between them. She caught my look and peered down between her legs, dropping her hand to scoop up a dollop on her fingertip. She brought it to her mouth and licked it, then cleaned her finger off between her lips.

"Sugar intake is fine now, but still needs more seasoning!"

Laughing I pulled her in for a hug and our mouths met in a tender kiss, then she rolled over on top of me, depositing another large glob of cum on my stomach before standing up beside the bed. "I'd better go and get this cleaned up." She held her hand between her legs and waddled off to the bathroom, but didn't close the door and I could just see her knees as she sat on the toilet, then I heard the splash of her pee into the bowl.

She stood, once more in my view and wiped her pussy with a wad of paper before tossing it in and flushing. Then she clambered into the shower and the water began to flow. I lay there and watched her, the water splashing on the shower screen blurred the detail, but I found it fascinating and more than a little erotic watching her, I could see the shape of her breasts moving under her hands and the brisk rubbing between her legs and despite my earlier orgasm I could feel my cock stirring. My hand went to it and squeezed it, bringing it to a state of semi chub.

A wank would have been nice, but I refrained, just enjoying the feeling of hand on cock. She stepped out of the shower and wrapped herself in a towel then came and stood by the bed, looking down at my semi-erect cock clasped in my hand.

"Is that all you can think about?"

"With you around yes!" I answered honestly.

"Well save it for later, now go and have a shower and let me watch you." Obediently I rolled off the bed and got into the shower, making a great play of rubbing my cock before getting out to see Jenny sitting watching intently, a broad grin on her face.

After breakfast we headed for the nude pool and found a couple of sun beds. We got a wave from Helen and Sarah who were already there, alone this time, and settled down to enjoy the feeling of the sun on our bodies. My nakedness was starting to feel almost comfortable, certainly there seemed to be no more shyness between us, but then given what we'd experienced over the last couple of days there was little surprise in that. One feeling that did surprise me a little was a degree of impatience, of wanting the day to come to an end and I realised it was because I wanted to be alone with Jenny again, to make love to her again.

I didn't feel confident enough in our new found closeness to suggest that we leave the pool and head back to our cabin for a session, but as I looked at her naked body I found I just wanted to be close to it, to explore it further, to give her more pleasure. My cock twitched at the thought, my mind visualising my cock in her mouth, in her pussy and kissing her all over and I could feel the blood slowly engorging it.

"I need a swim, fancy coming?" I asked.

"Always," she replied with a twinkle in her eye and I wondered if it was a deliberate misinterpretation of my question or totally innocent. I stood up and helped her up and we weaved our way through the sun beds to the pool. There was a huge range of bodies on show, but everyone seemed to be comfortable in their own skin, no-one embarrassed by a roll of fat or saggy boobs. Of course there were one or two who cried out 'Look at me', but overall it was just a very pleasant atmosphere.

We got into the water, it had just the right amount of chill and my cock started to deflate and after swimming a couple of short lengths I just hung against the side, watching Jenny swim a bit more. "You missed a good evening last night, Cornucopia is really good fun." I turned to see Helen beside me, her breasts just bobbing gently below the surface, "Is there nothing I can do to persuade you and Jenny to come with us." Something touched my cock and I realised it was Helen's hand encircling it and despite the water temperature it started to swell again.

"Mike and Paul loved it and we're all going again tonight, it would be really good if you could join us." She took one of my hands and guided it between her legs. I could feel the softness of her pussy as she pushed one finger into her.

"I don't know, I'll have to talk to Jenny about it," I replied, torn with indecision.

"She's your sister, it's not as though you're fucking her." Guilt flooded my mind, Helen was right, she was my sister and I shouldn't be having sex with her. The offer from Helen and probably Sarah as well was there for the taking. As I was musing, Jenny swam up, accompanied by Sarah and I wondered if it was a deliberate two-pronged attack.

"Think about it," ended Helen and I watched as the two of them started up the step ladder to get out of the pool. Water cascaded from Helen's body and as I looked up I could see right up into her pussy and there between her legs was a shining red jewel. Realisation hit me hard, she was wearing a butt plug! Sarah followed and as I looked carefully she too had a pale blue gem.

"That must feel awfully uncomfortable," I commented without thinking.

"Oh, I don't know," countered Jenny, clearly having seen the same as me, "at least they look pretty."

We both got out, politeness decreed that I let Jenny up the steps before me, and although I tried not to look up between her legs I couldn't help it and much of the good work at keeping my erection down was lost.

We had lunch at the snack bar and as the afternoon progressed Jenny announced that she had had enough sun and was heading back to the cabin. Immediately I wondered if she was going back to masturbate, I said I'd hang around for a bit longer, but soon tired of being on my own and headed back myself. When I opened the cabin door I peered tentatively round the door just in case, but to my surprise Jenny wasn't there. Just as I was wondering where she'd got to she appeared, explaining she'd been tempted by a little shopping on the way back.

We showered and changed for dinner, and having opted for 'proper' dining headed for the main restaurant, pausing at one of the bars for a pre-dinner cocktail. Jenny was wearing a knee length dress with a shallow neck and a tight waist and I couldn't help but notice how nice she looked in it. We found some bar stools by the bar and hitched ourselves up and onto them, I noticed that Jenny seemed to be having some difficulty in getting properly settled and gave her a steadying hand receiving a smile in thanks.

There was no sign of Helen or Sarah and I was secretly glad, there'd be no pressure on going to Cornucopia, and I could look forward to a pleasant evening and, I hoped, night with Jenny. We moved into the dining room and took our seats round the table with several others, and I noticed again that Jenny sat a little tentatively. "What's up?" I whispered, "You haven't burnt your bum have you?"

"Something like that," she whispered back, "I'll be fine soon."

Dinner was excellent, whilst the buffets were good there was nothing like being waited on and the food was of a high quality. Our dining companions were all a bit older than us, but there was a pleasant round of conversation at the table and although my mind kept wandering off to what tonight might bring with my sister, I found myself relaxing.

Jenny too seemed more comfortable and afterwards we took in another one of the excellent tribute acts that the cruise company seemed to be able to find. As we filed out she leaned over to me, "Do you want to go to that Cornucopia place or shall we just go back to the cabin?"

"What do you want to do?"

"I'd rather be just with you." I smiled at her and took her hand as we ambled slowly back to the cabin. When we opened the door I went to turn the lights on but Jenny stopped me, "No, leave them off."

"But I need a pee," I protested, "I can't go in the dark."

"OK, but just the bathroom lights." I went in and peed, but when I came back out again there was no sign of Jenny in the cabin. A little bemused I looked harder and then I saw her, out on the balcony, a dark shape just visible against the moonlit night. Something was reflecting a sparkle of green and I slid open the door to see better. She was leaning over the guardrail. Not dangerously so, just resting her arms on the rail. She was naked and her breasts were dangling attractively below her body.

My eyes roved down her back to her bum, and then I saw it, saw what had sparkled green, an emerald coloured butt plug, still showing brightly in the lights from the bathroom. I ran my had appreciatively over her bum, my fingers tracing lightly over the plug, feeling the contours between her cheeks.

"You approve?" she asked turning her head round to look at me. "I saw the way you looked at Helen and Sarah and thought I'd do the same."

"I do, have you had it in all evening?"

"Yes, that's why I've been a little tentative when sitting down, it feels great inside me, but you just have to be a bit careful."

"May I take a closer look?"

"Of course, that's why I'm wearing it." I went down onto my knees behind her, she had a nice bum and there was just enough light to make out her now bare pussy lips between her legs. The lug nestled deep in her, I could just about see the skin of her anus stretched slightly round it and a little tentatively I put my fingers to it and wiggled it a little.

"That feels nice," she murmured, rolling her hips slightly. I leaned forward and planted a kiss on it, then a series of kisses all round it, before sliding my lips down to her pussy and pressing them against her. "But that feels nicer." Encouraged I pushed my tongue out and licked the entire length of her pussy, tasting that muskiness as I parted her folds. I reached one hand between her legs and fondled her, sliding my fingertips over her clit, before using both hands to pull them apart.

I forced my tongue out as far as I could and rammed it into her, seeking her pussy opening and was rewarded with a soft groan and I could feel her pushing back against me. The butt plug was still glinting and on an impulse I wiggled it again eliciting another soft groan. Time to up the ante.

Standing up I stripped my clothes off, my cock springing up as I slid my boxers over it. The air was cool but my no means cold and I could see the moon reflecting on the water as the ship slipped almost silently along. I took my cock in my hand and rubbed it up and down her slit, I could feel the slickness of her juices and eased the tip against her opening.

"Yes," was the single word that came out of her mouth as I pushed steadily in, seeing the length of my prick disappearing into her warm wet tunnel. There was a soft sigh and I could feel her pushing back against me as we began to rock gently together. I recalled the night when she became very vocal and hoped she remembered where we were, suppose the neighbours had their balcony doors open? You weren't supposed to, it played havoc with the air conditioning, but there was something special about the night sea air. Perhaps they were doing the same as us, but then I thought that Jenny would be able to see and I giggled at the thought of the conversation they could have.

"Something amusing you?" she asked.

"No, just a silly thought,"

"Well concentrate on what you're doing, I want at least two orgasms before you cum."

"Your wish is my command." I reached round and cupped a breast, it felt heavy in my hand and I could feel her nipple hard in my hand, cold or aroused I wondered? Whichever Jenny seemed to like it and I could feel her pushing back, then her pussy muscles squeezing me. Our bodies were slapping together, making a very distinctive sound and again I wondered about our neighbours, we'd barely met them, just nodding as we occasionally bumped into them in the corridor.

I pulled my hand back and put a finger on the plug and wiggled it again, she paused for a second then resumed her squeezing and moving and I continued to agitate it in her bum. I wondered what would happen if I tried to take it out and pulled gently on it but it seemed reluctant to even move and I gave up and put my hands on her hips to steady ourselves.

Jenny began to moan and sigh, just softly as my cock plunged in and out of her pussy and I sensed rather than saw her hand creep between her legs and begin to rub her pussy, she must be getting close I thought and concentrated hard on sliding my prick as deep as I could inside her.

"That's it," she murmured, "just there like that." I could feel her hand begin to rub harder and faster, then with a sharp cry her pussy clamped down on me and she began to shiver and shake as her orgasm washed over her. I just held her tight, my cock buried deep inside her, not moving until the tremors died away and she began to slide back and forward again.

"One down, one to go," I commented.

"I don't mind it if you cum David, I was only joking, in fact that's what I want, to feel you cumming inside me. I don't mind where, in my pussy or my arse if you'd prefer."

"What? You want me to put it in your bum?" I asked, scarcely able to believe my ears again, my sister was proving to be a revelation.

"Why, don't you like that? I thought it was every man's dream." I'd certainly fantasised about it, but truth told I'd never actually done it. "Here let me get this out and then you can do it." Jenny reached round behind her and began to wiggle the plug about, I could see her arsehole stretching round the bulb then it was free and I could se her hole gaping.

"Quickly David, it'll close up again."

I pulled my cock out from her pussy, wondering if I was doing the right thing and then pushed it up against her back hole. Gently I eased forward and watched in amazement as it slowly disappeared from view. "There," announced Jenny, "just take it a bit easy for a while and it'll be fine." She felt incredibly tight round me and I slid back a little, just an inch or two then pushed forward again, feeling her rectum squeeze me tightly as I began to move softly in and out.

"That's starting to feel really nice now." It was a sentiment I had to agree with, I was being gripped as though by an all-enveloping glove, every inch of my cock being cosseted in warm velvet. I reached down with my hand and found her pussy, sliding my thumb inside and massaging her clit with two fingers. Jenny sighed in appreciation and I saw her hand grab onto her breast, squeezing the flesh hard as her thumb and fingers tugged down on her nipple, pulling it away from her.

"Cum when you want to David, cum inside me, that's the best bit, so warm and powerful." I could see her arsehole stretching round me, the ring of puckered flesh pulling in and out as my cock moved in and out of her. The sight, sensation and knowledge of just what I was doing was starting to get to me, I could feel my orgasm brewing inside me, starting deep down in my gut, my balls tightening as inexorably it grew and rose.

Half afraid of hurting her, I found myself pushing in harder and faster, my cock almost pulling completely out before plunging back into her most intimate depths. I could feel her moving with me, or rather against me, our flesh slapping together each time. My hand, still on her pussy was pushed away, to be replaced by Jenny's, her fingers beating a rapid tattoo on her clit. I grabbed hold of her hips and used the increased leverage to plunge as deep into her as I could, then I felt it, that surge starting so deep inside me, rushing to the surface and then I was cumming, my cock spewing forth in her arse, pulsing in those tight confines.

I heard Jenny gasp and then unbelievably her ring tightened even more round me and she began to wail, all thoughts of our neighbours forgotten as her head dropped onto her arms still resting on the guardrail. My balls ran dry and I collapsed onto her back, my hands encircling her to hold and support her breasts.

Gradually we calmed and I stood upright once more and very gently eased my cock out of her. It slid out slowly then popped right out and I could see her arsehole gaping once more before closing up. A globule of white escaped her and ran down beside her pussy lips before dropping to the ground, then Jenny stood up and turned to face me. "There, that wasn't so bad was it?" I just pulled her into a tight hug, my face buried in her neck as a whole gamut of thoughts and emotions ran through me.

"Sorry," she continued, "this bit gets a little messy, do you mind if I go and sort myself out?" We broke apart and she waddled a little unsteadily back in to the bathroom, one hand under her pussy, the other held to her backside. I watched her go, then picked up the green butt plug that was on the table and examined it, wondering what it would feel like inside me. Involuntarily I shivered at the thought and followed her in, closing the doors and the curtains behind me.

She wasn't long and then she came out, still naked, as I slipped past her and went in myself to clean myself up. When I came out she was in bed, covers drawn up to her shoulders and I slipped in beside her, pulling her once more into a tight hug. "That was truly a wonderful experience. Where did you learn to....?"

"Oh Frank and I used to indulge once in a while, it's not something you want to do every night, but on special occasions....." I snapped off the light and in each other's arms we went to sleep.

I woke in what seemed to have become our accustomed position, Jenny mostly on her front with me tucked in half against her. My cock was hard and pressing against her backside and automatically I rocked against her before last night's activities sprang into my head and I thought that perhaps that was not a good idea. She seemed sound asleep and rather than disturb her I decided to get up and sit on the balcony. I pulled back the curtains to discover we were actually in port, luckily we were facing away from the docks and I sat down in one of the chairs and took in the view over the far side of the harbour.

Memories of the previous night flooded back and I could still see the remnants of my cum on the balcony floor. Oh well, a bit more wouldn't hurt I decided and started to stroke myself, sliding my hand vigorously up and down my morning wood. I was just getting into it when the balcony door opened and there stood Jenny, naked. I looked up and saw the amused look in her eyes, "Couldn't wait for me then?"

"I thought you might be a little...."

"Sore?"

"Yes."

"Well actually I am, but it doesn't necessarily mean I don't want to partake. Here let me." She dropped to her knees between my legs and took hold of my cock and started to stroke it. It was so much nicer than my own hand and I sat back to bask in the sensations running through me. I watched as she bent her head forward and opened her mouth, then I was inside, being drawn right back until I could feel her throat, and then unbelievably even further, the head of my cock being squeezed by the tightness of the opening.

She gagged slightly and, I slipped back a little, then she tried again and I could feel myself being engulfed again. "Jenny, you don't have to...." My response was a choked gargling sound and a nodding of the head and then I could feel my orgasm rising swiftly inside me. Our eyes met, mine signalling a warning and then my cock was erupting, the first jet blasting deep in her, followed by another and another. I could see her throat working to swallow my cum, then clearly it became too much and I was jerked out of her mouth, the final few blasts decorating her face and hair with white globs. She sat back on her haunches and grinned, wiping her mouth with the back of her hand.

"Nice to see I haven't lost my touch completely."

It seemed only fair to let her shower first, and when we were both dressed we found our way to breakfast. "Do you mind if we stay on board today? I'm not sure I want to be wandering around in this heat. Perhaps we can just have a quiet day by the pool? Not the nude one, just one of the ordinary ones."

It suited me, the port held little attraction aside from a souk and it wasn't long before we were settled on a sun lounger. The upside was that it was less busy than usual and although I had fewer bare breasts to look at I was consoled by Jenny taking her top off, something that I was becoming rather familiar with. Initially she seemed to be in a little discomfort, but as the day wore on she seemed to get over it and was soon back to her normal self.

That night was to be our last on board and we decided to dine in style, heading afterwards for the dance floor. We danced close together, enjoying the sway of the music and the feeling of our bodies touching each other. I could feel the press of my cock against the inside of my trousers and knew that Jenny could feel it as well, as she was almost grinding against me. I was beginning to look forward to returning to our cabin when she whispered into my ear.

"Shall we be awfully daring and go in there tonight?" She nodded and following the line of her eyes I saw that she was indicating towards the doorway to Cornucopia.

"Are you sure?" I asked.

"I want to live my life without regrets, and if I don't do this, I'm sure I'll wish I had as soon as I'm home, so come on, give me some moral support, if not physical support." We made our way to the doors and which were opened to allow us entry. Inside was a small ante-chamber, where a number of plastic crates were stacked.

"Clothes in one of these please," asked the attendant politely, offering us a medium sized one. He turned his back respectfully and Jenny unzipped her dress and shimmied it off, before folding it neatly and placing it in the box. I followed suit and was standing there naked when she slipped her bra and panties off. The attendant turned back to us and offered us a box with a choice of green or red wristbands and I remembered what Helen and Sarah had told me. I took two red bands and handed one to Jenny. He opened another door and advised we could now go in.

The vista of a large room greeted us, it was gloomy, but around the edges there were pools of light, each one containing a piece of furniture such as a sofa or a bed and on each piece of furniture there were people, all naked, most engaged in some sort of sexual activity, some were merely watching, although pretty much all the men had erections that were being stroked either by them or their partners. There were couples engaged in sex, cocks ploughing into pussies, mouths round cocks or pressed up against pussies, everywhere the sounds and sights of one big orgy.

Jenny and I stood there, trying to take it in, I hadn't really known what to expect, but this exceeded my wildest dreams and I could feel my cock start to engorge with blood as it rose in front of me. Jenny's hand grabbed mine as we surveyed the room and started to walk further in. Right beside us was a woman with a man's cock in her mouth, she was bobbing rapidly up and down on it and she lifted her eyes as we walked past, before returning her full attentions to what she was doing. He had his hand buried between her legs, ramming several fingers into her pussy.

It was difficult to know where to look, we didn't want to appear voyeurs, but there were plenty of people just watching and we wandered around a little, taking in what was going on. A large knot of people were gathered round a bed and we found ourselves drawn to it. A woman was on all fours being ploughed from behind by a man with a large cock and in turn she was sucking the cock of a man in front of her. A second woman lay back on the bed rhythmically trusting several fingers into her pussy, her breasts wobbling on her chest. She looked up and I recognised Sarah, then I saw that the woman being fucked was Helen. Our eyes met and she released the man's cock, "David, Jenny, glad to see you decided to join us. Do you want to take over from Mike or Paul, I'm sure they'll be happy to look after your sister for a bit."

I recognised the two men now, who nodded at me as if we were just passing on the street. I could sense that Jenny wasn't too enamoured with the idea and responded that we wanted to look around a bit more but would definitely catch up with them later. I led Jenny away as she gripped my hand fiercely. "You didn't want to did you?" she asked me, "I wouldn't have minded," she continued but I could see she was only being gracious.

"No, let's go and find somewhere to sit and take all this in." We found an empty small sofa and sat down, side by side as we continued to take in all that was going on round us. "Are you happy to stay or do you want to leave?" I asked sensing again her lack of comfort. Our legs were touching and I could feel Jenny's pressing against me then a small hand encircled my erect cock and began to stroke it. Our eyes met and she smiled at me.

"No, I'm happy to stay as long as it's just us. For the moment anyway." She added as her hand slid up and down my shaft. I leaned in and kissed her as my hand lifted to her breast and cupped it, my fingers brushing lightly over her nipple. "That's nice," she murmured, shifting round a little more towards me and I saw her other hand drop between her legs and begin to press into herself.

Our lips met again, this time her tongue pushed inside my mouth, beginning to dance around inside, teasing my tongue. She shifted again, her hand releasing my cock, then she was astride me, knees planted firmly either side of my thighs as her hand found my cock again. In his position I was able to access both breasts, one in each hand and I fondled them, squeezing and moulding that soft flesh, feeling her nipples become harder.

I bent my head and sucked one gently into my mouth, running my tongue round and round the hard nub drawing it deeper into my mouth. I sensed her rising up then the tip of my cock was being rubbed up and down what felt like a very slick slit before being engulfed in a warm wet sheath as she lowered herself down again until our bodies were once more against each other.

"Are you sure?" I asked, receiving a knowing smile in return as she slowly began to grind against me. I could feel my cock being squeezed by her pussy, the sensation sending waves of pleasure coursing through my body. I returned my attention to her breasts, kissing and sucking her nipples as my hands fondled and caressed her. I realised I had lost awareness of the room around me, all my senses concentrated on Jenny and that wonderful feeling emanating from between my legs.

That was until the sofa dipped and I looked round to see a woman sitting beside me, as naked as the rest of the room. She smiled at me, "You don't mind if we come and watch do you, you looked so loving together."

"No, of course not," Jenny replied to my surprise, her body slowly bobbing up and down on my cock without missing a beat. I looked back and saw a man sitting the other side, an erect cock sticking up from his lap, one hand wrapped round it, slowly stroking himself.

We continued as before, my cock slipping easily in and out of Jenny's pussy as our new friends just sat and watched, him playing with his cock and her lightly running her fingers over her pussy and breasts. I could feel Jenny starting to become more intense, she was beginning to force the pace a little and I went along with it, dropping my hands to her bum, clasping the globes to help and guide her. Our friends seemed to pick up on this, first he moved so he was kneeling upright on the seat, his body and especially his cock much closer to Jenny now as his hand began to stroke more rapidly. Then she adopted a similar pose and I could see her pussy between her legs now, lips parted and a sheen of moisture glistening on them in the spotlights beating down on us.

I wondered how Jenny would react, she looked intently at his hand, beating away, then to my amazement she reached one hand out and took over rubbing him. I could see surprise register in his face and he looked over at his partner who just smiled before reaching out a hand to fondle Jenny's breast. I was in danger of feeling left out and determined to make the most of the opportunity reached between her legs and ran my fingers along her pussy.

I was right, she was very wet and I could feel the slickness in her slit as my fingers gently parted her folds and found her core. One finger found her pussy and I pushed it in followed by a second as my thumb pressed against her clit. I could feel her body rocking against the pressure of my hand as my fingers sawed in and out of her tunnel.

It seemed to go on forever, but couldn't have been long, then I heard a gasp from him and looked over to see his face screwed up tight. Jenny's hand became a blur on his cock and then his body went rigid and I saw a spurt of cum erupt from the end of his cock, spattering over Jenny's breasts, swiftly followed by a second or a third. Momentarily she stopped moving then resumed with passion, her body slamming down on mine, her pussy gripping me tight.

The woman beside me leaned forward and started to lick his cum from Jenny's breasts, sucking her nipples into her mouth, then lapping the white goo from her chest. Jenny let loose a cry and I felt her pussy tighten round me and her body began to shudder. I pulled my fingers from the woman's pussy and grabbed Jenny's backside, ramming my cock hard up into her, then I felt a surge from within me and I was cumming, powerful jets of cum spurting deep into her pussy. My female companion collapsed back down onto the sofa and legs wide apart rubbed furiously at her pussy until her body too was wracked with shudders.

Jenny collapsed forward onto me and suddenly all was still, just the sound of ragged panting from all four of us. Both of them knelt up and put their arms round us and for a brief moment we remained like that, joined in a loving embrace. Then with a murmured "Thank you," they stood and walked away leaving just the two of us.

"Well that was unexpected," I commented.

"Yes," agreed jenny, "unexpected but very definitely not unwelcome. Shall we go now, I just want to be in our bed together, just the two of us." We stood and with a last lingering look around left. We dressed quickly and made our way back to our cabin, falling into bed together in each other's arms, remaining that way until we woke, the light bright behind the curtains. I opened my eyes to see Jenny looking at me.

"Good, you're awake, we've just got time."

"For what?"

"This." She rolled over on top of me and before I realised it I was buried in her once more, her body rocking to and fro driving my cock deep into her pussy. It wasn't long before we were both cumming, falling apart back onto the bed. When I had recovered sufficiently I got up and opened the curtains to see we were in port and I realised it was disembarkation day and that our adventure was over.

Disembarkation was as efficient as it could be and we were loaded onto coaches to be whisked off to the airport and its interminable procedures, but finally we were sitting at the departure gate waiting to board. Jenny nudged me, "Do you see who that is?" I looked up to meet the gaze of another couple, who smiled back and I realised it was our new friends. With their clothes on they looked....'normal' and I began to realise what a strange trip we had been on.

The flight was mercifully short and we dozed a bit before landing. It was when we were in the baggage hall waiting for our cases when someone tapped me on the shoulder. It was the man from the night before, offering me a small piece of paper, I glanced down at it, on it was telephone number, "Just in case you wanted to....." he suggested before turning and walking away. I tucked it in my wallet, just in case.

I drove us back to Jenny's house and pulled up outside. She turned to me and put her hand on my inner thigh, "Would you like to come in for a while?" she asked suggestively.

I admit I was sorely tempted, but I had anticipated the situation and had already made my mind up.

"I'd love to Jenny, but I think it best that what goes on tour, stays on tour don't you?"

She looked wistfully at me, "I suppose so but I did really enjoy our time together."

"Don't get me wrong Jenny so did I, but this has to be for the best."

"Yes, you're right, but if I were to book another, similar style cruise later in the year would you be interested in coming with me?"

"Jenny, wild horses wouldn't keep me away."
