Just Another Day

Tom put the last of his Sunday lunch onto his fork and pushed it into his mouth, savouring the taste, his mother was a good cook, but her Sunday roasts were legendary. Clearly the rest of the family thought so as well, his father and sister concentrating in silence on the last of their meal.

"Mum, that was absolutely delicious as usual," Tom complimented her, a sentiment seconded by the others.

He looked round the table, his father, now in his mid-forties but still slim and fit, his mother, the same age as her husband, and Tom took a second to look at her, he thought she was beautiful and she still had a body that all his friends drooled over, a MILF they called her, and whilst he basked in their admiration for her he didn't like that term. Of course like every teenaged boy he had fantasies about having sex with her, but 'Mother I'd like to Fuck' sounded so crude.

He'd never really got a good look at her body naked, he'd glimpsed her breasts occasionally and once he'd seen her fully nude but only from the back and he still masturbated over that memory, something he did at least once a day, more now he had finished school and was home for the holidays. He felt particularly grown up, he had turned eighteen six months earlier and had now done all his exams and was waiting for the results to confirm his attendance at university. He'd even lost his virginity some months ago at a party, it was all over far too quickly, but he was looking forward to doing it again, although at the moment prospective partners were looking a little thin on the ground.

The final member of the family was his twin sister Kathy, he'd seen pictures of his Mum at that age and they were uncannily alike. She had the typical body of an eighteen year old, lithe, firm and with surprisingly large boobs, not that he'd ever seen them, she was too careful for that, all he'd got were glimpses down her blouse when she forgot and bent too far forward. He was fairly sure she was a virgin still, she didn't have a regular boyfriend and she wasn't the type for casual sex, well he didn't think so anyway. He wondered if she masturbated, all his friends said all girls did it, even married adults, but if you could have sex why bother with your hand, so perhaps they were wrong.

He was looking forward to the afternoon when he could repair to his room and have a good wank, he'd discovered a website with erotic stories and he found they could be more arousing than stereotypical visual porn. He'd got some favourite authors already and was slowly working his way through their works.

In fact he could feel his cock starting to strain at his trousers already in anticipation and he gave it a subtle squeeze under the table as he recalled some of the stories. His reverie was interrupted by the sound of his father's voice and he quickly tuned back in.

"We've got something we want to talk to you about, something that will affect you both."

Kathy felt a cold hand grab her insides and before she could stop herself the words burst out of her mouth, "You're not getting divorced are you?" Her best friend Sarah's parents had recently split up and she had seen the anguish that had caused. Her eyes met Tom's and she saw the same thought had gone through him. As twins they had a special bond, they weren't particularly close in a physical sense, but somehow she always felt what he was thinking, a shared empathy.

"No of course not, whatever gave you that notion?" her mother replied quickly, reaching out and clasping her husband's hand, "In fact if you must know we've never been happier."

"You're not pregnant?" Both her parents laughed, and from the way they looked at each other Kathy knew they'd had sex recently. Not that she knew an awful lot about that sort of thing, of course she knew where babies came from, but she'd never even seen a man's penis, soft or erect, but she'd heard enough noises coming from their bedroom to know they had a healthy sex life, plenty of moans and groans permeating through their shared wall. In fact, now she thought about it last night had been particularly stimulating.

She'd lain in her bed and her hand had toyed with her pussy through her panties, initially just stroking her pussy and clit through the soft material, but the temptation had been too much and her fingers had soon found their way inside and she'd frigged herself with considerable enthusiasm until her orgasm had exploded and she'd writhed and shuddered in her bed, hoping she hadn't cried out.

Only her best friend Sarah knew she did that, they shared all their secrets and desires. Sarah she knew wasn't a virgin, she seemed to have a much more casual attitude to sex, "Something that feels that good can't be bad for you surely." was her oft quoted motto. She sometimes wished she could be like that, but somehow the opportunity had never arisen and deep down she knew she couldn't be like that with just anyone.

"Nor that." their mother replied, "It's no big thing really, or we hope it won't be. You remember we went on holiday to the Canaries earlier in the year," both Tom and Kathy nodded, they'd been pleased that their parents had trusted them sufficiently to leave them to fend for themselves for ten days, "well we spent quite a bit of time on clothing optional beaches and we found we really enjoyed the feeling of freedom it gave us."

"What?" Kathy shrieked, "You ran around in public with no clothes on? Ugh! Gross!"

"It wasn't at all like that Kathy, there were all sorts of people there, of all ages, even some families and really no-one took any notice. In fact after a while it felt strange having clothes on at all."

"Doesn't the sand get in everywhere? No! TMI, I don't want to know. But what has that got to do with us?" Their parents looked at each other, then their mother continued, "Well, we'd like to repeat that experience, only this time at home, and we wondered that now you are both adults, if you'd like to share that with us?"

There was silence round the table as Tom and Kathy tried to take in what was being said. It was Kathy who reacted first, "You mean become nudists?"

"I don't think we'd want to go that far, but have you heard of National Nude Day?"

Tom had been silent throughout the exchange, his mind whirling, thoughts of seeing his mother and sister naked running through his head at a hundred miles an hour. "Isn't that something they do in America, everyone goes around naked all day and they all have sex with each other?" He'd read lots of stories about it, the website had an annual competition for stories with that topic and he'd actually enjoyed reading many of them.

"No, it's not about sex at all, it's about enjoying the freedom that being naked offers in a private setting, in our own home within our own family."

"But won't Dad and Tom get...." Kathy couldn't bring herself to say it.

"Erections? Yes, almost certainly," answered their father, "but they are natural responses and I'm sure we can be discreet about them and if necessary deal with them." A vision of her father and brother with huge erect penises sticking out in front of them went through Kathy's mind and she suddenly felt a little twinge in her pussy and a trickle started inside her.

There was silence for a while as both Kathy and Tom absorbed the impact of what they were being asked to do, well at least consider. Tom couldn't help but feel a surge of excitement, the prospect of seeing his mother and sister naked, not only seeing but spending a whole day with them seemingly too good to be true. But at the back of his mind was a nagging fear, what if he couldn't control his cock, the odd erection might me acceptable but he could hardly go round with one all day, and there was a limit to how many wanks he could have without his cock getting sore, he'd experienced that once before and had to abstain for several days afterwards and had no wish to repeat the experience.

"When would all this take place?" Kathy asked.

Their parents shared another knowing look, "Tomorrow." replied their father evenly.

"Tomorrow?" shrieked Kathy.

"Yes," continued their mother, "I've got the day off and your father will be working from home." A vision of his father sitting at his laptop with a dress shirt on and his cock sticking up between the shirt tails ran through Tom's mind and he smiled.

"I take that as a yes then Tom?" asked his mother. Anxious not to be asked why else he was smiling Tom nodded and all eyes turned to Kathy.

"No, no way." protested Kathy, "There's no way I'm getting naked in front of Dad and him." She nodded towards her brother.

"Well just think about it," suggested her mother, "no-one's going to make you do it, you can either go out for the day or stay clothed. It's just another day after all." They got up from the table and everyone pitched in to do the washing up, most went into the dishwasher so it didn't take long. Kathy disappeared immediately and once Tom had looked at the football choice on TV he too went up to his room. Perhaps he'd read a couple of stories and who knows, even have a wank thinking about the next day.

Predictably he searched for Nude Day stories and was starting to get engrossed in one, squeezing his cock through his trousers when there was a knock on the door and it opened immediately. Quickly he moved his hand away and closed his iPad, looking up to see his sister at the doorway. She closed the door and came to sit on his bed beside him.

"You're not really going to do it are you?"

"Of course," he replied, full of bravado, "it's no big deal, as Mum said, it's just another day."

Kathy didn't seem so sure, her eyes were downcast and her fingers fiddled nervously with the bed covers. "I sort of want to do it, but I've never been naked in front of anyone before, not even Sarah or Mum." Tom looked at her surprised, he'd been to an all boys' school and it was normal for the boys to shower together after sport, perhaps girls' schools were different he surmised.

"Well you could start now and take your clothes off in front of me," he suggested, his tongue firmly in his cheek.

"You think that would help?" asked Kathy quietly, "You wouldn't mind? Both of us I mean?" Tom looked at his sister, amazed that his quip had been taken literally.

"Well it might. We could do it in stages, I'd go first if you like."

Kathy looked at him and softly nodded and Tom's stomach lurched at the prospect of finally seeing his sister naked. He put his iPad down and swiftly pulled his tee shirt over his head, tossing it flamboyantly to one side. "See, easy."

Somewhat more hesitantly Kathy crossed her arms and grasped the hem of her tee shirt and pulled it up and over her head. Tom almost gasped as her bra encased breasts came into view. Her nipples weren't visible, but he could see the soft bulge of her breast above each cup and he mentally licked his lips. For a second she sat there and Tom could see the hesitation running through her, then a resolute expression came over her face and she reached behind her and unsnapped her bra.

At first nothing happened, her breasts didn't move and the bra stuck to them like glue, then she shrugged her shoulders and it fell away. Tom almost gasped, they were full and firm, tear drop shaped with delectable round brown nipples at the ends and his eyes went wide at the sight before him. He could feel his cock straining inside his trousers, rarely had he been so hard so quickly.

Kathy mistook his silence for disapproval, "You don't like them?" she asked.

"No, I mean yes. They're wonderful Kathy." He longed to reach out and cup one, to feel their obvious firmness and it was with some considerable difficulty that he restrained himself.

"Now it's your turn again," she said, "I want to see your....." she struggled over the word, ".... cock." Tom leaned back and even he could see the huge bulge in his trousers. He undid the buttons and slid down the zip and swiftly pushed his trousers and underwear right down past his knees. His cock sprang up, he wasn't huge, not if all the magazines were right, but he'd measured it several times and knew he was above average at seven inches. He wasn't circumcised but the glans was protruding from the end, purple and bulbous.

Kathy let loose a stifled scream and covered her mouth with her hand. She'd been prepared to see something large, but this looked huge and somehow threatening. What shocked her almost as much was the way her body's autonomous systems reacted, a huge gush of fluid surging down her pussy, almost frightening her with its intensity. Suddenly she wanted to get out of there, to be away from that monster whose main aim was to get inside her pussy, a pussy that felt tight round one finger, all she'd ever dared put inside her and that thing had to be at least five times the size.

She stood up abruptly, her breasts bouncing on her chest and grabbing her bra and tee shirt turned tail and ran out of his room, leaving the door wide open. Tom just sat for a second, wondering just what had happened, then he realised how exposed he was and lurched over to the door to close it. He sat back on his bed and automatically his hand went round his cock, stroking it up and down, his mind reliving the sight of his sister's breasts and the way they'd bounced when she stood up.

Faster and faster his hand flew, then he felt his orgasm rising swiftly in him and he grabbed a handful of the tissues his mother always left by his bedside, to catch the cum spurting from the end. Sated he rolled back onto the bed, his cock still in his hand as he let his body return to normal. How was he going to face Kathy now though? She'd been upset over something, he'd done nothing but he didn't like to think of her in that frame of mind and he quickly put his clothes back on and went and knocked softly at her door.

After what seemed like a long time he heard a quiet "Come in." and he eased open the door and peered in. She was fully dressed and sitting on her bed, a wad of tissues pressed to her eyes. "I'm sorry," she apologised, "it was all just too much." There was a further outbreak of tears and Tom went and sat down beside her, putting an arm round her.

"It's all right, you don't have to do it, you could go and see Sarah for the day."

"No, I want to do it and I'm going to. Let me get myself straight and I'll be down." Tom gave her a tight squeeze and left her to repair the damage. His parents were in the lounge, his father watching TV and his mother reading. They looked up as he went in and sat down.

"Everything all right?" his mother asked, "We thought we heard an upset, you haven't been fighting with your sister have you?"

"No quite the opposite actually." They left it at that and he settled down to watch a rather uninspiring football match. Towards the end Kathy appeared and stood in front of them, "I've decided I'll do it," she announced, "and I'm determined to enjoy it."

"That's wonderful!" replied their mother, "Let's have a family hug to seal the deal." They all stood and put their arms round each other, Kathy and Tom getting kisses from their mother. It was at that moment that one team scored and they all missed what turned out to be the only goal of the game.

Nothing more was said about the next day and they all went to bed at a reasonable time, so it was relatively early for Tom when he awoke with a raging hard-on as usual. Automatically his hand found his cock and he began to stroke it, his mind opening the wank bank for some suitable material. Like a bullet to the brain up flashed his sister's breasts and then he remembered what today was, National Nude Day and he was going to see his mother and sister stark naked. The thought sent a tremor through his body and his hand gripped his cock nice and firmly.

Then his mother's words came back to him, "It's not about sex at all." Well a wank wasn't sex was it? It was probably the closest he was going to get for a while, and certainly today, and he suddenly felt as though he was tarnishing what his mother wanted from the day. Reluctantly he released his cock and tried to think of something else and eventually he was pleased that his erection began to subside, not completely but enough that it wouldn't be sticking out at right angles from his body.

He tuned his ears outward, listening for sounds of anyone up and about and heard the chink and rattle of crockery and cutlery being laid for breakfast. His mother at least was up and despite his earlier resolution his cock twitched at the thought of her downstairs naked.

Before he knew what he was doing he had rolled out of bed and was automatically grabbing his dressing gown. What was the etiquette he wondered? Should he just saunter downstairs naked, or should he put the dressing gown on and then disrobe when he was there. The whole point was to forgo clothes all day he thought, so it was stark bollock naked then. He opened the door and found the landing empty, thank heavens, his sister's door was shut but his parents' was wide open, not that they usually shut it completely anyway, but he could see that the bed was pulled back and empty. It felt strange walking down the stairs with no clothes on, his cock swinging between his legs and he nearly chickened out, but he could hear the sound of voices and steeled himself to continue.

Across the hallway to the kitchen where he paused at the door. His father was sitting at the table, his top half was bare but he couldn't see any more. He was looking at his phone and Tom remembered he was supposed to be working from home. He took one pace inside and then he saw his mother, she was standing at the sink, her back to him and he took in her body. He couldn't see her breasts, but her back tapered into a slim waist then her hips flared out again into what looked very much like a neatly pert bum, split by a vertical crease.

He wasn't conscious he'd made any noise but they both looked round at him, a broad smile breaking out on his mother's face as she took in his nakedness. "Well done Tom," she congratulated him, turning as she took a step towards him. He tried desperately to focus on her face but all his eyes could see were her breasts, so similar to Kathy's but a little larger and saggier, but what really caught his attention were her nipples. They were much bigger than Kathy's, broad and dark with a very prominent nub in the centre.

Then his eyes dropped further and lit on the triangle of black curly hair between her legs and just below it he could make out a pair of prominent pussy lips. His mouth dropped but unfortunately his cock reacted in the opposite way and rose swiftly into a full erection. "Mum," he croaked, his hands dropping to attempt to conceal his rampant prick as his mother closed on him and wrapped him in a hug, her breasts pressing against his chest and her lower body colliding with his cock as he attempted to turn away from her.

"Sorry," he apologised, trying to wriggle away from her.

"Oh don't be silly, it's not the first one I've seen, and not even the first one this morning, your Dad's being trying to do something with his since we got up." Tom looked over at his father who was rising from his chair, and sure enough he too had a stiff cock.

"If it gets too much son, just go and deal with it," he offered in a fatherly manner as he held out his hand for Tom to shake. It seemed an odd thing to do but Tom took it as his mother released him and turned back to the sink. "Sit down Tom, it's less obtrusive that way," continued his father, regaining his own seat and looking back to his phone.

His mother put a mug of tea in front of him and he looked up to thank her, realising that in this position he was so much closer to her pussy. What should he call it he wondered? Vagina was so cold and biological, he didn't like the word cunt, MILF's had cunts and his mother was definitely not a MILF. He'd heard the terms veejayjay and hoohah, but they seemed so frivolous.

His musings were interrupted by the words, "Mum, Dad," coming from the doorway. Everyone looked up and there was Kathy, without a stitch of clothes on. She was steadfastly holding her hands at her sides, but Tom could see she was desperately trying not to cover herself up. He'd seen her breasts before of course, but they looked even more spectacular than yesterday.

He looked down and saw that she was totally bald between her legs, not a hair in sight and her pussy was completely visible, a pair of very neat lips on display. There, he'd used the term pussy, that was what it had to be. His mother went over to her and pulled her into a tight hug, no awkward bits to get in the way there thought Tom as he watched their breasts squash together. They broke apart, Tom could swear he saw tears in his mother's eyes, and Tom saw his father rise from his chair as he had for Tom. Kathy looked own at his erect penis and Tom held his breath hoping she didn't repeat her actions of the previous day. To his relief she barely paid any attention to it as she closed in for a hug which they managed without any lower body contact.

"Brother," she greeted him, coming round the table to hug his upper body, briefly he felt the press of a breast on his shoulder and then she was sitting calmly down in the empty chair and all he could see were her breasts as though that was not enough.

In fact Kathy wasn't at all calm, inside her stomach was churning and she was almost trembling. She'd woken up that morning and as usual her hands dropped to her inner thighs and she lightly ran them up and over her panties, pausing just long enough to gently stroke her pussy on the way up. Then over her breasts, cupping them and brushing her nipples before stretching her arms up over her head. She normally slept in just a pair of panties in the summer, PJs were too hot.

She could hear voices and remembered her father was working from home and then her brain recalled why. A shock ran through her and she wondered why on earth she had agreed to join in with what now seemed a wholly stupid idea. She knew she couldn't back out though, although her parents wouldn't say anything, and although her brother had been really, really kind the day before, he would still tease her about it for years to come. No, she was going to have to face it.

She rolled out of bed and slipped her knickers off, examining the gusset as she did so, she sometimes had a leaky pussy and she didn't want any obvious signs for anyone to see. She recalled the way her body had reacted when she'd first seen Tom's erect penis, that rush of juice down her, it had pretty much soaked her panties which was partly why she'd had to rush out and she dreaded the same thing happening today.

She went into the bathroom and peed, carefully drying her pussy, then washed her hands and started down the stairs. She could hear her parents' voices and her brother's, he seemed to be apologising for something and she steeled herself to face them. Twice she nearly turned back but before she knew it she was standing in the doorway greeting them.

They all looked up at her, and her mother came straight over and hugged her. She was surprised her mother hadn't shaved between her legs, she thought everyone did that these days, but then perhaps she and her Dad... no she didn't want to go there. Then her Dad was beside her, his penis sticking straight out and for a second she found herself comparing it to her brother's. It didn't look quite so large and threatening somehow, she thought, thrusting those thoughts away.

He brother remained seated and she didn't have to look at him, although she could just see the tip sticking up. That wasn't as bad as she'd thought it was going to be as she sat down. Her breasts were still exposed, but at least no-one was looking at her pussy, and at worst she'd just leave a little damp patch on the chair.

She was amazed how normal the chatter was over breakfast, then her mother announced she was going for a shower and her father said he'd better start work. That left Tom and Kathy to clear up, something they often did together, but not dressed or rather undressed as they currently were. Kathy stood up and carried a few dishes over to the dishwasher, then bent forward and opened it. Tom couldn't help but look as her breasts fell forward, then from behind he caught the merest flash of pussy. His cock that had started to behave, twitched, but fortunately remained at half-mast as he got up to help her. Although both were very cognizant of the other's proximity they carefully managed to avoid touching each other and soon everything was as their mother would like to find it.

"I'm going for a shower now," announced Kathy. She and Tom shared a bathroom, their parents had an en-suite in their room.

"OK, no problem, I'll read the paper for a bit." Tom had a digital subscription for a quality paper, as a student he got a sizeable discount and he tried to read most of it most days. He settled in the lounge, he could hear his father beavering away in the adjoining dining room, the sound travelling through the open connecting door. As he read he felt his cock slowly deflating until it was once more at its normal flaccid size, perhaps today wasn't going to be as bad as he feared.

In his subconscious he was aware of the sound of showers going on and off, his mother and sister he assumed, the thought barely registering as his eyes ran over the digital newsprint. Similarly he heard his father's voice, clearly on the phone, it sounded like a long call judging from the tenor and tone of his voice.

Another voice intruded, his mother's, "I've had a bit of a trim Richard, what do you think? Oh sorry, didn't realise you were on the phone." She appeared in the doorway and Tom looked up. "What do you think Tom?" She sauntered over to him and stood a couple of feet from his knees, then flexed her knees slightly and thrust her pelvis forward. Tom realised what was different, gone was the tangle of black curly hair, replaced with... absolutely nothing.

From his slightly lower position he could see along the entire length of her slit, darker crinkled inner lips protruding slightly and not a hair in sight. She put her fingers either side of her pussy and pulled the skin taut and a hint of pinkness appeared. Tom's cock reacted immediately, 0-90 degrees in an instant, the glans once more protruding darkly from his foreskin.

Suddenly she seemed to realise what she'd done, immediately apologising, "Sorry Tom, I just didn't think, I was so pleased with my new look, Kathy's looked so nice and.... I'm gabbling aren't I?" Her eyes widened as she took in his cock, "Did I do that to you? I'm sorry, I.. I.. I."

Tom took pity on her, "Don't worry Mum, I'll go and have my shower now, you go and show Dad, he's finished his call now." He nodded towards the doorway where his father was standing, his cock hanging limply.

"Did you want something?"

Tom stood and walked awkwardly towards the stairs, then holding his erection in his hand started to climb. As his head broke clear of the top he saw that the bathroom door was still firmly shut and Kathy's door open so clearly she hadn't finished yet. She was notorious for bathroom blocking and he wasn't surprised. Oh well, back to the paper.

Down he went, the lounge was empty and he resumed his seat and was about to pick up his iPad again when he saw movement in the dining room. His father was sitting down, his mother standing before him and he was peering intently at her pussy, then he leaned forward and planted a kiss on it before sitting back a little and stroking the back of his fingers across her mons. Tom watched entranced as he changed his grip and cupped her pussy, sliding his fingers back and forth between her legs, then it looked very much as though he was pushing several fingers into her.

Tom had to stifle a gasp as he pushed himself back in the chair, trying to make himself as invisible as possible. His mother had her head back slightly and her eyes shut as her body rocked to and fro gently before she opened them again and leaned forward. A hand reached down and then began to pump up and down, mimicking his own arm action Tom realised, as those familiar pleasurable sensations started to course through him.

There was a momentary flash of panic as they both looked his way, but his mother's rhythm never faltered and they both looked back at each other. Tom wondered where this was all going to end, were they going to have sex, there in the dining room in front of him? It seemed not as his mother dropped to her knees, between his legs, then the steady movement of her arm was replaced by a gentle bobbing of her head.

Blowjobs were real then, Tom realised, everyone talked about them, but he had a naturally cynical view that no-one really did them, who would want a cock in their mouth he'd thought? What would it feel like, his imagination fuelled by the feelings emanating from his cock tried to picture it, and his head fell back on the headrest.

"Bathroom's free," came a shout from upstairs and they both looked up again, but seemed not to see him. When they turned back he gingerly got up and slunk out of the room, quietly climbing the stairs and going into the now empty bathroom. He turned the shower back on and stepped under it, his hand pumping his cock for all he was worth.

Everything from the morning was flooding through his mind, now heedless of his previous resolution, the sight of his mother and sister naked, hairy pussies, bald pussies, bouncing breasts, big nipples small nipples, then he exploded, his cock spurting cum all over the shower screen. Huge globules of white goo spattering against the glass before the water slowly washed them away. He rubbed until it hurt, then leaned against the shower wall, his heart thudding in his chest, gulping in precious oxygen until he felt calm again.

Finished showering, he dried himself on a towel then remembered he didn't need to dress again, perhaps there was something in this nudity lark he thought as he tucked the towel back in the airing cupboard to dry. With a bit more of a swagger than he'd exhibited first thing, he went back downstairs into the lounge. His father was sitting working, he was relieved to see, then as he sat back down to finish the paper he heard the sound of the vacuum cleaner start. Slowly the sound got closer and then his mother appeared, her arm running the device back and forth, much like she had with his father's cock Tom thought impishly.

He sat and observed her through half lidded eyes, her breasts were wobbling most attractively and he was pleased he'd just had a wank or else he would have been hard again. She seemed unconcerned about her nakedness as she switched off the machine. "Feeling better?" she asked, her eyes dropping briefly to his waist.

"Much, thanks Mum." He wondered if she'd guessed about his orgasm or whether she was just referring to his shower.

"Good. It's always good to relieve the tension, we all need to do it now and again. Your Dad feels better as well." Well that settled what she was talking about, and perhaps even hinted that she knew he'd watched. She turned the vacuum back on and resumed her housework. Abruptly the machine went off again, "Where's your sister?"

"Haven't seen her since she went for her shower Mum."

"I expect she's hiding in her room, she shouldn't do that, it's unsociable. I'll root her out when I go up." On went the machine again and her breasts resumed their mesmeric dance.

It wasn't long before his Mum re-appeared, "She was on the phone, probably to Sarah, those girls spend an unhealthy amount of time on the phone or peering at a screen. She says she'll be down in a minute or two." She produced a duster and began to run it around all the surfaces, humming quietly to herself.

Kathy appeared and approached her mother, "Mum, can Sarah come round after lunch."

"Today? Does she know what we're doing today? Is she happy with that?"

"Yes she's quite happy to join in, she says nudity doesn't bother her, her parents took her to lots of nude beaches on holiday." Actually what she'd said was that she'd seen more cocks and cunts than Kathy had had hot dinners and another few wouldn't make any difference.

"Well as long as she knows what she's getting into I suppose it will be OK." She moved her dusting to another room and left the two of them alone.

Tom's cock had twitched at what he'd heard, he'd known Sarah for as long as he could remember, the three of them had grown up together, and although he hadn't seen much of her in recent years, he knew that she had a lovely body and if she was going to expose it for him then he certainly wasn't going to object.

"What are you doing Tom?"

"Just started the crossword."

"Want any help?"

"Sure." He wasn't quite prepared for Kathy to plonk herself down on the sofa beside him, her legs tucked under her and her body pressed close up against him. Not only could he see her breasts right next to him, he could feel their press against his arm. It was very enjoyable, but didn't aid his concentration as his eyes skimmed across the clues without actually settling on the words.

"Tom, can I ask you a question?"

"Of course, anything."

"What do men call their penis?"

Tom was a little shocked by the question, but she seemed serious about it and he thought back to his dilemma about vaginas. "There are lots of names, dick, todger, John Thomas, willy, but I suppose cock is the most used, although that's not really very polite."

"A bit like cunt you mean?"

"No it's nowhere near as rude as that, but it's not a word I'd use to Mum. Why do you ask?"

"Oh, it's just something that Sarah said. You don't mind her coming round do you? She'll see your cock, but then you'll get to see her cunt so it will be fair."

Tom looked down to see that his sister was grinning back up at him, clearly taking the piss and without thinking he reached round to tickle her, just as he would have done had she been fully clothed. Scarcely had his fingers touched her when he realised his error, but not before she'd tried to wriggle away and he found her breasts in his hands. Hastily he pulled them back, apologising profusely.

"Don't worry, Tom, I quite like the feel of them in your hands, makes a change to have someone else touch them." Tom didn't quite know to whom she was referring, was it her or was someone else in the habit of touching them? He decided not to pursue the matter and together they set about the crossword.

The morning came and went and Tom was pleased that he seemed to be getting things under control, 'things' being his cock. Despite the continued presence of two pairs of breasts and the occasional appearance of a pussy he found that his erections didn't appear quite so often and moreover, they went away fairly quickly. He briefly worried that he was becoming so inured to the sights that he'd never be able to perform again, but then something would happen, e. g. his mother bending over right in front of him and presenting him with an unparalleled view of her arsehole and gaping pussy, which prompted an immediate reaction.

Just as lunch was being prepared the doorbell rang and everyone looked at each other in horror, each wondering who was going to face the postman or courier, when Kathy announced that it was Sarah arriving a bit early. She bounded to the door, her breasts bouncing nicely and threw it open.

"My God, you're really doing it!" came a shriek from the hallway and then Sarah appeared, her eyes wide open, head turning rapidly from side to side as she took in their nudity. "Hello Mrs Harrison," she greeted their mother and went to hug her as usual but pulled back at the last minute, contenting herself with an arm round the shoulders and an air kiss.

"Hello Tom," She turned to him and he saw her eyes going up and down his body and then coming to rest on his fortunately still flaccid cock. "I thought you'd be...." Words seemed to fail her at the last minute.

"He normally is," finished Kathy for her, "but for the time being it seems to be having a rest."

"Hi, Mr Harrison," Sarah called out receiving a cheery greeting in response, although their Dad didn't come into the kitchen.

"You don't have to take your clothes off if you don't want to Sarah," offered their mother kindly, "it's not everyone's cup of tea."

"Oh don't worry about me," replied Sarah breezily, "I'm used to it. Shall I get undressed down here or upstairs?"

"Come on, we'll go up to my room," declared Kathy and taking Sarah by the hand led her away. She shut her bedroom door behind her, then thought that was a pointless exercise but left it shut anyway.

"I've never seen you naked," observed Sarah, "well not since you grew these," she reached out and gently caressed Kathy's breasts, a gesture that sent a little shiver through Kathy. "You've got a lovely body though and I see you've shaved your pubes, so much nicer don't you think." Again she ran her fingers lightly over Kathy's pussy. "I've been busting to get round here and join you."

With that she pulled her tee shirt over her head revealing a pair of smallish but pert breasts in a pale pink bra. She reached behind her and unsnapped it, then with a flourish pulled it away from her body. Her breasts barely moved, they were smaller than Kathy's, slightly up-turned with long pointy nipples. "They're not as big as yours, and I hate these," she rolled her nipples between her thumbs and fingers, "but they're really sensitive and make me so wet when I play with them. Sometimes I can even cum from just that."

She released them and undid her shorts, pushing them and her panties down in one go, before stepping out of them. "There, now we're both naked and I can give you a proper hug." So saying she pulled Kathy in and squeezed her tight as their bodies melded together, breasts squashing against each other.

"What are we going to do? We can't stay up here, I've already had one ticking off from Mum for hiding away, and anyway lunch will soon be ready."

"No, I don't want to stay up here anyway, I want to see Tom's reaction when he sees me, he looks so hot your brother, and I want to see his cock when it's hard. Is it really big?"

Kathy thought back to her initial reaction when she first saw it, but since then she'd grown used to it a bit, and it didn't seem vastly different from her father's, "No, it's just normal," she stated as matter of factly as she could, wishing she had as much experience as her friend seemed to have.

They went downstairs into the kitchen where Kathy's mother was just putting the finishing touches to lunch, "There you are girls, can you call everyone in please?" They headed off to the lounge where Tom was still trying to solve the crossword.

He looked up as they entered and his jaw dropped as Sarah stood in front of him. She didn't have his sister's or mother's breasts, but her nipples seemed to stick out a good half inch. His eyes were on a level with her pussy and he could see her neat lips, just the hint of darker skin inside. "Your Mum says lunch is ready Tom." He could feel his cock reacting, the blood flowing in as it began to stiffen and he decided he'd wait a bit before getting up, no sense wagging an erect cock in her face. He watched as she sauntered out and into the dining room, repeating her announcement to his father.

Kathy had seen Tom's reaction and she'd seen his eyes following Sarah's neat bum out and she felt a sudden surge of jealousy run through her, it was totally illogical she knew, why shouldn't he react in that way, but still...

Once they'd gone Tom followed them through, his father he saw had a similar reaction to Tom's, his cock standing stiffly to attention. Their eyes met and his Dad shrugged as if to say, "What can I do?" His Mum was just sitting down and her eyes flashed to their cocks, for some reason she didn't look too pleased either, Tom was a little surprised, she'd taken in their previous erections without batting an eyelid, now things were a little different.

Nevertheless once their cocks were hidden under the table matters settled down and the chatter flowed round the table, talking about which universities they were hoping to go to and what holidays were being planned.

"Where did you go to nude beaches with your parents Sarah?" asked their mother, "I didn't think they were into that sort of thing."

"Oh France mostly," replied Sarah a little vaguely, "it was more Dad's thing than Mum's."

"I thought you went to Spain for your holidays?" commented Kathy.

"Yes, that as well."

Lunch over, Tom's Dad went back to work, his erection had mostly subsided, but Tom was still struggling a bit. "We'll clear up Mum," offered Kathy, "you prepared it all, so you go and have a sit down in the garden, you've been busy all morning."

"Thanks Kathy, that's sweet of you." She stood up then bent down to give her a kiss on the forehead and Tom got a ringside view of his mother's breasts dangling in front of his face which did nothing for his erection. To be honest, he wasn't looking forward to getting up, he had only just got used to the idea of his family seeing him with an erect cock, and now Sarah was in the mix as well. He couldn't very well refuse though, so he stood up and started to pick up the plates. Instantly Sarah's eyes flicked to his cock and he turned away quickly, but to his consternation the end brushed across Kathy's shoulder.

"Hey, be careful what you're doing with that thing," she shied away from him and he saw a smirk cross Sarah's face. There wasn't a lot of room with the three of them, and once or twice they bumped into each other, then Sarah's hand brushed across his cock, she apologised profusely, but to Tom it appeared deliberate. It was strange, two days earlier he would have delighted in the thought of his sister's best friend touching his cock, now it seemed embarrassing.

"You go and sit down Tom, you and that thing are just getting in the way, we'll finish up here," offered Kathy and Tom gratefully disappeared into the lounge once more to his crossword.

Finished, Kathy asked what Sarah wanted to do, suggesting they could go and sit with her mother outside, "No, let's go and sit with Tom, I haven't seen him for ages, and..." her words drifted away and Kathy wondered just what her friend was planning. The pair of them went into the lounge and Sarah immediately plonked herself down beside Tom, their bodies almost touching. Sarah recalled herself sitting just there not a few hours earlier and remembered the feel of Tom's hands on her and suddenly she wanted that again and sat herself down on his other side, determined that Sarah wasn't going to take him completely away from her.

"Can we help Tom?" asked Sarah coquettishly, her eyes dropping to his lap "With the crossword I mean." She reached a hand out and moved the screen slightly, her hand perilously close to his cock, "There, that's better now I can see it properly." Tom could feel one of her nipples grazing his arm, it was bullet hard and he shied away slightly, only for his other arm to collide with his sister's breast. Even she seemed to be pressing into him and he wondered how long he could keep his composure intact.

When Sarah rested her hand on his upper thigh he knew he had to get out of there, "Sorry girls, I think I'm going to give this a rest for a bit and perhaps have a snooze, I'll catch you later." He snapped the iPad shut and struggled to his feet, conscious his cock was now at their eye level and hurried out, heading straight for his bedroom where he shut the door and breathed a sigh of relief. His cock was positively aching and he began to stroke it, immediately feeling some relief, then he settled back on his bed and called up the search function on his stories website. 'Threesome + sister' returned hundreds of pages and he started to thumb through them as his hand settled into a comfortable beat, his mind picturing Sarah and Kathy in a tangle of limbs.

"That was a bit abrupt," commented Sarah.

"Well we were crowding him a bit, and he likes peace and quiet when he's doing his crosswords."

"Did you see how hard he was, I bet he's not doing his crossword now, I bet he's having a wank." If Kathy were honest with herself she would have thought that, but she felt compelled to defend her brother.

"I'm sure he's not."

"Bet you he is. Come on let's go and find out."

An image of Tom rubbing his cock sprang into her mind and suddenly it seemed to be a great idea. She stood up and pulled her friend up with her, then the pair of them climbed the stairs to the landing. Tom's door was shut and they crept up to it, both listening intently for any sounds. A floorboard creaked, "Shush," whispered Kathy sibilantly, pressing her ear to the door. Hearing nothing she stood back and rapped confidently on it.

"Hang on a minute," came a voice from within, but Sarah pushed past her, opened the door and went in. She could see Tom scrabbling to cover his cock with a pillow, but it was too late, it was blatantly obvious what he'd been doing, his iPad open beside him and his cock still clasped in his hand.

"Are you wanking?" asked Sarah bluntly. He could hardly deny it and he nodded, "Well we want to watch. We've never seen a man doing it before." Kathy looked at her, she certainly hadn't but she'd always been given the impression that Sarah was much more worldly-wise.

"What do I get in return?"

"We'll do it with you." Kathy looked at her in horror, there was no way she was going to do that, it was a private thing for her.

"It has to be both of you though." Sarah looked at Kathy who felt both pairs of eyes on her, she swallowed hard and nodded then followed her friend onto the bed, settling down on either side of Tom. Close up his cock looked big again, but she felt a little twinge run through her at the thought of what she was going to do. Sarah seemed more at ease, she lay back and parted her legs as her hand slipped between them and started to rub little circles round her pussy.

Tom was watching her, his hand stroking up and down his shaft, then he looked over at Kathy, the point clear. Timidly she pushed her hand down, her fingers encountering her folds and she slid a finger into her slit, she was surprised how wet she was, as her fingers slid easily up and down. Familiar feelings began to run through her and she allowed herself to relax, this could be fun after all she thought, as she toyed with her clit before pushing a finger delicately into her pussy. She couldn't help but let a little gasp escape from her mouth, both Tom and Sarah looked at her and she could see Tom's eyes widen as he realised what she was doing. Sarah was clearly not going to be outdone and pushed two fingers into her, pumping them forcefully in and out, her palm slapping noisily against her.

Tom couldn't really believe what was happening, he'd half expected something from Sarah, she'd been flirting with him after all, but to see his hitherto prudish sister masturbating openly beside him was a real treat, something he wasn't going to forget in a hurry. He could see her finger inside her, she was ramming it in and out as Sarah was and he wondered if she was still a virgin, either Sarah wasn't or she didn't care as her pussy was now making a decidedly squelching sound as she got wetter and wetter,

He saw she was tugging on her breasts, they weren't as nice as Kathy's, but there was something very enticing about her nipples. She met his eyes, "Can I?" she asked quietly. He wasn't sure what she was asking but he nodded, then got the shock of his life as she abandoned her pussy and made a grab for his cock, replacing his hand with hers. It took her a few goes to get a comfortable grip and establish a rhythm, but soon her hand was flying up and down, the wetness from her pussy juices making her hand slip easily across the skin.

It felt so much nicer than doing it himself and he recalled the way his father had reacted to his mother's handjob in the dining room. initially he just revelled in the sensation, but the lure of her nipples was calling him and he cupped a breast in his hand, fingers scissoring round the hard nipple. She gasped and pulled his hand against her, then eased it downwards, over her stomach and between her legs where she pushed it hard into her. He nearly came there and then, as his fingers made contact with her wet and soft folds, then he felt her guide him and one slipped inside her pussy.

He'd really only had his hand between a girl's legs a couple of times and only once had he felt a bare pussy, now he knew what all the fuss was about. He rolled over towards her and bent his head down, his lips made contact with her breast and he sucked a nipple into his mouth, nibbling the long hard bud with his lips and swirling his tongue round. He felt her tense, then relax and his hand was soaked in juices making her very slippery. He eased a second finger into her and pumped them in and out as he'd seen her do and he could feel her pushing up against him as the stroke on his cock started to become ragged.

Who instigated it he didn't know, but his body rolled further onto her and before he knew it he was on top, he felt the hold on his cock released, but his face was buried in her breasts, to be fair they had mostly disappeared, but her nipples still protruded upwards as his lips switched from one to the other. He knew from the stories he'd read what should happen next, but although the prospect of licking her pussy seemed immensely attractive, he hesitated, she seemed very wet and he couldn't help but wonder if it was pee, he didn't relish a mouthful of that, but it was clear what Sarah wanted him to do, her hips were pushing up against his abdomen and her hands were pushing him downwards.

He bowed to the inevitable and abandoned her nipples, sliding down the bed until his head was between her legs, He was scant inches away from her pussy, her labia were red and swollen and totally covered in a viscous fluid. Tentatively he pressed his lips to her, it left a sour taste on them, but it didn't smell like pee and with a little more confidence her pushed his tongue hard into her slit. Her reaction completely surprised him, she screamed loudly and her body went rigid, before she started to undulate her hips frantically, forcing his tongue up and down her increasingly wet slit. He chanced a look upwards, she had both her hand on her breasts, her fingers pinching her nipples hard, pulling them inches away from her body as her head lolled from side to side and her breath came in frantic gasps.

He flicked his eyes to the side, to his sister. Her eyes were locked on the pair of them, she was moulding a breast in one hand whilst the other worked busily between her legs, rubbing furiously up and down. He could see her folds parting, the pinkness apparent inside, then she too pushed two fingers into her opening.

Kathy couldn't believe what she was seeing, Sarah had made a grab for her brother's cock, then suddenly he was on top of her, sucking on her breasts, and then his mouth was on her pussy and she was screaming. Her first thought was how disgusting, then she began to feel a warm glow from her own pussy and she wondered what it felt like. All she wanted was to feel something inside her and she thrust two fingers in, she'd never dared do that before but they went in easily and it felt so good, her lips stretching open as never before, the juices coursing down inside her.

She heard rather than saw Sarah take two sharp breaths, then a third and a fourth and then her body started to shake and tremble and with a start she realised she was having an orgasm. Tom looked up in surprise, she could see he had two fingers stuffed inside Sarah's opening, but he'd clearly been taken unawares as well.

Slowly Sarah's body calmed, and Kathy could hear her murmuring, "Inside, I want you inside." Tom started to slide up her body, moving upwards until she could see his cock straining beneath him, then she saw as almost in slow motion it pressed against the folds of Sarah's pussy and then slowly disappeared inside her until their bodies were tightly locked together.

"Mmm, so good, now fuck me Tom." Her friend murmured as Tom's body began to undulate. Kathy's stomach lurched as she realised what she was witnessing, something told her she shouldn't be there, she should leave, but a more compelling force kept her in place, her eyes switching from Sarah's face to where their bodies were joined, where she could imagine her brother's prick opening up her friend's pussy and driving in, splitting her open, stretching her and forcing its way deep into her innermost core.

A surge of excitement went through her, automatically her fingers picked up the pace, thrusting rapidly in and out of her own pussy, her arousal beginning to build. She knew she could manage her orgasm, she'd done it many a time, allowing it to rise, then forcing it to abate, slowing herself down, only to let it rise again, each time a little higher until it was allowed to explode to overwhelm her senses in a maelstrom of sensations.

Both of them were making more noise now, each coming together of their bodies accompanied by small grunts of moans and sighs, how long would they last Kathy wondered, she wanted to time it right. It didn't seem as though it would be long, Tom's hips were thrusting almost violently into Sarah, she could see his body lifting away, could see his cock appearing, glistening from their combined juices, only to plunge back inside.

Their coupling became almost frantic, flesh slapping against flesh then she saw Tom lift himself up in straightened arms, a rictus of a grin on his face and then his body went totally rigid and she heard his breath rasping in and out of his nose. Sarah screamed once, "Yes!" and then she was trembling and shaking again, all co-ordination seemingly gone as her body went into spasms.

Kathy could feel her arousal surge, she caught it like a surfer catching a wave and rode it, allowing it to build and build as her fingers became a blur. She pinched her nipple hard, the pain adding to her excitement and then her body collapsed in on itself, waves rolling and crashing around her, barely conscious of her surroundings, until slowly the miasma cleared and she could see and think clearly.

Tom had collapsed on top of Sarah, both gasping for breath and as Kathy watched them he rolled away, his chest still heaving. She saw his cock slip from her pussy, already half its size as a dollop of white followed. He'd cum inside her, the thought barrelled through her brain, then she remembered Sarah telling her she'd gone on the pill and Kathy relaxed again.

Sarah's eyes opened, at first blinking as though she was having trouble recognising her surroundings, then she focussed on Kathy's face and smiled. "Wow, that was so much better than the first time. Did you cum as well?" Kathy nodded, then she realised what Sarah had said.

"What do you mean the first time? Have you only done it once before?" Sheepishly she nodded. "But you said you'd seen lots of cocks and c...."

"Well I might have been a little economical with the actualité."

"You mean you lied?" Another nod. "Who was your first then?"

"James."

"Your brother? Your brother took your virginity?"

"It's what all big brothers do isn't it? But he didn't cum inside me, we used a condom. It was so much nicer with Tom, but I didn't realise how messy it would get. I'm going to have to go home now, I can't go around with this dribbling out of me." She reached between her legs and dabbled her fingers in the white goo puddling between her legs.

"We ought to go anyway, someone will miss us and come looking," said Kathy, rolling off the bed. "Come on Romeo, up you get." Tom looked more as though he'd rather go to sleep but got up as well. He went into the bathroom and cleaned himself off, emerging just as Sarah was leaving, once more dressed in her shorts and tee shirt.

"That was great Tom, I look forward to doing it again, soon."

Kathy saw Sarah out then joined her brother as they went in search of their parents. Their father was still in the dining room working and they found their mother stretched out on a sun lounger in the garden. She stirred as they approached. "I must have dozed off for a bit. Where's Sarah?"

"Oh, she had to go Mum."

"Shame, I think she was starting to relax and enjoy herself."

"Yes I think you're right."

They spent the rest of the day lounging in the sun, eventually being joined by their father who seemed relieved that Sarah had in fact gone. Dinner was a relaxed affair and everyone seemed totally at ease in their skins.

It turned a bit chilly later, and rather than put clothes on while they watched TV, their mother fetched a couple of blankets and threw one at Tom and Kathy. "Here snuggle under this, your father and I will share the other one." Kathy took her mother at her word and snuggled into Tom's side as he spread the blanket round them. He was surprised that it felt natural, unlike when they'd been close while Tom was doing the crossword, he did get an erection to start with, but that soon went and even the presence of his sister's hand on his leg failed to stir him.

He could feel her breasts against his arm and he decided he preferred her much softer ones to Sarah's although there was still something special about those nipples, which thought did cause a momentary stirring. The film was entertaining, absorbing most of their attention, but in the light cast by the screen Tom could see his parents getting closer and closer, and he even caught them kissing at one point.

It ended and their parents got up, stretching, Tom could see his father had an erection and he wondered what his mother had been doing to cause that. "We've got work tomorrow so we're going to call it a day, don't stay up too late will you." They hugged and kissed each other goodnight and Tom and Kathy settled back down once more. Tom found he didn't really want to move, but there was nothing on, and reluctantly they accepted that the day was over.

At the top of the stairs they stood facing each other, it had been a strangely intimate day, Kathy and her brother had barely touched each other, well not until they had cuddled together under the blanket and somewhere deep down inside her something was telling her that there was more to be had. She wondered if they could get into bed together, but that would send the wrong signals, she wasn't sure she was totally ready for that, and anyway her parents would go spare if they found them like that.

She settled for pulling Tom in for a hug, their bodies pressing together. His cock wasn't hard but it wasn't soft either and she could feel it against her lower body, for once it was a comforting feeling and for a brief moment she pictured it inside her, but rapidly thrust those thoughts away. Their lips met in a kiss, a tender kiss but not as lovers and Tom's hand brushed across her breast, then he was gone, his door closing behind him.

A little sadly Kathy went into her room and closed the door, then pulling on a pair of panties slipped into bed. As she settled and the room became quiet she could hear it, the unmistakeable sounds of her parents making love, there were no loud screams, no exhortations to "Fuck me harder", just the soft moans and grunts of two people immersed in their love. She thought back to watching Tom and Sarah have sex, that hadn't been making love, just sex and a little twinge went through her pussy followed by a trickle of juice.

The orgasm she'd had whilst watching them had been the best of her life, she tried to imagine herself in Sarah's place, Tom's cock thrusting into her pussy and unbidden her hands slipped between her legs. No, she told herself she wasn't going to masturbate, but her hands were pressing against her pussy and gradually they began to move, pushing through the soft material into her slit. One hand found her clit, her fingers played with it sending little jolts through her, even reaching up to her nipples to make then tingle. She thought back to Sarah's nipples, Tom had seemed fascinated by them, hers seemed boring in comparison and she'd never cum from just playing with them. Perhaps it would be different if someone else played with them, she recalled the feeling of being nestled close to her brother, then his hands had been on them, only for a fleeting second but it had felt so good.

A surge of juice went down her tunnel, good job she'd put her panties on she thought, wet patches and stains on the sheet were so embarrassing. What was Tom's bed like she wondered? Sarah had leaked profusely all over it and then cum had leaked out of her pussy, mind you if Tom masturbated as much as she thought he did then it was probably covered in stains. He didn't seem at all embarrassed when his mother changed the beds which she did frequently.

Another rush of juice and she slipped her hands down the front of her knickers, her fingers brushing over the soft folds of her pussy, they were damp and slippery and she eased her fingers along her slit, sliding from clit to pussy. A virgin pussy still, although she'd now had two fingers inside her, that had felt much better than one, but still nowhere near as big as a real cock.

A shiver went through her at the thought of something that big inside her, she'd been amazed how easily Tom's cock had slid inside Sarah's pussy, one minute it was there, the next it was buried deep in her and she hadn't seemed to have experienced any pain at all, in fact she'd revelled in it.

Her Dad's cock was pretty big as well and from the noises still coming through the wall her mother was enjoying every minute of it. She pictured them together and a flood of pussy juice covered her fingers, she pushed two against her then resolutely inside and immediately a surge of arousal went through her and she began to plunge them in and out, her palm pressing on her clit.

Faster and faster she thrust, she could feel her orgasm starting, a tiny seed inside her, growing, expanding, the warm feeling became a fire and then she exploded, writhing and shuddering in her bed, then all was still apart from the thudding of her heart. The sounds from next door had stopped as well, had they finished or embarrassment of embarrassments, had they heard her?

Gradually she relaxed and sleep overtook her, the night full of dreams, everyone naked and writhing together in one enormous bed, cocks in pussies, mouths on pussies and hands and fingers everywhere.

Tom had no difficulty in going to sleep, he couldn't hear his parents and although he'd briefly toyed with his semi-erect cock it wasn't a serious attempt at masturbation, just the comforting of an old friend. It had been a fabulous day, one to remember, his mother and sister naked, and then fucking Sarah, his sister's best friend, whom he'd lusted after since he first discovered the wonders of the fairer sex. Not only that but Kathy had got herself off beside them, he still had difficulty in believing his sister could be like that, but then in the evening she'd snuggled up to him and he'd felt closer to her than ever before.

He woke to the sound of showers and the rattle of dishes in the kitchen and then he remembered both his parents had said they were at work. That meant he and his sister would be home alone all day and he wondered how they'd react to each other after the events of the previous day. He rolled over onto his back, still half asleep and his hand found his erect cock, that was no surprise, he woke every day to a hard-on and usually had a wank unless he was late. Today there was no rush and he lay there, his hand steadily running up and down his shaft as familiar feelings began to course through him. He checked there was a supply of tissues readily to hand, his mother kept the box topped up, she must have thought he had a permanently runny nose to do that.

There was a knock on the door and it opened and semi-annoyed at the interruption he stopped masturbating. It was his mother dressed in trousers and a blouse. His mind flashed back to the day before and he wondered if it had all been a dream. It couldn't have been, the memories were too clear and fresh to be anything but real. "I'm just off to work now Tom, there's some leftovers for lunch and I'll be home about five. Have a good day and don't annoy your sister too much." She leaned over to kiss him lightly on the forehead and automatically his eyes dropped to peer down her gaping blouse, but she'd put her hand to her chest and held it close to her preventing him from seeing anything of interest.

He thought that strange, yesterday she'd spent the entire day fully naked with him, and now she seemed worried about him seeing her bra enclosed breasts. Oh well, that was life and he'd better get used to normality again.

"Bye Mum, have a good day," he called to her retreating back as she shut the door again and he resumed stroking his cock. He heard the front door close and the sound of her car starting and was just about to throw the covers back to facilitate his session when there was another knock on the door. He hadn't heard her come back, which meant that it must be Kathy.

"Come in Sis," he called out, stopping again although he kept hold of his cock and retained his interest by squeezing it, just as he imagined a milkmaid would the teats of a cow. The door opened and she stepped in, she was wearing just a pair of panties although she had one arm crossed over her breasts preventing him from seeing anything bar some under-boob, "What's up Kathy?"

"I really enjoyed Nude Day yesterday, I didn't think I would but I did, and I just wondered what we were going to do today, whether you had anything planned?"

"Not really, why?"

Tom watched as she let her arm fall and sat down on the edge of the bed, there were her breasts again, just as he remembered them only better. Without thinking his hand resumed stroking his cock, the movement making the covers bulge regularly. Kathy's eyes went to it, "Are you....?" He nodded.

Her eyes returned to his and she looked as though she was trying to make up her mind about something, then abruptly she stood and pushed her panties down round her ankles and stepped out of them.

Kathy's Mum had come into her room to say goodbye and she listened for her to leave the house. Once the sound of the car had faded she rolled out of bed and with her arm firmly crossed over her breasts made her way to her brother's room. She didn't really have a plan of what she was going to say, she just felt she wanted to be close to him, and spend some time together during the day. He was lying in bed, she could see his bare shoulders and she wondered just what else he was wearing.

The comment about National Nude Day just slipped from her mouth and then it seemed silly after yesterday to cover her breasts up and she dropped her arm. Her eye caught movement in the covers and suddenly she knew what he was doing and she felt wetness between her legs thinking of his erect cock just separated from her by a few layers of material. Up she stood and slipped her panties down, stepping out of them, then with barely a pause she pulled back the covers of his bed and slipped under the duvet. It was lovely and warm and smelled vaguely of sex, she turned to him and reached downwards to his waist, finding his arm and following that until she came to his hand clasped round what seemed to be an enormous iron bar. Her hand wrapped round the part not covered by his hand and Kathy realised she was holding her first cock.

She felt Tom release his grip and she slipped her hand lower, she was barely able to get her hand round it and she was surprised how... alive it felt. Sure it was rock hard but covered in a very warm, soft skin that seemed to slip easily up and down the hard interior. Her mind flashed back to watching Sarah slide the skin along the hard shaft and she mimicked her action, she could feel ridges and what felt like veins, and the top was a completely different texture.

It was no good just feeling it and she peeled back the covers to get a better look. Of course she'd seen it the day before, but this was right up close to her face, and she could make out every detail, the bulbous end with a strange ridge round the top, a small slit in the end that she assumed was for pee and semen. All in all it was pretty big and fat and she still wondered how it would ever fit inside her. Inside her? Where had that thought come from? To be honest she didn't really know what she was doing in Tom's bed in the first place, she'd just felt a compulsion to be close to him again and now she was effectively masturbating him.

A groan escaped his mouth, "Am I doing it wrong?" she asked, concerned that her very first handjob was doomed to failure.

"No, not at all in fact it's perfect, just keep doing that." 'That' in fact was a bit tiring and Kathy slowed down a little and shifted position, inadvertently running her hand over the end causing Tom to gasp. Impishly she did it again, this time she could feel something wet lubricating her head which made it run a bit more easily. Must be the same as when her pussy gets wet she thought.

She felt Tom's hand rest on her hip, it felt intimate and she had a sudden desire for him to touch her breasts again, "It's all right Tom, you can touch me," she offered, expecting to feel his hand slide up her body to her chest. Instead it made a dive between her legs and before she knew what was happening he had cupped her pussy in his hand and was pushing a finger into her slit. Instantly her body tensed and she stopped stroking him.

"Sorry," he apologised, "only you said it was OK." It seemed churlish to nitpick what she'd meant when she was holding his cock and she allowed her body to relax and mould against him.

"It is, I was just a bit surprised, that's all."

"I can stop if you want."

Kathy realised that was actually the last thing she wanted him to do and she shook her head, "No, it's fine, I like you touching me there," She did, she really did she discovered, it was sending little tingles through her pussy and she could feel the trickles start in her tunnel, and her nipples were positively glowing. "Tom, will you kiss my breasts?" The words were out before she could stop them and obediently Tom lowered his head to her breast, just above the nipple. It felt so sensitive she could feel his breath on it and then his mouth closed round it and she felt a lurch in her stomach, surely she wasn't going to cum just from one kiss, she didn't but the warmth from her nipple started to spread across her chest and when he switched to the other side it was as though two fires had been lit.

Her juices were surging down her now, she could feel the slickness against Tom's hand and then his finger eased back into her pussy. Her own had been inside her countless times, but this felt so different, so much better, then when a second joined it she thought she was going to pass out. All she wanted to do was to buck her body against him, to force his fingers deep into her cunt. The word had sprung into her mind, somehow it seemed so right at that moment.

"Tom, will you kiss my cunt like you did Sarah's." Ever since she'd seen Tom do that it had seemed like the most erotic thing that could happen to anyone and she'd seen Sarah's reaction, her body bucking and writhing as her orgasm had hit her and she wanted to feel the same, to feel her brother's mouth and tongue on her most intimate place.

Tom looked up at her, a question in his eyes and she nodded, then she felt him start to slide down her body and the anticipation flooded through her, he took his time, kissing down over her stomach and then over her mons, kissing all round her vulva but never actually touching it. "Tom," she pleaded, wanting nothing more than his mouth on her.

Then his lips touched hers and it was like a electro-static shock, she tingled all over and then when his mouth closed on her and his tongue pushed into her slit a firework display erupted in her senses, and her body shook as she was swamped with waves of pure pleasure coursing through her entire being. She screamed, she knew she did and she felt Tom's head lift away and there was just an empty feeling.

Her hands dropped to his head and seized it, thrusting his face down against her again, her hips bucking, pushing him into her. She felt his tongue again, sliding up and down her slit, one minute flicking at her clit, the next delving into her pussy itself. She rode the rollercoaster of pleasure, everything rising and falling at an incredible pace and then it hit her and she was cumming, indescribable sensations roaring through her, emanating deep in her pussy, expanding outwards and then unbelievably, starting again. It seemed to go on forever, but then she felt her body start to relax, little aftershocks still rippling through her, but then a calmness came over her and she lay back.

Tom couldn't believe how his sister had reacted, she had been like a woman possessed, her body shuddering and trembling and the scream she had loosed, well it was a good job the house was empty or they would have had parents demanding to know what the matter was. He looked up from between her legs, Kathy was lying back on the pillow, her eyes shut with a look of peacefulness on her face, so different from just a few moments earlier. He didn't really know what to do, his cock was demanding attention and it wasn't going to get any in that position so he slid back up her body, still between her legs until their heads were level once more. He could feel his cock nudging at the junction of her legs, all it would take was one push and he'd be inside her. But no, his brain told him, this was his sister and he strongly suspected she was still a virgin. But still he was tempted, Sarah had been tight but the feeling when he entered her had been heavenly and he so much wanted to repeat that.

Kathy opened her eyes, "Tom, what did you do to me? That was the most fabulous thing I've ever felt and I can't wait for you to do it again. But now I want you to make love to me. Properly."

"But aren't you a virgin?" he stuttered.

"Yes but I want you to be my first, apparently it's traditional, and you are older than me."

"Only by 20 minutes, or so Mum says."

"I don't care, just make love to me."

Kathy could feel Tom's hard cock pushing against her, between her legs, seeking her opening but either he couldn't find it or his cock was just too big because all it was doing was slipping and sliding about. "Here, let me help you," she offered and reached down between them to grasp his shaft. It seemed bigger than ever and as she held it in her hand she had doubts that it would ever fit.

She felt the tip engage in the opening of her pussy and her body automatically tensed, then she heard her brother say, "Relax Kathy, it'll be all right, I'll be as gentle as I can." She forced her body to relax, but mentally prepared herself for the excruciating pain she had been told would follow.

Instead all she felt was a steady pushing against her entrance then a feeling of opening up, her lips stretching to accommodate the invasion of her body. To her surprise there was no pain whatsoever, just a gradual feeling of being filled up, accompanied by the most warm, replete sensation as his cock pushed deeper inside her. It seemed to keep on going in then he came to rest and already she could feel herself tightly enveloping him.

"Is that OK Kathy?" Tom asked tenderly, "I haven't hurt you have I?"

"No Tom, it's even better that I dreamed it would be, and don't worry, I'm on the pill." She felt Tom start to pull his cock out of her, could feel herself closing up behind him, then just when she thought he'd pull right out he pushed firmly back inside. The sensation that rushed through her was pure heaven, of excitement, euphoric and then he did it again and she felt it once more, the hard rod that was his cock stretching her open, every nerve ending tingling. And then she could feel him pumping into her, establishing a steady tempo and she was almost swamped by the sensations relentlessly running through her.

A warm glow started deep inside, she recognised it, another orgasm was brewing, this time it grew rapidly and burst through her leaving her head swimming as the blood rushed in her ears. She could feel her pussy pulsing, clamping round Tom's cock and at the back of her mind she wondered if he was cumming, but there was no sensation of anything squirting into her pussy and she felt him stop and slowly her headiness abated and the world returned to normal.

The normal that was the seemingly relentless thrusting of Tom inside her, this time it seemed as though he was pushing deeper and faster into her, his hips slamming against hers and she could tell he was getting close, his breathing was getting ragged and his movements less co-ordinated. She squeezed with her pussy and it felt tighter, the nerve endings more stimulated and she heard him gasp then suddenly his body went as rigid as a board and then she felt it, an explosion of warmth inside her, a feeling of complete fullness and she knew his cock was erupting into her, filling her with spurt after spurt of hot thick cum.

Then she too was skyrocketing again, exulting in the feeling inside her, her mind soaring as wave after wave pulsed through her and then it was gone and she felt Tom collapse on top of her. She could feel his cock still inside her, still hard and for a minute she wandered whether it would ever go down, but then something moved and she could feel it shrinking until it slipped from her pussy. A feeling of emptiness came over her, even more so when with a groan Tom rolled off her and lay panting beside her. She could feel his cum slowly leaking from her lips, strangely it felt quite pleasant, still warm and gooey, even when it trickled over her bum.

She reached down and ran her fingers over her pussy, it still felt exactly the same, she hadn't really known what to expect and she grinned at the thought of finding it massively enlarged, now that wouldn't do for when she and Tom made love again. Had she really thought that, that they would do it again, suppose he was feeling guilty for what they'd done, suppose he didn't want to do it again?

As if he'd felt the thought he opened his eyes and turned to her then reached out a hand and gently cupped her breast, his fingers brushing over her nipple which felt really sensitive. "That was wonderful Kathy, I hope it didn't hurt too much. It won't be as bad next time." A thrill ran through her at the words 'next time'. She couldn't wait and somewhat uncertainly reached down to caress his soft prick.

"Tom?" she ventured tentatively, "How about we don't put any clothes on again today, we can have our own Nude Day, as long as we're dressed by the time Mum and Dad come home they'll never know, and then we can make love whenever we want." She felt his cock twitch and then incredibly start to swell and she knew that she didn't have long to wait.
