Day 1 -- Saturday

I wasn't too keen when my parents announced that her parents would be staying with us for 3 weeks. I had hardly ever seen them because they are constantly on the move, traveling around the world after their early retirement. The last time any one of us saw them in person must have been when I was around 12. I'm 18 now.

"Don't look so glum," my mother had said. "They'll only be here a few weeks and then they'll be back on their way. Besides, they want to see you, now that you're 18; AND your sister, to see how you two have turned out."

My sister had shrugged; in fact, she was looking forward to seeing them. Me, huh, I was told I'd have to give up my room for 3 weeks or so, because my room was bigger and had a bigger bed. I was to sleep on the settee in the lounge because we only had a three-bedroom house. That was the other reason I wasn't keen on their arrival.

**

"Well, hello there young man," said the old man as he walked in the front door and shook my hand, "You must be Rick."

"Yes, hello Grandpa Pedro," I said as cheerfully as I could muster to comply with my mother's wishes. He then greeted my sister Bella, which raised my eyebrows. He hugged her; but wasn't that unnecessarily too tightly? I thought. He basically squashed my sister to his body. Bella's 21, much wiser to the world than me, but I saw the surprised look even on her face.

After greeting my parents, Grandma Irene turned to me.

"Why, hello handsome. You look dashing!" she said, and she plastered her body to mine, getting the same treatment Grandpa Pedro gave my sister. I tell you what, that hug was tight. I could feel her big ample breasts squashed against my chest! She's a big woman - as in chubby - so there was a LOT of her I had to get my arms around.

She held the hug a tad longer than I thought was necessary, but that meant I got a good feel of her body; her chubbiness giving her a nice, all-round softness -- surprisingly quite pleasing, I thought. Also, I couldn't help my fingers feeling her bra straps on her back, which made me feel a bit more awkward.

And to complete the awkwardness, as she disengaged from the hug, she gave me a quick peck... on the lips! And a pat on my bottom!

As I tried to come to terms with the new arrivals, I was surprised, as well as Bella, to see Grandma Irene give the same greeting to my sister! I could clearly see their breasts squash against each other's!

I shook my head to clear it, thinking these two were strange characters; probably something to do with their old age that they're so touchy-feely. I had been told Grandpa Pedro was 67 and Grandma Irene 65.

**

After they had been shown to their (my!) room, my father and I were sitting in the front room with my grandparents, listening to their adventures, whilst my mother and sister prepared some refreshments.

"Oh, Rick, you've no idea what the world has to offer. You've never been abroad, have you?" Grandma asked.

"No," I replied. I don't know how she knew... wait, mum must have obviously been in touch with them occasionally and told them. Yeah, we only holidayed within the country, couldn't afford foreign travel.

"But all that walking, it does take a toll on one's feet." To highlight her point, she raised her leg and, placing her foot on the couch, proceeded to massage the foot in sympathy.

All our eyes naturally focused on the foot in question. But I nearly choked on my spit as my eyes were instantly attracted to the bright red contrasting against her pale thighs. For a second I blinked to clear my eyes to clarify what I was seeing. I looked up, but Grandma was oblivious and continued her monologue and tending to her foot; and dad and grandpa couldn't see from their angles. But I could see right up Grandma Irene's dress; she was wearing red panties! The triangle of red contrasted brightly against her pale, meaty thighs.

My eyes quickly and nervously darted around the room again to see if anyone noticed me looking up my grandmother's dress. No one. So, I absorbed the vision into my soul as deeply as I could for later processing.

Oh, yes, upskirt has been one of my favorite porn genres and real-life school pursuit. But getting an upskirt of a woman in her 60s was a first!

Then the foot was down as my mother and sister brought the refreshments.

But now I got more titillation as Grandma Irene bent forward to pick up her drink and nibbles. Those ample breasts of hers almost spilled out of the top of her dress, exposing great expanse of her cleavage and flashes of her red bra. For some reason I found it surprising that a lady of these advanced years would wear matching underwear -- her bra and panties were of the same shade of red! My mother and sister didn't usually go around wearing matching bras and panties. I know, OK? If you live with people, you get to know a few personal things about them. Besides, red seemed a bit racy for everyday wear.

With a start, I came back to reality. I couldn't believe I was so deep into analysis of female underwear, in particular my grandmother's!

The rest of the evening went by uneventfully, with further amazing stories from my globetrotting grandparents.

------

Day 2 -- Sunday

Damn, that was an uncomfortable night. I woke up the next morning with stiff shoulders and neck and legs, finding the settee too uncomfortable and too short for my 6 feet length/height -- I couldn't stretch out fully like on my bed. And to top it off, it was freezing in the open-plan downstairs with tiled floors. It hasn't yet snowed, but the winter season does make the tiles cold. Upstairs, it's all carpeted.

"How was it?" mum asked the first thing when she came downstairs to prepare breakfast.

"Not good. I'm stiff all over and the settee is not long enough."

"You'll get used to it," my dad chipped in, being stoic as ever.

Alright for HIM, he's still got his warm bed... and mum... to keep him company and warm.

"But it's also so cold, mum," I pleaded.

"We'll get you another blanket," mother said, trying to be helpful but I wasn't sure that would solve my problems.

To drain my energy thus induce sleep, I did let one out during last night, and had caught the ejaculate in some tissues, whilst thinking about Grandma Irene's bra and panties. It was a strange session; I don't normally masturbate to images of women in their 60s, but this was a ready-made upskirt, right in our home! And the feel of her large soft body and her tits on my chest, plus her kiss on my lips, it all added up to a very different and interesting half hour of jerking off.

Yeah, that was about the ONLY good thing about my night.

"Good morning!" a cheerful voice sang.

I looked around and my jaw dropped. It was grandma. She was still in her night wear -- a thigh-length figure hugging number with spaghetti straps. Each step she took made her braless breasts swing ever so noticeably and exposed more of her smooth chubby white thighs. Right there I was converted. Until now my sexual fantasies consisted of girls from my school and the sexy young teachers. But right there I was converted to include mature chubby women as well. Her ample curves were spellbinding.

With her long flowing black hair (must be dyed), her 5'4" scantily clad figure moved gracefully across the floor, accompanied by her balding slim husband, who was about 5'6", wrapped in a robe.

By the time they reached us, it was difficult to ignore two other guests waking up to greet us. The constant rubbing against her nightie and the cool room, excited grandma's nipples, encouraging them to make an appearance; to poke out and make obvious peaks on her chest. Mum gave her mother a funny look but said nothing. I saw dad also notice. My sister wasn't up yet; it was Sunday morning after all.

Nothing much happened during the day, except my grandparents got settled in and told us more about their travels... and I got another, albeit brief, upskirt views when Grandma Irene accidentally flashed me her light blue panties a couple of times during the day. And through peeks down her top, I noted she was wearing a matching bra.

Did grandma always wear matching bra and panties set?

------

Day 3 -- Monday

Next day I went off to school and my sister to university - lucky for her, it was within commuting distance from home. My dad went to work, but mum only worked part time so, she was able to spend more time with her parents.

"How was school?" Grandma Irene asked cheerfully when I returned home.

"Lousy," I responded.

"Really? Why? You got bullied?"

"No!" I shot back in surprise. I'm 6 feet tall and of average build, not some weakling. "I kept falling asleep in class. I got told off."

"Oh, dear. Why?" mum asked, showing sincere concern.

"Coz I can't sleep at night," I moaned.

"It's because of us, isn't it, taking your room? Maybe we should sleep downstairs," Grandpa Pedro offered. He's not a man of many words, but he did offer now.

"No, dad. You can't, you need your bed," mother objected. "We'll just take the spare mattress off your bed and put it on the floor. Rick can sleep on that. That way he'll be back in his room, but you'll still be on a bed."

"You mean share my room? Sleep with-?"

"Yes. This way everyone's happy," mother interrupted.

"But...' I said.

"But..." Grandma Irene said.

"No buts. It's settled." Mum can be so domineering sometimes. I wasn't sure if this was really a good idea.

**

Now, I may be sleeping on the settee in the lounge, but my bedroom was still my room with my clothes and things. It was while I was doing my homework at my desk in my bedroom that Grandma Irene decided to cut her toenails sitting on the bed.

I didn't think much of it at first.

"Don't mind me," she said, "I'll be real quick."

And as she cut her nails, she eagerly recited a few more snippets of stories from around the world. I only half listened whilst doing my homework; I guess she was somewhat distracting, but I didn't have the guts to tell her.

But that was nothing compared to the distraction that caught my eyes. For, when I looked towards her, I froze and stared wide-eyed, totally unbelieving the sight before me. Grandma was merrily talking and cutting her nails, keeping her head down, but to cut her toenails she had to sit with one leg on the bed, the other bent up. With her skirt being tight, it stretched across her lap, exposing everything under her skirt. I fucking had a clear view right up her skirt!

Grandma Irene maybe in her 60s and chubby with a nice round face and a few unavoidable wrinkles, but she wasn't fat, nor flabby, giving her thighs a very nice enticing firm, smooth look, right up to... the very top. Grandma Irene today was wearing pink panties -- a pink bra and panties set -- that was tightly snuggly covering her pussy. And I tell you, with the light from the window providing illumination, I'm SURE I could see strands of her pubic hair! What's more, she was oblivious of her exposure.

My cock stirred and rose, tenting my pants, as if it sensed a sight worth seeing and wanting a look itself.

Every now and then she did look up, but I quickly looked away, back into my books... but of course my gaze was lecherously drawn back to her panties. An upskirt, right here in my very own fucking bedroom! FUCK! I was shaking and hyperventilating... sort of.

When she left, I sat there for some time replaying the vision, as if the image of my grandmother's pussy was etched in my brain. I couldn't believe it, for 18 years nothing from my mother or sister, but 3 days my grandmother was here and each day I got to see up her dress or skirt... and plenty down her tops! It was screwing up my head.

Red, light blue, pink. Each day a different underwear set. How many sets of matching underwear did she have? Was ALL her underwear matching sets?

Then a thought struck me. Why not? I thought. I made sure the bedroom door was closed before approaching my grandmother's suitcases. They were only gonna be here for three weeks, so they didn't unpack, other than a few items to hang up.

Knowing I was doing something wrong -- breaking trust and invading privacy - with shaking hands and regular look at the bedroom door, I opened grandma's suitcase. I didn't need to rummage around, all her underwear were there, neatly folded... in matching bra and panties pairs: black, white, yellow, navy blue, etc. And there were some non-matching items as well after all.

Instinctively, I took out and unfolded a white bra, a lovely, lacy number. Examining the label, it gave the size 38D. Big! Holding up the matching cotton panties in my hands, they also looked big. I noted the lacy trim around the edges and the lace panel at the front, through which her pussy hair would be visible; and I couldn't help fingering the cotton gusset where her pussy would be.

Hearing footsteps on the stairs, I quickly returned the intimate items and closed the suitcase and got back to my desk. I was breathing hard, not believing what I had just done. I really needed to jerk off.

**

That night, it was a bit awkward trying to get into the rhythm of the new sleeping arrangement. First, I changed into my pyjamas whilst my grandparents went to the bathroom, then vice versa.

Getting into bed -- me on the thin spare mattress on the carpeted floor and my grandparents on my bed -- we exchanged some pleasantries before saying our good nights, me acutely aware of the big pink bra draped over my chair; grandma hadn't even covered it with the other clothes she'd taken off. In the relative darkness, the pink seemed to glow, drawing my attention.

In the quiet stillness of the night, the major drawback dawned on me: how was I going to get my jollies? I was too aware of my grandparents' presence; I didn't even touch myself, afraid they'd see me, even though I was under a thick duvet. At least downstairs I was able to freely pump away.

It didn't matter, though, I was too tired from lack of sleep from the past two nights, and I was out like a light before I knew it.

------

Day 4 -- Tuesday

In the morning, it was a different matter; I woke up with my usual morning wood. Damn, I was dead keen to tend to my neglected friend, but I was too scared, all too aware of my grandparents and the additional morning light illuminating the room.

But luck would have it, my grandparents got up, and both went to the bathroom together! Quickly I grabbed my stiff straining pole and rapidly stroked myself staring at Grandma Irene's big pink bra, enjoying the direct stimulation and the feel of my own hard cock.

I didn't know how long I had before they'd return, so I didn't dally around and just let myself go with deep satisfying grunt at the first tingling feeling, catching my discharge in the tissues I keep in my pyjama pocket.

As soon as my grandparents returned, I dashed out and chucked the soiled tissues in the loo and did my morning things. With only one bathroom (with a combined loo and shower) in the house we know not to hang around too long in there; so, wanking whilst taking a shower is a no-no, it would be selfish hogging of a much used room.

At breakfast, with me dressed, ready for school my grandparents joined us and I still couldn't keep my eyes away from those free-swinging pendulous breasts. My mother and sister also didn't wear bras in bed; but if they came down in their nightwear, they always wore a gown to cover themselves. But Grandma Irene seemed nonchalant about walking around in her skimpy short nightie.

I wasn't complaining. More than once I got a good clean view down her front when she bent to reach for something on the dining table, her heavy breasts forcing the nightie down, exposing a large expanse of her cleavage.

What's more, it gave me great satisfaction that I knew she was wearing pink panties under that nightie.

**

I said it before, but in all these years living with my mother and sister I barely got a glimpse of anything titillating, but with Grandma Irene being only here a few days I already got three days of upskirts and plenty of partial peeks of her breasts!

I mean today, after school, she hugged me tightly, welcoming me back from school, pressing me against her soft body, and I felt her breasts oh, so noticeably. And when she bent down to pick up something I almost saw her arse as her skirt rode up. Then, when she sat down on the settee, I could see up her skirt... all the way to her yellow panties! Especially when she crossed and uncrossed her legs.

It was all so confusing and messing with my mind. What's more, I didn't have my own room anymore to have a nice long pumping session or two.

Incredible as it may seem, it seemed like my grandmother could read my mind. That night as I got into my 'bed', she switched off the light and kneeled next to me.

"Rick, dear," she whispered in my ear, "We know you're young and have your needs. We don't mind if you want to take care of yourself. OK? And sorry for taking your room and privacy."

"Huh?" I was stumped. I wasn't sure what she was talking about. More so, I wasn't really paying attention to what she was saying, because my eyes were looking down the top of her nightie that had helpfully opened up as she knelt so close to me. She knew I was looking there but did nothing to cover up.

"This," she said, patting my penis," You can do your thing. It's OK if you want to masturbate." That was clear enough! Saying that, she quickly kissed me on my lips and got up. As she walked to her bed I followed her in shock. As she climbed onto the bed, with her legs separating, I got a very clear view up her short nightie from my vantage on the floor. I saw almost all of her arse and her yellow panties tightly covering her pussy. My eyes then settled on her bra, once again openly draped over my chair; the yellow almost glowing in the dim light of the bedroom.

I was rock hard. But how could I touch myself? No way, not with them knowing AND looking! I suffered through the night, unsure that my grandmother really did touch my cock.

------

Day 5 -- Wednesday

It was morning when I was again able to quickly wank and let one out whilst my grandparents went to the bathroom together.... again!? They do their morning business in front of each other?!

When it was my turn to use the bathroom, I couldn't help noticing the used pink panties from the previous day in the laundry basket. The draw to them was magnetic, for I was now taking a keen interest in my grandmother's underwear!

It felt odd and like invading privacy; and I felt like a pervert as I held up the pink panties. I don't know why, I had never before done such a thing, but I sniffed them -- yes, sniffed my grandmother's used panties. Amazed that I was, in effect, smelling my grandmother's pussy. It made my head spin. Rummaging around a bit more, I found the light blue and the red panties. Again, I looked inside and smelled them. The bras didn't have any distinct smell, I noted.

Even though the bathroom door was locked I felt nervous, as if someone will see me, catch me. My heart thumped with anxiety. Carefully I returned the items in order, putting the older items lower down in the laundry basket.

**

Getting ready, I hurried to breakfast, where each morning it seems we are treated with my grandmother's distracting bouncy tits. And when I returned home from school, I got the same VERY personal hug. But I noticed my sister also getting the same hugging treatment when she returned from university, including from my grandfather... too tightly, I would say.

I spoke my sister Bella about that. She put it down to their age, saying most old people are too touchy-feely.

"Yeah, it's embarrassing how they squeeze me, both of them," she said, making a funny face. "But don't worry, they won't be here for long. And anyway, you should be happy, grandma is about the only girl that you get to touch."

I shook my head. She just couldn't resist a dig.

I was going to ask her about how it felt having grandma's big tits pressing against her own decent sized tits -- C cup, just like mum's -- but I didn't have the guts. You see, we don't really get along too well; we've never clicked; to our parents' dismay, we have too many arguments. So, mostly we stay apart and do our own things. She's pretty, long black hair, decent body and tits -- as I've already said -- but that's about it.

**

"Rick, sorry to trouble you whilst doing your homework, but can I ask you to zip me up?" Grandma Irene asked. "My zipper seems to be stuck."

Yeah, I was doing my after-school homework in my room, so she'd gone to the bathroom to get changed - mum was taking grandma somewhere. Presenting her back to me she stood expectantly in her open black dress.

But I froze. Fucking hell, her WHOLE back was exposed! My eyes traveled from the top, where I saw her red bra band, to the bottom. Fuck, I could see the tops of her red panties! The whole picture was just so fucking sexy and erotic. I don't think she actually realized what she was revealing to me... and what it was doing to me just looking.

"Please. I can't move the zipper, it seems to be stuck somehow. Can you free it?" she asked again after no movement from me.

"Su... sure. I'll take a look," I said. But I was doing more than looking... I was ogling, lustfully ogling the big expanse of her naked back, her exposed bra and... and her panties.

With shaking hands, I grabbed her open dress and tugged. Her panties pulled at the same time.

"I think it's stuck with your... um... your panties," I said nervously.

"Can you free it?" No hint of embarrassment on her part, not even a thought of this possibly being inappropriate to ask a horny boy.

"I'll try." With one hand I held the zipper, with the other shaking hand... I held the top of her panties. FUCK! I was holding and pulling my grandmother's panties, panties she was wearing! These were the high-waisted red ones that she was wearing on the first day. Mum must have done the laundry today because I knew from perving in her suitcase, grandma had only one set of red bra and panties set.

Eventually, I freed the zipper and zipped up the dress.

"How do I look?" she asked, turning around and presenting her front.

"You look great, grandma!" I said. Inside AND out I thought, since I knew what underwear she was wearing. I knew EXACTLY what her underwear looked like.

After grandma left the room, I found it hard to concentrate on my homework; my mind kept wondering off to what I'd seen and touched. I wanted to get my pulsating cock out and give it a good shake, but I daren't coz my grandfather was still home, along with my dad and sister.

**

OK, so I'm lying in bed at night, thinking about what my grandma told me, about it being OK to jerk off with them in the room. I desperately wanted to do it, especially after the past few days of peeks of her naughty bits. Cautiously I ventured my hand down south and found my cock half ready. Turning onto my side, facing away from my real bed, I started slowly, all too aware of the awkward presence in the room.

It felt good to touch myself, to feel the hardening length as my cock continued to grow. It wasn't the images of the girls at school, nor the teachers that came to my mind, but, surprisingly, I masturbated to images of Grandma Irene's upskirt views, panties and big tits... and the earlier episode with her stuck zipper.

BUT I still felt their presence and couldn't do it freely, thus, I felt good taking my time for a long, slow session, I just couldn't build up head of steam to reach the critical boiling point. I was too conscious my hand movements would be noticed.

Frustrated, I fell asleep holding my hard dick.

It wasn't a surprise I had erotic dreams. Dreams are crazy things, they usually play with scenarios that are surreal, far from reality. Tonight was a case in point. In my dream I heard my bed creaking, making strange noises that I'd never heard my bed make. Looking towards the bed I saw grandfather on top of grandmother, his arse rising and falling. THEY WERE FUCKING!

The shock woke me up and I opened my eyes startled. But... but the rhythmic noise was still present. Quickly, I turned around to investigate... and... and... it was true! There, in almost a silhouette, was my grandpa, fucking grandma!! This was incredible. It blew my mind. For one, aren't they too old to fuck? I didn't think they'd still be doing it at their age! I watched transfixed, disbelieving my eyes!

My hand automatically went to my now hard cock. I masturbated watching a live fucking porno show. On my bed my grandparents were fucking.

My hand began to move faster, encouraged by the louder noises from the bed, masking the sounds I was making. BUT...

"UNGH!"

Damn, is that grandpa cumming? Coming in grandma?

Abruptly, the noises ceased. My grandparents stopped moving. FUCK! That was unbelievable. Did I just witness that?

However, that left me holding my erection in my hand. Throbbing, sensitive, and achingly hard. If anything, what I saw showed my movements would be seen. Hence, all I could do was rhythmically squeeze my hard cock as I replayed what I had seen. I couldn't stroke fast enough to trigger my own release. And so, I fell asleep, once again frustrated... with my cock in my hand.

------

Day 6 -- Thursday

It was in the morning that I was able to quickly jerk off... to the memory of last night. And seeing up her nightie as she had got out of bed, it provided even more visual stimuli.

At breakfast, I couldn't stop looking at my grandparents. I saw them in a different light, no longer old but amazed that they still fucked... that I actually SAW them fucking.

All day at school I kept getting flashbacks of my grandparents fucking. So much so that I just HAD to take a few minutes during a break to jerk off in the school toilet cubicle.

**

Grandma flashed me her navy blue panties that evening, before I was in bed gently stroking my hard cock, wondering if my grandparents were going to fuck again tonight. Alas, I didn't see them doing it before I dozed off; but I did have one of those crazy, erotic dreams. I dreamt my cock was getting sucked. I had wondered what it would feel like after some of the boys at school had boasted about their experiences. Some even bragged about cumming in the girl's mouth! Now, I didn't really believe that.

In my dream I luxuriated in the wet, soft, warm feeling of the mouth, wondering if it really did feel like this in real life. I wondered if grandma sucked grandpa's cock. Then my mind wondered off to mum and Bella, wondering if they also sucked cock?

It was feeling really good, I had to grab my cock and give it a good wank. Dreamily I reached out but stopped. I felt hair... and head. With a start, I opened my eyes and stared at a confusing sight. Someone was bobbing their head... GRANDMA! No way! Grandma Irene was actually sucking my cock!

She looked up, put her finger to her lips and returned my cock back in her mouth. It was too much. I was already so high that I immediately went over the top. I frantically tried to warn her with desperate groans, but I came, blasting my cum in my grandmother's mouth. For a moment nothing else mattered but just to enjoy the glorious feeling of my eruptions and the incredible, earth-shattering thought that I was filling my grandmother's mouth with my cum. I pursued my lips, desperately trying not to make a sound.

"There, I hope that helps," she whispered conspiratively. "Now, good night."

Slowly coming down, I didn't know what hit me as my eyes followed Grandma Irene back to her bed. She did nothing to hide giving me a flash up her nightie as she climbed back into the bed. I was thankful that Grandpa Pedro remained asleep!

------

Day 7 -- Friday

The next day at breakfast I couldn't help staring at my grandmother of 65. Did she really suck my cock? She simply said hello to everyone and acted as if nothing unusual, erotic had happened last night. She didn't even give me any acknowledging meaningful looks. It must have been my imagination, just a dream.

At school I keenly looked at all the boys in my class and wondered how many of them had their cocks sucked. I didn't have the courage to ask. Some of the louder boys boasted, but at 18, I wondered if it was really true. But then again, at 18, I got a blowjob from my grandmother... at least it felt real!

**

At home, grandma again invariably found a way to flash me her panties. But today they looked different. I didn't get a good look up her skirt, but they looked like light purple, lilac maybe; satin?

I was beginning to wonder if it was me, just lucky enough to be in the right place at the right time or was Grandma Irene getting careless or unaware in her old age that she's flashing her panties, just like young girls are.

And about last night, I wanted her to say something, just to acknowledge that she did do it and I wasn't mad or didn't dream it. But nothing.

Alone in my room where it happened, trying hard to concentrate on doing my homework, another strange thing happened.

Grandma came to the room, closed the door and said: "Rick, honey, can you be a dear and help me?"

"Sure, grandma. What's up?" I asked, looking her way. "Wow, you look great!" Mum was taking her out to meet some of her friends, a girls' Friday night out.

"My suspender has come undone. Can you re-attach it for me, please? It's the front one on the right leg. I've just painted my nails."

I blinked and stared at her like if she was mad. What do I know about suspenders? She was wearing a very fetching, low-cut black dress fitting her tightly above her waist, accentuating her wonderful curves, especially her large breasts. From the waist down, the dress flared out slightly, reaching just above her knees. And the legs looked ever so sexy covered with black stockings. She looked stunning.

Yes, the right leg's stocking looked loose.

"Please," she prompted again when I didn't move, and slid next to me, leaning against my desk. I guess she would have asked her husband, but he was again out with dad. But why not ask my mum, or sister, if she's home?

Taking a deep breath, I got off my chair and knelt in front of her, unsure how to begin, how to do this. I've never had any dealings with stockings and suspenders, for God's sake. Should I lift her dress? Should I slide my hand up her thigh to search for the suspender? I looked up at her for guidance. "I don't know...," I pleaded pathetically.

"You'll work it out," she unhelpfully offered dismissively, before going back to blowing on her nails, leaving me to decide. I chose the latter.

Taking a deep breath again, I gingerly placed my right hand on her right thigh. The initial contact was electric. The feel of the nylon and her thigh, it seemed so intimate and taboo -- maybe I should've gone for lifting her dress. But she didn't flinch, so I slid my hand up, under her dress; kept going, past the top of the loose stocking, touching her bare thigh. My heart raced at the touch of her warm, smooth skin so far up under her dress. I expected her to stop me any second now for being impudent and going too far up. But nothing again.

This was crazy, my heart was thumping. I mean, under normal circumstances, when would you imagine you'd be sliding your hand up your grandmother's dress?

I knew what I was searching for; I'd seen pictures. But it seemed... ah, I finally grabbed it. Pulling it down, I tried to attach it to the stocking leg, but with one hand, and blindly, it was impossible. When I decided to utilize my other hand as well, she seemed to move to adjust her posture, and the suspender slipped from my fingers, springing back up. I cursed my luck.

Back I went searching again, sliding my hand up the extremely erotic warm, smooth and chunky soft upper thigh, expecting any second to touch the elasticated leg of her panties. But no, instead, my hand encountered loose, lacy, sleek material, allowing my hand to easily slip under it. For a moment confusion etched across my face wondering what was going on under there? But in a flash I guessed that Grandma Irene was wearing French knickers today! I hadn't seen them in my search of her suitcase, so she must have bought them on yesterday's shopping trip with mum.

I quickly glanced up to seek help, but found she was still nonchalantly tending to her nails. So, it was up to me.

My legs were hurting a bit now, so I used my left hand for balance, placing it on the back of her thigh, before shakily continuing my foray inside my grandmother's underwear! Just the thought made my head spin.

There! I thought I found the offending elasticated suspender, feeling it with my little finger. Turning my hand to my right I searched but... but it was not the suspender... it was hair... pussy hair!

I stopped dead, fearful, awaiting sharp rebuke for my indiscretion and further impedance for straying off course. But nothing. She must know I was touching her pussy hair. But she said nothing. Emboldened, and out of curiosity and some unknown force, my hand veered further to the right, combing my fingers in the... wow, it felt like a forest! I was fascinated! Most of the dirty pictures I had seen had the women shaved down there.

I went further, all out feeling up my grandmother's pussy, the loose French knickers affording me easy access. Suddenly I realized my left hand was on her arse, again inside her underwear; somehow it had traveled on its own volition. For a moment I concentrated on that hand, feeling the amazing smooth, large expanse, letting my hand travel all over the roundness.

Yes, my hands freely felt up Grandma Irene's pussy and arse, fascinated at touching someone so intimately; all pretence of searching for the lost suspender gone. I even went between her thighs... did she part her legs a bit more?

I didn't look up, I dared not, I just let my hands do the searching and feeling under her dress and inside her knickers; my eyes glued to the front of her dress, rapturously watching the movements caused by the actions underneath. I didn't ask why I was allowed to get this far, the question didn't occur to me, I was too embroiled in the crazy moment.

I don't know what kind of force driving me, but from somewhere I found courage to enter a finger. The area was wet but still I was amazed how quickly my finger slid in. Then two fingers. Somehow, I just knew I had to pump my hand, effectively fucking her with my fingers.

I heard heavy breathing, but I didn't stop. Faster. Faster. FASTER!

"Ooohh!" came a gasp from above my head.

Instinctively looking up, I saw her. Saw her face, looking as if in pain: eyes tightly shut, mouth open; leaning back against my desk, her hands holding her up.

Somehow, I knew it was time to extract my hands, unsure what her reaction was going to be, what she was going to say. I waited with dread. But the moment had passed as far as she was concerned. "Thank you," she said surprisingly, and moved away from my desk.

Thank you? Thank you?! But I still hadn't attached her suspender. I got up disappointed, unsure what had just happened, but feeling horny as hell. "But... but..." I stuttered confusingly since I hadn't managed to do up the suspender.

"Oh! Yes, of course. OK," she said, looking at the front of my pants. Seeing the obvious tenting and coming to some conclusion on her own, she took a step back towards me, saying: "But you have to be quick. Your mother might be almost ready."

I wondered what she was talking about.

But as I looked on dumbstruck, she deftly unzipped me and swiftly lowered my pants and underwear. Lifting up her dress, and with her legs far apart, pulling her panties aside -- yes, lilac French knickers -- she pulled me to her and expertly guided my rampant cock into her pussy.

Holy fucking sweet Jesus! Was my cock in my grandmother's pussy? Did she just put my cock in her pussy?

"Go ahead. But be quick," she simply instructed, belieing the precipice of a momentous act that we were on verge of committing, before once again resting herself against my desk, arms behind her, with me standing between her parted legs, joined to her.

For a moment I just stood bewildered. Was she telling me to FUCK her?

Damn, she was leaving it up to me! FUCK! I'd never done this before. What the fuck do I know about fucking? And doing it standing up? But if I wanted it, I'd have to work it out and take it myself, doing all the work.

Tentatively holding her by the waist, I just randomly pushed. Shoved. An 18year old virgin novice, completely out of my depth, against an expert, an accomplished mature woman who had fucked for years. She would have had a lot of fucking experience in her 65 years.

Resting my chin on her shoulders, I wrapped my arms around her and now held her tightly - she felt magnificent, big, soft and cuddly -- and went at her: shove, shove, shove. My dick seemed to know what it wanted.

Just like she wanted, I didn't last long and let loose in a torrent of jetting streams of cum, filling her pussy. Again and again my cock pulsated shooting more and more cum, totally draining me.

I collapsed onto my bed, breathing hard, feeling a million emotions, but ultimately feeling on top of the world.

With the corner of my eyes, still half dazed, I saw Grandma Irene lift up her dress, reach inside the leg of her lilac French knickers to pull out the errant suspender and effortlessly attach the stocking before smoothing out the dress.

"I'll just go to the loo to tidy up down there. Young man, you've come a lot; you youngsters always do. So much more than Pedro nowadays." Saying that, she was gone, closing the door behind her.

As I pulled up my gear, what she said echoed around my head and puzzled me. You youngsters always do? But I was too sapped of energy to think and zonked out for a few seconds before waking up disoriented, wondering where I was, what happened and why was I lying down?

But of course, the incident came flooding back. Did that really happen? Did I really have my cock in my grandmother's pussy? Did I really fuck my own grandmother? Did I just have my first fuck and lose my virginity? FUCK! Did I really cum in Grandma Irene's pussy?!

I couldn't move; I just replayed the most momentous event of my life. I had felt up her pussy! Looking at her, you'd never guess she had a really hairy pussy. AND I HAD MY FINGERS IN HER PUSSY! I had finger fucked my grandmother! FUCK! It felt so wet in there. Never did I imagine. And I fucked her. SHIT, man, I had stuck my cock in my Grandma Irene's cunt and FUCKED her! She let me. No, wait a minute, she encouraged me; she'd put my cock in her pussy herself. That confused me. She just stood back and let me fuck her.

And thinking these erotic thoughts had the expected effect. I unzipped myself and started to stroke my erect, throbbing cock. It felt great. It was still so sensitive. I lost myself in the revelling.

"Rick, we're leaving now... oh, I'm sorry," Grandma Irene said, bursting into my room. I quickly covered my cock with both my hands. A rather comical attempt. "Your mother says, for dinner eat what's in the fridge," she said, making eye contact. Then, looking at my pathetic attempt at hiding my cock, she added: "I'm, sorry. Carry on. Don't let me interrupt you." And closing the door, she was gone again.

I did it twice, thinking how ironic that I got to feel up and fuck my grandmother - who I effectively have only really known for a few days - when I'd been trying to touch my girlfriend's tits and get my hand up her skirt, with no luck. In two months, all I got was just a quick, teasing peck on the lips so far! OK, maybe that's because she's not really my girlfriend... yet... I just like to think she is.

**

By the time they all came back, I was asleep, but my grandparents' entrance into my room woke me up. But I remained motionless and kept my eyes closed. I guess thinking I was still asleep, without turning the light on, they decided to quietly undress right there and then in the darkness, unaware that I was actually peeking.

It was such an erotic display of striptease, I watched enthralled. Taking off her dress, in the dim light Grandma Irene stood like a picture of an oversized model in her lilac bra and matching French knickers, and black stockings. Then one by one she took off ALL her clothing to stand stark naked.

HOLY FUCK! Grandma Irene totally naked?! She looked fantastically curvy. Her tits big and bouncy as she moved, her arse nice and large and round, and the awesome dark patch between her legs. I had touched that hairy bush... even had my fingers and cock in there!

I didn't pay too much attention to Grandpa Pedro as he also stripped naked, but I couldn't help catch a glimpse of his swinging cock and balls.

Were they going to sleep naked today? That was answered when both my grandparents quietly got on the bed and started kissing... before I got a huge shock seeing Grandma Irene sucking her husband's cock. Then it hit me. They were going to fuck! And sure enough, as soon as the cock was hard, Grandpa Pedro sucked on his wife's tits and climbed on top of her. It was fucking crazy seeing my grandparents naked and fucking again! I couldn't believe they were doing it with me in the room!

They weren't making too much noise -- I suspect if they were alone, they'd be grunting and groaning loudly -- but they couldn't do much about the mattress and the bed creaking and squeaking.

I, of course, had my stiff cock in my hand as I watched the live porno show, timing and reaching my climax at the same time as they did. Afterwards, I left my wet tissue by my mattress, but when I woke up in the morning it had mysteriously vanished.

Day 8 -- Saturday

In the morning, it was awkward for me. They came down late, as I was leaving for school -- Saturday morning extra soccer practice - but I couldn't help staring at Grandma Irene and seeing her naked, as if I had x-ray eyes. Now I knew what she looked like totally naked. That was a deep, weird thought. Fuck, I even felt and saw her pussy... and I had fucked her. Shit, man, I had fucked my grandmother!!

I was dying to tell someone at school, my girlfriend even, but I knew I shouldn't. But yeah, that would be sweet seeing my "girlfriend's" face if I told her; the girlfriend that wouldn't even let me kiss her or touch her tits.

**

At home, Grandma Irene contrived to flash me her cleavage and her panties as usual... but now, when she caught me looking, she smiled and blatantly spread her legs a bit, giving me a better look. That made me suspicious that all this time she may have been giving me look up her skirts/dresses and down her tops on purpose(?)

I wanted to speak with her, I wanted her to explain about last night, but she basically behaved like usual, making no attempt to take me aside for a chat. I made overtures but basically I was shit scared to bring up the subject myself.

**

That night I pretended to fall asleep quickly but stayed alert listening, wondering if my grandparents were going to fuck again; I wondered if Grandpa Pedro could manage two days in a row at his age.

But I fell asleep, only to dream again Grandma Irene giving me a blowjob. Blowjob! I woke up with a start and looked down to see it was NOT a dream again. HOLY FUCK! Grandma really WAS giving me a blowjob again. What's more... she was NAKED!

I lay back staring, trying to comprehend the situation, but the next thing I knew was that she was lying alongside me; her body pressed against mine.

"Hello, handsome," she said. "Did I wake you?" But before I could reply, her mouth was on mine, and her hands were stripping my night clothes. I didn't move; I was stunned into submission.

"My, you're real hard tonight," she said, momentarily breaking the kiss and purposefully stroking my rigid pole, before returning to the wet mouth lock.

It was electric to be kissing her and be skin to skin, feeling her soft naked body against mine, her plump heavy leg on my leg, her big heavy breasts pressed up against my shoulder and chest... all the time she was slowly pumping me.

"Come," she said and rolled onto her back, pulling me on top of her. It was the strangest and the most intimate contact I could imagine. It was SO erotic lying naked on top of my grandmother, feeling every inch of her naked skin against mine. For a moment she just cradled me, in a soft body embrace, and I was actually aware of her hot body contrasting against the cool air of the room caressing my back.

"It's time," she said and reaching in between us, guided me into her pussy. "Go ahead, Rick, fuck me," she whispered in my ear; words I never would have imagined I'd ever hear my grandmother say to me.

This was it. Tentatively I started to move, afraid of doing it wrongly; some exploratively haphazard thrusts into her cunt. It felt simply divine. My cock approvingly recognized the receptacle, getting harder than I could remember. I huffed and puffed rapidly for all of 30 seconds before opening the flood gates. I didn't last long before I filled my grandmother's cunt with my semen.

"Ssh. It's OK. This always happens with you youngsters," she said enigmatically, stroking my back and running her hands over my arse cheeks to feel me up. "Next time it will be longer."

I was too dazed to register what she actually meant. But I remained elevated in my arousal; and slowly but surely my erection returned whilst still engulfed by my grandma's warm, wet pussy, aided by her kissing, touching, dirty talk, and her expert movements of her body. My cock knew what it wanted, it was in charge. Without me consciously deciding my hips began to move, sliding my rampant cock into and out of that warm cunt.

"That's it. See?" grandma said. "You can fuck me again."

And I did! I speeded up, doing different moves. This time grandma wrapped her arms and legs around me, trapping me with her body in a soft cocoon and joined in the fucking. My world consisted of only my grandmother and me, just fucking.

"Ohh, yes, this is why you kids are the best," she cooed softly. "Harder," she urged.

I did! I speeded up and fucked her as hard as my youthful body could manage. And when it came it was the most glorious orgasm yet.

"Yes, this is it. This is the best," she gasped in my ear, also enjoying her own climax.

It was only after I rolled off Grandma Irene and saw the bed that I worried about grandpa. Did he hear us? Did he see? But miraculously he was apparently still asleep.

Grandma put her nightie on and went to the loo to clean up my double load. Now feeling the cool air, I put my pyjamas back on, covered up and turned on to my side to sleep, wondering how can she be so audacious with her husband right there in the same room? But more pointedly, why me, when her husband was right there to provide the marital service?

------

Day 9 -- Sunday

My parents went off with my grandparents for a day out, so nothing much happened during the day, not even the usual upskirt from my grandmother. It was the first day since she arrived that I didn't get to look up her skirt. So today, I didn't know what panties she was wearing!

And no chance to talk with her.

But Fuck! That night was just the same. I fucked grandma twice. After the fucking, whilst we were recovering, she finally explained in hush tones, that Grandpa Pedro, at his age and with something about familiarity, can't get it up easily with her, so they only fucked occasionally, even if she wanted to do it more often. That's why she was using me. Besides, she enjoyed fucking with teenagers.

Then it hit me, she'd mentioned teenagers a few times, I wondered how many teenagers she'd fucked? She's done this before? Cheated on her husband before?

"Ha... have you done it with... many teenagers?" I asked cautiously in a whisper.

She regarded me keenly before answering, probably wondering if it was safe to answer. "Yes, many in my global travels. Each country has different rules, but teenagers like you the world over are just the same: eager to fuck and can do it multiple times."

But then she's been cheating on grandpa, on her husband, for a long time?! I mean, I was feeling a bit guilty of fucking grandma, but she's just confessed to doing it with countless teenagers. And maybe others... non-teenagers as well! Holy shit!

Whilst we had talked, she had her hand between my legs, playing with my cock and balls, and I fondled and sucked her big tits; finally getting my hands and mouth on those amazing things. Invariably, I became stiff once again.

"You see?" she chuckled and pulled me on top of her once again.

We joyously fucked for the third time that night, a much slower, explorative experience. Whereas previously I just wildly shoved it in, this time I concentrated on the sensations my cock was feeling: the wet, all engulfing, gripping sensation. It simply felt great to slide my steel-hard stiff cock in my grandmother's pussy, and then to slide it out. I even became aware of our pubes mashing, the soft cushioning effect of her bushy growth melding with my own pubic hair.

But when she rolled us around and she was on top, it was a shock. It felt so different to be under her greater weight! All that warm, soft flesh... and her big tits hanging down, swinging in my face. I came ever so quickly with the surprising novel experience.

"Thank you," she said, and hopped back into bed.

Thank you? Thank you? She was thanking ME? It's thank YOU, ma'am I thought, but I couldn't voice my thoughts.

**

As I was drifting off to sleep the bedroom door slowly opened and in walked my grandfather! Where the hell had he been? I didn't even realize he wasn't in the bed all this time!!

------

Days 10 to 14 -- Monday to Friday

The rest of the week followed a similar pattern to the previous weekdays. I got peeks of Grandma Irene's panties -- now she deliberately and overtly spread her legs or lifted a leg, giving me a good look. When no one was looking, she'd even snog me, pressing me to her body and grabbed my junk to teasingly make me hard. And at nights we fucked... EVERY night!

Not only fuck, but she also taught me how to suck... and even lightly bite!... her nipples. And how to finger and lick her pussy. It was an incredible learning experience to have Grandma Irene lay back naked, allowing me to explore every inch of her big nude body.

But curiously on some of the nights Grandpa Pedro left the room, to return about 30 to 45mins later! In that time grandma and I fucked and she taught me different positions. But I was fearful we may be caught on his return if we didn't finish on time, but grandma didn't seem to be as concerned, she seemed confident we'd finish our fuck before he returned. (On the days when he didn't leave the room, grandma waited until her husband was asleep before joining me... literally.)

"Where did grandpa go?" I asked one night. "Is he alright?"

"Ssh, don't worry about him. He's alright," she replied before returning to sucking my cock.

It was on this day that she got me to return the favor and put my mouth on her pussy. That was a very unusual experience to be trapped between two meaty thighs, the hair tickling my nose... and the taste and the smell! It was on this day I got my first good look at a pussy, to find out first-hand what a woman looks like down there.

------

Day 15 -- Saturday

But the biggest shock was on the Saturday night, after everyone had gone to sleep... sort of. Grandpa had gone walkabout and grandma and I were busy doing '69'.

With me suitably excited and ready to plunge my cock into Grandma Irene, she said: "Put your pyjamas on and come with me."

"What? But... aren't we...?" My cock was straining and ready to go, for fuck sake! "Where are we going?"

"Just follow me," she said enigmatically, draping herself with just her nightie -- she didn't put her black panties on.

I did as she asked, but my erect cock of course poked out of the flies like a curious snake, investigating its surroundings. I thought we were going for some kinky, clothed sex, but she took my hand and lead me out of my room -- mindful of closing my door.

Each step we took I tried to guess where we were headed. Did she want to fuck in the front room? The kitchen? Even outside?! Too cold for that, especially in our thin night clothes.

But curiously, we stopped outside a door. Grandma turned the handle and we walked in, before closing the door. For a second we stood still. Me? I froze solid, my eyes wide in disbelief.

All my previous questions were answered right there... but new ones formed also.

We were in... my sister Bella's bedroom. On her bed were two people... naked. One young woman, the other an old man. Lights were not on, but we were able to see the movements as our eyes were already acclimatized to the darkness; and we heard the creaking bed.

JESUS FUCKING CHRIST!

Grandpa Pedro was fucking my sister!!

My loud gasp turned the faces of the naked mating couple.

"WHAT?!" came the loud shout from my sister, before shouting: "GET OUT! GET OUT!" It was an odd shout. It was loud, but strained, more like a loud whisper.

I wasn't sure if the request(!) was only directed at me or also at our grandma.

"It's OK," Grandpa Pedro said calmly, temporarily halting his thrusting.

What? He wasn't troubled by being caught out by his wife?!

"It's OK," Grandma Irene said, putting up a reassuring palm to calm Bella.

And grandma wasn't troubled by catching her husband in the act?!

Bella wasn't convinced; she wriggled and squirmed, trying to push grandpa off her and was looking to cover up. But he resisted, keeping his weight on her and holding onto her, ensuring his cock remained firmly lodged in her pussy.

"It's OK, Bella," grandma said again in her most soothing tone as she now took steps towards the bed, pulling me along. But what really shut Bella up and stopped her trying to wriggle free from under grandpa, was the sight of Grandma Irene pulling off her nightie and standing naked next to her. "You too," grandma said to me. "Do it," she said firmly when I didn't move, obviously feeling confused and bewildered.

It was only then, with me standing so close, that my sister noticed the 'inquisitive snake' still poking out.

"RICK!" she gasped loudly, pointing towards my flies and looking up at me before looking down again, unable to resist taking another look at my erect cock. But her gasp grew louder, and her eyes widened when I also stripped in front of her and grandpa.

Hey, this isn't real, is it? It's an alternate reality in a surreal dream where anything goes. I felt as if I was being driven by forces beyond my control.

Yeah, grandpa. He was watching the commotion, but his arse was still moving. So, all this time he was leaving the room at night - when grandma was fucking me - grandpa was here, fucking my sister?! No wonder grandma seemed unconcerned, and how she got away with fucking so many other boys and men, as she had claimed. He knew. Moreover, Grandpa Pedro must have equally been out fucking teenage girls and other women! FUCK!!! What an arrangement between them!

But why was I here? Why did Grandma Irene bring me to my sister's room...? And why are we now naked?

My thoughts were interrupted by my squeak. I looked down to find grandma had got hold of my (admittedly softening) cock and was stroking it... in front of her onlooking husband and my sister! But then, without batting an eyelid, she was on her knees with my cock in her mouth.

Holy shit! I looked up to catch my sister's eyes and exchanged strange looks as both of us were being... well, sexually engaged by our grandparents. I was afraid to look at grandpa, afraid that he'd somehow accuse me of defiling his wife.

And when grandma got on all fours on the floor, she invited me behind her. Initially I was confused, showing my naivety, but soon understood. Now I did look grandpa in the eyes. After all, I was about to put my stiff cock in his wife's pussy... whilst he watched! Did I see him give a nod of approval? He did stop fucking my sister for a while to look. Both him and my sister were watching... expectantly.

I was WAY out of my league here. With uncertainty I did grandma's bidding and entered her from behind and heard grandma groan. Holding her by her hips I did what came naturally. Fucking hell, I was fucking my grandmother whilst being watched by her husband and my sister, and with my parents sleeping just down the corridor! THIS had to be a dream.

I guess watching us fucking re-ignited my grandfather's fire, for he presently resumed his poking of my sister. She in turn now fully engaged with grandpa, wrapping her arms and legs around him, encouraging him, thrusting up at him. I'd never seen my sister like this before, thus I stopped what I was doing to watch them.

All of a sudden, the room flooded with soft light... grandma had reached up and put the bedside lamp on! Actually, it was only a small lamp, it was just the suddenness that made it look brighter than it really was. But the two on the bed did not seem to notice, they were so far into their act... and I was enthralled at the now much clearer sight of two naked people fucking.

"Ahem!" grandma coughed, reminding me of my duty.

So, here we were, brother and sister fucking our grandparents. My mother asleep, oblivious that her parents were fucking her children!

All of a sudden, even as I was approaching my peak, grandma pulled away.

"Huh? But...?" I protested, trying to crawl back into her.

"N... No, no! Wait...! Nearly...!" I heard my sister protest. I turned to see grandpa disengage from my sister and get off the bed; at the same time grandma pulled me up and pushed me onto the bed. I tell you, it's a weird sight seeing another man's erection so close in person. To see my grandfather's hard, wet cock jutting from his hairy bush... it... it was captivating. The power it portrayed! And that thing was IN my sister's cunt!

But my eyes quickly turned to my supine sister. My life recently has been one surprise or shock after another. Now it was seeing my sister of 21 totally naked for the first time. My eyes rapidly scanned all over her body, afraid she'll cover up and I'd miss seeing some detail. Breasts: marvelous, belly: firm, legs: awesome, pussy: shaved.

After seeing my grandmother's extra hairy pussy, it was weird seeing a hairless pussy. Sure, I'd seen dirty pics of nude women with bare pussies, but seeing one in real life and able to see my sister's slit... that made my head spin.

"Get on the bed and lie on top of your sister," grandma instructed like it was no big deal.

"WHAT?!" Bella shouted, this time without restraint and slammed her legs shut. "No fucking way! He's not sticking that thing in me," she said unkindly, pointing to my impressive hard cock.

"Bella, I know you and your brother barely speak to each other, and when you do, you argue or bicker. That's no way for siblings to behave; no way family members should behave with each other," grandma said.

It was strange to see Grandma Irene give a lecture in the nude! She continued...

"Instead, we want you to enjoy each other's company. In our travels we've seen much unhappiness, but also great joy. And the one thing we've learnt above all is sex... sex brings great joy."

"Yes, it's the ultimate expression of joy. Wherever we see disputes, etc., we get them to fuck," grandpa chipped in crudely. "And whoever we stay with -- and we've stayed with many, many welcoming strangers -- we thank them with sex."

"You have sex with all the people you stay with?" Bella asked with incredulity.

"Well, not ALL, but yes, most," Grandma Irene clarified. Then she went on to tells us stories about how they got some brothers and sisters -- and husbands and wives - back together again by encouraging them to have sex with each other.

Bella and I listened spellbound, but the whole scenario was just crazy. My sister and I were naked and getting a sermon from our equally naked grandparents!

"Bella, you also like sex, you love it, else you wouldn't be fucking your grandfather," said grandma pointedly. "Think how much readily available your brother is, right here at home. You could fuck every night."

And whilst my sister contemplated that incredible scenario, grandpa pushed me to mount my sister.

The feeling of my sister's naked body against mine was simply electric. Bella snapped back to the present, and we both stared at each other.

"Open your legs, Bella," grandma instructed, pulling on one of her ankles. "Wouldn't you rather fuck than fight with your brother?"

To my surprise Bella obeyed and just like that my pulsating rod was pressed against my sister's pussy. We both continued to stare at each other, feeling somewhat dazed, being swept along by our amazing, naked grandparents.

And when I felt a hand in between my thighs grabbing my cock there was a mild shock, but I parted my legs to allow the hand greater access, consequently pushing my sister's legs further apart. And when that hand guided my cock to my sister's vagina, I did what came naturally and thrust my hips. With my stiff, pulsating cock buried deep in my sister's pussy I continued to stare at her, seeing her flinch at my sudden sharp penetration.

We were now so deep in a zone that I didn't even hear my grandparents speaking, who were encouraging us to fuck. I hadn't even realized that it was my grandfather who had my cock in his hand and directed it to Bella's pussy!

It was just my sister and me; we started to fuck looking at each other, completely zoned out with the newness of the erotic tabooness. And without any prompting from anybody we kissed, a tentative peck first, but then we were kissing and fucking like crazy, utilizing our youthful energy to the max, as if our lives depended on it. Me at mere 18 was fucking my 21year old sister.

With the prolonged build up and the tabooness of it all, our climaxes were out of this world with me depositing copious amounts of my cum inside my sister's cunt. But we fucked and grunted right through them... and continued even after, immediately searching for our next orgasm.

Knowing someone all my life, and now I was fucking her... it was mind-blowing. I went wild with my pumping. And my sister loved it, for she thrust back up equally energetically.

We were oblivious to what our grandparents were saying and doing. It wasn't until we began to come down from our second climax that we heard grunting from the floor. Both of us turned our heads to see our grandparents locked in a naked embrace... and fucking!

"Come on Pedro, harder!" our 65year old grandma was saying. "Yes, baby, fuck me, fuck me!"

With the table lamp on, we could clearly see their naked bodies moving. It was an awesome sight; a much better view than what I saw in the near darkness in my room. It was odd seeing such old people fucking.

After they had their orgasms, we left my sister's room to return to my room. But before we left Grandma Irene spoke some words of wisdom for our benefit:

"Now, wasn't that better? Isn't fucking better then arguing?"

------

Days 16 to 20 -- Sunday to Thursday

Oddly, on the Sunday it seemed Bella might have been having regrets about last night because she was avoiding me.

Grandma Irene noticed and told me: "Don't worry, I'm sure things will be alright. I'll have a word with her."

Then Bella went out straight after lunch, not to return until late. And I didn't see her for breakfast on Monday morning.

But it was on this day, when Bella returned from her university, that I got a shock of my life.

"Do you wanna fuck?" she whispered in my ear. "Come up to my room if you do."

For a moment I didn't move, not believing my ears. It was not like her to be so accommodating; so much out of character. But recovering, I raced up to her room just in case. But once I entered the room I froze again. Now what? I'd never really made a move on a girl, not even my "girlfriend"; it's been grandma directing things.

"Shut the door, unless you want everyone to see," Bella instructed.

I did... then, again I stood still, unsure what to do next, not being versed in the art of seduction. I blinked several times, hoping my sister will make the first move. And she did!

I could tell she was experienced, after all she had a boyfriend until recently; she'd had several boyfriends over the years. She started by kissing me, full, wet, mouth-invading kiss; not a kiss normally given by a sister to a brother. And whilst she kissed her hand found itself inside my briefs and pulled out my cock and masturbated me to hardness. Firmly holding my cock, she tugged me to her bed and had sex with me.

We didn't say much, just fucked. Yes, she basically fucked me to satisfy her needs, and I mostly went along for the (enjoyable!) ride. I think she was just as turned on by the fact that she was fucking her brother as I was about fucking my sister.

"That's good to see," came a voice from the door whilst we were in the middle of it. It was our grandma! "Don't worry, we'll keep your parents busy," she said, and she was gone.

------

Over the rest of the week my sister and I fucked as much as we could, aided by our grandparents keeping our parents busy. But at nights all four of us got together either in my room or my sister's room for a night of 4-way fucking before retiring to sleep. Whatever reservation or second thoughts my sister had about having sex with me, her brother, seemed to have disappeared!

It was quite an education for both of us siblings to learn from the hugely experienced grandparents; from sucking, licking and fucking different ways and, yes, fucking in the arse. THAT was an eye-opener, to stick my dick in my sister's and grandma's arse; and watch grandpa do the same to the two ladies. Even for my sister that was new; she'd never done that with her boyfriends.

And during the course of the nights of fucking our grandparents were moved to share more stories of their sexual encounters and exploits to spice up our sessions.

We of course had to be careful not to make too much noise that could attract our parents.

Day 21 -- Friday

But it was on the final night of our grandparents' stay that I got one more shock I never thought I'd ever experience. In my room, the night started out normally enough -- well, normal by recent activities! -- with us four stripping naked and Grandma Irene getting me on my back and latching onto my mouth for a full-on deep kiss to get things going. Then a hand grabbed my cock, which was not a great surprise. BUT this felt different. It didn't feel like grandma's, nor Bella's soft hand. I was confused, so I pushed grandma aside to have a look.

I was stunned to find Grandpa Pedro holding AND stroking my cock, trying to get me hard! I quickly looked at grandma, who gave me a sly grin, then back to grandpa, who also smiled at me.

It felt strange, his hand felt different to when my sister or grandma... or even when I held it. Grandpa of course had his own style when he masturbated himself, and he was applying that to my cock!

I love having my dick stroked, but having it done by a guy... my own grandfather! That scrambled my head but somehow elevated my arousal in a different way. But that was nothing compared to what was to follow.

"Don't worry, Rick, honey, you're not the first," Grandma Irene said casually. "Remember, we've traveled the world seeing and doing lots of things. Including this..."

She took hold of my hand and guided it to Grandpa Pedro's cock, wrapping my fingers around the semi-hard member and encouraged me to masturbate her husband.

Instantly strange, unexplainable emotions and sensations swirled around my head and body. My hand recognized that it was holding a familiar item, a cock, but at the same time it felt strangely unfamiliar. And previously, having only ever held my own cock, my brain couldn't come to terms with the lack of expected corresponding sensations from my cock.

Yes, it felt weird but also exciting to be holding someone else's cock; to be holding my grandfather so intimately.

It was like a stage fright, I just held the unfamiliar penis, thus grandma wrapped her hand around mine and reminded me to move my hand up and down, like teaching a novice how to masturbate a cock.

Having got grandfather and me mutually masturbating, Grandma Irene turned around and playfully wrestled my sister onto her back, attacking her with kisses on her mouth and all over her body, sucking those young, firm tits, before ending up with her head between my sister's legs.

Astonishingly, as Grandpa Pedro was sucking my cock -- yes, now sucking my cock! -- Grandma Irene was licking and orally stimulating my sister's pussy!

Bella and I looked at each other, speechless. Both our grandparents had their mouths on us whilst we duly masturbated them! (Grandma had guided Bella's fingers into her hairy pussy.) Just like I hadn't previously sexually fooled around with a boy before, from the look on Bella's face it didn't seem like she had been with a girl.

All this was overloading my senses, and my cock was stiff as a metal pole, getting ready to blow. I shockingly wondered if grandpa was going to... but just then, as if sensing my predicament, he stopped and moved away, his equally stiff cock slipping from my grasp. I felt distraught; being so close to an incredible orgasm I almost wanted to plead with him to finish me off.

But like a well-practiced couple, in sync both our grandparents released us and swapped partners; Grandma Irene sucked my cock before impaling herself on me, and Grandpa Pedro penetrated my sister. As we were getting fucked by our grandparents, I couldn't help wondering how many times have they done this? How many times have they fucked siblings at the same time? The way grandpa played with my cock and sucked me, we certainly weren't the first.

This was too fantastic and I blew my load into Grandma Irene's pussy. And hearing Bella's muffled scream and Grandpa Pedro's groans, they also reached their peaks.

With both our grandparents slumped on the carpet recovering, I was still way too horny; after all this was a night like no other. I crawled over to my sister and put my cock in her mouth to get me fully hard, she didn't object; then I entered her pussy. As I fucked her, I reflected on the tonight, and the fact that I had my cock sucked by THREE different people tonight: two women... and one man! And I had held another guy's cock. What a sex education were our grandparents providing us with?

It was of note that whilst Grandma Irene and Grandpa Pedro recounted their adventures when our parents were around it was a different version at nights when they were alone with my sister and me. They gave us the sexual version. They told us about the sex they had with different kinds of people of various ages, sometimes involving ALL the members of the family they stayed with.

"As you might have guessed, you weren't the first boy for your grandfather," Grandma Irene said to me without any hint of concern, now feeling free to reveal that side of their sexual activities.

"And you weren't the first girl for your grandmother," Grandpa Pedro said to my sister. Touché!

My sister and I listened avidly to some of these kinds of wild stories. Now they felt free to confess that Grandpa Pedro had, indeed, had sex with other boys and men, and Grandma Irene did have sex with other girls and women all legally. These two old people really have lived life to the fullest, experiencing everything, it would seem. But I still felt we didn't get the full spiel; that they might have done other things in some far-off lands that they weren't telling us about.

After reminding us once again not to be silly and waste our young days bickering and fuck instead, we went to bed.

Day 22 -- Saturday

Today was the day my grandparents were due to depart, and they were already downstairs for breakfast, before me. As I was about to enter the kitchen, hearing what appeared to be an argument between my mother and her parents, I stopped in the hall, out of their eyesight, to eavesdrop for a second.

"You never helped your brothers, I had to take care of them -- both of them -- AND your father," Grandma Irene said.

"I told you, it's not right. Why are you interfering with my family?" mother shot back.

"Someone has to. Your poor kids are suffering. Kids their age need it; I know from experience. It's the same all around the world," grandma explained.

"How many teenagers have you and dad initiated? How many families have you interfered with?" mother asked.

"We don't know. Don't keep count, you know. Besides, each country has their own rules," grandpa replied.

At that point I entered the kitchen and the argument stopped.

"Good morning honey," my mother chirped, changing her tone for me.

"Good morning, all," I said, then I couldn't help but stare at my grandparents and see them naked and think about what I did with them last night... no, what they did to us, my sister and me!

It was a strange breakfast. They knew I was looking at them, but they just smiled back at me.

**

Finally, it was time for my grandparents to go. As they said goodbye, I saw grandpa grope mum and kiss her on the lips, and grandma do the same to dad.

Surely not, I thought, not with mum and dad! Did they?

Then they bid farewell to my sister and me in the same way, but grandma whispered in my ear: "Keep fucking your sister."

Epilogue

Surprisingly, after a few months, our grandparents returned to stay with us again, this time just for a week before they once again finally left the country for new adventures abroad. These past months, they had stayed with each of their other children, some of whom had grandchildren younger than us; others had grandchildren about our age or older. I wondered if they also got up to naughty things with those grandchildren?

The reason they gave our parents for their return was that we were their favorite grandchildren and didn't know when, or even IF they'd see us again. But it transpired that this time they had further ideas!

This time they had sex with Bella and me like I never imagined I'd ever would have. They said we don't have to do any of it ever again, but that it's good to experiment and experience new things at least once.

For a week they fucked us and used us in ways I find too embarrassing to mention and write about. Suffice to say at 18, I'm not going to be doing any of THOSE things any time soon to my girlfriend or any other girl I meet and who's willing to have sex with me... or to any guy I befriend!

Amen!

But I did progress with my girlfriend. We kissed and she let me grope her tits whilst I worked on getting her hand on my cock.

However, my sister and I did take our grandparents' advice and fucked regularly, especially on weekdays, and also on weekends when we weren't meeting up with our respective boyfriend/girlfriend.

That stopped when Bella got a distant job after she graduated and left the house. If my parents knew what we had been doing, they didn't let on or stop us.

By the time Bella left I thankfully graduated (haha) to getting my hand up my girlfriend's skirt and in her knickers, and getting her to suck my cock. But she didn't want to fuck before marriage. That was alright whilst Bella was around when I could fuck her. But now that she's gone I need to somehow persuade my girlfriend to open her legs for me.

Oh, by the way, my girlfriend has a hairy pussy, she's not into shaving down there, which is good news. I blame Grandma Irene for my stance on pussy hair.

A thought occurred to me about what mum had said initially, that the grandparents wanted to meet us now that my sister and I were grown up. But it seemed they actually wanted to fuck us, now that we were old enough to have sex! They were like a tornado. They came briefly, messed everything up, and left, leaving behind a new reality.

For instance, as a consequence of fucking together, I guess my sister and I were subsequently bickering less and talking to each other, so the house felt more joyful with less tension in the air. So, my parents probably decided not to interfere with our illicit activities and destroy the new good vibes in the house.

You know, I never did get to ask my sister why she let Grandpa Pedro fuck her, him being as old as 67; how he had persuaded her. Maybe I'll ask her next time we meet.

But you know what? Our relationship had improved so much that, after I had mentioned how much I had enjoyed playing about and combining my fingers through Grandma Irene's pussy hair, Bella actually let her own pussy hair grow for a while, just for me, just so I could see her in her natural hairy state! But, after a few weeks, she said she'd been shaving for so long that that's what she was used to and much preferred the clean look and, to my disappointment, she shaved if off again.

Me? I kept my pubic hair, and also told my girlfriend to never shave, except for essential tidying up, but only then if absolutely necessary! I blame Grandma Irene.
