Youth hosteling with my sister in law

[dooboob]

Of course my wife’s younger sister Jill had always been the subject of many delightful fantasies. Although sharing the same body type as Helen, Jill was perhaps a couple of stone lighter, certainly her breasts were smaller, but like her sister she had a pleasantly plump bottom, and no doubt thought her thighs were too big. I thought they were just great. Over the years I’d had glimpses of her “bits” – always “unintentional”, but there was definitely a frisson between us. I often helped her around the house, with the computer and such, and now husband Dean was no longer around, I often found myself roped in to fix things. And almost always Jill would somehow end up very close, helping me, and “accidentally” touching. On one memorable occasion I was cutting card with a craft knife for her, and she was holding the steel ruler for me. Her breast was pressed against my arm, maybe not deliberately, but neither of us made any move to break contact. Another time we were all together having breakfast, and I was helping her daughter with a puzzle on the floor. Jill was sitting next to Helen, and neither had dressed yet. While Helen was still in her pyjamas, Jill wore the nightshirt she slept in. When I glanced up, I was delighted to see she wore no knickers beneath the shirt. She was sitting behind the table, legs slightly apart, and her nicely hairy pussy fully visible. I’m sure she didn’t realise, at least not consciously, that she was giving me such an exclusive view. Exclusive because no one else was in the “firing line”. So it was with hopes of at least more tantalising glimpses that I found myself on a Youth Hostel holiday in Wales with Helen and our younger son, and Jill with her two children.
The hostel was a few hundred yards from the beach, and since none of us wanted to spend much time driving, we spent most of the holiday there, sunbathing, swimming in the somewhat chilly sea, and wandering along the beautiful rocky shore and the cliffs. This was the first time we’d been away with them since Dean’s departure, and what a difference! For the first time since her divorce Jill seemed to unwind properly, and even cut down her smoking to a couple of Silk Cuts a day. As ever Helen refused my polite advances in bed, always being “too tired”, or imploring me not to “spoil the mood” by “making an issue of it”. So I didn’t. In fact I didn’t even do much wanking, as that always riled Helen if she noticed, which she often did.
Although Helen and I had often been to naturist beaches, and both of us would go naked, Jill, while happy to expose her breasts, always kept her bikini bottoms on. We were all cool with this, though I think it embarrassed Dean a little. Anyway this beach was definitely textile, though none of us made much fuss changing into our swimwear, which once more afforded me of a few choice glimpses of Jill’s large nipples and her still splendidly hairy pussy.

A few days into the holiday, Josh, our younger son, had gone with Jill’s kids into town, leaving Helen, Jill and myself to the beach. Although by no means naturist, the quiet part we were in had few people, and some of the women were daring to go topless.
Helen had a fairly modest one-piece costume, though with cut away sides, which revealed her carefully waxed bikini line. However Jill had brought a splendidly skimpy Wicked Weasel bikini with her. I’d come across these delightful costumes on the Internet, but had never seen one in the flesh. As she put it on, it aroused quite a bit of discussion.
Jill was rather shy about it, “I know you’re all going to think I’m on the pull or something, but I just want to get a good tan this holiday, with the minimum of white bits…”
It really was about as brief as you could get without going nude – the bra top consisted of two tiny flaps of almost transparent yellow fabric, Jill’s dark aureoles showing through, her big nipples shaping the material delightfully prominently. The bottom, in the same material, had a miniscule strip at the back, revealing her lovely buttocks in just about all their full glory. Most surprisingly, the front just about covered her pussy lips, leaving a good deal of pubic hair showing, both at the top of her pudenda, and between her legs. She hadn’t been nearly as fastidious about hair removal as her sister, in fact I don’t think she’d bothered at all!
To my surprise Helen was really positive about Jill’s immodesty, “ Don’t be silly Jill, you know we don’t mind that kind of thing… it would be nice to go naked here, but you’re about as close as you can get… legally. Anyway, glad to see you haven’t been wasting money on the old waxing sessions…”
“Oh really show?” asked Jill, more to me, as if she hadn’t realised.
“Oh hardly at all”, I joked, “no you look absolutely great, “I’d have brought my tanga with me if I’d known…”
Then came the real surprise of the day. Helen reached into her beach bag and with a flourish pulled out the aforementioned item, which I’d been keeping at the back of a drawer, never realising she knew it was there,
“There you are then, I thought you might want this with you!”
“Oh lets have a look at it,” exclaimed Jill, and took the tiny thing from Helen. “Blimey, it’s as bad as mine Paul, shouldn’t think it keeps you all in ?”
“Well just about it does, I’ll put it on if no-one minds..”
“Go on, put it on Paul, you know you’re dying to…” urged Helen, then with a little shy smile she added, “anyway I’ve got my own little revealing number too as it happens”.
As I stood up and slipped off my sober swim shorts and pulled on the tanga, stuffing my balls and slightly swollen penis into their tiny pouch of fabric, Helen pulled what was little more than a strip of fabric from the bag. Off came her ample costume, and in its place she donned a v-shaped red sash. The two bands just covered her nipples, leaving most of her big breasts bare. The V met at the bottom to cover her vagina lips, leaving her pubes showing nicely at the sides. Wow!
We lay there in the sun, the occasional passers by taking some interest in our bold choice of swimwear, for an hour or two. The main topic of conversation eventually drifted away from our mutual surprise at our costume choices, and all three of us were feeling a lot more comfortable about the situation. My erection, which had threatened at first to pop out of the tanga, subsided, and at length we all took a brief invigorating, if chilly dip. Afterwards both women’s nipples were even more prominent with cold, though my tanga was naturally not bulging quite as much. I needed to warm up, so decided to go for a run. There was a good stretch of sandy beach, the perfect place for a warming jog, but despite my encouragement, neither Helen nor her sister felt like joining me. I left the two beautiful, barely covered, middle-aged women lying in the sun and ran off down the beach. Apart from one older couple I passed no one, the beach being just about deserted. I turned back when I got to the end of the sand, perhaps a mile and a half down the beach. Even the couple had disappeared as I ran back. But as I came around the headland I saw Jill in the distance at the foot of the cliffs. As I drew nearer I saw she was checking out the loose sandy rocks. Helen was nowhere to be seen.
Jill greeted me as I ran across to her, “Hi, nice run then?”
I told her it was great.
“Didn’t scare anyone with that thing then?” she indicated my tanga. Actually it was perfect running wear, just enough to keep my genitals from bouncing around too much, while leaving the rest of me, buttocks included, bare. As of course did Jill’s bikini bottom. She showed me the rather fine fossil shell she’d found, an excuse, as ever, to stand very close to my gorgeous sister in law. I joined her as she picked away at the crumbling rocks.
“Helen’s gone back to sort the kids out at the hostel”, she explained. She pointed a couple of metres up the cliff, “Those flat rocks up there look like they might be interesting, don’t you reckon Paul?”
I agreed, “Yes, you often find shell fossils, sometimes ammonites in that kind of shale.” I watched as she attempted to climb towards the shale. It was a bit of a scramble, but gave me a great view, standing just behind her, the tiny Wicked Weasel bikini bottom hardly showing in her crack. I could see right between her hairy minge, the puffy lips of her vagina discernable through her gorgeous pubes.
She was having trouble. “Do you need a hand Jill?” I offered. She turned to look down at me from the rocks and saw where I was looking.
“Yes please Paul, stop gawking at my arse and give me a push. She could have used many words, but “push” it was, so stepping up towards her I obliged. I braced myself, one leg on an outcrop, the other stretched out, my knee touching her calf. In this position, my legs wide apart, my tanga covered bulge hung down prominently, which Jill certainly noticed, with a rather admiring glance. “Quite the athletic figure in that thing aren’t you!” I laughed and put my palm against her bottom to give a push up towards the shale. My sister in law’s buttocks felt strong but decidedly feminine as she strained her muscles to clamber up the cliff. She reached her goal and began picking away at the shale. The incline was too steep for her to maintain her position unaided. She went up a little further, helped by my hand at her arse, and assumed a position with her left leg touching mine, her calf pressing against my raised thigh, her right leg stretched forward to balance herself. I adjusted the position of my hand to support her, with my fingers against her crutch. I could feel her pubic hair, and whether through exertion or the rising sexual frisson, there was a definite moistness between her legs. We held this position for some time as she examined the rocks. Neither of us spoke for a good while. Her movements as she tried to loosen a large lump of rock stretched her muscles taught against my fingers, and each time she reached forward I pushed more firmly against her groin. I glanced down at myself. My penis was straining against the tanga’s thin fabric, the tip of my glans just poking out at the top. I looked back up to Jill and caught her glancing at me there too. She carried on with her rock worrying.
I was getting a little tired of my position and shifted slightly, lifting my leg to press more firmly against Jill’s leg, a little further up.
At that point she almost whispered, “I know I shouldn’t say this, but that does feel very nice you know Paul…”
“Feels pretty good to me too Jill”, I admitted, and risked moving my fingers gently, but quite obviously, against her vagina lips. To my delight she did not move away, but instead pushed her crotch back down against my hand, at first almost indiscernibly, but gradually more rhythmically and obviously.
Suddenly the rock she was pulling at gave way, and she fell back against me. Together we half tumbled, half ran the few steps back down to the shingle. I lost my footing at the bottom, and whether deliberately or not, I ended up spread-eagled on my back with Jill on top of me, also facing the sky.
There was a moment, maybe a second or two, when we could have changed the course of what was to follow. We covered those moments with laughter, through gasps of surprise and effort. As she laughed I felt my sister in law shift her position, her thighs touching mine as she put her feet to the ground. Still laughing myself I reached out and put my hands to her breasts.
This was it. Definitely. Her nipples were absolutely huge. Hard cherries under my exploring fingers. She put her hands to my thighs, and began stroking them, none too gently it must be said. Suddenly she was like a bitch on heat. She wiggled her beautiful womanly backside against my unyielding stiffness, and I could feel the heat of her moist anus against my penis, now hardly covered at all by the tanga. I reached behind her back to find the clasp of her bikini top and she lifted herself to help me. Freed of their perfunctory covering, her breasts were even more alluring, smaller than her sister’s but more muscular, firmer. She opened her legs wider as my fingers went down to explore her sex. Her labia were loose and stretchy, as I pulled at them delicately and her clitoris was a obvious, tight little bud at their apex. Again she helped me as I pulled her Wicked Weasel bottom down her legs, and she in turn pealed the little scrap of fabric away from my huge erection, and pulled the tanga off. There was no time to waste with oral sex, but we kissed like first time teenagers, breasts to chest, thigh-to-thigh, genitals to genitals. We had to do it, my penis needed to be inside her, and her vagina needed it to be there. With just the slightest help from Jill’s fingers it was done, I was inside the welcoming body of the sister in law I had desired for so long. Her orgasm came so soon, a gasping grunting animal display of love and sexual frenzy. Mine moments after, long urgent driving pulses of semen up inside this wonderful woman’s cunt.
The fossils turned out to be rather special too.
