[George VI]

ThomasMoore, this story barely meets your "go beyond just catching a peek" requirements, but it's the best I have. I had a lot of voyeurism adventures with my SILs in my youth, not so much lately, but I never had sex with any of them, or even got in a good grope or wet kiss. Only one of them, my wife's sister Kay, ever did much flirting with me. Perhaps the best was a week we spent at a lakeside cabin with our spouses and other in-laws. This story doesn't end bad, but it doesn't end wonderfully either.

We were all in our late twenties, had been married a few years, and none of us had kids yet. Kay was a degreed professional, an attractive brunette with a slender body and little titties. She always wore glasses over her cute little button nose, looking a little bookwormish. Kay and her husband lived in a different state, so I didn't see her all that often. Kay was sort of touchy-feely, one of those persons that puts her hand on your arm as she's talking and stuff like that, and over the previous year or so she'd escalated that to rubbing her thigh against me when we sat next to each other, then rubbing her shoulder against mine, and then she got into boob rubbing, which isn't an easy thing for a small-breasted woman to do - she had to arch her back and really work at it. But all of this was done just behind or barely out of sight of our spouses, as we were never alone - there were always spouses or other relatives within eyeshot and/or earshot.

So at this cabin, my wife and I shared an attic/loft with Kay and her husband. It was all one room with a staircase in the middle of the room, and a bookcase acting as sort of a partition between the two sides of the room. My wife and I slept on a bed at one end, and Kay and her husband slept in a bed on the opposite end. The bookcase didn't really hide much.

I'd seen Kay's little titties a number of times in downblouses in her bra, and in nightwear. But the first time I saw her completely topless was the first night we stayed in the loft. I was in bed, my wife was getting ready for bed nearby with the lights off on our side, Kay's husband was in their bed, and Kay sat on the edge of their bed. She peeled off her top, then unhooked her bra and dropped it, and I saw her topless. Suddenly her tiny tits didn't look so unimpressive - they were gravity-defying in the way that they stuck out and high on her chest, with her little light brown areolas and nipples sticking straight out.

The next day at the beach, Kay wore a one piece bathing suit, that was too loose over her little tits, so that I was often seeing her nipples when she leaned at all forward. I saw them when her nipples were soft and warm in the sun; and then I saw her coming back out of the lake when her eraser-sized nipples were wet and erect and her areolas were very puckered and shriveled.

In and around the cabin, Kay often sat next to me on swings and love seats, rubbing her bare legs against my bare legs, and pressing her shoulders and tits into me. So there was a lot of physical flirting, but nothing spoken - we were never ever alone.

One morning I was sitting across from Kay as she sat in her nightgown on a couch. Her legs parted a fair amount, and I instinctively gazed down looking for a panty upskirt. But I realized that she wasn't wearing panties, and I was looking right up her nightie at her bare pussy, covered with brown pubic hair. Later on, I stood at the bottom of the narrow stairs to the attic while Kay climbed them, and got a good view of her bare beaver up her nightie. Kay looked down and gave me a little smile as I looked up at her, like she knew what she was showing me.

The flirting went on all week and she was driving me wild, but being around family all of the time, I couldn't say anything to her and was reluctant to get too grabby in case I misread her and she might react wrong - the dilemma of taboo flirting. I've been wrong about flirting women's intentions before, and didn't want to make a monumental blunder.

The last full day we were there, we frolicked on the beach as usual, and then in mid-afternoon came inside and cooled off in our nearly-dry bathing suits. It was me, Kay, our spouses, and a few other in-laws in the living room and kitchen.

Kay then announced that she was going to go up and get changed into clothes. Realizing that this might be my opportunity to be alone with Kay while she was undressing, I also stood up and said that I was going to go get out of my bathing suit. Nobody else in the room seemed to put two and two together. But when Kay started to approach the stairs, she walked with what seemed like an excited gate, and smiled back at me like she knew that we would soon be alone and undressing in the same room.

Upstairs, I went to my side of the attic, and Kay went to her side. In reality we were in the same room, perhaps thirty or so feet apart - close enough that we could talk in normal tones to each other. Our spouses and other relatives were just down the stairs below us.

I stood right out in the open beyond the little bookcase partition. I started to strip, and was soon naked, while watching Kay. But after laying out her clothes, Kay said, "You can't come over yet, George." Like she actually expected me to not look at her. She turned her back to me as she peeled her damp bathing suit down her torso, and then her butt, revealing to me for the first time her bare white late-twenties married ass. She bent at the waist as she pulled the suit down her legs, and I could see her hair-covered pussy between her legs.

Watching Kay put on her white panties and bra with her back still to me, I had too-quickly gotten dressed. So I said to Kay, "Oh, I forgot to put lotion on my sunburn." I quickly stripped completely naked again. At this point I don't know if she'd looked at me at all. The stairs were between me and Kay, so she would have to walk nearly right up to me to go downstairs. My cock was hard and nearly at full length, but not sticking straight out - it was hanging down. I didn't want to stand straight facing Kay - I was still nervous about our spouses downstairs. So I faced sideways, with my clothes laid out on the bed in front of me, and didn't look directly at her as I heard her walk over to the stairs. But there was almost no way that she couldn't have seen me there completely naked and standing sideways.

Of course in retrospect I wish I had been more forward, said something, touched her more. But it was a taboo situation, I was careful and slow to react and a bit wimpy, and I'd only been married a few years and not looking to wreck it. And that was the end of a week of naked flirting with my sister-in-law.
