"It's so hot," I said, and it was. "Would you mind if I went in for a swim, Uncle Roy?"

He shook his head with a smile.

"Why don't we both dive in?" I suggested, toying with the fold of my scarf-dress. He grinned and shook his head again.

"I don't have a suit," he apologized.

"Neither do I," I confessed, undoing the knot. The long, slinky scarf dropped to the tiles and I stood there, naked. Uncle Roy looked as if his eyes were going to explode out of his head, and I saw him swallow very hard.

"Swimsuits are so archaic," I added, strutting to the edge of the pool. My ass twitched as I walked, but it always does, and I could feel his eyes fixed upon me all the way.

I stood there for a moment, basking in the warmth of the Ohio sun, and then I dived in.

I showed off for him in the water. I'm a good swimmer and I did a lot of aqua tricks, and I made sure that he got an eyeful of tit and ass and pussy besides. From the pool I could see him in his chair, his eyes intently watching me over the rim of his glass. Score two points for Jenni.

Finally I climbed out of the pool and stood on the tiled edge, drying myself with a towel. I felt good after my swim, no hornier than usual, and the cuddly soft-rough of the towel was so invigorating on my skin that I really got into drying off. If Uncle Roy hadn't been there, I'd probably have lain down on the tiles and finger-fucked myself to a come, just because it felt good, but that would have been carrying things too far. Teasing him was all I had in mind, teasing him because we were alone and because I knew I could do it and because it was such a neat idea.

I looked at him from the corner of my eyes to see how he was taking it, and I nearly fell into the pool. It was working like crazy.

Uncle Roy had taken off his jacket when we came outside, and he was sitting there in his shirt sleeves, his legs crossed. But his pants were fashionably snug-fitting and even crossed legs couldn't disguise the fact he was excited. The front of his trousers was tented with what looked like an incredible hard-on, and I knew that I had caused it.
