Fucking in a pool changing room [MF]

This was over ten years ago between me and my now husband, but still gets me going thinking about it. I’m pretty petite but still fairly curvy despite my size, and vack then had short blonde hair.

It was new years and we were partying at his friend’s house who had a pool. Ben and I had had a few drinks and were taking a swim. His slightly crazy ex girlfriend had showed up but was sitting on the side of the pool blatantly ignoring us chatting to another girl. I’m not entirely sure why but her being there made me slightly more daring, and I kept subtly stroking Ben’s cock over his swim shorts every time he came near me. He would give me a sly smile, but we kept it fairly discreet from the rest of his friends who were swimming with us. After probably twenty minutes of me doing this Ben abruptly said let’s get changed, and we made our way to the changing room on the side of the pool.
