So my wife’s sister came out to visit and stayed with us, our community had a pool and we all went. My wife was sitting in the side of the pool in one of those wavy looking chairs chilling, her sister had gone over towed the opposite side of the pool, she was wearing this cute two piece and I decide just to see what she would do if I accidentally grazed against her.
I go over and go up behind her but I just let my dick rub up against her butt while she’s leaning on the side of the pool. She didn’t really move or wiggle her butt or anything so I stopped and a I was going away I looked at her and she said “boy you are so full of it” and went back to leaning on the side of the pool. I went back over and said “what?” And she didn’t say anything so I reached in the pool and pulled my dick out and let it rest on her butt and she didn’t move or say anything, I slid her bottoms over and tried to put my dick inside her and she let me get about halfway in and then pulled away and was like “uh uh you are trouble” and she swam away but she never told my wife so I’m guessing she liked it somewhat
