Swimming with MIL 3

I froze, I literally had no idea what she was going to do. Her hand was on my thigh, quite high up and not touching my stiffy at all but the back of her arm was pressed right against it.. There was no way she couldn't feel it and as the bouncing continued the arm rubbing, intentional or not, did its job. I came again, fucking fountains of cum in my shorts.

I let my right hand drop over her her tit as I moved back from her, just brushing but lucky enough to feel the hard erect nipple under her swimsuit. Erect because of what happened or just because it was cold? I don't know, i really don't but I'm sure she knew what was happening..

The rest of the swim was uneventful except one little peek of some pubes ( and maybe lip ) as she sat on the side of the pool. Sitting on the edge she reached back to get a drink and her legs opened just enough to give me a wonderful eye full of crotch. Brown pubes each side of her swimsuit and I'm pretty sure a tiny bit of lip was showing. This might have been my imagination after the days events but its one that stays in the wank bank..
