This happened years ago and I still think about it sometimes when I touch myself. Friends and I were all going swimming during one summer. One of the times we did it we were playing Marco Polo. One of my friends (let’s call him Dan) started getting really grabby. He was cute so I let him.
Eventually I started feeling his sick rub up against me leg or waist because he kept swimming up beside me while we were all playing. At one point I suddenly felt his hands between my legs and stroking me.
I tried hard not to be obvious so other people wouldn’t notice but it was def turning me on. Next I felt one hand slide my swimsuit to the side and his dick enter me from behind. I almost fell over but he steadied me and we drifted towards one of the side walls. My other friends weren’t paying attention and he started fucking me up against the wall. It was so hot. Whenever a friend would turn around to look where we were they couldn’t tell what we were doing so it turned me on even more. He had to cover my mouth when I came.
