The summer before my senior year of high school, I spent a night with my sister's friend Mary. A naturally skinny 15 year old, Mary was small all over, but big into exploring her sexuality.
One night, my sister was out with some friends, and out of boredom, I had started to text Mary. Next thing I know, I had invited her over. With nothing to do at my house and an obvious tension lingering, we decided to take a walk.
It was a hot late August evening and we ended up on a small beach just down the road from me. For a while, we simply sat and flirted, we were in a bit of an awkward stage, but before long, I leaned in and kissed her. Before I knew it, we were undressing each other in the sand.
I quickly stripped Mary down to her tight black panties, sucking on her nipples and caressing her all over. Swiftly, she guided my finger into her tight shaved pussy. She moaned as I begin to rub her clit, and before long she pulled off her soaked panties and my damp boxers.
Buck naked, I fingered her while she began rubbing my cock onto her rock hard abs. I could feel the muscles in her pussy tighten as she came. My finger's soaked in her cum, I took Mary's hand and helped her finish jerking me off onto her small, pink nipples, both of us holding the other tightly, wrapped in each other's body fluids.
Needless to say, it was a hell of a night.
