Bikini Wanking

When i was around 14 my friend had a sister Jessica that was around 17 and knew she was hot. She would tease me all the time with touching and some dirty talk. One day I went over to my friends house to see if he was home and she answered the door in her thing bikini. He' not home but you can hang if you want. My mouth must have been on the ground when she answered the door she looked super amazingly hot with her tits out and her as cheeks showing in that thong. Again she knew I was blatantly staring. when she said I could hang injust said oh yeah ok cool and we went outside. She was laying on this sun lounger as we talked for a while. Then she tossed her towel in front of me got up and bent over right in front of my face with a great view over her ass and pussy, she then sat on my lap and i obviously got hard pretty quick, she felt it on her ass of course. She started grinding me and bouncing on me. I mumbled "holy shit" she turned around and keeled down in front of me "want to take care of that" I nodded my head yes,go ahead then, here I said? yeah do it, she i whipped my shorts down, I asked what she wanted me to do? she told me to start jerk off so I did she tell told me to cum on her so when I was ready i God damn exploded on her tits and it felt sooo good.
