My Sister's 17-Year-Old Friend

One of my favorite masturbation experiences happened when I was 18. I had been wanking for quite some time and had always wanted to see a girl fuck herself. I had the house to myself for the weekend as my parents were away on holiday. I was looking forward to being able to jerk off whenever I wanted, but to my dismay my 16-year-old sister and her 17-year-old friend were staying the night. They had a few drinks so I left them to it.

I went downstairs in the early hours to get a drink when I saw a light in the living room. I walked closer and heard some noise. As I peeped through, there was porn on the TV and my sister's friend Claire was lying on the couch with her legs spread wide. Her hand was rubbing her pussy. My cock sprung to life as I watched her hand rub faster. She paused as I began to stroke my hard dick. She then pulled out a vibrator and began to insert it into her pussy.

I groaned a bit too loud. She sat up and told me to come in so I did. She said she would continue if I wanked in front of her, so I began to pump my cock faster as she inserted the buzzing cock in her cunt. She bucked her hips as she reached her orgasm, moaning loudly. The aroma of her pussy was in the air and I could hear her pussy squelch. My balls tightened as I felt myself ready to cum. Claire opened her mouth and beckoned me to cum on her face. I pumped faster as she licked my balls. I shot at least four shots of spunk on her face. We still talk about that night and have moved on to further stages.
