The first time I ever masturbated with someone else was the time with my cousin when I was fifteen. My cousin was also fifteen at the time.
It all started when my cousin caught me playing with myself. It was very embarrassing. But she said she liked seeing me masturbate and that see could even help me. I said I wanted her to help me. So she wrapped her hand around my penis and started to stroke gently.
Feeling her hands around my penis felt many times better than my own. I got more excited than ever because I knew I was being masturbated by my cousin. The feeling was so intense as I was about to orgasm. It was the best feeling ever in my life. Then I ejaculated so strongly my cum flew onto my belly and chest. It also flew into the air and it covered my cousin's hand.
My cousin said she enjoyed seeing me cum and she would help me masturbate whenever I felt like it.
