Well, my cousin, bless her, is kinda innocent. We're very close, she's more of a sister, and we spend lots of time together. We are both 15, and the other day, she was round my house, both of our parents were out, and we were watching tv. I can't remember how the topic came up (pun not intended) but we started talking about masturbation. She said she did it, and that she'd never seen a boy doing it before.
Well, she's extremly hot - tall, slender and blonde - so I thought I'd answer honestly, and it might lead somewhere (hee hee).
I said yes, quite often, and that I'd never seen a girl doing it. She took me by the hand, and led me upstairs to my bedroom. By now, my imagination had started to run wild, and I had a huge hard-on. She sat me down on my bed, and undressed in front of me. My jaw dropped.
Anyway, she started rubbing herself, and I quickly undressed, and took out my 7-inch cock. She reached up and grabbed my dick and stroked away while rubbing herself.
She started moaning, and I could hold myself no longer, and splattered all over her heaving breasts and face.
This is one of the best experiences of my life, and I hope it happens again.
Gotta go and jerk off. Re-living this has made me so horny.
