One day I was home alone horny as any other day, when my cousin Steph came by. Steph is 15 and lives next door to me. She's about 5'3, 36C and has a nice, nice, nice ass.
I was lying on my bed wearing a tank top and boxers.
Steph is in the cheerleading team and is very flexible. She asked me if I wanted to see her walk with her two hands, and I said yeah. She had a skirt on and I was able to see her panties and some of her pubic hair. This made my cock very hard and I started to stroke it under the sheets.
She noticed my hand moving and asked me what I was doing, and I said 'Oh, nothing I was just scratching.' All of a sudden she pulls the sheets and sees my raging hard-on through my boxers.
She said she knew I was masturbating and that she does it too about twice a day. She said she's never seen a cock before and would like me to masturbate in front of her. I said only if you do it also. She thought about it and said 'Fine'. I dropped down my boxers and she said 'Wow, it's veiny and big.' My dick is about 7 inches and thick.
I was stroking it when she asked me if she could do it for me. After about 3 mins of this I came all over my chest and some of it fell on her thighs.
She hadn't yet taken off her clothes so I said your turn and she pulled down her panties and took off her shirt and left her bra on.
I could tell she was very wet because I was able to hear the wet noises when she fingered her pussy. She asked me to do it for her and I started massaging her clit and managed to take out her tits. Then I stuck my fingers inside her and boy was she wet, it felt like someone left a faucet running. She was moaning, and this got my dick hard again.
After about 4 minutes she started to shake and said she was cumming. I started to jerk my dick faster than ever and came in about a minute all over her chest and face. We cleaned up and agreed not to tell anyone and to try it again in the future. I CAN'T WAIT.
