When I was thirteen I had a cousin that was one year older than me. We had been playing around with each other for awhile when she got a boyfriend. He was sixteen and had a car. When he took her off in the car he would take her to a parking spot and fuck her. He wanted her to suck his dick but she had never done that before so she sorta dared me to let her practice on me
.
We had already fooled around a lot and I had fucked her a couple times and she had jerked me off many times but she had never had my cock in her mouth. I must say, she was a natural at sucking a dick. The first time she sucked me I didn't even think to warn her that I was about to cum and the first spurt gagged her a little but she swallowed and kept on sucking.
Not long after that she dared me to let her younger sister suck me off. That was really a lot of fun, the younger sister sucking me off while the older sister watched.
I'm not sure if that was a truth or dare or not but it sure was a lot of fun...lol.
