This happened over 15 years ago, at a frat party.
I'd met Mark on the dance floor. I didn't think he was all that cute, but there was something a little sleazy about him that made him sexy. After just two songs, he asked me back to his place. Dancing with him had made me wet already, and when he began kissing and sucking my neck, I started to consider it. When he said he wanted to shoot his cum onto my chest, I couldn't resist.
It was about a 15-minute walk to his apartment, but we kept stopping along the way to make out. Soon I could feel his erection hot and rock-hard against my thigh. I grabbed it with my hand, and he moaned, pulling away.
When we got to his place, we wasted no time getting naked in the living room. He said his roommate probably wouldn't be home for a while. Then he ordered me to lay on the floor and spread my legs. Although the carpet was hard and scratchy, the idea of being told what to do made me even hotter, especially since he didn't seem to care if his roommate arrived and saw me exposed like this.
He kneeled over me and generously lubed up his beautiful, uncircumcised cock, giving me a great view of the underside when he slowly started stroking. I certainly didn't need any lube as I ran my fingers over my puffy, wet labia, so sensitive to the touch. I could feel my juices leaking out of my pussy and running down to my ass. It wasn't long before I couldn't resist touching my clit, which felt huge to me in my excitement. I had to be careful because I wasn't far from cumming, and Mark was still working his cock slowly while staring at my breasts. They swayed gently as I began rubbing harder.
Mark's movement's were starting to get a little jerky, and I could tell he was drawing close to orgasm. He began working his cock faster until he climaxed hard, his cum spurting over my chest in waves. The sight of his prick emptying onto me, as well as the almost pained expression of release on his face, sent me over the edge to a loud orgasm. He immediately reached out to cover my mouth, silencing me roughly, which excited me enough to keep my climax going for what seemed forever.
Then I had laid there, spent, my fingers lingering in the folds of my sopping wet pussy, until he pushed them away with his own. Although my clit was still so sensitive that it hurt, I let him continue his gentle stroking, while I rubbed his cum into my chest. After a bit, my excitement had chased the sensitivity away, and I pressed my hips toward his fingers, wanting him to rub harder and faster. He laughed and stilled my hips with his hands, telling me I had to remain motionless and silent or he would stop. I nodded jerkily, and he moved his hand back to my pussy.
Mark reached inside my cunt with two exploratory fingers, massaging the walls until he found my g-spot. He began rubbing it slow and hard, while his thumb kept up the same rhythm on my clit. My orgasm came quickly and shatteringly, and it took all my self-control not to scream with pleasure.
I got up and dressed to leave, and he didn't try to stop me. I never met up with him again, but thinking about the sight of him pumping his cock over me has sent me to some of the best orgasms of my life!
