The first time I walked in on my roommate downloading porn with one hand down his pants, I was embarrassed. But after the fourth or fifth time, I just started to be bugged by it. Instead of hitting on me, he was just looking at women on the internet. I'm good looking. I don't know why he does that.
Finally, I decided to do something about it.
For the next week I was always really quiet when I came home. I didn't want him to hear me. Finally one day I found him looking at porn. I snuck in the room quietly and kneeled behind me. By the time he heard me and started to turn around, I snuck one hand around his waist and put it on his right hand, the one he was masturbating with.
I didn't say a word. He was too shocked to say anything. I started guiding his hand up and down his shaft. It was actually pretty big... I was surprised.
I grabbed his right hand with my other hand and pulled it away so I could stroke his cock. He moaned and closed his eyes. He rolled his chair back, and I got the hint and crawled over in front of him. Keeping my right hand massaging his cock, I unzipped his pants with my left. With one motion, I pulled his cock out of his fly and started playing with it with both hands. He moaned again, and leaned back in his chair. I stopped playing with him for a second to whip off my shirt. As I leaned down to kiss the tip of his cock, my breasts brushed against his legs. He put one hand on the back of my head and pushed me towards his cock a little, so I put the tip in my mouth. With my right hand I kept playing with the shaft.
He reached down and started fondling my breasts while I sucked the tip of his cock. He moaned, and I went down further until I had half of it in my mouth. He reached behind me and unclasped my bra. It slipped off easily, and my bare breasts rubbed up against the inside of his legs. I went up and down on his cock while he played with my bare tits some more. Finally, I stood up, and reached under my skirt. I lifted it up, and he pulled down my thong. I straddled him. "Don't worry.", I said, "I'm on the pill." And with that, I grabbed his cock and led it to my hole. This hole thing had been turning me on so much that I was already wet enough to let him inside. All 8 inches of him filled me up and hit my g-spot right away.
"Oh jesus!" I screamed and started grinding on him. He grabbed my ass and started bouncing me up and down on his cock. While he was doing this, I pulled his shirt up as far as I could. He let go of my ass long enough for me to pull it off of him, then he grabbed me again and kept going, just as fast and hard as he had been before.
