My brother's girlfriend.

Back when I was 15 i had the greatest experience of my life with my brother's girlfriend. My brother had taken responsibility for me after my parents died he was 18 and had the hottest girlfriend I had ever seen. She was 5'7", had black medium length hair, long smooth legs, large breasts (either a large c or small d-cup), and she had the nicest ass! 
One day while my brother was at work I decided to sneak a camera into the bathroom and hide it under a stack of towels, so when Melissa woke up and took a shower I'd have something to jack off to later.
After she had taken her shower I went and took one (to retrieve the video camera). After I had stashed the video in my room I went dwnstairs to eat lunch. I couldn't help but stare at Melissa as she cooked. She was wearing tight leather pants with no panty lines showing, and a tight shirt that looked as if her breasts were going to tear straight through it. I felt my cock begin to rise so I quickly sat down to hide it under the table. When melissa brought the food over to the table she bent down to place it in front of me and I got a perfect view of her cleavage. My cock began to hurt I needed to relieve myself. I quickly ate then explained that I was tired and was going take a nap. "OK, I'll just keep myself company" ,she said smiling at me.
I ran upstairs into my room and popped in the video. I hadn't remebered to lock my door. I was watching the video and jerking off when I heard my door open. Melissa was standing there with her eyes fixed on me. She quickly recovered and gasped, "Oh my god! You little pervert!" And she shut the door. I ran out of my room before I even put my pants on, and could only think of one thing, "Melissa you're not going to tell my brother are you?" I begged. She turned around and gasped, "PUT SOME PANTS ON OR SOMEHING!" I realized how awkward she must have felt so I ran to my room and put some pants on.
When I came back downstairs I had my mind set on convincing her not to tell my brother. She sat me down then sat down next to me and said, "Listen kid I won't tell your brother a thing. I should have knocked before entering. If anything I should be getting punished. How about you just give me the video and we forget about this entire mess. Deal?" 
"OK, I'll go get it." ,I said realizing how lucky I was that she wasn't going to tell my brother.
I went upstairs and still having to relieve myself began jerking off to the video again. My door opened again and she walked in. "OH NO!" I thought. Stupid me had left the door unlocked again. I pretended to act like it was her fault. "Why don't you knock?" I yelled. "I'll teach you 
you little bitch!" I grabbed her by the hair and pulled her over my lap. I began spanking her violently and listened to her yelp in pain. This only aroused me more and my hard cock began pressing into her stomach. I pulled down her pants a little exposing her ass and began spanking it. She was still yelping, but I could tell she was starting to get aroused. I pulled her up by the hair and then pushed her onto my bed. I leapt on her and ripped her shirt off exposing her large perky breasts and I began to rub her left breast while sucking on her right nipple. She began to moan softly, and I realized she would not stop me now. Her nipples quickly became erect as I sucked and massaged her breasts.
After playing with her breasts for a while I pulled her pants the rest of the way off exposing her beautiful pink shaved pussy. I slowly moved my kisses down her stomach until I reached her pussy then I began 
licking her pussy lapping up all of her juices. She began to moan loudly so I stopped licking and started to guide my dick towards her pussy. "No, in the ass", she said. So i grabbed her by the hair and stood her up. I put some lotion around her asshole first to lubricate then I bent her over and becoming very excited I rammed all 6 1/2 inches of my cock into her ass. She screamed in pain but as I began pumping she began to moan in pleasure I ran one of my hands between her thighs and began fingering her wet pussy. Her body began to shake and she orgasmed at the same time that I shot my load deep inside of her ass.
Me and her never had sex again, but she never did take the videotape away from me either...
