Listening to Nicolette

When I was a senior in college, I lived in a house with three guys and a girl who lived upstairs. At the end of senior year there was a one week gap between the last final exam and graduation. Some people went home but others stayed to spend time with their friends. There was a lot of drinking and partying going on during this week. My two other roommates went home during the middle of this week, so for a few days only myself and Nicolette, the girl who lived upstairs, were living in the house. One night, Nicolette came home from the bar, and she had brought along a guy with her. She had been sleeping with lots of guys because she had recently broken up with her boyfriend and seemed to be horny all the time. I knew what was going to happen next, so I watched TV in the living room and waited for them to go upstairs. Nicolette is very attractive. She has long dirty blonde hair and blue eyes. She works out and has a nice ass. She has rather large boobs but not to the point where it is unattractive. They definitely grab people's attention but dont ruin her figure. What I found the sexiest though was actually her voice. It made her sound so beautiful and innocent even though it is pretty cleat that she gets around.  Around midnight, Nicolette and the boy she brought home went upstairs. They had been drinking but weren't sloppy drunk. She was very touchy-feely and was acting sexier than she usually does. When I heard them close the door to her bedroom, I went halfway up the stairwell and started to listen to what they were doing.  I heard them making out for what seemed to be a long time, then there was a little pause. I heard her laugh and giggle, acting all sexy for her boy toy. Then I started to hear her moan softly but also heard what seemed to be kissing, but then I figured that the boy was eating her out. At this point I started to get really horny. I unbuttoned my pants and pulled my dick out of my boxers. I began to stroke it slowly as I listened to Nicolette moaning in pleasure. I closed my eyes and imaged her naked on the bed, her legs spread apart and her breasts rising and falling as she breathed deeply with each sensastion of pleasure.  I started to stoke fast as I imagine her on her back squirming as she moved closer and closer to orgasm. I imagined getting on top of her and making her moan as I fucked her missionary style. Knowing I was alone in the house I dropped my pants and boxers to my knees and got some tissue to clean up. I freed myself more by taking my pants and boxers all the way off. I began to stroke faster as I envisioned her on her bed as I listened to her moaning on her bed. Occasionally I would hear her laugh and giggle to her guy, which made me even hornier. Suddenly I heard her moan really loundly which indicated that she just had an orgasm. It was so sexy the way she let out this gasp. I knew at this point I was reaching my peak. I pumped my dick faster and faster then shot out a huge load. It was one of the better orgasms I've had in a long time. I missed most of the kleenex and got alot on my shirt and some on the stairwell. I made sure I cleaned up after myself so Nicolette would never know ;)
