I was chatting with my roommate the other day and the conversation turned to sex. You see, she's a very attractive blonde who gets asked out all the time and has sex probably 1-2 times a week. I look more like a librarian and hardly ever get asked out. Anyway, my roommate was bragging and teasing me and finally I told her I could have a date over to our apartment that evening who would fuck my, and only my, brains out. She laughed at me, knowing I hadn't even been out on a date in months, and longer still since I had been laid. I felt like I had to live up to this one, and I bet her $500 that a man would fuck me that evening in our apartment. She took the bet and I laughed in her face, walked over to the computer and logged onto an Internet site called Adult Friend Finder. I put up an ad stating that I wanted a man to fuck me that evening in order for me to win a bet. I stated in the ad that he must only touch me, and not show any interest in my more attractive roommate. I got a response about 2 hours later and he showed up at our apartment that evening. I smiled and let him in, whispering in his ear the agreement we had for him to come over. He said he would comply, and whispered back in my ear that he though I was more attractive anyway. I got hot for him immediately and I took him by the hand to my bedroom. We undressed quickly and before I knew it I was sucking his cock. Then my roommate came into my bedroom and sat down on the bed. She smiled and said she would have to witness this before she would pay up. She had changed into a hot tight black lace body suit that any man would kill to see her in. She flaunted herself all over my date, but he didn't even notice her and gave me all the attention. Then she took off her suit and tried her best to get my man, but he bend me over and fucked me hard, not paying any head to my blonde slutty roommate. He fucked me good and hard and I got soo excited by the fact that he was fucking only me that I came at least 4 times. I got soo hot that my roommate started to play with herself and although my man would not give into her temptations, I couldn't resist and I ate her out while I continued to get fucked. Finally he finished by blowing a huge load all over me and then kissed me goodbye, not even saying one word to my roommate. She was shocked, and readily gave me the $500 she now owed me. She begged me to tell her where I found him, and finally I did. I'm sorry I did though, cause she now fucks a different man almost every night through the Adult Friend Finder system and I hardly get a moment alone anymore without listening to her moan away through my bedroom wall.
