I lifted the skirt and petticoats to look at my panties and admired the lace as it was held up for view by my massive erection.I rearranged my skirt a...d sipped my drink and listed to the music when suddenly my heart stopped beating. Coming from the hallway was the sound of more than one person singing happy birthday. Surely Sally Anne would not have arranged a surprise party when I was sitting here dressed as I was. I thought about running but there was no where to go. I had to go into the hall. Barely a teenager, I secretly now only fantasized about cock. Fighting my urges, afraid of what family and friends might think, it was a few more years until I had my first experience with another male. I masturbated every night, sometimes two or three times to the thought of sucking cock, any cock really. It went beyond curiousity. I had fantasises about kissing men pleasuring them and even being taken by them. Having them use my ass and mouth for their sexual needs. I was sure these were not. I've always thought of fucking Allison, doing dirty things to her. When I jack off I think of her sucking my cock and licking my ass to get me off. I think she knew that I wanted her ass. Sometimes when she turned to look at me I would keep my eyes fixed on her ass. One night Allison her sister and myself were talking about fetishes and what our turn ons were . Mel her sister started and told us that she liked to be fucked hard in her pussy. Allison explained that she liked it when a guy licks. I put my hard dick in the crack of your ass and slide up and down like I'm fucking a girls titties except this is sliding across your satin panties. I slap your ass cheek once and your jump and let out a squeal. I rub up and down some more then slap your other cheek. I'm hard as a rock now. I grab your panties and rip them open on one side and they fall down to your knee on the other side.I thought I was going to slam into your gurl pussy, but now that I see your naked ass I have other ideas..
