Greatest Sleepover Ever

Freshman year in high school was the year that I had my first sexual encounter with a girl. We had become really good friends over the summer and when school started we had all the same classes and we sat next to each other in each. We were getting together for a sleepover one weekend to prepare for mid-terms. I went to her house and we ordered pizza and went up to her room to eat and study. The night started off well but when we moved onto math I was having a lot of trouble remembering what to do. She presented the idea that every time I answer a question right, she takes a piece of clothing off. I reluctantly agreed and she started to ask me more questions and wasn't doing well until I finally got one right and she took off her shirt to reveal her bra. I got two more questions right and she was down to her panties and about to take her bra off, I was so horny that it was nearly impossible to pay attention or hide my massive erection. When she took her bra off and revealed her breasts I moved my hand to my pants where my cock was and started to rub. I got the next few questions wrong because I was so excited that I couldn't think and when I got the next one right she smiled and took off her panties with her legs closed. My cock was so hard it hurt and there was a wet spot in my pants from my pre-cum, and when I got the next question right she spread her legs to show her beautiful, tight, pink pussy. She said that she wanted to study too so she made me ask her questions and for every one that she got right I would take a piece of clothing off. She was a lot smarter than me so it didn't take long before I was down to my boxers and my cock was making a big tent in my boxers. My boxers were also soaked with pre-cum and when I took them off my cock bounced up and flung pre-cum onto her stomach and she she wiped the glob up and sucked her finger clean. We just looked at each other and then pushed our school stuff off the bed and she laid back and spread her legs and said, "Go ahead, do what you want, play with her." I got between her legs and ran my finger around the edge of her pussy. It was warm and very wet and I put my face down and put my nose in it and sniffed. It smelt nice and made me even hornier. I knelt over her and started to kiss and feel her breasts and French kissed her. I went back down and started to rub her pussy with my hand and stuck my finger in and started to finger fuck her. I then put another finger in, she started to moan and move her hips in rhythm with my fingers. I took my other hand and began to play with her clit and pinch and flick it and when I would flick it she would twitch in pleasure and moan louder. I wanted to put my cock in her tight little pussy and fuck her so bad but I knew all about pregnancy and to use a condom every time so I didn't. She said she was going to orgasm and to stop and that it was my turn. We switched places and I was laying my back and she put her hand around my cock and started to stroke me. She then realized how large my scrotum really was and held it and squeezed my balls. My scrotum is really large and hangs down about 6 to 7 inches and my doctor says it's nothing to worry about. So as she stroked my pre-cum soaked cock she put my whole scrotum in her mouth and my scrotum was to big and was making it hard for her to breathe so she just sucked on my balls. I was about to cum so I told her to stop and told her to get on her hands and knees and she did. I got behind her and slipped my scrotum between her ass cheeks and reached around and rubbed her clit. She said that she really liked the feeling of my balls in her ass and that it makes anything to do to her pussy feel even better. I pulled my balls out and she rolled over and they fell on her pussy and she pulled me closer so she could put them in her and after a few minutes of me tea bagging her pussy and motioned for me to put them in her mouth. So I got up and put them over her face and slowly dipped them into her mouth while slowly and lightly playing with my cock. She took all of my 7 inch scrotum into her mouth so they were going down the back of her throat like she was deep throating a cock. I told her that I had to cum so she put my cock in between her boobs and I and started to tit fuck her while she was still deep throating my balls. I shot my load all over her stomach and four strings of cum covered her inner thighs and the edge of her pussy. I wiped up all my cum with my scrotum and she sucked them till them were completely dry of my cum. We were already in the 69 position so I put my head between her legs and licked the inside of her thigh and edge of her pussy and sent shivers of pleasure through her whole body. In shoved three fingers into her pussy and thrusted them in and out hard and tapped and flicked her clit with my other hand until she started to moan and scream louder and louder until I felt her climax she squirted all over my hands and face. I continued to thrust my fingers and she came three more times before finally falling limp on her bed and breathing heavily. I then continued to lick all of her cum off over wherever it was and sucked on her her tits and bit them lightly. When she could talk again she said that those where the best orgasms she has ever had and the most she has had in a row. We laid in bed in each others arms completely naked for a while kissing and I was playing with me tits and cupping her still dripping pussy for a few hours until we were horny and ready to go again. But right now I could go for some release so I'll write it up another time.
