While my sister and I were laying down in bed dreading, Like always school the next morning. We tossed and turned hesitant to fall asleep. One of us w...uld accidentally rub up against the other and the other would shove away, acting to be getting upset. Finally later in the night we settled down with less tossing and turning. Our legs closely to each other. My heart was pounding pretty hard as I wondered if she we shove away again if I made the move to touch her feet with mine so I decided to be. James lowered the cab lights and pulled curtains up in the windows, then sat in the front seat and pulled out a book. Potbelly grabbed my head and pushed my face roughly down into his open fly. I could smell his sweat as he pulled his cock out and started slapping it on my face. Behind me, I felt Skinny pull my knees up on to the cot and slap my ass cheek. He put both hands on my cheeks and pushed them apart, then moaned. Potbellys cock, now hard, forced its way into my mouth and down my throat. It was an incredibly erotic feeling.One that she knew she wanted to experience again and again. Later as they lay there in each other's arms, she turns to him and says ?Atfirst I was so angry with you for spanking me, but then I realized how muchit turned me on. I now realize that you did it for my own good. I might neverhave learned how erotic anal sex is if you hadn't pushed me. Thank you.? Hedoesn't say a word, just nuzzles her hair and then kisses her on the lips. For the rest of the day,. We both got comfortable and he sucked me for a while, I was fully hard when he took it from his mouth and began stroking me. He asked if I wanted to fuck, and being a horny teen at the time, I didn't reject him.He arched forwards on the bed, raising his ass to the air. Presenting himself as he spread his legs. I sat up and quickly stumbled to get it in. It took a few tries, he was tight and we had no lube, but it got in. ( Without a condom, stupid young mistakes but I got lucky ) My first.
