I went to Susan's room (my older sister) to borrow a blouse. As I was standing at the closet, I heard her and here boyfriend talking in the hallway. I didn't want to get caught in her room so I ducked into the closet and left the door just partly ajar. Susan and Tom didn't waist any time before they started making out. As Tom stood at the end of the bed, I watched Susan unzip his pants and begin giving him a blow job. As she went down on him, he had his hands busy playing with her tits. I began getting hot just watching his hugh cock sliding in and out of Susan's mouth. As I reached down and began fingering myself, Tom began undressing Susan. Once she was completely naked, he slipped his shirt and pants off and laid down atop of her on the bed. I watched as he buried his hugh cock between Susan's legs. She was really enjoying his manhood between her legs and I was really getting worked up as I fingers my cunt. When I accidently banged my head on the closet door Susan called out to me. I was really embarrased when I stood there before the two of them. Susan asked Tom if he would like me to suck him off. Why of course he agreed. Before I knew it I was kneeling in front of him and letting his cock slip into my mouth. His balls kept hitting my neck so I reached up and took one in each hand and gently squeezed them. Tom let out a soft moan and tried to force his cock more into my mouth. My sister asked Tom if he wanted to pluck a cherry. A weird expression formed over TOm's face as he looked down at me. The two of them quickly undress me and had me lay on my back on the bed. Next Susan carefully parted my legs and then lowered her face to my twat. I quivered as she raked her tongue over my mound. The felling of her soft breats against my thighs really excited me. As Susan continued tonguing my privates I looked up and saw Tom humping Susan from the rear. Next I heard him call out that he was almost ready to pop me. Susan came up for air and told Tom that I was now ready for the taking. My eyes enlarged as I watched him climb atop of me and lower his cock towards my cunt. I gasp as his cock began parting my lips. In the back on my mind I wondered if I could take all of his meat inside of me without pain. Tom was being gentle with me. He held his cock firmly against my outer lips awaiting for my body to adjust to his presence. I felt him slowly work himself into me. At one point I felt a sharp pain. That must have been when my hymen broke. The next thing I knew was Tom as fully inside of me and humping away. I was filled with his manhood and enjoying waht he was doing to my body. A wave of released tension filled my body. That must have been when I reached my first climax. I felt juices splash inside of me. Next I felt Tom's cock throb wildly and hot spurm shoot deel inside me. Tom rested atop of me till his manhood softened and slipped from my cunt. Hope that teaches you a lesson to leave my stuff alone, Susan said. Well it sisn't. Tom and I got it on several times more. Each time we screwed he would tell me how much he loved me more than my sister! Lisa
