right, so I am at home, just chillin, when my sister, she's 15, comes bustin in the door in tears. She slams the door behind her and runs to her room. I'm all like, what's up with that? so I go down the hall to her room, and knock on the door. she's all like, fuck off, but I slowly open the door, and she is laying face down on her bed, crying to herself. I close the door and walk over. I sit down on the bed and put my hand on her shoulder, what's wrong? vI ask her, she says that her boyfriend dumped her because she is still a virgin, and I'm all like, what's wrong with that, but she doesn't know, but she say that that's what he said. She sits up on the bed next to me, I put my arm around her shoulders and pull her into a hug. She puts her arms around my waist and hugs me back. But then it started to get weird, she she pulled her arm back from around me and, while I was still holding her around the shoulders, she began to unbutton and unzip my pants. I just sort of froze, but went along with it at the same time, as I felt the soft touch of her hands find their way into my pants and underwear and wrap her fingers around my now throbbing cock. I pulled one arm away from her shoulders and lifted my butt to let me slide my pants down, so she could get more of my cock out. She pulled at the waistline of my pants and we both got them down to around my thighs, as she pulled my underwear down and began running her small, soft hands up and down the shaft of my cock, it felt so good. She then looked up at me, as I slid my other hand up from her shoulder to the back of her head, and pushed her down towards my cock. She greedily opened her mouth and accepted the length of my cock sliding past her lips. As I pushed her down, she began to gag as half my cock went into her mouth, just let it slide in, I whispered to her, and pushed her head down further onto my cock, until it was almost all down her throat. I released the pressure on the back of her head, and she slowly rose up, sliding her tongue around the head of my cock as she pulled all the way back up, then began to bob her mouth up and down on my cock herself. God it felt so good as I watched my little sister suck my cock. And she was so good at it too, for someone who had never had any experience before, quite the little slut. I put my hand back on the back of her head and pushed her all the way down again as I exploded my cum down her throat. She coughed and gagged as I pumped my cum into her mouth, then pushed her away. She looked up at me with the eyes of a sister hoping for praise. That was awesome, sis, I said to her, before standing up in front of her, still kneeling on the ground. I put my hand down it help her up, she took it and rose to her feet. I put my hands on her chest and felt her tits in my hands. So sweet under her school dress. I turned her around so she was facing towards her desk, and bent her over it. She looked up at me from the desk with a worried, but trusting look on her face. I slip my hands over her ass, and under the bottom of her school dress, lifting the back of it up to her hips, and sliding my hand between her legs. I could feel she was already wet, and her pussy was so hot in my fingers. I slip one of my fingers under her underwear and into her pussy, she shool and winced a little as I slid it all the way into her and began to fuck her with my finger. I spat on my other hand and began to rub that into her asshole, then used another finger from the hand I was finger fucking her with to begin to touch her asshole. First just the tip my finger tapped her asshole as I fingerfucked her, but soon it began to press against her tight asshole, then I began to push it in, lubricated by my spit. She grabbed the edge of the desk as I began to drive my finger deep into her ass. I held there for a second, with a finger all the way up both her ass and her pussy, then used my other hand to rub a mass of spit and her pussy juices onto my cock. I pulled both fingers out of her, and began to rub my cock against her pussy lips. she began to quiver and breath faster as I started to slide the tip of my cock into her wet pussy. Oh my god, oh god sis, oh my god, I cried as I slid deep into her, she was so tight, and so wet, and as I slid into her, I could hear her both moaning and whimpering as my cock drove all the way into her. How's that, sis, I said to her over her shoulder. It hurts, she gasped back. I pushed her back onto the desk and fucked her regardless, and god it was so good, and she was so tight. After coming twice inside her and about 20 minutes of hard fucking later, I asked her again over her shoulder, how does that feel? She said it was starting to feel good sort of weird too. I spat on my hand and began to rub that into her asshole again, then I pulled my cock out of her pussy and began to push it against her asshole. She just lay against the desk as I pushed my cock into her ass, gripping the sides of the desk tight. She began to cry as I started to fuck her ass, gently at first, but then harder, until I came deep in her ass. I slid out of her asshole, and turned my sister around, so she was sitting on the desk. Tears were streaming down her face, and I lifted her to her feet, then pushed her to her knees. She obligingly dropped and took my cock in her hand, rubbing it, as I pulled her head in close again. She opened her mouth and took my cock deep down her throat, as I held the back of her head and began to fuck her fack. Oh god sis, this is so good. She just knelt there and let me fuck her face. Once I came in her mouth again, I pushed her away. She fell to the ground, with my cum dripping from her every hole. There you go, sis, I said, now you're not a virgin.
