Something about my s****r made me feel different.. SeXStoRY

It was a natural Friday and I just came back from high school, watching the hockey game with my buddy, Josh. It was funny though because he had the weirdest look on his face like something was bothering him. I asked him what was wrong and he shoved his thumb over his shoulder toward the bathroom. I looked and saw my little s****r in the bathroom, in a black tank top and jean shorts. She was putting on lip gloss or something and she was bent over the counter, perfect round ass showing quite a bit. I elbowed him slightly and he laughed. "Don't you dig her?" He asked and I shrugged. "Well, since she'd my half s****r, I guess I can say she's pretty cute." I replied and he nodded, continueing to watch the game. I looked over my shoulder at her when Josh wasn't looked at she looked at me, big blue eyes starting at me and caramel brown hair falling over her shoulder. She smiled at me and I felt my thing rise slowly. I quickly looked away, raising my left knee, trying to cover the evidence. Sitting in my room that night, I was on my laptop, kind of watching porn but I couldn't help it. After Josh had left, I'd kept watching Sydney (my s*s). I'd had sex before, but anal. It was with a girl a few years ago, but I was in grade twelve and Sydney was in grade 11. Our parent's were at their anniversary at the Keg and we were left at home, alone. A knock at my door startled me and I slammed my laptop shut. "Come in." I called and she opened the door, in a bra and jeans. "Can't quite get this shut, help?" She said to me with a confident look and walked up to me, spun around and held the back of her lacy black bra together. "Uh, sure." I was really surprised but I shut it slowly and she turned around, breasts in my face. She smiled and her bright pink lips curled and I smiled back. Then, she sat on my lap, facing me and kissed me. When her lips touched mine, I roamed my tounge with hers and she moaned. I couldn't help myself but I raised my hand to cup her boob and she smiled, taking my hand and pulling me toward the bed. "Are you sure we should be doing this...?" I asked and she brought me onto the bed and f***ed me to lay down. "Who's it gonna hurt?" She smiled, bending over and slid her white fingertips down my thighs and my cock rose. "There you go..." She smiled and rubbed her hand along the tip. I moaned and laid my head back. Then, out of nowhere, she pounced onto me and kissed me dangerously. I held her in my arms, and sat up and she held the back of my head with one hand and cupped her breast with the other. No longer could I hold it, I began to unzip her pants and she giggled, unzipping mine at the same time. She spun around, butt facing my direction and her blue eyes looked over at mine. "Anal." She whispered. I felt a rush of anticipation and I shook my pants lower, revealing my huge cock and she grinned so sexy that I slowly began to enter her ass. As I thrusted back and forth, I bent forward to press her lips against mine... The next morning, I was sitting at the kitchen table with my mom and dad. Sydney was somewhere upstairs. "Were you and Sydney okay last night?" Dad asked and I nodded. "We watched a few movies and ate popcorn." I lied and my mom smiled, glad to see our connection of a f****y. "Your father and I have to go grocery shopping and Miss. Barns is getting married today, so we'll be out for at least six hours. Would you be able to order pizza or something?" My mother asked and I shrugged and nodded. "Good." Father replied and they left half an hour later. I was walking upstairs when I heard a moaning. It was coming from Sydney's room... I peeked in through her door and saw her laying down on the bed, pink bra with her hand slip up it to cup her breast and squish her nipples, dildo in a hand and presses into her vag. I blinked and she was moving it inward and outward really fast. I stepped into the room and she snapped her head to look at me. I walked over to her, taking the dildo and began making out with her. She roamed her lips against mine with an intense compassion and then she grabbed my cock, stroking it through her hands. I lay her atop me, letting my tounge find her clit and licked vigourisly. While she sucked my cock, I knew I was going to cum any minute now and when I did, she said, "It's time. I want you to be my first Daniel, now." I spun her body around so that she could lay down. She was completly naked and so was I. I scanned her perfect round breasts, nipples pulsing and her stomach heaving. Her beautiful long cheer leader legs spread wide and face bright. "I'm going in." I said and she nodded. I slid my cock into her vagina and thrusted around. It'd been my first time making love to a girl, never thinking it would be my amazingly hot s****r. She screamed in passion and squeezed her nipples a lot. To help her, I cupped her breast and squished for her and smiled, then she brought me onto the bed, laid me down and bounced on top of me. I licked my thumb and pressed her clit, rubbing around and she groaned with pleasure. We made love for hours, and when my mom and dad came home, we smiled at them and greeted them back, acting like nothing happened, exchanging horny looks at each other.
