I set down my pencil gingerly, watching the colour slowly changing as the pencil grew cool. There were three small taps on my door. "What do you want Elliott?" I shouted through my door. The squeaking of the door grated against my ear drums. "Step-Bitch is gone for the weekend and she took dad with her. Figured I should tell you in case you want to have a slumber party or whatever 15-year-old girls do." My older brother Elliott said, I could practically hear the smug look on his face. He was two years my senior and very attractive. I often caught myself wondering if he too was into incest. I chuckled a little. "You just want me to invite Emma over so you two can bang. Too bad El, she has a boyfriend." I swivelled my chair around, jumping a little when I found that he was now directly in front of me, looking completely unaffected by my previous comment. I felt my pussy grow wet. God he was attractive, I could see his enormous cock through his shorts. He clearly wasn't wearing anything underneath. Dragging my eyes away from his cock, I looked into his eyes. "Why would I want Emma when I have a far more attractive woman in front of me?" He smirked, pulling me up from where I sat on my desk chair and shoving me onto my bed. Guess that answered my question. Elliott slowly crawled on top of me and began to make out with me. I kept getting wetter and wetter. He kissed down my neck, stripping me of my shirt in the process. A small blush fell across my face as I hadn't been wearing a bra. He began to slowly massage my B-cup breasts, causing a small moan to escape my mouth. He grinned. "You like that do you?" I nodded. He began to slowly suck on my left nipple, squeezing the other between his fingers. I moaned, he was good. He reached his other hand downwards towards my smooth pussy, sliding his hand into my pants and panties. He slipped a finger into my pussy and began to slowly finger me while massaging my clit with his thumb. A loud moan escaped my mouth. It felt so good I just couldn't help myself. He tried to slide in a second finger but it didn't work. I was just so tight. He stopped playing with my tits and slid the finger out. "You're so tight sis, my cock wants some of that." He said, dragging my remaining clothes off with the hand that still remained in my panties. He stood for just a moment, dropping his shorts and removing his shirt. His cock was enormous. Bigger than any I've ever seen. He noticed my awe and grinned. "What? Never seen a 12" little sister?" He crawled back over me, positioning his rock hard baby maker at my entrance. He prodded gently at my lips, causing a soft moan to escape my lips. He let just the tip slide in and out a few times before slamming every inch of his giant cock inside me. I screamed in pain as well as pleasure. I could feel him stretching out my pussy and I knew what I wanted. I wanted my pussy to milk his cock. I wanted my brother to cum inside me. I said it to him. I told him I wanted every drop of it. I wasn't on the pill, but he didn't know that. "I'm going to cum Anna. I'm gonna fill you." He blew his load inside me, each shot making me moan more than the last. He pulled out once he was done and let me clean off his cock. It tasted delicious. After I was done he slid on his clothes and walked out. I laid back and realized what I had just done. My brother had just bred me. I rested a hand on my stomach. I was screwed.
***3 weeks later***
I, Annabeth Marcia Roche, knocked on Elliott's door. My father and the Step-Bitch were out shopping. Elliott shouted for me to come in. We hadn't talked much since that day three weeks ago. There was no need for it. We hardly spoke before the... incident. I pushed open the door. I took a deep breath and told him something I wish wasn't true. I told him I'm pregnant.
