It was late, and the minutes passed slowly. Midnight had been long ago, it seemed, and yet the night remained in that timeless hollow that are the wee morning hours. The lamp beside me was burning low and I flipped the page of my textbook, shifting ever so slightly. Against my chest, Monica stirred, and for a moment the words became gibberish and all I felt was her soft breast rolling against my skin, all I smelled was the vague fragrance of her shampoo.
I watched her face as she blinked awake, her hand sliding over my waist and gripping my ass. She sniffled, and looked up at me. "Don't be mad," she said.
"I'm not mad," I said. We were whispering to each other.
Monica's eyes slid away from mine and her fingers traced circles up my chest. She kissed me just below my nipple.
"Not now," I said.
"You're mad."
I put the book down in the sheets and reached for her, but she squirmed away and swung a leg over me. She drew the covers up over her head and crawled over me, watching my eyes like some shy predator. Then she bent down, and sighed, and slid her lips against my mouth, softly tracing more circles. Her little tongue flickered out, and then it was gliding over mine. "I missed you," she whispered into my mouth.
"I missed you too," I said.
"I missed this," she said, reaching down between us and grasping my turgid cock.
I reached up and cupped her ass. Gripped it. Squeezed it. She moaned a little. "I know."
Her eyes opened, but something in my gaze made her stop. Her fingers reluctantly left my cock and she frowned. "Stop thinking so much."
"I can't help it," I said. It would have been useless to argue with her. Monica knew me well enough to know the truth.
The truth was, summer was long gone, and we hadn't seen each other for months. I'd been so busy in December I hadn't come home for Christmas, and by the time I was able to visit I was already seeing someone else. It wasn't serious, but I was guilty all the same.
"Listen," said Monica, easing against my side and laying her hand on my chest, "this is just us saying hello."
I laughed. I couldn't help it. "This is not how siblings say hello."
Monica grinned and took my jaw in her hands. She kissed me. "We do."
I rolled my eyes and grabbed my book. I used it to swat her butt as she tried to stifle a giggle, grabbing her wrist to keep her from squirming away. We ended up tangled together and I dropped the book on the floor and gathered her up in my arms. "I just don't want you acting like this was all my fault," she said as she buried her nose in my chest.
"It mostly is," I said.
She scoffed and tried to slap my arm, but she was bound up too tight to get her hands free. Instead she fought me the best way she knew how, by rubbing her naked sex against me. That always worked.
"Mm," I grunted, letting her slide away - but only so far. She turned a little, I think to try to get on top, but I twisted her, fighting her struggles and pinning her down on her stomach. "Mmph!" she grunted back as my pelvis dug into her ass. My cock, now rock hard, wedged into the crack of her ass, and I held onto her arms as she struggled harder to break free. The struggling only pushed my cock deeper into her ass, and she let out another grunt as I arched my back.
"Get off of me, big brother!" she whispered shrilly.
"No, you wanted to sleep in my bed. You're going to have to pay the price." I slid my cock up against her moist slit and pushed.
"Nn! N-no!" she moaned as loudly as she dared. She struggled even harder, and then I was in her, thrusting against each of her mock attempts to break free. "Ah! Big brother! You're inside me!" she gasped.
"Shut up," I grunted into her ear. She loved that. I cupped my palm over her mouth as she began to moan louder. She bit the skin of my fingers as I roughly grabbed her breast.
The two of us were wedged into the farthest corner of the bed, her body pinned under me, her legs open and her feet kicking against the mattress as I entered her, again and again, in fierce, wet thrusts. She shut her eyes tight and arched her neck up as I fucked her, screaming into my hand.
I'd never fucked anyone like I fucked Moni. The thought made me hard, even as it troubled me. But all that troubling, all that guilt, just added to the intensity. Monica felt it; Monica knew; and that's why Monica twisted her hips; that's why she screamed harder into my hand. She loved my cock and she loved that I loved her, and she loved playing this twisted little game.
I pulled out of her. She whirled around, and I managed to trap her flat on her back. Our positions had reversed from just a few minutes earlier. Now she lay under me and I was the predator on top.
I stared down at Monica's body, glistening and pink in the dim lamplight. Her eyes were fierce, her skin flushed red under her breasts and chin. Her nipples that I loved so much were sharp and tight, and I pinched one, making her wince. Her knees knocked helplessly against my ribs as my cock swung over her shaved pussy, dripping with our mutual juices. Her hands had been splayed against her head, and now she raised them, tentatively, to my shoulders. I watched her pillowy breasts shudder with her every breath. "J-Johnny, please...don't do this..."
I bent over her and bit her on her neck. She stifled her own cry as I sucked at her, my fingers skating over her thigh and taking a handful of flesh. "Aah!" Moni cried as my cock bumped against her clitoris. She pushed me up and looked deep into my eyes. "You can't do this," she whispered. "I'm your sister.
I cupped one beautiful breast and squeezed. Monica bit her lip and shuddered. "I'll...I'll jerk you off, if that's what you want," she said, doing her best to sound pitiful. Slowly her hand reached up. I grabbed it and put it on me. "Oh! It's so...it's so big, Johnny..." My hand still over her own, I made her stroke me, and I watched the flush in her skin crawl up her face. "Oh...Oh, Johnny... Don't. I...I shouldn't..."
"Put it in your mouth," I said.
"No," said Monica, her eyes wide. "No, Johnny. I couldn't do that!"
