I slammed the comic shut but my cock was already throbbing against my jeans. "Sis, you gotta see this shit," I said, tossing the dog-eared book onto the bed between us. We were both twenty-three, stuck at our parents' place for the weekend, and I'd dug the stack of old incest comics out of the basement while looking for tools. The first one showed a brother pinning his sister against a washing machine, her legs spread wide, his thick dick buried balls-deep while she moaned "Fuck me harder, big bro."
Rachel picked it up, her cheeks flushing pink as she flipped the pages. "These are filthy. Look at this panel—her tits are out, he's licking her nipples, and it says 'Family cum is the best cum.'" Her voice got husky. She shifted on the bed, thighs pressing together. I could see her nipples poking through her thin tank top.
"Keep reading," I told her, voice low and rough. My hand dropped to my lap, squeezing my hard-on through the denim. Rachel's eyes flicked down, then back to the comic. She read aloud in a dirty whisper: "'He slid his cock into her tight pussy, claiming what was his since they were kids.' God, that's so wrong."
"Wrong feels good though, doesn't it?" I leaned closer, my breath on her neck. She didn't pull away. Instead she turned another page. The next drawing showed the sister on her knees, sucking her brother's cock, spit dripping down her chin while he gripped her hair. Rachel licked her lips without thinking.
I reached over and cupped one of her tits through the tank top, thumb rubbing her stiff nipple. "You wet yet, sis?" She nodded, biting her lip. I slid my hand down, under her shorts, and found her panties soaked. Two fingers pushed inside her hot cunt easy. "Fuck, you're dripping. Just like the girl in the comic."
Rachel moaned and spread her legs wider. "Don't stop. Read the next part to me." I kept fingering her slow and deep while I narrated the next panel. "He's eating her out now, tongue fucking her pussy while she grinds on his face. Then he flips her over and slams in from behind, smacking her ass."
She came on my fingers with a sharp cry, her walls clenching tight. Before she caught her breath I yanked her shorts and panties off, spread her thighs, and buried my face between them. Her taste was sweet and musky. I licked her clit hard, sucked on it, then drove my tongue inside like the comic showed. Rachel grabbed my hair. "Yes, just like that, you dirty fucker. Eat your sister's pussy."
I stood up, ripped my jeans open, and pulled out my cock. It was rock hard, head glistening. Rachel stared at it like the girl in the comic. "Bigger than I imagined," she said, then wrapped her lips around it. She sucked greedily, taking me deep, gagging a little but not stopping. Spit ran down my shaft as she bobbed her head.
"Look at me while you suck," I growled. Her eyes locked on mine, full of filthy heat. I fucked her mouth a few strokes, then pulled out. "On the bed. On all fours. Just like page twelve."
She scrambled into position, ass up, back arched. I grabbed her hips and shoved my cock into her wet pussy in one thrust. She was tight and hot, gripping me perfectly. "Oh fuck yes," she gasped. I pounded her hard, the way the comic brother did, skin slapping loud. Every thrust made her moan louder.
"Talk dirty like the comic," I ordered.
"Fill your sister's cunt," she panted. "Pump me full of brother cum. Fuck me like you own this pussy."
I reached under and rubbed her clit while I railed her. She came again, screaming into the pillow. I didn't stop. I flipped her onto her back, hooked her legs over my shoulders, and drove in even deeper. Her tits bounced with every slam. I leaned down and sucked one nipple hard, biting just enough to make her yelp.
"Coming again," she whimpered. Her pussy milked my cock as she convulsed. That pushed me over. I buried myself to the hilt and unloaded, thick ropes of cum flooding her. We stayed locked together, breathing hard, sweat-slick skin pressed close.
Rachel smiled lazily and reached for the next comic. "Page one says the sister rides him next. You up for round two, big brother?"
I was already getting hard again inside her. "Turn the page."
