Kristine slammed the laptop shut but the words were already burned into her head. The archive was full of stories just like hers, raw accounts of sisters who couldn't stop fucking their brothers. She was twenty-four, he was twenty-six, and they had been sneaking around for three months. No more pretending it was an accident.
She stripped in the hallway, leaving her clothes in a trail to the bedroom. Her brother Mike was already there, naked on the bed, cock half-hard from the text she sent: "Archive open. Come use your sister."
"Fuck, look at you," he growled, pulling her down onto the mattress. His hands went straight to her tits, squeezing hard, thumbs rubbing her nipples until they ached. "You read that Kristine story again, didn't you?"
"Yeah," she panted, spreading her legs so he could see how wet she already was. "The one where the brother bends his sister over the kitchen table and fucks her raw. I want that."
Mike flipped her onto her stomach and yanked her hips up.
He spat on his cock and shoved in deep on the first thrust. Kristine moaned into the pillow, pushing back to take every inch. He gripped her ass cheeks and spread them, watching his dick disappear into her cunt.
"Dirty little archive slut," he said, pounding her hard enough the headboard slammed the wall. "You get off reading about other people doing exactly this. Now take it."
He reached under her and rubbed her clit in fast circles while he fucked her. Kristine came fast, cunt clenching around him, but he didn't stop. He pulled out, flipped her again, and shoved back in missionary so he could watch her face.
"Tell me what you want," he demanded, sweat dripping onto her chest.
"Fill me up. Come in your sister's pussy like those stories."
Mike groaned and slammed in harder, balls slapping her ass. When he came he stayed buried, pumping thick loads deep inside her until it leaked out around his cock. He didn't pull out right away. Instead he kept moving slowly, pushing his cum back in with shallow thrusts.
Kristine reached down and smeared the mess over her clit, coming again while he watched. Later they lay tangled up, his hand still possessively on her tit.
"Tomorrow we read the next one in the archive together," he said. "Then we do whatever it says."
She smiled against his neck. "Deal."
