Mia stared at the dog-eared paperback on the nightstand, the cover half-torn and the pages sticky in places. She flipped it open to a random spot and read the first line out loud. "He shoved his thick cock into her dripping cunt without warning." She looked up at Jake, who was leaning in the doorway with his shirt off. "What's smut?"
Jake didn't smile or explain like some teacher. He crossed the room, grabbed the book, and tossed it aside. "That's smut," he said, voice low and flat. "Now get your ass on the bed and I'll show you the real thing."
She was already wet from the words, but his tone made her thighs clench. Mia pulled her tank top over her head and dropped her shorts, leaving nothing on. Jake stripped fast, his cock already hard and heavy, the head shiny with pre-cum. He didn't kiss her first. He pushed her onto her back, spread her legs wide, and shoved two fingers straight into her pussy.
"Fuck, you're soaked," he growled, pumping them hard. "This is what smut does. Makes your cunt ready for dick." He curled his fingers against her front wall, rubbing fast until her hips jerked. Mia moaned loud, no holding back. Jake pulled his fingers out, shoved them in her mouth, and made her taste herself. "Suck. Get them clean."
She did, tongue working between his knuckles while he lined his cock up and slammed inside in one thrust. No slow build. Just the thick stretch of him splitting her open. Jake fucked like he was angry at her pussy, hips snapping, balls slapping her ass every time he bottomed out. "This is smut," he grunted. "Raw cock pounding a greedy hole. Say it."
"It's smut," Mia gasped, voice breaking as he hammered her G-spot. He reached down and rubbed her clit in rough circles, not gentle, not teasing. Just direct pressure that made her legs shake.
"Again."
"It's smut, fuck, Jake, it's smut."
He flipped her onto her stomach, yanked her hips up, and drove back in. Doggy style, no mercy. One hand fisted her hair, the other smacked her ass hard enough to leave a red print. "Tell me what you feel."
"Your cock stretching my cunt. So deep. Hurts good." The words poured out because he demanded them. Jake liked it filthy and he made her match him. He reached under and pinched her nipples, twisting until she cried out, then soothed them with his palm only to do it again.
He pulled out suddenly, flipped her again, and straddled her chest. "Open." Mia opened her mouth and he fed his cock between her lips, fucking her throat in short, shallow strokes. Spit ran down her chin. She gagged once and he pulled back just enough for her to breathe before pushing deeper. "This is smut too. Choking on dick while your pussy drips on the sheets."
When he was close he moved back between her legs, hooked her knees over his elbows, and folded her nearly in half. The angle let him grind against her clit with every thrust. Mia came first, cunt pulsing around him, a gush of wetness soaking his balls. Jake didn't stop. He fucked her through it, then pulled out and stroked his cock twice before shooting thick ropes across her stomach and tits.
He rubbed the head through the mess, smearing it over her skin. "That's what's smut," he said, breathing hard.

"Not the book. This. You covered in my load, cunt still twitching."
Mia lay there catching her breath, legs spread, body marked. Jake didn't leave. He grabbed a towel, wiped her down slow, then climbed in beside her and pulled her against his chest. His fingers traced lazy circles on her hip.
"Want me to show you again tomorrow?" he asked.
She nodded, already sore and already wanting more. "Yeah. Show me everything."
