She bought the damn thing on a whim at the back of the used bookstore. The cover was plain black with white letters that said The Best Smut Book, no author, no blurb, just that. She cracked it open on the bus home and the first page hit her like a slap: a woman on her knees sucking cock, every detail raw and filthy. By the time she got to her apartment her panties were soaked through.
She didn’t even make it to the bedroom. She dropped on the couch, shoved her hand down her jeans, and read. The words were straight filth—no romance, no buildup, just cock, cunt, come, and hard fucking. She rubbed her clit in tight circles, breathing hard, imagining the scenes. One chapter had two strangers meeting over the same book, then fucking in an alley like animals. Her fingers slipped inside herself, pumping fast while she pictured it. She came hard, thighs shaking, the book still open on her lap.
The next day she took it to the coffee shop down the street. She was halfway through a chapter about a woman getting bent over a table and railed when a guy sat across from her.
“That book’s filthy,” he said, nodding at the cover. His voice was low and rough. “I read it last month. Made me jerk off three times in one night.”
She looked up. He was built, dark eyes, stubble. No small talk. She closed the book but kept her finger between the pages.
“Which part got you off?” she asked.
“The one where she begs for it in the ass,” he said. “You at that part yet?”
She shook her head. He leaned closer.
“Want me to show you what happens next?”
They left their coffees half-finished. His apartment was two blocks away. The second the door shut he had her against it, mouth on her neck, hands yanking her shirt up. He sucked her nipples hard, biting just enough to make her gasp. She reached down and grabbed his cock through his jeans—thick, already hard.
“Get it out,” she told him.
He unzipped, pulled his cock free. She dropped to her knees right there in the hallway and took him in her mouth, no teasing. She sucked him deep, tongue working the underside, spit running down her chin. He fucked her face in short thrusts, hands in her hair.
“Fuck, that’s it,” he grunted. “Suck that cock like the book says.”
She pulled off, stood, and stripped the rest of the way. He walked her backward to the couch, spun her around, and bent her over the arm. One hand spread her ass, the other shoved two fingers into her pussy. She was dripping.
“Wet as fuck,” he said. “Just like the girl in chapter four.”
He lined up and drove in with one hard thrust. She moaned loud, pushing back against him. He didn’t start slow. He fucked her fast and deep, hips slapping her ass, balls hitting her clit every stroke. The wet sound of it filled the room. She clawed the couch cushion, pushing back to take every inch.
“Harder,” she said. “Fuck me like that book.”
He grabbed her hips and slammed into her, pace brutal. Sweat dripped off him onto her back. When he pulled out she almost complained until she felt his thumb press against her asshole, slick with her own juices.
“Chapter seven,” he said. “You ready?”
She nodded. He worked his thumb in, then two fingers, stretching her while he kept fucking her pussy. When she was loose enough he pulled out, spat on her hole, and pressed the head of his cock there. He pushed slow at first, then sank all the way in once her ass opened up. She groaned, half pain, half filthy pleasure.
He fucked her ass the same way he’d fucked her cunt—hard, steady, no mercy. One hand reached under to rub her clit. She came first, ass clenching around him, pussy pulsing. He kept going until he pulled out and shot thick ropes across her lower back and ass cheeks.
They didn’t stop there. He flipped her over, ate her pussy until she came again on his tongue, then fucked her missionary on the floor, legs over his shoulders so he could go even deeper. She talked dirty the whole time, quoting lines from the book between moans. He answered with his own filthy descriptions of what he was doing to her.
By the time they were done the sun was down. She lay on the rug, come drying on her skin, the book on the coffee table beside them. He picked it up, flipped to a dog-eared page, and read a paragraph out loud in that rough voice. Her hand drifted between her legs again.
“Round two,” he said, dropping the book and crawling over her.

“We’re not even halfway through the good parts yet.”
They kept going until the book lay forgotten on the floor and the only sounds left were skin on skin and the wet, raw noises they made together.
