She slammed the book shut and tossed it on the bed. "Is that smut?" he asked from the doorway, voice low and rough.
"Yeah," she said, already pulling her shirt over her head. "You want to stand there staring or you want to do something about it?"
He crossed the room in three steps and grabbed her by the hips, yanking her pants down hard enough that the fabric tore at the seam. "Spread your legs." She did it without argument, bending over the edge of the mattress. His fingers went straight between her thighs, two of them shoving inside her cunt without warning. She was already wet, slick coating his knuckles as he pumped them fast and deep.
"Fuck, you're dripping," he muttered. "That book got you this worked up?" He curled his fingers, hitting the spot that made her knees buckle. She pushed back against his hand, grinding down.
"Keep going," she said. "Don't stop."
He pulled his fingers out and replaced them with his cock, driving in all the way on the first thrust. The stretch burned in the best way. He fucked her hard, hips slapping against her ass, one hand fisted in her hair to hold her in place. Every stroke was rough and deliberate, the head of his cock dragging over that same sensitive spot inside her until she was gasping.
She reached down and rubbed her clit in quick circles, matching his rhythm. "Harder," she told him. "Make it hurt."
He slammed into her harder, the bed frame knocking against the wall. Sweat slicked their skin. His free hand came down on her ass, a sharp slap that left heat blooming across the flesh. She moaned and clenched around him.
"Dirty little slut," he growled. "Reading that filthy shit and then begging for cock like this." He spanked her again, then reached around to take over rubbing her clit himself, fingers moving fast and rough.
She came with a choked cry, pussy pulsing tight around his cock. He didn't slow down. He kept fucking her through it, chasing his own release until he buried himself deep and came with a low groan, filling her up.
They stayed like that for a minute, breathing hard. Then he pulled out and flipped her onto her back. "We're not done," he said, already pushing her knees apart again. "Open up."
His mouth went straight to her cunt, tongue licking through the mess he'd made. He sucked on her clit, then fucked her with his tongue, tasting himself and her together. She grabbed his hair and held him there, rocking against his face until she came again, thighs shaking.
He climbed up her body and shoved his cock back inside her while she was still twitching. This time he went slower but deeper, grinding his pelvis against hers on every thrust. "Tell me what that book said," he demanded. "Tell me what got you so wet."
She told him, voice ragged, describing every explicit scene she'd just read. He listened, eyes dark, and fucked her in time with the words. When she got to the part about being pinned and used, he pulled out, flipped her onto her stomach again, and took her from behind once more, one hand pressing her face into the mattress.
They went at it until both of them were sore and shaking, bodies slick with sweat and come. When he finally pulled out for the last time, he dragged two fingers through the mess between her legs and pushed them into her mouth. She sucked them clean without being told.

He collapsed beside her. "So," he said after a minute, "is that smut?"
She laughed, hoarse. "Yeah. You want to read the next chapter?"
He rolled on top of her again, already hard. "Later."
