She slammed the book shut and tossed it on the nightstand. "Why the fuck is it called smut?" she asked, voice already thick.
Her boyfriend looked up from his phone, cock already half-hard under his boxers because he knew that tone. "What?"
"That story.

It's just page after page of raw fucking. Cock in cunt, tongues on clit, cum everywhere. Why call it smut instead of just saying porn on paper?"
He grinned, shoved his boxers down, and let his dick spring free. "Because it gets you this wet." He reached between her legs and dragged two fingers through her slit. She was soaked, lips puffy, clit already swollen. "Smut makes you drip before anybody even touches you."
She spread her thighs wider. "Then stop talking and use it."
He climbed over her, grabbed his cock at the base, and slapped the head against her pussy a few times, smearing her juices over the tip. "You want it raw like the book?"
"Fuck yes."
He drove in hard, one thrust, balls-deep. She grunted, back arching. He didn't give her time to adjust, just started pounding, the wet slap of skin on skin loud in the room. Every stroke bottomed out, his heavy balls smacking her ass.
"Read me the dirtiest line you remember," he growled, hips snapping.
She fumbled for the book, voice shaking. "He bent her over and fucked her like a cheap whore, cum leaking down her thighs before he was done."
He flipped her onto her stomach, yanked her hips up, and slammed back inside. "Like this?" His hand cracked across her ass. "Tell me it's smut now."
"It's smut," she moaned, pushing back to meet every thrust. "Filthy fucking smut."
He reached under her, found her clit, and rubbed it in tight circles while he kept driving into her. She came fast, cunt clenching around his cock, juices squirting around his shaft. He didn't stop. He kept fucking her through it, fingers still working her swollen nub until she was shaking and babbling.
"Again," he ordered. "Smut makes you come twice before I fill you."
She shoved a hand between her legs to help, rubbing herself while he pounded her from behind. The second orgasm hit harder; she screamed into the pillow, pussy spasming so tight he had to fight to keep moving. When she finally went limp, he pulled out, flipped her again, and straddled her chest.
"Open," he said, tapping his slick cock against her lips. She took him in, tasting herself, sucking hard while he fucked her mouth. Spit ran down her chin. He pulled back just before he came, stroked twice, and painted her tits with thick ropes of cum.
She rubbed it into her skin, eyes half-lidded. "Still doesn't explain the word."
He laughed, low and dirty, and slid two fingers back into her messy cunt. "Because it leaves you like this. Used. Dripping. Ready for more." He curled his fingers against her G-spot and started pumping again. "Now shut up and come on my hand while I tell you exactly how I'm going to wreck your ass next."
