She asked it flat out while we were sitting on my couch, legs tucked under her, phone in hand. "What does smut mean?" I looked at her and didn't bother with definitions from some dictionary. I leaned over, grabbed her wrist, and pulled her closer until her mouth was inches from mine. "It means I'm going to fuck you until you can't say anything but yes and harder."
Her eyes went wide but she didn't pull away. I yanked her shirt up and off, no slow teasing, just fabric gone so I could get my hands on her tits. They were soft and heavy in my palms. I squeezed hard, thumbs dragging over her nipples until they stiffened. "Smut means I tell you to spread your legs and you do it without asking why." She shifted, knees parting on the cushions. I shoved my hand down the front of her shorts, found her already wet through her panties, and rubbed two fingers straight over her clit. She gasped and pushed against my hand.
I didn't ease into it. I dragged her shorts and underwear down in one move, left her bare from the waist down, and pushed her thighs wider. "Look at this cunt," I said, voice low. "Already shiny. Smut means you get off on the words and then you get off on the real thing." I slid two fingers inside her without warning. She was tight and hot, clenching around them right away. I pumped them deep, curling to hit the spot that made her hips jerk. Her breath came faster. I added a third finger and fucked her with them until she was soaking my hand and the couch.
She reached for my belt. I let her open it, pull my cock out. It was already hard, thick in her grip. "Smut means you suck it because I tell you to," I said. She dropped to her knees on the floor between my legs and took me in her mouth. No hesitation. She sucked the head first, tongue flat and wet, then took more, working down the shaft until her lips met her fist. I put a hand on the back of her head and pushed her further, not enough to choke her but enough to make her take it deeper. Spit ran down my balls. She gagged once and kept going.
I pulled her up after a minute, bent her over the arm of the couch, and kicked her feet apart. "Smut means I fuck you raw and you beg for it." I lined up and shoved inside her in one thrust. She cried out, pussy gripping me tight. I didn't give her time to adjust. I started pounding, hips slapping against her ass, balls swinging. Each stroke went all the way in. Her tits swung under her. I reached around and rubbed her clit in rough circles while I fucked her. She pushed back into every thrust, moaning loud now.
I flipped her onto her back on the couch, hooked her legs over my shoulders, and drove in again. Deeper this way. I watched my cock disappear into her wet hole, stretching her. "Say it," I told her. "Tell me what smut means." She was panting, eyes glassy. "It means… fuck me harder." I did. I slammed into her until the couch creaked and her pussy started fluttering around me. She came hard, back arching, cunt pulsing and flooding. I kept fucking her through it, not slowing down.
When she stopped shaking I pulled out, flipped her again, and pressed her face into the cushions. I spread her ass cheeks and pushed back into her pussy from behind, even rougher. One hand fisted her hair, the other reached under to pinch her clit. "Smut means you take it however I want," I growled. She nodded into the cushion, ass pushing back. I fucked her until my balls tightened and I came deep inside her, pumping thick ropes while she moaned and squeezed me.
We didn't stop there. I pulled her into the bedroom, made her get on all fours on the bed, and ate her out from behind until she came on my tongue, tasting my own cum mixed with hers. Then I fucked her again, slower but still filthy, telling her exactly what every position and every word meant. She asked the question once more, breathless, while I had her riding me. "What does smut mean?" I grabbed her hips and thrust up hard. "It means this. You, wrecked and still asking for more."
By the time we finished she was a mess of sweat and cum and shaky legs, and she knew the answer better than any book could tell her.
