She had never seen a cock that big in real life. When Mark dropped his jeans in her apartment that night, the thick, heavy shaft slapped against his thigh and her mouth went dry. It was veined, dark at the head, and already half-hard just from kissing her. She was twenty-three, had fucked a few guys before, but nothing like this. Her pussy clenched on nothing just looking at it.
“Fuck, you’re big,” she whispered, reaching out to wrap her fingers around it. Her hand didn’t close all the way. Mark grunted and pushed his hips forward, letting her stroke him slow and tight. Pre-cum leaked from the slit and she smeared it down the shaft, making it shiny and slick.
“Get on the bed,” he said, voice low and rough. She stripped fast, climbed onto the mattress on all fours the way he liked. He came up behind her, spread her ass cheeks, and dragged the fat head of his cock up and down her wet slit. She was dripping already, but when he pushed the tip against her entrance she felt the stretch immediately.
“Jesus, go slow,” she gasped. Mark didn’t answer. He just pressed forward, the broad head forcing her open. Her pussy lips spread wide around him, burning and aching in the best way. Inch by inch he sank in, and every new stretch made her moan louder. Halfway in she was panting, forehead pressed to the sheets.
“Too much?” he asked, but his hands were gripping her hips hard, keeping her in place.
“Don’t stop,” she begged. “Just… fuck, you’re huge.”
He pulled back a little, then drove in deeper. The thick ridge of his cockhead popped past her tightest spot and she cried out. Her walls fluttered around him, trying to adjust. He was so deep already and he wasn’t even all the way in. She reached down between her legs and felt how her pussy was stretched tight around the base of his shaft. Two more inches still outside.
Mark started fucking her in short, deliberate strokes, working the rest of his cock inside. Every thrust made wet, filthy sounds. Her juices ran down his balls and her thighs. When he finally bottomed out, his heavy sack pressed against her clit and she came instantly, shaking and gasping, pussy clamping down hard around the massive intrusion.
He didn’t give her time to recover. He pulled almost all the way out and slammed back in, the full length of him battering her cervix.

She screamed into the pillow, half pain, half overwhelming pleasure. Her cunt felt wrecked and used in the hottest way possible. He fucked her like that for long minutes, deep and steady, until her legs were trembling and another orgasm was building.
“Flip over,” he ordered. She rolled onto her back, spread her legs wide. He hooked her knees over his elbows and sank back into her soaked pussy in one long thrust. She could see it now, the way her stomach moved slightly every time he drove in deep. The sight made her even wetter.
“Play with your clit,” he told her. She rubbed fast circles while he pounded her, the fat cock stretching her open over and over. When she came again it was harder, her whole body locking up, pussy pulsing around him. Mark groaned, thrust deep, and she felt the hot flood of his cum pumping into her. He stayed buried, grinding against her until every drop was inside.
They stayed like that, breathing hard, his cock still thick and twitching in her stretched hole. When he finally pulled out, cum leaked out of her and down her ass. She reached down and felt how swollen and open her pussy was, fingers sliding easily into the mess he’d left behind.
“Again?” she asked, already knowing the answer. Mark’s cock was still mostly hard, glistening with their combined fluids. He flipped her onto her stomach again, spread her cheeks, and pushed back inside without warning. She moaned loud and filthy, taking every thick inch like she was made for it.
By the end of the night she was sore, leaking, and completely addicted. She had never been fucked like that before, and she already knew she’d be begging for it again tomorrow.
