The door slammed shut behind them, and the cold fluorescent lights of the living room hit Mark and Lisa like a spotlight. Their parents, her sister, and his brother were already seated on the couch and chairs, eyes wide and waiting. "You two owe us," Mark's father growled, arms crossed. "Debt's due tonight, and you're paying it right here."
Mark's hands shook as he turned to Lisa. "We have to," he muttered, voice low and rough. "They'll ruin us if we don't." Lisa's face burned, but her nipples were already hard under her thin top. She nodded once, fast, and started unbuttoning her jeans.
"Strip," her mother ordered from the armchair. "Both of you. Slow enough so we see everything."
Mark yanked his shirt off first, then shoved his pants down. His cock was half-hard already, thick and twitching in the open air. Lisa peeled her top off, letting her full tits bounce free, then pushed her panties down her thighs. She was shaved smooth, and her pussy lips were already glistening. "Fuck, look at that," Mark's brother said, leaning forward.
Lisa dropped to her knees on the rug without being told. She grabbed Mark's cock and swallowed it straight down, gagging wetly on the first thrust. Spit ran down her chin as she bobbed hard, sucking loud and sloppy. Mark groaned and fisted her hair, fucking her throat in short, angry strokes. "That's it, take it all," he grunted. The family watched in silence except for the wet sounds of her mouth.
"Enough sucking," Lisa's sister snapped. "Fuck her. We want to see you stretch that cunt."
Mark hauled Lisa up and bent her over the coffee table. He kicked her legs apart, lined up, and slammed his cock balls-deep into her pussy in one thrust. Lisa cried out, back arching. He didn't wait, just started pounding her hard, hips slapping loud against her ass. Her tits swung under her with every stroke. "Goddamn, she's dripping," Mark's father muttered. "Look how wet she is getting fucked in front of us."
Lisa moaned louder, pushing back onto Mark's cock. "Harder," she begged, voice hoarse. "Make them watch you wreck me." Mark gripped her hips and drove in deeper, the table creaking under them. Her pussy clenched tight around him, juices running down her thighs. The family leaned in, eyes locked on where his thick shaft disappeared into her again and again.
Mark pulled out, flipped her onto her back on the table, and shoved back in. He hooked her legs over his shoulders and hammered her, the new angle making her scream. Her clit rubbed against his pubic bone with every thrust. "I'm gonna come," she gasped. "They're all watching me come on your cock." Her whole body shook as she squirted around him, soaking the table and his balls.
Mark didn't stop. He kept fucking her through it, then pulled out and dragged her to the floor on all fours again. "Open your mouth," he ordered. Lisa did, and he fed his cock back between her lips, letting her taste her own cum. He fucked her face while the family commented.
"She's a filthy little slut for her own family," her mother said.
Mark pulled free, hauled Lisa onto his lap facing the room, and sank her back down on his cock. She rode him reverse, bouncing hard so everyone could see her stretched pussy swallowing him. Her tits bounced wildly. Mark reached around and rubbed her clit fast and rough until she came again, thighs shaking, moaning loud enough for the neighbors.
Finally Mark grunted, slammed up deep, and unloaded. Thick ropes of cum pumped into her, overflowing and running out around his shaft. He kept her seated on him until he softened, then pushed her off so the mess was on full display.
Lisa stayed on the floor, legs spread, cum leaking from her used pussy while the family stared. Mark stood over her, breathing hard. "Debt paid," he said.
No one moved for a long moment. Then Lisa's sister stood up slowly. "Next month," she said, "you're doing it again. And this time I'm telling you exactly how."
