She knelt on the bedroom floor, naked, thighs spread wide, her wedding ring glinting under the lamp as she looked up at him. Marcus stood over her, thick black cock already half-hard and heavy, the head dark and swollen. "Open that married mouth, slut," he growled. Lisa didn't hesitate. She leaned forward and took him in, lips stretching around the girth, tongue flattening to slide along the underside as she sucked him deeper.
Her husband, Dan, sat in the corner chair, cock straining against his pants but untouched. He watched his wife bob her head, spit dripping down Marcus's shaft onto her tits. "That's it, take it all," Marcus ordered, gripping her hair. He thrust forward, pushing past her throat until her nose pressed against his abs. Lisa gagged wetly but stayed locked on him, eyes watering, throat working around the invasion.
Marcus pulled out and slapped his cock across her face. "Tell your husband what you are."
Lisa's voice came hoarse. "I'm your sex slave. Your black cock whore. Dan's wife belongs to you now."
Marcus grinned and shoved her onto all fours on the bed. He spread her ass cheeks and spat on her asshole, then pressed his cockhead against her pussy instead. "Beg for it."
"Please fuck me," she moaned. "Shove that big black cock in your slave's cunt. Ruin me in front of my husband."
He slammed in deep on the first stroke. Lisa cried out, body jerking as he stretched her wide. Marcus didn't ease up. He fucked her hard and steady, balls slapping her clit with every thrust, the wet sounds of her soaked pussy filling the room. Dan's breathing grew ragged from the chair, but he stayed silent, watching his wife's tits swing and her back arch under the pounding.
Marcus reached down and grabbed her throat from behind, pulling her upright so her back pressed to his chest. "Look at him while I use you." He kept driving up into her, one hand pinching a nipple hard enough to make her yelp. "Tell him how much better black cock feels."
"So much better," Lisa gasped, voice breaking as another thrust hit her deep. "His cock owns me. I can't stop coming on it. I'm his slave."
Marcus flipped her onto her back, legs pushed to her shoulders.

He hammered into her, sweat dripping from his chest onto her belly. Lisa's hands clawed at the sheets, mouth open in a constant stream of filthy moans. "Harder, Master. Breed your slave. Fill my married pussy."
He did. Marcus buried himself to the root and unloaded, thick ropes of cum pumping into her. Lisa came with him, pussy clenching and milking every drop, her whole body shaking. When he pulled out, cum leaked from her stretched hole down her ass crack.
Marcus pointed at Dan. "Clean her up. With your mouth."
Dan dropped to his knees without argument. He buried his face between Lisa's thighs and licked, tasting Marcus's load mixed with her juices. Lisa held his head there, grinding against his tongue. "Swallow it all, cuck. That's your job now."
Marcus watched for a minute, then grabbed Lisa's hair again. "Not done yet, slave. On your knees. Suck me hard so I can take your ass."
She obeyed instantly, slurping his softening cock back into her mouth, working it with tongue and hands until it stiffened again. Marcus bent her over the edge of the bed, spat on her asshole once more, and pressed in slow but relentless. Lisa whimpered at the burn, then pushed back, taking him inch by inch until he was balls-deep in her ass.
He fucked her there with the same raw force, one hand fisting her hair, the other slapping her ass red. "This hole's mine too. Say it."
"My ass belongs to your black cock," she panted. "I'm nothing but a hole for you to use."
Dan stayed on the floor, watching every thrust, every slap, every time Lisa begged for more. Marcus came again, flooding her ass. He pulled out and let Dan lick that clean as well.
Later, when Marcus left, Lisa stayed on the bed, cum still leaking from both holes, body marked with handprints and bites. Dan crawled up beside her. She smiled at him, lazy and satisfied. "Tomorrow he's bringing a friend. You'll watch them both use your wife. You'll thank them for it."
Dan nodded, already hard again. Lisa reached down and stroked him once, then stopped. "No. You don't get to come until they say so. You're their slave too now."
She closed her eyes, already drifting, owned and used exactly the way she wanted. The next day couldn't come fast enough.
