I came home from my shift and found her on her knees in the living room, exactly where I had left her that morning. Maya’s dark skin glistened under the low lamp, her full breasts rising and falling with each shallow breath. The collar I had buckled around her throat the night before was still locked in place, a simple strip of black leather with a silver ring that caught the light every time she swallowed.
She didn’t look up. Good girl. Two weeks ago she had been my roommate, the one who paid half the rent and left her hair products all over the bathroom counter. Now she waited in silence, thighs spread, hands clasped behind her back, pussy already wet and ready because I had trained her that way.
I dropped my keys on the table and walked straight to her. My hand fisted in her thick curls and yanked her head back so she had to meet my eyes.
“Open,” I said.
Her lips parted instantly. I shoved two fingers into her mouth and felt her tongue curl around them, sucking like she had been taught. Spit ran down her chin and dripped onto her tits. I pushed deeper until she gagged, then pulled out and wiped the mess across her face.
“Tell me what you are.”
Her voice came out hoarse. “Your black girl sex slave, Sir.”
“Again.”
“I’m your black girl sex slave.”
I kicked her knees wider and crouched in front of her. Two fingers slid straight into her cunt; she was dripping, hot, and tight. She tried not to moan but failed when I curled them against her front wall.
“You’re soaking,” I said. “You like being nothing but a hole for me to use.”
“Yes, Sir.”
I pulled my fingers out and shoved them back into her mouth so she could taste herself. While she sucked, I unzipped and freed my cock. It was already hard, thick, and veined. I rubbed the head over her lips, smearing precum.
“Suck it like the slave you are.”
She leaned forward and took me to the back of her throat in one smooth motion. I held her head with both hands and fucked her face, using her mouth the way I used her cunt later at night. Saliva poured down her chin onto her chest. Every time she gagged I pushed deeper, owning the sound. When I was close I pulled out, slapped her cheek with my wet cock, then hauled her up by the collar and bent her over the arm of the couch.
I didn’t warn her. I lined up and drove straight in, burying myself to the balls in one thrust. Maya cried out, the sound raw and broken. I gripped her hips hard enough to bruise and pounded into her, the wet slap of skin on skin filling the room. Her ass jiggled with every impact. I reached around and rubbed her clit in rough circles until her legs shook.
“Come on my cock,” I ordered.
She came hard, cunt clamping down, a broken moan tearing out of her throat. I kept fucking her through it, using her orgasm to push myself over the edge. When I came I stayed buried deep, pumping thick ropes of cum into her until it leaked out around my shaft and ran down her thighs.
I stayed inside her while she caught her breath, one hand stroking her back.
“Good slave,” I murmured. “You’re learning.”
She turned her head just enough to look at me, eyes glassy, lips swollen.
“Thank you, Sir.”
I pulled out slowly and watched my cum drip from her used hole.

Then I pushed two fingers back inside her, scooping some of it out and feeding it to her again.
“Clean it up. Every drop.”
She sucked my fingers clean without hesitation. When she was finished I clipped a leash to her collar and led her to the bedroom on her hands and knees. She crawled beside me, head down, ass swaying, the picture of total surrender.
I had turned my roommate into exactly what I wanted: a black girl sex slave who lived for my cock, my orders, and my cum. And from the way her thighs were already slick again, she wanted it just as badly.
Tonight I would fuck her ass until she sobbed my name. Tomorrow I would make her beg for it on her knees before work. Every day after that would be the same—her body, her holes, her obedience, all mine.
She was no longer my roommate. She was my property. And she had never been wetter.
