The dorm hallway was empty when Maya slipped out of her room at midnight. She was twenty-one, finals over, and restless as hell. The janitor's cart sat parked by the utility closet at the end of the hall, its wheels squeaking as the older guy pushed it. His name was Rick, mid-forties, thick arms, always in that gray uniform. She had noticed him before, the way his eyes lingered when she walked by in shorts.
She followed the sound. Rick was mopping inside the closet when she stepped in and shut the door behind her. "Lock it," she said, voice low and direct.
He turned, rag in hand. "What the fuck are you doing in here, kid?"
Maya dropped to her knees on the dirty floor. "I need this. Call you master. Use me."
Rick stared for a second, then laughed once, rough. "You serious? College slut wants the janitor to own her?"
"Yes, master." She reached for his belt, yanked it open, and pulled his cock out. It was already half hard, thick and veiny. She licked the head, then sucked it into her mouth, bobbing fast and sloppy. Spit ran down her chin right away. Rick grabbed her hair and fucked her throat deeper. "That's it, take it all. Good girl."
She gagged but kept going, eyes watering. He pulled her off after a minute, cock shiny with spit. "Stand up. Strip."
Maya peeled off her tank top and shorts. No bra, no panties. Her tits bounced free, nipples stiff. Rick spun her around, bent her over the mop sink, and slapped her ass hard. "Spread those cheeks." She did it. He spit on her asshole and rubbed his cock against her wet pussy first, then pushed in balls deep in one thrust. Maya moaned loud. "Fuck me, master. Use this college cunt."
He pounded her hard, hips slapping against her ass. The sink creaked. Every thrust made wet sounds echo in the small room. Rick reached around and rubbed her clit rough with two fingers. "You gonna come on the janitor's dick? Say it."
"Yes, master. I'm your fucktoy. Make me come." She came quick, legs shaking, pussy clenching around him. Rick didn't stop. He pulled out, spit on her ass again, and shoved his cock into her tight hole. Maya gasped at the stretch but pushed back. "Deeper, master. Wreck it."
He fucked her ass steady and deep, one hand gripping her hip, the other pulling her hair. "Dirty little bitch. Calling me master like you're nothing but holes." Maya kept repeating it, voice breaking. "Master. Master. Fill me up." Rick grunted and came inside her ass, hot pulses filling her. He stayed buried until he softened, then pulled out and watched his cum leak down her thigh.
Maya turned around, dropped to her knees again without being told, and licked him clean. "Thank you, master."
Rick zipped up but didn't leave. He grabbed her by the throat, not hard, just enough to hold her still. "This ain't one time. You come find me every night this week. Same time. You call me master, you do what I say, or I stop. Got it?"
"Yes, master."
The next night she showed up wearing nothing under a short robe. Rick had her on the floor again, this time on all fours while he ate her pussy from behind, tongue fucking her until she begged. Then he flipped her and fucked her mouth until tears ran down her face. He came on her tits and made her rub it in.

"Lick your fingers clean." She did, sucking each one.
Third night he brought rope from his cart. Tied her wrists to the pipe above the sink, legs spread wide. He edged her for an hour with his fingers and tongue, stopping every time she got close. "Please, master, let me come." He finally let her, then fucked her pussy raw while she was still shaking. Maya came twice more on his cock before he filled her up.
By the end of the week she was hooked. Rick had her calling him master in the hallway once when no one was around, just to watch her blush. He bent her over a desk in an empty classroom after hours and spanked her until her ass was red, then fucked her ass again while she thanked him. "Master's property. Use me anytime."
On the last night before break she waited in the closet naked, ass up, face down on a blanket he brought. Rick walked in, locked the door, and didn't say a word at first. He just shoved two fingers in her pussy, found her soaked, and added a third. "Already ready for master. Good slut." He fucked her with his hand until she squirted on the floor, then replaced his fingers with his cock in her ass. He took his time, slow deep strokes, making her feel every inch. Maya kept her face down and repeated it like a chant. "Master. Master. Master owns this hole."
Rick came deep in her ass, pulled out, and had her clean him with her mouth again. Then he untied her, helped her stand, and kissed her hard for the first time. "You did good, kid. Come back next semester."
Maya smiled, cum still leaking down her leg. "Yes, master."
She walked back to her room sore, marked, and already planning the next visit. The janitor had her now, and she wanted it exactly that way.
