Mia pressed the spray can against the brick wall behind the old science building, the hiss filling the quiet night. At twenty-one, she lived for these moments, tagging her wild, dripping designs where no one else dared. The campus was dead this late, just her and the shadows. She finished the last curve of her tag when a heavy hand clamped on her shoulder.
"Caught you red-handed, girl."
She spun around. It was the janitor, the old guy everyone called Hank. Mid-fifties, thick arms, gray stubble, always pushing a mop. His eyes locked on her face, then the can still in her fingers. "Security's gonna love this. Unless you want to work something out right here."
Mia's heart slammed. She knew the drill. Graffiti meant expulsion or worse. "What do you want?" she asked, voice tight.
Hank grinned, slow and mean. "Follow me. Now."
He led her down the service stairs to the basement utility room. The door clicked shut behind them. It smelled like bleach and old sweat. Hank turned, arms crossed. "Strip. Every fucking stitch. Or I call the cops."
She hesitated, then peeled off her hoodie, jeans, bra, panties.
Standing naked under the fluorescent light, she felt his stare crawl over her tits, her shaved pussy, her ass. Her nipples tightened despite herself.
"On your knees," he ordered. "Call me Master."
Mia dropped. "Master."
He unzipped, pulled out a thick, veiny cock already half-hard. "Suck it like you mean it. Graffiti slut."
She opened her mouth and took him in. He tasted salty, musky. She bobbed her head, tongue working the underside, gagging when he pushed deeper. Hank grabbed her hair and fucked her face, hips snapping. Spit ran down her chin onto her tits. "That's it, college girl. Choke on Master's dick."
He pulled out, strings of saliva connecting them. "Stand up. Bend over that table."
She did. The metal edge dug into her hips. Hank kicked her legs apart and slapped her ass hard. "This ass is mine now." He spat on her asshole, rubbed the head of his cock against it, then shoved in. Mia cried out at the burn, but he didn't stop. He buried himself balls-deep in her ass and started pounding. Each thrust jolted her forward, her pussy dripping onto the floor.
"Fuck, tight little graffiti whore," he grunted. "You love this."
He reached around and rubbed her clit in rough circles. Mia came hard, ass clenching around him, moaning like a slut. Hank kept going until he flooded her guts with hot cum. He pulled out and made her lick him clean.
After that night it became routine. Every few days Hank texted her. She showed up at the basement door, stripped, and submitted. He fucked her in every hole, used her mouth, spanked her until her ass glowed red. Sometimes he tied her wrists with old mop strings and made her beg to come. Other times he bent her over the utility sink and railed her while the campus above slept.
One humid Thursday he brought a marker. "Write your tag on your own tits," he said. Mia scrawled the dripping letters across her breasts while he watched, then he pushed her down and fucked her throat until tears streaked her makeup. Another night he made her crawl on all fours, spray-painting a fresh tag on the floor while he fucked her from behind, calling her his dirty little vandal.
Weeks blurred. Mia stopped tagging anywhere else. The risk wasn't worth losing this. Hank owned her now. He decided when she came, how hard, where he dumped his load. Sometimes he edged her for an hour, fingers and tongue working her until she sobbed, then finally let her explode around his cock.
The last night of the semester he had her on her back on the old couch in the corner, legs spread wide. He fucked her pussy slow and deep, staring into her eyes. "You're my college girl now. My graffiti slut. Say it."
"I'm your graffiti slut, Master," she panted, coming again, pussy pulsing around him.
He filled her, then pulled out and watched his cum leak from her. "Clean it up."
Mia licked him spotless, then stayed on her knees, waiting for whatever he wanted next. Outside, the campus was quiet. Down here, the only sound was her breathing and the faint drip of a pipe. Hank patted her head like a pet.
"Same time next week, girl. Don't be late."
She smiled, already wet again at the thought.
