Hank was sixty-eight, thick around the middle, with a gray stubble and a permanent leer that made the younger tenants cross the street. He owned the building and collected rent in person every month, always lingering too long when the girls answered the door in shorts or thin tank tops. Most paid on time and avoided eye contact. Mia was different.
She was twenty-two, just moved in after a breakup, and the first time Hank knocked she opened wearing nothing but an oversized t-shirt that barely covered her ass. "Rent's due," he said, voice gravelly. She smiled like she knew exactly what he was thinking and handed over the cash with a wink. "Come in for a drink if you want, old man."
He stepped inside, shut the door, and grabbed her wrist. "You been parading around like that on purpose?" Mia didn't pull away. She stepped closer, pressing her tits against his chest. "Maybe. You gonna do something about it?"
Hank spun her around and bent her over the kitchen table. He yanked the shirt up, exposing her bare ass and smooth pussy. "Dirty little slut," he muttered, slapping one cheek hard. She gasped but pushed back against his hand. He dropped his pants, his thick cock already stiff and veined, and rubbed the head between her folds. "This what you wanted from the dirty old man?"
"Fuck yes," she breathed. He shoved in deep on the first thrust, stretching her tight cunt around his girth. Mia moaned loud, gripping the table edge. Hank fucked her rough and steady, balls slapping her clit with every stroke, grunting like an animal. "Tight young pussy. Been thinking about this since you moved in." He reached under and pinched her nipple through the shirt, twisting until she cried out.
He pulled out, spun her to face him, and pushed her to her knees. "Suck it clean." Mia opened wide and took his cock into her mouth, tasting her own juices. Hank held her head and thrust, fucking her throat until spit ran down her chin. "Look at you, gagging on an old man's dick." She moaned around him, one hand between her legs rubbing her clit.
When he was close he hauled her up, bent her over the couch this time, and slammed back inside. He pounded her hard, one hand fisted in her hair, the other smacking her ass red. "Gonna fill this cunt," he growled. Mia pushed back, meeting every thrust. "Do it, fill me up, you filthy old bastard."
Hank came with a roar, pumping thick loads deep inside her. He didn't pull out right away. He kept rocking, letting the cum leak out around his cock. Mia reached back and rubbed her swollen clit until she came too, clenching around him.
After that it became regular. Mia stopped paying rent in cash. Twice a week Hank showed up, sometimes with a six-pack, sometimes just his hard-on already tenting his pants.

He fucked her in every roomon the washing machine while it spun, in the shower with her leg hooked over his shoulder, on the floor like animals. He made her call him "Daddy" while he ate her pussy, tongue lapping at her clit until her thighs shook. Then he'd flip her over and rail her from behind, calling her his "filthy little cumdump."
One afternoon he brought a buddy from the bar, another old guy in his sixties. Mia didn't hesitate. She stripped on command and let them both use her mouth and cunt, switching back and forth while they talked dirty about her. "Look at this young whore taking two dirty old cocks," Hank said, slapping her ass. She came hard, moaning around the second cock in her throat.
By the end of the month Mia was sleeping in Hank's apartment more than her own. He kept her naked most evenings, bent over furniture or riding him in his recliner while he watched TV. "You like being the dirty old man's personal fucktoy?" he'd ask, and she'd grind down harder, telling him yes, begging for his load.
Hank never got softer with age. If anything he got meaner, rougher, and Mia kept coming back for more. The building stayed quiet. Rent was always on time. And every time Hank knocked on her door with that leer, she answered already wet, ready for whatever the dirty old man wanted to do to her next.
