Henry stared at the tight skirt hugging Ava’s curves as she stepped out of her car, and raw arousal surged through his gut instantly, a hot wave that made his cock strain hard against the rough fabric of his work pants. It was just another weekday afternoon in his dimly lit garage, thick with the smell of motor oil and metal, and here came his barely-known step-niece, that petite 21-year-old he hadn’t really seen since she was a kid. Now she was a college student, long-legged, full breasts straining against a cropped top, dark hair cascading loose over her shoulders.
Henry wiped his greasy hands on a rag, trying to pull his mind back in line, but damn, that skirt rode up with every step, flashing smooth, inviting thighs. Family, he reminded himself. This is family. But his dick didn’t care, it just pressed harder against his zipper.
“Hey, Uncle Henry,” Ava said with a playful little smile, pulling open the garage door and stepping inside, her heels clicking sharply on the concrete floor. “Thanks so much for making time. My junker’s making weird noises and I have no clue what’s wrong.” She bent forward to point inside the car, and Henry’s gaze locked onto the perfect round swell of her ass, the skirt stretched so tight it looked ready to split. He swallowed hard, sweat prickling down his back, and forced his eyes to the engine instead of her body.
“No problem, sweetheart,” he muttered, voice a little rough as he stepped closer. “Show me where it’s coming from.” He leaned in beside her, catching the sweet, fresh scent of her perfume mixing with garage grime, and his cock jerked with every small move she made. Ava pointed low, her arm brushing his, sending a forbidden spark up his spine. She was his late wife’s sister’s daughter, fuck, but that only made the thrill sharper, the faint shame fueling his hunger. He reached to pop the hood, and his fingers “accidentally” grazed her hip, soft, warm flesh under thin fabric. She giggled and didn’t pull away.
“Oops, sorry,” she teased, eyes sparkling as she looked up at him. “You’re the expert here, right? I’m just a clueless college girl who can’t even change a tire.” Henry chuckled, but his brain was racing: those full pink lips… how would they feel wrapped around my cock? He shook it off, focused on the engine, but she stayed close, her breast almost pressing against his arm. The heat in the garage climbed, or maybe it was just his blood boiling. Ava leaned in nearer, warm breath ghosting his neck. “Think it’ll be expensive, Uncle? I don’t have much cash… but maybe I can pay you some other way.” She said it half-joking, but her tone dripped naive, needy heat, and Henry’s cock swelled painfully against his belt.
He met her eyes, saw the flush on her cheeks. “Don’t worry about it, Ava. Family gets the friends-and-family discount.” But inside his head the thoughts spun wild: What if I touched her… really touched her? The hesitation gnawed—the taboo of blood ties and the big age gap, but it only made him harder. They laughed, chatted about nothing, her classes, his lonely widower life—but every sentence crackled with undercurrent. Her hand brushing his arm “by accident.” His eyes dipping to her cleavage, where beads of sweat glistened. The garage felt like a sauna, and Henry knew this wasn’t just about the car anymore.
When he slid under the car to check the exhaust, Ava’s voice floated down, closer than necessary. “Is it bad, Uncle? I hear that rattle again.” She crouched, skirt hiking high enough to reveal the edge of her white cotton panties stretched tight over her ass—and a visible damp spot seeping through. His cock throbbed, aching and rigid, and he froze, staring at that wet patch, imagining how her tight young pussy must look, pink, slick, dripping. Family, the word echoed uselessly. Lust won. He crawled back out, wiped his hands, stood, too close to her body.
“Not too bad,” he said, voice low and thick, placing a hand on her shoulder like he was reassuring her. Her skin burned warm and soft under his rough fingers. She looked up with wide, innocent-yet-curious eyes. “But we should test it. Hop in and start her up.” Ava obeyed, sliding behind the wheel. Henry leaned over her to listen to the engine, his chest brushing her shoulder, inhaling the scent of her sweat and arousal. She turned the key, the rattle filled the space, but his focus was on her thighs parting on the seat, panties now clearly visible, soaked and clinging.
“Feel that?” she asked, voice breathy, glancing up at him. “It’s vibrating so much.” Henry nodded, but his hand “slipped” to her knee, smooth skin under his palm, and he left it there, tracing slow circles. The voice in his head screamed she’s your niece, too young, but her eyes begged yes, please, and his cock pulsed, already leaking pre-cum into his boxers. “Yeah… it’s vibrating,” he murmured, fingers creeping higher under her skirt until they brushed the damp edge of her panties. Ava bit her lip, breathing faster, but didn’t pull away. “Uncle Henry… that feels really good,” she whispered, playful but needy, pressing his hand deeper.
He pulled her out of the car. The garage echoed with their ragged breathing. He pinned her against the side of the vehicle, body flush to hers. Her hard nipples poked through her top against his chest; his rock-hard cock pressed insistently into her stomach. “This is wrong, Ava,” he growled, even as his hands roamed her ass, kneading soft flesh, feeling her panties grow wetter. She gave a soft, naughty laugh. “Wrong? It feels so fucking good. No one has to know.” Those words snapped something in him—the taboo thrill, the age gap, the forbidden family tie, and he kissed her neck, tasting salty sweat, while his hand dove inside her panties, sliding through slick folds, fingers sinking into her soaking pussy.
Ava moaned, hands roaming his shirt, grinding against his bulge, feeling how thick and ready he was. “Show me, Uncle,” she begged, voice shaking with lust. Henry hesitated one heartbeat, family flashed again, then unzipped. His cock sprang free, thick, red, glistening with pre-cum. She stared, licked her lips, wrapped her fingers around him, stroking slow while his fingers plunged deeper, her tight walls clenching greedily. The garage spun with oil, sex, and sweat. He couldn’t stop now—the need was too strong.
Henry lifted her onto the hood, skirt shoved up, panties yanked aside. He stared at her bare, shaved pussy—pink, swollen, dripping juices down her thighs. His cock throbbed. He rubbed the head along her slick entrance, feeling her pull him in. “You really want this?” he rasped, last shred of taboo clawing at him. Her eyes burned with innocent hunger. “Yes—fuck me, Uncle Henry,” she pleaded, teasing yet desperate. He pushed in slowly, savoring every tight, wet inch as her walls gripped him.
He started thrusting, deep, steady, her breasts bouncing under the thin top, nipples like bullets. Ava’s nails raked his back; her pussy squeezed his shaft, juices dripping onto the hood. Henry growled in pleasure, balls slapping her ass. The garage rang with wet smacks and moans—the age gap and forbidden bond only cranking the heat higher. “Your pussy’s so fucking wet, baby,” he panted, slamming harder as her legs locked around his waist. She gasped, laughing breathlessly, “Because you make me so horny, old man. Deeper!”
He flipped her around, bent her over the car, took her from behind—hands gripping her hips, cock plunging in and out of her dripping hole. Her juices coated his shaft. He gave her ass a light smack; she trembled, moans growing louder. “Harder—fuck me harder,” she begged, voice breaking with need. Henry obeyed, pounding until she shattered—pussy clamping down, gushing over his balls. That pushed him over. He pulled out, shooting thick ropes of hot cum across her ass, dripping down her thighs.
But he wasn’t done. He carried her to the workbench, laid her among the tools, climbed up. His cock hardened again at the sight of her flushed, open pussy. “Again,” she purred, guiding him back inside. This time slower, savoring—sucking her nipples while he fucked her deep. She came harder, screaming his name. Henry followed, pumping her full of cum until it leaked out when he withdrew. They collapsed, panting, slick with sweat and sex, the whole garage reeking of it.
Ava turned, kissed him softly. “That was incredible, Uncle. Our little secret.” Henry nodded, cock still half-hard, the afterglow heavy with promise. He knew this wasn’t the end, the hunger still simmered in the air.
