Sarah hit the gym every Tuesday and Thursday after dropping the kids at school. At 38 she kept her body tight with squats and cardio, her ass round and her tits still perky in a sports bra. She was stretching near the free weights when he walked in. Tall, dark-skinned, built like he lived there. His name was Marcus. He nodded once, then loaded the barbell.
She watched his arms flex, the way his shorts hugged his thighs and the thick outline that pressed against the fabric. Her pussy got wet just looking. She moved to the leg press next to him and started pumping. Sweat ran down her cleavage. Marcus glanced over, caught her staring, and smirked.
"Need a spot?" he asked, voice deep and direct.

"Yeah," she said. "Help me push it."
He stepped behind her. His hands brushed her shoulders as she pressed. On the last rep his fingers slid lower, resting on her hips. "Good form," he said. "Bet you fuck just as strong."
Sarah didn't play coy. "My husband's out of town. Locker room in ten minutes."
Marcus followed her in. The place was empty at midday. She locked the door behind them. He yanked her sports bra up, freeing her tits, and sucked a nipple hard while he shoved her shorts and panties down. She kicked them off and spread her legs. His fingers went straight to her cunt, two thick digits pushing inside.
"Fuck, you're soaked," he growled. He dropped his shorts. His cock sprang out, long, veined, and dark, the head already leaking. Sarah dropped to her knees and took it in her mouth, sucking hard, gagging when he thrust to the back of her throat. Spit ran down her chin onto her tits.
He pulled her up, bent her over the bench, and slammed into her from behind. One thrust, deep and rough. Sarah moaned loud. He gripped her hips and fucked her hard, balls slapping her clit with every stroke. Her pussy stretched around that thick black cock, gripping it tight.
"Harder," she begged. "Use that dick."
Marcus pounded her, the bench creaking. He reached around and rubbed her clit fast. Sarah came quick, cunt pulsing, juice dripping down her thighs. He didn't stop. He flipped her onto her back, hooked her legs over his shoulders, and drove in again. Her tits bounced with every thrust. She grabbed his ass and pulled him deeper.
He pulled out, flipped her again, and pushed into her ass without warning. Sarah gasped, then pushed back, taking every inch. He fucked her ass raw, grunting, sweat dripping onto her back. She rubbed her clit and came again, ass clenching around him.
Marcus pulled out, spun her around, and shoved his cock back in her mouth. She tasted her own ass and pussy on him. He held her head and fucked her face until he grunted and shot thick ropes down her throat. She swallowed every drop, then licked him clean.
They dressed fast. Marcus slapped her ass on the way out. "Same time next week," he said.
Sarah smiled, still tasting him. Her legs felt weak, but she walked out satisfied, already planning the next round.
