I never planned on fucking my wife's dad, but the night it started, we were both drunk and alone in his garage after the family BBQ. He was 58, thick build, salt-and-pepper hair, and always had that quiet, commanding way about him. I was 32, married to his daughter for three years, and bored out of my mind with vanilla sex at home. We had cracked open a bottle of whiskey while she went to bed early.
"Ever wonder what it feels like to suck a real man's cock?" he asked out of nowhere, voice low and rough. He leaned back on the workbench, legs spread, rubbing the bulge in his jeans. I stared, heart pounding. "Don't bullshit me. I've seen how you look at me."
My mouth went dry.
"Maybe."
He unzipped and pulled out his thick, veiny dick, already half-hard. "Get over here and suck it then. No one's gotta know."
I dropped to my knees on the concrete floor. His cock smelled like sweat and musk. I licked the head, tasting pre-cum, then opened wide and took him deep. He groaned and grabbed my hair, thrusting into my throat until I gagged. "That's it, son-in-law. Suck daddy's cock like you mean it." I worked him hard, slurping and bobbing, spit running down my chin. He fucked my face until his balls tightened and he shot a thick load down my throat. I swallowed every drop.
After that night, it became regular. Whenever my wife was out, I'd drive over to his place. He'd text me simple orders: "Come suck my cock." Or "I want that ass tonight." I'd show up and he'd have me strip in the living room. He'd bend me over the couch arm, spit on my hole, and shove two fingers in dry at first just to hear me grunt. Then he'd line up his fat cock and push in slow, stretching me open inch by inch until his balls rested against mine.
"Fuck, your ass is tighter than your wife's pussy," he'd growl, pounding me deep and steady. Skin slapped loud. He'd reach around and jerk my dick in time with his thrusts until I shot ropes across the cushions. He'd keep going, using my hole until he flooded it with cum, then pull out and make me lick him clean.
One afternoon he invited me over while his wife was at work. We didn't even make it past the kitchen. He bent me over the table, yanked my pants down, and ate my ass until I was dripping and begging. Then he stood, dropped his pants, and rammed his cock straight into me. No lube beyond spit. It burned and felt so fucking good. He held my hips and fucked me hard, calling me his dirty cocksleeve, his son-in-law slut. I came without touching myself, my load splattering the floor while he kept pounding.
We got riskier. One weekend the whole family was at his lake house. My wife went to town for groceries with her mom. He found me in the boathouse and pushed me to my knees again. I sucked him while he watched the driveway through the window. When he was rock hard he turned me around, bent me over a stack of life jackets, and fucked me quick and rough. Cum leaked down my thigh when he pulled out. I had to change shorts before anyone got back.
He liked to talk dirty the whole time. "You love taking your father-in-law's dick, don't you? Bet you think about it when you're fucking my daughter." I'd moan yes around his cock or while he drilled my prostate. He'd make me say it louder: "I'm your gay fucktoy. Use my hole." Then he'd reward me by pounding until I shot again.
Months went by like that. Secret texts, quickies in the garage, long sessions when we could sneak away. He taught me how to take it deeper, how to relax and let him wreck me. Sometimes he'd edge me for an hour, fucking slow and deep, stopping every time I got close, until I was shaking and pleading. When he finally let me come it was explosive.
The last time we hooked up before things cooled off, he had me on all fours in his basement. He spanked my ass red, then sank his cock in and rode me like he owned it. "Gonna fill you up one more time," he grunted. He did, pumping load after load into me while I came untouched onto the rug. We cleaned up, went upstairs, and acted normal at dinner like nothing happened.
It stayed our secret. Raw, filthy, and exactly what we both needed.
