DADDY SWAP
Ethan had always been the quiet genius in the back of the classroom—sixteen, skinny, glasses perpetually sliding down his nose. While his classmates chased girls and parties, he chased impossible ideas in his garage workshop. He only had one friend: Jake, who was much more handsome, but very kind to him.
The ring was his masterpiece: a simple silver band etched with microscopic circuits he’d printed himself. One press of the hidden activation node, a handshake, and bodies swapped. The target’s mind slid into his old shell, blissfully unaware anything had changed, and kept living their life exactly as before. Ethan’s mind poured into the new body, memories, urges, and all flooding in like a dam breaking. And he could take the ring with him every single time. He’d tested it on stray cats first. It worked. Perfectly.
Tonight was the night he stopped playing with animals.
Jake’s dad—Mr. Reynolds—was everything Ethan had jerked off to in secret for two years. Forty-two, ex-college linebacker gone slightly softer but still thick with muscle. Broad shoulders stretching every dress shirt, dark chest hair curling at the collar, and that ass… God, that ass. Two heavy, rounded globes that filled out his khakis like they were painted on, the seam digging right between them whenever he bent over to grab a beer from the fridge. Ethan’s mouth watered every time Mr. Reynolds walked past. He’d caught himself staring so many times he was sure Jake would notice, but Jake never did. Jake just thought his nerdy best friend was awkward.
They were in the Reynolds’ living room after a Friday night pizza run. Jake had gone upstairs to grab his phone charger, leaving Ethan alone with his dad for thirty glorious seconds.
“Nice to see you, kid,” Mr. Reynolds said, standing up from the couch with that deep, rumbling voice that vibrated straight down Ethan’s spine. He offered a big, calloused hand. “You two staying out of trouble?”
Ethan’s heart hammered. His palm was slick with sweat as he reached out. “Always, sir.”
The moment their hands clasped, Ethan thumbed the tiny node on the inside of the ring.
A jolt—like static electricity but deeper—ripped through both of them. The world tilted. Colors inverted for half a second. Then it was over Ethan blinked. And he was looking down at himself.
No—looking down at his old body. Skinny arms, baggy hoodie, glasses crooked. The body that used to be his was already smiling politely at Mr. Reynolds—no, at the empty air where Mr. Reynolds had been standing. The old Ethan (now housing Mr. Reynolds’ mind) gave a casual wave.
“See you later. Pizza was great.”
And just like that, the old Ethan turned and walked upstairs like nothing in the universe had changed. Mr. Reynolds’ personality was still driving it—same easy laugh, same dad jokes queued up, same total ignorance that anything had happened.
Ethan (now inside Mr. Reynolds) stood frozen in the living room, staring at his own retreating back.
Holy fuck. It worked.
The first thing he noticed was weight. Real weight. His new arms hung heavy at his sides, biceps thick even at rest. The chest was massive, pectorals pushing against the thin cotton of the polo shirt. And between his legs… Jesus. A heavy, soft cock and low-hanging balls shifted inside loose boxers, already starting to thicken from the sheer thrill of the swap.
He flexed one hand experimentally. Thick fingers. Veins. Dark hair dusting the knuckles.
Then he felt it—the ass. Mr. Reynolds’ legendary ass. Ethan reached back slowly, heart pounding, and cupped both cheeks through the khakis. They overflowed his palms. Heavy. Round. So fucking plush yet firm. The seam of the pants was wedged tight between them, and the moment he squeezed, a low groan tore out of his new throat.
“Fuck… this is mine now,” he whispered, voice deep and gravelly.
Memories hit him like a freight train. Mr. Reynolds’ memories. The gym at 5 a.m. every morning. The way sweat soaked his tank top and made his chest hair mat down. The pride he felt when he caught his reflection in the locker-room mirror—thick traps, wide back, that shelf of an ass that made even straight guys do double-takes.
But those memories were background noise now. Ethan was in control. He locked the front door with a click, then walked straight to the downstairs bathroom, pants already tenting obscenely. The mirror showed him everything he’d fantasized about for years: square jaw dusted with stubble, thick neck, dark happy trail disappearing under the waistband.
Ethan yanked the polo off in one motion. The chest that stared back was obscene—slabs of muscle covered in a thick pelt of black hair that swirled around dark nipples already pebbled hard. He ran both hands through it, tugging, and his new cock jerked so hard it slapped against his abs.
“Goddamn,” he growled in that perfect baritone.
He shoved the khakis down next. The ass—his ass now—jiggled as the fabric peeled away. Two pale, hairy globes, perfectly round, the crack deep and shadowed. He turned sideways in the mirror and watched them bounce when he flexed. The sight made his mouth flood with spit.
He spit right into his palm and reached back. One thick finger slid between the cheeks, brushing over the tight, virgin pucker that had never been touched by anyone but its original owner. A jolt of pleasure shot straight to his cock.
“Oh my fucking God…”
He pushed inside, knuckle-deep, and the ring of muscle clamped down like it was starving. The sensation was nothing like his old skinny body. This ass was built for taking—hot, silky, greedy. He worked a second finger in, scissoring, while his other hand wrapped around the massive cock jutting out in front of him. Nine thick inches, veiny, leaking precum in fat ropes down the shaft.
He fucked himself on his own fingers, hips rolling, watching the reflection of Mr. Reynolds’ body debase itself in the bathroom mirror. The heavy balls swung with every thrust. Chest hair matted with sweat. That perfect ass swallowing his fingers to the hilt.
“Mine,” he panted, voice hoarse. “This hairy fucking ass is mine. This cock. These tits. All fucking mine.”
He came so hard his knees buckled. Thick jets of cum splattered the mirror, the sink, even the floor—Mr. Reynolds’ potent load, rope after rope, while his new hole spasmed around his fingers like it was trying to milk them.
When the last shudder faded, Ethan pulled his fingers free with a wet pop, brought them to his mouth, and licked them clean, savoring the musky taste that was now legally his.
He wiped the mirror with a towel, flushed the evidence, and pulled the khakis back up. The fabric hugged his ass like a second skin again, the seam nestling right where it belonged.
Upstairs, he could hear his old body laughing at something on Jake’s phone. Perfect. Mr. Reynolds’ mind was still playing the role of clueless dad, none the wiser.
Ethan smirked in the mirror, adjusted the silver ring on his thick finger, and gave his reflection a slow, dirty wink.
“Time to go upstairs and see what else this body can do,” he murmured.
Ethan turned from the mirror, the thick bulge in his khakis still half-hard and throbbing against the fabric. The silver ring gleamed on his meaty finger as he adjusted it, a wicked grin splitting Mr. Reynolds’ stubbled face. He already knew exactly which room he was heading to first.
The master bedroom.
He padded upstairs on heavy, powerful legs, the khakis hugging every inch of his stolen ass like a lover’s hands. Each step made the cheeks bounce and rub together, the seam grinding deliciously against his still-wet hole. He could hear faint laughter from Jake’s room down the hall—his own old voice cracking dad jokes while Jake snorted—but Ethan didn’t even glance that way. Jake was busy hanging out with “Ethan.” Perfect. Let the clueless swap keep playing pretend. This body was his now, and he had bigger, filthier plans.
The master bedroom door clicked shut behind him. Ethan locked it, heart hammering in the broad chest. Mr. Reynolds’ room smelled like him—musky cologne, faint sweat, laundry detergent. The king-sized bed was still unmade from that morning. Ethan’s new cock surged back to full mast just from the sight.
He stripped fast, yanking the polo over his head again, khakis and boxers shoved down in one motion. The heavy dick slapped up against his hairy abs with a meaty thwack, already drooling fresh precum. He kicked everything aside and stood naked in front of the full-length mirror on the closet door.
“Jesus fucking Christ,” he growled in that deep baritone, running both hands over the thick pelt covering his chest. He pinched his dark nipples hard, twisting until they ached, then slid his palms lower, over the ridges of abs gone slightly soft with age but still powerful. Lower still, until he was cupping the heavy, low-hanging balls and stroking the fat nine-inch cock in long, lazy pulls.
But it was the ass he wanted most.
Ethan turned, planted his feet wide, and bent forward slightly, arching his back like he’d seen Mr. Reynolds do a hundred times in the locker room of his memories. The mirror gave him the perfect view: two massive, hairy globes spreading apart, the deep crack shadowed and inviting. The tight pink pucker winked at him, still slick from his own spit and cum.
“Fuck, look at you,” he whispered, voice thick with lust. “That perfect dad ass… all mine.”
He spit into his palm again—twice this time—and reached back. Two thick fingers sank in easy, then three, stretching the greedy ring wide. The burn was perfect, the fullness making his cock jump and leak in heavy ropes onto the carpet. He scissored them deep, knuckle-fucking himself savagely while he watched in the mirror, hips rolling like a whore, ramming those three fingers in hard and fast, twisting viciously with every brutal thrust.
“Deeper… c’mon, you hairy bastard, take it,” he panted, fingers pistoning mercilessly, stretching the hole open wider with raw, aggressive force. His free hand reached around and jerked his cock in rough, sloppy strokes, thumb smearing the endless flow of precum over the fat head.
Memories flooded in again—Mr. Reynolds jerking off in this exact room, late at night after his wife was asleep, thinking about nothing in particular while his big hand worked that same cock. But now it was Ethan in charge, and he was thinking about everything. About bending over this bed and taking a real cock from some hot, muscled stranger at the gym. About dropping to his knees in a dark locker room and letting another hairy daddy wreck this ass until he couldn’t walk straight. About walking around the house like this every day, cock swinging, ass jiggling, owning every inch.
He kept slamming those three fingers in savagely, faster, harder, the wet slapping sounds filling the room as his hole clenched and fluttered around the rough invasion.
“Fuuuuck yes,” he groaned, loud enough he hoped someone might hear it through the wall and never know it was really his nerdy best friend making Mr. Reynolds moan like a slut. He fucked his own ass harder, three fingers buried to the hilt and pounding without mercy, while his other hand flew on his cock. The heavy balls slapped against his forearm with every thrust. Sweat matted the thick chest hair. His ass cheeks rippled and clapped as he rammed his fingers in and out.
The orgasm hit like a freight train. Ethan roared—deep, guttural, pure dad-voice—as his cock erupted. Thick, white ropes blasted across the mirror, the bed, the floor, painting everything in Mr. Reynolds’ potent load. His hole clamped and spasmed around his buried fingers, milking them like it wanted to keep them forever.
When it finally stopped, he was shaking, gasping, covered in sweat and cum. Slowly he pulled his fingers free with a wet, obscene pop, brought the slick digits to his mouth, and licked them clean, tasting the musky, filthy flavor of the body he now owned.
He wiped the mirror again, straightened up, and looked at his reflection—Mr. Reynolds’ body flushed, cock still half-hard and dripping, ass red and open from the savage fingering.
Ethan smirked, adjusted the ring on his thick finger, and licked a stray drop of cum from his lips.
