Kenji never thought that inviting his wife’s old college friend to stay with them would change his life and his marriage forever.

Derek was just visiting Japan for a few weeks. Suki had always spoken of him fondly, saying he used to help her with late-night studying, how they used to tease each other. Kenji, always trusting, never imagined there was anything beyond that.

But when Derek walked through the door, Kenji felt something shift.

He was tall, wide-shouldered, effortlessly charming. His voice boomed, his handshake crushed, and his presence filled every room like gravity. Next to Derek, Kenji felt… small. Not just physically, but everything in his voice, his confidence, his masculinity, all shrank when Derek was around.

That very night, Suki laughed at Derek’s jokes in a way Kenji hadn’t heard in years. At dinner, she leaned into his shoulder, giggling like a girl rediscovering something thrilling. And Derek? He didn’t look at Kenji unless he wanted something.

“Hey, Kenji, be a champ and bring us another bottle of sake.”

It wasn’t a request. It was the tone of a man who expected to be served.

Kenji chuckled awkwardly and got up.

What else could he do?

*****

The next night, Kenji came home late from work.

The lights were dim. Music played softly from the living room. He peeked in and froze.

Suki was curled up against Derek on the couch, wearing one of Derek’s shirts, nothing underneath, legs bare, her hand resting between his thighs. They didn’t notice him.

He backed away slowly and went to the guest bedroom. Alone.

*****

Days passed. The dynamic changed, subtly at first, then brutally. Suki started sleeping exclusively in the master bedroom. Derek moved his stuff in. Kenji didn’t resist. Not outwardly.

“It just makes sense,” Suki told him with a small, almost apologetic smile. “Derek’s a big guy. The futon would kill his back.”

“And besides,” Derek added with a smirk, “don’t you always say you sleep better alone?”

They weren’t asking.

Kenji moved into the spare room.

*****

That night, Kenji stood outside his bedroom door. But the sounds coming from inside told him this room didn’t belong to him anymore.

SLAP.

SLAP.

SLAP.

Wet, rhythmic, merciless.

Suki’s voice cut through the door like a knife through paper.

“Ohhhhh god, Derek! You’re gonna rip me open…”

Kenji’s knees weakened.

“You like that, slut?” Derek’s voice thundered. “You like being filled with a real cock?”

“YES! It’s too much, it’s too big, but I need it! I fucking love your cock!”

Kenji closed his eyes.

But her screams drilled into his soul.

*****

Inside, Suki was laid out beneath Derek like a canvas being ruined by art. Her legs shook with every deep thrust. Sweat dripped from her breasts. Her moans were raw and honest, no filter, no shame.

“Kenji’s dick… It’s not even close to yours. It’s so small. It’s so pathetic. But yours is so real… So right… So big…”

“That little babydick ever make you scream like this?” Derek asked, his hand tightening around her throat.

“Never! He’s… he’s like a toy. A sweet, tiny toy. But you?” she gasped, voice quivering with surrender. “You own me…”

Derek pulled out and let his thick shaft slap against her thigh.

SMACK.

The mark it left was as loud as the sound.

“You hear that, Kenji?” he shouted, eyes on the door. “Your wife just confessed she prefers my cock to your babydick.”

Kenji stepped back in shock. The door… it was open just enough.

Suki saw him.

She giggled.

“He’s probably jerking that pathetic little thing right now,” she said breathlessly. “I bet he dreams about having a cock like yours, Derek.”

“Nah, he doesn’t want a cock like mine,” Derek grinned. “He wants to serve a cock like mine.”

Then, he grabbed Suki’s head and shoved his cock into her mouth.

“Suck it like you’re teaching him what he’ll never have.”

She did slow, sensual, her eyes locked with Kenji’s.

*****

Later that night, Derek summoned him.

Kenji stepped into the bedroom.

It still smelled like her perfume mixed with sweat, cum, and defeat.

Suki lay in Derek’s arms, naked, glowing, satisfied in a way Kenji had never seen. She didn’t even flinch when Kenji entered.

“Clean up,” Derek said, pointing at the soaked, ruined sheets.

Kenji obeyed.

As he picked up the damp linen, Derek walked past him naked, relaxed, big cock still half-hard and still swinging heavy between his legs. It brushed against Kenji’s arm as he passed.

“You ever wonder why she moans like that with me?” Derek asked. “Because she finally knows what it’s like to be fucked by a proper man.”

“Mmmmm…” Suki sighed, eyes closed. “I didn’t know what I was missing until your cock wrecked me.” She looked at Kenji. “You were my first love, baby,” she said softly. “But Derek… Derek is my forever cock.”

Kenji said nothing.

He couldn’t.

*****

Now, Kenji sleeps on the floor. He cooks. He cleans. He folds the sheets that Derek destroys sometimes twice in one night.

Once, while Derek was pounding her hard in the living room, Suki crawled over to Kenji naked, flushed, and dripping.

She whispered in his ear while Derek’s thrusts echoed behind her: “You’ll never be enough for me again… Not after this big cock.”

And in that moment, Kenji realized

He hadn’t lost his wife to a better man.

He never had her to begin with.

 

The End.
