The mission had finally ended. After months of radio silence, Krillin's small spaceship touched down in the backyard of their quiet home just outside West City. He was exhausted, bruised, and beaming with pride — he'd helped stop another galactic threat, saved lives, and couldn't wait to see his wife and daughter again. He pictured 18's cool smile, maybe a tight hug, and later… some long-overdue gentle lovemaking.
What he didn't expect was the heavy scent of sex still lingering in the air when he stepped inside.
"18? Marron? I'm home!" Krillin said.
Marron was at a friend's house for the night — 18 had made sure of that. The house was dimly lit. From the bedroom came the sound of running water and soft, satisfied humming.
Krillin pushed the door open.
Android 18 stood in front of the full-length mirror, freshly showered but still flushed. Her blonde hair was damp and tousled. She wore nothing but a loose white tank top that barely contained her massive breasts, the thin fabric clinging to her curves. Her ass — still slightly red from repeated slapping — peeked out from under the hem. A faint trickle of thick white fluid slowly leaked down her inner thigh from between her cheeks.
She turned, blue eyes locking onto her husband. There was a mix of guilt, lingering arousal, and something dangerously smug in her expression.
"Krillin… you're back early."
He froze. His eyes dropped to the trail of cum running down her leg. "18… what… what happened? Are you hurt?"
She let out a soft, almost mocking laugh and stepped closer, hips swaying. "Hurt? No, Krillin. I'm not hurt." She reached down casually and wiped a finger through the leaking semen, then brought it to her lips and licked it clean right in front of him. "Mmm. Still warm."
Krillin's face went pale. His small hands clenched at his sides. "That's… that's not mine. Who—?"
Before he could finish, the front door opened again. Heavy footsteps echoed through the house. Jax — the tall, dark-skinned, muscular warrior from the alley — strolled in like he owned the place, shirtless, sweat still glistening on his broad chest. His massive cock, even soft, hung heavily between his legs, far thicker and longer than Krillin's had ever been.
Jax grinned down at the much shorter man. "Hey, short stuff. You must be the husband. Nice to finally meet you."
18 walked over to Jax without hesitation, pressing her body against his side. One of his large hands immediately slid down to grope her ass possessively, squeezing the cheek that still bore faint red handprints from earlier.
Krillin's voice cracked. "18… tell me this isn't what it looks like. We're married. I love you. I was out there fighting for us—"
"I know you were," she said, her tone softening for a moment before turning colder, more teasing. "And I do love you, Krillin. You're sweet. You're kind. You're the father of my daughter. But…" She glanced down at the obvious bulge in Jax's pants, then back at her husband's much smaller frame. "You've never been able to fuck me the way I need. Not even close."
Jax chuckled and pulled 18 in for a deep, sloppy kiss right in front of Krillin. She moaned into it, her hands roaming over his muscular chest while Krillin stood there, stunned and humiliated.
When they broke apart, 18 looked back at her husband, eyes half-lidded with lingering lust. "Tonight in the alley… he fucked my ass so hard I came over and over. His cock is too big for my tiny hole, but I kept begging for more anyway. I told him it was too much… and then I told him not to stop."
Krillin felt tears prick at his eyes, but something else stirred too — a twisted, shameful arousal he couldn't deny. His own modest erection twitched in his pants as he watched another man's cum continue to drip from his wife's well-used ass.
Jax smirked. "She's a real screamer when she's getting stretched properly. Said your dick could never do what mine does. Want to watch me go for round two? I've still got plenty left for this cheating little android slut."
18 bit her lip, glancing between the two men. Part of her felt genuine guilt — Krillin had always been loyal and loving. But the overwhelming pleasure Jax gave her had awakened something she couldn't put back. She stepped toward her husband, gently cupping his cheek.
"You can leave if you want, Krillin. Or… you can stay and watch what a real man does to your wife. I'll still come back to you afterward. I always will. But I'm not giving this up."
She leaned in and kissed Krillin softly on the forehead — a tender, almost condescending gesture — while Jax's hand stayed firmly on her ass, fingers teasing the cum-slicked entrance.
Krillin's knees felt weak. His heart pounded with pain, jealousy, and an unwanted, throbbing excitement.
He didn't leave.
Instead, he sat down on the edge of the bed, voice barely a whisper:
"…Show me."
18's smile turned predatory. She turned back to Jax, dropping to her knees as she tugged down his pants again, freeing that massive dark cock right in front of her husband's face.
"Watch closely, little man," she purred, stroking the thick shaft while looking Krillin dead in the eyes. "This is what I've been getting while you were gone. And tonight… you're going to see exactly how much I love it."
Jax groaned in pleasure as 18 took him into her mouth, the obscene wet sounds filling the bedroom while Krillin sat there, fully cucked, his own hand unconsciously pressing against the front of his pants.
The night was only just beginning.
