The mission to the distant quadrant was supposed to be quick — a joint operation with the Galactic Patrol to track down a rogue bio-android threat. But delays piled up, communications went dark, and 18 was left alone in their quiet little house on the outskirts of West City. At first she handled it well. She trained harder than ever, took care of Marron, and told herself she didn't need anyone. She was Android 18, after all — stronger than almost anyone on the planet.
But the nights grew longer. The bed felt too empty. Her body, enhanced and sensitive in ways Krillin could never fully satisfy even on his best days, began to ache with frustration. She tried to ignore it. She really did.
Then she met him.
He called himself Jax — a tall, dark-skinned mercenary with a cocky grin and a body built like a Saiyan warrior. They crossed paths during one of her late-night training sessions in the ruined industrial district. He flirted shamelessly. She shot him down with her usual cold sarcasm. But when he challenged her to a spar, something stirred. He was strong. Faster than expected. And when he finally pinned her against the brick wall after a brutal exchange of blows, his hands gripping her waist with raw power, 18 felt a dangerous thrill she hadn't experienced in years.
She told herself it was just a one-time lapse. A way to blow off steam. Krillin would never know.
But now, weeks later, she was back in that same alley — bent over, skirt hiked up, white top pulled down around her waist, her massive breasts bouncing heavily with every thrust. Jax was behind her, his thick, veiny cock buried to the hilt in her tight ass, stretching her far beyond anything Krillin's modest size had ever managed.
PLAP! PLAP! PLAP!
The wet, rhythmic slapping of his heavy balls against her soaked pussy echoed off the brick walls. 18's hands pressed against the rough surface, her blonde hair disheveled, drool slipping from her parted lips as she moaned shamelessly.
"Aaah! ❤️"
"That's it… deeper!" she gasped, her voice trembling with need even as shame burned in her chest.
Jax's large hands mauled her breasts, fingers sinking into the soft, heavy flesh while he pounded her relentlessly. "Fuck, you're so tight back here," he growled, slapping her ass hard. SLAP! "Your little husband could never stretch you like this, could he?"
18 bit her lip, trying to deny it, but another powerful thrust made her cry out. "Ugh! ❤️ I'm cumming again! Nngh! ❤️"
Her body convulsed, pussy squirting messily down her thighs as her ass clenched around his massive shaft. She hated how good it felt. Krillin had always been gentle, loving… but he could never make her cum like this. Never made her feel so completely dominated.
Jax laughed darkly and pulled her hips back harder, the wet SPLASH! SPLASH! of her juices mixing with the obscene sounds of anal fucking. In the heat of the moment, 18 turned her head, glaring at him even as her eyes fluttered with pleasure.
"Holy shit! Your cock is too big for my tiny ass hole, you dumbass!"
He just grinned wider and slammed in deeper, making her squeal. "Ooooh! You won't last long!"
"Don't provoke me even more!" she snarled, but her hips were pushing back to meet his thrusts, betraying her completely.
Deep down, the humiliating truth was sinking in: every brutal thrust was a betrayal of her marriage. While Krillin was out there risking his life to protect the planet, his wife was getting her ass wrecked by a stranger's superior cock in a dirty alley. The thought made her cheeks burn with shame… and yet it also made her cum even harder.
Jax's pace grew frantic. He leaned in close, his breath hot against her ear. "Gonna fill this cheating little ass up. Bet your husband never even tried this hole, did he?"
18's only response was a broken moan as another orgasm ripped through her. The pressure was building — she could feel his cock throbbing inside her, ready to unload.
The creampie was coming. Hot, thick, and deep.
And as much as she wanted to deny it, Android 18 knew she was going to take every last drop… while her husband was light-years away, completely unaware that his perfect wife had become another man's eager anal slut.
