The sun had dipped below the horizon hours ago, painting the sky in deep oranges and purples that faded into the quiet night around their modest home on the outskirts of the city. Krillin stood in the doorway of the living room, wiping sweat from his bald head after a light training session in the backyard. Marron was already tucked in bed upstairs, her soft breathing a gentle rhythm through the baby monitor on the coffee table. The house was theirs tonight—no world-ending threats, no tournaments, just the two of them.
Android 18 lounged on the couch in nothing but one of Krillin's old orange gi tops, the hem barely reaching mid-thigh on her long, flawless legs. Her blonde hair cascaded over her shoulders, and those cool blue eyes flicked up from her magazine as he entered. A sly smile curved her lips. "Took you long enough, short stuff. I was starting to think you'd rather punch rocks than come keep your wife company."
Krillin chuckled, rubbing the back of his neck, that familiar mix of confidence and bashful charm lighting up his face. He was short, yeah—barely five feet—but years of fighting alongside Goku had carved him into a compact wall of muscle, every inch honed and ready. "Hey, a guy's gotta stay sharp. Can't have you outclassing me every time we spar." He crossed the room in a few strides, dropping onto the couch beside her. His hand found her thigh immediately, calloused fingers tracing lazy circles on smooth, synthetic-perfect skin.
18 set the magazine aside and shifted closer, her body heat—warm, alive, despite everything she'd been through—pressing against him. "Outclass you? Please. I let you win sometimes just to boost that ego." She leaned in, lips brushing his ear. "But tonight… I'm not in the mood for letting you win anything easy. I want you to take what's yours, Krillin. All of it."
Her voice was low, teasing, that signature Android 18 coolness laced with pure heat. Krillin's breath hitched. He turned his head, capturing her mouth in a kiss that started soft but deepened fast—tongues sliding, teeth nipping. "God, 18… you know exactly how to get me going," he murmured against her lips, hands sliding up under the gi top to cup her full breasts. Thumbs brushed over hardened nipples, and she arched into his touch with a soft gasp.
"Mmm, that's it," she whispered, nipping his lower lip. "Don't hold back tonight. I can feel how hard you are already." Her hand dipped down, palming the growing bulge in his training shorts. Krillin groaned, hips bucking instinctively. She squeezed gently, stroking through the fabric. "Been thinking about this all day? My strong little monk finally letting loose on his perfect wife?"
"Every damn day," he admitted, voice rough. He tugged the gi top open, exposing her completely. 18's body was a masterpiece—curves that could make gods jealous, skin glowing under the low lamp light. He bent his head, mouth latching onto one nipple, sucking hard while his hand kneaded the other. 18 moaned, threading fingers through what little hair he had on the sides of his head, holding him there.
"Yes… like that, Krillin. Suck harder. I love when you get greedy." Her free hand shoved his shorts down, freeing his thick, veiny cock. It sprang up, already leaking at the tip, shorter than some but girthy and pulsing with need. She wrapped her fingers around it, stroking slow and firm. "Look at you. So ready for me. My little fighter's cock is always so eager."
Krillin pulled back with a wet pop, eyes dark with lust. "You're killing me here, babe. Get on my lap." He didn't wait—strong arms lifted her effortlessly, despite their size difference, settling her straddling his thighs. The gi top slipped off her shoulders completely as she ground down against his shaft, slick folds sliding along his length without taking him in yet.
"Bossy tonight, huh?" 18 smirked, rolling her hips teasingly. "I like it. But remember who's stronger." She reached between them, guiding his cockhead to her entrance, then sank down in one smooth motion. They both moaned loudly—Krillin's head falling back against the couch as her tight, wet heat engulfed him completely.
"Fuuuck, 18… you're so tight. Always so perfect," he growled, hands gripping her ass, fingers digging into firm flesh. She started riding him slow at first, rising and falling, breasts bouncing with each movement. The wet sounds of their bodies meeting filled the room—slap of skin, her slick coating his shaft.
"Talk to me, Krillin," she panted, leaning forward to kiss him messily. "Tell me how good my pussy feels. How much you love fucking your android wife." Her pace quickened, thighs flexing with superhuman strength as she rode him harder.
"It's heaven," he groaned, thrusting up to meet her. "So wet, so hot… squeezing me like you never want to let go. I could stay buried in you forever." One hand left her ass to rub her clit in tight circles, making her cry out. "That's it, cum for me, 18. I want to feel you milk my cock."
Her eyes fluttered, body tensing. "Krillin—ahh—yes! Right there!" She slammed down one last time, walls clenching around him as her first orgasm hit. Juices gushed around his shaft, soaking his balls. Krillin held her through it, kissing her neck, whispering praises. "Beautiful… my perfect girl. So good for me."
But he wasn't done. As her tremors faded, he flipped them—laying her back on the couch cushions, still buried deep. "My turn to drive," he said with a grin, starting to thrust hard and deep. The couch creaked under them. 18 wrapped her legs around his waist, heels digging into his back.
"Harder, shorty," she taunted breathlessly, nails raking down his muscular back. "Show me that stamina. Fuck me like you mean it."
Krillin obliged, pounding into her with powerful strokes honed from years of battle. Sweat glistened on his bald head, dripping onto her chest. "You asked for it," he panted, angling to hit that spot inside her that made her see stars. "Gonna fill you up. Breed this tight little pussy until you're dripping my cum all night."
"Yes! Do it—cum inside me, Krillin!" 18's second climax crashed over her, back arching off the couch. Krillin followed seconds later, burying himself to the hilt with a guttural moan. Thick ropes of cum painted her walls, overflowing as he kept thrusting through it.
They collapsed together, breathing heavy, but Krillin's fighter endurance kicked in fast. He pulled out slowly, watching his seed leak from her swollen folds. "Round two in the bedroom?" he asked, already half-hard again.
18 laughed softly, pulling him into a deep kiss. "You read my mind. Carry me, husband."
He scooped her up easily, her legs wrapping around him as he carried her upstairs. The bedroom door clicked shut behind them. Moonlight filtered through the curtains, bathing the king-sized bed in silver. Krillin laid her down gently, then crawled over her, kissing down her body—neck, breasts, stomach—until he settled between her thighs.
"My favorite view," he murmured, spreading her legs wide. His tongue dove in, lapping up their mixed juices, sucking on her clit. 18's hands fisted the sheets.
"Oh god—Krillin! Your mouth… so good. Eat me out like that. Clean your mess and make me cum again." She bucked against his face, grinding shamelessly. He hummed in approval, two fingers sliding into her cum-filled pussy, curling to hit her G-spot while his tongue worked magic.
"You taste like us," he mumbled between licks. "So fucking sexy. I could do this all night." 18's thighs clamped around his head as another orgasm ripped through her, flooding his mouth. He drank every drop, not stopping until she was trembling.
"Enough teasing," she gasped, flipping them with effortless strength so she was on top again. "I want you in my mouth first." She slid down his body, taking his cock—still slick with their combined fluids—between her lips. 18's blowjobs were legendary: deep, sloppy, no gag reflex thanks to her android physiology. She swallowed him to the base, throat contracting around him.
"18—shit—that's incredible," Krillin groaned, hand gently guiding her head. "Suck it just like that. You're gonna make me cum down your throat if you keep going."
She popped off with a wicked grin, strings of saliva connecting her lips to his throbbing cock. "Not yet. I want you to fuck my tits first." She pressed her full breasts together around his shaft, sliding up and down while her tongue flicked the tip. Krillin's hips jerked, eyes locked on the sight.
"Fuck, babe… your tits are perfect. So soft, so warm." He thrust between them faster, grunting. "Gonna paint them white."
"Do it," she urged, squeezing tighter. "Cum all over your wife's chest."
He did—hot spurts landing across her cleavage and neck. 18 moaned, scooping some up to taste. "Mmm. Salty and all mine."
But the night was far from over. Krillin pulled her up, kissing her deeply, tasting himself on her tongue. He positioned her on all fours, hands gripping her hips. "Doggy this time. I love watching that ass bounce."
"Yes," 18 purred, arching her back. "Pound me deep. Make me scream your name." He slammed in from behind, the new angle letting him hit even deeper. The bed rocked with each powerful thrust—skin slapping loudly, her moans echoing off the walls.
"Krillin! Harder—fuck me harder! Your cock feels so big like this!" She pushed back to meet him, their rhythm perfect, synced from years of fighting side by side and loving just as fiercely.
"You're mine," he growled, one hand reaching around to rub her clit again. "This body, this pussy— all mine. Gonna make you cum so many times you forget your own name."
She did—three more shattering orgasms before he filled her again, collapsing over her back, both of them slick with sweat. They rolled to the side, still joined, cuddling as heart rates slowed.
"Round three?" 18 whispered after a minute, squeezing around him playfully. Her eyes sparkled with mischief and love.
Krillin laughed breathlessly, already stirring inside her. "You're insatiable. But hell yes. Cowgirl again—I want to watch you ride me while I play with these." His hands cupped her breasts.
She straddled him once more, sinking down slowly this time, savoring every inch. "Look at us," she said softly, starting to roll her hips in languid circles. "Who would've thought the big bad android and the tiny monk would end up like this? So in love… so filthy together."
"Best decision of my life," Krillin replied, thumbs circling her nipples. "I love you, 18. More than anything."
"I love you too," she breathed, leaning down to kiss him as her pace built. "Now shut up and fuck me senseless again."
They lost track of time—positions blurring: her against the headboard, him standing and holding her up (showcasing that fighter strength), even a quick shower detour where he took her from behind under the hot spray, water mixing with their releases. Dialogues flowed between them the whole time—teasing, loving, dirty, tender.
"Deeper, Krillin—yes, right there!"
"Cum with me, 18. I'm so close."
"You're my everything… don't stop."
By the time the sky began to lighten with false dawn, they lay tangled in the sheets, exhausted but glowing. Krillin's head rested on her chest, her fingers tracing patterns on his bald scalp. Cum and sweat dried on their skin, but neither cared.
"Best night in years," he murmured, kissing her collarbone.
18 smiled, pulling the blanket higher. "And we've got the whole weekend. Rest up, short stuff. Round four after breakfast."
He chuckled. "Wouldn't miss it for the world."
