Chapter 7: Ben's Omnitrix Overload – Alien Breeding Tour
Ben Tennyson was sixteen again—sort of. The Omnitrix had glitched during a routine Plumber patrol, flooding his body with a cocktail of alien DNA boosters that Rick Sanchez would've called "irresponsible science porn." The result? Ben could stay transformed indefinitely, cycle through forms without timing out, and—most importantly—his human dick had been upgraded across every alien species in the database. Each form came with its own massive, species-specific cock, endless stamina, and pheromones that turned any nearby female into a dripping, begging mess.
He didn't plan it. He just… snapped.
The first one was Gwen.
They were alone in the Rust Bucket 3.0, parked on a quiet beach at sunset. Gwen had just finished lecturing him about "responsibility" when the Omnitrix beeped green.
"Gwen… I feel weird."
She rolled her eyes. "You always feel weird when—"
He hit the dial. Heatblast first—because why not start hot?
Flames roared. His body became living magma, cock a thick, glowing orange rod veined with molten cracks, dripping lava-like precum that sizzled harmlessly on the floor. Gwen's eyes widened, thighs clenching under her skirt.
"Ben… what the hell—"
He grabbed her waist with superheated hands—careful not to burn—and yanked her against him. Her shirt disintegrated in seconds from the heat. She gasped as his flaming tongue licked a trail up her neck.
"Shut up and spread."
He bent her over the table. Her panties melted away. Heatblast's cock pressed against her entrance—hot, pulsing, impossibly thick. He pushed in slow. Gwen screamed—pleasure-pain mix—as molten heat filled her. Every thrust made her inner walls flutter and clench. Steam rose where their bodies met. She came in under a minute, squirting so hard it hissed against his lava skin.
He didn't stop. He fucked her through three orgasms, then pulled out and came—thick ropes of glowing, harmless plasma-cum flooding her womb until her belly swelled slightly and excess dripped in glowing puddles.
Next form: Four Arms.
Gwen was still panting when Ben slapped the symbol again. Four massive red arms, four bulging pecs, and a cock so thick it looked like two forearms taped together. Two heavy balls the size of grapefruits swung low.
He lifted her like a doll—two arms under her thighs, two pinning her wrists above her head—and slammed her down onto his shaft. Gwen's eyes rolled back instantly. He fucked her standing, bouncing her like a fleshlight, each thrust bottoming out against her cervix. She came again, screaming his name, nails raking his chest plates.
He came buckets—four-armed strength meant four times the load. Cum poured out around his girth in thick white rivers, pooling on the floor.
Gwen collapsed against him, trembling. "Ben… you're gonna kill me…"
"Not yet."
Diamondhead next. Crystalline body, diamond-hard cock studded with harmless facets that dragged along her walls like textured perfection. He laid her on her back, spread her wide, and fucked her slow and deep—each ridge catching her G-spot until she was babbling nonsense. He came inside her again, crystalline cum sparkling as it overflowed.
Then Rath—tiger-like fury, barbed cock designed to lock in place. He mounted her from behind, growling, "You're mine, Tennyson!" Barbs flared as he came, trapping his load deep while she howled through another shattering orgasm.
Big Chill—intangible phasing cock that let him fuck her from impossible angles, sliding through walls of flesh without resistance, chilling her insides until she came so hard her breath fogged.
Jetray—long, flexible, prehensile dick that coiled inside her like a living tentacle, hitting every spot at once.
Humungousaur—massive twenty-foot form, cock the size of her forearm. He shrank just enough to fit, then railed her until the Rust Bucket rocked on its suspension.
Alien X—reality-warping cock that made her feel every possible orgasm simultaneously. She blacked out for a second from the overload.
By the time he cycled back to human, Gwen was a cum-drenched, blissed-out mess on the floor, belly slightly rounded from the sheer volume he'd pumped into her.
But Ben wasn't done.
The Omnitrix pinged—location beacons from every major female in his life.
He portaled out.
Kai Green – in her Anodite form, glowing purple energy body. Ben went Echo Echo—sonic vibrations turned his cock into a living vibrator. He fucked her mid-air, duplicating himself so four Echo Echoes railed her at once: pussy, ass, mouth, hands. She came screaming in harmonic frequencies.
Rook's sister, Shar – Revonnahgander feline grace. Ben as Fasttrack—speed-fucked her so fast she felt like one continuous orgasm. His cock blurred in and out, leaving her a quivering puddle.
Looma Red Wind – Tetramand warrior princess. Ben matched her with Four Arms again, but this time they wrestled first—brutal, sweaty grappling that ended with him pinning her and breeding her like a conquering king. Her four arms wrapped around him as he flooded her warrior womb.
Attea – Incursean frog-princess. Slimy, flexible body. Ben as Goop—liquid green cock that flowed inside her, filling every crevice, reforming to stretch her impossibly. She croaked in pleasure as he came in gallons of glowing slime.
Charmcaster – dark magic sorceress. Ben as Ghostfreak—phasing cock that fucked her soul directly while his physical form railed her body. She came so hard she accidentally summoned lightning that struck them both—pleasure overload.
Zombozo's niece (the creepy clown girl who grew up hot) – Ben as Big Chill, freezing her in ecstatic ice while he fucked her senseless.
Helen Wheels – Kineceleran speedster. Ben matched her with XLR8—frictionless speed-fucking in a blur, both of them cumming in sonic booms.
Pierce's sister (the Circuits freak) – Ben as Upgrade—merged with her cybernetic body, turning his cock into a vibrating, shape-shifting techno-dildo that hacked her pleasure centers.
Every Plumber cadet girl on base – group session. Ben cycled through forms: Rath for rough dogpile, Diamondhead for crystalline gangbang, Heatblast for a literal hot orgy. They took turns riding him, sucking him, getting filled in every hole until the training room smelled like sex and alien pheromones.
Hours later—maybe days, time was blurry—Ben staggered back to the Rust Bucket as human again.
Gwen was waiting, still naked, still leaking from every form he'd used on her.
She looked up, eyes glassy with lust and exhaustion.
"You… fucked the entire galaxy."
Ben collapsed beside her, cock finally softening.
"Yeah. Worth it."
She crawled over, kissed him slow—tasting every alien flavor still on his tongue.
"Next time… bring me along. I wanna watch."
Ben grinned, weak but wicked.
"Deal."
The Omnitrix beeped softly—ready for round two.
Somewhere in the cosmos, every female Ben had touched felt a strange, satisfied ache.
And they all smiled.
