The evening after the Zombie Dungeon trial hung heavy with quiet triumph. Dinner with Mom had been a balm-her laughter over my mud-caked excuses for the backyard flood chasing away the All For One specter for a fleeting hour. I'd collapsed into bed early, muscles aching from the time-dilated grind, Ocean's newfound 50% mastery humming like a living current in my veins. Oceanic torrents at my call, regional water ki sensing sharpening my instincts-tools for the hero path ahead. Sleep claimed me fast, dreams swirling with green auras and crashing waves, the Gacha System's neon glow a distant, watchful eye.
It flared to life at midnight, yanking me from slumber into vertigo. No warning chime, no pull interface-just a void, cold and absolute, swallowing my apartment whole. My Saiyan physiology kicked in instinctively, ki internalizing to steady my senses, green aura flickering against the nothingness. "System? What-" The mechanical voice echoed, devoid of its usual detachment, laced with an edge I'd never heard.
System Directive: Heroic trial initiated. User teleported to parallel dimension-Earth-616, Marvel Comics continuum. Objective: Forge a bond of primal endurance to unlock return vector. Condition: Engage in extreme copulation with designated entity-Jean Grey. Duration: Four hours continuous. Impregnation required-deep insemination into womb, reinforced by abdominal compression to ensure fetal anchoring. Failure voids return; success recalibrates user's essence for multiversal resilience.
I hit the ground hard, coughing as reality snapped back. Cobblestones under my palms, the air crisp with autumn bite, streetlamps casting long shadows over a bustling Manhattan night-October 10, 2025, the system's overlay confirmed, but twisted through a comic-book lens. Skyscrapers loomed like titans, horns blaring from yellow cabs, a distant siren wailing. Earth-616. Marvel. My mind reeled-Spider-Man swinging overhead? Avengers Tower piercing the clouds? But the directive... extreme sex? Impregnation? Heat flooded my face, ki surging in panic. I'm Izuku Midoriya, quirkless turned Saiyan hero-in-training, not some... conquest machine. "This can't-System, override! I won't-"
No overrides. Entity located: Jean Grey, Xavier Institute proximity. Proceed or perish in dimensional limbo.
The interface blinked out, leaving me in the alley's gloom, hero costume intact-black-and-green bodysuit hugging my frame, Weighted Training Bands still strapped on, Kinetic Glove flexing in my fist. Dimensional Storage thrummed: 37 Senzu Beans, the Vampire Dungeon Ticket untouched. Oceanus stirred faintly in my core, The sea claims what it must, young one. Tides of fate demand surrender. I pushed down the nausea, senses flaring. A psychic hum prickled my skin-telepathic, immense, like water ki but laced with phoenix fire. Jean Grey. The Phoenix Force host, telekinetic goddess. How do I even-
Fate-or the system-decided for me. A red-gold aura bloomed blocks away, the air warping as if reality bent to her will. I broke into a run, Saiyan speed blurring the streets, leaping rooftops in bounds that cracked concrete. The Xavier Institute loomed, a gothic mansion veiled in wards, but her presence pulled like a riptide. I vaulted the perimeter wall, landing in manicured gardens, ki internalized to mask my approach. There-on a balcony overlooking the grounds, silhouetted against the moon-a woman in a flowing green cloak, auburn hair cascading like molten copper, her emerald eyes glowing faintly with inner turmoil.
Jean Grey turned as I approached, her telepathy brushing my mind like silk over steel-curious, not alarmed. "You're not from here," she murmured, voice a velvet caress that sent unwelcome shivers down my spine. Up close, she was breathtaking: lithe yet powerful, curves accentuated by a form-fitting black-and-gold uniform that hugged her like a second skin, the Phoenix emblem pulsing over her ample chest. "Who are you? And why does your mind scream of worlds beyond ours... and a compulsion I can't quite unravel?"
I froze, words tangling. "I-I'm Izuku. Midoriya. This place, it brought me here. And the only way back is... is to..." Mortification burned hotter than any ki flare. Her brow arched, a telekinetic nudge peeling back my mental shields-not invasive, but probing, tasting the directive's cold truth. Her eyes widened, a flush creeping up her neck, but no rejection-intrigue, laced with that Phoenix hunger, the cosmic entity's whisper in her veins.
"The Phoenix senses your purity," she said softly, stepping closer, her scent-ozone and wildflowers-flooding my senses. "A trial of flesh and fire. Multiversal eddies have thrown you to me... and perhaps, it's no accident." Her hand-warm, electric-traced my jaw, telekinesis loosening my costume's clasps with effortless grace. "I feel it too. A pull. Let me ease your burden, Izuku. We'll burn through it together."
Resistance crumbled under her gaze, the system's directive a inexorable current. My hands-trembling at first-found her waist, pulling her flush against me. Saiyan strength coiled, gentle but unyielding, as her lips met mine-soft, demanding, tasting of starfire. She moaned into the kiss, a low vibration that ignited my ki, green aura flickering against her red-gold nimbus. Clothes dissolved in a haze of telekinesis and ki precision-her uniform pooling at her feet, revealing porcelain skin, full breasts heaving with anticipation, her toned stomach exposed and quivering under the moonlight. My own gear vanished into Dimensional Storage, leaving me bare, my arousal-enhanced by Saiyan physiology, thick and throbbing, veined with green ki pulses-straining toward her.
Jean gasped as I lifted her effortlessly, Saiyan power making her weightless, her legs wrapping around my waist as I carried her to the balcony's shadowed alcove, a nest of cushions manifesting via her will. "Izuku," she breathed, guiding me down, her hand stroking my length-eyes widening at its girth, the Saiyan-enhanced size pulsing hotly in her grip. "So strong... so ready." I laid her back, reverent, my mouth trailing fire down her neck, over the swell of her breasts-nipples hardening to peaks as I suckled, drawing a sharp cry. Her telekinesis roamed, teasing my back, my thighs, urging me lower.
The directive loomed-extreme, impregnate deeply, squeeze to ensure. Oceanus rumbled approval, water ki stirring in my core, ready to blend with the act. I parted her thighs, her core glistening, slick with need, auburn curls framing her entrance. "Jean..." She silenced me with a finger to my lips, her mind weaving into mine-shared ecstasy, no shame, only union.
"Take me," she whispered, hips arching. I positioned myself, the broad head of my member pressing against her folds-stretching her slowly, inch by girthy inch. She was tight, velvet heat clenching around me, her walls fluttering as I sank deeper, Saiyan ki flaring to heighten every sensation. A gasp escaped her, turning to a moan-"Izuku!"-as I bottomed out, my tip breaching her cervix, nestling into the sacred depths of her womb. Her eyes flashed Phoenix-red, body arching off the cushions, telekinetic waves rippling the air.
I began to move-slow thrusts at first, building rhythm, each plunge driving me fully into her core, the slap of skin echoing softly. Her moans grew-husky, pleading-as my hips rolled, grinding against her clit, my hands roaming her body. But the peak approached, the system's demand clear. As climax built, coiling like a tidal surge, I shifted-one hand splaying over her exposed stomach, fingers pressing firmly into the soft, yielding flesh just above her mound. I squeezed-gentle pressure at first, then firmer, Saiyan strength compressing her abdomen in rhythmic pulses, ensuring every barrier yielded.
"Oh god-Izuku!" she screamed, her voice shattering the night, back bowing as the squeeze amplified the invasion, my member buried to the hilt in her womb. The pressure milked me deeper, her inner walls convulsing, drawing me in. I thrust harder-extreme, unrelenting-ki surging through my length, a green pulse that flooded her with vitality. Her screams peaked-"Izuku! Yes, deeper!"-as I squeezed again, harder, feeling the subtle shift beneath my palm, her womb contracting around my tip like a vice.
Release hit like a primordial flood. I roared, ki exploding in ecstasy, my seed erupting in thick, potent ropes-Saiyan essence, virile and endless, pumping directly into her womb's heart. The squeeze intensified-my hand kneading her stomach, compressing to force the flood deeper, ensuring not a drop escaped, anchoring the life-spark. She thrashed, nails raking my back, her own climax crashing-telekinetic bursts shattering nearby vases, Phoenix fire licking harmlessly at our joined forms. "Izuku! Fill me-ahh!" Her screams dissolved into moans, body milking every spurt, her exposed stomach taut under my grip as I felt the warmth spread, impregnation sealing in the multiversal trial.
But four hours-endless, blurring. We didn't stop. I pulled back only to flip her-onto her knees, ass high, my hands reclaiming her stomach from below, squeezing upward as I plunged in again. "Izuku!" she wailed, the name a mantra with each deep hilt, her womb yielding anew. Sweat-slicked, ki-flared, I drove into her-missionary, her legs over my shoulders for deeper angles; reverse, her back to my chest, my arms banding her waist, squeezing her belly in vise-like holds that drew guttural screams-"Izuku! More!"-as fresh loads flooded her depths, each compression ensuring saturation, the Saiyan seed taking root.
Hours melted-positions shifting in a haze of need: her riding me, breasts bouncing, my hands mauling her stomach, squeezing in time with her descent, her moans fracturing into screams as my tip battered her cervix. "Izuku-yes, breed me!" Side-by-side, spooned, my palm flat on her abdomen, pressing relentlessly as I rutted slow and deep, ki pulses syncing with her Phoenix rhythm, another climax ripping through us-seed gushing, womb overflowing yet held by the squeeze. She came undone repeatedly, telepathy broadcasting waves of pleasure that heightened mine, her screams echoing-"Izuku! In my womb-squeeze it full!"-as I compressed harder, feeling the subtle swell, the life igniting.
By the third hour, exhaustion loomed, but a Senzu Bean from Storage-36 left-restored me mid-thrust, ki roaring fresh. Jean, sensing it, laughed breathlessly, pulling me atop her once more-face-to-face, intimate, her legs locked around me. "Don't stop, my Saiyan," she purred, minds entwined. Final hour: savage, primal-thrusts like tidal crashes, my hand never leaving her stomach, squeezing in unyielding waves, drawing her screams higher-"Izuku! Impregnate me-deep!" Climax after climax, my essence flooding her womb in endless torrents, the compression ensuring every pulse embedded, the Phoenix Force weaving cosmic threads around the spark-our child, destined for legends.
As the fourth hour ticked over, Jean shuddered in afterglow, her hand over mine on her belly-the faint, ethereal glow confirming it: impregnated, deeply, irrevocably. "You did it," she whispered, kissing me softly, no regret-only sated fire. The system chimed, portal ripping open beneath us.
Directive complete. Essence recalibrated-multiversal ki affinity unlocked. Return initiated.
We tumbled through, her form fading like mist-back to her world, our bond a lingering psychic echo. I landed in my bed, dawn light filtering through curtains, body spent but whole. Mom's voice called from the kitchen-"Izuku, breakfast!"-as if no time passed. Oceanus rumbled satisfaction, Tides of creation, forged in fire. The system's glow dimmed, a new pull teasing on the horizon. I was changed-hero, father across realities, ready for whatever abyss came next.
