(One day Before isekai)
Kaito Tanaka, 18-year-old high-school senior, sat naked in his dim bedroom, the only light coming from the glowing computer monitor. His blonde-haired aunt—his legal guardian since their parents died in a car crash three years ago—had left him the house in the quiet Tokyo suburb for a late-night shopping run. The place was silent except for the wet, rhythmic slapping sounds pouring from the laptop.
On screen, a porn star with bleached-blonde hair was getting absolutely destroyed. Her thick thighs were spread wide, pink pussy lips stretched obscenely around a thick, veiny cock. Every thrust made those plump folds bulge and swallow half the shaft. Clear girl-cum mixed with the natural lube was already swirling in thick, glossy ropes around the base, dripping down to her tight little asshole. Her huge, heavy breasts—easily F-cup—were bouncing wildly with every savage slam, nipples dark and stiff, bouncing like they were trying to escape the frame.
Kaito's own cock was rock-hard, throbbing painfully against his palm. A thick bead of precum already leaked from the swollen head, glistening in the monitor's blue light. He slowly dragged his tongue along the underside of his shaft, coating every inch with a stringy trail of saliva. The wet, squelching sound made his balls tighten.
"Fuuuuck… so wet…" he whispered, voice hoarse.
His free hand gripped the base of his cock, giving it slow, lazy strokes while his eyes devoured the screen. The blonde on-screen was moaning like a cheap whore, her voice cracking.
"Aaahh…. Ahhhh pushh harder..... Push harder…"
Kaito's breath hitched. His hips jerked forward instinctively, thrusting into his own fist. The chair creaked beneath him. A single, fat drop of precum splattered onto the desk.
The wet, filthy sounds on the screen were too much. His balls drew up tight.
He was right on the edge.
The bedroom door suddenly creaked open.
Kaito's eyes snapped toward the doorway in pure panic.
His aunt—his aunt—stood there in the doorway.
She was still in her work clothes: a tight black top that hugged her full, heavy breasts and a short pencil skirt that ended high on her thick, toned thighs. Her long chestnut hair was tied back in a messy ponytail, a few strands stuck to her flushed cheeks. She had come home earlier than expected, shopping bag still in one hand, eyes wide with surprise.
Their eyes locked.
Kaito's face went white. His hand froze mid-stroke, thumb still smeared with saliva and precum. His cock—pulsing, swollen, veiny—twitched violently in his fist.
The dam broke.
"Fuuuuck—!!"
Thick, white ropes of hot cum exploded from the tip of his cock in powerful spurts. The first shot hit his own stomach, splattering across his abs with a loud, wet splurt. The second and third followed in heavy, rhythmic pulses, landing on his chest, neck, even the edge of his jaw. One fat glob landed directly on his cheek, sliding slowly down his skin. His hips bucked hard, forcing out more and more until his entire lower abdomen and thighs were glazed in his own seed. The chair beneath him was soaked. A thick rope stretched from his twitching cockhead all the way to the floor.
Kaito's mouth hung open in a silent, orgasmic "aahhh" as the last weak spurts dribbled out.
His aunt stood frozen in the doorway.
Her shopping bag slipped from her fingers and hit the floor with a soft thud.
Her eyes went wide, pupils blown. She saw everything—his flushed, cum-covered face, his rock-hard chest heaving, the massive ropes of semen still pulsing from his twitching cock, the thick white puddle spreading across his abs and dripping down to his balls.
For one heartbeat, the only sound was the wet drip-drip-drip of his cum hitting the floor.
Then her mouth opened.
The door slammed shut with a loud BANG that echoed through the silent house.
Kaito sat there, chest heaving, completely naked, covered in his own orgasm, staring at the closed door in stunned silence.
His cum was still dripping down his stomach, slowly sliding toward his softening cock, while his heart pounded so hard he could hear it in his ears.
The aunt had seen it.
All of it.
And she had slammed the door.
Kaito's flushed face twisted into a mixture of shame and lingering orgasmic aftershocks as he stared at the locked door.
