Kaito sat frozen on the edge of the bed, his massive cock still half-hard and twitching in his cum-smeared fist. The room smelled like sex—musky, salty, and thick with the scent of his own release. Cum had dried in sticky patches across his chest and stomach, the white strands slowly flaking off with every shallow breath. His balls hung heavy and full between his thighs, the soft skin still glistening from sweat and precum, the neat patch of dark pubic hair above them matted and tangled. His heart hammered so hard he could feel it in his throat.
Minutes passed. Five. Ten. The silence stretched, thick and suffocating.
He didn't hear the footsteps.
Mizuki had come upstairs quietly, her bare feet silent on the wooden floor. She'd changed in the bathroom downstairs—slipping into the tiny white micro bikini she'd bought on impulse after a long shift. The fabric was so skimpy it was barely there. The tiny triangle top barely covered the dark pink peaks of her nipples; the edges dug into the soft undersides of her massive breasts, pushing them up and overflowing the fabric in heavy, jiggling waves. The thin strings framed her huge, round tits like they were being offered up for inspection. Below, the matching micro bottom was a mere strip of white material that disappeared between the deepest cleft of her ass cheeks. It was so small it barely covered her pussy lips, the thin fabric stretched tight over her mound, the sides riding high enough to expose the lower curves of her ass and the top of her thighs. Every step she took made her enormous breasts bounce and sway, the hard nipples clearly outlined and straining against the fabric.
She stopped right outside his door.
He still didn't hear.
The door creaked open.
Mizuki stepped inside, closing it slowly behind her with a soft click. The room suddenly felt smaller, hotter. Her scent—light floral shampoo mixed with the faint trace of her body—hit him first. Then the sight of her.
Kaito's gaze snapped up.
His jaw dropped. His cock lurched hard in his fist, swelling to full mast in a single heartbeat. Eight thick inches of veined, throbbing meat sprang up, the head shiny and swollen, the shaft pulsing visibly with fresh blood flow. Veins stood out like ropes under the skin. The foreskin pulled back slightly, revealing the fat, dripping head. Below it, his heavy balls tightened and drew up, the skin shrinking, the pubic hair bristling.
"Holy shit…" he breathed, voice cracking.
Mizuki stood there in nothing but that obscene white micro bikini, her massive breasts heaving with each breath, the hard nipples pushing visibly against the tiny fabric. The micro bottom clung to her pussy lips like a second skin, the thin material outlining every curve, every fold, every swell. The sides were so low it left nothing to the imagination.
She wasn't angry. She wasn't disgusted.
She was… looking at him.
Kaito's brain short-circuited. How the hell had she come back like this? What the fuck was she thinking? Was she going to scream? Kick him out? Tell him to never watch porn again? Or worse… look at him like this every day?
He opened his mouth to say something—anything—but nothing came out. His cock throbbed harder, leaking a fresh bead of precum that ran down the underside of his shaft and dripped onto the bed sheets.
Mizuki took one step closer.
Then another.
Kaito's heart slammed against his ribs. He was still naked. Still hard. Still covered in his own cum. And now his aunt was walking straight toward him, her huge breasts bouncing, her pussy barely covered, those dark eyes locked on his throbbing dick.
She stopped right behind him.
Her massive tits pressed against his bare back, soft and warm and heavy. The thin fabric of the bikini top was all that separated them. Her nipples—hard as pebbles—dug into his skin through the material, leaving faint indentations.
Kaito's breath hitched. His cock jumped again, the head smearing another streak of precum across his abs.
Mizuki leaned in close. Her breath was hot against his ear, carrying the faint taste of her lipstick and the sweet scent of her body. Her full, heavy breasts squished softly against his back, the bikini strings digging into his skin.
"Let me teach you some adult stuffs," she whispered, voice low, husky, and dripping with something darker than surprise. Something that made his balls tighten and his cock throb violently.
Kaito's mind went blank.
His heart was a drum in his ears.
His massive cock pulsed like it wanted to explode right there.
And his aunt—Mizuki—was right behind him, pressing her soft, massive tits against his naked back, her breath on his neck, and she was offering to teach him "adult stuffs."
He didn't move.
He couldn't.
The room was thick with the smell of sex, cum, and now something new—her. Sweet, warm, and far too close.
His fingers loosened on his still-hard cock.
The tissue box on the nightstand was still half-open, filled with used tissues from his earlier mess.
Kaito's eyes stayed fixed on the paused porn video, but his body knew what was coming.
He was about to learn something he'd never forget.
