Kaito sat there, frozen, his massive eight-inch cock still rock-hard and throbbing against his stomach, the head shiny and swollen, veins pulsing visibly under the skin. Cum still dotted his chest and abs in sticky white patches, cooling slowly in the warm room air. His heavy balls hung full and tight, the soft skin glistening, the neat patch of dark pubic hair matted with dried seed. His heart hammered so loud he could hear it in his ears.
Mizuki didn't move from behind him right away. Her massive breasts—those huge, soft, overflowing mounds—pressed even heavier against his naked back now that she'd sat properly, the thin white micro bikini top straining to its limit. The hard, dark-pink nipples dug into his skin through the fabric, leaving faint, warm indentations. The micro bottom barely covered her pussy lips, the thin strip of material stretched tight over her mound, outlining every curve and the deep cleft of her ass.
She leaned even closer, her hot breath brushing his ear, carrying that sweet floral scent mixed with something darker, something hungry.
"Sit on my lap," she whispered, voice low and commanding.
Kaito's mind spun. His cock twitched violently at the words, leaking a fresh bead of precum that ran down the shaft and dripped onto the sheets between his thighs.
"Aunt… what are you doing?" he managed, voice cracking, half-shocked, half-terrified.
Mizuki's full breasts pressed harder against his back as she sat up straighter, the bikini strings digging into her massive curves. Her thighs—soft and powerful—shifted behind him, the thin fabric of the micro bottom riding even higher.
"From now on, don't call me aunt," she said, voice steady, almost playful, but with an undercurrent of heat that made his balls tighten. "Call me by my name. Call me Mizuki only."
She paused, then leaned in again, her lips brushing the shell of his ear, her hot breath sending shivers down his spine.
"Watching porn is good. I also watch porn every day. I have a vibrator, a dildo… in my room. I watch porn and masturbate with it. Watching porn and masturbating isn't a crime. It's good. Let's watch porn together. I love to see full raw sex. Search this porn."
Kaito's brain short-circuited.
She… watched porn too? Every day? With a vibrator and dildo? And she wanted to watch together? With him? On him?
His cock jumped again, the thick head smearing precum all over his abs. The embarrassment and lust warred inside him—his face burned, but his dick was harder than ever.
She wants to teach me adult stuffs…
He swallowed hard, then slowly, shakily, turned his body around on the bed. His massive cock swung heavily between his legs, still rock-hard, bobbing with the movement, the foreskin pulled back slightly to reveal the fat, shiny head. He looked at her—really looked.
Mizuki sat there in that tiny white micro bikini, her enormous breasts barely contained, nipples hard and poking, her pussy lips outlined by the thin fabric, the sides of the bottom riding so high it left nothing to the imagination. Her long hair fell over one shoulder, framing her face. She patted her lap with both hands, the gesture making her huge tits jiggle heavily.
"Sit on my lap, Kaito."
He didn't argue. His cock throbbed painfully, begging for more contact. He turned fully around, straddling her lap backward, facing the laptop now. The warm, soft heat of her thighs pressed against his bare ass, her skin burning through the micro fabric. Her massive breasts pressed firmly against his back again, the bikini top squishing softly, her hard nipples rubbing against his spine with every breath. He felt the weight of her body—those huge, warm, heart-melting tits cradling him from behind like a living pillow.
It was warm. So warm. Heart-meltingly soft and heavy, the kind of comfort mixed with pure filth that made his cock leak even more.
Kaito's hands moved on autopilot. His fingers flew across the keyboard, heart racing, face still burning with embarrassment and excitement.
"Full sex… Japanese… Hiroshi and Miya… top pornstars… high quality…"
The search bar cleared and loaded. The video started automatically—brand new, high-definition, the kind that cost money for a reason.
The screen exploded with raw, uncensored Japanese porn.
Hiroshi—tall, muscular, with a thick cock that looked even bigger than Kaito's—stood over Miya. She was on her back, legs spread wide, her pussy already glistening. The camera zoomed in mercilessly on her tight little pussy lips—puffy, pink, framed by a small trimmed patch of black hair like the girl in the earlier video. Her inner folds were soft and silky, flushed darker pink from arousal, already coated in thick, clear white wetness that stretched in long, sticky strands. Her clit stood out hard and swollen.
Hiroshi's massive cock—thicker and longer than Kaito's—pressed against her entrance. The head kissed her slit, smearing precum and her own juices. Then he thrust in deep.
A slow, wet sound filled the room—schlick… schlick… schlick.
Miya's back arched. Her huge tits bounced with every impact, nipples hard as diamonds. The camera stayed locked on her pussy the entire time—close-up, no cuts.
Kaito's breath hitched. His massive cock pulsed in her hand.
Mizuki's hands moved.
One soft, warm palm wrapped around his thick shaft. Her fingers—long and delicate—started stroking him slowly, deliberately. The skin was silky, hot, sliding easily with his own precum. She rubbed up and down the entire length, from the heavy balls all the way to the swollen head, smearing the glistening precum over every inch. Her grip was firm, knowing, perfect. The wet, obscene sounds of her hand on his cock filled the room right next to the wet slapping on the screen.
"Fuuuuck…" Kaito moaned, eyes glued to the video.
Mizuki leaned over his neck, her full breasts squishing heavily against his back, her hard nipples dragging against his skin. Her hot breath was on his ear again, then her lips—soft, warm, slightly parted—pressed against his neck.
She started sucking.
Soft at first, gentle little kisses and sucks right where his pulse hammered. Then firmer, her tongue swirling, licking the spot just below his jaw, sucking lightly like she was marking him. The suction was warm, wet, perfect. Her teeth grazed once—light and teasing—before she soothed it with another kiss. Her other hand stayed wrapped around his cock, stroking faster now, the wet schlicks mixing with the sound of Hiroshi pounding Miya in the video.
Kaito's head fell back against her shoulder. Pure pleasure flooded his body. Her hand felt like heaven on his massive dick—tight, smooth, stroking every vein, every inch. The way she sucked his neck sent electric sparks straight down his spine and straight into his balls. His cock throbbed hard in her grip, the head swelling bigger, leaking more precum that she spread all over the shaft with every stroke.
On the screen, Hiroshi slammed into Miya over and over. Her pussy lips stretched wide around his thick cock, the puffy folds gripping him, inner walls visible as they fluttered. White, sticky arousal mixed with his precum coated her slit, dripping down to her ass. Every thrust made her huge tits bounce wildly, nipples hard, mouth open in loud moans.
Mizuki sucked harder on Kaito's neck, her breasts pressing down, the micro bikini top riding up so her hard nipples rubbed directly against his spine. Her hand never stopped—fast, steady, perfect strokes on his throbbing cock.
"Watch the pussy stretch… so good…" she whispered against his skin, voice husky with lust. "Feel how wet she is… your cock will feel even better…"
Kaito was lost.
His massive cock jerked in her hand, the veins throbbing, the head shiny and purple with blood. His balls tightened, drawing up close to his body. Pleasure built like a wave—hot, heavy, unstoppable.
Mizuki's fingers squeezed the base, milking him gently, her lips still sucking his neck, her massive breasts smothering his back.
The video kept going—raw, close-up, no mercy.
And Kaito's entire world narrowed down to the wet strokes of Mizuki's hand on his cock… the soft, warm sucking on his neck… and the way his aunt's huge, soft tits pressed against him while she taught him the "adult stuffs" he'd only ever dreamed of.
His hips bucked involuntarily.
His cock pulsed harder in her grip.
And the lesson had only just begun.
