ââââââââââââââââââââââââ
he only had another minute or two.
steam rose from the crevices of your locked bathroom; music blaring from the other side.
â[nâname]! ngângmh! nhg!âŠ.fuâfugk! right there!â the words left his mouth in an unceremonious fashion, sounding more like a broken record; he said it again, and again, repeating himself almost indulgently. a hand ghosted his twitching erection, blazing forth a sleuth of high-pitched moans.
your hands reached for the knobs, twisting it off in one swift movement.
âjust a little longer baby.â
IâI canâtâŠ! plâplease [name]! I need toâ nghm! cum!â the machinery within his body continued to spear his insides, impaling the deepest depths of his mind. with a steady flow of electronsâ curtesy of his quirk, the speed of his âtoyâ increased drastically, now entailing itself into his stomach.
âmmhg! [naâname]! IâIâm gonâgonna cum!â
he listened intently, already having memorized the audioâs contents. your voice spoke to him, shooting daggers into his body.
âdoes my good boy wanna cum?â
Denki noddedâ phonetically speaking through gritted teeth. âtes! [name] leâlemme cuhm!â
his body retreated away from the sound, his head snapping backwards at the edging.
sweat trickled from his forehead, exhaustion clawing at his hips. he pressed your shirtâ sweat-ridden and freshly usedâ further against his nose, inhaling deep breaths of your musky scent, the smell sending him overflowing with lust.
he squirmed against your sheets, moving his hands to slam your pillow over his face. ânmfghâŠ! [nâname]! mfgâghm!â he pulled the pillow awayâ vision still slightly obscured by your shirt.
âaww, Iâm hurt⊠comparing me to something as small as that.â
Denki shot up, his quirk mushing more elegant arcs of electrical surges into the machineâ it picking up enough speed to make him lurch to his side. âuhng! waâwait! wait [nâna]! wait, itâitâs not whatâwhat it looks like!â
your body coupled into his vision, the tranquil curves of your muscles blurring behind the liquid wall of lust coaxing Denkiâs body. beads of water rolled over your smoothing skinâ the moisture from your shower still sticking to the surface of your body.
âoh? is it not? then whatâs goinâ on, âŠzappy?â the nickname fell from your lips like a satin blanket, dully dressed in the glorious afterglow of pleasure.
the toy inside of Denki was still moving, strongly striking his nerves in mind-blurring fashion. ânnguh! itâitâs because ofâof your vâoice! the video you made!â
you smirked, a dark chuckle leaving you. âso you watch my videos? that makes you a perv, yâknow.â
Denki fumbled, his facade falter alongside the coiling strings of semen erupting from his slit. âunugâha!â his moan was spun on the web of a gasp, snatching his bodyâs actions away from him. âIâ uhg! âŠnâno! thatâs nânot what Iânghm! meant!â he gulped back his shame, sitting up against your wall. âIâ was jâjustâŠâ his eyes traveled everywhere, looking for a plausible explanation as to what he was very obviously doing.
you pushed off the frame of your door, dragging your tongue along the ridge of your teeth. âso what did you meanâŠDenk?ââ
the way the nickname burrowed yourself into his skin make him quiver with anticipation. though he didnât know what to expect. âanything you wanna say?â the question was laced with greedâ almost as if you were teetering on the idea of turning him into a, your slut.
your knee connected with the edge of your bed, your weight dipping the mattress intolerably. the water from your hair dripped down your body, running circles on your torso before making way to your v-line. âIânghm! I was, just⊠just trying toâŠâ his eyes lowered. âuh! uhm, well⊠I guess youâ weâŠ!â
âeyes up here, Denkâ.â
you brought your hand to his chinâ almost in a clichĂ© sense, your eyes locking in a one-sided battle. âso, Denk⊠what were you doing?â
you were hovering over him, your height difference clouding, if not completely obscuring his perspective. your bulge pressed into the cusp of his thighs.
a shallow gasp escaped you, your head dropping to look at him. his legs were shaking slightly, the skin of his body smooth and perfectly poised. âgod, your so beautiful.â
Denki flushed; his eyes darting around articulately. his body was cleansed of its own blood, now replaced and replenished by the torrents of your own; he was bound to you. bound in your spell.
âis this my shirt?â his eyes finally focused, the grey material momentarily filling his vision before you took it from him. âis this where my clothes have been going? on your pervy little curves? helping you masturbate?â
ânâno! I havenât been dâdoing anything, man! Iâve juâjust been low onâNGHM!â Denkiâs hands came up to your shoulders: gripping and scratching along the skin. â[nâname]! IâI just said thatâ ngh! I didnât stâsteal your cloths!â
your fingers intersected themselves in the innermost nerves of Denkiâs body. he reflected the feeling of arousal in his eyesâ the sensation causing the irises of his eyes to gloss over with tears.
âthis isnât about my clothes, Denkââ you groaned, feeling Denkiâs legs press on the head of your cock. âits about you. and what youâre doing in my room. with my shirt over your face, and a fuck machine in your ass.â
you displaced your fingers, rubbing them along his prostate. âso, what exactly are you doing?â
Denki threw his head backâ a sound erupting from his mouth in a dysphoric rage of moans. âmmgh! Iâ I wâwas low onâahgn!â a sharp thrust of your fingers stopped his sentence, his cock twitching with precum.
âstop lying Denkâ you know mom hates that shit.â
your cock throbbed painfully, the towel around your waist falling to your thighsâ your cock rubbing against your step-brotherâs abdomen. âcâmon Denkââ you almost whined, desperation washing over you in arcs of painful crescent moons. âIâm so⊠fuckinâ horny.â
your fingers glistened within himâ a grandeur sound resonating within him. he audibly gasped at it, trying to move away from you but your sudden grip on his thigh altered his movements, making him slide under you instead.
he gulped, finding himself floundering around at the feeling of your cock against his stomach. it aligned with the skin just above his belly button. his movements were spastic, a jumble of jerks and twist sending molten plasma down your shaft.
âDenkâŠâ your words were coldâ rigid with seething but controlled gasp. âif you keep movinâ like that, Iâll cum.â
Denki blushed, a liquid crimson band covering his entirety. his movements momentarily halted, the surges of lust nestling into his stomach, coiling into a warm feeling that tightened with each move of your fingers
however, they left his body in a sickly masochistic way. you brought your fingers to your mouth and slid your tongue along the skin, maintaining a dysphasic tone of eye contact. the look in your eyes heating Denkiâs body to an all time high.
your fingers, now covered in a flowing sea of spit and lube reached for Denkiâs lipsâ breaking the surface of his mouth. his heartbeat was in his throat, yet, he still took your fingers into the depths of his mouth.
you played with his tongue, using your index and middle to balance the pink muscle in a titillating, slightly uncomfortable fashion.
you moved once more, shoving yourself into his throat. he choked and gagged, spitting around your knuckles but made no attempt to stop your brutality.
after a few seconds, you took your fingers away from him, letting him breathe.
âwhat were you doing in my room, Denk?â you asked once more.
âhnah! mngâh! IâI wasnât doinâ anything, maâman!â
you chuckled, moving your hand to your cockâ stroking from base to tip. with your other hand, you wrapped his torso in your forearm, lifting him to your v-line. âtsk, tsk. mom would be disappointed.â your tip grazed his hole, âfirst, you have the shameless idea to masturbate in my room, then you lie about it.â
you pushed inwardâ also grabbing your shirt and shoving it into Denkiâs mouth. he moaned around the fabric, his eyes crossing when you had yourself fully excavated within him. âI guess youâve always needed a little more time to learn thingsâŠâ
your hips fell away from him, dragging your tip down the ridge of his spine. the afterimage of your shaft was still intact; exhibiting through his pelvic muscles. it was filthy. utterly disgraceful to witness. âbut⊠itâs a good thing youâve got me.â
not a second later, his catalyst was filled once more, your cock reaching intolerably deep into his physique. his arms slid down your chestâ leaving scarlet marks on your abdominal walls.
a hiss left your lips, the sound similar to a snake. you grabbed his wrist with one of your hands, using the other to snatch your shirt from his mouth. âhaah! [nâname]! deâdeep! câcock too deepân meâŠ!â
you wrapped his wrist in your shirt, taking the edges of the bindings and crossing them into his drooling lipsâ the knot forming a gag. âmy what?â you mocked, laughter soon filling your white-walls. âtoo deep? you were just using a fuck machine, jerking your dick to the smell of my clothes! now itâs too deep?â
you began thrusting shallowly, moving his thighs to your chest and pulling his legs to fall down your back. a swift motion of your hips shook Denkiâs body, pushing him into his second orgasm.
he tightened around you, a convulsive throbbing in his cock and rapidly clenching hole gave way to the white twine and muffled moans of your step-brother. he thrashed his hands aroundâ vigorously trying to grip onto anything.
you grinned at this, continuously thrusting into him. Denki felt his consciousness leaving him, his eyes falling lidded and heavy.
you, stuttering over the feeling of your own body, groaned profuselyâ your hips stinging with exhaustion. âyouâ mgh! you canât handle my dick? if you wanna tap out, just tell me what you were doing in here.â
Denki mumbled, not knowing how to form correct words. âIânguhm! neâ never anythâng! do thâng!â he consulted his eyes, the orange pupils glass-like and heart-shaped. ânghu! FUGKH! mâman! caâcanât think!â
a skeletal architecture altered into his body, forming a permanent semicircular shapeâ an arch lifted his body off the bed, rubbing your slit into his prostate.
both of your cameâ your cock trembling with painful arcs of melancholy emission staining the onslaught of Denkiâs organs. his body spasmed with crude pleasureâ his eyes rolling into emptiness.
his body went limp in your arms: mouth slack, eyes closed, and breathing shallow.
your body heaved, heavily burned from your orgasm. your cock was still deep within him, your semen creating a barrier between the two of youâ however his warmth was still surrounding you in surreal relief. it begged you to keep going, begged for you to unload your balls and every drop of cum you had into him.
a gulp traveled intermittently across your tongue, cascading into your throat. you casually slipped your finger onto his waistâ gripping the skin in a gentle embrace.
you pushed your pelvis further into him, your tip ramming against the bottom of his enclosure. your head tilted back, eyes closed with plenty more pleasure.
you pulled from him, slamming back against his skin in a single breathless moment. his body rippled through with waves of light. sweat enchanted his body like a giant cloud, puddling on his stomachâ entrancing the skin alongside the pool of his cum.
you again thrusted into himâ this time harsher. you were transported to another world, blissfully unaware of Denkiâs stirring body. he was waking back up, his cock sleek with pre-cum.
his vision was still obscured, the feeling of fabric still plastered over his tongue. he whined, more pre-cum falling from his slit. âmghphâ phuhk muh! [nuhmhe]! chaut câcanât cuhm! nâmore!â
you couldnât hear him. you were completely lost in your own thoughts: the same words repeated throughout the entire time, âfuck him! fuck him until he canât walk! fuck him! fuck him! fuck him fuck him fuckhimfuckhimFUCKHIMFUCKHIM!â
your thoughts mushed together, a singular statement that dug deeper and deeper into your mind. it burned into your brain, forcing your hips to move internally deeper, milking a third orgasm from Denki. he couldnât speak, couldnât move, he was racked with tearsâ crying out in ecstayïżŒ
you were panting heavily, biting down on your lip to keep your sounds of elation. your orgasm was slowly steeping upon you, the feeling setting off a buzzing sensation all over your body.
âfuuhk⊠Denki, Iâm gonnaâ Imma cum.â
Denkiâs legs shook with excitement, another orgasm rumbling through his body. he screamed around your shirt, pressing his hips against yours. spit dripped from his chin, running down his abdomen and onto his maroon shaded tip.
overwhelming coils of heat knotted within you, pushing your hips into an uneven pace
you werenât aiming at anything, just hitting Denkiâs body over and over again. you were chasing after an orgasm that was mere inches away.
sloppy thrust turned to harsh, animalistic tacticsâ erratically fucking Denki into the soft cloth rubbing against your balls. you were going crazy, the heat from your abdomen shooting into your tip, choking you in a panicked rage.
you leaned down to Denki, ripping your shirt from his lips, quickly replacing the cloth with the chapped skin of your lips. you messily kissed along his face, moving sloppily to his neck. âwhoâs your daddy?â
Denki moanedâ the sound hoarse and cracking. âyâ[name]! mâdaddy! mâyer slut!â
the words only continued to edge you, your tip twitching inside him, âsay it againâ fuck⊠Iâm so close to giving you my kidsâŠ!â your shaft throbbed at his mindlessness, the moans bouncing like embers from a raging river of fire. âplease, say it againâŠ! whatâs my name, Denk?â
âdaddy! daâduaddy! mngh!⊠maâcuhm! cuhm nâdaddyâs cock!â again Denki clench around you, his swollen hole screaming at you to keep goingâ keep abusing him until your name was spelled into his organs.
âfuââ you couldnât finish your sentence, a powerful surge of pleasure rushing through every blood cell in your body, energetically jerking your lower body around. like an angry explosion your cum clawed its way through you, pushing out any and everything you had within you, transferring it into Denki.
Denkiâs cum was clearâ thin and falling onto his pecs, dripping like water onto his face. he shivered at the feeling, not having the energy to move or even breathe correctly.
you sighed, head falling painfully to your pillow, the feeling of Denkiâs hair right beside your face annoying the nerve endings of your skin.
you pushed his head away, closing your eyes and drifting into a deep sleep.
â[NAME]! DENKI! WHAT IS GOING ON?! WHAT ARE THE TWO OF YOU DOING?!!â
