Chapter 1: Toji Fushiguro

Chapter Text

you were never some innocent kid when it came to your mom’s shit. you knew exactly how she was into getting high and getting laid. 

specifically, she’s got a thing for meatheads, and she isn’t above paying for any male prostitutes when she’s bored. honestly speaking, that doesn’t even faze you. why? because that kind of fucked up system is just the house you grew up in.

and when you say ‘house’, you mean a father and a mother. and your dad was no better. he was a textbook womanizer who basically died because he couldn’t keep his dick in his pants. but technically, he lived with a deadline; he was ill (has a chronic illness).  and you suppose when you’re living on borrowed time, you spend it where you feel most alive. for him, that was anywhere his dick could lead him.

anyway, you knew it was only a matter of time before your mom found a permanent warm body to replace him (or at least that’s how it looks). 

what you didn’t expect was for her to drag in a homeless, broke ass guy off the street. it piqued your curiosity. you know your mother, she’s not the type to even deal with penniless losers unless they’re packing a massive dick or they’re built like a tank.

turns out, you were right.

yeah. 

toji fushiguro. 

that’s the guy fucking her senseless every night and he’s exactly what you expected: huge, muscular, and has that thick-faced look of a man who knows exactly how much space he takes up in a room.

it had been a few weeks, and you were already being turned into a restless, sleep-deprived loser, and that insomnia had nothing to do with it. for a girl used to buying her way out of any problem and getting every whim catered to, this was a new kind of itch. 

it had become a sick little routine. every night, you found yourself pacing the hallway outside the master’s bedroom. 

they didn’t even try to be quiet anymore.

they were at it again. they were always at it.

the noises were loud enough to echo through the massive hallways. your mother wasn’t even trying to be discreet. she sounded like she was being eaten alive. 

and toji? 

he was fucking shameless. he knew there was a daughter in the house just a few feet away, but he didn’t give a single shit. 

he was a thirty years old squatter with an ego, treating the woman who paid his bills like a dog (well, technically, she’s probably on all fours right now so you might be right about that).

“is that all you’ve got?” your mom gasped. she couldn’t even hide the desperation in her voice anymore. 

“shut up and take it,” toji’s voice came through that made your skin crawl. “stop whining and keep your ass up.”

the sound of a heavy slap rang out, followed by a sharp intake of breath. he was fucking her like he was trying to break the bed frame. he called her names while he was buried inside her. it was filthy, degrading, and utterly hypnotic.

you should be disgusted. in the first place, hearing two older people acting as your mom and dad fucking would be very awkward. well, it IS unquestionably awkward.

and you? you stood there while blushing profusely. 

you must be sick in the head too, aren’t you? 

your skin got itchy and you can’t move your feet to walk away, cause you are literally starting to crave what you’re hearing.

toji was nearly a decade older, but it felt like a century. he had that dead eyed stare that suggested he’d seen everything and wasn’t impressed by any of it: not your family’s wealth and definitely not the unhinged brat (you) listening from the shadows. 

he didn’t walk on eggshells around you; he didn’t even acknowledge the eggshells existed.

it was a full blown obsession now.

like you’d be at your desk trying to study, and then you’d hear that first moan or the smash of the headboard, and you were up, immediately out the door, into the hallway just to listen to toji earn his keep.

it was inevitable. his performance in bed must have been a religious experience for your mother, because she didn’t just keep him as a pet, she literally decided to remarry. 

now, toji was a permanent distraction in your own house: sat across from you at breakfast, lunch, and dinner, eating the food your mom’s money bought. it was a fucking fever dream, watching him play house while you sat there with itchy skin.

you knew your obsession was a sickness. fantasizing about the man who was technically becoming your stepfather was gross, even by your standards. 

tonight, your mother was away on a business trip. you did your usual walk down the hallway, expecting silence, but then you heard a single, low groan. not your mother’s desperate whimpers, but a deep sound that could only belong to him.

the door was half open and when you peaked through the gap, the sight made your breath hitch in your throat. 

toji was sprawled across the massive bed. he was alone, but he wasn’t idle.

his hand was buried in his sweatpants, moving up and down slowly, but still made the bed frame creak. i mean, that view itself was surprising, but…

it was his other hand that made your heart stop. he was holding a pair of lace underwear.

and that underwear:

is unmistakably yours.

he had his face buried in the fabric, inhaling deeply while his eyes closed in a sort of dark, twisted concentration. he wasn’t thinking about your mother while he was masturbating. he was sniffing your scent out of it while he worked himself over.

the man who was supposed to be your new father figure, was currently defiling your clothes in the dark. and as you watched him, you realized the obsession wasn’t just one-sided anymore.

your mother was still miles away the next morning, meaning you’re still left alone with the man who had spent his night inhaling your scent and masturbating off it. 

you walked into the kitchen and found toji already there.

he was leaned against the marble counter with a cup of coffee in his hand. he didn’t even look up when you entered, just stared out the window with that same bored expression.

“you’re up early,” he remarked. he looked at you then, his eyes dragging slowly from your feet up to your face.

“couldn’t sleep,” you answered, steadying your voice despite the adrenaline. 

you moved toward the fridge, purposely brushing past him. the scent of him hit you hard. “it was too quiet last night. i’m used to a lot more... noise coming from down the hall.”

toji let out a short, dry laugh. he set his coffee down and watched you reach for the juice. “missing the show? i thought a pampered brat like you would appreciate the peace and quiet.”

you turned to face him, leaning back against the counter, crossing your arms. you gave him a knowing look. “not really. i actually find myself getting pretty observant when things get quiet. for example, i noticed something was missing from my laundry this morning.”

toji tilted his head, making his dark hair fall into his eyes. “is that so? what’d you lose? a diamond earring? a gold spoon?”

“underwear,” you stared at him, trying to match the intensity of his pair of dead eyes. “an expensive one. the kind of thing that doesn’t just disappear unless someone went looking for it.”

toji didn’t even flinch. instead, a predatory smirk pulled at the corner of his mouth. it looked like he was caught, okay, but does he care? no. 

he took a step closer, invading your personal space until you could only look up just to meet his gaze.

“maybe you just misplaced it,” he said and leaned down, his face is now inches from yours, feeling his warm breath against your cheek. “or maybe there’s a thief in the house. you should probably be more careful where you leave your things lying around. someone might get the wrong idea about how much you want to be noticed.”

he didn’t back away. he just stood there, waiting to see if you’d break first.

of course you didn’t flinch. why would you? 

instead, you leaned into his space, reaching out to trace the edge of the marble counter right next to his hip and looked up at him.

“you’re awfully bold for a guy who’s one phone call away from being back on the street,” you whispered teasingly. “i wonder how my mother would react if she knew the man she’s so obsessed with spent his night alone in her bed, fantasizing about her daughter. especially one nearly a decade younger than him. it’s a bit pathetic, don’t you think? getting off on my laundry?”

you expected him to look away or pull back, but toji just stayed there, as solid as a stone wall. 

“pathetic?” he repeated and let out a dry chuckle. “maybe. but i’m not the only one with a habit, am i?”

he moved closer, pinning you against the counter without even touching you.

“you talk about your mother like you’re worried about her feelings,” he raised a brow at you, as if mocking your very existence. “but let’s be real. how would she react if she knew her precious, privileged daughter spends her nights listening to me fuck the life out of her? how would she feel knowing you’ve been imagining it was you in that bed?”

his eyes dropped to your lips, then back up to yours.

“we’d both be fucked,” he concluded, smirk widening. “you’re just as sick as i am, kid. maybe sicker.”

he reached out, his long and thick fingers ghosting just an inch away from your jawline, refusing to give you the satisfaction of actual contact.

“so, what now? you gonna tell her? or are you gonna go back upstairs and think about what i was doing with that panty?”

the smug look on his face was infuriating. you hated losing, especially to a guy who was supposed to be nothing more than a glorified pet in your mother's house. 

that arrogant smirk he’s wearing made you want to slap him and scream at him, but at the same time, the way he read you so easily made you wet your own pajamas. 

you didn’t say another word, just grabbed your drink and stormed past him, and the sound of his chuckle followed you all the way back up the stairs.

it was a few hours later when your phone buzzed on the nightstand. 

it was your mother.

“hey, honey,” she said. judging by the sounds of her background, she was probably at the airport or in the back of a car. “just checking in. everything okay at the house?”

“fine,” you replied flatly. “boring as usual.”

there was a long pause on the other end, a moment where she was choosing her words carefully. your mother wasn’t an idiot.

she hadn’t survived your father’s bullshit without developing a sixth sense. she’s just as crazy as you, if you remember correctly.

“i know how... intense things can feel at home right now,” she started. “toji is... he’s a lot for a man. i know you’re used to getting your way, but don’t let your curiosity get the better of you while i’m gone.”

you sat up, your grip tightening on the phone. “what is that supposed to mean?”

“it means,” she said, “that i brought him in because he fits into my life. he isn’t a toy for you to poke at because you’re bored or restless. stay in your room, and let him be. i don’t want to come home and find out you’ve been... making things complicated.”

“i’m not a child, mom,” you snapped.

“then stop acting like one. i’ll be home tomorrow. love you.”

she hung up, leaving the dial tone ringing in your ear. 

you tossed the phone onto the bed. of course, she was threatened. she knew you were a predator just like her, and she was terrified you’d try to take what was hers.

but being told ‘no’ had always been the quickest way to make you want something even more.

the house went back to normal at midnight. 

the silence was shattered the second your mother walked through the door, replaced by her familiar muffled screams. 

meanwhile you sat in your room, staring at your textbooks, hating him. you hated his stamina and that if he were just some average guy, she’d have been bored of him by now. but he was big, and he was relentless, and it kept her hooked like an addict.

it was a cycle you couldn’t break, and it was wearing you down.

a few days later, you were standing on the curb outside the university, looking at your phone with a scowl. your car was still in the shop, in probation for a reckless driving incident you didn’t feel like apologizing for and both family drivers were occupied. 

your mom had sent a text: toji is coming to get you. don’t make a scene.

“seriously? you’re still waiting for a ride?”

you looked up to see a guy from your business law class. he was wealthy, attractive in a conventional way, and had been chasing you for months. 

he wanted to fuck you, and he wasn’t shy about it, but every time he looked at you, you just compared him to the man in your house. who’s far bigger in every aspect.

“my ride’s on the way,” you said, your voice dripping with your usual bored arrogance.

“i could just take you,” he stepped closer, reaching out his hand to brush against your arm. “we could grab a drink. my parents are out of town, and i’ve got that vintage wine you liked.”

he was laying it on thick, leaning in to whisper something in your ear, when a rumbled engine cut through. then a black suv pulled up.

the driver’s side window rolled down slowly, revealing toji. he looked even more out of place here than he did at your dinner table. 

he was dressed in a tight black shirt that showed off every muscle on his upper body. his dark eyes flickered from you to the guy beside you, who still had his hand on your arm.

toji didn’t get out of the car. he just leaned his elbow on the window frame, looking at the two of you.

“you done?” toji’s voice was a low. “your mother wants you home. she didn’t say anything about waiting around while you played house with this kid.”

the boy frowned, trying to keep his composure. “who’s this? your bodyguard?”

toji let out a dry laugh and looked the boy up and down.

"i’m her dad, kid,” toji said, his eyes finally locking onto yours knowingly. “get in the car. now.”

it was the same tone he used when he told your mother to shut up. the guy you’re with looked offended, but you didn’t care about him at all.

the traffic that followed was a nightmare. inside the suv, the air conditioning was the only sound you can hear, but the chills it’s supposed to give didn’t do anything to cool the suffocating tension between you. 

toji used one hand lazily on the steering wheel, looking bored out of his mind, as if he hadn’t just humiliated a guy half his age in front of the entire campus.

you shifted in the leather seat, crossing and uncrossing your legs. 

the sight of him asserting dominance back there had done something to you and the fact that he was acting like nothing happened was driving you insane.

“you’ve got a lot of nerve,” you finally snapped. “acting like a protective father back there. you really care that much about another guy trying to get under my panties? that’s pathetic, coming from the man who spends his nights sniffing them in my mother’s bed.”

toji didn’t even turn his head. he just tapped on the wheel. “i don’t care who you spend your time with. i just don’t like waiting. you were dragging your feet, and i have better things to do than watch some trust-fund kid beg for a taste.”

“is that it?” you leaned closer to him. “because it looked a lot like you were marking territory.”

you waited for a reaction, but he just let out a dry, irritating laugh.

“you think pretty highly of yourself, don’t you?” he mockingly said.

“i know what i saw,” you countered, your hand sliding down your own thigh. “and if you’re so desperate to get close to my underwear, why settle for the ones in the laundry? i’m wearing a pair right now. and because of that little ‘jealousy’ display back there, they’re already soaked. you want to smell the real thing, toji? or are you too busy playing house with my mom?”

the silence that followed was deafening. you thought you’d won, thought you’d finally pushed him to a point where he’d be flustered.

but toji wasn’t just some guy. 

he finally turned his head, it made your heart skip a beat. 

“you’re a real brat, you know that?” he was smirking without humor now. he looked out at the traffic, then back at you. he shifted in his seat. “you want to talk about what’s going on in those panties? fine. but i’m not interested in just smelling them.”

he reached over. then his large hand gripped the back of your neck and pulled you toward him until you were inches from his face.

“if you’re so wet and so eager to make this complicated, then earn it,” he growled. “the traffic isn’t moving for at least twenty minutes. get down there and blow me. let’s see if that mouth of yours is as good at taking orders as it is at talking shit.”

you weren’t about to back down. 

your heart was hammering against your ribs, but your pride was far too loud to let him win this round. you stared him right in those dark, mocking eyes. 

“is that it?” you whispered. “you want me to work for it? how about you do your job first? if you want to get off, take them off me yourself. show me how much you actually want what’s inside them.”

toji’s expression shifted then. he didn’t say a word, though the smugness is still there. he just reached over, his massive hand disappearing under the hem of your skirt.

the way he did it like an expert made you gasp. 

his fingers hooked into the waistband of your lace panties and dragged them down your thighs, then he tossed them onto the dashboard after.

he didn’t pull away. instead, he pressed his palm flat against your soaking pussy now. his fingers were calloused and big, and he began a slow massage; grinding the heel of his hand into your clit while he watched your eyes blown wide with shock

“ah-uhmm,” you moaned involuntarily.

“you’re fucking drowning, aren’t you?” he grunted, feeling the wetness of your precum coating his fingers.

he withdrew his hand, showing his glistening and dripping fingers. 

he didn’t waste a drop. with his other hand, he reached into his pants and freed his dick. and your jaw dropped. it was already thick and standing proud, throbbing with vein-mapped weight. 

you watched, mesmerized, as he took your precum from his fingers and smeared it slowly up the length of his own dick, glazing the head until it shone in the dim light of the car.

then, he reached for the lace panties on the dash. he stuffed them into his mouth, biting down on the fabric, as he inhaled your scent directly while he worked. his eyes stayed locked on yours, as he reached back down and buried a thick finger deep into your pussy.

he pumped three his fingers inside you, forcing more of your precum to spill out so he could use it to keep wetting himself. he was being deliberate, showing you exactly how much of a degenerate he was. he wasn’t just taking what he wanted; he was using your own body to prep himself, all while biting down on your underwear like an animal.

he leaned back, and gestured with a tilt of his head toward his dripping, rock-hard dick. even with the fabric in his mouth, the command was clear.

the challenge was over. you didn’t need another word from him and the sight of your own fluid being smeared over his thick, throbbing dick was enough to break whatever restraint you had left. 

you scrambled over the center console, you no longer cared if your skirt was riding up to your hips as you dropped to your knees on your seat and the other leg was supporting your whole weight in your own footwell.

as soon as you took him into your mouth, you realized exactly why your mother was so addicted. the head of his dick was broad, stretching your lips as you struggled to take the full width of him. you swirled your tongue around the rim, tasting salty and your own precum, before sinking your throat onto him.

“fuck,” toji groaned. he didn’t play nice. instead, he reached down and fisted his hand into your hair, locking his fingers near the roots as he pulled your head back to look at you. “look at you. the little princess on her knees. you’ve been wanting this dick since the first night you stood outside that door, haven’t you?”

he didn’t wait for an answer. 

he began to shove his hips forward, meeting your mouth with a brutal pace. his other left hand didn’t stay still. he reached down between your legs, finding your pussy again and buried two thick fingers deep inside you, hooking them upward to find the spot that made your toes curl.

the car was filled with the sound of his moans and the wet slaps of your mouth against his groin. 

toji was shameless, tilting his head back against the headrest, tightening his jaw as he watched the traffic through the windshield while his step-daughter sucked him off.

“suck it harder,” he growled, as he tightened his grip on your hair, forcing you to take him deeper, hitting the back of your throat. “use that tongue. i want to feel every bit of that expensive education you’re getting. show me how much of a slut you can be when your mom isn’t looking.”

his fingers inside you were relentless, finger-fucking you with speed that matched the aggressive thrusts of his cock in your mouth. he was stretching you out, grinding his thumb hard against your clit, making you shake and wet yourself more.

your saliva was even dripping down his balls as you tried to keep up his animalistic pace.

“yeah, just like that,” he hissed as a guttural moan escaped him when he felt your throat clench around him. “fucking brat. you’re even tighter than she is.”

he was beginning to lose that smug composure from ragged stabs as you worked him. he was close, and he wasn’t planning on pulling out.

the car was so full of the smell of sex, even the windows fogged over as toji’s fingers worked you. 

you were losing your mind, your tongue was dancing around the head of his dick while his three fingers hammered in and out of your pussy. he was hitting that specific spot over and over that had you gasping around him while your eyes rolled back.

“fuck, you’re so sensitive,” his voice was kind of breaking as he felt your internal muscles start to squeeze his fingers. “you’re gonna go, aren’t you? do it, brat. give it all to me.”

he increased the pace, making his thumb crush your clit while his fingers were buried deep, and that was it. 

you buckled, as a violent wave of pleasure crashed over you as you squirted.

a hot spray of your juices hit his hand and soaking into the leather seat. you were shaking, letting out a muffled moan vibrating against his dick as your body gave up everything.

toji didn’t stop. he let out a moan of his own too while he watched you come. he withdrew his dripping fingers from your pussy, with your cream and the remnants of your squirt. 

and without a second thought, he brought his hand to his mouth, licking his fingers clean, tasting you while he watched you tremble. 

the sight of him eating you out of his own palm while his dick was still buried in your throat was the final straw. he was right there.

“don’t you dare move,” he growled, slamming his hand back into your hair to lock your head in place.

he didn’t let you pull away to catch your breath. instead, he surged forward, bucking his hips more. he let out a long, loud groan that echoed off the glass as he finally came, his dick was throbbing violently in your mouth. 

he pumped load after load of hot cum directly into the back of your throat, forcing you to take every bit of him while he stared down shamelessly. 

he stayed there for a long moment, pulsing inside your mouth as the last of his cum spilled over your tongue. 

when he finally pulled out, his dick was glistening. he leaned back against the seat, completely unfazed by the fact that the traffic had finally started to move.

he wiped a stray drop of spit from his lip as he looked at you, messy and unhinged on your seat.

toji didn’t offer a hand to help you up. instead, he just watched you scramble back into the passenger seat, while your face was flushed and your lips were swollen. he reached over, his thumb swiping a thick smear of his own cum from the corner of your mouth, and then he licked it off his skin right in front of you.

“clean yourself up,” he muttered as he shifted the car into gear. “you look like a mess, and i’m not the one explaining to your mother why you’ve got my cum all over your face.”
