Izuku x Fuyumi is one of my favorite pairings, there's so much potential for the Princess x Knight in Shining Armor dynamic with their relationship, so I had to write this for them! Being the responsible, eldest child in a stressful family environment can be a very emotionally draining experience, so I definitely wanted to portray what the Todoroki family situation has done to Fuyumi and give her the respect she deserves by allowing Izuku to help her focus on her own personal life for a change! And there are some elements of their relationship being a huge middle finger to the men in her family because I think the cucking vibe is hot.


The cold never bothered Fuyumi, but she'd be lying if she said she wasn't getting tired of being so used to it. Another night, another cold and empty bed that she was coming home to as she sighed and let herself in. Her father and brother were both sitting in the kitchen, which was a rare sight—usually Natsuo avoided Enji, even if they were slowly getting on better terms.

"So? How was your date?" Endeavor dramatically set whatever paper he'd been reading down.

Fuyumi tried to be patient with her dad, but tonight was not her night as she blew at one of her bangs and hung up her jacket. "I got dumped, obviously."

"What?!" Both Natsuo and Enji jumped to their feet at the same time. "What do you mean?"

She resisted the urge to roll her eyes, hands on her hips as she fixed the two men with a hard stare. "If my boyfriend had a dad that was so overbearing and overprotective that it made any relationship feel like a ticking time bomb, I'd get out, too!"

The surprised look on her dad's face only made her sigh more heavily. "Dad, when I brought him over last week, you spent hours lecturing him and threatening to burn his car if he ever 'stepped out of line'. I don't blame him for leaving! This isn't the first time it's happened, either! I'm 25, and I'm certain the reason why I've never kept a boyfriend longer than a month is because you're always breathing down their necks and chasing them away!"

Enji looked like a deer in the headlights. "I…I'm sorry! Fuyumi, I'm sorry! I don't mean to make things hard for you…I just want to make sure you find the right person. You're my only daughter. I don't want you to end up with a guy that'll be…like me."

Fuyumi just crossed her arms, raising an eyebrow at her dad's attempt at an emotional speech. "Listen…it's not that I don't appreciate that you want to be involved in my life, but I just think you've taken it a step too far."

Of course, somehow, even though she'd been the one who just got dumped because of her intimidating father, she had to be the one now walking over to him and comforting her dad. Such was the life of the eldest daughter.

As Enji sat down, that brought her attention to Natsuo who was just standing awkwardly off to the side. "And? Did you have something you needed to say to me?"

He rubbed the back of his head. "Well, we said we were gonna prepare some sweets to bring to UA for Shouto's birthday party tomorrow, remember? So I was waiting up for you."

She pinched the bridge of her nose, one hand still on her dad's shoulder. "You could've started without me, you know, instead of waiting for me to come do it all."

"Oh, right. Sorry, sis."

Fuyumi walked past him with a sigh, gathering all the cooking ingredients since Natsuo hadn't even bothered to do that much. "Honestly, you've become way too used to having me around the house, Natsu…what's going to happen when I get married and leave the house? Hm? What then? I won't always be around."

"Married? That'd require you to keep a boyfriend for longer than a month." Natsuo blushed and shrunk back when she whipped around to glare at him. "S-sorry! That came out wrong…"

She huffed, more annoyed tonight than she had been in a long time. "You're lucky we're doing this for Shouto, otherwise I'd leave you to do it by yourself…"

He remained silent for the rest of the night as they baked for Shouto's birthday tomorrow. Enji excused himself to his room—as if he deserved to throw a pity party tonight when he was the one messing up Fuyumi's romantic life! Not that she said anything quite that harsh to his face, but she couldn't help but think it.

Finally, after an hour in the kitchen, Fuyumi collapsed in her bed for the night, squeezing the blanket around her and staring up at the ceiling.

25 years old, and completely single…she didn't want to put all of the blame on her dad, even if she did feel like he was too strict with her dating life. So if the blame wasn't completely his fault…then was it something about her? Was she doing something wrong? Maybe she was too focused on her family life? She did spend a lot of time taking care of her family, after all, even though she rarely felt appreciated by her brothers…she didn't see Shouto often, so that was understandable, but Natsuo could show his gratitude more often!

With a tired sigh, she took off her glasses and shut her eyes, dreaming of the day she'd finally find the right guy. A guy who would just…treat her right for once and not be scared off by her family. She wasn't getting any younger, after all.


The next evening, once Natsuo was done with his weekend college classes, they began packing up the food from last night to take to UA.

"I'll come with you!" Enji insisted, but they both immediately shut him down.

"You'll just cause a scene. Come on, sis." Natsuo hoisted up a separate bag that he'd brought home. Fuyumi quickly checked it and gasped.

"Alcohol? Natsu, they're under the drinking age!"

Natsuo shrugged. "They're in their third year, it's fine! I mean, when I was 18, I asked my older friends to buy alcohol for me all the time! So now, I've gotta be the cool older brother who gets this stuff for Shouto!"

Fuyumi grumbled. "If you get in trouble, don't expect me to bail you out."

"If you're going to be drinking, then make sure you drink responsibly," Enji called out as they left the house. "And, uh, Fuyumi…I know you criticized me for this last night, but as your father, I still must tell you not to bring home any boys from the party."

Fuyumi nearly lost it as some frost even spread across her neck—her version of blowing steam out of her ears. "We're celebrating with Shouto's highschool friends—I'm pretty sure you don't have to worry about that! Ugh…"

Natsuo raised an eyebrow. "Are you on your period or something? 'Cause lately you've been way more, uh…never mind." He zipped his mouth shut as she glared at him.

Finally they arrived at the class 3A dorms, where everyone urged them inside so they could gawk at Fuyumi's cooking.

"I didn't even know you two would be here." Shouto managed a rare smile as both of his siblings hugged him. "Dad isn't gonna show up, is he?"

Fuyumi shook her head. "He almost did, but we talked him out of it."

"What is this?!" Iida shouted, hands on his head as Natsuo revealed the alcohol.

"Come on, man! This is the life of the party!"

The two of them proceeded to argue, which just had Fuyumi shaking her head and walking to the living room. Natsuo was seriously such a child, still…

Fuyumi was definitely not a child, though. She was the oldest here and the odd one out, so she obviously wasn't here to party hard or anything. This was the younger kids' time to shine, so she sat on one of the living room couches and pulled up an eBook on her phone to read. She'd recently been enamored with the romance genre for obvious reasons.

The party only got louder and louder over time, but she was used to working with kids and focusing on her book in the middle of chaos. Only when the couch dipped as someone sat with her did she look up from her phone.

"Hey! We haven't gotten to talk, yet!" A familiar green-haired smile was only a few inches away from her face, making her jump back a bit.

"O-oh, Midoriya! It's been a while."

"Yeah, but I'm glad to see you again. Your cooking is as good as always!" He praised her. "Sometimes I wish Todoroki would invite me to his house more often just so I could taste more of your cooking! And, um, to see you, too, of course…"

She laughed lightly. "Well, I'd be careful, if I were you. My dad will yell at any boy that enters our house nowadays."

Midoriya raised an eyebrow. "What do you mean?"

"Oh, I didn't mean to bring up my family drama out of nowhere! Sorry, it's just been all that's on my mind lately, I guess. But it's nothing, really!"

His eyes softened, and he scooted closer until she could feel his body heat. "Hey, it's alright! I'm used to it by now, anyways. Not that that's a bad thing! I just mean…I've been pretty involved in your guys' stuff, so, you know…what I'm trying to say is, I care about your problems."

It was such a simple act of kindness, and people always said not to mistake kindness for flirting, but Fuyumi still couldn't help but blush. She blamed it on her dating issues and her issues with her dad—all of it left her vulnerable and yearning for male attention lately. Maybe that was why she finally gave in and spilled her heart out to the first cute boy who expressed concern for her.

"I've just been having some issues with dating lately, mostly because of my dad. You can probably tell, but he's a little intense…and he totally flips out at any boys that I bring home! Ugh, I know this sounds like the issues of a teenager, yet here I am, a 25 year old woman whining about how daddy chases away all my boyfriends. I know how pitiful I sound right now…" She sighed and took her glasses off to bury her face in one of her hands, embarrassed and frustrated at this whole predicament.

"Hm…" Izuku listened intently, tapping a finger on his knee before offering her a sympathetic smile. "I see. I don't think you're pitiful at all! The way I see it, Endeavor is probably just overcompensating for your past issues, right? I think once you find the right guy who can get along with him…or the right guy who isn't scared of him…then I'm sure things will work out for you."

She sighed again. "I don't know, Midoriya. I'm getting a little old for dating, don't you think?"

"What?!" He shot up to his feet. "No way! You're only 25! Come on, don't talk about yourself like that." He leaned down to pat her shoulder. "You know what I think? You should try and forget your problems for tonight and just have fun. That's what partying is for, right?"

She shook her head. "I don't know. It feels a little awkward partying with people 7 years younger than me…" She muttered, but when she looked up and met Midoriya's sparkling green eyes, full of encouragement, she couldn't help but bend to his will. "But…I guess as long as I'm here, I might as well join in for a bit. It is my little brother's birthday, after all."

He grinned and grabbed her hand to help her stand up for no apparent reason. "That's the spirit! Everyone's been wanting to talk to you, more, anyways, since you're so pretty!"

She blushed some more and let him lead her across the room, glancing down at their linked hands. Was it just her, or had Midoriya gotten a lot bolder and more confident since the last time they spoke?

They wound up in the kitchen, where Mina was passing drinks off to Momo and Jirou. When she spotted Fuyumi and Midoriya walking in together, she grinned and grabbed two cups for them. "Hey, I thought you might've gone home already, Fuyumi! Hanging around Izuku, huh? Watch yourself—he may have the smile of an angel, but Izuku here is our resident heart stealer. There's not a girl in UA that hasn't heard the rumors of Izuku's bedroom being a stairway to heaven."

Izuku blushed and turned to Fuyumi. "Don't listen to her! Aw man, Mina must already be super drunk…"

Fuyumi wasn't sure what to make of the whole exchange as she accepted a drink from Mina, taking a few sips alongside Midoriya before following him back to the living room, eyes burning into the back of his head. Could he really be such a heartthrob at the school? He didn't really give that vibe, but he was definitely attractive enough for it. Just objectively speaking, or whatever. Not that it was any of her business what Midoriya was like around his classmates. He was just one of her little brother's close friends that she happened to see more often than others—an extremely cute, hot, and charming one, who also tended to express interest and concern at her problems…

She had to physically shake her thoughts away from a rabbit hole of weird fantasies as she and Izuku sat down with a bunch of the class all grouped together in the living room. They all sat in a large circle, and in the middle of it was a table, where Shouto sat with Bakugou across from him.

"Go, Shouto! Show me what a man you've become!" Natsuo cheered from right over Shouto's shoulder, pumping his fist in the air as Shouto gritted his teeth, stuck in an arm wrestling battle against Bakugou.

"Dammit, half-and-half, your quirk doesn't even require biceps…!" Bakugou growled, sweat dripping down his chin and onto the table as the two boys were locked in a stalemate.

For a whole minute, their arms inched back and forth ever so slightly, neither of them breaking concentration for a second even with Natsuo's obnoxiously loud cheering. Then, finally, Shouto slowly began pushing Bakugou down, down, down…SLAM!

"Shit!" Shouto cursed, rubbing his arm and leaning back, yet grinning in triumph as Bakugou stood up and kicked the ground.

"Fuck! That wasn't a fair fight! You only won because my palms were sweaty!" Bakugou snapped.

"You should be used to that, though, bro!" Kirishima called out.

Bakugou grumbled and walked back to him in the crowd, smacking his head a bit as Kirishima just chuckled.

"Alright, looks like the birthday boy is still our undefeated arm wrestling champion!" Natsuo grinned, taking another large gulp from his cup.

"Oh dear, he's definitely drunk already…" Fuyumi averted her eyes as Natsuo hyped up their little brother as if this was some sort of arm wrestling tournament. Was this what highschoolers did at parties nowadays?

"So, no other challengers?" Natsuo challenged.

"I'll go next!" Midoriya stood up, drawing Fuyumi's attention back to the center as he walked towards her brothers.

"What? Deku?" Bakugou whirled around. "There's no way Deku can win if I lost!"

In his quick whirl, Bakugou accidentally knocked his hand against Midoriya's cup of alcohol, spilling it all over his chest and garnering a collective "oooh"ing from their classmates.

Midoriya just glanced down at his chest and his empty cup before he smiled at Bakugou. "Don't worry about it, Kacchan."

"I wasn't apologizing!"

He ignored him and instead set his cup on the table before pulling his shirt up and off of his head, and holy ripped. Fuyumi nearly spat out her drink at the sight of Midoriya's rippling muscles. His broad shoulders were thick with muscle, his biceps looked like they'd bulge out of the skin of his arms, his sides were perfectly toned to his eight-pack muscles…he was literally the dreamboat dorito-bodied hunk plucked straight out of any of Fuyumi's favorite romance movies, and the craziest part was that his shirt had somehow hidden all of that.

I wonder what his pants are hiding? She wasn't strong enough to resist that thought as her eyes glued themselves to Midoriya's body and refused to look away.

"Oh, yeah, now we're talking!" Uraraka shouted as some of the girls whistled in delight, making Midoriya laugh as he took his seat across from Shouto.

"Damn, Midoriya, I never would've guessed you were built like a Greek god. You don't look like the type at all," Natsuo observed.

Midoriya and Shouto grabbed hands, and the arm wrestling began.

Unlike the match between Shouto and Bakugou, Midoriya immediately began to take the advantage, overpowering Shouto and pushing his hand closer and closer to the table. He kept a relaxed smile the whole time while Shouto clenched his teeth.

"I know you're generally considered the physically strongest in the school, Midoriya, but…that's only with your quirk…!" Shouto insisted.

Midoriya flexed his bicep even more, making both his arm and Fuyumi's eyes pop out. "I wouldn't be so sure about that."

Fuyumi found herself at a crossroads—did she root for her little brother, who she would always want to see succeed, or did she root for his friend, who was making her heart and stomach do weird front flips and backflips just from the sight of his ripped, shirtless body and veiny bicep and confident smile?

The truth was, she already knew who she was rooting for, but she didn't want to admit that to herself.

"Try tightening your grip. Here, I'll give you a chance to readjust," Midoriya suggested, reducing his strength and letting both their hands come back to the neutral middleground.

Shouto gritted his teeth. "I really don't need arm wrestling tips from you right now…"

Midoriya's eyes softened, but it was in a teasing way rather than a concerned way. "What's wrong, worried that I'm just giving you the win like I did at our first year sport's festival fight?"

Shouto's right scar began emitting steam as his eyes widened and strained. Midoriya shut his eyes with a smile and slammed Shouto's hand down.

"Victory is Midoriya's!" Natsuo called out, grabbing Midoriya's arm and lifting it in the air. It was way too dramatic for a highschool birthday party, and yet Fuyumi found herself clapping along with the rest of their classmates, eyes never leaving Midoriya for a second…not even when his eyes met hers.

She blushed as he winked directly at her, finally managing to look down at her feet, drowning out the cheers all around her to try and steady her heart. Just what was up with her today? Sure, she was having a crisis because she desperately wanted a boyfriend that she could actually keep long-term, but this was Shouto's friend!

Meanwhile, Midoriya lightly shook Shouto's shoulder. "Hey, I was just riling you up for the arm wrestling, you know that, right? I didn't mean anything I said."

Shouto massaged his arm with a sigh before returning Midoriya's smile. "I know. You've always had a habit of getting crass and vulgar once your adrenaline gets going, Midoriya."

He rubbed the back of his head with a nervous laugh. "Ah, yeah…I guess that sorta thing happens when you spend your childhood growing up with Kacchan."

Everyone laughed at that—with the exception of Bakugou who shouted in annoyance.

"Alright, alright, enough! Move aside, little bro, and let big bro get revenge for you!" Natsuo insisted, taking Shouto's place across from Midoriya.

"Natsuo, really?" Fuyumi chimed in, standing up and crossing her arms. "Trying to flex your ego to a bunch of kids?"

That comment made Midoriya narrow his eyes, biting his lower lip before looking Natsuo dead on. "Let's go."

Natsuo grinned, and the arm wrestle began. This time, Midoriya seemed less playful as he held Natsuo's hand with an iron grip and slammed it down—Natsuo only barely managed to keep his wrist off of the table with a strained face.

"Holy shit, you're strong!"

Midoriya didn't respond, instead glancing to the side at Fuyumi for some reason. She didn't understand why he fixed his gaze at her or why he suddenly seemed more serious, but it made her entire body flush with heat.

Finally, he pushed Natsuo's arm all the way down. "I've got the other hand if you still want more."

Natsuo was breathing heavily, groaning and massaging his arm. "No thanks, man. Damn, you're crazy. I hit my university's gym every weekday, but you're on another level!"

Finally, Midoriya's smile returned. "You were very strong for someone who isn't in hero training." He then turned back to Fuyumi. "What'd you think? Proud of your brother?"

She was more proud of Midoriya, if anything, but she couldn't exactly admit that out loud as she blushed. The whole atmosphere had gotten strangely tense, and she couldn't even tell exactly why that was. All she knew was that she had watched Midoriya overpower both of her brothers, and for some reason, she'd enjoyed it.

"Honestly, with that arm of yours, I bet you could even go toe-to-toe with my dad!" Natsuo hyped him up, lightly punching his shoulder as Midoriya laughed lightly.

"I don't know, your dad's a pretty beefy guy. What do you think, Fuyumi?"

The images suddenly corrupted her brain—the thought of Midoriya standing up to her dad in an arm wrestling challenge for some dumb reason while she stood off to the side and watched left her extremely flustered. She could see it now—Midoriya overpowering her overbearing father and then scooping her up in those strong arms and carrying her off, with her dad finally unable to say anything about the guy she was with…

Even after the armwrestling crowd split off to their own mini-groups, the fantasy had taken shape inside of Fuyumi and wouldn't leave. At this point, she couldn't deny it to herself anymore—she was definitely into Midoriya Izuku, and that thought both terrified and excited her. That was her little brother's best friend! Surely these feelings crossed some sort of sibling code, right? And yet that thought only made her feel even hotter inside. Maybe all of those spicy forbidden romance novels were getting to her…

"Hey! Wandered off by yourself again?" Midoriya found her on a lone sofa again and sat beside her.

She stiffened immediately, clutching her drink closer to her chest. He was still shirtless, after all, meaning it was dangerous to even look at him. "Yeah, the armwrestling got…surprisingly intense."

He chuckled. "Well I didn't want to lose to either of your brothers. Not in front of you."

That comment finally got her to look up at him, a blush rising to her face as she cleared her throat. "So…do you have a girlfriend? I can't imagine you being single."

"I could say the same for you."

Her heart jumped into her throat. He was charming and witty, but that must've been the most flirty thing he'd said all day as he glanced up at the ceiling.

"I dated for a little bit during second year, but it just wasn't what I was looking for."

She cleared her throat. "And…what is it that you're looking for?"

He turned to look into her eyes, and they stared at each other long and hard, silent and thoughtful and lost in each other's gaze. Izuku scooted ever-so-slightly closer, and she gripped her cup tighter. As if taking that as permission, he scooted even closer.

Finally, with her heart hammering in her chest, Fuyumi also leaned towards him, entranced by the glint of desire in his gorgeous green eyes, counting the freckles on his face, tracing his lips with her eyes and hopefully her tongue next…

Suddenly, before their lips could meet, he rested his hands on her shoulders, steadying her body and leaning both of them back. "Why don't we head up to my room?"

You're drunk, Fuyumi, her brain told her. You're drunk off of half a cup of alcohol, and if you follow this boy up to his room, that's proof of it.

"Yeah…okay," she agreed.

Midoriya grinned and held her hand once again, leading her upstairs to the bedrooms. She'd been in this situation too many times to count, now—following a boy to his bedroom, throwing herself at a boyfriend too quickly because she was admittedly a little desperate…but never before had her heart pounded this intensely for a boy. It was like Midoriya was reminding her what her first crush was like.

He opened the door to his room for her, and she briefly remembered Mina's words. There's not a girl in UA that hasn't heard the rumors of Izuku's bedroom being a stairway to heaven.

She wasn't sure what she'd been expecting from a 'stairway to heaven', but it certainly hadn't been…this. A room covered in All Might posters and All Might merch from floor to ceiling.

"Oh, Midoriya…" She couldn't contain her laugh as he turned on his bedside lamp before shutting the door, giving the room a dim lighting. He was doing the most with what he had to make a romantic atmosphere out of an All Might covered room.

"Sorry if it's a little nerdy." He rubbed the back of his head, but she just smiled and sat on his bed.

"I think it's sweet that you're always authentic about who you are."

Midoriya sat next to Fuyumi on the bed, making her breath catch in her throat. His eyes were so intense, too, as they stared into hers. "I've always been more of an All Might fan than an Endeavor one, and don't get me wrong, I respect Endeavor a ton! I appreciate everything he's taught me. But I won't let him intimidate me, either."

The implications were obvious as Fuyumi stared down at her hands in her lap. She knew what he wanted, and she knew what she wanted, and she'd already followed him into his bedroom and they were already side by side on his bed…and yet, now that they were here, right in front of the starting line, her nerves took over. This was the last chance she was going to get to change direction, so she had to say something.

"Maybe…maybe we shouldn't. You're Shouto's best friend! You have been for a long time, and I'm his older sister. It just…doesn't feel right to do this to him, on his birthday."

"Shouto would just want you to be happy," Midoriya insisted, scooting closer.

"I suppose…b-but there's still our age difference! I'm 7 years older!"

"And you're by far the most beautiful woman in this dorm right now."

She nearly crumbled from the praise, leaning her face into his hand when he lifted it to caress her cheek.

"You keep talking about being older like it's a turn off, but it absolutely isn't. Especially for me! I, uh…I sorta have a thing for older, more mature women…" He blushed.

Maybe he felt awkward admitting one of his kinks out loud like that, but that was the last piece of reassurance Fuyumi needed to know that Midoriya was serious about wanting her. He actually liked that she was older! And he was so sweet and hot and she knew he wouldn't let her family issues stop him from taking her…

So finally, at long last, Fuyumi couldn't find it in her to resist him for a second longer. She threw her arms around his neck and pressed their lips together.

Midoriya immediately kissed her back, and even though she was older and supposedly more experienced, she was the one following his lead as he wrapped an arm around her waist and tilted her back, laying her on her back as he got on top of her and made out with her, lapping his tongue against hers while his hands squeezed her curvy sides like he'd waited a lifetime to explore her sexy fully-matured body.

By the time their mouths parted, Fuyumi was gasping for air while Midoriya just grinned.

"M-Midoriya…" She moaned as he unbuttoned her shirt, then masterfully unclipped her bra and slid it off of her.

"Just call me 'Izuku' from now on. We've known each other long enough for that."

"Izuku…" His name rolled off of her tongue so perfectly as she savored the taste and feel of his saliva.

Even though she'd been naked with plenty of guys, there was something different about exposing her boobs to Izuku. Maybe it was because her feelings were more intense this time, or maybe it had something to do with the fact that this was her little brother's best friend. She couldn't help but try to hide her face behind her arm as Izuku leaned down and dragged his tongue across her tits, lightly pressing his face into her large boobs and just rolling his face forward into them.

When he moved on from her boobs, his hands still reached up to grope and squeeze them, clearly showing where his preferences were while he dragged his tongue down her chest, down her midriff, kissing her curves…

"I-Izuku! You can't just lick me all over!"

"Mmm, but what if I want to?"

She huffed. "You're surprisingly quite the pervert, aren't you?"

He chuckled and dipped his fingers into her waistband. "Guilty as charged."

Off came her shorts, and her panties shortly after. She was no virgin, so even if she was flustered and overwhelmed with intense feelings for Izuku, she wasn't shy of sex as she spread her legs for him.

He eagerly laid down in between her legs, breathing inches away from her pussy. The way he immediately prepared to eat her out had her raising an eyebrow.

"How many times have you pleasured a woman, Izuku? It's not everyday a man is so willing to go down on a girl like this."

He scoffed. "Are you kidding? This is my favorite part!"

Somehow, that was the biggest turn on of the night as she eagerly spread her legs wider.

"Sounds to me like you've just been with a bunch of assholes. Speaking of which…how many guys have you been with, Fuyumi?"

She blushed, slightly frustrated at having him so close to her pussy but continuing to ask her questions. "I'm not sure…I lost count after 9, but it's definitely been more than that."

He flashed her the sexiest smirk she'd ever seen before his eyes latched onto her wet, waiting pussy. "Well then, do me a favor and let me know how I compare to them."

Finally, he went down on her pussy, and he went down hard. This was definitely not the type of shyness she'd expect from a younger guy trying to eat pussy—no, Izuku dove in face first and eagerly wrapped his mouth around her pussy, as if treating her cunt as another pair of lips for him to make out with just as vigorously as he'd kissed her earlier.

She moaned and squeezed her thighs around his head, already panting for air as his tongue explored her walls, licking side to side before thrusting inside. His lips were puckered against her pussy in a constant sucking motion even as he tongue-fucked her, and he had one hand lightly squeezing her thigh while the other one wouldn't leave her boobs.

"I-Izuku! Wait…ahhh!" She gasped as he greedily slurped against her pussy, pulling his tongue out and licking up and down the curve of her pussy before he located her clit in what must've been a record time for guys all around the world. As soon as he found it, he latched on with his mouth and began sucking her clit, substituting the loss of his tongue with those rough, manly fingers of his, thrusting them into her pussy. The same scarred fingers that had slammed down both of her brothers during arm wrestling…

All in all, it was a nonstop attack on every sensitive part of her pussy, a combination of Izuku's mouth, tongue, and fingers working in tandem to worship and ravage her as Fuyumi's moans grew louder and louder. She reached down to grab a fistful of green hair, her other hand on top of his hand that was squeezing her boobs. It didn't take long before she was arching her back and cumming.

After the first squirt, Izuku eagerly opened his mouth and stuck his tongue out—such a thirsty and perverted display of his lust for her which only made her cum even harder, squirting all over his face with shaky gasps of ecstasy. His fingers continued to pump in and out of her pussy, giving her no time to breathe until finally her cunt had been milked, and he just gave it one last kiss before getting on top of her again to grope her boobs in both of his hands, nose a few inches above hers.

"So? How'd I do?" He wore a cocky grin on his face—he clearly already knew how good he was.

"Ha…it was amazing, Izuku…I've never felt anything like it before! Either you've practiced this many times, or you're just a natural…if I were to guess, the rumors Mina mentioned are true, aren't they? No one has ever tongued me like that and made me squirt so fast…"

He licked his lips and finally got off of her. "One of my many talents," he casually bragged while unbuttoning his pants and throwing them off along with his boxers.

"Holy shit…" Fuyumi cursed as his cock sprung free—fully hard, slightly veiny, and fucking massive in every way. The head hung slightly forward, as if his cock was just too heavy to hold itself up completely, and his balls sagged like sand bags too full for their own good.

"It's as thick as the sake bottles Natsuo brought…maybe just as long, too…" She observed in wonder, crawling forward to grip his cock in her hand. It pulsed with such heat and lust, as if expressing Izuku's sexual energy through touch.

"Bigger than your past boyfriends?" He definitely didn't need the answer to this one, but he just wanted to hear the praise, and Fuyumi gave it in spades.

"Fuck, it's so much bigger…it's even bigger than I thought was possible. It's the type of size you only see online or hear about in rumors." Her eyes were still wide with shock as she lightly stroked up and down his fat cock, squeezing lightly and licking her lips when thick globs of precum oozed out of the slit. "I can't believe there's such a huge cock on someone so young…"

Izuku sneered. "Didn't think you'd be such a size queen, Fuyumi."

She blushed and looked up at him. "I'm not…!"

"Shh." He patted her head and winked. "I was just teasing! This is how all the girls react. Obviously. Deep down, you all know you want the guy with the biggest cock, isn't that right?" He grabbed the base of his cock and swung it side to side, making an almost hypnotic sight as Fuyumi's eyes remained glued to it. "So go on, Fuyumi Just forget about your strict dad for tonight…because we both know you wouldn't be able to resist me, anyways."

The cockiness in his words made her moan as she squeezed his cock harder. "You're right…I can't resist…even if I were to think about my father not approving, I still wouldn't be able to resist! Izuku…let me show you what I can do."

She stroked her hand to the base of his cock, holding it steady so she could lower her mouth onto it. She took a few seconds to adjust to every inch before sinking down lower and lower, stretching her jaw wide apart until his thick head poked at her throat, and even then, she didn't stop!

"Fuuuuck, trying to deepthroat this monster on your first try? You're crazy, Fuyumi. Crazy thirsty for it~" He chuckled, resting one hand on her head to help her push her way down since she wanted even more of it still.

His cock was so massive and overwhelming that she felt like its taste and smell was clogging her nose as she deepthroated him, squeezing her eyes shut to just focus on pleasuring her man.

Her hands reached down to feel his balls, as if to make sure they were real. She swore she could feel the massive amount of seed he was storing—not just because of how heavy his nuts were, but the way his balls seemed to pulse in her hand was so erotic that it made her moan around his cock.

"Fuck, not trying to talk with my cock down your throat, are you? I figured you'd know better…or maybe it's because you know how fucking good it feels, feeling your voice choke and die around my huge cock!" He jerked his hips forward, making her give a strained gasp and a moan as she hollowed her cheeks in as much as possible to suck him off despite how stretched her jaw was.

Izuku sighed in pleasure, leaning back a bit, hands resting on the bed now while he lightly pumped his hips forward down her throat. "Even if you've never been with anyone my size, I can tell you've got experience…this is exactly why I love older, more mature women! None of the other girls could suck my cock the way you do, Fuyumi."

The praise—specifically regarding her age—made Fuyumi melt in delight, eager to pleasure him even more as she finally began bobbing her head up and down his cock, fondling and squeezing his balls as she turned her throat into the perfect fleshlight for him. He didn't even need to move, just rolling his hips forward for extra friction and grunting in lust as Fuyumi shoved her face down into his crotch, stuffing her throat full of so much cock it made her throat bulge before she was pulling back up to rest the head of his cock against her tongue. Then she went back down again, moaning around his cock while Izuku's relaxed hands clenched into fists on the bed.

"That's a good girl…take it all the way, show me how badly you want it! Do you have a thing for younger guys, Fuyumi, or is it just because my cock is so big?" He teased as she finally pulled off of his cock and stumbled back a bit, wiping her wet chin and massaging her throat and gasping for air.

"Mmm…it's more than just how big your cock is, Izuku. I'm definitely getting addicted to the youthful cockiness that only comes from younger guys with an ego to prove…"

"That's an oddly specific thing for you to be addicted to," Izuku mused, grabbing her by the chin and lifting her up so they could kiss again. "I wouldn't consider myself a super cocky person by any means."

She eagerly kissed him back before laying down, letting him crawl on top of her again. "I'd say it's the perfect amount. You're the whole package, Izuku…and the sexual confidence that you do have is because you can back it all up. I'm just…" She blushed as she looked up into his lustful green eyes. "It feels like I'm head over heels for you already…"

He grinned and kissed her some more before mouthing his way down her sensitive neck, making her moan. "You don't know how glad I am to hear that, Fuyumi…because for me, I've had eyes for you since day one. You were so welcoming and beautiful, like a silver angel…exactly how I like my older women."

She blushed even harder at that. "Izuku…ahh! Izuku! Oh, you're…" She moaned, spreading her legs as that heavy cock of his that should be legally registered as a weapon laid itself right on top of her pussy, leaving her breathless with anticipation.

"I've had countless dreams and fantasies of this moment ever since Shouto invited me to eat your cooking during first year. And every other time we've met since then, my desire for you only got stronger and stronger. It used to keep me up at night, embarrassed as I fantasized about sleeping with my best friend's older sister…but I've dreamt about it so many times that I can't even feel embarrassed about it now, even as I admit all of this to you…" His eyes were so intense, like he was staring into her soul as he poured his out to her, linking their fingers together and rubbing his cock against her pussy lips until the tip was pressing against her entrance. "So you see, Fuyumi, I don't give a fuck what your brothers or your dad will think. I want to claim you as mine no matter what, and if they have problems with it, they can go sulk about their own single lives."

"Fuck, Izuku!" Fuyumi moaned, trembling beneath him and bucking her pussy up to try and force his cock inside.

He chuckled. "Oh, you like that? You like it when I talk about how the rest of your family is just jealous of you? Because they're the ones living miserable, single lives while you're getting your pussy pounded by the cock of your dreams?"

For the first time, she felt like she maybe inherited some of her father's quirk, because her body felt impossibly hot all over. She was certain she would start to give off steam at any moment as she squirmed beneath Izuku with high-pitched gasps. "Yes…I-I don't know why, but it's so fucking sexy when you say things like that…I know it's weird, but…I've felt tied down to my family for so long, you have no idea what a burden it's put on me, even if I do still love them…"

He didn't keep her waiting any longer, finally pushing his cock inside of her. When she immediately moaned and begged for more, he grinned and slammed inside. "You don't want to take it slow at all, do you, Fuyumi?"

She shook her head, chest heaving as she held onto his muscular shoulders and took him deep inside of her pussy.

"There's an easy explanation for why you're so into this, Fuyumi. You're a good girl. You've always been a good girl…but it's about time you do something for yourself. Be a little rebellious. Fuck a man with a huge cock just to spite your family." Izuku egged her on, hitting on all of her recently discovered kinks as she moaned. With every dirty word he spoke about her family, her cunt clenched down as hard as possible around his cock, as if trying to suck him in even deeper. He gladly obliged and pushed his cock deeper inside, whispering directly into her ear with a playful smirk. "Does that sound good, Fuyumi? You wanna give yourself to a boy who you know will make your dad go crazy? You wanna fuck your brother's best friend, knowing it's gonna make things awkward for you and your brother? You wanna give yourself to the guy who just proved he was stronger than both of your brothers one after the other? You wanna give a giant middle finger to the men in your family by showing them that you belong to a superior man?!"

"YESSSS! Yes, Izuku, please! All of it…I want all of it! I'm…tired of being the responsible older sister, and the tireless eldest daughter! I just…want to be yours now! Take me…take me and make me yours…! I'm yours now, Izuku! Ahhh, I can't wait…to see the looks on their faces when they realize I'm yours!"

All three faces flashed in her head—Shouto's shocked eyes from the relationship between his sister and best friend, Natsuo's grumpiness at having to accept that she wouldn't always be around, and best of all was the image of her father's face completely lighting on fire as his 'precious only daughter' showed that she wasn't the delicate and pure snowflake that he wanted her to be…

She shouted in pleasure as she came, squeezing Izuku's cock even tighter as he fucked her through her orgasm. Her mind flashed through the images of her family realizing she belonged to Izuku multiple times before going completely blank, the euphoria of squirting nonstop for a minute straight while Izuku's fat cock continued to mercilessly pound her making her eyes roll back.

"You've been holding back a ton, haven't you?" Izuku observed with a grin, clenching his teeth ever so slightly as he briefly slowed his thrusting while her pussy, her body, and her entire brain slowly began to calm down from the overwhelming sensitivity of her orgasm. He caressed her cheek to try and bring her head back down from the clouds. "Not that I'm surprised. It does not look easy being the oldest sister in a family like that. No offense, of course."

She sighed in pleasure, leaning her face into his hand as she slowly drifted down from cloud nine. "It isn't easy at all…" She admitted, finally able to be vulnerable about this for the first time in what seemed like forever—and there was no better time for it after she just finished squirting her brains out to the rebellious act of giving herself to Izuku. "Things with my family have always been difficult, and I've always had to be there for all of them…"

"Shouto's admitted to me that you basically took up the matriarch role at a young age," Izuku sympathized, kissing her forehead and lightly rolling his hips forward with a moan because he was still buried balls deep in her pussy, and the tight, warm squeeze was still driving him crazy with lust. He held back the urge to plow her into another orgasm, though. She needed the mid-sex talk.

"That's true. It feels like everything I've done over the last few years has been for them…for the guys in my family." She sighed and then smiled up at Izuku. "I guess that's why it feels so good to finally…let go of some of my responsibility over them. To focus on what feels good for me. And I guess some spiteful part of me…likes the thought of making this as humiliating as possible for them? Does that seem weird?"

He chuckled and jerked his hips forward again. "Your brothers and your dad have been a pain in your ass for your whole life, so the thought of someone like me fucking you and emasculating them feels cathartic. Some people might think that's weird, but you can't control how you feel after years of going through what you've gone through. Besides…" He suddenly flipped them around so he was laying on his back, letting her sit on top of his cock. "I think it's fucking hot. And you think it's fucking hot. And that's all that matters now. Personally, I can't wait to see the shock on Shouto's face when he finds out that I finally got my hands on you."

She smiled down at him before rolling her hips, repeating the movement harder and faster as Izuku moaned from beneath her. Her hands were planted on his chest, feeling up his muscles and giving his abs the worship they deserved while her cunt clenched around his thick cock as she rode him. "I want to see it, too…I want to see how they'll react when they find out that I'm dating…and fucking…Shouto's best friend. I'm tired of being seen as the responsible caretaker of our house. I want…I want to be seen as your woman, now, Izuku. And I know it's going to make my father furious…"

Izuku half-laughed-half-moaned as she began riding his cock harder, making him roll his hips up to meet her while grabbing her hips. "He'll probably be even more mad knowing that he can't scare me away the way he's done to all your other boyfriends. Does that get you wet, Fuyumi?"

She blushed and desperately began grinding down onto him, making circular motions with her hips that made Izuku groan and thrust up. "Yes…before we came here, dad told me not to bring any boys home from the party. A stupid statement considering this was a party full of a bunch of younger boys only…" She smiled with an almost mischievous glint in her eye. "Now, I want to bring you back home just to show him that he can't control my dating life any longer."

Izuku seemed to be getting off on the idea of pissing off her family just as much as she was, his cock throbbing inside of her. "Fuck, that sounds fun…you know what sounds even more fun? Fucking in your bedroom!"

Fuyumi moaned as Izuku filled her mind with new fantasies. She rode his cock faster, leaning down so that she was on top of him on her hands and knees, her boobs squishing against his chest so they could make out while she kept slamming her cunt down onto his cock. "Fuck, yes! Defile me, ruin me, Izuku!"

He flipped them around again and immediately began pounding into her cunt even harder than before. "Fuck, I just can't hold back with you, huh? You make me go crazy, Fuyumi! It's so hot seeing a responsible, mature woman like you let the lust corrupt you!"

The word 'corrupt' made the whole thing even filthier as Fuyumi moaned, wrapping her arms around his neck as he shoved his face in her tits while fucking her. "I can't help it…I've waited years for this! For a man to make me his, who won't be intimidated by my father and who can throw that in their faces!"

Izuku was fucking her wildly, capturing her mouth in his as his orgasm quickly began to build. After all of the fucking they'd done, and with how heavy his balls had been, Fuyumi knew he was going to fill her like she'd never experienced before.

"You know what the perfect birthday present for Shouto would be?" Izuku had a smirk that could only be described as sinful. "Why don't we give him some nieces and nephews for his birthday?"

Fuyumi's eyes widened, and a rush of physical and mental euphoria rushed through her body as she arched her back. "Yes, please, fuck me, cum inside me! This is what I've wanted for so long…this is what I've needed…this is what they've needed! Make yourself the newest man of our family, Izuku!"

They maintained eye contact, full of love and lust as Izuku slammed into her with a newfound purpose and passion with every thrust.

"Fuyumi…"

"Izuku!"

"You're sure it was up here?"

"Yeah, I saw them going upstairs earlier."

The door to Izuku's room suddenly opened, and both Izuku and Fuyumi whipped their heads to the side with wide eyes as Natsuo and Shouto walked inside, flicking the lights on.

"Hey, Midoriya! We were just about to—" The two brothers froze at the sight in front of them, jaws dropping and hitting the floor as Izuku gave one more, hefty thrust without even thinking about it.

"Oh, fuck!" He cursed, eyes squeezing shut, but he forced one eye open to watch the hilarious expression on Natsuo and Shouto's faces as he shouted and bucked his hips forward. "I'm cumming, I'm gonna cum!"

Fuyumi briefly glanced at her two brothers, memorizing the expressions on their faces, before she wrapped her legs around Izuku's waist and linked her ankles together, locking Izuku deep inside of her, forcing his cock to shoot directly to her womb as she moaned.

"Do it, Izuku! Fill me…make me yours!"

Their moaning mouths met in a sloppy, tongue-filled make out session as Izuku pumped her full of his seed, groaning with every thick load that left him. He rolled his hips forward with each pulse of his orgasm, making sure the two brothers could tell whenever he shot another round of virile, built up cum into their sister's belly.

Fuyumi moaned the entire time, even as his tongue dominated hers. Her arms and legs clung to him, not loosening for even a second, keeping him glued to her as her pussy greedily milked the cum out of his cock with tight squeezes. Her own orgasm also washed over her, and in the end, her pussy was a complete mess of their mixed sex fluids.

Izuku had cum so much that the thick baby-making seed was flowing down her agape pussy, like a fountain of white drool leaking out of her.

Her eyes rolled back in bliss, taking one more look at her shocked brothers before falling shut with a deep sigh of satisfaction.

Izuku kissed her some more, laying his cock flat on top of her messy cunt before turning to the brothers again. "Are you two just gonna stand there? Don't you feel weird watching your own sister like this?"

They immediately backed out of the room and slammed the door shut, but didn't move any further than that.

"W-we seriously need to talk!" Shouto shouted from behind the door. Izuku had never heard him so flustered and riled up. How fun.

Meanwhile, it seemed Natsuo had shut up completely and was still speechless. That was fun, too!

"Wonder how Endeavor will react." He smiled when that made Fuyumi giggle tiredly.

"I never wanted them to actually see me naked like this, so once I'm cognizant again in the morning, I'm sure I won't survive the embarrassment. But for now…" She reached up and cupped Izuku's freckled cheek. "Thank you, Izuku. You're everything I could've ever wanted."

He smiled back at her, pulling the blanket up and then just watching as she fell asleep within the next minute. She was both physically and mentally exhausted.

There was another bang against the door, so with a sigh, Izuku got up, threw on a pair of shorts, and stepped out of his room to face the two brothers.

"What the hell did you do to her?!" Natsuo snapped, but Shouto held an arm out in front of his brother.

"Just hold on, Natsu. Midoriya…you're going to explain, right?"

Izuku crossed his arms and leaned back against the door. "Quiet down—your sister's trying to sleep. There isn't really much to explain, is there? You both saw everything for yourselves—your sister and I are a thing now."

Shouto narrowed his eyes. "Who came onto who? How did this even happen?"

"We came onto each other. We've both actually wanted this for a while. You don't have a problem with that, do you?" Izuku challenged them as the brothers glanced at each other.

"I just…never would've expected this from you, Midoriya," Shouto muttered.

"And I never would've expected this from Fuyumi! What is she thinking, hooking up with one of Shouto's classmates?" Natsuo grumbled, as if he still couldn't believe this was real. "I'm definitely gonna have to talk to her…"

"About what?" Izuku raised an eyebrow. "Fuyumi is more than just your housekeeper. She's her own woman with her own wants—you can't get upset at her for finally focusing on herself for once. Well, you could, but then you'd be an asshole. And I know neither of you are assholes, right?"

The passive-aggressive comments made both Shouto and Natsuo shrink back a bit, unable to reconcile their feelings of brotherly protectiveness with their feelings of brotherly support.

"If we're done here, then I have to go join her in bed. She'll be staying the night here with me." Izuku said, leaving no room for debate.

"Yeah, dad isn't gonna be happy about that." Natsuo sneered.

Ah yes, Endeavor, the big bad intimidating father figure who chased away all of Fuyumi's boyfriends. Izuku had definitely been intimidated by him for some time, but even when he was trying to stick up for Shouto during their first year sport's festival, he'd already found the courage to stand up to Endeavor since back then. The more time he'd spent with Endeavor under his tutelage, the more he'd learned that Endeavor's bark was worse than his bite. The man was too scared of becoming a bad person again.

"She's a grown woman—she can stay overnight if she wants. I'll bring her back by tomorrow morning, and when I do, I'll personally face Endeavor."

Natsuo whistled. "This feels super weird, but I respect the amount of balls you have. Well then, uh…take care of her, I guess…" Natsuo rubbed the back of his head before turning to leave.

Izuku would certainly take care of her, the way her family never did.

As he opened his door to slip back into his room, he noticed Shouto still standing there, staring at him. When he stared back, Shouto averted his gaze downwards.

"Midoriya…"

"Hm?"

"..." Shouto pursed his lips together. "Don't you think this seems…bizarre? You and my older sister…that's…"

Izuku rested a hand on Shouto's shoulder with his classic hero smile, though there was just the slightest bit of impatience. "That means we'll be like brothers from now on. I look forward to it. Goodnight."

Without another word or another glance, Izuku shut the door and joined his new girlfriend in bed, wrapping her in his warm arms. Even if the cold didn't bother her, Izuku would never let her sleep in a cold, lonely bed ever again.


Next morning, they walked into the Todoroki house hand in hand, where Endeavor immediately confronted them with fire all over his body.

"Fuyumi! Call me the next time you're going to make a decision like that! And you, young man!" He turned on Izuku with raging eyes. "What are you doing to my daughter?"

Fuyumi lowered her head, but Izuku squeezed her hand and even stepped forward. "Your daughter is her own person. She can spend the night wherever she wants."

That pissed Endeavor off even more—it'd been a long time since he'd looked so furious given he'd spent the last few years working on his anger issues.

Finally, Fuyumi stepped in. "Dad! Remember what we talked about the other night?"

Endeavor's angry face faltered. "I-I know, sweetie! But this is different! This is one of Shouto's classmates and he's also one of my interns! Doesn't that seem inappropriate?!"

"I'll be the judge of that!" Fuyumi let out something akin to a growl, eyes narrowed. It sent chills down Izuku's spine as she found her resolve. "I appreciate you looking out for me, dad. It feels nice after not having a dad to look out for me my entire life. But if you really want to make it up to me for helping you reconnect with the family, with Shouto…then you need to back off for right now and let me decide the course of my own life…because I've spent far too long letting your family name control my life."

Izuku felt like he could tear up as he pulled her closer to him and kissed her cheek. "I'm proud of you."

She blushed and leaned into his side before the two of them stared Endeavor down together.

Endeavor was still speechless, but his anger had subsided and now left nothing but…embarrassment? And humility?

"Now come on, Izuku. Let's go." She turned to lead him out of the house.

"Wait, I thought I was dropping you off back home?" He questioned as they stepped back outside.

She sighed. "That was the plan, but after a conversation like that, I think it's best we give both me and my dad some time and space, you know?"

He nodded before smiling and walking faster to take the lead. "In that case…how about we have our first date? I'll show you that I'm more than just a good lay in bed!"

Fuyumi blushed. "You're really not embarrassed to be seen in public with me like this? I know you're taller than me, but it's still obvious that I'm quite a bit older than you…wah?!" She gasped as he pulled her in, wrapping an arm around her waist.

The two of them stared long and hard at each other as Fuyumi rested her hands against his chest, face reddening. His green eyes looked so intense, glued to her own, relaying a silent conversation of a thousand words. Finally, she sighed, smiled and rested her cheek against his shoulder. "...alright. You're right. All that matters…is how we feel."

With another smile, Izuku nodded in satisfaction before pulling her along again.

Fuyumi followed him with a skip in her step, clutching Izuku's hand tightly in her own until all of her worries seemed to thaw around her as she clung onto him—the one that wouldn't leave her.


The plan was to make this not only about Izuku rescuing Fuyumi from the aftermath of how stressful the Todoroki family's situation was, but also to have him rescue Rei, the actual mommy of the Todorokis! Rei could definitely use the type of loving that only Izuku can give. So that'll be the eventual follow up chapter to this one. EVENTUALLY.
