Work Text:
Sero always seems to be happy and cheerful but a lot of the happiest people are quietly the most insecure, which brings us to today.
You watch as a guy hands a note to Sero as he walks from the lunch line. Sero’s eyebrows furrow as he opens it and you stiffen slightly when you see his face fall. The rest of the Bakusquad are already sitting and didn’t see what happened.
You watch as he hurriedly stuffs the note in his pocket before going over and tossing his food taking off in the direction of the bathrooms. Immediately you stand up “Hey guys I have something to do. Foods up for grabs, I’ll catch you guys later”. They look confused but nod, “Okay see you” Mina and Denki wave bye, you hear them ask about Sero as you walk away.
You walk over to the mens room as he slips in and look both ways before following. Luckily it’s empty and you lock the door. “Sero sweetheart?” you see him leaning over a sink, a sad look on his face as he looks up at you in slight shock.
“I- um what are you doing in here it’s the mens room?”
“I saw what happened with the note”
“Oh. You saw that?” he sighs running a hand over his face, “I-it was nothing just some stupid prank or something, I'm okay see?” he plasters on a smile that clearly doesn’t reach his eyes.
“Hanta you’re not fine. Something has been weighing on you for a couple months and I have a feeling that note has something to do with it.” you move forward and take his hand.
“Please tell me what it is, Hanta” he sighs again, his eyes watering as he pulls out the note, he puts it in your hand as he looks at the ground, “I’ve been getting notes like these for a while.”
Your eyebrows furrow as you uncrumple it and pull it up so you can read it.
How did someone so bland and useless get into U.A let alone Class 1-A. Who'd you bribe to give you that spot? You'll never be good enough to be a hero so just give up already. A desk job is the only place your freakish elbows will ever be useful. -Someone better than you.
You immediately look up once you hear a sniffle. Sero is rubbing his eyes and running a hand through his hair. “Damnit. I'm sorry I'm being such a baby, it's just he hit every single stupid insecurity I had with this one”
“No you are not being a baby, love. This note is fucked up and you've been getting shit like this for months?” you move forward pulling him in your arms. He sounds so choked up.
“Let it out sweetheart” you rub his back as he lets go sobbing softly into your shoulder. Your eyes well up not being used to Sero crying or being so upset. You hold him tighter stroking his hair as he hiccups.
“Fuck I'm sorry I just-” he exhales shakily “I just don't know how he knew everything that bothers me so much. He knew everything that would hurt me and went for it” he hiccups a couple more times as he presses into you.
“Don't apologize, love please?” You lean back and press a kiss to his forehead. “I'll take care of this and-” you get cut off as the bell rings signaling lunch is over
“Shit we have to go to class but I'm gonna come over to your dorm after I do something once schools over okay love?” he nods, wiping his eyes once more.
You hold out your hand “Ready to go?" he takes your hand and you both walk out. You, of course, received looks since you were in the boys' bathroom but ignore them.
~Timeskip~
You've been looking for the guy that passed Sero the note, just as you're about to give up you see him with a few class 1-B kids. They look annoyed, hell even Monoma looks like he doesn't want to be talking to him.
You walk over and tap his shoulder kinda harshly. “Hey, we need to talk” TetsuTetsu and Kendo look at you kind of relieved and confused. Shinso sighs in relief at your interruption.
The guy turns around, he's shorter than you kinda buff though for his height “What do you want” he says snottily, his voice higher than most and nasally.
“You handed my boyfriend a note at lunch. Apparently you've been doing it for a while. I'm just here to tell you to stop” you sound stern, your face hardened with anger as you remember what it said.
The Class 1-B kids watch curiously wondering what's happening.
“Oh you must be elbow freaks girlfriend. What makes you think I'm gonna stop cause you said?" he looks smug
“Because I don't think you want to have your ass handed to you by a girl. So you're going to stop because you don't want to get your ass kicked”
“Awww boohoo like I'm afraid of you, yeah whatever” he rolls his eyes.
“Look I don't care what you say but it's none of your business”
“Like hell, it isn't. Motherfucker I'm not playing with you. You're gonna stop or I'm going to kick your ass” you stand slightly closer to him.
You exhale and back up “I don't have time for your shit. Stop with the notes or else” you turn around and just as you go to walk away, the dumbass speaks up.
“Yeah whatever not my fault your boyfriend's a useless bland nobody. People like him might as well just drive off a cliff or something and hope for a better quirk in their next life.”
Before you can even think you spin and send your fist into his face. He gets thrown a couple of feet and falls on his back out cold. The other 4 kids look shocked, to say the least. TetsuTetsu has his phone out obviously having been recording.
“Holy fuck” Shinso is the first to speak up. You exhale seething in anger as you run a hand through your hair. “I'm so fucked”
“Yes you are” you stiffen immediately as Mr. Aizawa’s voice comes from behind you. He didn't hear the conversation all he saw was you punch him. “You four also come to with me, we're going to need your statements”
You walk to Principal Nezu’s office still shaking with anger as the other four follow. All you can think is Please don't screw me please don't screw me.
You know Kendo and TetsuTetsu at the very least won't throw you under the bus but you don't know about the other two.
Everyone gives their statements and TetsuTetsu shows Aizawa the video. After you completely explain what he said you get let off with a 3-day suspension and extra chores. The student you socked is actually in more trouble than you and will most likely be expelled or suspended for a while.
After saying your goodbyes and heading back to the dorms you get confronted by most of the class.
“Is it true you socked someone?"
“Are you getting expelled?"
“I heard some 1-B kids were there, did you punch one of them?"
You look around at the crowd kinda overwhelmed. You just want to go take care of Sero and now this. You appreciate their curiosity but still.
“Uhhhh”
“Hey extras fuck off give her space” Bakugou thankfully saves the day. You give him a look of appreciation as everyone backs off.
“I have to say, Y/n punching someone is not responsible for an aspiring hero” Iida says as he looks at you sternly.
“If you heard what he said and knew what he was doing I think you would have punched him too.” you grumble annoyed he's going to probably lecture you.
“Who’s he and what’d he say?" Momo asks as she looks at you.
Just as you go to answer Sero speaks up from behind them, “He’s been harassing me for a few months” he sounds exasperated and almost embarrassed. Sero figured out he was the one you punched after you saying you’d handle it and disappearing after class the way you did. He also knows how protective you are of everyone in class 1-A, especially him.
“What?!” Kiri, Mina, and Denki say as everyone looks at him. He scratches the back of his neck awkwardly.
“The guy’s been, I guess, bullying me for the last few months, Y/n just happened to catch him and well I guess she told him off annnd punched him” he chuckles awkwardly already wanting the floor to just swallow him whole.
“What? Why didn’t you say anything?” Jirou says her face and everyone else’s filled with concern.
He sighs, “I didn’t want to bother anyone with my stupid problems. I was gonna handle it at some point but I guess I won’t have to now” he runs a hand through his hair nibbling on his lip anxiously.
“Aw Sero” Mina sounds sympathetic as she goes and hugs him.
“Your problems aren’t a bother nor or they stupid if you ever have a problem like that, tell us okay?” you smile when you see Sero’s lips quirk up.
“Okay thank you” he grins hugging back before they both separate.
Mina walks over to you “I wish I could have seen you punch that jerk” she giggles punching your shoulder playfully.
“Well TetsuTetsu did record it soooo” you grin smugly as Mina and Denki both fist the air happily.
“Hell yeah I’ll message him for a link or something” Denki says giddily.
You guys all talk about it a little bit more before you remember your plans for Sero and stand up, “Welp I’m gonna go to my dorm guys, I’m tired and I got extra chores to do tomorrow so yeah” Sero knows what's up and follows saying he has some extra credit assignment due and you both end up in the elevator going up.
“Thank you Y/n, for defending me and stuff” he smiles and interlaces your fingers holding it up to his chest.
“Anytime love and I mean that okay? You ever have a problem I’ll always be there for you”
“Thank you mi sol” he has a warm bubbly feeling in his chest as he shifts so he’s in front of you and leans in to kiss you passionately. You smile a little bit into the kiss as you wrap your arms around his waist pulling him in. “Anytime mi Cielo” and you go back to kissing him.
You can feel him press his hips closer to yours rubbing against you. You pull back slightly your lips still touching, “Fuck I love you so much” you kiss him again as he puts his arms around your neck, moaning softly against your mouth. Just as the kiss starts heating up you hear the ding of the elevator and you both separate, small grins on your faces as you both get off and go to his dorm.
Once inside you shut the door, locking it and pull Sero by his wrist into your chest and kiss him again. He smiles into the kiss pressing closer so you're pressed against the door. You move your hands to the back of his thighs and pick him before spinning him around and pinning him to the door.
He pulls back, “Fuck Y/n I forgot how easy it is for you to do that” you give his thighs a teasing squeeze and raise your brows playfully before kissing his nose with a chuckle.
“So is this what you had in mind when you said you were coming to my dorm earlier?” you nod as you turn around and walk to his bed. The bed creaks as you set him down and immediately climb on top of him. You pull off both of your shirts and throw them off to the side as you kick off your shoes.
“I’m gonna take care of you today okay? Today is all about you love” you smile softly and lean down kissing the side of his face and jaw. His breathing jumps up as you kiss down his neck and nip leaving small marks down his neck.
You start mumbling praises after each kiss.
Beautiful *kiss* Handsome *kiss* Amazing *kiss* Incredible *kiss*
He whimpers his face bright red and his hands clenched in the blankets. “Y-y/n” he moans softly when you suck hard on his sweet spot near his collarbone. You smirk against his neck before continuing down his chest, you pull one of your hands up and tweak his nipple taking the other in your mouth biting lightly. His back arches as he whines quietly, “O-oh fuck.”
You suck a little bit more before moving back. You take one of his arms and kiss down it paying special attention to his elbows, kissing around it. “You’re so handsome and strong my love. You’re so amazing.” He whimpers his eyes watering as he sniffles. You kiss up his arm again getting on top of his.
“My gorgeous hero” you reach your hand down and take off both your pants and underwear.
“Mi amour” he whispers, his voice cracking slightly as he looks up at you. He’s so gorgeous, watery eyes, a small bit of drool, bright blush, and a quivering lip. “P-please” he whimpers out quietly.
“Please what darling?” you ask as you brush a piece of hair out of his face.
“Please, keep making me feel good” he looks up with a pleading look on his face as he pushes his hips softly up against you. He turns away slightly, his face reddening even further.
“Of course sweetheart anything for you” you grin and grind against him, “How do you want it?”
“Uhm can you use the strap?” his voice raises in pitch by the end of it like he’s super embarrassed about it.
Your smile widens as you lean over and reach under the bed into the box of toys pulling out the massive, pink, vibrating dildo, lube, harness, and another toy he has yet to see, “Sounds good to me.” You lace up the harness and attach the dildo to the front. The dildo has a vibrating function so the dildo vibrates against your clit at the same time it vibrates inside him. It’s a massive dildo, and his favorite because it hits all the right spots and in the right position makes his washboard abs bulge when you thrust in.
“I wanna try a new toy on you today baby is that okay?”
“O-okay” he looks nervous and excited at the same time. A bead of precum is forming at the tip of his dick as you move his legs to be more spread around you. You grab the sounding toy from your right and slick it up.
“Is this okay love” you show him what it is and his eyes widen and his hips shift against the bed nervously.
“Y-yes but uhm you promise to stop if I ask?”
“Yes you feel any bit uncomfortable and want to stop or pause, just tell me immediately okay love?” He nods a smile on his face, all he can think about is how lucky he got with you.
“Okay Imma go now” he nods again and you hold his cock in place as you put some lube on the tip and then place the toy at the tip of his cock. He holds his breath as you slowly insert it. After he gets over the initial feeling he moans softly his breath hitching in his throat.
“Ohhhh fu-ck” he whines as you twist slowly the ribbed parts hitting sensitive spots nicely. He keens loudly as you move it further his back arching.
“F-fuck so good I- fuck” he thrashes softly and you pause making sure you don’t overwhelm him as he pants.
“You okay to keep going?” he nods rapidly, “Yes- fuck- please” he bites his lip as you push it in the rest of the way slowly a needy sound coming from the back of his throat. The toy in question has a ball at the top to keep the toy from sliding in all the way so you can let it go.
You grin again as you slowly pull it up with an up twist, you expected noises, of course, you know how sensitive this makes guys feel but his reaction fucked you up. “O-oh oh Y/-m-mommyyyyyy~ please oh god,” your eyes widen your breath hitching. He’s never called you that, not that you’re complaining, quite the opposite actually.
“Fuck, feel good babyboy?” you lean down nipping at his thighs as he arches his back.
“Y-yes so good, so good, fuck more” his eyes roll back when you tug it out a little faster, as soon as the end leaves his tip, his mouth opens in a silent scream and eyes shut as he cums onto his chest.
“Holy. Shit” his breathing is the only thing filling the room as you look down at him in shock. He came just from that tug, holy fuck.
“Sero? You uhm you okay” You lean over him stroking his hair after setting the toy off to the side.
“Good? I feel f-fucking amazing” he giggles his words slurring slightly.
“You wanna continue love?” he immediately nods before leaning up and catching your lips in a heated kiss. You languidly make out for a few more minutes before both of your arousals catch up to you and it becomes intense. You glide your hands up his body before gripping his hips and tugging him into your lap.
“You are so fucking gorgeous... So sexy baby” you kiss down his jaw as you hold him to your chest. He moans into your throat as you bite down hard on the space between his shoulder and neck.
You reach a hand down to grab the lube and coat your fingers so you can prep him. Sero whines when you rub the tip of your middle finger against his hole. He grinds down trying to get you to enter him faster.
“So needy aren’t ya?” you smile smugly as he nods and makes another needy noise in response. Deciding to be merciful you slip your finger in and rub against his inner walls, causing him to sigh in relief as he pushes back against your hand. You lay him down for a little bit.
Taking his thigh into your hand, you lean down leaving several marks on his inner thigh. “Beautiful strong legs”. You put his leg down and add another finger before taking his hand into yours, “Such delicate but strong hands” you kiss his knuckles and proceed to kiss up his arms again. You kiss even more softly around the opening for his tape knowing it gets sore from use sometimes. He sighs in content, his toes curling as you add a third finger.
“Oh god mommy, you make me feel sooo good~” he looks down at you and spreads his legs further for you, “Please, I’m ready”.
“Okay Hanta-baby” you pull out your fingers and lube up the dildo before picking him up again and hovering him over the toy.
“Ready mi Cielo?” you look up at his flushed face as he bites his lip, “Yes please fuck.” You help lower him onto it by gripping his hip in one palm and angling the strap with the other. You watch his face which is turned up in pleasure. The moment he reaches the hilt you look down at his stomach seeing the nice bulge the toy makes in his stomach. He moans loudly as he rocks softly in your lap trying to adjust.
“F-fucK mommy I feel so full~” his eyes cross slightly as a particular grind causes the fake cock to brush his prostate.
“Move whenever you’re ready baby boy” you lean forward slightly and kiss his adams apple and leave a mark on it.
After a couple seconds Sero lifts up on shaky legs and drops down, a loud and long moan leaving his lips. He keeps going, building up a rhythm. You grin snarkily and reach in between you both and flip the switch, a moan getting caught in your throat as you feel the vibrations against your clit. Sero’s back arches and jaw goes slack as he basically screams, his entire body shaking and his fingers scratching your shoulders.
“Oh fuck fuck fuck, FUCK mommy feels so good.” drool and tears of pleasure leak down his face as he goes faster and leans forward pressing your foreheads together.
“Mommyyy~” his eyes roll back as you thrust upwards. He goes mostly limp in your arms, his hips attempting to grind onto you. You groan as you start to feel yourself get closer to the edge.
You hold his waist and turn over placing him on his back. Grabbing his legs and putting them on your shoulder, you give him a look of warning before you start rapidly pounding into him. His hands reach above his head gripping the sheets tightly as he moans aloud.
“Oh god I’m close m-mommy I’m so close.” he looks up at you teary-eyed, his bottom lip quivering, “Mommy I-i’ve been a good boy p-please can I cum” he whines.
“Yes you can baby cum whenever you want” he keens his back arching as more and more whimpery noises leave his lips. You groan again, your own thighs shaking a bit as you feel the heat in your belly increasing rapidly.
Sero’s hands reach up, clawing at you and pulling you down “Kiss, kiss please, pretty please” he whimpers his voice trembling as he cries some more.
“Shh shh baby I'm right here” you lean down and kiss him passionately he holds you close his legs moving from your shoulders to your waist, holding you closer. You move a hand down stroking his cock, his hips jerking into your hand
He pulls back his lips against yours as he cums with a high-pitched whine, he grips you tight as he lurches with every stripe of cum shot out of his cock. You groan into his neck as the knot in your stomach snaps and you cum too.
You quickly flip the switch on the toy, undo the clasps tossing the strap off to the side before scooping up a crying Sero and holding him in your arms. He cries softly into your shoulder hugging you close.
“You okay sweetheart?” you ask your lips pressed against his temple. He nods softly humming in content before clutching tighter onto you. After a minute or two, you feel his shaking begin to cease.
“F-feels good still” he murmurs into your shoulder.
You smile softly before laying down moving Sero with you to lay on your chest as you pet his hair. You use a rag you left on the side to clean up the mess from between you two and toss it to the hamper.
“Thank you mi sol, for everything today,” he says into your neck as he shuffles closer to you. You lean over and kiss his head one last time before going to sleep
“You’re extraordinary mi cielo” you smile as you hear his breathing even out and you soon follow him into dreamland.
