They’re cuddling in the common room, enjoying the peace and quiet of the empty dorms.
Like most Saturdays, the majority of their classmates were out somewhere, and the few that remained were hanging out in their rooms.

Which gave them total freedom to contentedly snuggle on the couch.

adorable red nose that morning).
Izuku coaxed him into having a
lazy day by saying he didn't really feel like going out because of the cold weather. Kacchan immediately agreed because, according to him, “the nerd gets cold too easily and I'm ain't giving him my damn jacket!”

Izuku tried not to look too smug about it, but their friends' knowing stares made it very hard not to seem clearly satisfied with his Kacchan management techniques.
When everyone left after the breakfast rush the two guys were finally able to relax.

Earlier, Izuku put on the old All Might cartoon show that Kacchan and him used to watch in their sleepover as kids. Every time, Kacchan was out like a light before the first episode even finished, and this one was no different.
6
Izuku threw a blanket over them and Kacchan immediately snuggled to his side, falling asleep no more than 10 minutes into the show.
Izuku kissed the top of his fluffy hair and smiled against it.
Kacchan was so clingy when he wasn't feeling well.

He would never tell him (he appreciated his life, thank you very much) but the way the blonde needed constant attention, kisses, hugs and affection when he was feeling off was the most adorable thing ever; Izuku almost felt bad for loving it so much.
8
Of course he didn't like that Kacchan was sick, but having full permission to pamper him without Kacchan pretending to hate it was like heaven on earth for him.
It was an unspoken agreement between them. A sick Kacchan meant a needy Kacchan, and Izuku was more

than happy to give him anything he wanted and more.
Currently, Kacchan just had a bowl of steamy soup —brought to him to the couch so the princess didn't have to get up from his spot in the warm blankets— and is sleepily dozing off again in Izuku’s lap.

10
At first, he was very embarrassed to initiate any kind of contact between them. But now? The moment Izuku sits back down after doing the dishes and putting the leftovers away, Kacchan is all over him demanding his full undivided attention. No shame whatsoever.
11
“Kacchan,” Izuku softly laughs, “let me arrange the blanket so I can cover us both.”
“What the hell took you so long?” Kacchan angrily murmurs against his chest, quickly settling down in his righteous place in Izuku's lap, embracing him like a koala and finally resting his head

over his shoulder, tickling his neck with his cold nose. “I waited forever for you to come back, moron.”
Izuku wraps his arms around him and gently rubs his back over his shirt and under the blanket. “It was barely 20 minutes.”
“Too damn long,” he stubbornly repeats.

Oh well, who's he to deny him anything anyways.
“Im sorry, Kacchan. I'm here now,” he mutters, his other hand coming to cradle through his hair. His blunt nails delicately scrape over his scalp, making Kacchan shiver in response. He takes the opportunity to let his crooked

fingers pull softly at small strands of hair in the way he knew it made him relax. Kacchan melts against him, nuzzling his face impossibly closer to him and releasing a pleased sigh.
“Are you feeling better?” Izuku asks, turning his face to place a kiss on his boyfriend's

warm cheek. Kacchan unconsciously leans into it, making Izuku's heart squeeze inside his chest and speed up at the cuteness overload he was having.
Kacchan grunts. “I told you I'm fine.”

16
“I'll take that as a yes then,” the other boy replies, kissing him again for good measure. His other hand sneaks under Kachan's shirt to stroke his back and feel his soft, milky sking under.
And if Kacchan had the ability to do so, he would be purring.

“Dont think I don't know what you're doing,” he mutters, trying to sound angry but without any heat in his words.
“Taking care of my sick boyfriend?” Izuku playfully retorts.
The blonde glares at him. “More like getting your fill of me now that I'm too week to stop you.”

“You don't want me to?” the boy asks, already knowing the answer. “I can give you some space if that's what you want,” he innocently says, taking his hand off Kacchan's shirt and pulling the other one away from his hair.
The panicked, sad look Kacchan gives him at the loss of

contact is enough for Izuku to instantly regret his actions.
Kacchan likes to whine and complain about Izuku fussing over him whenever he's sick, but his tolerance for Izuku teasing him back in those moments is so low it's almost funny.

20
Izuku's hands fly to where they were before at the sight of his boyfriend's plaintive face, and all Kacchan does is give him an offended glare before going back to hide his face on the curve of his neck.
21
“I'm sorry, I'm sorry” Izuku whispers, kissing his temple in between apologies. “I'm not going anywhere, alright?”
“Don't you dare,” Kacchan threatens against his skin, lips brushing the sensitive pace and giving him goosebumps.
If Izuku didn't know any better, he would swear

22
Kacchan is giving soft, lazy kisses to his neck and trying to disguise them as talking.
Izuku hums and tilts his head to the side to give him better access, and Kacchan responds with openly dragging his lips through his neck now.

23
Open-mouthed kisses intermingled with little pecks make Izuku squirm in his place, tightly wrapping his arm around Kacchan’s —who's straddling him— slim waist.
“Don't get too excited, this is all I can do for you today,” Kacchan murmurs in his ear, kissing the shell

with wet lips.
25
“You don't have to do anything,” Izuku replies, forcing deep breaths out of his nose to keep from crumbling.
“I know. I wanna,” Kacchan easily says, “You look cute when you’re flustered.”
“So you’re only trying to fluster me, huh?” he replies, closing his eyes.

26
“Like you don't do the same,” he scoffs, dragging his nose across his collarbone. Izuku feels his grin.
Mmh, no. Can't do. Kacchan needs a taste of his own medicine sometimes, and Izuku loves holding the spoon.

“Can you blame me for babying you when I have the chance?” he asks.
He may as well take the bull by the horns.
Izuku turns his body and brings Kacchan with him, manhandling him until he's sure he’s right where he wants him.

28
His hands come to fondle his surprised face, thumbs caressing sharp cheekbones and puffy eye bags. Red eyes blink at him in question, but Izuku only smiles.
29
Slowly, he gets close enough for his lips to brush the tip of Kacchan's nose in a tender kiss, then he moves them to his cheek, patiently taking his time to press a trace of gently given kisses to his flushed face.
30
“I love to take care of you,” he mumbles, allowing his breath to caress the rossy skin. “I’d pamper you to death of you allowed me to.”
31
Kacchan, taken by surprise and disarmed by his boyfriend's adoring words, becomes limp in his arms, only being held upright by the big hands on his face.
32
“You're so beautiful when you're like this, all needy and bothered because you're a little sick. What kind of boyfriend would I be if I didn't crumble to your feet at the sight of that?” -
33
Izuku whispers and pulls apart, looking at him like he was the most wonderful thing he'd ever seen. “You're made to be taken care of, made just for me.”
34
Kacchan gulps, and his eyes become hazy and half-lidded. His lips part and his breath slows down as he desperately tries to chase the soft mouth that was on him a second ago.
Ah, Izuku has already won this round.
Ah, Izuku has already won this round.
35
He delicately tilts the blonde’s head a little so he can reach his ear and whisper, “Will you let me, baby? Treat you like you deserve?”
36
A broken whimper escapes his mouth but he doesn’t seem to care too much about it. Kacchan rapidly nods, suddenly turning shy and needing to hide his face in the safety of Izuku’s neck again, shaking.
37
“Oh, sweetheart, thank you,” Izuku coos, letting his hands roam back to his waist and belly. “You’re so good.”
38
Kacchan whines in his ear, tangling his fingers in wild curls. His hands are warm due to the oversized sleeves of the hoodie he’s wearing, now sliding up his arms and revealing the pale skin there.
Izuku wants so badly to sink his teeth into it.
Izuku wants so badly to sink his teeth into it.
39
He fights the urge by scraping his canines over what he can touch of Kacchan’s jaw, pulling another breathy mewl out of him.
“Why are you hiding?“ He gently asks, squeezing his waist. “Are you embarrassed?”
“Why are you hiding?“ He gently asks, squeezing his waist. “Are you embarrassed?”

Kacchan softly nods, pressing himself into him like they could fuse together.
“There's nothing to be ashamed of, Kacchan. I love you,” he says. “It’s only me, it's okay.”
“There's nothing to be ashamed of, Kacchan. I love you,” he says. “It’s only me, it's okay.”
41
The blonde takes a sharp breath before coming out of his hiding spot, with messy hair, his pupils blown out and red cheeks.
He pouts, and Izuku immediately knows what he wants. He raises an eyebrow and smirks. “You're gonna make me sick, too.”

42
Kacchan’s pout wobbles. And, if in a normal day the blonde doesn't handle well being denied anything, when he's in this fragile state, telling Kacchan no it's like watching a puppy get denied a treat.
43
Izuku's lips quickly make their way to Kacchan’s, pressing into them with all the love he is feeling.
He has a weak spot for Kacchan, always had, and always will. It's much easier to indulge in it now that they're together, and it makes his heart happy and peaceful.

44
They lazily make out for a while, not rushing into anything and enjoying the moment.
Izuku doesn't have any intention of taking it any further, but they still slowly and shallowly rut against each other just to feel closer and tingly all over.

45
Kacchan pants, and Izuku takes the opportunity to go back to his neck. He loves the smell of Kacchan's skin, even more when he smells only like himself and his detergent because he's been buried in blankets and cushions. It's sweet and musky. It drives him insane.
46
“Do your friends know how spoiled you are?” he murmurs. “How much you really like to be fussed over like this?” Kacchan gasps when Izuku licks a wet line behind his ear. He shakes his head to say no. “You can't lie to me, baby, I know all about you.”
47
Kacchan begins to rut his hips more forcefully, chasing the pleasant feeling building in his belly.
Izuku is quick to still his hips by holding them in place with the strong grip of his hands, digging his fingers into the flesh under his hoodie.

48
“Izuku,” Kacchan cries, voice hoarse and eyes teary under his knitted eyebrows.
49
“No, Kacchan. You have to rest,” he gently scolds him. “I’m sorry, baby. You always feel terribly dizzy after doing this when you're sick. We can’t,” Izuku pecks his trembly lips and suffers at Kacchan's pained expression.
50
Izuku hates himself because he should have stopped the grinding when it started, but he got too carried away and lost himself in the pleasure.
51
“Please,” he pleads, tears rolling down his cheeks and hands making handfuls of Izuku's shirt. “I need it, Izuku, please. I'll be good, I promise, I'll do anything you tell me to,” he whimpers.
52
And he really should be resting. Izuku really, really should not let him push himself like this.
But when Kacchan lets out another breathy cry followed by a sniffle, it makes Izuku's chest ache with the need to indulge him in anything he asks.
To /please/ him.

53
He handles saying no to Kacchan as badly as Kacchan does being told so.
Izuku sighs, pressing their foreheads together. “What I'm I gonna do with you?”
“Make me cum,” Izuku shoots a look at his boyfriend and he softly adds, “Please.”

54
Izuku ponders for a second.
“You know, that's actually a great idea,” Izuku replies, giving him a side smirk.
Kacchan doesn't have to do anything. He can take care of everything the blonde needs to feel good without him needing to lift a finger.

55
“You don't move, okay? I'll do it for you,” he presses a gentle kiss on his lips and Kacchan just blinks in response.
56
Izuku makes sure his hands are firm on the blonde before he starts moving Kacchan’s hips like before, but making sure Kacchan is nice and comfortably still.
57
Kacchan quickly realizes what Izuku's plan is, and groans as he lets his head fall in the crook of his neck once again, completely limp and pliant.
58
Izuku won't lie and say he's not enjoying this a little too much, but he guesses it's alright based on the pretty little moans Kacchan is making and trying to muffle against his skin.
59
It doesn't take long before they're both panting and Izuku's arms feel on fire, but, if anything, it only riles him up even more. Kacchan squirms and sometimes tries to move on his own, but Izuku is quick to remind him that is none of his business.
60
Soon enough Kacchan is whining in a way that lets Izuku know he's really close.
61
“How are you feeling, baby? Almost there?” Izuku breathes, also pretty near to his climax. But that isn't what he's working so hard for, so if he gets to cum too, he'd be pretty lucky.
62
Kacchan often becomes non-verbal when he's overwhelmed like this, so it's not odd when he can only nod in response and cling tighter onto his shoulders.
63
“I'll get you there, don't worry,” Izuku promises, kissing the side of his head.
With a small percentage of OFA, Izuku makes his moves faster, grinding them together with enough force to add pleasure but not to make it painful.

64
“Kacchan,” Izuku can't help but moan, biting his lip so hard he tastes blood.
“‘zuku,” he slurs, way too gone to think straight. “I- I’m—”
“I know, I know,” Izuku mumbles, kissing everything he can reach. “It's okay, Kacchan, I have you.”
“‘zuku,” he slurs, way too gone to think straight. “I- I’m—”
“I know, I know,” Izuku mumbles, kissing everything he can reach. “It's okay, Kacchan, I have you.”
65
Kacchan digs his nails into his bicep, and growls a silent cry when he finally cums. That's enough to send Izuku tripping over the edge too, making him cum right after.
66
They stay there, panting and recovering from their highs still in each other arms. Izuku goes back to drawing patterns on his boyfriend's back, whispering praises and love pledges only for his ears to listen.
67
“I'm dizzy,” Kacchan mutters.
Izuku laughs. “I told you. Do you want me to go for the trash bin?”
“No,” he replies, nuzzling in his chest like a tired cat. “Stay with me.”
Izuku laughs. “I told you. Do you want me to go for the trash bin?”
“No,” he replies, nuzzling in his chest like a tired cat. “Stay with me.”
68
Izuku's heart flutters. His boyfriend is so cute. He places a peck on the crown of his head. “Whatever Kacchan wants.”
“I want to nap and then shower.”
“That sounds great to me.”
“Were awfully gross,” Kacchan groans. “I can't believe we just did this here.”
“I want to nap and then shower.”
“That sounds great to me.”

69
“Well, someone insisted. Who am I to say no?” he grins. “I'm weak-willed against you.”
“Yeah, yeah, whatever,” he dismisses, getting ready to sleep. “We're gonna have to flip the cushions before leaving.”
“Yeah, yeah, whatever,” he dismisses, getting ready to sleep. “We're gonna have to flip the cushions before leaving.”
70
“That's…” Izuku pauses. Ugh, they are pretty gross, their classmates would hate them, “probably for the best. Yeah.”
Kacchan breathes a chuckle and rubs his cheek on him, drowsy and tired enough to fall asleep in a few minutes.

Izuku pets across his head and smiles.
He guesses taking care of his sick boyfriend has many benefits in the end.

And if the rest of their classmates came home early because the movie theater was closed, they would never know.
73
Little extra?
Thank god Ochako and Mina were the first ones to get there, having enough time to run back outside and convince the everyone to go and get snacks to the grocery store for an improvised movie night.
What a shame they flipped the cushions again before that.
