Hey look its some poly!Erasermic headcanons that nobody asked for :3c

If Yamada is the energy in the relationship, then Aizawa is surely the sensibility. He easily balances out most mischief you and Yamada might get yourselves in, if only because he doesn’t want the two of you to get yourselves into any definite trouble--he already has enough to deal with when it comes to his own students. 

The majority of the time, Yamada is the more physically affectionate of the two of them, often more than happy to kiss, hug or hold you even if he’s at work. Aizawa is a little more reserved in public displays of affection, but he’s not cold. He often makes little remarks to both you and Yamada, but he means it only in jest. “The two of you act like lovestruck high schoolers.” Plot twist: Aikawa often feels like a lovestruck high schooler when he sees either of you, even if he isn’t the most audible about those feelings.

Due to Aizawa’s more subtle approach to the relationships, there’s a long period of time where his students actually think that you’re having an affair with him--after all, Yamada is far more open about being with you, so what does that make Aizawa? It isn’t until one of them (IIda) brings it to the attention of the principle that, hilariously, he has to explain to the class that he’s in a relationship with both you and Yamada.

It takes like a week for them to get over it. On at least three occasions they asked if you three were going to get married. While you personally enjoyed the student’s positive enthusiasm for their teacher’s loving relationship, it only put Aizawa in a sour mood for a few days, if only because he didn’t like so much attention put on it. God forbid he actually start wearing a wedding band in class, he’d never be able to get a lesson in without the entirety of the student body in class 1-A trying to ask about it and learn more about you.

In terms of being romantic, both of the men are rather equally matched, though they show their romantic nature in different ways. While Yamada is far less ashamed or bothered by social correctness or being embarrassed by going all-out to surprise you with a gift, Aizawa is much fonder about subtle, private moments between the three of you. Secret vacations and quiet dinners are much more his style of things, especially since it means there’s a far less chance that the three of you will impromptu get yanked into taking in a villain they encountered somewhere in the city, knowing their luck.

At first, there wasn’t a lot that changed about your daily routine. Aside from the offhanded comments about planning or the too-gentle press of his hand over your belly before the two of you fell asleep, being pregnant didn’t bring much change to your life--at first.

The first month or so went by with little difference, but by the third month, the bump of your belly had swelled enough to see that something was different. Though it took the right angle to notice, there was a definite baby-bump forming, gently pushing your shirts and making your pants feel a tad too tight. It was also then that your lover’s behavior too began to change. 

No more were the unspoken glances or the silent ponderings--Shouta had since moved into being vocal with them, obviously ready to start planning for the new little hero-to-be forming inside you.

“You should consider staying at home soon,” He may murmur into your ear in the early mornings, when both of you were getting ready to attend your jobs at the school. “I don’t want either of you to get hurt--the term is ending soon anyway.”

It was a suggestion instead of a command, but one where you could make your own final decision. Regardless, he would start to comment on purchasing furniture, clothes, or even how Yamada coos and rambles on about his best friend being a dad. Regardless, there’s nothing but fondness and warmth in Shouta’s voice each time he mentions anything. 

The two of you continue to sleep tucked up against one another, his hands protectively pressed to your growing belly, his face nuzzled into the back of your head. 

By the time you’ve hit the end of your second trimester, you’re on maternity leave. Though you’ve stopped officially working, it’s still nice to visit your lover for lunch, standing outside the door to the classroom and watching him give the students some level of hell or another--you can see the way he likes them though, the respect he holds in his sleepy eyes even when he’s otherwise dolling out punishments. 

He’d be a great dad.

It’s not until you’re round and heavy, sometimes having troubles moving around, that the two of you start discussing the fineries of the child themselves.

“I wonder what sort of quirk they’ll have,” You’d muse, laying back against the man’s chest, his arms wrapped around your shoulders. “One like mine? Or maybe even one like yours?”

“Who’s to say,” Shouta shrugs, seemingly aloof to the question, though you know it’s been in his head for weeks. He holds you tighter, pressing a kiss to the top of your head. “We’ll love them regardless.”

A giggle moves past your lips as he hums, a lazy noise that seems nonchalant, but has no shortage of nefarious purpose when you tilt your head back and gently press your lips to his. 

“You have work early tomorrow,” you murmur against his lips, eyes having barely a moment to glance at the nearby clock.

“What can I say,” the man says lowly, shifting his hands, one to your belly, and the other slowly pulling you up his lap, so he could start slowly, firmly start grinding himself against your ass. “You look so damn hot like this. Round and pregnant. Wanna mark you up.”

He wound up taking a sick day for completely important purposes.

Kirishima jelaous meaby???

The two of you had been together for months. A long time, honestly, longer than what most couples might be in that turbulent time in your lives. A time where you both should be focusing on finals, on graduation, of keeping up your grades and getting the best connections with pro-hero agencies to secure a good job, but the two of you managed to stick together despite all of the stress.

It was probably how you both got through so easily, having one another to turn to, to vent to, to talk to when things got bad. You had one another to lean on.

Despite it all, Kirishima couldn’t deny the feeling of a rock in the pit of his stomach whenever other guys got too friendly with you. He certainly didn’t care about the friends you made--the two of you were allowed to have friendships outside of one another after all--but there were times when some of the guys, particularly from other classes, got a little...too friendly for his enjoyment.

At first, the young hero didn’t notice any sort of discomfort from their, admittedly, harmless attention. In all honesty, Kirishima figured that he may be acting a little overbearing, perhaps thinking things over too much, and did his best to keep his distance or be overly-aggressive.

But no matter how much he tried to keep his thoughts at bay, Kirishima couldn’t help the fire of jealousy that simmered within him. Why do they deserve all that attention? Why are they so forward? What do they have that he doesn’t?

Despite himself, the young hero found himself holding you tighter, kissing you harder, doing his best to make sure to remind you (and himself) that the two of you belonged to one another.

When you finally expressed the discomfort you felt when talking to the other students, Kirishima wasn’t sure whether to be angry at them, or guilty for letting his jealousy blind him so much. 

Regardless, the two of you do come to a moment of admission where, maybe, perhaps, just a little bit, Kirishima was hot when he was jealous.
