And, of course, a normal crush on the prettiest boy in class 1-A. Just like every teacher, right?

But when Shouto's father dies in a fight with a nomu, Aizawa suddenly struggles to understand the line between being a teacher, being a father, and being that guy who has wet dreams about the pretty boy.

Nemuri is there to help guide him, especially as they all settle into their new family dynamic.

Relationship(s): Aizawa/Mic; Shinsou/Deku; Aizawa & Izuku; Hitoshi & Eri; Izuku & Eri  

CW/TW: Mental health struggles, Underage NSFW, Omegaverse, Dub-con, Abuse of any kind, Any sort of discrimination (even if posed in a negative way), Brief mentions of past human experimentation; VERY mild Dubcon on both sides.  

SUMMARY: Shouta and Hizashi are a mated and married omega/alpha couple who already have two adoptive children – Hitoshi, a 16 year old alpha studying to be a hero in Shouta’s class, and Eri, seven years old and enjoying first grade, too young to present yet. After Hizashi’s involved in a human trafficking ring and experimentation case, he and Shouta find themselves fostering and rehabilitating the oldest victim of the operation, a 14 year old omega named Izuku. Izuku’s feral after the bust, his omega taking over to protect himself and the younger children and needs a safe place to come back to himself and recover.

Shouta and Hizashi are concerned because Izuku has reacted badly to male alphas and betas apart from Hizashi, who rescued him, because of Hitoshi. Hitoshi just wants to be able to help someone and try to be a hero to someone in need of one though, so he does his best to do as his fathers suggest, giving him time, understanding and space. It’s complicated and messy as Izuku acts more like a scared animal than human but slowly gets better with patience and care, especially from Shouta and his own more experienced (and maternal but he’s not going to admit that) omega.

And then Izuku’s heat hits unexpectedly when it’s only him and Hitoshi in the house and Hitoshi has to step up and help him through it even though he’s terrified. He is, after all, only 16 and has never had sex but Izuku, even though in his half lucidity says he doesn’t want to force him to do anything, is in pain and Hitoshi wants to be a hero. It helps Izuku finally break past his omega and feral state but leaves the omega feeling guilty and panicked. Thankfully Shouta is accepting and understanding and helps the younger omega to work through it. 

Relationship(s): Aizawa/Momo  

CW/TW: Mental health struggles, Underage NSFW, Minor/Adult relationship SFW, Minor/Adult relationship NSFW, Eating Disorders, child neglect  

SUMMARY: Before their final exams Aizawa is asked to personally tutor one his students. He is a little surprised to find that it is Momo Yaoyorozu, one of his top students. When he arrives at the lavish estate he is not surprised to see that she is alone. Despite how much they provide for her, the one thing her parents cannot buy is time and their work often keeps them too busy most of the time. A lot of people don't know how strongly Aizawa can relate to this lifestyle. Growing up with workaholic parents who supplemented their time and attention with fancy things has a dug a deep hole of resentment in him. So when he sees Momo in the same position he wants to do anything so that she does not have to suffer the same fates as him. He has seen the effects in class, that she is unsure of herself despite having excellent leadership potential. During these tutoring he will do what needs to so that she has the confidence to be the hero he knows she can be. Momo is more than appreciative of his time and when he starts to really applaud her and praise her she is starting to see him in a more intimate light.

CW/TW: Mental health struggles, Open/ambiguous ending, Any sort of discrimination (even if posed in a negative way)  

SUMMARY: It was hard for Shouta to let go.

He had no children. He told you that when you'd first met. Yet, you always found him very protective over his students. Over children that were not biologically his, but he still cared deeply about.

Kamino ruined him. He'd watched in horror as his students were assailed by All for One and saved by the ailing All Might.

He couldn't do anything to help them.

And you have to be there to pick up the pieces. 

Relationship(s): Aizawa/Mic; Aizawa & All Might

SUMMARY: On a late night mission, Mic is kidnapped by villains. He able to use his newest move “Golden Voice” to alert Aizawa who rescues him. They all go into hiding for a little bit. Against his better judgement and in order to protect Eri, Aizawa decides to take the Council’s offer of protection. However, in order to control Aizawa, like they have wanted to for years, they take Eri and threaten to poison her. As long as Aizawa obeys, they won’t. The only anticdote is tears from her mother. Everyone thinks Eri’s parents are dead, but the truth is, Aizawa is Eri’s birth mother (trans!Aizawa ftw). Aizawa is able to save Eri and take down the Council. Thus begins his vigilante era. 

Relationship(s): Aizawa Shouta/Midoriya Izuku will be the main focus, but possibly some Aizawa & Shinsou as well as Aizawa & Mic  

CW/TW: Mental health struggles, Suicide/Self Harm, Underage NSFW, Minor/Adult relationship NSFW, Dub-con, Weapons/violence, Abuse of any kind, Any sort of discrimination (even if posed in a negative way), Does quirk discrimination count as discrimination since that’s not a thing people actually face??? I know allegorically there’s a lot of similarities to ableism but idk. Also I selected dub-con cause underage relationship??? Everyone is fully consenting but also??? Minors can’t consent so… Just trying to cover all my bases!!  

SUMMARY: Shouta “adopts” a bordering on feral homeless vigilante who calls himself “Deku.” Izuku just wants to show Shouta how grateful he is to the one person who’s ever believed in him. 

Relationship(s): Main ship is Endeavor/Aizawa; with background Aizawa/Mic/Shirakumo  

CW/TW: Omegaverse, Dub-con, Dub-con due to a sex pollen-esque theme.

The mission itself went well up until Aizawa got hit with the full force of a pheromone quirk, making his Omega side go feral. Endeavor, wanting to help one of his comrades, whisked him away for his safety. Aizawa winds up begging Endeavor for his help--and his knot.

At least that was Aizawa's wildest sex story he had to offer his current partners. 

Relationship(s): Aizawa/Yamada; Aizawa & Eri  

CW/TW: Alcohol  

SUMMARY:  It’s festival time and Mic and Aizawa are taking Eri out to celebrate. Typical festival fare, they win her some prizes, enjoy some fireworks, and make sure she’s all tucked into bed.

A little night time fun ensues as Mic gets to show Aizawa just how much he likes his more nurturing side. 

Relationship(s): Aizawa Shouta/Shinsou Hitoshi; Aizawa Shouta & Eri; Shinsou Hitoshi & Eri  

CW/TW: Mental health struggles, Minor/Adult relationship SFW, Any sort of discrimination (even if posed in a negative way), Age Gap (NSFW), Religious Indoctrination  

SUMMARY: Aizawa can’t help but notice one of his students is displaying symptoms of stress beyond average. He’s always been attuned to his students, particularly this one who reminds him so much of himself.

He tells himself he won’t interfere unless it goes on for longer than two weeks.

His resolve breaks at a week and a half when they’re working together to set up mats for their martial arts club activities.

It’s not smooth or planned, and he very nearly mucks it up when he stumbles over his words, but by some miracle, Shinsou agrees to talk to him after club activities wrap for the day.

He’s not expecting the following conversation when Shinsou asks him if anything could make him stop loving his daughter. He’s not expecting to send his 16-year-old student home, knowing he is not alone.

And he’s certainly not expecting his student to show up to school weeks later with a duffle bag and a black eye.

—

It’s been years since Shinsou confided in Aizawa that afternoon in an empty classroom, and Aizawa feels weightless looking at his now-husband, peacefully asleep in his arms. He knows Hitoshi will wake up soon and takes the chance to start gently untangling his unruly bedhead.

When Shinsou does wake up, they reminisce together, enjoying a lazy Saturday spent in bed. 

Relationship(s): Aizawa/Touya

CW/TW: pseudo incest, adult/minor, alcohol, drunkenness, first times, feminization, masturbation, adoption, implied past child abuse, creampie, unsafe sex, boywife 

SUMMARY: Aizawa never pictured himself as a dad. He liked being alone, having his own space, and the peace and quiet. He didn't even plan on having a partner. Aizawa spent most nights staring at the bottom of a bottle, lounging on his couch and watching staticky TV. That type of life didn't mix well with any type of relationship. And he was okay with that. One night he runs out of beer and decides to head to the nearest market to get another pack or two. When he arrives, he's met with a scene he's witnessed all too often: some thug getting apprehended by the police. From what Aizawa heard, the thief was caught stealing bread. Aizawa scoots past them to purchase his usual beers when he hears the voice of a child slinging curses at the officers. The police were arresting a child. He couldn't have been older than 12, maybe 14. It was clear he was homeless. The poor kid was just stealing some bread to feed himself. In a state of panic, Aizawa stops the cops and convinces them to let him take responsibility for the kid. He'll foster him, get him on the right track, and make him swear not to cause anymore trouble. And now, after only a month, Aizawa's entire life has flipped upside down. He's responsibile for another person's life. A child's life. He doesn't even know where to begin. Lucky for him though, the kid is all too eager to get on Aizawa's good side. He cooks, cleans, checks in on Aizawa's well-being, goes to school, and does his homework. He's like the perfect kid. The perfect wife too, Aizawa has found himself saying to Touya many times. Poor Aizawa had no idea how personal Touya would take that statement.
