Work Text:
Living with two mechanics was interesting. Aizawa was always covered in some form of grease or oil. At the end of everyday, Yamada would shove him into the bathroom and wouldn’t let Aizawa leave until he had showered thoroughly. The dark haired man would plead with his husband to not make him take a shower.
Of course, Yamada always won out. The man couldn’t stand being dirty. Why would he let his husband stay filthy? Yamada was a bit of a clean freak, but what didn’t bother him was cuts and bruises. The blonde would come home with his hands covered in tiny cuts. Some occasions he would have a rather large slash through his eyebrow that got rather swollen. He didn’t bother to care for them. Just as Yamada demanded his husband shower, Aizawa had to practically hold the man down to clean his wounds.
When Izuku joined the little family, they got better at caring for themselves. “Can’t set a bad example for the baby,” yamada would say. Something they forgot to take care of was Aizawa’s potty mouth. The man swore like a sailor every other breath when he was frustrated. He didn’t see the issue with it. That is until the incident.
Izuku had begged to sit in on Aizawa fixing a car in their garage. The boy wanted to learn how cars work from his dad. Being the softie that he is, Aizawa couldn’t tell him no. So here the boy sat. The dark haired man was under the hood checking everything. Making sure it had enough oil and power steering fluid.
That’s when the first one slipped out. Aizawa had pulled the dipstick out and “son of a bitch” was shouted so loud it made the boy jump. He grumbled a series of shits and dammits. Izuku hadn’t the foggiest notion what his daddy was saying. Maybe that was the name of what he was messing with. The older male started fiddling with something else when another pushed its way out. “Holy shit”. That one was just as loud. And on it went. The afternoon finally ended and Yamada had gotten home from buying the parts he needed.
“Hey sweetie what did you do today?” He questioned. “I watched daddy work!” The boy was so excited to tell his papa all he learned. He started telling him how daddy checked the son of a bitch and fixed the holy shit. He rambled for five minutes. His papa was wide eyed in horror. His sweet little boy was saying every cuss word in the book.
Aizawa who just got out of the shower had heard the loudest “Aizawa Shouta get the hell down here, now!” From his husband ever. His husband doesn’t cuss. He was in big trouble.
The man raced down the steps to see the blonde practically steaming from his ears. “Want to explain why our son just told me about your afternoon entirely in cuss words alone,”. Aizawa was dead. There was no surviving Hizashi’s rage. “Uhh,” what could he tell his husband to placate him. Yamada cuts him off, “you know what, I don’t care. You are gonna fix this and then you can sleep on the couch tonight,”. Yamada walked away and Aizawa deflated.
The blonde instituted a new concept a few days later. A swear jar. He saw it on some mommy blogger site. It said that the best way to cure a potty mouth was to force the swearer to pay a fine. Every time they cussed a quarter was donated to the jar. Aizawa lost a lot of his pocket change within the first week. Little Izuku had found it entertaining to watch his daddy add a new coin every five minutes. This was gonna be long uphill battle Yamada realized.
