Midoriya and Todoroki get hit by a quirk that triggers heats and ruts. In the 48hrs that follow, the secret that Midoriya has kept hidden is painfully revealed. Both Todoroki and Iida must find a way to keep him safe without hurting him further...and they'll need Bakugo's help.

Kirishima might not be first in the class but he's way smarter than to take Bakugou at his word about exactly what he's ready for during his next heat.

Sequel to '48hr Love Song.' In 48 hours things changed forever. Now Tenya finds himself on the road to an exciting future . . . if he can get past the maze of family politics threatening to trip him up. Things aren't easy when you carry a legacy like his, and your loves both have shadowed pasts choked with secrets. As for Ochako, she suddenly finds the road she's been on is actually a dead end. Lost and unsure of herself, she has to find a new direction to move in. Edit: Please notice updated tags

Obviously this was all the fault of Katsuki's perv classmate and his aerosolized heat trigger. Once Katsuki gets his life back under control, everyone will forget all about this moment of weakness. Nothing will change. He won't let it change. After all, he's going to be the number one hero one day. Just because omegas never go pro, that doesn't mean it isn't possible, right? ...right?

Kirishima tries to help Bakugou out during his first heat, and things get complicated.

"You wanna tell me what's fucking going on here, Half and Half, cause you look like shit and you smell even worse." Todoroki has been hiding his omega status for years, but one night his suppressants stop working. Fighting against the heat, Bakugou finds him and attempts to tell him off.

It's involuntary the way his knees seem to buckle and give out and throw him onto the ground. It takes him a moment to realize he's hyperventilating, tears running frustratingly down his cheeks as he rubs his clothed erection slowly against the carpet. / Or the one where Bakugou Katsuki is presenting as a fucking omega, and there's nothing he can do to stop it

Kirishima hates his luck. Not only is he a stupid Alpha, but his longtime crush is also an Alpha, (Except he's knot) AND he's the only guy in the world that has his ...problem. The fic where Kirishima has two knots but Bakugou is up to the challenge.

Toshinori's an omega, but he didn't choose it. He focuses on what he did choose - All Might - and endures the rest. A heat accidentally spent with Aizawa results in an embryo, some hard truths about the things he's been ignoring, and new hope.

Bakugou Katsuki is a camboy trying to make ends meet after he suddenly lost his job and most of his hearing. Touya's just looking for a good time.
