This AU, you are Deku. Female or Male doesn't matter.

It started on a mission. Bakugo was catching the villain who lured women. When the villain gets captured. The villain innocently asks, "What time is it?" You (Deku) replied, not thinking much, said 7:20. Bakugo looked back angry, "Why the fuck did you reply back-" Bakugo suddenly stopped talking.

Both of you felt a pang of pain shoot through you. The villain smiled as he had used his quirk on you guys and got away. Next day at dorms.

"Hey, Midoryia, do you have glue?" Kaminari asked. You nodded and went to go get it in your dorm room. But as you walked, you found yourself in front of Bakugo's dorm room. The door then opens to Bakugo about to leave for something but stops.

"The hell are you here for?" Bakugo asks. You explained that you needed glue for Kaminari. "Tch, I don't have that shit here." Bakugo said, annoyed. Awkwardly, you let out a chuckle, "I know, I was going to get it from my dorm. But oh, that reminds me, did you ever feel that pain back in the alleyway? When the villain asked for the time?" You asked curiously as Bakugo walks back in his room as you follow him in (you guys don't realize it). "Ha, yeah. Probably the villains' quirk." He sat on his bed, so did you. You couldn't help but think what the villains' quirk was.

But little did you know Bakugo was taking off his pants and boxers. You took off your pantswear, too. Suddenly, Bakugo was over you. Both of you froze. How did you both end up like this?

But what you guys didn't know was that the villains' quirk was luring. The villain had to do was ask what time it was, then ask if they wanted to come with him, which the quirk was ready in place when he asked for the time.

Right now, it was 7:20. And for about 10 minutes. You and Bakugo did intimacy. It always lasts 10 minutes. And every day before 7:20, but close enough, your guys' bodies move on its own to find each other, and when it hits 7:20, your bodies continue to move on it's own doing intimate activities.

It was now day three. Bakugo was in Deku's room. He had a scowl on his face as he listened to the idea you had. "What's the plan now, nerd?" He grumbled.
