Genos / Saitama
Sensei's Crop Top @ AO3 by The_Button_Harlequin
Summary: Saitama finally looked up from his manga to give his disciple a mildly concerned look. “Dude, you okay?”
“Yes,” Genos heard himself say like it echoed from the back of his mind, “Are you aware of what you’re wearing?”
Saitama glanced down at his form and Genos couldn’t help himself from doing the same on a much more thorough scale. “Sweat pants? It’s what I always wear.”
“No, Sensei. I’m referring to the crop top.”
