Mirko's Secret Training Program

Mirko's all hot and bothered, but she got her eyes on a classmate. Her sharp eyes and bunny-in-heat instincts tell her he's packing some serious weight in his pants. After jumping him, she discovers his weakness: he really is packing, but it is a side effect of his quirk. And as he gets tired quickly, his quirk also deactivates quickly, shrinking him down to regular size. Not satisfied with this state of affairs, Mirko vows to give him a strict training regiment, aimed at raising his stamina. After all, she needs him to build endurance if she wants him to last more than one round with her~
