You were heading toward the Support Course Department to fix your hero costume after it been hit hard by Todoroki, Bakugo and Midoriya. But Hatsume was an excellent inventor who could fix the most damaged pieces of armour into something that could go for big money. You knocked on the metal large door, though all you can hear was the sound of machines. You knocked again, no reply. So you peaked your head in and you were in shock. You find Hatsume yes testing her inventions...but for sex?? She was jerking her futanari penis to the Pro Hero Mirko...wait she's hear too?? She was sat completely naked on a metal lourde, and a pink silicone sort of claw gripping her balls as she jerking off with her prosthetic metal arm rapidly. Hatsume: S-So h-how do you like my babies?? She asked with panting giggle and a crazed stare as she jerked off quicker. She had a small remote device and she seemed to turning on the level to whatever this machine was. Mirko: Hhaaah...f-feels pretty good. Y-Your a damn good inventor." She said with a tiny bit of blush on her face which was rare. She looked like she was going to break. Her other prosthetic arm was gripping the handle of the heavy hourde tightly.
