Overhaul x Inflatee!Reader

Ch 1

"And who are you?" You looked up at the tall person in front of you, intimidated by him as he glared down at you.
"I'm (Y/N, L/N F/N)." You responded, trying to hide how you felt. Meeting people of his height wasn't something you did often, if not at all. He doesn't look too impressed with you, considering how you may have just snuck into his very well hidden base.
"And you're here for what reason?" You stared at him blankly. Why did you come here?
"I just wanted to, I guess." Shrugging, you responded with that. That only made him more annoyed.
"... So what you're saying, is that you came here for no reason?." You couldn't help but feel like he was going to get very annoyed, very quickly. Nodding you looked very worried. He sighed, turning away from you.
"Usually I'd be very annoyed, but maybe you could help me.." You couldn't help but notice the way his tone changed as he suggested this to you.
"How exactly can I help?" You asked, feeling a little suspicious of this stranger. He hadn't even told you his name, after all.
"There's no need to be so standoffish."
"It would help if I actually knew who you were."
"Ah yes, of course. Overhaul. That's what you are to call me." His beak-like mask moved the slightest as he spoke, making you want to call him 'Beaky'. It'd be a lot better than Overhaul, you thought, nodding at him so he knew you were listening.
"Now that you have a name, let me explain how you can help. I have a few incomplete versions of a drug I'm working on. I would like you to test them."
"Oh, so a Guinea Pig? No thanks."
"You don't exactly have a choice mx. It's this, or I kill you. And it'd be a shame to waste this opportunity."
Reluctantly, you agreed.
"Fine. But I want to be let free afterwards."
"That won't be a problem. Follow me.."
