"It was just a slip of the tongue ma'am, I really didn't mean anything by it!"
"Then we just need to make sure that sneaky tongue stays put then, yeah? I've got just the thing, don't worry." Whumper hummed as she finished restraining whumpee. She didn't even seem to be that mad, but whumpee knew better.
Not a moment later, whumper had pried open his mouth, and fit the sides with two metal braces. He bit down experimentally, but found they couldn't close their mouth if they wanted to.
" Now I know you didn't mean to say that, but the truth is that you did," Whumper called back as she rustled around in her toolbox. "So I'm going to do you a favor, and make sure that doesn't happen. That way, we can both be happy, yeah? I know what you really want is to obey, and that can't happen if we let little mistakes like this slip by."
Whumpee didn't reply, how could he? He shut his eyes, praying for whatever was about to happen to be over quickly.
"You want to do this eyes closed? Fine by me then."
Whumpee hardly had time to react as he felt his tongue being grabbed, pulled taut in his mouth. He tasted metal but...this wasn't quite like blood. His eyes snapped open, just a little too late. Whumper had an electric drill positioned in their mouth and a screw situated on the flat of their tongue. He hardly had any time to panic before the drill started up, driving a striking shock of pain through his mouth. Suddenly that metal taste started to become increasingly familiar, back to the blood he was used to. His screams only came out in gurgles as he tried desperately not to choke on his own blood. His tongue wriggled uselessly against the metal, but when the screw started to drill into the lower jawbone, he felt it grow still against his own volition.
Finally, when the drilling stopped, whumper took a few steps back to admire their work. Tears fell freely down the sides of whumpee's face, their aching jaw straining against the braces holding them open. Even whumpee knew he looked like a mess, only confirmed when he made out the satisfied smile of whumper through his watery eyes.
