Get Dad to cooperate

It wasn't the perfect scenario, but Bill had a plan. He sat up his newly transformed father in her armchair. She looked peaceful, but out of place in her old clothing. The thought of taking a peak under her shirt gave Bill a moment of hesitation that allowed his father to awake.

"What happened?" She asked, her voice was soft, but tone distinctly fatherly.

Bill cleared his throat, "There was an accident with the teleporter"

"Accident?!" Her eyes opened, looking down she saw her slim body beneath a business suit much too big for her. "What happened?"

"The teleporter got a crossed signal from my computer. And it's turned you into a girl."

With that she jumped from the armchair, rushing towards the mirror. "My face... I'm..." She begun to feel her breast through her shirt, she turned on Bill, "Why did you do this to me?!?!"

Bill took in a breath. Double down, he thought, you are already in this far. "Because I need a date for prom dad! Do you think I like looking like a piece of shit." Bill took all the resentment he felt and pushed it to the surface. His height much more intimidating to his now shorter father.

"But-"

"No, you don't! Don't act like you care! If you want to get turned back to normal you have to pretend to be my girlfriend. Otherwise I'll call the police right now. I wonder if they'll figure out your my dad transformed or some mentally disturbed woman who is trespassing?"

The woman stood there in shock.
