Zip the girl suit shut

As much as you'd like to try being the shopgirl, you zip the girl skin shut. Sure enough, the change from the ultimate costume back to the living girl it had been starts at once, and in maybe five minutes she coughs and sits up. "Don't tell me it actually worked!" she says, getting up with no difficulty from the floor.

"Okay, I won't tell you," you say. "Figure it out for yourself."

She looks at a clock with the Starship Enterpise logo on the dial, hanging across the room from the counter. "Hardly any time's gone by. I thought you'd try me on!"

"I can't just go around wearing hot girls as if they were cheap suits," you say.

"You're a gentleman," she says. "You know, if that brown pen thing works as well as the black one, this could be the perfect way to know if we're right for each other. Why don't you wear me for the rest of the day? Then I can wear you for a while. If we're right for each other, we'll know!"

"What if I put you on, use the brown pen, decide I want to be you, and stay you for life?"

She shrugs and looks adorable doing that. "It's a risk I'll take. Let's get naked, you zap me, you wear me, you get your inner woman with the brown pen, you put on your girl clothes and mind the shop. Tonight, tomorrow night, whenever, take me off and I'll try being you.
