She slowly picks you up, pinching your clothes as you hover at her face. Your body swings around the wind at how far you are from the floor. Your a bit shaken up, fearing a bit you might drop dead any second.

Thankfully, this person switched, grabbing you with her full palm in a fist. But now comes a new problem, you couldn't move your body for a moment.

"Man, look how small you are. I could literally grab you like a Lego figure." She snickered, "Well, your still paying after all. Do you like, turned on by this kind of shit?"

Not really? You told her you were just fooling around with shrinking yourself. 

Her expression sours with confusion, "Huh, ok. But like, what now though? Do I just, shoved you in my pussy or what?"

That... Is an option, albeit a probably painful one.

Looking around a bit, you could see just how massive her cleavage is, That's another way you could have fun. 

But it'll be a bit boring, just standing around in a bathroom. Plus someone might come in here and barge in on you two. You could go back home or explore more of the mall now that your with someone.
