She wants to roleplay...

She hops up excitedly, "I know, let's roleplay!"
"Uh," you begin, not sure where this is going, "I havn't ever done that before. I don't think I would be any good at it."
"Nonsense," she reassures, "we just pick a common pair of personas, like a teacher and a student, and we dress up like them and pretend we are in those roles, and act accordingly and see what fun ensues!" She is already pulling you to your feet. You resign yourself, as you don't think you had a choice to begin with anyways.
She pulls you down the hallway, leading you by the dick. You are quickly aroused by the swaying ass in front of you; you suspect she is being slutty on purpose. She opens up her largest bag, and you find several costumes inside. First is a cheerleader outfit, complete with pompoms. She pulls out a schoolgirl outfit next. The skirt on that one looks way too small. Then there is a long skirt, like a businesswoman would wear, complete with a frilly top. Next is a simple spandex bodysuit. Then comes a slutty-looking number that a teen would wear, all lowrider jean shorts and lowcut top. After that a nurse uniform. Finally the last set is a security officer's uniform.
"Now, the only question is: which will you be?" She ponders a moment.
