This can be an AU, Gakuen or Nations, I really don't mind.

I would like one (Or both) of them cross-dressing for the other. Focus on them getting ready, doing make-up, shaving body hair ect.

Smut is always appreciated =D.

Bonus - They go out while dressed up, for a meal, party or whatever.
Bonus - The other get very protective of them while they are dressed as a girl.
