A special dress

Amy, feeling sorry for her friend, rummaged through her bag looking for something, and pulled out a red dress "Here, I was saving it for tonight when I was going out clubbing, but I'll lend it to you willingly. God forbid I let you go around with your ass exposed!" she giggled.

Emily, almost moved, took that dress that separated her from total nudity and put it on without too many pretensions, only to then notice how tight and revealing it was: a sheath dress that barely covered Emily's ample breasts and ended with a skirt that didn't keep her vagina uncovered for two fingers. Emily tried to pull it as best she could, but wherever she pulled it revealed a bit too much, she decided to leave it so little covering "Amy, but it's scandalously short!!!" the recently dressed girl squeaked embarrassed "Hey, settle for it! This dress has earned me five free rounds of gin this month" she said shrugging her shoulders. Emily resigned herself, at least she wasn't completely naked now.

Will it be okay until the end of the class? Or will there be other unexpected events?
