A Lab coat and Mary's spare set of panties.

Nat walks in and discreetly closes the door behind her.

"Slim pickings, I have a spare lab coat from down the hall and, uhhm, something Mary left in the chnaging room." Nat blushes and offers up the coat and what appears to be a hot pink pair of panties with the word "needy" emblazoned across the ass.

"Oh. Oops. Ha. Uhm sorry, there wasn't anything else?" Mary squirms

"Wasn't really preparing to clothe a sex alien today when I packed my morning kit. Ya know? Didn't even bring my gym clothes."
