His sister's sleep tee

The sun is getting low, amber rays gleaming through the many trees surrounding you in the middle of the woods. You pick out a pink tee shirt with the famous Japanese cartoon kitty on it, and slip it over your head and pull it down your still-damp body. Richard's sister's sleepshirt isn't as long on your frame as you thought it would be..

You shrug to yourself, it will soon be time to retire for the night, and tomorrow your things should be dry. You pull your long hair from under the tee's collar and start up the cabin's back stairs.

"Excuse me? Miss? Do you live here?"

You freeze in place.. one foot on the highest step. You can only imagine what you look like from behind..should you pretend you are the girl called upon?
