Leave the bathroom door wide open...

Anna got the shower running and went to close the door, smirking to herself she instead opened it wider...then stepped into the shower, turning her back to the door as she started to wash the stress off of her body...after a minute or two she started humming something, to try and get Sams attention...

She smiled as she felt Sam step in behind her "Want me to get your back?" she asked slyly

"Why not get my front?" Anna chuckled, turning around and pressing her breasts against her friends.

And then they did the sex...the end...maybe...
