Six months ago, in "Ass Goop Girls," Lilly revealed her fetish was to fuck in filthy sheets. So we had her and Kara Cox soak some sheets in the slop from their asses. Then we put the sheets in the freezer. Now, 6 months later, Lilly returned and we took the sheets out of the freezer. As the sheets thawed, Nurse Holl reamed open Lilly's ass with a massive strapon, making Lilly cry in pain. She also shoved her hand in Lilly's gape to open it up more. Finally, Dr. Mercies and Nurse Holl stuck a banana up Lilly's rectum, pounded it in deep, and then made her shoot it out into a bucket containing those nasty old sheets. We basically made even more slop for her sheets while Dr. Mercies slapped her face and ass. Dr. Mercies also poured some cum on her face--also from the freezer--and then he and the sadistic nurse dragged Lilly and her sheets into the padded cell so they could fuck her the way she always wanted.
