Why?

Why the fuck am I doing this?! Liza shouted in her head as she knelt naked and still between the couch and the wall, with her forehead pressed against the wall and a lamp and a remote on her back.

Ever since she got home from her trip to the tattoo shop, she was doing everything her bitch stepsister Sydney was telling her to do. She had let Sydney film her stripping nude, then she barked like a dog, danced like a chicken, smacked her ass twenty times, then acted like and end table, and she could not refuse.

WHY CAN'T I STOP?!
