Scene Four: Punishment

Starts in mid-action with Step-Dad and Step-Daughter struggling on couch. Step-Dad rips step-daughter's blouse open and panties down and slides his cock into her unenthusiastic wet cunt. With her hands bound he finishes fucking her, he grabs her by the throat, her eyes bug out, face turns red, she hits his arms and tries to pull them apart. He squeezes her cheeks, opens her mouth and fills it full of his seed.

Step-Daughter promises to never get bad grades again and is left in a sobbing ball on the floor...
