Daddy's bet

Daughter  22 year old virgin. Still gives at home has a job and helps with bills

Daddy is in a group of incest lovers that meet each week. During one of these meetings the other guys make a vet with him. They bet he can't get his daughter to have a full blown affair with him behind his wife's back. Some of the conditions made at that he always has to cum inside her, the affair has to last for 6 months without being discovered, no birth control and he has to video each and every fuck. The daughter has a crush on her fit Daddy but hides it because she thinks he won't reciprocate. When She goes to tell her mother to get her mother out of the way he has to lock her in the basement. Telling his wife she's on a trip and won't be back for months. Coming down into the basement to take out his anger of the day and live out dark twisted fantasies on his daughter. All while she's pregnant. Can he find a way to get rid of his wife without her finding out about daughter's pregnancy? 

Things I want included: bondage, abuse, really rough sex (once she's in the basement), creampies
