1. Money has been tight ever since dad left and mom works two jobs, but still can't make ends meet.  Her son has a plan that just might fix their financial situation.  Mom will star in her own porn website which he can set up.  It may start off as soft-core but eventually the son will suggest they do some hardcore scenes with him as the male talent.

2. Mom does soft-core web-cam shows for extra cash and her son finds one of her videos by accident.  He then threatens to expose her if she doesn't become his personal fuck-toy.

3. Sister is having trouble with her homework, and asks brother for some help.  He agrees, but she has to become his slave for a whole week.

 4. Dad hires a hooker from a high-end agency, but when the girl shows up to the hotel it is his own daughter.
