An 18 year old young man has to become the guardian of his 14 year old step sister who has withdrawn from social life due to the shock of losing her parents. The young man uses hypnotism, exhibitionism and masturbation to turn the girl into a fun loving, happy girl.
Tired of watching his mother going to bed alone or worse with some random guy to fuck, he decides to be the man she needs - whether she likes it or not! Eventually he brings his sister into the family fold and becomes the man (and Master) of the house!
