Not sure if this is the correct place to ask but here I go anyway:sneaky:.

I'm looking for I think was a 3 part series about a chubby guy moving in with a mother with 2 daughters. He goes after the youngest one first using some kind off plant hypnosis. After promising to leave her younger sister alone he promises to leave her alone if he can have her. But he sets the younger one up with her also hypnotized boyfriend. The mother is last.

Again this is all from recollection, the younger sister had blond hair, mother brown don't remember the color of the older sister.

Any help with the name would be greatly appreciated.
