ok so super weird but hang in with me,

It was a movie I saw when I was younger but that doesnt mean it was made in that time (aka it couldve been older) especially because it was on one of those free movie channels on direct tv.

the plot was it was this freak of a kid whose mom would kidnap girls for him because he had some weird thing about cutting them

he had like a room dedicated to clay versions of their body parts on the walls

then the mother kidnaps one girl for him and after a period of time she falls in love with him and the movie ends with them violently fucking eachother while slowly cutting body parts off eachother and bleeding to death
