Basically blonde was having sex for the dad or professor then the son of the professor moved in and blonde found that guy more attractive so started having sex with him and both guys have feelings for blonde I think. Anyway then the dad/professor is suspicious so he plants cameras and sees them having sex and gets bad and calls blonder to the office building which is where we are now and the son walks in.
