Sex Machine (2005)

Director: Yuji Tajiri
Stars: Mutsuo Yoshioka, Rinako Hirasawa
What Five Minutes Were Like: This movie is properly titled. The two main characters just had sex to the point that they cause a minor earthquake in their apartment building. It's possible that the woman's son is downstairs, in what seems to be a restaurant (though one without customers). An older man is talking to the little boy about his mother having sex. This is complete nonsense. Good job, Sex Machine.
