question about sex scene in general
in this film for instance they show the guy watching his mom getting boned from behind when he was kid .Obvioulsy you cant see and penetration but how do they get it so it looks like the girl is being penetrated ? it looks like the male actors pelvis is smacking up against the females ass cheeks because they are giggling .Does anyone know if his pelvis is really smacking against her backside or not ?
Humankind cannot bear very much reality
