Young Spanish forced by her social tutor to fuck her like a prostitute

This young woman received a rented apartment to be able to live alone, because she can not support her mother, but has a social guardian who controls her. The man visits her from time to time to see how things are going and fucks her like she's a prostitute. He dominates her and forces her to throw some beastly dust, but her aunt has grown tired and has set up a hidden camera so everything can be recorded and the man can't have sex with her again. It is the last dust that lays it on and lasts a long time, because it had surely fucked its mother before.
