Spanish young lady forced by her social tutor to fuck her like she was a whore

This young lady has been given a rental apartment so she can live alone independently because she can't stand her mother, but she has a social tutor who controls her. The man visits her from time to time to see how things are going and fuck her like she was a whore. He dominates her and forces her to throw some beastly dusts, but the aunt has already got tired and has put a hidden camera so that everything is recorded and so that the man can not fuck her again. It is the last dust that puts it in and lasts a long time because surely it has been fucking the mother before.
