The black man who roasts Nadia Lapedra clearly has not been in a Russian prison and does not know what those domes that are stuffed on the girl’s chest and belly mean. If the guy had been given a proper licking in time, he would have been afraid to fuck such a thieves' authority (you could get raked for that). However, Nadya is not against it, which means that the hammering in the ochello is only for her benefit!
