The prisoner got used to sucking cocks in prison to get small favors. This time he has to be grateful that his bucket was empty, so when he sees the dick in front of his face he opens his mouth and sucks it carefully. Then the man fucks him in a doggy position and after lubricating his asshole he fucks his asshole violently with his fist and then sucks the prisoner's dick with his fist in his asshole.
