Prison psycho Master Derek discovers his cellmate alone and naked and continues his vicious mistreatment. Desperate for a shit, the top smokes a fag and drops some steaming turds into a metal bucket, all the time degrading the runt. Rather than use toilet paper, Derek barks at the sub to lick clean his filthy arsehole before dumping the shit on the floor and ordering the worthless worm to eat up the whole bucket full.
