A woman invites her friend over to her house, only to overpower her and transform her into a submissive slave. The new slave has no choice but to follow the dominatrix’s commands, starting with drinking her urine. The dominatrix urinates in her slave’s face and mouth, forcing her to swallow every drop. Next, the slave is positioned on her back and forced to feed on the dominatrix’s pussy, licking and devouring it despite her reluctance. The dominatrix becomes increasingly aggressive, smothering her slave in various ways. Eventually, she feels the urge to piss again and urinates directly into the slave’s mouth, leaving her no choice but to drink it all.
