When the poor slave is told by his two mistresses that he is allowed to come to the studio for an advanced fuck hole training session, he has no idea what the two devilish ladies have in mind. Whether mechanically, with a strapon or with a fist, the hole is torn open, stretched and fucked to the limit. Mercy is a foreign word in the ladies' vocabulary. In the end, he lies on the floor, anally destroyed and sexually used, knowing that he has the hottest fist and fuck of his miserable slave life.
