Part 2, last part.
After discovering his slave Killeru has hired an escort, Master Denny continues his punishment of the escort turned slave, Adonis, while his other slave, Killeru, cowers in the corner. Eventually, Master Denny brings Adonis in the other room putting him to sleep. He then takes Killeru back into the bedroom punishing him further. He then calls Adonis to come in and proceeds to make him jerk-off Killeru. After much humiliation Killeru never jerks-off and Master Denny frustrated and angry leaves both slaves for dead.
