He is addressing the students, but his gaze is fixed on a particular student who is seated in the back of the room. The teacher's voice is low and commanding as he begins to lecture on the subject of BDSM. He asks the student to come forward and stand in front of the class. As the student obeys, the teacher begins to undress him, slowly revealing his muscular physique. He then proceeds to bind the student's wrists and ankles with rope, leaving him completely at the teacher's mercy. The teacher then proceeds with a series of spankings and rough handling, leaving the student moaning with pleasure and pain. The teacher continues to dominate the student, who is clearly enjoying every moment of it. The scene ends with the student completely submissive and at the teacher’s complete mercy.
