Handjob Tease and Denial, Finally Mistress Restrains Masochist with Duct Tape While Dick Is Still Erect and Leaves Him

In a university where women hold power, men, whether teachers or students, cannot defy women. The female teacher changes into a leather outfit, strips the male teacher to his underwear, lays him on a desk, and restrains him with duct tape. She puts on rubber gloves, pulls his dick out of his underwear, and begins a meaningless handjob, grinning. She smiles as she watches his dick quickly become erect, giggling as she watches his face gradually become aroused. Her handjob is skillful, and just as man is about to climax, she lets go of his dick, edging it and smiling. Then she starts the handjob again, letting go just before he climaxes, preventing him from finishing. She giggles at man's tormented face as she plays with him, slowly, quickly, carefully, and roughly, alternating between teasing and denial. When man reaches his limit, she stops the handjob, smiles, and walks away. The man is unable to move, and if someone comes along, they will see his erect dick.
