Personal Trainer Vanessa Won't Apologize

Personal trainer Vanessa is training a client in a very arrogant way, being very dominant and arrogant to him. At some point, he has enough and jumps at her, clamping and handgagging her from behind. She fights back a lot, but she ultimately succumbs refusing to apologise to him for being so rude.
Scene fades back in showing her tied up, tapegagged and blindfolded, protesting soundly. The POV client is watching her squirm; later on he removes the blindfold and still demands for an apology, but Vanessa soundly refuses through the gag.

Suddenly there's a knock at the door: it's the next client, so Vanessa starts to squirm even more trying to be heard, but the crazy customer clamps and handgags her. The other client keeps knocking for a bit, but finally leaves thinking no one is in and the session is cancelled.
The customer leaves her alone, and she begins to desperately trying to break free or at least reach the phone... Before she can start a call, the customer comes back and stops her. Vanessa is left squirming on the floor.

Now Vanessa is poorly hogtied on a couch. The customer still demands for an apology, but she still fights back and visibly refuses.

Back in the gym, she stands tied up, tapegagged and handgagged by the client. Still lots of bratty fighting but no apology... After all, the client thinks, he got his revenge anyway. In fact, she has been kept for three days, she lost work, time and clients.
She gets ungagged, and, realizing that, she is furious at the client.
