Blackmailed by the nurse for being a pervert

It started as a simple exam at the clinic: the nurse gloves up, and then measures your pulse, checks your eyes, etc. Her perfume, her cleavage, her energy, her whole being is making you feel overwhelmed with desire.After a few minutes, she realizes that you are aroused, and she doesn't take this behavior very well. Angry, she grabs her phone, and before you can say or do anything, you are being recorded. Her smile gives you a hint: she will revenge on you and makes you do everything she wants to humiliate you.And since you got an erection, let's continue: she makes you jerk off in front of her phone, and gives you a countdown to cum.
