Nurse Annisa has Elise Graves in the clinic and wants to see how much nipple she can take when she is under stress and how this affects her breathing. Nurse Annisa puts Elise in a black gas mask with lots of corrugated breathing tubing, leading to the rebreather bag and a squeeze to breathe ambu bag. This means Elise can only breathe when nurse gives her air into her bag. Lots of squirming and lots of noises coming from Elise. Just as well she is nicely restrained in the dentist chair.
