You've come to the clinic to give a sperm donation but you're having some trouble with ejaculating. Your nurse checks on you and offers to help. As she strokes you with her gloved hands, she notices that you keep staring at her surgical mask. You confess to her that seeing beautiful women in masks is a kink of yours. After your confession, she knows just the thing that'll get you over the edge. Wearing her 3M respirator, she finishes you off--even letting you cum on the gas mask itself.
