You have an appointment to see me due to your issues reaching orgasm and ejaculating. Good thing that is my specialty! I will need to collect a semen sample so we can figure out what is causing these issues. I am wearing a black surgical mask, and put on size small black nitrile gloves. I grab some lubrication and begin to glide my gloved hands up and down your penis, talking to you to help keep you relaxed. It seems to be helping and you're enjoying it very much so! Eventually, I notice that you have been staring at my surgical mask for awhile. You tell me that you love women in masks! You have been a great patient so far, so I decide to pull out a respirator mask and put in on. Seeing me in that mask pushes you to the edge and you're finally about to cum! As I'm stroking you and breathing heavily near your face, I give you permission to cum on my respirator mask. You have another appointment tomorrow, so we can collect an actual sample then ;)
