Keeping in line with protocol I have my mint green medical latex gloves on, and nurse uniform - as requested I do require you to provide me with a semen sample, however, I understand you’re having a little trouble ejaculating so I will offer some professional assistance.  I’ll use a combination of masturbation encouragement, teasing, dirty talk, and if that doesn’t work then you’ll have to watch me use my magic wand vibrator on my clit to get myself off in the hope that you’re able to provide me with your sample.
