I know you're a little nervous, but don't worry, this is a very normal procedure. We just need to collect a simple sperm sample, and you are in very capable hands. As your nurse, I will do whatever I need to for you to make sure we get the best sample we can. I'll gently encourage and instruct you on how to stroke, and even let you jerk to my sexy pink satin panties, spreading my stocking-clad legs wide so you can cum right on the crotch!
