I'm a nurse in a clinic that gets sperm samples. I notice that you're taking far too long to produce a sample. I ask if there is anything I can do to speed things along and then snap on exam gloves. I oil them up and start to jerk you off. I begin to dirty talk and say all sorts of naughty things and how much I love your cock. I decide it is better to collect your sample on my face! I wipe it up with my gloved hands and examine the specimen, even tasting it!
