This prompt is one I've been dying to play for a long time. The premise is this: you are the head of a Family Planning and Sexual Health clinic, Dr. Lisa Purnell. You and a professor from the local university have partnered up to lead a joint fertility study in college-age men ranging in age from 19-24. It's the goal of the study to gather reproductive specimens from a randomly selected group of applicants over the course of two weeks. During these two weeks, each patient will partake in a "sexual well-being" examination in which the physical traits, function, and production of healthy sperm will be recorded by a specially trained group of nursing staff organized by you, Dr. Purnell herself. Such testing will include dimensional measurement, an arousal evaluation test, artifical simulation, and most contraversial of all testing practices, natural stimulation. Your theory is that in age groups 19-24, the health, quantity, and delivery of sperm is correlative to the method and level of stimulation of the male member.

I'm looking for a woman who is capable of playing multiple roles seperately. The doctor, Lisa Purnell, is a more mature woman in her 40's with raven hair and an academic, albeit it slightly coy, interest in sex. Her nurse practitioners can be varied or similar, but all wear a similar set of teal scrubs meant to keep the wearer clean in the case of spillage. You can approach each test however you'd like, the nurses can be more professional and direct or a little playful. I'll be the anonymous test Donor 147. The artifical stimulation can be whatever method you think would be most interesting ranging from toys to purpose-built lab equipment. However, the natural stimulation will be administered by a nurse under the guidance of Dr. Purnell. One last thing, an amphetamine will be provided to the test subject in the form of a pill to greatly decrease the refractory period.

Donor 147 is slim and tanned, medium build, 5'11" with dusky blue eyes and thick, dirty blonde hair. He measures up just ahead of the pack at 6.2", but is notably thicker along the span of the shaft than other patients. Specimen is circumsised with no visible scar tissue.
