You're in for your yearly examination. I examine your testicles and the shaft of your penis before I perform the next portion of the examination procedure. I need to collect a semen sample for testing. It's procedure at this practice that I perform the extraction. Just lie back, this won't hurt you a bit. I put my gloves on and use my own saliva for lubrication before I start stroking your penis, unzipping my Nurse outfit to give you a bit of visual stimulation. I tell you how much I love cum and how it's a dream come true that I'm a professional Cum Collector. I stroke you until you ejaculate into my sample cup and I squeeze every last drop from you.
