Last week Mrs. and Mr. Kuntz came to our sperm bank practice. His sperm was to be examined for quality because he wanted to register as a donor. Had super genes. So I took him to our little "practice wank room" with laptop as "aid". Here we already had some cocks in our hands. I told him to jerk off in the white cup so we could examine his sperm. Already after 2 minutes he calls for me! Oops, what's up? There's a laptop in the room for porn from the internet!!! Why call? He couldn't jerk off, let alone cum. Is this a trap for me? Should I watch him jerk off? Sometimes I listen at the door of the room and imagine the patient is holding his dick in his hand right now. Watching a porn movie and jerking his dick off! I wonder if he even thinks of me, the doctor's assistant. The fewest dare to call for me, because their wife is sitting in the waiting room :-) Good in the room wank and the faithful wife or girlfriend sits next door. What do you think what happened after he called me?
