Another sample

Dr. Jones took the sample cup from my hand, screwed a top on it, wrote a note on a sheet of labels, peeled a label off the sheet, and affixed it to the cup. "Well, that's the first sample. Now, we need more," she said in a low, sultry voice. "If you want a ten or fifteen minute break, that can be arranged. Would you like some water, soda or coffee?"

"Yeah, ten minutes should be enough. A Coke would be great," I replied. Seeing her beautiful tits and nipples was almost enough to get going right now, but, if I was going to be here for several more hours jacking off, I was going to have to pace myself.

The doctor closed her lab coat without putting her bra back on. Even through the fairly thick material, I could still see her erect nipples. The top of the lab coat revealed a lot of cleavage. She stepped out of the room. I sat down after pulling up my pants.

In a minute, she returned with a can and a cup of ice. I filled the cup and sipped it. "So, how is this process going to go from here? More sperm samples until I just can't anymore or pass out?"

"Basically. We are taking samples to measure the amount of ejaculate and the motility of the sperm cells of samples taken over a period of time. The time of each ejaculation is recorded, along with the type of stimulus used," she said while she removed her coat again. The sight of her tits and naked flesh got my soldier at attention again. I put the cup of soda down, stood up, and dropped my pants again, showing her I was ready for more.

"It would probably be most efficient if you just leave your pants and shorts off," she said as she started kneading her boobs again. I complied. I started wanking again.

After a minute or so, just watching her play with her breasts wasn't getting enough stimulation going, so I asked, "I need more. Can you masturbate for me?"
