Another two weeks went by before Zach was summoned to the exam room again. He stripped and was told to lie down on the exam table. He saw a large flat panel display hanging from the wall above his head, disjointed splotches playing across the screen. Alice Inou and another tech--she introduced herself as Mary Dexter--gloved up and rolled an equipment cart beside the table.
"Draw your knees to your chest," Dexter said. "We're going to insert this transducer into your rectum." Zach did as he was told and felt something slippery and cool press insistently against his anus.
"Bear down, please," Inou said as she pushed the transducer into him. Once it was in, she pushed it deeper then told him to lower his legs.
"Restraints," Doctor Cherinko said coming into the lab. Dexter and Inou draped seatbelt-like straps across his body and began fastening them in place.
"I'm not going anywhere," Zach said truthfully.
"We don't want you thrashing about and dislodging the transducers once they are in place," the doctor said.
When they were finished, Zach had a strap across his ankles, knees, stomach, and shoulders. Inou produced the seal cutters and removed his control device. Dexter held a long, black semi-flexible rod out for her colleague. It was tipped with a small metallic bulb and the opposite end terminated in a wire and a length of tubing. He watched as Inou ran a bead of lubricant along its length.
"What the fuck is that?" Zach cried.
"A transurethral ultrasound transducer," Doctor Cherinko said. "We're going to insert it inside of your penis and into the level of your prostate and seminal vesicles."
"It won't hurt, Zach," Inou said. "You did urinate immediately before your appointment as instructed, right?"
Zach was momentarily taken aback by the fact Alice Inou had used his first name. "Yes."
He was about to ask her if he could call her Alice when she seized his penis in one hand and stretched it straight out and angled it upward. She pushed the probe into the tip and he tensed as he felt it slide deeper and deeper.
"Oh shit!" Zach moaned. He felt the sudden burning urge to piss as the probe neared his bladder.
"Just relax," Inou said and pushed the probe farther. The burning became more intense and he thought he would die as the urge to piss became unbearable. Then, as soon as it started, he felt a give and the urge diminished.
"Ready?" Dexter asked. Inou nodded and Dexter handed her three fabric-like loops. Inou laid them across his stomach and picked up one at a time and coated the inside with the same clear jelly stuff they had used on him during the harvesting sessions. She encircled his scrotum with a finger and thumb and tugged his testicles down slightly. Mary Dexter picked up one of the loops then placed it around his scrotum and pulled it snugly and when Inou released him, he knew his balls were trapped by the loop. He had a disturbing flashback to the sight of Thomas, Peterson, and Sommers with their balls trapped by steel rings.
The two other rings went onto his penis, one at the base and the other encircling the corona. When finished, Dexter coordinated all of the wires and plugged them into the various boxes on the equipment cart. Inou began laying out sensors. She attached one under and below his left nipple, another above his navel, and yet another near his right nipple.
"The prototypes don't have integrated tumescence sensors, do they?" Inou asked Dexter who shook her head. Inou then attached a sensor halfway between the two loops on his penis on the top surface. He was beginning to get erect as she did this. Inou regarded her work a moment and gave Zach a slight smile then returned to her colleagues stripping off her gloves. He watched her plug the tubing from the transducer impaling his penis into another tube.
"The ultrasound won't hurt, Mr. Hill," Cherinko said. "As a matter of fact, we're doing it now." The pressure and burning in his groin had subsided by now. Other than the sensation of fullness, Zach didn't feel anything. He craned his neck backward. He didn't know what he was staring at but did notice that it moved in sync with any movement of his body. He clenched his groin muscles and saw the picture change as well.
"We've got good distension in his vesicles," the doctor remarked. "Two weeks, post-ejaculatory? Is that right?"
"Yes," Inou said.
To Mary Dexter, she said, "Are we recording now?"
"Yes, Doctor."
"We'll get our measurements when we're finished here but I can already see he's got quite a bit already by the distention we're seeing," Cherinko remarked. "Let's see the epididymides before we begin."
Alice Inou came back into view with a handheld transducer which she coated with more of the clear lube. She pressed it to his balls which would have immediately drawn up when the cold surface touched them had they not been trapped by the loop.
"Ah, yes. Marked distension there as well."
Mary Dexter added, "We get a very high percentage of sperm fractionates in his samples. You ought to see the numbers after distillation. Almost an ideal ratio. I wonder what we'd see after a month."
A month! Zach thought. "Hey guys?" he said warily from the table. "I don't think I can go a month without cumming if that's what you're thinking."
"Maybe after we bring the new system online," Doctor Cherinko said to Dexter ignoring his remark. "Then maybe we can consider doing a bit of pure research at that point."
"Ready?" Inou said, her hand poised over a button in the equipment rack.
"Yes," Doctor Cherinko said, her eyes never leaving the flat screen. "But I want to keep him at plateau longer than the last time."
Inou stabbed the button and Zach immediately felt the familiar tingling sensation in his cock. He began to respond immediately, his member swelling and lengthening. He watched with some interest as his erection appeared to climb up the probe within and engulf the exposed length.
"His arousal is more rapid than I expected," the doctor said.
"I believe that may be anticipatory arousal," Alice Inou said. "I'm sure you'd see it somewhat more delayed in inexperienced bulls."
