Chapter 5

The next day was Saturday and soon after he got up Jack received another call from the clinic. Jack was asked if he would mind coming in to the clinic as soon as was convenient that morning. Since Jack didn't have any plans for the day he quickly agreed. They didn't go into any details about what he would be doing but Jack was sure it would be a very fun and interesting experience for him. Jack quickly dressed, ate a hasty breakfast, and was out the door on the way to the clinic.

After a few short minutes of driving Jack arrived at the office building which housed the clinic. He quickly pulled into a parking space, locked his car, and walked into the office. This was the first time Jack had been called in on a weekend so he was thinking this might be a longer session than he had experienced before.

Jack announced himself to the receptionist and was told he would have to wait a few minutes until they were ready for him. He sat down and picked up a magazine from the table next to his chair to help pass the time. Jack waited for about five minutes until he heard a door in the treatment room area open and a woman briskly walked out toward him down the short corridor.

Jack immediately recognized Mei walking toward him as he dropped the magazine back on the table and stood up. She was wearing a very short, tight mini-dress and as Mei drew closer Jack noticed her nipples pressing through the thin material.

"Welcome back, Jack!" the Asian woman said as she again greeted him enthusiastically. "I'm glad you could come today."

"Sure, I'm always happy to help here," Jack replied truthfully.

"I'm sure you are." The Asian girl replied with a knowing smile. "Please follow me."

Mei led Jack back to the same room she had just came from and he found himself once again in the same type of treatment room he had been in for his previous visits.

"Please remove your clothes and have a seat on the table," Mei instructed as she sat down in the rooms only chair. Jack quickly removed his clothes and sat down on the table and waited to see what would happen next. Mei spent a couple of minutes writing on the small desk in front of her and then swiveled her chair around so she was facing Jack.

"Jack, can you stay with us for the entire day today?" Mei asked. "We have several different activities today in which we would like you to participate if you are interested."

"Sure, I don't have any plans for today; I can stay for as long as you want me to." Jack replied.

"Great!" Mei exclaimed with a smile. "First we will need you to give us another donation just like the first time you were here. But this time we will be combining that with one of our educational classes so you will be our live model for the class. The class is male sexual function and the students are all young females. Would you like to help us with this, Jack?"

"Sure! It sounds like fun!" Jack replied.

"Thank you for agreeing to participate in our class. You will be providing much needed sperm for one of our clients as well as providing a big help in our education program at the same time. But it is very important during the class to not say anything or do anything other than what you are instructed to do. You've been very good with that up to now; will you be able to continue the same way?" Mei asked.

"Sure, I don't have any problem with that. Just tell me what you need me to do," Jack replied. "I'm ready whenever you are." During the short conversation Jack's penis had awakened and he was already sporting a firm erection. Mei did not fail to notice this as she was explaining what would be happening to Jack.

"Ok, then let's get started," Mei said, rising from her chair. "Please come with me."

Jack got up off the table and followed Mei out the door, his erect cock bobbing in front of him. He followed Mei further down the hall to a room that he had not been in before. Mei opened the door and held it open for Jack to enter and then followed behind him, closing the door behind her.

Inside Jack found a somewhat larger room than the ones he had been in previously but this one still contained the same paper covered examination table as the others. Also inside the room Jack found two more women who he already knew from his previous visits, Karen and Carol. In addition there were five younger girls who Jack assumed to be the students for this session. Karen silently indicated that Jack should take his place on the examination table which he did. Jack could feel the eyes of all the females in the room on his nakedness and especially on his hard, throbbing cock as he walked to the table.

"Our subject has arrived and everything is ready for our session to begin." Karen began who would be acting as the main instructor in the session. "In this session we will be demonstrating the male sexual function with the help of our volunteer here on the table. As you can see his penis is already fully erect which is to be expected from the situational stimulation he has been receiving. Please come closer so that you can all see clearly what is happening."

The five girls who were there to learn shyly moved closer to the table. The other two older women, Mei and Carol, gently chivvied them all up until they were standing right next to the table, with Karen on the opposite side. This allowed the five a clear view of Jack, his cock, and anything that might happen with it while at the same time Karen had plenty of room to do whatever she needed to do.

"As you can see our subject's penis has been circumcised which means the head is fully exposed at all times. Since he is already well aroused our subject will orgasm pretty quickly so you will need to pay close attention so you don't miss anything. When he does his semen will be captured for later insemination of one of our other clients." Karen continued.

"When orgasm occurs I will capture his semen using this special container," Karen told the group as she picked up and displayed the special glass container the clinic used for capturing semen. "You will notice the open end of the container has a wide flared opening which is large enough to receive the head of the penis when ejaculation occurs."

Karen reached down and gently took Jacks cock in her right hand. "As you know there are two very sensitive areas of the penis, the head and the frenulum on the underside." Karen touched both areas of Jack's cock as she lectured. The assembled girls could see his stiff penis jump with each touch. "You can see at the tip the urethral opening from which the semen is emitted upon ejaculation," the woman continued, gently squeezing the tip of Jack's penis to cause the slit to open.

"I will now begin to stimulate our subject's penis." Karen continued as she closed the fingers of her right hand around Jacks cock and began to slide her hand up and down. Jack's cock responded immediately to the added stimulation and Karen felt his cock stiffen even more in her hand. "Since our subject is already well aroused it will not be long before this added stimulation will cause him to reach orgasm. Carol, please hold the container and be ready to catch his semen. I think he will reach orgasm very soon," Karen said as she handed the container to the black woman.

All this was becoming too much for Jack and he could feel the orgasmic tensing starting in his cock and inside. He was getting ready to cum and it sure felt like it would be a strong one.

"I can tell by the way our subject's penis is tensing that his orgasm is imminent. Please watch closely and Carol get ready with the container!" Karen warned. Carol brought the open end of the container to the head of Jack's tensing cock and the watching girls leaned in for a closer view.

Just as soon as the black woman had the container securely over the end of Jack's cock his orgasm cut lose. The five young girls watched in awe as a strong jet of thick, white semen spurted from the end of Jack's cock, splashing against the end of the container. For Jack it was one of the strongest orgasms he'd had for a while and each new squirt of his semen into the container brought a new wave of pleasure. Karen's experienced hand milked his cock expertly, milking out as much sperm from Jack as she could which also just happened to give him the most pleasure.

"You can see our subject's semen is a sticky, thick white fluid that contains millions of sperm. Normally these would be ejaculated directly into a woman's vagina but some of our clients prefer artificial insemination. Carol will now leave and carry out that procedure while our subject's semen is still fresh." Karen said as Jacks orgasm faded and the last drops of his semen dripped into the container. Carol quickly capped the container and left the room, taking the container of Jack's semen with her.

The powerful orgasm left Jack spent for the moment and he just collapsed back onto the table. Mei bent down and quickly licked off the last drop of semen that clung to the tip of Jack's cock. Karen quickly ushered her five young female students out of the room leaving Jack and Mei alone for the moment. Jack was so spent from his orgasm that he actually fell asleep for a time laying there naked on the exam table. Mei worked quietly for a few minutes letting Jack rest to recover so that he would be ready for the next event they had planned for him.

Jack dozed on the table for quite some time until suddenly he was awakened by a soft hand gently shaking him. For a moment Jack was disoriented and couldn't figure out where he was then he opened his eyes and saw Mei just withdrawing her hand from his shoulder.

"Hello, did you have a nice nap?" Mei said with a smile.

"Yes I did," said Jack.

"Good," said Mei. "Are you ready for your next job?"

"Sure! What's next?" Jack answered.

"If you are rested enough we have a patient here for a natural insemination. It is the same one you inseminated previously; she is here for another session." Mei told him. "We have found that repeated inseminations by the same donor over a two week period are the most effective method for impregnation."

Mei's words sent a nice thrill down to Jack's cock and the Asian woman could see it responding already. She could still remember vividly the feel of that cock as it slid in and our of her own pussy and she smiled to herself knowing she would be feeling it there again later.

"I'm ready to get started whenever you are," Jack replied.

"Yes, I can see you are," Mei replied with a smile. "But remember this patient must remain anonymous and you are not to speak in her presence. Otherwise feel free to enjoy yourself as much as you want to."

"I remember that from before it won't be any problem at all," Jack told her.

"Would you like me to take my panties off before we go in, Jack?" Mei asked.

"Please do, that's a great idea!" Jack answered.

"Ok, off they come." Mei said as she slid her thong panties off and down her legs. She stepped out of them and then bent over to pick them up. As she did so her short skirt rode up giving Jack a clear view of her ass and shaved pussy as she did so. "All right let's go," Mei said as she set the discarded panties on the small desk and then turned for the door.

As the Asian girl headed for the door Jack got up off the table and followed her, his hard cock bobbing in front of him as he walked. Mei led him deeper down the corridor to another door on the same side. The woman opened and then held the door for Jack as he went inside and then followed him into the room.

Inside Jack found a treatment room of the same type as the others with the same table as the other rooms he had been in up to now. He recognized Karen and Carol standing beside the table upon which was the woman Jack would be inseminating. However unlike the previous session she was in a different position this time. Her head was still covered to hide her identity; but this time the woman was on her hands and knees with her ass up and open. This gave Jack an excellent view of her pussy and ass, both open to him very invitingly.

Karen walked up to Jack and reached down taking his cock in her hand. She stroked his penis a couple of times which sent a thrill of pleasure through Jack. "Jack, I can see you are ready to begin the insemination process so we will get started immediately." Karen said as she indicated the nude, kneeling woman on the table with the hand that was not holding Jack's penis. "Our patient has been prepared for insemination and is ready to receive your penis. I will guide your penis into her vaginal opening and after that please feel free to enjoy yourself until you reach orgasm. When you orgasm please try to ensure all of your semen is deposited completely inside her vagina. You may hold the patient's hips if you like but please do not speak while you are inseminating her," Karen instructed as she led Jack to the waiting woman.
