Chapter 4

The next day Jack received another call from the clinic. Would he be able to come in for another donation? He told them he would stop by the clinic after work.

After work he again found the non-descript building in the industrial park. He went in the front door and was again told to wait. He sat down in the waiting area and grabbed a magazine. He spent the next few minutes idly leafing through magazines while he waited.

After a few minutes of waiting Jack saw Karen come out of one of the doors down the hall. Jack stood up as the woman approached.

"Please come with me, Jack," she said and turned back toward the treatment rooms.

Jack followed Karen into the hallway and into the second door on the left side of the hall. The door closed itself behind them as the man and woman walked inside.

"Please remove your clothes and have a seat," Karen instructed, sitting down at the desk alongside one wall of the room.

Jack undressed and sat down on the paper covered treatment table. Karen spent a few minutes silently writing on her table and Jack waited patiently for her to finish. Finally Karen sat down her pen and swiveled her chair so she was facing Jack.

"Thank you for coming back to help us again today, Jack. Among the many programs we offer our clients we have several sex education courses. We offer training for girls and women who wish to wish to gain knowledge and skill in sexual activities. In the course of these training sessions we have a practical experience component. Would you like to help us with some of these sessions?" Karen asked.

"Sure! It sounds fun and interesting to me," Jack replied.

"Thank you for agreeing to help us. Today we have a client here who has been receiving training in giving fellatio. Today she is to have a practical session in sucking a man's penis until he reaches orgasm, accepting his ejaculation in her mouth, and then swallowing the semen. This is the session we would like you to help us with today." Karen told him.

"I would be happy to help you today," Jack said, already looking forward to having some fun.

"Good. All you have to do is allow our client to suck your cock and enjoy yourself. When you feel yourself getting ready to orgasm just let it come. Please don't say anything to our client during the session."

"OK," Jack agreed.

"Since I see you already have a good erection we can go in immediately. Please follow me," Karen said as she stood up.

Karen led the naked Jack out of the room and across the hall into another treatment room. Inside Jack found the same paper covered treatment table he had come to expect along with a small desk against the wall. Three women were already inside the room as Jack and Karen entered. One was Mei and there was a black woman about the same age as Mei dressed in the same style of skirt and blouse that Karen also wore. And the third woman must be the client for she was not dressed as the other two were.

The client was not dressed at all, she was nude. She was a small Asian girl with long, black hair. She was very young but not as young as she seemed to be for she had a thick patch of black pubic hair. Her breasts were small, only a slight swelling on her chest but her nipples were large and very dark. She was sitting on the edge of the treatment table and her eyes shot toward Jack as soon as she noticed him come through the door.

"Jack, you already know Mei and we also have Carol with us today. Our client as always must remain anonymous. Please move toward her until she can reach your penis easily. Let her do all the work, all you need to do is stand there and enjoy yourself. Please begin now." Karen instructed.

Jack walked over to the table and stopped with the head of his erect cock a few inches away from the young girl's face. Mei grabbed the remote control for the table and adjusted the high until the young girl sitting on it could reach Jack's cock with her mouth easily.

The girl was a virgin and in fact this was the first time she had seen a man naked or his penis. Now she was sitting naked with a cock just inches away from her face. She had received extensive instruction on what to do in this moment, now she had to actually do it.

Jack stood there silently waiting for the girl to make a move. She sat still for a couple minutes examining Jack's penis as it bobbed in front of her. She looked up at Jack's face for a moment, smiled shyly, and slowly reached up with her right hand to touch his cock. She brushed her fingers lightly along the shaft, avoiding the head at first. Then she ran her forefinger lightly around the head of Jack's penis, exploring the sensitive tip. The touch of her finger sent a thrill through Jack and his cock tightened and bobbed up in reflex to the girl's touch.

After exploring Jack's penis for a moment the girl wrapped her hand lightly around the shaft and began to slowly stroke it. The feel of her cool, soft palm as she stroked his cock felt wonderful to Jack as he stood there. He stood silently letting the girl do whatever she wanted and she was doing a very good job so far.

After stroking Jack's cock for a moment the girl stopped moving her hand but kept her hold upon it. The girl leaned forward and opened her mouth. She stuck out her tongue and gave the head of Jack's cock a light, tentative lick. This sent a thrill of pleasure from the head of Jack's cock to his brain and caused his cock to tighten. Emboldened the girl started to lick and explore the head of Jack's penis with her tongue. As part of her training the girl had practiced licking the head of a penis shaped dildo and she made use of her training on the head of Jack's cock.

The girl had to hold Jack's penis more firmly as her licking started to make it tighten and bob with each swipe of her tongue across the sensitive glans. After a moment more of this the girl stopped licking the head of Jack's penis and instead opened her mouth wide and took it into her mouth. She stopped there for a moment to get used to the cock filling her mouth and then she began to move.

The girl moved her face forward taking Jack's cock deeper into her mouth until her lips met her hand which still grasped it. Then she pulled back until only the glans was inside her mouth. As she bobbed her head the girl also flicked her tongue along the sensitive underside of the cock that was in her mouth. This felt wonderful to Jack and it was all he could do to resist the instinctive need to push forward into the girl's mouth. But he managed to do as he had been instructed and let the girl do all the work.

Despite her inexperience the girl was doing an excellent job of sucking Jack's cock and very soon she had him to the point of orgasm. Jack made no effort to resist it and he started to cum.

The girl felt the penis she was sucking tighten and the head swell slightly. Suddenly the cock bucked in her hand and she let out a surprised nasal "unnn" as a blast of hit semen jetted out of the head of Jack's cock and into her mouth. She made the same noise with each jet of sperm that jetted out of Jack's penis into her mouth. The girl valiantly accepted every spurt of hot cum that blasted into her mouth. For the first time the girl tasted a man's semen as he came in her mouth.
