I could not wait for them to leave as I had a throbbing erection. As soon as they left the room, I took out my penis and masturbated where I was standing with my still-lubricated hands. I, too, came in minutes, and as soon as my orgasm was over, I realized what I had done, the extent of the indiscretion—and how it would look if I was ever found out. I also realized that, in the way I handled that last sexual experience with them, I had made myself a necessary part of their sex. There was no way for them to repeat that experience together because they needed a third party to masturbate the both of them. I knew that what I had done was considered abuse from the point of view of my profession, but that the way I handled myself involved me much further with them, and almost guaranteed the situation’s recurrence.

When two days had passed, Julie and Andrew arrived as planned. They began the session by discussing their sex, saying that they wanted to know what more they could do to spice it up. Julie said that Andrew tried to imitate what I did with her clitoris the last time, but that his mouth never seemed to have the same effect. Andrew also asked if I could teach him how to use his mouth on his wife. Then he said that he wanted to know if there was anything else that Julie could do to please him. I answered that I would teach him, but Julie interrupted by saying that she wanted to learn first. I asked her what it was that she wanted to learn, and she replied, “You know, how to please a man.”

I said, “You mean perform fellatio?” but when I saw that she didn’t know what I meant I explained, “You know, give a blow job?”

She said, “I was always told that it’s not sanitary.”

“No,” I replied. “Not at all. It’s perfectly natural; I’ll teach you.”

I told Andrew to get undressed, and Julie followed the example, without being asked. Next I told her to begin by touching and rubbing Andrew’s penis with her hand until it got hard, then I would tell her how to use her mouth on it. Andrew got instantly excited, and his penis shot up to its full three inches in Julie’s hand.

“Now Julie,” I said, “get down on your knees so that you are eye level with his penis from where he’s sitting on the table. Then start by putting the head in your mouth.” As I was saying this, Julie was still stroking Andrew, and as soon as I mentioned putting it in her mouth, he shot off a little stream of cum that dribbled down Julie’s hand.

“Andrew!” shouted Julie, “now how am I going to practice?”
