Chapter 1

Jenny Bullock wondered not for the first time whether it was a good idea to have her son impregnate her. Not fuck her, of course, just impregnate her. None of this would be necessary if her husband would just admit that he had a low sperm count, she thought darkly to herself. No, it had to be her problem because she was old.

At thirty-four, she wasn't that old and most people would have guessed her for late twenties at most. Most people were shocked when she introduced them to Jules, her fully grown, six foot two son. He had just turned eighteen last month and even looked old for his age. More than once they had been mistaken for a couple, much to Jules endless amusement.

Now he was ready to move out of the house, and her desire for a baby had reached a fever pitch. She hadn't been on any birth control in years, but her belly refused to swell. Carl refused to pay for any medical help. He said that if it wouldn't happen naturally, it wasn't mean to be. Jenny was convinced that he was afraid that the doctors would determine that he was the problem, as if he weren't man enough to knock her up.

Carl thought much of his virility. He would tell the slightest acquaintance how he knocked her up at sixteen after the first time they fucked during his senior prom. It used to mortify her, but now it just seemed pathetic. What have you done for me lately, she would fume silently as his audience laughed and Carl beamed. Forget what you did in high school, she would think bitterly you're just shooting blanks now.

Most women in her position, would simply have an affair with the most attractive stud they could land. But Jenny was a housewife to a rich businessman hemmed in by servants at the house and an exclusive, but limited social circle that had no secrets. Carl was even getting paranoid in his old age. He might blame her for being infertile, but he didn't want to risk her being alone with another man.

It was almost funny at first. Especially, when he accused her of sleeping with her tennis pro, Pierre, who while handsome, big and strong, was so gay he set off most people's gaydar three blocks away. Carl was the butt of their friends' jokes for months after that. But as she considered her options in getting pregnant, it was looking less and less funny and more and more frustrating.

Two months ago, she broke down at an appointment with her gynecologist, Dr. Joyce Ceres. In between sobs, she told her doctor all her problems with conceiving. Jenny was surprised how easy it was to spill all her personal secrets, but it helped that Dr. Ceres was only a few years younger than her. She listened to Jenny without interruption, letting her talk out her problems and waiting for her crying to subside.

"So what you're saying Mrs. Bullock," said Dr. Ceres, "is that your husband refuses to admit that he might be the reason why you can't have a baby. He'll never agree to you going to a sperm donor and it would be too great a risk to have an affair."

Jenny just nodded and sniffled.

"So what you need is a man you can have sex with who looks like your husband but with whom you can associate without suspicion," said Dr. Ceres, "I have a suggestion..."

Jenny looked up, hopeful.

"Your son would fit both those qualifications."

To Jenny's horror, her first thought was not one of horror, but of agreement. It took a full half second for her inhibitions to kick in and spell out their objections.

"You're crazy," sputtered Jenny, "I can't have sex with my son!"

"Why not? Is he impotent?"

"No! Of course not. He's eighteen years old," said Jenny blushing as she remembered the bulge that she sometimes saw in her son's shorts. He certainly had his father beat. "That's not the point"

"Gay?"

"He's putting up a good front if he is with all the sluts that come to the house looking for him," said Jenny frowning. She didn't think any of them where remotely worthy of Jules. Of course, beautiful women often flocked to gay men, but from the look on those sluts faces, she was sure that they had gotten their claws into Jules and were looking for more. She blushed harder as she suppressed a surge of jealousy that was better left unexamined.

"Unattractive?"

"Hardly. Jules reminds me a lot of Carl when I first met him."

In fact, Jules was an improvement on his father. It wouldn't take much to outshine Carl now, Jenny thought to herself, with all the hair that he had lost and the weight that he had gained, but Carl was never an athlete. Jules lettered in track and had the body of a Greek god. No wonder he had to fight off all those sluts with a stick. If he fought them off at all. Once again, Jenny suppressed this line of thought.

"Well, Mrs. Bullock, you're son sounds ideal," concluded Dr. Ceres as if the matter was settled.

"You're making fun of me!"

"Not at all, Mrs. Bullock. Your son logically fits all the needed criteria to sire your baby."

"But, but, he's my son!"

Dr. Ceres patiently waited as if Jenny had not yet made a point.

"You make it sound like women get knocked up by their sons all the time!" yelled Jenny.

"Well, it is a bit rare," conceded Dr. Ceres in measured tones, "but hardly unprecedented. Many women today have children so late that they are menopausal by the time their male children have a chance to enter puberty. Of course, by having a son at such a young age that is not a problem for you. And, many women who have teenage sons are no longer attractive enough to sexually interest their sons. However, that is not the case with you."

Jenny didn't think she could blush harder but she did. She was actually quite proud of her looks. Her shoulder length black hair framed a face of sharp but very feminine features. She thought her green eyes were her best feature, but men rarely noticed them in favor of her 36D breasts. Gravity had taken a small toll on her breasts and the years had added a few pounds. No fashion model would envy her, but Jenny was not afraid to put on a bikini. Her husband actually had good cause to be paranoid.

"You're telling me that women have walked into this office and told you that they're pregnant with their son's baby," Jenny demanded skeptically.

"A few. Most don't. But when a women walks in pregnant after a gap of a decade, or more, and has long ceased to use any birth control, I have to wonder what the new factor is. Why should their husband suddenly be able to get them pregnant? Very often in such cases, there is a healthy teenage boy at home."

"It doesn't have to be her son," Jenny spat out, "It could be somebody from work or the paper boy."

"That is often the case, as well," conceded Dr. Ceres, "But consider how convenient a teenage son is for a woman in her thirties. The libido of a mature woman is an excellent match for that of a teenage boy. And a teenage son is so convenient. Once they discover that, a new baby in the family is an inevitable result."

Jenny couldn't believe that her trusted gynecologist was calmly discussing mothers getting knocked up by their sons as if it were a mildly interesting sociological trend. But the notion of middle aged woman having hot passionate sex with their teenage sons, all afternoon no doubt, while the father was at work was sending her imagination in uncomfortable new directions. She firmly suppressed a mental image of Jules on top of her, pumping away, and then cumming into her wet pussy. What was really disturbing was how little it actually disturbed her.

"I am not having sex with my son. That is final. It would not be good for him, or me."

"Sex is very medically beneficial."

"Jules is getting all the sex he needs from the sluts he meets at school. And I'm..." And I'm only getting it three times a month at best, she completed in her thoughts. She once again firmly put away the image of Jules on top of her, all afternoon long.

"And... and I'm not going to have sex with my son!" Jenny finished lamely.

"Well, we could just use his sperm to inseminate you."

Jenny was silent as conflicting thoughts went through her head. As Dr. Ceres had hoped, the idea of being inseminated by her son's sperm seemed almost reasonable when the notion of fucking him was introduced first.

"Couldn't we use somebody else's sperm?"

"Only if you could think of somebody who was as likely to keep it a secret."

The truth was that Jennifer wasn't sure that Jules would keep it a secret. He and his father did not get along, and him impregnating his father's wife might be too juicy a secret for him to keep. On the other hand, Jules intended to move out soon, and he would keep quiet to make life easier for her.

"Do you think Jules would agree to do it?" asked Jenny. Actually, she thought he might be a little too enthusiastic about it. Would he ever think of his mother the same way knowing that his child was growing inside her?

"Better let me do the asking, Mrs. Bullock," said Dr. Ceres to Jenny's relief. "I'll schedule you for a follow up appointment for next week, and you can bring him along so that I can test his sperm count. Let me also give you a female condom that you can use to collect a sperm sample from your husband."

Jenny hopped down from the table feeling slightly better. As she exited, Dr. Ceres handed her a bottle and a female condom. Jenny accepted them dubiously.

"Just wear this during normal intercourse, Mrs. Bullock. With the lubricant he shouldn't notice any difference, unless of course he engages in oral stimulation on you during foreplay," explained Dr. Ceres professionally.
