Chapter 1

Donna sat across the kitchen table from her step-brother, Todd. “What a nerd,” she thought to herself. “He wears glasses that look like coke bottles, reads computer magazines and prefers playing on-line games better than most anything else,” she thought.

Donna and Todd had become step-siblings five years ago when their parents married. Their birthdays were only a few days apart, so they had a lot in common. As much as Donna didn’t want to admit it, she was as much of a nerd as Todd. Maybe that’s why there had never been one minute of problems between the two of them from the day they moved under the same roof.

While Todd was a computer geek, Donna was just a scholar. With an IQ of 155, she was always the brightest person in her class and usually didn’t care for the company of her classmates. For her, they were just too young. At least, that’s how she saw it.

Todd was no hack when it came to intelligence. While he never mentioned it, his IQ was only three points lower than his step-sister. He had often wondered if that was why they got along so well. While other siblings seemed to always be arguing about something, he and Donna had never had a disagreement about anything other than things scientific.

“I’m a nerd, too,” she thought to herself. “How are the two of us ever going to get by in this world?”

At seventeen, both Donna and Todd were already in their second year of college. Because of their youth, their parents had decided that it would be best for them to live at home and be day students at the local university. Since both of them were shy, neither of them contested their parents’ decision.

Now with college level classes, neither of them had a regular schedule as they had in high school. As a result, they were quite often at home during the day while both parents worked. Todd’s father was the Chief Financial Officer of a mid-sized manufacturing company while Donna’s mother led a group of scientist at a local research laboratory. As the saying goes, the apple hadn’t fallen far from the tree. Due to the parents’ intellectual abilities, the children and adults got along famously. Todd began to admire and respect his step-mother almost immediately. Donna thought her step-father was simply the greatest guy in the world.

Life should have been a bowl of cherries, but this morning Donna’s mind was troubled. Sitting there, looking at her step-brother she wondered, “How will we ever get along in the real world? How will we ever find a perfect mate like our parents did?” Besides being exceptionally bright, her parents were very gregarious. They had a network of friends and were socially active. The children, on the other hand, didn’t have a single friend that they could call on the phone just to chat. Neither of them had a best friend.

This was a topic that had been on Donna’s mind for quite some time. She had decided that there was a solution to their problem and that it could be found analytically. Until this morning she had not mentioned her thoughts to anyone. But, today was going to be different.

“Have you ever had sex?” she asked Todd.

Looking up from the magazine he was reading, he stared at her blankly. “What?” he finally said.

“I didn’t stutter,” she said firmly. “I asked if you’ve ever had sex.”

“Sure,” he replied before turning back to his magazine.

“You are so full of shit!” she countered. “The only sex you’ve ever had was masturbation.”

Looking back at his step-sister, Todd smiled. “That’s still sex and you asked if I had ever had sex.”

Donna didn’t smile but appreciated her brother’s honesty. “How often do you masturbate?”

“Is there some reason that you want to discuss this topic at the breakfast table?” he replied.

Sitting up and leaning forward she answered, “I just want to know how often you masturbate.”

“Do you masturbate?” he asked.

Without even trying to think of a clever answer, Donna said, “Of course I do.”

“How often?” he said with a smile.

She had to smile because he had trapped her with her own question. “Probably once a day,” she told him rather proudly.

“Me too,” he said with a smile. “Now are there more questions?”

“I do have a few more,” she said as she stood and walked around to his side of the table. “Tell me why you masturbate.”

Thinking for only a few seconds he replied, “Because it feels good. What about you?”

“The same,” she said as she leaned against the table seemingly in thought. “I’ve heard mom and dad having sex at night. They seem to really enjoy it.” She paused a moment before looking at Todd and asking, “Do you think that we will ever enjoy sex with another person?”

“I certainly hope so,” Todd answered. “From what I read it is one of life’s greatest pleasures.”

“Exactly,” Donna announced as she stood again and walked around her brother. “Tell me something,” she said as she put her hand on his shoulder. “Would you ever take a test without studying beforehand?”

“No. Never,” he answered.

“So then, why would you have sex with another human being without preparing for it? Without training, what are the chances you would be successful?”

“What’s your point, sis?” he asked.

“It’s something I’ve been thinking about,” she said as she walked around the table. “You and I are both nerds. You’d admit that, right?”

Nodding his head, he answered, “We are.”

“So then, given that we admit that we’re nerds, what are the chances of either of us ever getting a chance to have sex with another person?”

“Since you put it that way,” he said with a frown, “The probability of a sexual encounter is probably not very high.”

“See,” she said with a smile. “You even sound like a nerd.” Walking to his side again, Donna put her hand on her brother’s shoulder and announced, “I’ve been thinking about this and I believe that we should help one another to be prepared for that eventuality.”

Todd might have a high IQ, but he wasn’t following his step-sister’s line of logic. “What?”

She pulled up a chair and sat beside him. “Look, the chances are better than average that we will have an opportunity to have sex with someone before we graduate from the university. I’m suggesting that we help each other prepare for that opportunity. Just consider it like studying for an exam.”

Todd stared at Donna for a long minute without speaking. “Are you suggesting that we have sex?”

“Well, maybe not right away,” she answered with a small grin.

“If anyone ever found out we would be ostracized,” he whispered as if someone might overhear them.

“First of all, no one would ever know unless you blabbed about it,” she told him. “Secondly, we are not really brother and sister. I am your step-sister and we are of no blood relation.”

“Still...” He said as he looked at her seriously.

Donna gave him a look to suggest he was being dopey. “We’re not going to rip off our clothes and have sex on the table,” she said with a frown. “I’m suggesting that we can help each other to prepare for the day when we are with someone else. You’ve only had sex on your own. You don’t know what a woman’s body looks like and feels like. I know nothing about a man’s body. Doesn’t it make sense that we at least practice a little?”

“That’s very logical,” he answered. “You’ve obviously given this some thought, so what’s your plan?”

She smiled sweetly, knowing that she had finally reached the coherent part of his thinking. What she said only made sense from a scientific point of view. “I’m suggesting that we get acquainted with each other’s bodies. You show me how yours works and I’ll show you mine.”

“You’re saying we should get naked together?” he asked.

“I don’t see any other way,” she countered.

“Again, that’s just logical,” he said. “Where?”

“My room or yours, it doesn’t matter,” she told him again demonstrating that she had already thought this out. “From my room, we would have longer to recover if mom or dad should come home unexpectedly.”

“Good point,” he nodded. “It should be your room. When do you want to begin?”

“What’s wrong with right now,” Donna said as she stood up wearing a bright smile. Hesitation is the precursor to failure.”

“Who said that?” he asked.

“Me,” she said with a grin and turned to walk to her room.

Once Donna and Todd were in her room, he started to close her door.

“Leave it open,” she told him. “It will make it easier for us to hear anyone in the house.”

“Right,” he answered and left the door fully open. Turning to face his step-sister, Todd asked, “How do we start?”

Dropping down on her bed, Donna answered, “I think we have to get naked and do some examination of each other’s bodies. I doubt that you know any more about a female body than I do about the male form. Right?”

Todd blushed. Her ideas were perfectly logical, but the idea of getting naked in front of her made him a bit uncomfortable. He stood quite still, staring at the floor.

“Oh, come over here,” she demanded. “I’ve seen you in your underwear. That’s almost naked.”

Donna got up on her knees on her bed and began to unbutton Todd’s shirt when he walked to the bed. “This isn’t going to hurt,” she said with a smile. “In fact, you might actually enjoy it.” Pulling his shirt off and tossing it on the bed, she looked up at him as she began to unbuckle his pants. When his pants dropped to his ankles, Donna looked down to see a rather large lump in his briefs.

She was certainly intrigued to discover what was creating the lump and considered grabbing through the fabric or pulling down his briefs to simply expose it. Deciding on the latter, Donna slipped her fingers into his waistband and made one swift downward pull.

“Oh my,” she said without looking at her step-brother’s face. “I had no idea you were this big.”

Her eyes staring at his cock seemed to add to the excitement in the room for Todd. He couldn’t stop what was happening as his cock grew to its full size and became rock hard. He felt embarrassment and elation at the same time. It seemed that the more she looked, the harder he became.

Finally able to speak, Todd said, “I’m not the only one that’s going to be naked. If we are going to explore each other, then you need to get your clothes off too.”

“Sure,” she said as she finally pulled her eyes away from his stiff shaft. Looking up into his face again, she said, “Do you want me to do it or would you rather undress me?” While he stood there thinking about it, Donna made the decision for him. “I think that you should undress me. You can consider it practice for when you actually have to do it for a real woman.”

Nodding his head in agreement, Todd lifted the sweater she was wearing over her head and looked down to see her wearing a not too sexy bra. However, it was the first time he’d seen a live person wearing only a bra and it seemed to stimulate him even more.

Still, on her knees, Donna turned around saying, “You need to know how to unhook a bra. See if you can figure it out.”

“Turn back around,” Todd laughed. “I think the trick is to learn how to do it without looking.”

Donna turned back to face him. “OK smart guy, give it a try.”

Reaching behind her with one hand, Todd managed to unhook both catches in under ten seconds. When Donna looked surprised he told her, “I read about how to do it in a men’s magazine.”

She was surprised at his agility but managed to turn the surprise on him when she let her bra slip off and fall onto the bed. As she sat up, Todd was as amazed at the size of her breasts as she had been at the size of his cock. They were round and firm, with hard pink nipples pointing at him. She was as aroused now as he was when his pants came off.
