The Nerds - Sex Education 301 And Graduation

The lesson plan attains its objective and Mastery is attained.


“We’ll see,” Donna had told Todd, but her mind was spinning.

Todd put his nose against hers and said again, “Tomorrow we are going to fuck. You can choose the position. You can decide if you want to do it in your bed or mine. You can choose if you want to do it in the afternoon when we are the only ones at home or at night after our parents are in bed. But tomorrow we are going to fuck.”

Donna lay there underneath him breathing rapidly. The truth was that she hadn’t really thought this union with her step-brother through. She had thought they could teach each other the basics of sex but never considered that he would want to actually have intercourse.

The idea began to grow on her. Who better to give her virginity to than the person she loved most in the world… her step-brother. She would never have to worry about him telling anyone. It was a secret that would be locked away forever.

As she felt his cock moving around the edges of her sex, she gave some thought to just doing it now but decided that it would be better if she had more time to consider how to do it.  “Okay,” she told him. “Tomorrow it is.”

“You aren’t going to back out on me?” he asked.

“No,” she answered as she ran the fingers of one of her hands through his hair. “I want it as much as you do, I think…”

“Good,” he said as he rolled over on his back. Within a matter of seconds, he was asleep.

Donna got out of his bed and returned to her room. As she closed her eyes to go to sleep she could taste her brother’s cum on her tongue. She smiled as she remembered what it had felt like when he had his orgasm. It’s going to be so much better when he cums inside my pussy, she thought as she went to sleep.

When Donna woke the next morning, she had a feeling of excitement in her stomach. Slipping her hand inside her panties, she found that she was already wet. The thought of what was supposed to happen today was as exciting as it was frightening. She knew that she shouldn’t be worried. Nothing was really going to happen that she hadn’t done before; except the part where a live person was having vaginal sex with her for the first time. She had put fingers, a vibrator and even a dildo inside her pussy before, but now she would be taking a real penis. And this real penis was pretty darned large.

As she brushed her teeth she was trying to decide what position she wanted to be in when she did it for the first time. She decided that she wanted it to be the missionary position so that she could see his face.  The next decision to be made was when.  Although she had enjoyed the dark sexiness of being in Todd’s bed last night with all of the lights out, she decided that the afternoon would be best. With just the two of them in the house, she could make noise without being worried about being overheard.

Donna felt like her decisions were made in a very mature way. She had considered all of the possibilities and made the choices that suited her best. She looked into the mirror. Her nipples were hard and showing through the light tee shirt she was wearing. Another check of her panties found them to be dripping wet. Looking at her reflection she smiled and thought, This time tomorrow I’ll be a woman.

When she went into the kitchen for breakfast, Todd was already seated at the table, as usual, with his face in a book. As soon as she sat down he looked over and mouthed the word “when”?

She whispered back, “This afternoon in my room.”

Todd smiled, pleased to know that she wasn’t going to try and weasel out of their deal. “I thought you might try to back out,” he whispered.

“No way,” she answered softly. “I have it planned out.”

“Yeah?” he said with a devilish smile. “What have you planned?”

“Never mind,” she answered with a blush. “You’ll find out when you get home from class. I expect you to be here by 2:00 and we’ll have at least two hours alone.”

Donna was certain that they were being discreet and that her parents had no idea what was going to happen.

Their mother looked over her shoulder and asked, “What are you two whispering about?”

“Uh… Nothing, mom,” Donna answered. “We were discussing the… the Homecoming Dance… and if we should go,” she blurted out.

Walking to the table, their mother said, “Really? Good! That brings me to something I wanted to talk to both of you about. Your dad and I were talking about it last night. We feel that both of you should be more socially active.”

“You were?” exclaimed Todd.

“Yes! We were. We decided that both of you need to undergo some changes so that you can improve your social acceptability.” She said in the tone she used when discussing her scientific experiments.

“Changes…? exclaimed Todd.

“Yes, young man. You need a makeover, so don’t make any plans for Saturday. Your father will be taking you to the ophthalmologist for contact lenses. It’s time to lose those coke bottle bottoms glasses you are wearing and for a decent haircut. As for you young lady…”

“Me!” shrieked Donna.

“Yes, you! You are coming with me.  I am going to take you to get your hair styled and to see about getting you some more alluring clothes than the sweats you seem to be married to. I also have an appointment to have your braces removed tomorrow afternoon.”

“I don’t mind getting the braces off, but new clothes? Is that necessary?”

“Yes!” her mother answered with a smile. "This Homecoming thing… do you have a date for it? Either of you?”

The kids looked at each other, shrugged their shoulders and admitted they didn’t.

“So that’s it. And no need for discussion. You need to change your look if you hope to attract a date.” She said as she turned and left the kitchen.

Donna smiled at Todd. “See, we started our training just in time. I think you are very cute, but I can just imagine you without the glasses and the hair, the girls are going to be all over you like crazy.”

“Well, I like the way you look," Todd smiled at her. “However, I can’t wait to see the new sexy you, and thank god for the braces.”

“Did I hurt you?" she asked.

“No! But I can imagine what it will feel like when you take it in your mouth without them. Mmmm!” he said, getting up and leaving the kitchen.

After breakfast, Donna collected her books and left for her classes knowing that she would be home at least an hour before Todd to get things ready for their big moment.



As she went about setting things up for their afternoon adventure, Donna suddenly began to wonder when she had lost control. She had decided to put a towel underneath them so that they didn’t leave stains on her bed sheets for her mother to find. Sitting on her bed with the towel in her hand she wondered, I was in complete control of this experiment. When did Todd begin making the decisions?

Had she actually been outsmarted by her brother? That just couldn’t be the case, she decided. But then, she had never known Todd to be as decisive as he was when he announced that they were going to fuck. Still sitting, she began to smile. She liked that Todd could be in charge. The idea appealed to her. He had always been rather like ‘milk-toast,’ but now he was showing some confidence. She liked it.

Just before 2:00, she heard the front door open and close. A few seconds later Todd walked into her bedroom. She glanced at his crotch and saw that he was already aroused. She smiled at him and patted her bed as a gesture for him to sit down.

Once he was seated she stood in front of him. “Here’s what’s going to happen,” she began. “I’m going to undress you and then you will undress me. After that, we’ll get in bed. I think that we should kiss and play with each other a bit. I don’t want you to just shove it in and be done.” She had been toying with the idea of holding him off for a while by giving him an orgasm before they had intercourse. Maybe that will put the control back in my hands, she thought.

“I’m good with that,” he told her. “I like that you decided to do this during the day. You have a really nice body, Donna and I like to see it. All of it.”

Donna blushed. “Thanks, Todd,” she said very softly. “I want to see you too.”

He stood and they faced each other. After what seemed like a very long delay, Donna reached over to her step-brother and began unbuttoning his shirt. When it was off, she pitched it onto a nearby chair. Turning back to him she put her palms flat on his chest. “You have a very nice chest,” she whispered. “I’ve noticed it before and thought it was sexy.”

Todd reached for her and quickly unbuttoned her blouse. He tossed it into the same chair with his shirt before making a motion for her to turn around. With her back to him, he unhooked her bra and let it drop to the floor. She hesitated only a few seconds before turning back to face him. “This! Is a sexy chest,” he said with a smile. His hands reached out for her breasts, touching them lightly.

“I like the way you touch me,” she told him as she watched his fingers move around her firm, round breasts. “I enjoy it when you touch my nipples.” She looked up into his eyes, saying, “I hope that you’ll want my nipples in your mouth.”

Now it was her turn. She stepped forward and unbuckled his jeans, gave them a push and watched them drop to the floor.  There was a fairly large wet spot on his boxers that was being pushed forward by his erection. Donna wanted to touch it but held back.

He did the same thing with her and that left them standing facing each other wearing nothing but their underwear. She was hoping that he couldn’t see the massive wet spot in the crotch of her panties.

“Together?” he asked.

“Sure,” she answered and they both pulled off the last remaining garment. They stood naked and admiring. He was studying her body and she seemed to be memorizing his.

“You’ve got a really nice body, sis,” he told her with his eyes fixed on her hardened nipples.

“For a geek, you look pretty good too,” she said, smiling. Turning around she asked, “Do you like my ass?”

“Oh yeah,” he answered with his voice cracking. “I’ve probably never told you, but you have a great ass.”

“You like it?”

“I really do,” he said as he stepped toward her and caressed her butt cheeks. “I’ve masturbated thinking about your ass.”

His hands came up and around her, cupping her breasts. As he lightly pinched her nipples he told her, “And I also masturbate thinking of your tits.” He pulled her back against his chest, letting his cock press against her back.

Deciding that now was the time to begin her delaying action; Donna turned, kissed his nipples and slowly dropped to her knees. In the bright sunlight of her bedroom, she could clearly see the precum oozing out of his big cock. As she'd done before, she ran her tongue under it, licking up all she could. Looking up at Todd with a wicked smile she told him, “This stuff makes a great lubricant, but I don’t think we’ll need any more than I already have.”

“Are you really excited?” he asked her.

“I’m trying my best not to scream,” she lied. “But I just need to taste you before you put this inside me.” Donna gave his cock a hard squeeze to make certain he understood what she was talking about. Looking ‘eye to eye’ with his stiff cock, she felt a strong desire to suck it in her mouth again just as she had done last night. But now she hoped to put on a better show for her partner.

Donna took the head of his cock into her mouth, swirling her tongue around it and savored the taste. It excited her as it had last night, but now she was beginning to feel her own juices running down the inside of her thighs.

She looked up at him. “You taste so good, Todd!” and began to bob back and forth on his shaft taking it deeper and deeper.  She looked up at him as her hand stroked his saliva covered cock. “I love your cock and I can’t wait for you to torture me with it.”

Donna took his cock back in her mouth, again moving hard and fast. She grabbed his balls and squeezed them, betting that doing so would push him right over the top. When he grabbed her by the hair and growled, she knew she had made the correct decision.

This was only the second time that she had taken his semen in her mouth, but she could tell that it was twice as much as it had been last night. As his cum filled her mouth and some ran down her chin, she understood that he had been excited all day.

Note to self, she thought. Be prepared for more than expected.

After he had emptied himself in his step-sister’s mouth, Todd fell back on her bed. “Holy shit,” he said as he flopped down.

Her fears gone and her decision made, Donna wanted to get closer to the main event.  She stretched out and patted the space beside her. As he moved closer, she patted herself between the legs, “I want you here.”

Todd stretched out beside her, again caressing her breast and running his thumb over her hardened nipple. Keeping her eyes locked on his, she moved his hand down between her legs, opening them so that he could touch her pussy.  By the time he touched her there she was so wet that one of his fingers disappeared into her.

He watched her eyes close and her mouth open in a quiet sigh. While he fingered her, Todd leaned over and sucked one of her nipples into his mouth.  As he pressed it between his teeth her quiet sign became a loud moan.  “Tell me you want this,” he whispered in her ear.

“Please, Todd,” she answered.  “I do.”

“Maybe while you are recovering, you’d like to kiss me right here,” she whispered as she touched her clit.

Without hesitation. Todd rolled right over and began to circle his tongue around her clit as he kept his fingers working inside her hot, wet pussy. In a matter of seconds, Donna was squirming and moaning, seemingly out of control. She forgot her plan to slow down the action as she reached her first climax.

It hit her like a strong slap to the face, almost making her lose her breath. She cried out as she pushed her fingers into her brother’s hair, holding him between her legs as if she never wanted him to move.

“Tell me how you want it,” Todd asked.

When she was finally calm again, Donna said to Todd in an urgent voice, “I want you on top of me. I want to feel your weight on me when you push your cock into me.”

Todd got up on his knees and adjusted her position so that she was in the center of the bed. He placed himself between her thighs and looked down at her lovely naked body. His cock was so hard it felt like a piece of steel. He lowered himself and ran the tip of his cock through her wet slit.  He could feel her trembling in anticipation.

He pulled her knees up and spread her open, seeing her juices sparkling in the light coming in through her window. He placed the head of his cock to her opening and pushed slowly, watching as the head disappeared into her virgin pussy.

“Oh, fuck,” she moaned.

“Do you want me to stop?” he asked.

“No Todd, please,” she answered. “I want it all the way in.  Please… now.”

He pressed again and his rod began to slither down her wet channel. Giving a strong thrust he felt his cock slide all the way into her hot depths. He felt the tip of his cock against her cervix.

 “You are so big,” she gasped. “I feel like I’m stretched to the limit.”

“Does it hurt?” he asked.

“No,” she said as she looked into his eyes. “It feels wonderful just like I knew it would."

He smiled at her and said, “Good.”

When he was fully inside her, he released her legs and put his chest against hers. He allowed her to adjust to the size of his cock before moving.

Donna’s pussy was very tight; he could feel her heat enfolding his cock, making it throb as he wrapped his arms around her.

He began slowly, withdrawing almost all the way before plunging back into her depths, because she was so wet, he slid in and out easily in her velvety sheath.

After several strokes, Donna wrapped her legs around him and locked them at her ankles. “Fuck me, Todd,” she begged. “I want it hard!”

Her instructions only aroused him more and he began to thrust faster and harder. He was so excited and she was so tight that he knew he wouldn’t last very long, but this felt so good he didn’t want it to end.

“That’s it… That’s what I want,” she said. “I knew it would feel this good. I love it!”

He could feel that he was quickly approaching his limit. “I’m going to finish soon,” he told her. “Where do you want me to cum?”

“In my pussy,” she answered as she panted, “I want to feel you cum inside me.”

“Are you sure?”

After, their lungs gasped for air. Their bodies were covered with sweat.

They remained quiet for several minutes, each of them replaying what had just happened in their minds. Finally, Donna said, “I thought it was wonderful. What about you?”

“It was great,” he answered with a smile. “It’s a lot better than jerking off.”

Donna giggled, causing her pussy to squeeze his cock. “It is a lot better than masturbation,” she said with another laugh. “How long will you stay hard?”

He had never considered that his cock could still be erect, but it certainly was.  “I don’t know,” he answered truthfully. “When I take care of myself it always gets soft right away.”

“Maybe it wants to keep going?”

She wrapped her arms around his neck and approached his lips with her tongue. Running her tongue over his lips she let it slide till their tongues were dueling.

“Are you happy that we’ve really done it? That’s we’ve had sex together?”


“You mean that?”

 “Well, put your hand on my cock,” Todd said as he pulled his cock out of her and pushed it up for her to touch.

“Oooh! It grew again,” she said as she wrapped her hand around his cock and stroked it.

“Ready for more?” he asked.

 “Fuck, yes,” she groaned when he started to move again. “I could do this all day.”

And they did… for the rest of the afternoon. They both had more orgasms than they could remember.

Finally, they stopped in utter exhaustion. They scrambled removing all traces of the lesson and had her room cleaned up and looking normal by the time their parents made it home.










Saturday each of them went for their makeovers with their respective parents. That evening on their return home they examined each other with curiosity during supper.

After supper, Todd led Donna outside.

“You look so different,” he said.

“So do you without those horrible glasses and with your hair not looking like Einstein’s. Now tell me why do I look different? It is the same me.”

"Donna, before you were cute, now you look so hot. I like the way your hair looks. Seeing you in a skirt and heels makes your legs and ass look fantastic. This isn’t a word I use very often, but damn, you are stunning!"

Blushing, Donna took his hand. “Todd, you are so sweet. I have to tell you that you now look like quite the hunk. I am sure the girls will be chasing you.”

“But I don’t want them chasing me. You are the only girl I need.”

“You have me, you know that, but if we don’t want to get busted by mum and dad, we are going to have to date others.”

”I guess so, but I will always want to be with you.”

“We’ll see. Just know that I have the same feelings for you, little brother,” Donna said as she led him back into the house.



For the next year, Donna and Todd had sex on an almost daily basis. They thoroughly enjoyed themselves and each day tried to find something new to try. Sometimes they would watch porn on her tablet and try to duplicate the action they had seen. They remained extremely careful and discreet, never taking a chance on being discovered.

Todd was particularly fond of coming home with some new position for them to try. Donna learned that if she was home first, she might as well get her clothes off and get ready. She soon found a robe that she liked and would remove everything before putting it on. Todd began calling it the “Ready Robe.” If she had it on, she was ready for sex.

The only time these two took a break was during Donna’s menstrual cycle. Because she was on the pill, her periods were not long, but Todd proved squeamish about blood. On those days, Donna was happy giving him a blowjob and making out with him.

That lasted until Todd decided they needed to try anal sex. Donna was hesitant, but, as always, let her intellectual side take over and guide her to the adventure of something new.

After the first attempt, they both determined that anal sex was something that they both enjoyed and practiced much more often than just on ‘period days'.

In her third year at the university, Donna met a very nice young man in one of her advanced chemistry classes. He was quite a bit older but seemed attracted to her at once. It took only two weeks for her to work herself into his bed.

In two weeks she was back home in her “ready robe".

“What happened,” Todd asked, ready to defend her honor if she had been taken advantage of by the older guy.

“Oh, he was a nice enough guy, but honestly… he couldn’t fuck his way out of a paper bag,” she answered, leaving her brother laughing.

As he laughed, Todd said, “He just didn’t have the sexual skills of your step-brother, huh?”

“No, he didn’t,” Donna answered as she began removing the robe. “And I’m in need right now.”

Todd, on the other hand, didn’t find a special woman until after he had finished his undergraduate work. It seemed that perhaps as a result of his broadened sexual horizon, he found that women around him became more interesting. During one week in his senior year, he bedded six different girls, with each of them telling him he was the most wonderful lover they had ever known.

After receiving their undergraduate degrees shortly before their twentieth birthdays, the step-siblings headed off in different directions for graduate school.  Donna headed to Northwestern for their wonderful science department and Todd headed to Georgia Tech.

While it was true that Todd wanted to expand on his degree in engineering and Tech had a great engineering department, in truth he was more lured by the siren’s call of beautiful southern women.

Graduate school ended their days and nights of sexual adventure. While they had easily earned degrees in their major courses at university, they had certainly reached a Master’s level in sex education in the bedroom.



On the occasion of their parents’ 35th wedding anniversary, Donna and Todd came home to share the moment with them. When the older folks had gone to bed, they sat at the breakfast table together as they had so many times as teens. Only now he was drinking scotch and she was having a martini.

“Does that husband of yours appreciate you?” Todd asked.

“Yes he does,” she answered with a sweet smile. “Jack thinks I am the sexiest woman alive. He’s always commenting that there isn’t anything sexual that I’m not willing to try.”

“Did you ever tell him that’s because you had already tried everything sexual with your step-brother?”

Stirring her drink with a finger, she looked seriously at Todd. “No, I didn’t think that was something he needed to know. I told him that I was promiscuous in high school.”

“How many times do you think we had sex while we lived here?” Todd asked.

Laughing, Dona answered, “I actually kept track of what we did and when, for a long time, but I’m guessing that while we were active together it must have been almost over a thousand times.”

“Have you had sex with your husband a thousand times?”

“No,” she answered flatly. “Robert’s a good guy and he loves me dearly, but he could never make me cum the way that you did.” She looked into her drink and said again, “Never.”

“Have you ever regretted what we did together?” he asked.

“Not once,” she said as she looked into his eyes. “You were the best sex partner a girl could have. I’ll be very honest. I’ve masturbated a thousand times thinking of the things we did in this house. I loved that big beautiful cock of yours and no one has ever fucked me like you did.”

The two sat there quietly sipping their drinks without speaking.

“You still have a great ass,” he said softly.

Donna drained her drink, sat the glass down on the table and said, “Do you think that cock of yours will still fit in my ass and make me beg for you to do it again?”

“Are your panties wet?” he asked.

“Oh yes. Are you hard?”

“Like a rock.”

“I want it,” she whispered with just the hint of a growl.
