A lesson for his son

Hmm... I should of put a noncon warning in, maybe, but it isn't really. It's the whole 'he says "don't do that," but then lets him do it anyway' type of thing. I guess some people could be offended by that? (But not all of the shouta incest?)

Enjoy.


A lesson for his son


---

One week into their training in the Hyperbolic Time Chamber, Goku realized that his son was behaving strangely.

Every time they took a break from their training, Gohan would run into the bathroom (he hadn’t expected the Chamber to have a bathroom, but had been proven wrong) and stay in there longer than Goku thought was strictly necessary. Even if the Saiyan armour was all in one piece and had to be completely removed, how long did it take to pee, anyway?

Then, just that evening, (in name only, since there as no way to tell) when they had been in the bath together, the boy hadn’t wanted to come out, even though they were finished and the water was cold. He had stayed in for five extra minutes, just sitting, whilst Goku dried himself off and prepared for bed.

So, now, with a false darkness created by drawing light-blocking drapes around the bed, Goku pondered. Maybe Gohan was sick, he thought. All sorts of strange things had happened to him when he hadn’t been feeling well, like the time he had thought he was a tree for three hours. Thinking was not really his strong suit and coming up with alternatives was too hard, so Goku decided that must be the problem.

He looked over at Gohan. They were sharing a bed that night because they had washed their stinky clothes before the bath, and they were currently drying on the other, which consequently meant they were sleeping naked, since both had realized too late that they had nothing else to put on. His son had been reluctant about that as well, it had taken some coaxing to convince him it was alright. The bed was just as big as the one he shared with his wife at home, after all.

In due time, Goku fell asleep. Shortly after, however, he was awakened by movement beside him in the bed. He glanced over again and Gohan, and saw (because it had been deemed too hot to sleep under the blankets) that he was not getting out of bed, as Goku had thought, but touching himself.

Ah. So that was what his problem was. Gohan was still asleep, at least mostly, and seemed to be unaware of what he was doing right in front of his father. He pulled on himself erratically, first slowly, then faster, and then slow again, and finally speeding up one last time, his other hand getting involved, and squirting cum all over his belly. A loud exhalation, and he rolled over and fell into a deeper sleep.

Goku considered this development. A few months back, Chi-Chi had informed him that it was high time he talked to their son about the ‘facts of life,’ whatever those were. Apparently, this was some sort of parental code for sex. She had proceeded to deliver to him a perfectly composed speech full of words he had never heard before: fallopian tubes, spermatozoa, ovaries, and so on, as well as passages full of the importance of responsibility and love. Goku had understood little of it, but had promised to remember it and impart this knowledge onto his son.

Only the opportunity had never really arisen, and he had sort of forgotten about it after a while. Well, now there was nothing to stop him from doing so. Tomorrow morning, he decided, they would have the talk.

---

Gohan was long in waking up. Goku sat for a full half-hour on the bed, waiting for him to rouse. When he finally did start to stir, it was another ten before he sat up, rubbing sleep from his eyes. “Good morning, sleepy.” Goku waved a hand at his son, who regarded him blearily.

“Morning, dad.” All at once, Gohan seemed to start awake. Hands flew to cover his dick, which was hard with the morning. A blush stained his face. “Uh…I have to go to the bathroom…”

“Hold on a minute, son. I want to talk to you about something important.”

“Can it wait a minute, dad? I just need…”

“Hey, don’t worry about it, Gohan. I understand.” As confusion creased the boy’s brow, Goku gently reached over and pulled his hands away from where they rested, revealing his stiff little pole to the air.

“Dad!” The blush deepened, and Gohan averted his eyes.

“Come on now, Gohan, did you think you were the only one this happened to?” Goku had purposely not dressed, and now indicated his own dick, which was hard as well. “Don’t worry about it.”

“Oh…well, okay.” And just like that, he stopped trying to hide himself, relaxing visibly and moving to sit in front of his father in the centre of the bed. It made Goku feel proud to know his son had that much trust in him.

“Now, listen. I’ll explain the facts of life to you, okay?”

“Okay.” He still seemed a little uncertain, possibly wondering what these mysterious ‘facts of life’ were, which Goku perfectly understood.

“Now, the first thing you need to know is…uh…well…” Somehow, in between the start and end of that sentence, he had forgotten the entire speech he was supposed to give. Not good. He did his best to remember. “So, let’s see…you’re a boy, so you have a penis, and it makes…uh…sperma…something. And then that goes inside a girl, and they go in some tubes, and…um…then there’s these eggs, and then they make a baby.”

His conclusion left Gohan looking as confused as he sounded. “Okay, I know that didn’t make any sense. Your mom’s going to be mad at me.” He sent a silent apology to his wife, and tried to decide what to do. There was no way to salvage his speech, so he decided to improvise. After all, he did know a fair bit about sex himself, so teaching it to his son shouldn’t be any harder than teaching him how to fight, right?

“Okay. The first thing you have to know about sex is that there’s two sets of rules.”

“There is?”

Goku nodded. “Oh yeah. One for when it’s a guy you’re with, and one for when it’s a girl.”

“Oh.” The boy really didn’t sound like he understood. “Why?”

“Well, because men and women are different.” The older explained. “You and me, we’ve got dicks, right?” He illustrated by poking the tip of his son’s lightly.

Gohan jumped. “Y-yeah.”

“Right. Well, girls like your mom and Bulma don’t.” Inwardly he was envious of his son for the education he was receiving. He had had to learn this all through trial and error. And getting hit a lot. “They have vaginas instead. So, we’re different.”

“Uh-huh. Okay.” His son was frowning, trying to sort his out in his mind.

“With me so far? Good. Firstly, you need to know what happens when you have sex. When you get married to a girl and have sex with her, she can get pregnant, and have a baby. It’s kind of complicated, but I think that basically, when you have do it, you cum—you know what that is, right?” At the shake of the boy’s head, Goku explained. “That’s what comes out when you finish jerking off—what you were doing last night. Gohan’s eyes went wide and he flushed again, but Goku continued. “I’ll explain that in a minute. But anyway, it goes in the girl, and then…something happens, and it turns into a baby.”

“I think I get it.” He didn’t sound like he did, but Goku didn’t have any more light to shed on the situation. At least the basics should be enough for now, even if he didn’t know the exact reasoning.

“Good. Now I’ll tell you about jerking off. I think you already know how to do that!” He joked, eliciting another blush. “That’s an important thing to know about, because it’s like having sex, only with yourself. ‘Cause you won’t always have someone to have sex with, right?”

“Uh…well, I guess so.”

“Okay, good. So, there’s some important things you need to know about jerking off. First, when you’re talking about it with a girl, it’s called masturbating.”

“Okay.”

“Okay, and second, after you get married to a girl, you’re not allowed to do it in the house. Girls don’t like it, see, so you have to go somewhere else.”

“But…why?” Goku didn’t think his son realized it, but he had grabbed himself during this explanation.

“I don’t know. That’s just what your mom told me. So, jerk off as much as you can before you get married. Trust me, you’ll miss it when you can’t do it anymore.”

“O-okay…”

“And last, sometimes you have to do it for other guys.”

“What! Really?” Clearly had not been expecting that one.

“Yep.” Goku nodded, trying to remember how Master Roshi had explained it to him that one time. “It’s sort of like an apology. You do it if you interrupt someone when they’re jerking off, or something else that’s important. It’s only fair.”

“Well, I guess that makes sense…sort off.” A worried look crossed his young face. “But…is it different to do it to someone else? I don’t really know if I could do it right…”

“It’s not that different.” Goku assured his son. “It takes a bit of getting used too, is all.” Gohan still seemed worried, so he continued. “I’ll teach you how, if you want.”

Gohan considered this, then quietly said, “Y-yeah…”

Jumping right in, Goku explained. “Well, it’s just like doing it to yourself, but sort of…backwards. You have too…um…” How to explain? Well, he decided, the best way to teach was through demonstration. You didn’t learn to throw a punch hearing about it. “How about I just show you?”

“Umm…I guess…”

“Okay…” Reaching out, Goku grabbed his son’s little dick. “Do what I do, okay?”

Gohan nodded, and reached out slowly to take his father in hand. “Good. Now, rub it like this…” He demonstrated, and Gohan cried out. He recovered swiftly and returned the favour. Goku shuddered at the pleasure running through him; it had been a while since he had felt another person’s hands on him.

He added his other hand into the mix, providing extra friction for his son. Just as Gohan did the same to him, the boy came, his cum splattering Goku’s hand. “S-sorry.” He managed, panting.

“You didn’t do anything wrong, Gohan.” Goku wiped his hand on the sheets and leaned back. “Now, you keep doing what I did.”

“Right.” A look of intense concentration settled onto Gohan’s face as he worked at his task, jerking his father off until he came as well, squirting cum up between them, covering both his belly and chest with it.

“Good job, son.” He reached out and ruffled black hair. “You have nothing to worry about. You did great.”

Gohan chuckled quietly. “Thanks, dad.”

“Okay.” Goku said, all business again. “So that’s all you need to know about jerking off, I guess. So, let’s see…what else…” He considered, deciding what he should explain next. “Alright, so next is sucking.”

“Sucking?” Gohan repeated, sounding like he didn’t really want it explained.

“Yep. That’s when you put another guy’s dick in your mouth, and, well, suck on it.”

“That sounds gross.”

“It’s not, look.” Goku scooped some of the cum running down his chest onto his finger, and without warning stuck it in his son’s mouth. “See? Tastes fine.”

Gohan made a face, but nodded. “I guess…”

“Good. Now, this is important to know, because guys who are friends do this all the time.”

“They do?”

“Yes, Gohan.” Goku nodded sagely. “It’s an important ritual of bonding, to symbolize your closeness with another guy. Krillin told me that when we weren’t much older than you.”

“Oh. I never knew that…”

“It’s not your fault. Nobody ever told you, right?” A nod, and he continued. “Now. There’s rules about who has to do the sucking. They kind of change a lot, but last I heard, it was whoever was younger out of the two.” He considered that for a minute. When he a Krillin had first started sucking each other, the rules had been that it was whoever was stronger. Then it had changed to whoever was taller, and then to the current rules, which had stuck around for a while. Goku wondered who made the rules, anyway, and how it was that his bald little friend always seemed to know them right away. It was a good thing he was so smart, he decided, or they both would have been lost. It was too bad that the rules had almost never let Krillin suck him, though…


“Oh, wow. I never knew it was so complicated.”

“Don’t worry about it, son. I’m here to help you. I’ll teach you everything you need to know. Here.” Goku crossed his legs and grabbed his dick, pointing it at Gohan. “Practice on me.”

“What? Suck your…”

“It’s okay. The best way to learn is from doing, right? You don’t want to get caught one day not knowing what you’re doing. Besides, we’re friends, right?”

“W-well yeah, but…Gohan was flushing to the roots of his hair. “I-I don’t really want to…”

“Sure you do. Here, I’ll show you first. It’s not gross at all, you’ll see.” Leaning forward, Goku grabbed his son’s belly and lifted him slightly, lowering his head until he came face to face with Gohan’s the little pole. He wasn’t slowed down by the organ, opening his mouth to allow it easy entrance.

“Dad!” Gohan shouted, nearly lifting off the bed. Of course, he had never felt anything like this before. “Daaad…”

Goku sucked for all he was worth, taking advantage of his son’s ten-year-old boy size to take the balls in his mouth as well, rolling them on his tongue as he worked.

Then he abandoned the balls, using his tongue instead to outline Gohan’s foreskin, until he slowly started to work his way under, pulling it back.

Gohan let out his loudest yell yet as he shot into his father’s mouth, then collapsed into a pile. Goku sucked a minute longer, making sure to get the last drop, then moved away and waited for him to recover.

When he finally opened his eyes, Goku said, “See? That felt good, right?” A heavy nod. “So, what’s the problem, then? Come on, don’t you want to know how to make other people feel like that?”

“Well…Uh…”

“Sure you do.” He grabbed Gohan under the armpits and hoisted him up, until his face was level with his father’s erection. “Come on, now. Suck on dad.”

Gohan’s mouth opened slightly, and Goku grabbed hold of himself and gently guided the pole to the entrance, filling one with the other. He only pushed the head in for now, Gohan was just starting, after all.

His son sat there for a moment as if unsure what to do, and then slowly started, just the lightest suck, tentative. “Good. Keep going, son.” He placed the hand that wasn’t on his dick on top of Gohan’s head, encouraging his head just slightly more downward. “See how much you can get in. Don’t try to put the whole thing in yet, just what can fit.” His shaft vanished incrementally into the boy’s mouth as he talked.

Just over halfway, Gohan gagged as too much dick tried to fit into not enough mouth. Goku pulled out long enough for him to stop coughing, and then guided his son back onto himself. “Don’t worry, it’s okay. Just keep that much in for now. Try using your tongue.”

He did, and even started sucking a little harder. He explored ever bit of Goku that was in his mouth, tracing the vein on the underside up its length, and then as far around the bottom of the head as he could go, and then finally up to the tip, licking lightly under the foreskin, the sensitive areas.

Goku felt his orgasm coming, and held if off for as long as possible, prolonging Gohan’s lesson. It wouldn’t do him any good to come now, when his son was just really getting into it.

However, he was only a man, and he eventually felt the undeniable tension. “Get ready, Gohan. I’m going to cum now.” He grunted, holding the young head in place as it tried to pull away.

Gohan tried valiantly to swallow as the first spurt shot into his mouth, and the second. Cum started leaking out the sides of his mouth at the third, and after that he started chocking, coughing seed all over Goku’s pelvis.

Finished, Goku released his son and let him get up. Cum covered his face, rolling down from his mouth. “Hmm…you’ll have to work on your swallowing. Look at the mess you made!” A laugh followed the joke, which Gohan shared feebly.

“Alright, son. You’re doing a good job. There’s only one more thing you have to learn.”

“There…there’s more?”

Goku nodded. “The most important thing. How to have sex with another guy.”

This declaration was met with little reaction from Gohan, just a bare nod.

“Okay. Here, come here for a sec so I can explain.”

He opened his legs so Gohan could sit between them, back pressed against his stomach, Goku’s now soft dick squished between them, one strong arm around the boy. His son was hard again, he saw, as he leaned them both back and drew his free hand down to his waist, lightly brushing it on the way to his destination.

“So, when you have sex with a girl, your dick goes in her vagina.” He placed the finger just under Gohan’s balls. “But guys don’t have vaginas, so when you have sex with a guy…” He let the finger drift down along the line of the boy’s perineum, right to the hole. “It goes in here.”

Gohan shifted uncomfortably as Goku rubbed the entrance. “In there?”

“Sure, look.” He removed the hand, quickly reached up and wiping some his cum from Gohan’s face before replacing it, using the now slick finger to gently penetrate the boy.

“Hey! Dad, what are you doing?” Gohan’s squirming increased; the rubbing helping Goku’s erection regrow to press against his back.

“Showing you, silly.” He allowed the finger to push in further, massaging the inside, trying to convince Gohan’s insides to ease up a little. “Come on, son, relax. Why are you so tense?”

“I want…you to take out…your finger. Please?”

“Does it hurt?”

“N-no, it just feels weird.”

“Don’t worry, you’ll get used to it. It feels real good, I promise.” The finger succeeded in getting all the way in, and Goku worked it around as best he could, at the same time probing the entrance with a second digit.

Gohan whimpered slightly when it passed inside him, but only said, “Dad?”

“Yes, son? What is it?”

“Are you going to have sex with me?”

“Yes I am, Gohan. I want you to learn properly, to make sure your first time is with someone who knows what he’s doing, so you know how to do it later.” Not like when he had learned at all, his first time that night with Yamcha. Neither of them had known about lube, about preparation; It had really hurt.

“I-I understand.” A great exhalation as Goku pushed the second finger all the way in. He kept them for a minute, letting Gohan get used to him, and then started spreading them a little, making more room inside his son for himself.

“That…hurts…” Gohan strained.

“I know, I’m sorry, Gohan. It’ll be okay in a minute, I promise.” He kept up the motion, and eventually Gohan stopped pushing against his other arm quite as hard. “Okay, I think you’re ready.”

“I don’t know, dad. I’m not really sure if I want…”

“Shhh, Gohan. Don’t worry.” He pulled the fingers our all at once and raised Gohan up, once again grabbing himself in one hand for better aim.

A quiet cry emanated from the boy as he was slowly sat down on his father’s dick, but Gohan gave no real protest. Goku was still nice and slippery from the mess his son had made earlier, so he slid in with relative ease almost the whole way.

Only when he was pushing the last quarter in did he meet with any resistance; Gohan suddenly would not go any further down. “Ow…dad…”

Well, Goku figured, no point in prolonging the pain. Best to get it all over with at once. “Gohan, this is going to hurt for a minute, but then it’ll go away, alright?” At his son’s nod, Goku pushed his waist upwards and his son down, and felt his hips connect with the boy’s.

Gohan let out a shout of pain and curled up around the arm supporting him. Goku waited until he felt his son’s breathing return to normal before asking, “Are you okay?”

“I…I think so. It doesn’t hurt as much anymore.”

“That’s good. Don’t worry, that was the hard part. You don’t have to do anything anymore. It’s all up to me, now.” He moved his guiding hand around Gohan and grabbed his dick again.

“O-okay, good.”

“Alright, just relax.” Goku thrust upwards, as much as he could with the position they were in. It would do for now, he guessed, starting a rhythm. Their motion was almost like when he used to bounce Gohan on his lap as a baby, he decided as he pushed into his son.

Suddenly, Gohan cried out again, this time in pleasure. “Told you it would feel good, didn’t I?” Goku asked, stopping his thrusting for a minute. Gohan nodded, and he continued: “That was your prostate I just hit.” He said, proud to have remembered that word from a doctor’s visit years ago. “I just call it the happy place.” He pushed and hit it again, getting much the same reaction.

Smiling, Goku continued hitting that spot, each time waiting for Gohan to recover before doing it again. Sure, he could just do it all at once, but he did want his son to enjoy himself as much as possible during his lesson. Besides, the longer it went, the more he would learn, right?

Soon, though, Gohan’s body had had enough. He seemed to convulse, and came again into his father’s hand. “Wow, Gohan. You must have really liked it. I’m not even finished yet!”

“S-s-sorry.” He panted, somehow sounding sheepish underneath breaths.

“It’s okay, don’t worry about it.” He thrust in again, and decided something. Best to teach him more than one position… “Here, I’m going to lay you down on your belly.” Staying buried inside Gohan, he did just that, kneeling overtop him. “There. Okay, are you ready for me to keep going? The sex can’t finish until the one inside the other cums, you know. It’s another rule.” Goku had never liked that rule, since it meant it could finish before the one on bottom did, but hey, rules were rules. They had to be followed.

“Yeah. You can keep going, dad. I’m okay.”

“Alrighty, then.” He pulled about halfway out, and pushed slowly back in. Gohan tolerated this well, so next time he pulled further out. Soon, he was going completely out and then back in every time.

Goku moved as slowly as he could, again wanting the experience to last as long as possible for Gohan’s sake. Although he must have been completely spent, his son seemed to enjoy himself some, at least, clutching at the sheets until they were ready to tear, his breathing growing more and more shallow as time passed.

He thought briefly of speeding up when he felt himself reaching climax, but decided against it. There would be other opportunities to introduce his son to differing styles, positions…they had a whole year in here, after all. For now, he stayed slow, his favourite way to do it.

Gohan’s body tensed up, and he lifted slightly from the bed, causing Goku to wonder if he had cum again. All thought of that was driven from his mind, however, when he finally started to finish himself, the first spurt of cum shooting out of him with surprising force.

Cumming inside his ten-year-old son’s butt was definitely the best orgasm Goku had ever had, it even probably topped the list of the best things he had ever done, even beating out winning the World Martial Arts Tournament all those years ago. It felt like he came with enough force for five people, and with enough volume. The last several spurts splashed out of the hole and leaked down the insides of Gohan’s thighs.

Finally empty, Goku pulled out and rolled onto his back beside his son. After a moment, Gohan crawled up and lay on his chest, and they cuddled for a minute. “Thanks, dad.”

“You’re welcome, Gohan. Here, I forgot one thing.”

“Huh? The boy lifted his head to look at his father. “There’s more?”

“Just this.” Goku leaned forward and kissed Gohan, pushing a little bit of tongue into his son’s mouth before breaking off and sitting both of them up. “Well, we should have breakfast. We’ve got a full day of training ahead of us.”

Both warriors climbed off the bed, not bothering to dress for the moment. Goku pulled great quantities of food from the refrigerator, preparing them for the breakfast they would need to get through the day. Piling food onto his plate, he said, “Now, I think we should go over that lesson again tonight, Gohan, just to make sure you got it all, okay?”

A choking sound raised his eyes from the table, and he saw Gohan coughing up his bacon. “What’s the matter?”

“N-nothing…” The flush on his face wasn’t just from the choking, he thought.

“Hey, no need to be embarrassed. Nobody expects you to remember everything after only one lesson. We’ve got plenty of time. We can go over it every night, if we need to.”

Watching Gohan’s eyes go wide with what he assumed was excitement at this thought, Goku was again envious of his son. Every boy should get to have this kind of education, he thought.

As, yes. I am going straight to Hell. But, all of you people are coming with me, at least. XD I was trying to go for an air of innocence around this whole thing; not sure if I quite pulled it off.

So...assuming anyone cares, the third chapter of 'To distract himself,' my overly wordy and adjective-leaden treatise on Cell, his offspring and their sex lives, was supposed to come next, but I've run into some trouble with it, namely that I don't particularly like it. I wrote it over Labour Day weekend, and have been editing and rewriting it since then. Never have I bothered to put so much work into one of these stories, but it's just so long and boring.

Anyway, If I decide to put it up, it'll be next weekend, I guess.
