Over the next 15 minutes, the group compiled a list of what humans and Saiyans (more specifically Bulma and Vegeta) enjoyed or could potentially be influenced by.
Chi Chi dominated making the list on Bulma's behalf. The items included: technology, inventing, strawberries, chocolate, bad boys, vehicles, adventure, dragon balls, fashion, her hair, Yamcha, shopping, alcohol, underwear, cats, time machines, and the Capsule Corporation logo.
Piccolo and Goku were able to come up with: fighting and "maybe food" for Vegeta. Chi Chi added: "universal domination," "killing my husband," and "knocking up Bulma, apparently," to even out the two lists.
The team stopped to take a dinner break, putting their discussion on hold as Gohan was in the room. The Son family ate as the Namekian sat quietly with a glass of water. Despite Mr. Piccolo's lack of participation in their evening conversation, Gohan was thrilled to have him present for a reason the warrior didn't fully understand. When their meal was finished, Gohan was sent to get ready for bed as the trio continued their project from earlier.
"Sooo… what exactly do we do with this list?" Goku asked as Chi Chi played with the pen in her hands, deep in thought.
"Well before we can do anything about it… I kind of have a concern." Chi Chi paused, suddenly blushing a furious red, "do you think he knows anything about… you know?"
Piccolo and Goku stared back at her blankly, clearly not knowing.
"You know… about doing it."
The following silence encouraged Goku to take a guess at what the woman was trying to convey, "Um… does he know about doing the Kamehameha?"
"No! About sex, Goku! Not the Kamehameha!" the human huffed and crossed her arms, "I mean, you were clueless about that stuff until our wedding night when I had to give you a quick rundown on how things worked- and you've been on Earth for decades!" she sighed, shaking her head, "think about it- from my understanding he lived out in space thinking only two other males from his species were what was left. He might never have learned about that kind of thing… or maybe he's all confused after interacting with so many different aliens his whole life…"
The Saiyan pondered that information for a moment before turning to Piccolo, "What do you know about that kind of stuff?
"Uh…" the Namekian blushed, "…well I came out of an egg… so…"
A chair scraped along the ground as Chi Chi quickly stood up and marched towards an overstuffed bookcase lining one of the walls of the Son household. After browsing the selection, she pulled a textbook from the wall and slammed it down on the table.
"Okay, here's what we're going to do. I'm going to have a much needed biology lesson with you, Goku- Piccolo, you should hear this too- and then you're going to practice by giving the talk to Gohan. He's mature for his age so we should be having these discussions anyway."
"But I didn't learn about it until I was an adult!"
"Goku you're a… special case." Goku smiled at that and the housewife opened the book to a page showing the more intimate parts of the human body in complete detail.
"So there is an egg involved- but it doesn't come out of your mouth."
"That is correct, Piccolo. When the sperm from a male fuses with the egg it forms what eventually becomes another human. Or half-human, in our case…"
"Piccolo, you fused with someone on Namek, right? Chi Chi is that kinda the same thing?!"
"No Goku, Namekian fusion is not similar to human reproduction… I don't think."
Explaining sex education to two aliens was as bizarre of an experience as one could imagine. Eventually, the housewife felt that her two students were ready to become educators and went to retrieve Gohan from his room.
Goku and Piccolo waited nervously as Chi Chi brought Gohan out, hair disheveled and rubbing the tired from his eyes. He sat at the table, looking around both confused and drowsy.
Chi Chi and Piccolo looked at Goku expectantly, waiting for him to start. The Saiyan cleared his throat and began the lesson.
"Hey son… so um, we have something important we need to talk about… your mother and I think you're old enough to hear about this now… well mostly your mom told me you were…" he nervously glanced at his wife, who gave him a thumbs up, encouraging him to keep going, "Gohan, what do you know about… sex?"
Gohan stared at his father, unable to keep the fatigue from his eyes, then glanced at the table now covered in books, crude drawings, and diagrams. The half-Saiyan looked around the room.
"Mom, dad, I've already read about this stuff like forever ago. I don't think I need a lesson on it and I'm really tired so I'm going back to bed now." He hopped down from his seat and left the room, the rest of the company staring at him in shock. Apparently a sleepy Gohan was not the polite young boy he typically was.
Goku grinned, leaning back in his chair, "I don't know what you were complaining about, Chi Chi- that was easy. Maybe I should be Gohan's new teacher!"
All confidence drained from the Saiyan as he looked over at his wife, whose eyebrow was twitching in rage and whose face looked less than amused.
"Kakarot, you better have a good reason for bringing me out here again."
They landed in their typical sparring area located at the same clearing in the same forest, only this time Piccolo was awaiting their arrival. He acknowledged the two Saiyans with a glare as they landed in front of him.
Vegeta smirked, "Don't see the point in bringing the Namekian, though. As if he could keep up with two Saiyans."
Piccolo scowled at the smug prince, "If I too got a power boost every time you failed to defeat an opponent, I would at least be a Super Saiyan by now."
Responding with a growl, Vegeta opened his mouth to no doubt berate the other warrior, but Goku stepped in between the two before matters got out of hand, "Okay, you two. Let's save the fighting for the androids!" he grinned sheepishly at the older Saiyan, "-but first we need to have a talk about something."
Vegeta raised a brow at the odd behavior of the other man, but followed him anyway when he began to walk away. Goku picked up a textbook from the ground and sat on a tree stump, patting the spot next to him inviting Vegeta to join. The prince continued standing there, arms crossed, glaring down at the third-class warrior.
"Okay… um, Vegeta. It is very important that we talk about this and if you have any questions don't be afraid to ask." Goku heard a growl emanate from the prince at the implication that he would have to ask Kakarot for anything, and hurried along, "Vegeta… do you ever have any… urges?"
"I have the urge to go Super Saiyan and murder you right now."
Goku laughed out loud, "No, Geets. I mean sexual urges" Goku held the textbook in front of his face, revealing a diagram of a vulva, "are you aware of what this is?"
A fist came barreling through the cover of the textbook that Goku had been hiding behind, and into the Saiyan's face, knocking him over and causing blood to gush from his nose. Goku had tears in his eyes as he sat up and looked for Vegeta, only to see the prince quietly flying away from them.
"Oww…!"
Piccolo began to cackle at the scene he had just witnessed, thinking Vegeta may have already been aware of such information.
Despite the cooler air, Bulma was still covered in sweat as she worked on a vehicle outside in the pleasant weather. Covered in grease, the scientist leaned against the metal frame of the car to take a break when she saw her Saiyan houseguest land in the yard, looking as pissed off as ever.
She smirked, "Back already? Was Goku too annoying for you today?"
The prince stopped in his tracks, staring at the human. Bulma was feeling uncharacteristically shy as the Saiyan looked her up and down before stomping away, blushing furiously for whatever reason. Bulma was left alone again, pondering what was going on in that head of his.
