Biology: 101

WARNING: Very OOC. Contains descriptions of various yaoi relationships, including one between Gohan and Dende. It also contains scenes of mutual masterbation. So, you've been warned. Don't whine to me if you don't like it. I don't own 'em, but I should. For Dani, my favorite hentai!

The sun blazed in the still air above Capsule Corps. without even the tiniest of breezes to relieve its scorching glare on the earth. The heat was unbearable for the two children sitting dejectedly below.

Gohan sighed for the umpteenth time. "This sucks! Everyone else gets to go comepete in the fighting tournament, while I have to stay here and study. Sometimes I really wish I didn't have a mom, like you do, Dende."

"Guru wouldn't let me go either, and I just wanted to watch."

"Oh yeah." Gohan sighed again and dropped his head into his lap. His voice came out muffled and distant. "What are we gonna do? It's so hot!"

"It is quite warm."

"It feels like the sun is sucking up all my power. I don't even think I can fly!"

"Maybe we should move and sit in the shade."

"It would still be hot," Gohan replied testily.

"Well, back on Namek when it was really hot we went swimming..."

Gohan jumped up excitedly. "Hey! Yeah, that's a great idea, Dende!" His smile quickly faded though, as he remembered Chichi's demand that he study. "My mom will never let me go, though."

"Do you have to tell her?"

"No, but she'd see me if I tried to sneak home and grab my swimsuit."

"What's a swimsuit?"

"Huh? 'Yknow, shorts that you wear when you go for a swim. Don't you have any of those on Namek?"

"No. We just take all our clothes off."

"You swim NAKED!?!"

"Yes...you can move a lot faster in the water without heavy, wet clothing dragging you down."

"Oh yeah. I forgot that you have big monsters in the water back on Namek. Speed isn't so important here. We mostly swim to have fun."

"Oh...and you need to wear swimsuits to have fun?"

"No way! We're gonna have lots of fun without 'em! 'Cmon, Dende!"

Grabbing Dende's arm, Gohan raced off on foot, heading for the nearest lake. The small Namek stumbled behind him, confused but anxious to keep up with his excited friend. Gohan let out a cheerful laugh as he reached the water's edge, then hurriedly proceeded to strip off his heavy clothing.

Dende stood frozen, averting his eyes shyly, as as Gohan let his gi fall to the ground in a tumbled pile, then turned towards him with his hands on his hips, clad only in his tight, white briefs. The Namek's brow furrowed as his eyes were drawn to the small bulge in the front of his friend's underwear. Unfamiliar with the human anatomy, Dende was puzzled by the noticeable mound between Gohan's legs, and couldn't tear his eyes away. He didn't have to wonder for long, as Gohan's briefs followed quickly behind his training clothes to join the growing pile of discarded garments on the shore. Dende's childlike, curious expression turned into an open-mouthed stare as he regarded Gohan's muscular, naked body. Sweat glistened on the other's pale skin, and Dende's breath began to grow irregular.

"Dende?" Gohan's voice cut through his friend's stunned haze and made the Namek's eyes snap back up to meet his own again. "Hey Dende! You okay? You spaced out there for a second. You still wanna swim?"

"Huh? What? Oh!...yes, I still want to swim."

"Aren't you going to take your clothes off then?"

"Of course. I'm sorry, Gohan." Dende clumbsily fumbled with his loose clothing, nervous about how the other boy would react to his physical differences. Gohan's hand on his shoulder made him jump and spin, eyes wide with shock. Both hands tightly held the waist of his pants up against his bare, green torso. His breathing was strained and his face flushed warmly, though unnoticeably.

Gohan's voice was soft with concern. "Are you sure you're okay, Dende? You're acting really strange. We don't have to swim if you really don't want to..."

"NO! No! I want to. I just..."

"What?"

Dende let his eyes drop to the ground, then his pants. He cringed as he heard his friend gasp, squeezing his eyes closed even tighter. He glanced up, though, when he heard Gohan's gentle, hesitant whisper.

"Dende...?"

His eyes were watery as they rose to meet the human's and his voice was barely audible.

"I...I'm sorry,Gohan."

Gohan's expression was identical to his friend's earlier one, as he stared openly at the Namek's naked form.

"Dende, what are....are you a girl?!?"

"No...I..."

"What are you?! I thought you were a boy!"

"I am! Well, sort of. We Nameks are all asexual."

"WHAT?!?"

"We have no gender."

"You mean you, and Piccolo, and Guru,...you're all...nothings?!"

"I AM NOT A NOTHING!" Dende screamed, tears starting to stream down his small face. "I'M NOT! I HATE YOU!"

Gohan stood frozen as his normally meek and soft spoken friend broke into tears, yelling insults, then tore off across the sky, flying eractically. It took him a moment to recover from the shock before he took off in pursuit of the distraught Namek. He caught up with him easily, as the other's blurry eyes were complicating his navigation. Jumping onto his back midflight, Gohan used his weight and the element of surprise to force Dende back to earth. They landed in a shallow mud puddle, with the human still stradling his friend. Mud oozed up to mix with the sweat already sticking to their bodies, making their skin slick. Dende realized this and twisted quickly. Gohan promptly slipped off, unable to hold onto the slippery skin beneath him. Dende was on his feet in an instant, eager to escape, but the slick mud caught him offguard as well, and he fell back down. Gohan grabbed his wrist quickly, to avoid another attempt at escape.

"DENDE! STOP!" Gohan cried desperately. "I want to talk to you. Quit running away!"

"I don't want to talk to you," was the biting reply.

Gohan recoiled from the angry boy, releasing his wrist, but pressed on anyways. "I'm sorry about what I said. You know I didn't mean it. I was just...surprised."

"Humph. I was surprised too, but I didn't have to insult your entire species."

"I know. I said I was sorry! I ju..what do you mean you were surprised?"

Dene turned his head, expecting to see the human laughing at his poor joke, but realized Gohan was sincere in his question. He really didn't know why Dende was shocked by his nude body.

"That," Dende replied bluntly, pointing at Gohan muddy penis.

"This?" replied Gohan, stupidly, reaching down to grasp and lift his child-sized member. "It's a penis. All guys have 'em."

"Nameks don't."

"Oh yeah. Sorry."

"I'm glad we don't! It looks stupid! Like you have a tail growing from the wrong end!"

"HEY!" Gohan replied indignantly. "SHUT UP!"

"What do you even do with it? Anything? Or is it just another dumb useless human thing, like hair?"

"NO! It does lots of things! I pee with it and...uhhh...I..."

"Hehehe...yeah, it's really useful!"

"My Daddy says one day, when I'm A LOT older, I can use it to have babies with a girl."

"So? I can have babies too, without a girl."

"Welllll...it gives you a really nice feeling when you rub it fast. It gets a lot bigger too. You can't do that."

Dende looked at Gohan skeptically. "What kind of feeling?"

"Just a really good feeling. I dunno. It's hard to explain. Yamcha says it feels even better if someone else rubs it, but I never tried. Yamcha knows A LOT about that stuff."

"What stuff?" Dende had calmed down, and grow curious again. Gohan was relieved and relaxed visibly.

"Sex. He knows everything! If you ask him when he's drunk, he'll tell you all about it." Gohan hesitated for a minute. "Just don't tell my mom about that."

"I won't. Nail sometimes talked about stuff like that too. Feelings and body stuff. He called it love though."

"That's what Krillin calls it too."

"Krillin? Oh...does he have a penis?"

"Sure! I told you, all guys have 'em."

Dende took a deep breath and looked Gohan straight in the yes. "I'm sorry I made fun of you, Gohan."

"That's okay! No problem!" Gohan replied, flashing a V sign. "Now we're even!"

"Yeah!" Dende laughed.

"Dende?"

"Yes?"

"Do..do Nameks have sex?"

"I think so. I saw Nail and Hamma together once. They were rubbing each other down here and moaning." Dende gestured to his nether regions. "I was scared, so I ran back to Guru and told him. He said that's how Nameks make love. I think it's the same thing as sex."

"It sounds the same. I went over to the Kame House once to ask Krillin if he wanted to go fishing, but I found him naked with Yamcha, and they were rubbing each other too. Krillin wasn't moaning though, he was making weird sounds. Like this," Gohan said, and demonstrated Krillin's orgasmic cries.

Dende sat deep in silent thought, trying to understand all this new information. Gohan watched him, deep in thought himself. He came to a resolution.

"Dende? Were Nail and Hamma best friends?"

"Yes. Why?"

"Well, so are my Mom and Dad, and they have sex. Krillin and Yamcha are good friends too. Maybe all best friends do it."

"Maybe..."Dende said slowly, wondering where Gohan was going with this.

"I think so! And I think since we're best best friends, we should do it too!"

Dende was caught offguard. "Are you sure that's a good idea?" He asked worriedly. "I mean...you're a human and I'm a Namek."

"So? That didn't stop us from being friends."

"You're right." Dende looked down timidly, and inadvertently glanced at Gohan's penis again. He felt his face grow hot and quickly looked up again. "How are we gonna...'yknow...do this? I've never done it before."

"Me neither. Uhhh..." Gohan thought for a minute. "let's just do it like Krillin and Yamcha did. OK?"

"Okay," Dende replied nervously.

Gohan slowly rose onto his knees and crawled towards Dende. Kneeling in front of his friend, the human smiled akwardly, then placed his hand onto the smooth, openless space between his friend's legs. Dende gasped at the cold, sudden touch. His friend's hand quickly withdrew.

"Was that wrong?" Gohan asked worriedly.

"I dunno," Dende replied honestly. "I didn't feel anything special."

Dende regretted his bluntness as he saw Gohan's face fall, crushed by disapointment and frustration. He felt as though he had failed his friend. Squaring his shoulders and forcing down his customary, hesitant shyness, Dende bit his lip and boldly reached out to grasp Gohan's penis.

Everything froze.

Gohan's head snapped up instantly. "Huh?! Wha..." His voice fell away into a soft, drawn out moan as Dende rubbed his thumb along the length of the underside of the human's shaft. When he reached the tip, he slowly traced a circular pattern around the head, then bent down and kissed it.

"You're my best friend, Gohan. I want to make you happy."

Gohan couldn't reply. He was still struggling to catch his breath, as his chest heaved and his lungs burned. He had never felt anything like the sensations now tearing through his small body, and he didn't know how to react to them, or their giver.

Dende smiled loyally up at his friend, then moved his attention back to the other boy's penis. He suddenly glanced back up again with a confused expresion on his face.

"What are these?" He asked curiously fingering Gohan's balls.

"Huh? Oh, those are my testi..iiiiii," Dende's subtle fingers roamed over the testicles, eliciting deep moans from Gohan.

"Testies? Oh!" exclaimed Dende. Gohan tried to correct him, but a series of teasing squeezes from the young Namek sent him into a state of oblivion. He could only moan his pleasure as Dende began to use both hands, one massaging the small balls, the other steadily pumping the length of Gohan's shaft with increasing speed and pressure. Dende laughed eagerly as Gohan began to scream his name, then shuddered and came with a satsified groan. He went to wipe the sweaty hair from his friend's forehead, but stopped when he noticed the white substance stuck to his hand.

"Huh? What is this?" He rubbed it between his fingers, then gave it a sniff. Still unsure what it was, he brought his finger tips to his mouth, and his small tongue darted out for a taste. "Hmmm..."

"Eeewwww!" Gohan cried. "Don't EAT that! Dende, you're GROSS!" Gohan teased.

"Why? What is it? It tasted ok..." Dende began to grow panicky.

Gohan tried to answer through his laughter. "That's cum! 'Yknow, seeds for making babies. Only girls are supposed to eat it."

"I thought it tasted good."

"Really?!" Gohan's hand darted out to catch Dende's wrist and pull the Namek's hand in so he could taste it himself. He slowly sucked Dende's fingers, then smiled up at him. "Yeah. That does taste good."

Their faces were only inches apart now. Their eyes seemed glued together until Gohan's slowly closed. He leaned in and softly kissed Dende's lips, then pulled back to catch his friend's reaction. Dende looked puzzled, then smiled.

"That was nice. Can I try now?"

"Sure!" Gohan replied, then added as an afterthought, "Remember to close your eyes. Yamcha says only losers kiss with their eyes open."

"Okay." Dende awkwardly leaned in and pressed his lips gently against the other boy's. He remembered to close his eyes tightly. He jumped as Gohan's tongue snaked out and ran across his lips.

"Wha..what are you doing?"

"Giving you a tongue kiss. Yamcha says they're the best kind."

"Oh. Okay."

"Close your eyes again."

Dende obeyed, and Gohan sloppily licked both his lips, then bit the bottom one. Goahn pulled away, and dende was about to open his eyes, when he felt the tiny tongue start exploring his neck. It found a little hollow on the left side, and the human's teeth began to nip at the tender green skin. Dende tried to pull away, but Gohan held him still.

"Don't Dende. I'm giving you a love bite....OK! Done!"

Dende opened his eyes and looked into Gohan's smiling eyes. He couldn't help but smile back.

"This is great, Dende! Sex is FUN! Now it's my turn to do you, so lie down."

"You don't have to..."Dende protested weakly.

Goahn ignored him and grabbed onto his shoulders, pushing him onto his back. Kneeling between Dende's legs, he contemplated the green skin. Then he determinedly brought both hands down, and began petting Dende's privates like he would a cat. Dende laughed hysterically.

"STOP! That TICKLES!" His tiny body shook. Gohan removed his hands, thought a moment, then moved his face down towards the space. The laughter died quickly as Gohan's tongue once again began to play along his skin.

"Whaaattt...are yoouu....doing?" he moaned, breathing rapidly.

Gohan glanced up. "Licking you. Yamcha says everything feels better with some tongue." His attention was focused back on Dende's space, and it wasn't long before his protruding tongue sent Dende over the top, crying out the human's name as he came.

The both lay spent, panting under the sweltering sun.

"I'm sticky," Gohan finally said, breaking the silence. "We never did go swimming. Do you still wanna?"

"Welll..."

"What?"

"I'd rather do that again."

Gohan laughed. "We can! Yamcha says it's even more fun in the water. And he should know!"

Dende grinned. "Yamcha sure knows a lot!"

Gohan replied excitedly, rising to his feet,"Yep...but one day I'm going to know even more than him!"

"I can't wait!" Dende answered, then took his friend's hand. Together, they both flew off into the horizon.
