"Matty, wake up! Matty!"

Matt struggled into consciousness. He was overheated, drenched in sweat and tangled up in the covers. Mello's hand was shaking his shoulder insistently. He opened his eyes and found himself staring up into Mello's concerned features. "You were having a nightmare," he said. "You were making these sounds."

"No…not a nightmare…" mumbled Matt. He couldn't remember the details of his dream, but it had been nice. Somehow, his underwear had gotten bunched up around his crotch so tightly that it was causing him pain. He squirmed and reached down to fix it, but he realized something was wrong even before his hand reached it. His groin felt all cramped and stuffy. Once his hand was there, there could be no doubt. It wasn't the underwear at fault; it was him.

Matt sat bolt upright. Mello exclaimed in surprise at his sudden movement. "Whoa, Matt, what's with you today? Forget an exam?"

It only took an instant for Matt to realize that there was no possible way he was going to be able to keep this from Mello. "No, it's…there's something go on…down there," he mumbled.

"What is it?" demanded Mello, eyes wide.

Matt shoved the covers off of himself and, with great trepidation, pulled the top of his underwear open just a hair. He grimaced as he looked inside. His dick hadn't just gotten stiff, it had gotten bigger. It felt like a foreign creature attached to him, one he had no control over.

Mello grabbed the waistband of his underwear right out of his hand and yanked it out all the way. Matt gasped and flushed crimson in mortification, but Mello didn't relinquish his grip. "Whoa!" he exclaimed. Then he grinned widely. "Matty! You have an erection!"

"I can see that!" said Matt defensively. He tried to wrestle his underwear back from Mello's hands, but the blonde held firm.

"Quit it!" he exclaimed. "You don't get to hide it from me. That would be the same as keeping a secret, and that's not allowed."

Matt hesitated. He had tried to explain privacy and the concept of the personal bubble to Mello on many occasions, all to no avail. If Matt pushed him away, it led immediately to a crestfallen expression and the plaintive question, "Do you hate me?" It was usually easiest to just let him have his way. Aloud, he said, "Are you sure that those are really the same thing?" At Mello's emphatic nod, he relinquished his grip on the garment. Mello had it around his ankles in an instant.

"Wow," he said, peering at Matt's dick intently. "It's such a weird color! And it's so much bigger! Doesn't it look funny?" He glanced up at Matt's expression, and laughed. "Your face is almost the same color. Hey, you match!"

That, if anything, made Matt redden further. "Shut up!" he hissed. Mello just stuck his tongue out unrepentantly. Matt glanced downwards again and bit his lip. "Um…" He looked at Mello plaintively. "What am I supposed to do?"

Mello's expression sobered. "Don't stick it into a girl's…you know, because then she'll get pregnant and have a baby," he said gravely.

"I know that!" snapped Matt. "But what do I actually do?" Roger had been exceedingly clear during anatomy class about what not to do in the event of an erection. But it had just dawned on Matt that he had never said a word about what to do.

"Um…well…" Mello seemed to be out of his depth as well. "Maybe it'll go away by itself?"

Matt took hold of it. He couldn't not; it was there. Touching it produced a shivery thrill of sweet feeling that made his stomach tingle. Entranced, he wrapped his fingers all the way around it and squeezed experimentally. "Feels good," he said in a hushed tone.

"Yeah, it always feels nice to touch your dick," agreed Mello, rubbing his through his underwear.

"No, like—way better than usual," said Matt. He moved his hand along the length of it, and squirmed.

"Can I touch too?" asked Mello.

"No!"

"Please?"

"Why?" demanded Matt.

Mello recoiled slightly, looking hurt. "I just want to know what it feels like. Why don't you want me to? Aren't we best friends?"

The way his dick felt was too distracting for him to put his heart into an argument with Mello right now. "Okay! You can touch it if you want, weirdo."

Mello pouted. "I'm not weird." He reached out and used one finger to poke the tip of it where Matt's hand wasn't. It sent a jolt of pleasure through Matt's dick and he jerked involuntarily. Mello saw it, of course; it was impossible to get anything past him. He giggled and repeated his touch a few times.

It happened so quickly. All of the sudden, Matt's dick felt amazing, so good that he didn't care that it was spurting liquid out onto the sheets, and didn't care that Mello exclaimed in dismay and jerked his hand back. Then it was over, and Matt was left trying to catch his breath while Mello stared at the goo on his hand with wide eyes.

"You made a mess," said Mello disapprovingly.

"Didn't mean to," said Matt in between pants. "That felt really good. Really, really good."

Mello had brought his hand close to his eye and peered at the off-white substance coating it. "Semen," he said authoritatively.

"Yeah." Then Matt frowned. "I didn't know it could just…come out…like that."

"It's not supposed to," said Mello. "It's supposed to come out when you have sex or wet dreams. That's what Roger said."

Matt shrugged. "Well maybe if you hadn't woken me up, it would have happened in my sleep." He grinned. "But I'm glad I was awake for it. It felt really good."

Mello grinned back. Then he turned thoughtful. "You're supposed to start getting erections when you start to like girls," he said. He peered at Matt's face curiously. "Do you like girls now?"

"Uh…" Matt probed his feelings to see if he liked any of the girls in their class any better than he had yesterday, but came up empty. "I don't think so. I'd know it if I did, wouldn't I?"

"Yeah…I think so," said Mello a trifle uncertainly. He grabbed Matt's discarded underwear and wiped his hand off on it, then huffed a little sigh. "I want to know what that felt like. No fair that you got the first erection. I'm the older one!"

"But you got the first hairs down there, and the first wet dream," Matt pointed out. That reminder mollified him slightly. "As for an erection…well, maybe in a few months," he said, trying hard to keep a straight face. "When you get to be a man too."

"Hey!" Mello punched him in the arm, and Matt laughed as he pulled away. He snagged his underwear from Mello and did his best to wipe off himself and his bed. Then he tossed them into the laundry hamper with a grimace.

"You're all back to normal now," Mello commented, staring at Matt's crotch.

"Yeah." Matt curled up. Now that the good feeling part was over, embarrassment was starting to settle back in. "Quit looking, now, would you?"

"'Kay." Mello bounced off the bed and went to the dresser, where he dug out a new pair of underwear and tossed them at Matt. "C'mon, let's go shower."
