One year ago...

The heat in Nick's bedroom was starting to get unbearable for him and his friend Jason. It was the middle of summer and Nick's parents had a thing about not running the air conditioner at night. His dad would always say it was about saving money on the electric bill and that it was supposed to be cooler at night anyways. But in any case, the two boys were roasting. They were sitting on the floor in front of a fan, stripped down to their underwear in an attempt to cool off.

"Uuugh, so friggin' hot man..." Nick complained as he wiped the sweat from his forehead.

"Yeah..." Jason mumbled as the fan blew in his face. "Nights like these make me wish I could take my fur off."

"Haha, yeah. Too bad it's stuck to us." Nick lifted open the leg holes on his boxers, trying to get the fan to blow some cool air inside. "About the only other thing we could take off is our underwear."

"Pfft, maybe we should." Jason smirked. "I'd welcome anything that would cool me off..."

Nick laughed, but his friend's words lingered on his mind. It may have been a joke, but the heat was so bad that he was seriously beginning to consider it. Shyly, he turned back to Jason, "Hey... would you mind if I did?"

"Seriously?" He chuckled, but soon shrugged, "I mean it's your room dude, I don't care. Go for it."

Nick stood up and pushed his thumbs inside his waistband. With one easy push, his boxers fell down around his ankles, finally giving his sweaty nether regions the air they sorely needed. He stepped out of his underwear and kicked them to the corner of the room, then sat back down in front of the fan with his legs spread wide open.

"Ahhh..." The breeze blew through all of his moist crevices. It felt so nice that he wasn't even worried that someone could walk in and see him like that. The comfort was unreal.

"Feels that good, huh?" Jason asked.

"Yeah!" Nick smiled. "You can join in if you want."

"Heh, alright." Jason got up and started to undress as well.

Nick leaned back and relaxed as he was starting to feel more comfortable. He reached down to adjust his private parts, peeling his balls off of his thighs and flipping his dick upwards so that the underside could get some air. It laid across his bare crotch with the head resting in the dip between his crotch and stomach.

It wasn't long Jason sat back down beside his friend. Nick was laid back far enough that he could only see his friend's backside, but his exposed rear-end made it obvious that he was also baring all. "Ah dude, you were right. This is so much better."

Neither of them had any problem with being nude in front of the other. They had been best friends for years and had already seen each other naked on dozens of occasions, so they were already pretty well acquainted with each other's bodies. And besides, they were both boys, so it wasn't like they were going to see anything they hadn't seen-

"Woah!" Nick exclaimed as he sprung back up.

"Hm?" Jason had laid back just as his friend had been doing moments ago. The shocked expression on the fox's face confused him; what had him so surprised? His friend was staring at his body, specifically one region of it. "Yeah? It's a penis. You've got one too."

"But dude, yours is huge!"

"Huh?" Jason looked back down. It was laying upwards similar to how Nick did his, except his tip was resting snugly inside his belly button. "I mean, I guess? I'm older dude, of course mine's gonna be bigger."

"It wasn't that big before!"

"Really?" Jason looked down again, then shrugged. "I don't know. It looks about the same as it always has to me."

Nick took a look back down at himself. His own manhood seemed so small and undeveloped by comparison. He suddenly became self-conscious about having it exposed in front of Jason's massive man meat and pulled his legs in to hide.

"Dude, come on, you don't gotta be embarrassed. Like I said, I'm older, so of course I'm gonna be bigger."

"I know, but..." Nick rested his chin on his knees, "What if mine is just small?"

"Hmm, let me see yours again. Just to compare."

Jason watched as Nick reluctantly lowered his knees and spread his legs. Getting a better look at him, he gained a greater understanding for just how undeveloped his friend's body was. He may have grown a little taller and lost most of his baby fat, but his penis wasn't even half as long as Jason's and he didn't have any grown-up fur yet either.

"Hmm, yeah, I see what you mean."

"Argh, dude!" Nick grew agitated and covered himself up again. "Don't say that!"

"I mean, you're only eleven, man." Jason tried to reassure him, "I'm sure it's gonna grow. And besides, your soft size doesn't even matter anyways. It only counts when you're hard."

"What do you mean?" Nick asked.

"I don't know, it's just what I've heard. If you're gonna measure it, you're supposed to do it when you're stiff."

"Well how is that supposed to work? Do you just have to keep a ruler handy and wait until you get a boner?"

Jason stared back at him, dumbfounded and unsure of what to say. "Uh..."

"What?"

"...You don't know?"

"Know what?"

"You know... How to make yourself get hard."

"Uhh... No? Why would I want to do that?"

Jason covered his mouth and tried to hold back his laughter. "Hang on dude, let me show ya." He clasped his penis between his fingers and began to stroke himself. "All ya gotta do is wiggle it."

Nick tried to mimic what his friend was doing, putting two fingers around the base of his boyhood and wiggling it side to side. "Like this?"

"Yeah, just keep doing that until it gets stiff."

Nick continued to play with himself, watching as his willy gradually swelled between his fingers. It was starting to harden up and getting a fair bit longer too.

"See?" Jason said, "It's not THAT small."

Feeling a little less self-conscious, Nick looked over to see how his friend was doing. Jason's manhood was getting stiffer as well, but it didn't look like it had gotten much bigger. But despite that, it was still quite sizeable.

"Yours is still a lot bigger..." Nick remarked.

"Well... Yeah. You caught up a bit though. Just give it a year."

Nick looked down at himself again. Getting curious, he stood up and looked around, then went over to his school backpack and rummaged around inside.

"What are you doing?" Jason asked.

"Getting a ruler." He pulled one from the backpack shortly after saying it. "I wanna measure."

Nick put the ruler against the base of his stiffy. He wasn't sure how much he was supposed to press it into his crotch, but he just pushed down until it started to hurt.

Jason got up and came over to look. "What's it say?"

"Hmm... About three and a half... four inches?"

"Let me try." Jason took the ruler and pressed it against his own manhood.

Nick looked over and tried to see the measurement, but it was hard to get a good view. He looked back up at Jason and waited. "Well?"

"Five and a half."

"Is that good?"

"I... don't know."

Both boys stood around looking at their erections and scratching their heads. Neither one was sure how big a normal one was supposed to be.

Not knowing what else to do, Nick extended a finger and pushed down the tip of his penis, then watched it spring back up afterwards. "So, is there a way to make it go down now?"

"Uhh... Hehe... Sort of." Jason blushed, "You gotta make it harder first, though."

"Harder?"

"Yeah, watch." Jason climbed up on the bed and laid on his back. He took his member in his hand and started stroking himself again, leaning his head back and closing his eyes in the process.

Nick got on the mattress and sat on his knees, watching the cat's hand move slowly up and down his shaft. It was like Jason was in a trance, but he seemed to be enjoying it. His lips curled a bit with each stroke, seeming anguished yet joyful at the same time. Nick couldn't make any sense of it, but he continued to watch with great interest.

"Hey," Jason panted, "Got any tissues?"

"Uhh..." Nick looked around the room, "Yeah, here." He pulled one from the box on the nightstand and handed it to Jason.

However, instead of using it on his nose, Jason took and draped it over his penis. The stroking resumed with the tissue covering the tip, as if this were the setup to some sort of magic trick. 

Nick continued to observe with bated breath as he tried to figure out what his friend was up to. He stared at the tissue, wondering what he was going to use it for. But soon he noticed a spot forming, a bit of moisture. Was this trick making him pee a little? Was that what the tissue was for?

Jason suddenly grunted and began thrusting his hips in the air. Each time his rear left the mattress, the tissue became more and more wet. He slowly started to settle down, panting as he rested on the bed. Pulling the tissue away, he wiped his penis off as it gradually returned to being soft.

"What did you just do?" Nick asked.

Jason opened his eyes again and looked over at his friend. He then held out the wadded-up tissue and showed him what was inside. It looked almost like snot, except it was white and clearly came out of his penis.

"Wait..." Nick examined the mystery substance and tried to recall what he learned in school. "Is that... sperm?"

"Yep!" Jason nodded proudly.

"I didn't know you could do that! I thought you had to be way older!" The fox was amazed at his older friend's abilities, but something else troubled him. "Wait, so... did you just have sex?"

"Nah... Well, sort of. It's more like I 'did it' with my hand. It's fine though, cause it's not like I can get my hand pregnant or anything."

"Huh, yeah..." Nick had to think about that one for a moment. It made sense, if you didn't have to worry about pregnancy or STDs, was there really any danger? He looked back down at his own penis, which was still stiff as ever. "...So, you just rub on it until the sperm comes out?"

"Something like that. It helps if you think about naked girls, like their butts and their boobs and stuff. Just keep going until it feels like you're gonna bust, then relax and let it happen."

Nick tried to re-enact what he had just observed. He took a tissue and put it over his stiffy, then twiddled himself between his fingers. He continued rubbing on it for a few minutes, hoping that something would happen, but it didn't seem like he was getting anywhere. "It's not working. What am I doing wrong?"

"Nothing! You're doing it right, you just gotta close your eyes and think about sexy stuff. Don't worry about making sperm, just try to relax and have fun with it."

After another couple of minutes passed, Nick decided to try something new. He closed his eyes and imagined himself naked with a really hot girl. She had beautiful hair, vibrant fur, and she was totally naked too, her body glistening with sweat. The mere mental image was enough to make his dick get even harder. The more he thought about her, the more he felt his breathing quicken and his heart pound faster. It didn't take long before he was gasping for air and sweating all over.

"Nngh, are you sure this is right?" He asked, stroking himself faster now, "It feels like my boner's getting worse."

"It's fine dude, that's supposed to happen. It'll go down after you're done."

Nick continued fantasizing about beautiful naked chicks. This time, he pictured a supermodel. She had long blond hair, the silky smooth fur, and the cutest smile. Her breasts were big, her butt was round, and her legs were long and shapely. He couldn't help but stare at her perfect body, and his dick kept growing and growing. Soon, he was stroking himself so hard that he could barely stand it anymore.

"Oh god, here it comes!" Nick cried out.

He grabbed his cock and squeezed it tight, trying to force something out. There was no way he was going to last much longer. His body tensed up, and his hands started shaking. Then, without warning, a massive wave of pleasure washed over him, sending waves of ecstasy through his entire body.

"Aaaaahhhhh!" he screamed, his dick throbbing uncontrollably. His body went limp, and he collapsed onto the bed. He laid there panting for a few minutes before Jason crawled over to check on him.

"Well, how was it?" Jason asked.

"Fucking amazing..." Nick was so exhausted that he could barely move. Pulling his hand away from his deflating penis, he took a look at the used tissue. "Huh? Where's the sperm?"

Jason leaned over and looked as well. Sure enough, there was nothing in there. "Huh, I guess you're not old for that enough yet."

Nick laughed, then sat up. "Yeah, I guess not. Still, that was pretty great."

The two boys were drenched after their little exploration session. It probably wasn't the best idea to masturbate when they were both already sweating buckets, but what's done was done. They both returned to sitting on the floor in front of the fan, neither bothering to get dressed after all they had been exposed to. Now that they had finished beating their meat, they were solely focused on beating the heat.
