The sun shone through the scattered gaps in the clouds on this mild spring afternoon over the south east of Elwood City. George Lundgren, the fairly quiet moose boy, was sitting by the window upstairs in his bedroom, waiting patiently for his rabbit friend Carl to come over for the afternoon to play something they found accidentally on the internet. A weird 'game' involving blowing up balloons and feeling good about it. As in, really good. He didn't remember all of the specifics of what the site said, but was still ready to give it a try with Carl today. A few moments later, see his friend approaching and knocking on his front door..


“Oh goodie! Carl is here!” He said to himself as left his room and walked downstairs and jumped off the staircase, catching the timid bunny by surprise but was nonetheless happy to see him.


“Oh hello George!” Carl replied with a faint smile on his face as he picked up his plastic bag he had brought with him.. “It’s great to see you again!”


“Yeah! Wanna come upstairs to my room?” George quickly leads Carl upstairs to his room, who follows him quite closely behind. Once in George’s bedroom, they both sit together on the bed to decide on what to do first.


“So, did you get that box of balloons so we could try...the thing?” George turned and asked Carl in curiosity. 


Carl nodded as he rummaged through his bag, taking out a plastic box containing a dozen or so  party balloons that were eager to be blown up. “Yep. We had some of these left over from my birthday.” He said.


“Well, let’s give them a go!”


George looked out of his bedroom door to see if anyone was nearby before hastily closing it, placing one of his pillows near it to hopefully mask any loud sounds the two of them made. He jumps back onto his bed next to his friend before beginning to undo his trousers, sliding them down his ankles. Carl looked quite hesitant as he watched George and slowly mimicked his actions.


“Is something wrong, Carl?” George asked him, putting his arm around his shoulders.


“It’s, well...I’ve never seen another willy before and I’m worried you’ll laugh at mine.” The rabbit kid looked away from George, beginning to blush.
“Don’t worry, I’ve never seen another one either!” George smiled back at Carl, doing his best to reassure him. “How about we show them both at the same time?”
“..,Okay then.”
“Ready? One, two, three!”


On the count of three, the two boys took off their underwear down to their ankles, exposing both of their flaccid cocks out in the open for them to ogle at. George’s penis had a considerable amount of foreskin, with it giving a fair amount of overhang at the tip but Carl’s was the complete opposite, being circumcised with a glossy pink glans and a visible scar behind his cockhead.


Carl was completely mesmerised by his friend’s member and couldn’t resist reaching out to touch the tip, gently grasping ahold of the shaft and pulling the moose's foreskin down, eventually exposing his glans out, being a brighter shade of pink in comparison. George didn’t make any attempt to stop him, apart from a minor shudder as his friend moved his foreskin up, down and around, with a faint scene of the moose’s musk with every move. It was all so alien to him that a penis could look and feel anything like George’s. 


“Mind if I touch your willy, Carl?” George asked, moaning gently as he began to become slightly erect from the touching.
“Go ahead, I need mine to be bigger before we play with the balloons anyway.” Carl replied without looking up at him, clearly still fixated on George’s own to be embarrassed anymore.


Feeling Carl’s circumcised cock felt so much different to George, if the glossy yet dry smoothness of his glans was enough of a giveaway. The scent of it was much less pronounced but still noticeable compared to his own and the lack of moveable skin made it feel much more stiff to handle, but he still enjoyed touching it. 


A quick rub and a squeeze of the rabbit’s shaft was already enough to get him semi hard and within time, the two boys both had their dicks standing erect, pointing up at slightly different angles. Lengthwise saw their shafts at a roughly similar length, with George just beating Carl thanks to his stretchy foreskin but losing in terms of ball size where Carl’s were much bigger.   


“Okay, wanna start blowing up the balloons now, Carl?” George asked, sitting upright and now gently stroking his own length to keep himself hard.


Carl looked back sheepishly, returning to his nervous emotion again before replying. “I dunno...maybe we should practice first?”

“Okay sure, but how?”


“How about I try it by sticking my willy into your willy? It has that stretchy bit in the end where mine could fit.”


The idea of sticking their cocks together was baffling to George. But at the same time, some spark of curiosity was lit in his head. After a quick think, he told Carl that he was okay and shuffled on the bed to face their dicks together. George pulled back his foreskin and guided his cockhead to Carl’s, making a gentle ‘smush’ as they touched.


“Hehe, that tickles, Carl!” George giggled as Carl’s cockhead nuzzled gently against his own, now being completely covered by the moose’s wrinkly and malleable foreskin. “Go ahead and see if that trick works now.”


Carl took a deep breath, rhythmically thrusting the pit of his stomach to start making some pressure, releasing a puff of air through his shaft that tingled inside him and started to fill his friend’s foreskin, moaning a bit before taking another breather to pump it some more. The sensation of air gradually inflating George’s foreskin became rather erotic for the moose and began to enjoy it with ever blast that came out of his friend’s cock, stretching it out into an appearance of a light brown balloon. 


Once it reached at least three times its size, the pressure was too much and Carl’s cock was suddenly spat out of his friend’s foreskin, leaving a small string of precum between them. The air rushed out of George’s ballooning tip at a rapid pace, making a clear ‘wooshing’ sound for a few seconds before returning to normal. He was now blushing after finding that entire sequence pleasurable and was eager to try it out with the balloons they had.


“Mmhmmm, that felt...really good, Carl!” George chuckled, slightly moaning as his foreskin returned to normal size. “Now I really can’t wait to begin blowing up these balloons!”


“Y-Yeah, me too!” Carl nodded as he reached a green balloon for himself and gave a blue one over to George. “It feels so good making your willy blow air through it.”


“I know! I’m so glad we found out how to! Let’s give it a try now!”


The boys slid the opening of their balloons over their shafts tightly snug before making a start of getting them blown up. George copied the same thrusting and breathing motions made by his friend earlier, though clearly wasn’t as ‘experienced’ as Carl was. Every puff of air forced through their cocks stretched the balloons out more and more, with the rubbery surface creaking with pressure with every blow made and after a few moments, Carl had already blown his balloon up considerably whilst George was lagging behind a tiny bit. 


It wasn’t too long until both of their balloons were blown bigger, the air squeezed into them from their throbbing shafts stretching the surface enough to be translucent. Carl could see his reflection on his green balloon when he wasn’t looking at his cock beginning to dribble more with further thrusts it made. George was close to feeling rather tingly deep inside too, impressed with how big the two of them had blown up their balloons too. 


“Mhmm, you gonna make yours bigger, Carl?” George moaned out loud, watching his cock give out another sustained blow into the blue ball of rubber.


“A-Actually, I think I’ll keep it this big and just rub my willy for a bit because it feels good like this.” He replied back as began to take both hands to hold his own shaft and make those repeated rubbing notions as precum began to fill his balloon. “I’m starting to feel a bit weir-”


But before another word could be said by Carl, George couldn’t hold the sensation any longer. His cock blew so much air in one go that his balloon burst in an instant! Carl covered his ears from the sound as he watched his moose friend moan out and gasp as his throbbing cock shot out a few ropes of his cum onto the floor with some dribbling out of his foreskin to fall down the shaft as he laid back from the pleasure. Suffice to say that he enjoyed this new thing they found out about 


Continuing to rub his dick at a steady pace, Carl did eventually climax shortly after, squirting a few shots into his rubbery ball that culminated at the base of the balloon, giving the image of a thick lake of cum at the base. Some of the fluid dribbled out as he became as soft as George and the two boys in their afterglow looked back at each other and back at the box on the bed. They counted at least 20 more deflated rubbery balloons there. Waiting to be burst by their cocks.


“How about round two?” George asked Carl, smiling yet still flushed breathing heavily from his orgasm.


“...Later.” Carl responded. “Only if I can blow into your willy again.”


“Deal. Just don’t...blow it up, if you know what I mean.”
