Birthday Balloons 3
Rounded Rom
Rom was a young wolf completely obsessed with balloons.
Who wouldn't be obsessed with balloons? They start off so small and grow to massive sizes! It's a dream come true for all those who want to get bigger.
"I wish I was as big as a balloon." Rom would tell himself. Being the smallest of the pups, he loved things that could magically change sizes.
"Rom? You in here?"Terrance entered the room with a soft smile.
"Hey Terr."
Terrance is Rom's favorite cousin, because he was the only one who didn't make fun of his size.
"I brought something for you." He held out a plastic bag of balloons of various shapes and sizes. "I know you like 'em."
"Terr!" Rom jumped off his bed and hugged his 15 year old cousin, "Thankyouthankyouthankyou!"
"I also brought a special pump. Wanna try it out?"
"Yes!"
"Okay, this is gonna be a bit weird, but you're going to love it!" Terr told Rom as he sat him down on the bed.
"That's okay, just tell me!"
"It'd be easier to show you. Take off your clothes."
Too excited to question, Rom took off all his clothes, his fluffy tail wagging with so much excitement.
"Okay, calm your tail, it's gonna make it harder to put these in yer bum." Terr plugged the pump into the wall and started inflating a long yellow balloon.
"Wait ...what?" Before Rom could offer anymore protest, Terr lifted his tail and started showing the yellow balloon up Rom's ass. When it was fully inserted, the balloons forced Rom to sit with perfect posture as it realigned with his spine.
"This is gonna keep you supported for the next ones." He started inflating five more long balloons, and he shoved three into Rom's butt. He then started to knead the balloons through the skin forcing them to take their place in Rom's legs and tail. The last two were shoved down Rom's throat being forced into his arms.
Roms stood there on the bed looking comical with his appendages beings stiff and cartoony. He tried to talk, but only had more balloons stuffed down his throat, four small round balloons. Two for his biceps, and two for his pecs.
As scared as he was, Rom couldn't deny that he liked his cousin kneading and massaging his body to get the balloons in the right places. And when he looked in his mirror, he loved the appearance he now had. A slightly balloon-musclular build.
Rom was now entirely stiff, unable to move, and unable to speak in nothing more than squeaks from the latex balloons rubbing against each other inside him.
"Glad you like it. Now this last one is going to be too big to force inside you inflated, so I'm gonna have to inflate it while it's inside you." He took the last balloon out of the bag, a large red balloon.
He pushed the balloon into Rom's anus until only the opening of the balloon was showing. "Sorry about this part, Rom. But the pump won't fit in-between your cute little cheeks," he gave Rom's bubble butt a good grope and it squeak in response. "So, I'm gonna have to do this the old fashioned way." He forced his muzzles between those two perfect furry globes and blew with all his might into the opening of the balloon.
"SQUEAK!" Rom's eyes widened at the intrusion but was helpless to stop it as he felt a pressure in his stomach. If I could, I'm sure he would've looked down, but in his restricted inflation, Rom could only see what new shape was being blown into him by looking in the mirror.
A huge round sphere made it's home at Rom's belly. It grew and grew till he was sure it would pop inside him.
Terrance pulled his muzzle out of Rom, and tied the end of the balloon before shoving it all the way inside Rom. "How's that feel?"
"Squeak!" Rom smiled.
Terrance patted Rom's pregnant looking belly, "Now comes the real inflation!" he reached out his hands and started to tickle Rom's sides and arm pits.
Rom's body started shake as all his muscles constricted trying to block the tickle attack. But the balloons we're holding him stiff until, pop, pop, poppoppop, POP!
All the balloons inside him were being popped by his flexing muscles like bubblewrap. Finally he had moment again.
"Here it comes!" Terr grinned as he looked at his young 7 year old cousin.
Rom was stretching his tense muscles when all of a sudden he took a deep breath, but he couldn't exhale. He kept inhaling, and it wouldn't stop.
"The gas in those balloons wasn't just air, when you popped them, they started joining with the blood in your body"
Fwoomp, Rom was back in his restricted state, but he was still blowing up. His muscles blowing up, but no muscle was bigger than his belly. Which was now bigger than his head.
"It's exciting the oxygen molecules in your body and making them multiply. I know you're learning multiplication in school, so if all the oxygen is doubled in your body, what would that be if that was then doubled, and then that was double and it kept going?"
Rom was startled and excited about his body becoming a huge balloon, finally he was getting what he wanted. To magically become bigger. But how much longer could this last? Even he knew all balloons pop at some point.
"Haha, you look like a gay blow-up doll."
Rom now had the body of a 16 year old bodybuilder but his head was still that of a 7 year old. He flexed his ballooning pecs and biceps watching how they grew.
And then, just when the pressure would surely pop him, just as it was getting too tight to bear, the inflation stopped.
"Hm. Looks like the gas solution got all used up," He poked the giant (now at his eye-level) roid gut on the 18 year old bodybuilder torso of his 7 year old cousin. "I was hoping maybe a bit bigger. Anywho, don't worry, all this air will turn into muscle over the next few days."
"Terrance this is amazing! It's so cool!" Rom flexed his pecs letting his older cousin have a good feel. "So, can I do you next?"
"Sure, but I can hold a lot more balloons than you. We'd need to go to the store."
"So, now I'm your blow-up doll?"
"Yeah I guess you are." Terrance nuzzled his cousin's belly which he nows sees would be big enough for him to curl up inside of.
"One last question. What's a blow-up doll?
