At the park where the special store is now promoting on selling balloons that are brand new to the market, Rico goes walk to one and see the balloons that are yellow with a letter "P" on them. He would then go buy one that cost a dollar and hold it on a strange, walking with it. He then encounter Orihime Inoue that was strolling on the sidewalk and she waved at him, and bend down to his level.

Orihime: hi there Rico, long time no see. Seems like you're here at the park just as me on a fun, summer day.

Rico: hehe, hi Orihime. I really am having fun at the park. The special store just start making balloons for sale and it's really cheap.

Orihime: that's really nice of them making the balloons cheap. I can see that you already have one.

She looks up at the yellow balloon, and stand up straight, giving it a few pokes with her finger. Rico giggles seeing her poking the balloon and walk with her on the sidewalk.

Rico: pretty cool right? I really love how it got the letter "P" on it too. I forgot what it means and why is it on it.

Orihime: who knows. Maybe it's just there fo-

Orihime would accidentally popped the balloon as Rico got startled from the loud pop sound. Her jaw dropped open after accidently popping it, crying with those anime expressions with tears flowing down her cheeks like a waterfall.

Orihime: I'm so sorry for popping the balloon Rico! I didn't mean to do it!

Rico: oh it's alright Orihime, I'd forgot to tell you that these balloons pop easily once you poke it. And they say they do something special after you popped it.

Orihime: oh alright. I wonder what's something special popping it?

Her body starts making hissing sounds and she feels her body tingling and her belly was expanding a bit fast, bulging through her pink shirt as she blushes and giggles feeling her belly and butt expanding too. Rico pat her expanding belly, seeing her body getting rounder and spherical with her arms and legs sinking in her body, making her immobile. Her breasts also gotten bigger as she was really round and inflated like a balloon, flapping her sunken hands and giggling since the inflation feels really good.

Rico: that's what the balloon do after you popped it. It'll blow you up like a balloon hehe.

Orihime: it does feel really good to be so round and full of air. I'm honestly enjoying this so much.

Rico: I'm glad you love being a balloon Orihime. You look really adorable as one too.

Orihime: Awww, thank you Rico. You can play with my round, bouncy body as you like~. *Wink*

Rico: alright my bouncy girl. I'm going to have a fun blast with you~.

He would then get right behind her and crawl up on her back, feeling her large, plushy butt as it feels really big and soft. Rico hold onto her sunken hands and begin to start bouncing on her body, using her as a hopper ball as she bounce around the park and into the city. Orihime was laughing and smiling being used like an inflated toy for his amusement as she continues to bounce higher.

Rico: hahahahaha! This is so fun playing with you! I'm having the time of my life using you as a hopper ball!

Orihime: it really is so fun to be played with. I really do love how bouncy I am hehehehe. We should go higher!

Rico laughs more and fulfilled her request as he makes her go higher, having the time of their life bouncing around the city. After hours that's now the evening, Rico is snuggling on Orihime's inflatable body, putting his head on her large ballooned breasts, and smiling at her warmly.

Rico: this was a really fun day my blimpy Orihime. You really make a good balloon and hopper ball to play with hehehehe.

Orihime: I'm glad you love my inflated body my small little cutie. You can use my body as a bed to relax on after a really amazing day with you.

Rico: thank you Orihime. You're the best friend ever.

Orihime: you're welcome Rico. Now sleep tight and rest on my soft, puffy body. Relax for the night my little cutie.

Rico listens to her, yawning softly as he put his head on her Inflated breasts to use them as pillows, taking his glasses off, and drift to sleep. Orihime smiles seeing the young boy sleeping on her round body, giving him a kiss on his cheek and she fall asleep with him, feeling very relaxed being an inflated balloon for his amusement throughout their fun day.
