After a long day of hopes peak academy where everyone is walking out of the school home, Rico and Chiaki Nanami are walking together on the sidewalk to hangout together at her place to play some video games and have more fun.

Rico: that test went well in class. At least we don't have homework for the weekend Chiaki.

Chiaki: mhm, I'm happy we got free time together. We can have a lot of fun at home.

Rico: nice. I would love to show you something cool when we get home.

Chiaki nod and give Rico a piggyback ride as she carry him to her house. 10 minutes later, they arrived at her house, opening the door and get inside. Chiaki put Rico down on the ground, setting their stuff down on the floor.

Chiaki: get comfy because we're going to play lots of video games together. I got two remote controllers for multiplayer games.

Rico: Nice! I wanna have more fun with you by puffing you up like a balloon. You're going to love it like the last time you become a blueberry with Ms. Jericho at the chocolate factory.

Chiaki: *turn around and smirk* oh yeah, I remember that field trip? That actually sounds pretty fun. Maybe you should puff me up like a balloon. I would love that~.

Rico: cool. Come closer to me so I can puff you up~.

Chiaki put her console down, walking towards him and bend down to his level. She close her eyes, puckering her lips for Rico as he then kiss her lips deeply, and blow air in her mouth. Her cheeks puff up with air along with her belly inflating, making her shirt and jacket stretch out. Chiaki moans softly, enjoying Rico puffkissing her as her butt and thighs expanding, lifting up her shirt to expose her panties and butt crack. She float from the ground, feeling her body expanding more bigger the more air he blows into her mouth, making her so big like a balloon. Rico giggles seeing her puffy cheeks so red, tying up her wrist with a balloon string and let her float from the ground, close to the ceiling.

Chiaki: *muffled* mmmph... That felt so amazing Rico. I'm so full and lite as a feather~.

Rico: yep hehehe. You're so adorable when you're inflated like a balloon. You fit the role so well my Chiaki balloon~.

Chiaki: *blushes and muffled* Awww, thank you. Play with your Chiaki balloon all you like buddy~. *Wink*

Rico: sure. Let's go outside for a walk. We need some fresh air~.

He giggles, holding onto the balloon string, and take her outside for a walk around the neighborhood. Chiaki giggles softly while floating in the air, bobbing around while looking down at Rico as he looks up at her, seeing her cute smile on her face, showing how much she's enjoying being his balloon toy. An hour later, They come back home as Rico sits on the couch, Tying Chiaki down with a small bag full of rocks to prevent her from floating up to the roof.

Rico: that was really fun walk around the neighborhood right Chiaki~?

Chiaki: *muffled* it really was fun. I was floating around feeling the breeze on my inflated body. It felt amazing~.

Rico: I'm glad you love it so much. You don't mind if I can play on your games? You can help me out on it too.

Chiaki: *muffled and smiles* of course you can play on my game. I can't really reach the remote while Inflated, but I can guide you on the game.

Rico: thank you Chiaki. You're the best.

He sets up the game in the console, grabbing his controller as the game booted on screen, and start playing while Chiaki would guide and tell him about the game. Rico smiles, pulling her down and sit on her back as he enjoys her company and playing the video games she loves to play the most.
