On a normal day with Serena having plans to go hangout with Rico, she decided to wear a red Juicy couture tracksuit that's bright red, matching her hat that she usually wear. The word "JUICY" was on her pants in bold letters made out of diamond. She walk to his house, knocking on the door, seeing it open with Rico holding a small bag of gummies.

Rico: hi there Serena, long time no see. Ready for our day?

Serena: I really am ready for some fun. What's with the gummies in your hand?

Rico: oh this is just some new gummies that I think you're going to love a lot. Want some of it?

Serena: *smiles* sure, I would like some. Can't say no to some sweets.

Rico: sweet! You can have the whole bag.

He passed her the gummies, and she open up a bag, pouring most of it in her hand, and toss them all up in her mouth. Serena chew them, gulping it down her throat while she walks with Rico somewhere they can have fun together. She felt something strange in her stomach she can't explain what it is.

Serena: Rico? About those gummies you've gave me, what was in them? I kinda feel weird.

Rico: those gummies are pretty special ones. You may feel weird, but it goes away and it'll give you something special you can use only once.

Serena: oh, that explains. It doesn't feel like something happened to me.

Rico: well it's simple. All you gotta do is inhale deeply and see what happens.

Serena takes Rico's advice and take a deep breath, inhaling a lot of air. Her chest gets larger, making her breasts expanding slowly like two large balloons getting inflated with air, lifting her jacket up to show her belly button. Her butt and thighs expanding too, stretching her pants, showing some of her panties and her butt crack. Rico giggles seeing her body has transformed into an Inflatable hourglass shape, with her breasts and hips wobbling around and bouncing each step she takes.

Serena: wow. My body has changed so much. That felt so good~!

Rico: told you you're going to love it. Once you inhale all of the air, your breasts and butt gets bigger, and can keep the way it is until you decide to blow all the air out to deflate~.

Serena: this is permanent as long as I want it to be huh? If that's the case, I'm keeping these for a while so you can hug and touch them~. *Wink*

Rico: sweet. That's really nice of you doing that for me Serena~.

Serena gives him a big hug, smothering his face with her large breasts that feel really soft like pillows. He smiles, hugging her back with his arms wrapped around her waist, placing his hands on her butt, squishing them together as they jiggle under his touch, making her giggle. She place Rico on her back, and continue walking with her new curves wobbling around each step she takes, making him look at her curvy body was really mesmerizing.

Rico: I really do love your new body Serena. It's nice that you decided to keep it for a while until you decide to deflate~.

Serena: thank you Rico. Even if I did deflate back to my normal size, I might plan on getting those gummies for myself to have my curvy body back~.

Rico: that's sweet. that means you'll have lots of advantages when you can inhale, making your body any size you like~.

Serena: let's go buy more of them to expand my body. This is going to be our hangout for today. We gotta explore more about the gummies~.

Rico: alright, lead the way you milfy pokemon trainer while I relax on your back~.

Serena giggle and walk more, bouncing her body up and down to amuse Rico's playful nature as he hold on tight on her shoulders, enjoying the fun piggyback ride. He put his chin on her shoulder, closing his eyes while Serena carry him around for a while, enjoying the feeling of him being so close to her body that's now ample, admitting to herself that she should totally use more gummies for her own amusement.
