After a long day of school, getting out with the students, Rico was waiting for the school bus to come by until he felt someone touching his shoulder, looking up to see a teenage girl with Faye skin, long, brown hair, and wears a denim jacket with a white shirt under it, ripped jeans as well as a both a flower and bead necklace around her neck and a flannel shirt that is tied around her waist. She smiles at him, giving him a gentle handshake.

Mayhem: sup there, kid. I'm Mayhem. It's nice to meet you. You seem to be waiting for the bus a little too long.

Rico: it's nice to meet you too, Mayhem. My name is Rico. It has gotten a bit late to pick us up.

Mayhem: I can fix that issue. Wanna ride with me in my car? I can take you home.

Rico: *smiles and nods* sure. I'll give you something in return when we come to my home. You'll love it.

Mayhem chuckles, holding his hand as they walk to the parking lot to her car that looks decently good, getting inside of it, and she commands the car to his address. Rico was amazed that the car can drive itself like a Tesla, taking them to his home that took 15 minutes. Once they arrived at the mansion/chocolate, Rico lead Mayhem to the backyard where there's an helium tank was set up in the middle of the backyard with the hose connected to it.

Rico: here's a helium tank for you to try out, Mayhem.

Mayhem: a helium tank? What am I going to do with it, Rico?

Rico: it's simple. All you gotta do is put the hose in your mouth and it'll puff you up like a balloon. Are you willing to be my big balloon?

Mayhem: *blushes* oh man... Well, I did drive you home and you're returning the favor, so heck yeah I'll do it for you!

She smiles bright, putting the hose in her mouth, turning on the helium tank as she feels the cold helium puffing her cheeks up, making her belly expand, stretching out her shirt and jacket to expose her swelling midsection along with her butt and thighs inflating, stretching her pants to reveal her butt crack. Rico giggles, patting her inflated belly while watching her getting a lot more bigger and rounder, her arms and legs sinking in her body, leaving her hands and feet sticking out, and her flat chest expand into large breasts that are like big balloons, revealing her cleavage. Mayhem moans softly, spitting out the hose, and finally becoming a big, human balloon.

Mayhem: wow! That felt so good, baby! I didn't know being inflated can feel that amazing~.

Rico: I know right? You look really amazing as a big balloon, Mommy Mayhem. It matches you so well~.

Mayhem: aww, thank you, Rico. How about you can play with me like this? I would love to bounce around and be played with by you~.

Rico: sure. I can do that for you, Mommy. I'll give you a lot more as well~. *Wink*

He gently roll her on her back, climbing on top of her, and bounce on her Inflated belly like a trampoline, laughing loudly. Mayhem giggles, flapping her sucked hands, enjoying being bounced on until she saw him hopping onto the ground, gently rolling her inside of the mansion to the living room, them make her roll on her belly, her breasts bounce a bit, squishing on the ground as she feels him playing with her inflated butt cheeks that made her moan softly, then felt him pulling her pants down to penetrate her Inflated vagina with his small member. Rico giggles mischievously to see her blushing and gasping a bit to feel suddenly full from him gently thrusting in her.

Rico: hehehe. You seem to love this a lot, aren't you, Mommy Mayhem~?

Mayhem: *moans softly* oh yes, I'm loving this so much, baby... I didn't expect you to fill me up like this~.

Rico: that's good, Mommy. I'm going to fill you up with my little peepee since you've been a good balloon to me~.

Mayhem: keep it up, little man. I'm all yours to play with~. *Wink*

Rico continues to keep thrusting, going in and out of her, feeling her wet walls clenching onto his penis, slowly picking up the paste as he touches her inflated, wet clit, teasing her to make her moan lustfully. Mayhem roll her eyes up, flapping her sucked hands fast and wiggling her sucked feet, enjoying him filling her up more, begging for him to keep going, feeling herself wanting to cum.

Mayhem: oh crap, Rico. Keep going. Don't stop for me, please~!

Rico: *panting* good, Mommy. I'm going to let it all out for you~.

Mayhem: yes... I'm going to squirt a lot on you, baby. I don't think I can hold it much longer~!

Rico: that's right... Squirt on your little inflator. I need you to do that for me~.

He moans softly, pounding her gently until he came deep in her inflated folds while rubbing her clit faster, and licking it. Mayhem felt his warmth filling her completely, squirting a lot of her cum all over him, panting to feel him taking his penis out of her. Rico giggles, getting close to her face, and grope and play with her large ballooned boobs that is wobbling, feeling her nipples harden.

Rico: did you enjoy our fun time, Mommy Mayhem~?

Mayhem: I love it so much, Rico! That was the best experience I ever had with you, especially when I'm so full and round which turns me on. Thank you for this, baby~.

Rico: *smiles warmly* you're welcome, Mommy. I'm going to relax on your back and play Twisted Metal. Hehe.

Mayhem: *smiles back* that sounds fun. I'm cool to be your big, inflated beanbag. But First, come closer to my face~.

Rico gets close to her, then feeling her giving him a big kiss, melting into it as they make out for a while until they break the kiss. He climb up on her back with a remote control, playing Twisted Metal, relaxing while Mayhem watch him play the game, smiling as she enjoys her Inflated state after her tough journey through the Twisted Metal tournament she been through, even thinking about floating around with her new best friend playing with her Inflated body and give her more pleasure.
