On her day off with Ada Wong coming over to Ricoy large mansion, wearing a small size red tracksuit with her big butt slightly showing her butt crack ad the word "JUICY" on her pants, knocking on the door to visit her little boy. Rico opens the door, looking up at her, giving her a big hug around her waist due to excitement of seeing her here to babysit him.

Rico: Mommy Ada! You're here right on time!

Ada: *chuckles* someone's excited to see me. I'm so happy to see you again, Rico. What would you like to do today?

Rico: I've thought about something fun we can do together. You'll love it once you try it out.

Ada: I'm looking forward to this, sweetheart. Now, let Mommy scoop you up in her arms.

She carries him in her arms, walking in the hallway as she would nuzzles her face against his, feeling him patting her head gently, giggling from his playful affection. As they go inside of the kitchen, Rico grab a handful of gummies, putting some in Ada's mouth, seeing her swallowing them down her throat, and licking her lips playfully.

Ada: these are really sweet gummies, Rico. What kind of gummies are those?

Rico: they're recently new ones I've made. I'm glad you love them a lot. They're going to expand your body up with air~.

Ada: expand my body? That sounds really interesting. I would love to be inflated for you, baby~

Rico: nice! It looks like your belly is already swelling up, Mommy~.

Ada looks down at her belly that's inflating, stretching out her top tracksuit, patting it like a drum as she puts him down, feeling her butt and thighs expanding, stretching her pants out more. She giggles, feeling herself swelling up a lot more with her arms and legs inflating, raising up as her breasts gets a lot more bigger, wobbling in front of her. Rico gets excited to see her stop inflating, becoming an inflated sumo mommy for him to play with, giving her Inflated belly a big hug.

Rico: do you love your Inflated body, Mommy Ada~?

Ada: yes I really do, Rico! I'm so full and light like a balloon. I love it~.

Rico: sweet! You look so huggable like a big teddy bear. I honestly love you like this~.

Ada: aww, thank you, baby. Come cuddle with your Inflated Mommy~.

She waddle to him, carrying him in her arm as she waddle out of the kitchen with her inflated body wobbling and bouncing, trying not to knock any furniture. Finally arriving in the living room, Rico put his small hands on Ada's large breasts, groping her as she moans softly, enjoying his touch and feeling him now patting her inflated belly, tickling her to make her laugh, and squirm under his touch. She feels him groping her inflated butt cheeks, nuzzling his face in her exposed butt crack as she would wiggle her butt, bending down more to make her pants slip down, showing a lot of her ass crack for him.

Ada: you seem very aroused, baby. I can tell you want to put your small member between my butt cheeks~.

Rico: oh yes I do, Mommy Ada. Your butt is so big and squishy for me to play with~.

Ada: if that's the case, then go ahead and put it inside of me, dear. Mommy would love you to have sex with her~.

Rico: you got it, Mommy! I'm going to put my little peepee inside of your butt right now~.

He takes off his pants, and underwear, revealing his small member that's standing tall like a little flag, putting it between her inflated butt cheeks, and hump her slowly. Ada gasp, enjoying the feeling of him filling her up, wobbling her butt more to match his rhythm, moaning as she role her eyes up, loving this moment with him. Rico put his hands on her shoulders, thrusting in her more faster, leaning in to kiss her lips deeply, and make out with her.

Rico: *moans* there we go, Mommy Ada. It feels so good with my little peepee in you~.

Ada: *panting* oh yes, baby! Keep going for Mommy~.

Rico: I'll keep going for you. I think I'm getting close to cum inside of you~.

Ada: good! Fill your inflated Mommy up with all of your cum~!

Rico: I...I will do it for you, Mommy~!

He continues to keep pounding her large butt more, groping her more as he would release his warmth deep in her ass, moaning from his climax. Ada's mouth was open wide with her eyes crossed, tongue hanging from sexual pleasure, panting from their taboo. She feels him now sitting on her butt cheeks, kissing her cheek as she giggles, and wiggles her Inflated butt cheeks, allowing him to cuddle her from behind.

Ada: you really made me feel so good, Rico. I enjoy this so much~.

Rico: *panting* thank you, Mommy Ada. That was really fun having you inflated like this~.

Ada: *chuckles* I'm glad you enjoyed having fun with your puffy substitute teacher. Or should I say inflated Mommy~. *Wink*

Rico: hehe, you are my big, inflated Mommy for sure. Wiggle and bounce that big butt of yours~.

Ada: sure, dear. Relax on Mommy's big butt~.

She continues to wiggle her big butt for him more, feeling his finger running in between her butt crack, making her smile more, enjoying him teasing her. Rico bounce on her inflated butt more, cuddling her from behind, and nuzzle his face in her neck, loving his Inflated substitute teacher in the red tracksuit that's now an inflated Mommy for him.
