On the day with Rico waiting outside for one of his friends to come over, he saw his best friend, Mayhem walking towards him with her hands on her hips, swaying left and right, plus wearing her new light blue small size tracksuit that he recently gives her. She scoops him up in her arms, nuzzling her face against his playfully.

Mayhem: Rico, my man! It's been a while since we had fun together. Did you miss me~?

Rico: *nods and giggles* of course I missed you, Mommy Mayhem. I have something special for you to try out~.

Mayhem: oh sweet! I also really love the new tracksuit you sent me. It's really snuggly, especially with my butt crack showing, but I still love it a lot~.

Rico: I'm glad you love it a lot, Mommy. Now, let's go inside for me to show you something you'll love~.

Mayhem nods as she carries him inside, kissing his cheek while looking around at his chocolate factory that's really cool and colorful with candy being created and chocolate river flowing down the stream. As they made it to the invention room, Rico takes out a stick of gum from the machine, gently putting it in her mouth, and watch her chew on it. Mayhem's eyes wide to taste a variety of flavors, putting Rico down on the floor, feeling his small hand groping her big butt, and fingering her crack that made her moan softly.

Rico: what do you think, Mommy Mayhem? Do you love your special treat~?

Mayhem: mmmm, it taste really good, baby. I love the flavors that taste like tomato soup, roasted beef, and blueberry. Blueberry pie is actually my favorite flavor now~! *Chew chew chew*

Rico: that's good you're loving it a lot, Mommy. The best part is that the gum is so good that it's starting making your skin fully blue and round~.

Mayhem: *confused* huh? What's that supposed to mean?

She blows a bubble, feeling a bit strange with her nose turning blue, making her notice that her skin was now turning blue. Mayhem wasn't scared or anything, but was getting excited from what's happening to her now that her skin is fully blue and her belly begins to swell up, stretching out her top tracksuit to expose her midsection. Rico steps back, seeing that her butt was swelling up, stretching her pants up to expose a lot more of her crack, and he pat her large butt, feeling how squishy it was from the juice inflating her.

Mayhem: woah! I'm swelling up from this gum, Rico~!

Rico: like a blueberry, Mommy Mayhem. Enjoy the Inflation while it last hehe~.
