Around the dark, scary night of Halloween where everyone was trick or treating and scaring people, Rico was riding on Kyoko's back, enjoying their time trick or treating. They both dressed up as Willy Wonka and the chocolate factory with Rico dressed as Willy Wonka and Kyoko dressed as Violet Beaugarde. They went back home, seeing the whole house light up blue everywhere, and they set up the candy on the table until Rico notice a stick of gum on the table.

Rico: check this out Chub chub. I found a stick of gum on the table. Maybe a machine kinda created it while we were gone.

Kyoko: that's a familiar looking gum. I'm assuming it might be James that left it there for you to give it to me to try it out.

Rico: that might be the case since I've got a new candy that's a medium size shaped pumpkin. I'm thinking about giving it away to Heartless since I know he loves eating a lot.

Kyoko: true, he's going to enjoy it a lot while he's still outside with Kari looking for more candy. Let me taste the gum my little Willy Wonka.

Rico giggles, passing the gum to her as she unwrap the wrapper off it, and pop it in her mouth. Kyoko start chewing, and tasting the delicious, sweet flavor, and would play along with Rico as they both roleplay as Willy Wonka and Violet Beaugarde.

Kyoko: taste like a three course flavor. Like roasted beef, tomato soup, and blueberry pie, plus ice cream. *Wink while chewing*

Rico: I warned you about the gum hehe. Your nose is turning violet. *Giggles mischievously*

Kyoko: really? That's really strange. What's happening to me Rico Wonka~?

Rico: that's what happens when the ultimate detective doesn't follow the rules~.

He giggles seeing her skin turning blue, hearing her chuckle while she chew on the gum. Kyoko's body started to swell up with blueberry juice, filling her belly and straining her jacket as she turned around, looking at her butt swelling up, stretching her pants. Rico pat her belly seeing the ultimate detective becoming a lot more rounder and spherical with her arms and legs sink into her body, and her breasts expanding with juice, lifting up her jacket more. Her cheeks swell up with juice, moaning softly as she's now a fully round and ripe blueberry. Rico chuckles seeing her rocking back and forth gently, and hear the juice sloshing in her body.

Kyoko: *muffled* mmmph... Help me Mr. Wonka. So full~.

Rico: I can help you out, but I got no Oompa Loonpas so you'll be just a blueberry for a while~. *Giggles*

Kyoko: *muffled* well dang. Wanna roll me around and cuddle me~?

Rico: of course I would love to cuddle and roll you around. The ultimate detective is now the ultimate blueberry. Let's sing the chewing song~.

He place his hands on her body, gently pushing her to roll her around, giggling as he takes out a small flute, blowing into it as he sings the song. Kyoko moans softly, enjoying the moment of being rolled around by her small Willy Wonka that's now bouncing on her body like a trampoline and doing some flips. Rico stop rolling her and relax between her large, blue breasts, rubbing her swollen cheeks as they look at each other eyes full of love and affection.

Ric: this is honestly the best Halloween ever to play with you~.

Kyoko: *muffled* it really is baby. You're a really good Willy Wonka for this moment~. *Giggles*

Rico: I really am hehe. And you're my best Violet Beaugarde to be a giant berry for Halloween. Who's my blueberry detective~?

Kyoko: *muffled* I am. Give this berry a big kiss my little baby~.

Rico nods to her gentle command, leaning closer to her blue lips and kiss her. Kyoko moans in his mouth, kissing him back, feeling his hands rubbing against her swollen cheeks and tasting some juice from her mouth. Rico relax on her round, blue body, hearing the juice sloshing inside of her as he close his eyes, falling asleep since they had a long fun night together in Halloween.
