In the afternoon inside of the large mansion with Rico walking to the front double doors, opening it to see it was a tall woman with short blue hair, and wearing a blue tracksuit that's hugging her curves. It was Bulma that smiles at him, bending down to his level to pat his head gently.

Bulma: hi there, little cutie. I've got an invitation to come here for some fun. I'm Bulma, and I'm something of a scientist myself. *Wink*

Rico: it's nice to meet you, Bulma. My name is Rico. You can try out a special treat that you'll love.

Bulma: a treat, huh? Well then, time for me to try out his special this treat is~.

Rico: *chuckles* come follow me. I'll show you everything you'll like~.

He giggles, holding her hand, leading her through the hallway as he would put his hand on her big butt, playfully pulling her pants to expose her butt crack. Bulma smiles, playfully swatting his hand away, wagging her finger in a playful manner as they go inside of the invention room, getting a stick of gum from the machine, putting it in her mouth, playfully smacking on it, and tasting its delicious, sweet flavors.

Rico: do you love my special gum~?

Bulma: oh yes I do. It's really sweet and delicious. I can taste almost any flavor~. *Chew chew chew*

Rico: nice. The cool part about this is that the gum is now going to turn your skin blue. Look at yourself now, Bulma~.

Bulma: huh?

She looks at herself, seeing that her skin turning fully blue, a bit surprised from her new look, patting her belly that's swelling up in front of Rico, looking down at him, embarrassed about this. Bulma feel her butt and thighs expanding, looking over her shoulder to see her butt getting bigger, making her pants slip down to expose her butt crack, turning around as she gets a lot more bigger and rounder, feeling her arms and legs sinking in her body with her breasts getting huge, stretching out her top tracksuit and her cheeks puffed up with juice. Rico looks up at Bulma that's now a big, round blueberry, giggling to see her in such a vulnerable situation.

Rico: that gum actually turn you into a blueberry, Bulma. How do you feel~?

Bulma: *muffled* I feel very full and also aroused. I love this so much, Rico~!

Rico: that's good! I'm happy that you're enjoying it so much. I think you look hot as a blueberry~.

Bulma: *muffled giggles* that's really sweet of you, baby. Come here and roll me all you like~.

Rico gets close to her, putting his hands on her belly, gently pushing her to roll her out of the invention room, through the hallway, hearing the juice sloshing inside of her, giggling to hear her moaning. Bulma was in a bliss, enjoying the feeling of being used as a personal plaything, feeling him stopped rolling her, and climbing up on her body to her face, rubbing her Inflated cheeks with his small hands.

Bulma: *muffled* mmmm, so good, baby. I love it when you touch me like that~.

Rico: *chuckles* I'm getting so hard looking at your face, Mommy Bulma. I would like you to kiss my little peepee with your plump, blue lips~.

Bulma: *muffled* oh dear, you're a naughty boy. But if that's what you want, then I'll do it for you~.

Rico: ok, Mommy. Here you go~.

He takes his pants off, showing her his small dick, making her blush a shade a blue on her Inflated cheeks as he gets close to her face, feeling her plump lips kissing it gently, making him giggle and moan. Bulma then open her mouth, sucking the tip with her tongue swirling around on it, feeling him thrusting in her slowly, moaning to taste his small penis.

Rico: *moans* OHHH, it feels so good, Mommy Bulma. Keep going for me~.

Bulma: *muffled moans* mmmph... Mmmm~.

Rico: that's what I like to hear. You're going to make me have a climax~.

Bulma giggles, continuing to suck him more, tasting his precum that's leaking inside of her mouth, continuing to give him more pleasure. Rico moans loudly, couldn't hold it in more longer as he would release all of his cum deep in her mouth, seeing her cheeks puffed up a bit bigger, hearing her gulping it down. After their little fun, he sits next by her head, patting her gently and relax.

Bulma: *muffled* your little peepee was really good, Rico. I really love tasting your cum so much~.

Rico: *giggles* I'm glad you love it a lot, Mommy. You should stay as a blueberry for today. I'll juice you tomorrow~.

Bulma: *muffled* nice. I really love being your blueberry scientist. I hope this day never end. Now, give Mommy some kisses, baby~.

Rico: *chuckles* ok, Mommy Bulma~.

He leans closer to her face, giving her a big kiss as they moan, making out together as he put his hands on her large breasts, squishing them to make her moan more. Bulma giggles, giving him lots of kisses all over his face, smothering him with her inflated cheeks, and really loves being his big, blueberry scientist that would love him to play with her all day long like how she's chewing on the gum.
