During the day at hopes peak academy in the gym, Makoto Naegi and Maki Harukawa are hanging out there, eating lunch together on the benches. Maki finished up her food and look at Makoto with a warm smile.

Maki: that was a really good sandwich you made for me Makoto. thank you so much for giving me food.

Makoto: you're welcome Maki. I'm happy you like my cooking.

Makoto gives Maki a hug and she hugs him back, kissing his cheek. they let each other go and Maki looks at his tracksuit he's wearing.

Maki: and also nice new tracksuit you got. where did you go it from?

Makoto: oh thank you. I've found the tracksuit from the special store. they're recently just start selling them 50% off.

Maki: that's cool they're selling tracksuits now.

Maki then think about the blue tracksuit on Makoto as a light bulb pop out of her head.

Maki: Makoto, there's something I would like you to try out. it's a special treat you're going to love.

Makoto: sure, I'll try it out. I can't wait to get something special from you.

Makoto eyes sparkle up with excitement while Maki put her hand in her pocket and pull out a stick of gum, showing it to him. he looks at it with a confused expression.

Makoto: oh. it's a stick of gum.

Maki: not just a stick of gum. it's a special one I got from the special store. you should try it out.

Makoto grab the gum from Maki's hand, unwrap it up and pop it in his mouth. Once he start chewing on it, he start tasting some really sweet, delicious flavor that was really addicting.

Makoto: mmmm~ this taste so good Maki. they really did a good job on this gum.

Maki: well I did read the manual on it that it'll give you a really good, juicy experience.

she wink at him and he giggles while continuing chewing on the gum. He blows a bubble from his mouth and his nose start turning blue. Maki smirk seeing his nose and face turning blue slowly and he looks at her.

Makoto: is there something on my face mommy roll?

Maki: oh it's nothing, just relax and see for yourself sweetie boy.

Makoto then looks at his hands that's turning blue. He gets scared seeing his skin is now fully blue and he feels a little bloated in his belly.

Makoto: my skin is blue! what's happening to me Maki!? I feel so bloated and full!

Makoto's belly gurgling and rumbling, slowly expanding with juice as he looks at his swelling belly. Maki then put his hands on his big belly and jiggle, and patted it as it slosh juice in his belly.

Maki: hehe, you look so adorable when you're so chubby Makoto. I honestly would love to have a big boy like you.

Makoto blushes from her squishing his belly as he still chews on the gum. He then feel his butt and thighs getting bigger and swelling up as he turn around, seeing his pants getting tighter and was slipping down, showing his butt crack.

Makoto: woah! my butt is getting really big!

Maki almost had a nose bleed seeing her boyfriend ass a lot bigger as she then groped his butt and patted it. Makoto blushes shades of blue as he moans from her groping his sensitive body.

Maki: so chubby and thicc too Makoto~.

Makoto: mmmm~ Maki. your touch is so good on my sensitive body~. *chew chew chew*

Maki: good~. now swell up into my blueberry boy and I'll give you a lot of fun~.

Makoto nod to Maki as he swells up so big that his arms and legs slowly sink into his round, blue body making him immobile. his bulge gets erected and bulges through his pants as his tracksuit tightens around his blue body, showing his full belly and his naval. Makoto's cheeks puff up with blueberry juice as he can only moan and he was in pleasure. he rocked back and forth on his crotch as he flaps his hands in excitement, enjoying being a blueberry.

Makoto: mmmph~ *Muffled* Maki. this feels so good to be a round and full blueberry~.

Maki: I'm happy that you're enjoying yourself Makoto. after all, you look really hot as a big blueberry boy~.

Makoto: *muffled* Awww, thank you for the compliment.

Maki climbs up onto his round body and gets close to his face, putting her hands on his puffy cheeks and gives him a big kiss on the lips. She moans while making out with her blueberry hope boy and he kisses her back, moaning in pleasure. while they make out, she tastes some juice from his mouth and slowly lets go of his blue lips.

Maki: mmmm~ tasty juice you got hehe. I love you so much my sweetie.

Makoto: *muffled* I love you too my mommy roll.

Maki smiles at Makoto and he smiles back warmly. she then climbs down from his round blue body, and putting her hands on his belly.

Maki: let's get you on a rolling. we're going to have a lot of fun together.

Makoto giggles and moans feeling Maki starting to roll him out of the gym class outside. She smiles thinking about a lot of more fun with her blueberry boyfriend as she also has a stick of gum in her pocket.
