After working on an Evangelion robot, getting out of the workplace, Shinji Ikari had gotten a message from Misato that requested him to go visit her small best friends place, and sent him a free blue tracksuit. An hour later of him arriving at the mansion, he knocks on the door, seeing it open, and looks down at Rico that was happy to see him.

Shinji: hi there. My name is Shinji Ikari. I was sent here by Misato to meet Rico.

Rico: it's nice to meet you, Shinji. I'm Rico. I'm happy you actually came here to have some fun with me. Nice blue tracksuit Misato gave you.

Shinji: *chuckles* thanks. It's pretty tight, but I love it.

Rico: hehe, good. Now, come inside and try out the gum I have for you.

Shinji nods, getting inside of his mansion, walking with him through the hallway, amazed to see how a mansion so big enough to have literally everything. He felt Rico's hands on his butt, squeezing it that made him blush, giggling as he doesn't mind him teasing him. As they go in the candy room, Rico grabs a stick of gum, giving it to Shinji, and seeing him putting it in his mouth, chewing on it as the flavors now beginning to spread on his tongue.

Rico: what do you think about the gum, Shinji?

Shinji: it actually tastes really good. I can taste a lot of flavor on it. I now can taste blueberry pie~! *Chew chew chew*

Rico: that's really awesome you can taste a lot of flavors. The cool part is that the more you keep chewing, your body will change~.

Shinji: what do you mean by that, Rico~? *Smirks and blows a bubble*

Rico: take a good look at yourself~. *Giggles mischievously*

He points at Shinji's nose that's turning blue and his whole skin. Shinji looks at himself, feeling his belly swelling up, lifting the top tracksuit to expose his midsection. He blushes, smiling a bit as he looks over his shoulder, seeing his butt and thighs swelling up, making his pants slip down to expose his butt crack. Rico giggles seeing him swelling up, walking back to see him getting a lot more rounder and spherical with his limbs slowly sinking in his body, his chest start becoming a lot bigger and his noticable bulge through his pants, poking his bulge. Shinji moans softly, rocking back and forth as he's now a big, juicy blueberry boy still chewing on the gum.

Shinji: *muffled* mmmph...oh this feels so amazing, Rico. So this is what Misato experienced~.

Rico: yes she did, Shinji. You're now a big blueberry boy just like Misato. I can see that you're turned on from this~.

Shinji: *muffled* oh dear, I guess I kinda have a secret kink being inflated, hehe. Would you like to play with me, please~?

Rico: sure. I'll play with you, my big berry boy~.

He gently pushes him to roll him out of the candy room through the hallway, singing a song about him that made him giggle. Shinji moans softly, enjoying being rolled around by him, making it to the bedroom where he felt his hands touching his bulge, making him blush, then rubbing his large, blueberry butt, and teasing his exposed crack. Rico chuckles to tease him, climbing up on his belly to tickle him, and rubbing his chest, hearing him laughing, and flapping his sucked hands in his divots.

Rico: *chuckles* how are you feeling now, Shinji Berry? Enjoying being so big and blue~?

Shinji: *muffled laughter* y-yes I really am! This is heaven, Rico. I really love this so much~.

Rico: good, hehe. I'm going to use your belly as a bed since it's pretty dark outside.

Shinji: *muffled* I wouldn't mind being your blueberry waterbed. You really made me so happy, Rico. I honestly would love you to inflate me more often~.

Rico: I'm glad you enjoyed being a blueberry a lot. We'll have a lot more fun tomorrow morning~.

Shinji: *muffled* I'm totally looking forward to this. Now, go to sleep, bud~.

Rico nods, putting his hands behind his head, slowly closing his eyes, and fall asleep while hearing the juice sloshing in Shinji's body like an ocean wave. Shinji smiles warmly, sighing in relief as he would fall asleep with him, thinking about this whole day was really worth being a giant blueberry for his new friend that's going to give him more of a fun time that'll await the next time he inflates him.
