In the morning at the park with Rico sitting on the bench, watching his Mommy, Chiaki Nanami that's playing Space Jam with his other Mommies that are involved in the basketball court too. Rico claps for Chiaki's performance, giving her a bottle of water to rehydrate herself.

Rico: you're doing very well, Mommy Chiaki. Keep up the good work.

Chiaki: thank you, Rico. I appreciate your support a lot. This is a really fun game like the NBA series. *Pats his head*

Rico: I'm always here for you. That's what a son f-

Chiaki: WATCH OUT, RICO!!!

Rico looks up to see one of his Mommies large butt was going to land on him, but Chiaki pushes him out of the way to safety only for her to be squashed. Rico gets up really fast, seeing her flattened on the floor like a pancake with swirls in her eyes. He was shocked to see that she was in this state, touching her paper like hand to check on her.

Rico: Mommy Chiaki!? Are you okay!?

Chiaki: uhh...

Rico: you're really flat like a pancake... I know how to help you out. Wait right here.

He runs to the storage room, grabbing an air tank out of it, dragging it to Chiaki as he would put the hose in her mouth, turning it on as the helium begins to start inflating her body. Rico gets on her back, seeing her belly inflated, showing her belly along with her butt and thighs expanding, stretching out her basketball shorts and her breasts gets larger, making her basketball shirt more taught. Her arms and legs swells up, sinking in her body and her cheeks puffed up really big, spitting out the hose as she's now a big balloon in the basketball court. Chiaki looked confused, seeing herself inflated while Rico looks at her with a smile on his face.

Chiaki: *muffled* w-what happened, Rico? Why am I inflated?

Rico: what happened was you saved me from one of my Mommies almost squishing me and you got flat like a pancake, so I puffed you up like a big balloon.

Chiaki: *muffled* oh, that makes sense. Wanna go back home and cuddle up? I'm really relaxed being a big balloon like this, baby~.

Rico: sure. Hehe. We can go play together since you got squished and inflated~.

Chiaki cuddles against him, her inflated body squishing his small body in a warm, protective embrace, patting his head gently while they float away from the park, through the city as they go back home to the large mansion. Now inside of the bedroom, she gives him lots of kisses, her inflated cheeks smothering his face as he giggles, getting happy again, and cuddling on top of her, nuzzling his face in her Inflated breasts, causing him to get hard, poking her Inflated belly with his small boner.

Rico: *chuckles* my little peepee is hard, Mommy Chiaki. You really made me excited~.

Chiaki: *muffled giggles* I can see that, dear. You can roll Mommy up and hug my large butt. You deserve to have this gamer's booty~.

Rico: sure, Mommy. You're my second best Mommy ever~.

Chiaki: *muffled* thank you, Rico. Now, put that little peepee in me. I need you inside of me~.

Encourage by her words, Rico gets off her, gently rolling her on her Inflated belly, hugging her large, inflated butt cheeks, pulling her shorts down to reveal her Inflated vagina that's glistening from how turned on she was, gently insert his small member between them, and slowly thrust in her. Chiaki moans softly, flapping her sucked hands, enjoying the feeling of him stretching her out, twerking her large butt for him to cuddle on.

Chiaki: *muffled moans* good, baby. Go a little faster for Mommy~.

Rico: *panting* ok, Mommy Chiaki. You're very wet down there. It really turns me on~.

Chiaki: *muffled* good. That's what I like to hear. Enjoy hugging Mommy's big butt more~.

She moans loudly, feeling him picking up the pace, gasping to feel his small hands touching her inflated clit that's pulsing out cum, getting her more wet. Rico moans softly, thrusting his small member in her fast, rubbing her Inflated butt cheeks together, nuzzling his face in her ass crack as he felt himself now leaking precum from the tip of his penis.

Rico: *moans loudly* oohh, Mommy... I'm getting so close to cum. I'm going to fill you up~.

Chiaki: *muffled* there we go, baby. Fill Mommy up with your love. I need all of you in me~.

Rico: ok, Mommy Chiaki.... Here it comes~...

Chiaki: *muffled panting* OHHH, YES, BABY! RIGHT IN THE GOAL RING~!

She feels him pumping his cum deep inside of her Inflated pussy, making her moan loudly as she's at her climax, squirting on his body with her cum, panting after her climax broke down like a water dam. Rico panting, taking his penis out of her, hopping on her back to cuddle up, kissing her Inflated cheek, giggling as he really did enjoy this moment with her.

Chiaki: *muffled* Rico... You did so good, my boy~.

Rico: *giggles* you're welcome, Mommy Chiaki. You deserve this after what happened in the morning~.

Chiaki: *muffled* I really do need this, baby. Let's have more fun with me kissing your little peepee nonstop~.

Rico: sure, Mommy. I would love you to do that for me please~.

Chiaki: *muffled* give it to Mommy, sweetheart. This gamer girl wants to play more games with you~. *Wink*

Rico cuddles between her cleavage, lining up his member as he feels her lips giving it a deep kiss and licking it that made his giggle and squirm under her. Chiaki moans softly to taste their juices from their taboo, her eyes fluttering slowly to keep giving it more kisses and licking it more while they both enjoy their day after their silly morning from the Space Jam basketball court that they planned on going back to have more fun there.
