In the evening outside with Rico riding on Yoruichi Shihouin's back, cuddling her from behind while she walks her way to the park as she smirks at him, getting to their destination, holding a helium tank where they have their fun ideas for their night out.

Yoruichi: this is going to be an interesting night for us to try out, Rico. Are you ready for some fun~?

Rico: I'm so ready for us to have a lot of fun in the sky, Mommy Yoruichi. You'll be so big and floaty~.

Yoruichi: damn right I will, hehe. All we gotta do is set up the helium tank and we're good to go~.

Rico: I got the hose for you to use in case we don't have one~.

He gives her the hose, giggling to see her connection it to the nozzle, setting up the tank as they were prepared for their flight. Yoruichi looks at Rico over her shoulder, kissing him playfully before she would put the hose in her mouth, and turn on the helium tank as its start hissing, making her belly swelling up a bit fast.

Rico: cool. The helium tank is really filling you up so fast~.

Yoruichi: *muffled* I can see that, baby. I really love being inflated for you so much~.

Rico: keep swelling up for me. I love to see you get so much bigger like a blimp~.

Yoruichi: *muffled* you got it, baby. Hang on tight~.

She continues to inflate herself more bigger, feeling her butt and thighs expanding, causing her pants to stretch out to reveal her butt crack, floating from the ground while Rico clings onto her back, watching her body expanding really huge. Yoruichi moans softly, feeling her arms and legs puffed up, and her breasts becoming really huge like two giant balloons, spitting out the hose, finally becoming a very large, ninja blimp for their fun night.

Rico: now you're fully ready for our night in the sky, Mommy Yoruichi. You look so hot like this~.

Yoruichi: *muffled* aww, thank you, baby. This is going to be really fun to see the city below us~.

Rico: I know right. Since you're a ninja blimp, we can go fly wherever we would like without us getting notice~.

Yoruichi: *muffled* that's true there. I can kinda float us somewhere private for us to get a little more busy. Now, relax on my back and let's enjoy ourselves, baby~. *Wink*

Rico nods, sitting on her back as they go high up from the park, floating above the busy city with the lights on, making it a beautiful scene with the moon shining on them, and the stars shine bright like a diamond. Rico put his small hands on Yoruichi's large inflated butt cheeks, pulling her pants down more further to tease her exposed butt crack, making her moan softly while working his way up to her Inflated belly, rubbing her and tickling her belly button and groping her large breasts, squishing them together.

Yoruichi: *muffled giggles* you really love seeing me like this, do you, Rico~?

Rico: I really do, Mommy Yoruichi. You're so big and squishy. I'm really enjoying this night with you~.

Yoruichi: *muffled* I'm glad you love me as your big blimp so much, baby. We should fly at your place and get busy if you know what I mean~?

Rico: *blushes and smiles* I think I know what you mean. Let's go to my mansion where we can have a lot more fun for the night~.

They would continue their flight around the city, across the forest where they found his mansion below them, landing down gently as Rico hops off her back, opening the door and help her get inside. Rico hugs her Inflated butt cheeks, pushing her through the doorway, successfully getting through as Yoruichi smirks at him, feeling his small member getting between her cheeks, gently thrusting in her, moaning softly to feel him filling her up.

Rico: you're so tight, Mommy. I love doing this with you~.

Yoruichi: *muffled moans* me too, baby. Keep pounding your little peepee in Mommy's big butt~.

Rico: I'll keep going for you. I'm going to pick up the pace~.

Yoruichi: *muffled* good boy~.

Rico continues to thrust in her more, feeling her inflated butt bouncing on him, picking up the pace to keep going while hugging her large butt cheeks. Yoruichi panting, rolling her eyes up to feeling him sucking on her Inflated clit that's throbbing in his mouth, squirting all over his face, and feeling him filling her up with all of his love. They both panting with Rico cuddling on her big butt, feeling her twerking under him.

Yoruichi: *muffled* that felt amazing, Rico. Thank you for filling Mommy's butt with your love~.

Rico: you're welcome, Mommy Yoruichi. This was a really fun night doing this with you~.

Yoruichi: *muffled giggles* I'm glad you enjoyed your day with me. Cuddle on my butt more while I twerk for you~.

She continues to shake her large booty, making it bounce and wobble a lot for him to cuddle on it between her cheeks, feeling very relaxed. Rico's little peepee gets hard again, poking between her inflated folds, giggling to look at her smirking at him as they're going to have a fun, blimpy night of love until the sunrise.
