In the afternoon, in the backyard where Rico and Misty had a lot of plans for their time as he brings a helium tank for her to puff her body up for Airborne August that's almost over. Misty smiles, carrying him on her back as she grabs the hose, looking at him over her shoulder.

Misty: ready for this day together, baby~?

Rico: *nods* yes, Mommy Misty. I'm ready for you to be all big and puffy again, but more bigger~.

Misty: *chuckles* that's good, dear. Hang on tight, we're going to have a fun ride in the sky~.

Rico: yes, Mommy~!

He hang onto her back tightly while Misty puts the hose in her mouth, turning on the helium tank as the cool helium flow into her mouth, puffing her cheeks out, making her belly expand big that's stretching out her shirt and suspenders along with her butt and thighs that's getting bigger, stretching her shorts to reveal a lot of her butt crack.

Rico: you're swelling up really good, Mommy Misty. Keep it up~.

Misty: *muffled* thank you, baby. I really love inflating for you so much. It feels amazing~.

Rico: I'm glad you love being inflated. Become a big blimp for me~.

Misty: *muffled giggles* yes, baby. A big Misty blimp is coming~. *Wink*

She continues inflating more as her arms and legs puff up, raising upwards, her flat chest starts to get bigger, becoming breasts that are like two large balloons, showing a lot of her cleavage. Rico was amazed to see Misty so huge, and big, taking the hose out of her mouth as they float from the backyard to the sky, becoming a giant blimp for him.

Misty: *muffled* that feel really good. What do you think, Rico~?

Rico: I love it a lot. You're so big and floaty just like a blimp, Mommy Misty. You look very adorable like this~.

Misty: *muffled* aww, thank you, baby. I'm happy to be inflated for you. Let's go fly around for a while~.

Rico: ok. Let's go fly above the city~.

They go float from the mansion to the city, looking down at it, seeing the beautiful view of how busy it was with cars driving, and people also pointing up at them. Rico chuckles, cuddling on her back, relaxing as they finish floating around for a while, flying back to the mansion where they have more plans ahead for them. Once back in the mansion, Misty float through the doorway, getting stuck between them as Rico helps her get through by pushing onto her large butt, making her moan softly, successfully getting her inside to the living room.

Rico: Mommy Misty. You deserve my little peepee for giving me one of the best rides ever~.

Misty: *muffled giggles* oh, you're such a naughty boy, Rico. But I would love to have your peepee in my large butt. Would you like to give me your love~? *Smirks*

Rico: yes I do, Mommy. I'm going to take your clothes off and put my little peepee in your big butt~.

Misty: *muffled* good baby, I'm excited to feel you inside of me~.

Rico hugs her Inflated butt cheeks, rubbing them together that made her moan more, feeling him taking her shorts off to reveal her large cheeks and her wet, inflated pussy. He then takes all of his clothes off, lining up his small member between her folds, penetrating her, and slowly thrust in and out of her, moaning to feel how tight her whole is for his member. Misty was panting, flapping her puffy hands to feel him pumping her gently.

Misty: *muffled moans* oh yes, baby. Right at a good spot~.

Rico: my little peepee feel so amazing in your big butt, Mommy Misty. It gets me excited to fill you up~.

Misty: *muffled* keep going for me, baby. I really need all of your love~.

Rico: *giggles* good, Mommy. Now, enjoy my little peepee in your big butt and enjoy this moment. I'm going to release all of my love for you right now~.

He 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. Misty 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.

Rico: *panting* that felt amazing, Mommy Misty. I really had a lot of fun with you~.

Misty: *muffled* good boy. I'm glad you had a lot of fun with me~.

Rico: want me to play with your large boobies? I can put my little peepee in your mouth if you wanna taste it~.

Misty: oh yes, baby! I would love you to do that for me~.

Rico chuckles, hopping onto her Inflated breasts, playing with them to make them squeak and creak that made her moan softly due to how sensitive she is while inflated. His member was close to her plump lips, giving her a sign to start licking and kissing it. Misty kidd the tip of it, moaning more longer and lustfully to feel him teasing her erect nipples, causing her to lactate milk. She was in a bliss kissing, and tasting his little peepee while enjoying being his big blimp at the end of Airborne August.
