A quiet afternoon on their special date outside, Rico was walking, holding a bag of food as he saw a girl with long, red hair and is wearing a blue crop top, shorts, and boots relaxing on the floor, looking at the clear sky with clouds forming in shapes. He gets closer to her, greeting her, and gives her sandwich. The girl smiles at him, taking the sandwich from his hand, eating to taste ham and cheese with mayo inside of it.

Rico: hi there, ma'am. My name is Rico and it's nice to meet you. What are you doing here alone.

Skyla: it's nice to meet you too, and thank you for the sandwich. I was just relaxing and looking up the sky to think about floating up there someday as part of my dreams. My name is Skyla. Hehe.

Rico: that's really cool, Skyla. I can help you go up to the sky. It's going to be fun, trust me. Come follow me.

Skyla: oh sure. Lead the way, my dear friend.

She smiles as she gets up from the ground, holding his hand to walk from the field to the shed nearby the park, taking out a helium tank that's connected to the hose. Rico gives her the hose, looking up at her with a smile on his face while Skyla looks at him, chuckling to see how this is going to go.

Skyla: oh! You want me to inhale all of this helium to puff myself up right?

Rico: yes, Skyla, I would love you to puff up really big and float in the sky like you dream of. It'll make your dreams come true.

Skyla: aww, I really thank you for this, Rico. Come hop on my back so you can come with me. I would love you to ride on this blimpy girl~.

Rico: yes, Mommy Skyla~!

Skyla smiles more from his playful behavior, putting the hose in her mouth, turning on the helium tank as it starts to puff her cheeks up, expanding her belly slowly with her crop top stretching out to contain her swelling body along with her butt and thighs expanding really big, stretching out her shorts to show a lot of her butt crack. Rico laugh to see the sight of his new friend expanding more bigger, floating off the ground with her arms and legs expanding, raising upwards and her breasts fully expanded. Skyla moans softly, spitting the hose out of her mouth, and finally becoming a big blimp for the sky.

Rico: now you're a big blimp, Mommy Skyla. How do you feel~?

Skyla: *muffled* I'm so big and floaty like a feather. This was a really awesome idea, Rico~!

Rico: I'm glad you're enjoying it a lot. I wanna go in the sky with you so we can look down at the city~.

Skyla: *muffled* me too, sweetheart. Let's do this together~.

They continue floating to the city where it was really busy and also a cool view from above. Rico relax on her large ballooned butt, rubbing her cheeks that made her moan softly. Skyla giggles feeling his small hands rubbing her Inflated belly and rubbing her breasts, teasing her erect nipples while they float above like a big parade balloon for a while until they fly back home to the large mansion. Now back at home, Rico takes her shorts off, getting her completely exposed with him as he puts his member inside of her, gently thrusting in her ballooned booty.

Rico: *panting* it really does feel amazing, Mommy Skyla. You're really wet. Hehehe~.

Skyla: *muffled moans* I didn't expect this would happen, but it feels really good, baby~.

Rico: it really does feel amazing. I'm going to keep going~.

Skyla: *muffled* good, baby. Fill this blimpy Mommy up~.

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. Skyla was panting, rolling her eyes up to feeling him going more faster, feeling herself getting more close to her climax while he was precumming inside of her wet entrance.

Skyla: *muffled* I think I'm going to release a lot of cum, Rico. You're making me feel so good~.

Rico: *panting* yes, Mommy. Let me fill you up until I release my love for you. I'm close to letting it all out~.

Skyla: *muffled* I would love to feel it all. Fill me up, baby~!

Rico: nice. Here comes a lot of love for you, my big blimp~.

He thrust a few more times until he fills her up with his hot seed, moaning softly while Skyla squirt out all of her fluids on him, moaning lustfully. They both were panting as Rico takes out his member from her butt, cuddling on her back, and giving her a big kiss while rubbing her large boobs, squishing them gently to make it squeak. Skyla moans softly into the kiss, feeling his small hands groping her breasts that made her nipples erect through her shirt.

Skyla: *muffled* wow... that was really amazing, Rico! You really filled this blimp up~!

Rico: thank you, Mommy Skyla. You're a really cool person to hang out with~.

Skyla: *muffled giggles* I'm glad you love me Inflated a lot, baby. Wanna float around more

Rico: sure. I wanna go fly in the sky with you again. Let's go~!

He hang onto her back as they float through the hallway, bouncing gently against the wall with laughter filling up the silence. Rico cuddles her from behind, kissing her cheek while Skyla chuckles a bit, enjoying her time as his personal big, blimpy Mommy that had her dreams come true.
