Back to where with Rico giggling, seeing Belle swelling up with air, her cheeks puffed up cutely and her dress was getting lifted up, exposing her white bloomers. She looks down at him, rubbing herself to see that the swelling isn't going to stop anytime soon.

Belle: *muffled* oh dear, I'm swelling up more bigger. I feel really full with all of this air, baby.

Rico: hehehe. I can give you some belly rubs if you like? I can make you feel better~.

Belle: *muffled* sure, Rico. Rub my belly, please~.

Rico giggles, rubbing her swelling belly, hearing her soft moans and sighing in relief while she gets a lot more bigger and spherical. Belle's arms and legs sucked into her body, flapping her hands in her divots, and rocking slowly on her swollen crotch that's touching the ground with her feet barely touching the floor. She moans softly, feeling her body is now almost done inflating.

Belle: *muffled* mmmph... Mmmmph~...

Rico: so round and big. You're almost done swelling up, Mommy~.

He walks back a bit to see her now stopped inflating with air, finally becoming a large ten feet balloon woman, hearing her muffled moans of pleasure while rocking back and forth on her crotch. Rico touch her belly, smiling and looking up at her, excited to have a lot more fun with her. Belle tried to look down at him, but couldn't due to her inflated body covering her view, but she can feel him hugging her belly.

Belle: *muffled* wow. I'm so round and full of air like a balloon, Rico. This feels really good~.

Rico: I know right? You're really cuddly for me to cuddle on a lot. You look amazing as a balloon, Mommy Belle~.

Belle: *muffled* aww, thank you, sweetie. Since I can't move or do anything, how about you can roll this balloon around~.

Rico: sure, Mommy. I can do that for you. Try not to get dizzy~.

He put his hands on her butt, rolling her around in the library while bouncing on her body like a bouncy castle, hearing her muffled giggles. Belle was enjoying him playing with her inflated body, loving the feeling of him rolling her around, moaning softly to feel him now touching her big, inflated butt, pulling her bloomers down to get her fully naked. Rico gently put his small penis between her cheeks, thrusting in her as he feels her tightness wrapped around his shaft.

Belle: *muffled moans* oh my, Rico. I didn't know you had it in you~.

Rico: yeah, hehe. I love doing this with you a lot, Mommy Belle. Your butt is really huge and amazing~.

Belle: *muffled* it really does feel good when you do that. Keep going for me please~.

Rico: you got it, Mommy. Enjoy me playing with your big butt from behind~.

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. Belle 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.

Belle: *muffled* ohh... so good, baby. Fill me up more~.

Rico: *panting* yes, Mommy. Let me fill you up until you can't take it anymore~.

Belle: *muffled* so small and naughty. You're such an amazing little charmer, Rico~.

Rico: thank you, Mommy. Here it comes~.

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

Belle: *muffled* wow. This was actually really fun, Rico. I didn't expect all of this happen today~.

Rico: I really did enjoy this with you too, Mommy Belle. You're a really cool balloon princess, especially with you getting so turned on~.

Belle: *muffled giggles* at least I'm still beautiful being a balloon, baby. Wanna kiss me more~?

Rico: *laughs softly* yes, Mommy. I would love to kiss your plump lips more~.

He leans closer to her plump lips, feeling her giving him a lot of kisses all over his face and lips in a deep kiss. Belle sigh in relief to see him bringing the book back to her, cuddling on top of her as she continues to read it more to him while being his big, cuddly inflated princess.
