In a regular afternoon inside of the mansion with Kirumi Tojo watching Rico, enjoying his mischievous behavior as she would place him on her lap, playing with his hair to make him giggle, hugging him tightly as she really does enjoy taking good care of him. Rico looks up at her, thinking about something they should do.

Rico: hey, Kirumi. I've thought about something we should try out and I don't know if you'll agree to this.

Kirumi: of course we can do something, Rico. You can tell me what do you have in mind?

Rico: well... I've thought about if you would like to be my blimp for me today please?

Kirumi: *blushes and smiles* oh dear, Rico...well as your maid, I can't deny your request. After all, I'll do anything to make you happy~.

She pat his head, carrying him in her arms as they would go walk out of the living room, through hallway as they would find a helium tank in one of the storage room, and a hose connected to it. After taking it back to the living room, Rico sets everything up for Kirumi to use it to expand her body really big for him, looking at her with a hint of mischief, excited for the ultimate maid doing this request.

Kirumi: you seem really excited to see me all big and puffy~. *Chuckles softly*

Rico: of course I am, Kirumi. I always love you inflated along with Mommy Kyoko and the others I've Inflated a lot. You'll be a good blimp for me to play with~.

Kirumi: you're such a naughty boy, Rico. I'll gladly be your personal blimp for today. Now, climb up on my back so you can enjoy the flight~.

Rico: yes, ma'am~!

He climbs up on her back, clinging her tightly as Kirumi would then put the hose in her mouth, turning on the helium tank, making a loud hissing sound with helium going through the hose, puffing her cheeks puffed. She felt her belly expanding, stretching out her dress and her butt and thighs inflating more bigger, feeling her panties now stretched out along with her body getting much bigger, floating from the ground as she moans softly. Rico bounce a bit on her back, enjoying to see her inflating for him that turns him on, seeing her breasts getting huge with her arms and legs getting puffy, taking the hose out of the mouth as he was happy to see her as his giant blimp.

Rico: now you're my big, puffy maid! You look so hot like this~.

Kirumi: *muffled giggles* thank you, sweetie. I'm glad you love my inflated body so much. Relax and enjoy the ride. You can play with me as much as you like too~.

Rico: that's really cool of you, Kirumi. I would love to keep you like this for a while~.

Kirumi: *muffled* I don't mind being a blimp for you, Rico. Let your blimpy maid give you a lot of love~.

Rico giggles, feeling her bouncing around the mansion, enjoying the ride, cuddling a lot more on her back, and groping her Inflated breasts, teasing her gently to make her moan softly. Kirumi blushes more, loving the feeling of being so vulnerable by her young master, feeling his small hands rubbing her inflated belly, and her huge butt as she wiggles it in front of him, giggling while floating around. Rico then felt her cuddling him tightly, giving him lots of kisses all over his face.

Kirumi: *muffled* mmmm, you're so sweet and naughty. this is so amazing, Rico~.

Rico: good, hehehe. I'm really having fun with you so much, my blimpy maid~.

Kirumi: *muffled* I'm glad you enjoy your fun with me. Let me kiss your face more. You deserve it~.

Rico: ok, Kirumi. Kiss me a lot more~.

Kirumi giggles, giving him more kisses, feeling him hugging her Inflated breasts, squeezing them together that made her laugh. Rico was so happy to play with his ultimate blimpy maid that really was enjoying his company to make her really happy after a long day of doing a lot of chores. Kirumi was also happy to make Rico really happy, thought to herself that she's his best blimpy maid for taking good care of him.
