In the park where it's a normal day with Rico playing with some Marvel action figures in the sandbox with the Avengers saving the day until he saw a portal opening in the playground. The green portal shows a tall woman with long, black hair, green eyes, and wearing a black and green bodysuit with a cape, and she's wearing a crown with horns. She looks around, catching her eyes on Rico, walking in the sandbox, and steps on the Thor action figure.

Hela: what is this place? You there, kid. What realm is this?

Rico: it's the park... who are you and what are you doing here?

Hela: I'm Hela, the goddess of death and the firstborn of Odin. I was banished here for trying to take over the throne in Asgard, but my damn father stopped me. Mind if you show me around your world?

Rico: *nods* sure, Hela. I'll show you around. My name is Rico. Come walk with me.

He holds her hand, leading her down the park where they talk for a while as Hela tells him stories of her life in Asgard and the Nine realms. Rico was amazed to hear her stories as he had an idea to make her happy by giving her a gummy from his pocket. Hela takes the gummy from him, examining it and put it in her mouth, chewing to taste its lemon flavor, gulping it down.

Rico: do you love the gummy, Hela?

Hela: it does taste amazing, I gotta admit. I never had these in my home.

Rico: nice. The cool part is that the gummy is going to expand your body all big and puffy once you consume it.

Hela: huh?

She look down at her belly that's inflating with air, stretching out her bodysuit along with her butt and thighs expanding. Rico giggles, enjoying seeing her inflating a lot more bigger, hugging her Inflated belly, and felt her breasts expanding in his face, smothering him. Hela blushes to feel her arms and legs expanding, spreading out as the inflation stop, becoming semi inflated, and giving Rico a big hug, cuddling with him.

Hela: by the gods. This actually feels really nice, Rico~.

Rico: pretty cool right, Mommy Hela? You're now a big, puffy goddess. It really fits you so well~.

Hela: *chuckles* that's very sweet of you, baby. How about I'll carry you in my arms and you can lead me to your kingdom for some entertainment~. *Smirks*

Rico: sure. Cradle me in your arms, Mommy~!

She bends down a bit, scooping him up in her Inflated arms, keeping him close to her large breasts while she waddles down the sidewalk with her inflated body wobbling a lot and her butt bouncing. Rico looks up at her, feeling her giving him lots of tender kisses, putting his hands on her large breasts, squeezing them a bit to make her giggle and moan in pleasure. Now at home after a fun walk, Hela bends down, showing him her inflated butt that's wobbling in front of him, feeling him groping her cheeks and gently thrusting his member inside of her wet folds that made her gasp a bit and bit her lip to feel him inside of her.

Rico: for a goddess of death, you're really amazing with your big butt, Mommy Hela~.

Hela: *panting* oh damn! You really making me feel so good, Rico. I really loving this so much~.

Rico: good, Mommy. I'll keep filling you up more with my little peepee~.

Hela: keep going for Mommy. Your goddess needs more pleasure~!

Rico continues to pound her more, feeling her large butt bouncing on his body, squishing him against the couch as he reaches to play with her inflated breasts, teasing her perky nipples that's getting hard, leaking milk on the palm of his hands. Hela's moans grew louder, having her tongue sticking out, panting due to her inflated body being so sensitive, getting close to her climax that's going to erupt like a volcano at any moment.

Hela: oh yes, baby. I wanna feel a lot more inside of you. Keep playing with your inflated Mommy~.

Rico: yes, Mommy Hela. I would love to taste your your big boobies after I release all of my love~.

Hela: let it all out for me, baby. Mommy need you deep inside of her~.

Rico: oh... this is so amazing~...

He thrust in her a lot more faster, teasing her inflated clit that made her eyes roll back in her head, seeing her now squirting all over him as he finally release his seed, filling her up completely. Rico taste her juice, slowly getting out of her, and cuddles on top of her Inflated belly to suck on her nipple for her milk. Hela panting from their taboo, hugging him tightly in a warm embrace, patting his head gently as she continues to nurse him.

Hela: you did very good, baby. Mommy will feed you milk~.

Rico: thank you, Mommy Hela. I really had so much fun with you. You're really sweet for a goddess~.

Hela: *chuckles* you're welcome, Rico. Mommy is happy to make you so much better. I'm now your goddess of blimps. Let Mommy take care of you~.

Rico: ok, Mommy~.

He continues to suckle on her nipple, tasting her sweet and creamy milk while patting her inflated belly like a drum, and groping her other breast, switching to her other nipple to suck on it. Hela panting more, getting turned on to feel him sucking on her more, rubbing his back as she loves her role of being his big, balloon goddess of blimps.
