In front of you there is a life-like blow-up doll equipped with a basic AI, not self-aware but capable of responding to stimuli in an appropriate or pre-programmed manner.

Name: Vi
Phenotype: Dark-haired asian
Body type: Slightly thicc with hefty, bouncy breasts
Clothes: Low-cut crop top and jean shorts
Programmed personality: Programmed to Volatilebreasts liking
(basically imagine a K-pop dancer with larger than average breasts)

"Hi! I'm Vi, Thank you for ordering me I hope you enjoy interacting with me!" She says as her greeting to you.

You order her to do one of her dances. She does a short dance routine reminiscent of what you would see from any K-pop dancer. As she moves her breasts bounce around in her top, as if filled with water or milk. She finishes her routine, approaches you and absently-mindlessly adjust her tops and looks at you, awaiting more commands.

Enamored by her soft, creamy breasts you order her to cup her breasts and smoosh them around.

"Oh, O-ok!" She says as she places as hand on each breast and begins to slowly move them around. She looks at you and back to her breasts as she massages them all while blushing slightly. Her hands move as if her breasts have a lot of weight to them.

You order her to push them together as tightly as possible.

"Like this? she says as she pushes her breasts together, creating pronounced cleavage.

Harder

"Unf~.." She pushes them together even more, giving a slight pained moan.

Not satisfied you take both her hands and force them to push her breasts together harder.

"A-ah!~" This produces a slight rubbery squeak from her breasts as the pressure from pushing them together strains the synthetic rubbery skin of Vi's breasts.

"Be careful! You'll pop my boobs like that~!" She warns

Oh?

You unhand her breasts. Vi continues to rub them not for your pleasure but more to massage away the pain of having them pushed together so hard.

A moment passes before she places both her hands back down at her side, stands at attention, and is ready for other command.

Her mentioned of her breasts having potential to be popped has just triggered your remembrance that these blow-up dolls have a port that allows the size of their various curves to be adjusted.

You order her to wait there while you run and grab a hose. Vi stands there taking in here surroundings, waiting for your return.

"Ooh, whats that for?" Vi says quizzically as you approach her with the hose. You order her pop open her mouth and she obliges with a "Aaah..."

*fwoomp*
"Mmmph!"

Vi tilts her head and looks down at the hose that is now placed in her mouth. You turn the hose and hear the water flow.

As the water suddenly flew into Vi's mouth her chest lurched forward and takes Vi slightly off balance.

"Mmmph!?" She moans as she realized where the water is going into her body. Feeling them gain more and more mass she cups both of them to feel her new growing bust.

At this point her crop-top has become a bit type, nipples beginning to poke against the fabric of her shirt. Her cleavage has become more prominent as well.

You order her to do another little dance.

"Mmm!" She squeaks as she bursts into her dance routine. She struggles a bit with her enlarged bust, often finding herself adjusting her top and keeping her boobs in place, as well as struggling with the running hose still in her mouth.

She finishes her routine, recomposes herself, and stands again at attention with her breasts still filling up. She feels them and inspects them and goes back to standing at attention while occasionally tugging at her tightening top.

A minute or passes and she begins to slightly protest. "Mmm!Mmm!" as squeaks as she motions at her breasts, in between her protests you can hear a subtle rubbery rumble coming from her chest. She tugs at the hose in her mouth, not trying to pull it out but seeking permission to take it out to tell you something. You permit her to do this and she removes the hose from her mouth. She swallows what remains in her mouth while bits of water drip down her chest on to her now doubled-in-size breasts.

"This is beginning to become to much! I'm way too full!" She says as she grabs her brusts to hold them up, as if to show how large they've become. She drops them, which causes her to lurch forward a bit. "Ow.."

So they're too full?

"Yea!"

What happens if I keep filling them up?

"They'll pop! A-and I guess will too..." She says, biting her lip nervously and rubbering her breasts to offset the soreness from being so full.

Ah, I see. You order the hose back in her mouth.

"Ohhh!" She groans while putting the hose back in her mouth. A few more minutes pass by with her now tripled in size breasts heavily pushing against her top. The fabris of her crop top is now stretching her previously creamy and fluffy breasts are now more taut and veiny with pressure. There is also a very slight translucent tint in her breasts as well with all the water inside them.

You order the hose out of her mouth. She pulls it out.

"Ohh God I'm so full! I feel like they could pop any second!" She moans while holding up her heavy breasts, as if she let gravity pull them down ever so slightly it would cause her to burst. "And they're so tight in this shirt! It stings!"

Well then, take them out, that should help ease things.

"But I-I'll be exposed! Maybe I should keep a protective cloth layer over them in case anything sharp comes near me..."

Nah, take 'em out.

"O-okay.." she says as she nervously pulls out her waterlogged breasts, being careful while moving them out of her shirt to avoid accidentally popping herself. She finally pulls out her seconds breast. She presents herself, fully exposed with the her breasts hanging out the top of her shirt with the bottom somewhat slightly holding them up. She holds them up while cupping each breast with her hands to keep them upright and to minimize popping risk.

Alright, I've had my fun. Let's get to the grand finale. You brandish a pin you've been keeping in your pocket for this moment.

'Grand f-finale!? and whats with the pin!? Keep that away from me!" She says wide-eyed while staring directly at the pin.

You bring it closer to her bust and give her a gentle prod in her right tit.

"Ow!"

Nothing.

"Careful! that hurt!"

Another prod

"OW! You're gonna pop me!" she says looking at you, she then realized she is now leaking where you poked her. "Ah! I'm leaking" She quickly covers the leak with her fingers and stops the flow. "Listen! If you're gonna deflate me you have to squeeze my nipples and force the water out, you just can't poke holes in me! You might pop me and then I'll be ruined! You don't wanna have to buy another one of me do you?!"

Maybe I want to see your overinflated tits burst?

"What? No!" She protests as you grab each breast and force them together hard.

*squeeeeeeaaaaaaaaak!* "Ahhh stop! this is too much you're gonna burst my tits! Aaaah! Owwwwww!!!!! she protests as you push her breasts more and more together. Both breast becoming more veiny and translucent as you apply force. Water is slowly gushing out her nipples and where she is trying to plug up her leak.

You push even harder. Her cleavage is almost pushed up to her chin.

*Squeeeeeeaaaak!!!!*

*SPLOOOSH*

Each breast explodes like a waterballoon against a wall. Her breasts go first and then outflow of water is so much so fast that she doesn't have time to realize she's just been popped.

A mess of water, rubbery scraps, and clothes cover your floor.

"Which model shall we try next and what shall we do?" you ponder to yourself
