1. Iono from Pokemon
Iono has set up donation stream where viewers can pay to inflate her breasts or butt through two electrical currents in her butt and nipples connected to a rotom machine. First all the donations are for her butt. Iono squeezes her butt, surprised by how soft it feels. She then angles her butt closer to the camera and shakes it for the viewers. Soon donations start to come in for her breasts, causing them to grow too. Iono tries to show her curves off while the camera moves to a side profile view. Soon her butt grows larger than her body and the weight causes her to fall on her butt. The camera moves to focus on showing off her much smaller but still growing breasts. She moves her hands to her breasts, holding them up from below, presenting them and blushing a bit from how good it feels. She tries other ways to show off her breasts such as shaking them back and forth and bouncing them up and down. With so much focus on her breasts, the viewers start pouring all the donations into her breasts. Her butt stops growing and the rate of her breast expansion rapidly increase. The amount of electricity results in occasional pulses of growth. Her breasts quickly catch up to the size of her butt and continues to grow past it. The sped up growth causes more pleasure for Iono, blushing more and almost panting as she fills half the room and begins be pushed back. As she slides back she tries to hug what she can of her breasts, wanting to grow even bigger. Seeing how much Iono is enjoying this, the viewers increase their donations further, adding her butt back into the growth. With her butt against the wall, she starts filling room. The pressure begins to build up until she finally bursts out of the room. With the room destroyed the stream ends abruptly, stopping her growth at the same time. With her breasts still larger than her butt and unable to move, Iono gives a big grin, thinking about how she can go even bigger for next stream.
Briefly: butt -> +breasts (expansion)
2. Shiranui Mizuki from the Taimanin series
Shiranui is investigating a suspicious abandoned lab when she's taken by surprise by a mass of slime emerging from the ground, pinning her feet and glaive down! Unable to break free, another massive slime hangs down from the ceiling and stretches a tendril into her mouth! The slime begins acting like a giant pump, pushing a large volume of slime directly into her tits HARD, causing them to grow in a big, powerful pulse. She tries to hold her breasts back with her hands, but the slime continues to pump. The strength and immense pleasure of each pump makes it difficult to hold back anything as her huge boobs grow even more massive, her nipples bulging through her leotard as it slowly tears open. Her beautiful huge boobs soon burst from her suit, growing to completely cover her torso just as she finishes swallowing the entire slime. Stunned by her newfound size, she's once again caught by surprise as a second massive slime emerges behind her. This one starts filling her ass, pumping her up so hard that she's pushed forward and up with each fill. Shiranui tries and fails again to hold back her growing ass with her hands, struggling against an even greater level of pressure, especially as her leotard gets stretched into her crotch. Her ass grows until her leotard, barely a string now, snaps. The strength of the pumping and the weight of her assets finally proves too much to her and she falters, clutching to her glaive to stay on her feet. One last slime emerges below her, rising between her breasts and back into her mouth as the two slimes alternate between pumping her tits and ass. The slimes, now being squeezed between her boobs and ass cheeks, keep pumping back and forth as Shiranui grows and grows. Totally overcome by the feeling, she grows so big she outgrows the lab and the building comes down, until finally... she swallows the last drop. Shiranui is left totally dazed after being pumped up so big... she'll have a hard time explaining this to the girls back home.
Briefly: breasts -> +butt (inflation)

4. Rio Tsukasatuki Blue Archive
In a large laboratory, Rio decided to perform performance tests on her improved inflation machine. After completing the performance tests, she planned to conduct practical tests using a VR simulator. Rio operated the inflation machine using a tablet device and started it up. A hose shot out and stuck into Rio's buttocks, and the inflation machine began to pump. Rio's breasts began to inflate. She picked up the tablet device she had dropped and tried to stop the inflation machine, but her breasts inflated so much that she lost her balance and fell forward. She dropped the tablet device again, and the inflation machine could not be stopped. Her belly began to swell, becoming extra-large enough for Rio to sit on. Her buttocks also began to swell, becoming extra-large as well. After a while, her arms swelled, and her entire body expanded, becoming a blimp. Rio tried to remove the inflation machine's hoses by shaking it back and forth, but it wouldn't stop. Instead, the inflation machine entered over-inflation mode and continued to inflate, floating upwards and hitting the ceiling, getting caught on it. It continued to inflate, filling the rather large laboratory with Rio's body. Rio's body creaked, and she was on the verge of bursting. Just as she was about to pop, the inflation machine stopped. It was Toki who pressed the forced stop button. Rio praised the inflation machine's performance, but blushed at the sight of her inflated state.

5. Super Pochaco from Super Sonico
Super Pochaco is is wearing a white bikini and standing on a cooking show set in an empty film studio. Feeling hungry, she decides to blend herself a smoothie with the ingredients on hand, not realising that the blueberries she added were labeled ‘unfit for consumption’. As Pochaco happily drinks the smoothie, her belly turns purple and begins to push outward. Pochaco doesn’t notice this at first, as she cannot see her belly over her breasts. It is only by the time she finishes drinking the smoothie that she sees her purple belly poking out past her breasts, and a panicked expression falls over her. Pochaco is able to stop her belly from growing by wrapping her arms around her midsection, but that only redirects the growth to her hips, thighs and butt, turning them purple as well. Pochaco tries to exit the cooking set with her arms still trying to contain her midsection. Accidentally bumping and knocking over several things in the process with her wide, inflating hips. She eventually makes it to a doorway in the set, and is able to fit her torso through the frame. Her bottom half however is too wide to fit. She removes her arms from her belly to try to use them to push against the frame, but that causes her belly to quickly expand down to the floor. Pochaco tries her best to free herself from the doorway as the purple colour spreads to the rest of her body. Her arms and breasts also begin to inflate until she can no longer move, forcing her to give up on struggling and accept her fate as she realises that inflation feels quite nice, her anxious expression changing to something more joyful. The inflation spreads to every part of pochacos body as she grows to occupy the entire doorframe, with her legs and butt on one side, and her breasts and belly on the other side. Eventually she becomes so large that she demolishes the doorframe along with the entire wall. ow taking on a more spherical shape, she rolls back towards the centre of the set as she continues to grow larger. As Pochaco continues to fill the film studio, she knocks over all of the features in the cooking set, eventually outgrowing and completely destroying the set before her inflation finally stops.
