2. Mythra from Xenoblade (#19) 🥈
Pyra in the kitchen preparing a milkshake for Mythra, as she blends the milk and ice cream together, she then takes out a small hourglass shaped bottle and pops the lid. Pyra then pours a drop of her secret ingredient and stirs it into the milkshake making it glow a bright pink while. She then puts a lid and straw on the cup, winking at the camera. It then cuts to the next scene with Mythra sitting up and putting on her pantyhose as Pyra walks in and gives Mythra the milkshake patting her shoulder before leaving the room. Pyra then giggles to herself outside the door. The scene cuts back to Mythra as she picks up the milkshake and takes a sip, she grins as she enjoys the taste of Pyra's new beverage. Her chest then pulses and begins to slowly expand. It then stops around a basketball size. Mythra is pleasantly surprised by this revelation as she takes her new drink and places in her cleavage using it like a cupholder as she continues to drink it she then feels up her chest as it grows even tighter, squeezing her cleavage in her window before the camera cuts to her ass and thighs expanding growing extremely tight around her panties before reaching roughly double her previous size in both her front and rear which then tear/pop her panties which causes her to jerk in surprise. The camera cuts back to her cleavage as the drink slides back and touches her core crystal. Which then glows causing an overwhelming pulse to tremble in Mythra's assets which surge in size. Her pantyhose begin to tear small holes and her top begins to tear in the middle leaving her chest exposed as it shakes and sloshed around with her dress torn open. She continues expanding as the camera zooms out to seee Mythra filling up the entire room with her assets. Pyra then squeezes into the room and climbs on top of Mythra's chest, smiling as her plan worked.
Briefly: breasts -> +butt (expansion)
3. Zhu Yuan from Zenless Zone Zero (#3) 🥉
Zhu Yuan went on a patrol mission into Hollow. After some time she found a strange big Ether Crystal that was never seen before. She knows they tend to corrupt people but she came closer to inspect it out of curiosity. She slipped on some rubbish and fell on it with her boobs, she quickly backed off but after some delay it caused them to grew big enough to snap her shirt while revealing her black bra with pointy nipples seen trough. She is shocked at first but it was so much pleasurable that she decided to rub it with her belly. Again after she finished rubbing it, she turned around and after some delay her belly slowly grew bigger than her breasts. While it grew it stretched the belt and much later snapped it. Addicted to how it felt she went with her ass next and rubbed crystal with lot of up and down movements. (Her pants were latex-like so her butt made extra squeaky sounds and they were more durable.) It started to grow slowly at the beginning, then after some time it went faster and later her thighs joined in too. (Crystal is semi x-rayed to see butt clearly.) When her panties became visible through pants they just slowly stretched more and more like a string. (Because of durability pants became more semi-transparent as they stretched.) Totally lost in pleasure and without thinking straight anymore she just absorbed trough rubs more and more of the crystal power. After her ass grew big enough, she slapped her huge ass so her pants went into shreds but panties remained intact. Zhu's ass and belly grew (belly grew at much slower rate than ass) with each move and after some time, she cummed and her growth ended by absorbing the crystal completely, with her being at least mansion sized, with butt being enormous compared to rest, belly being huge and boobs much smaller than belly but still big. (Her arms and legs swelled a little too but every body part is clearly definied.)
Briefly: breasts -> +belly -> +butt (expansion)
