"Alright, I'll go with the Pear upgrade next." Samus said, selecting it from the computer. The last two upgrades were odd, but useful, and she was curious about what something called a "Pear upgrade" would do. She took the chip, and saw that it was for her zero suit, and complied, removing her armour and plugging it in.
Samus began to feel a strange grinding feeling in her groin, and looked down to see that her hips seemed to be moving apart! Her hips slid apart, an odd sensation to Samus as they approached the width of her shoulders, and then passed it, giving Samus an extreme pear-shape figure. After that, Samus noticed that her rear end felt
Fuller than usual, and looked around to see that expanding too! Her normally average ass was growing in size and volume, swelling to match the growth from normal, to if someone had attached melons to her rear, each cheek larger than her head.
Samus have a small gasp as she began to sway backwards, her centre of gravity off as she toppled onto her newly padded ass, and rather than feeling any pain, felt merely a small thwap from the impact. She pulled herself back up, and walked over to a mirror, her hips giving her a large sway, accompanied by copious amounts of jiggling. Samus looked into the mirror, turning as she took a look at herself.
"Alright, how is this supposed to be useful again?"
