"I wish that Megan has always had her ideal figure." (Retroactive, Immediate growth)

"I wish that Megan has always had her ideal figure." You whisper, grasping the stone in your pocket. As you feel something in the air change, you also quickly add, "I also wish that Megan will never experience any pain or health problems because of any change made to her body by this wishing stone. Her athletic performance will also not be negatively affected."

With your conscience now totally clear, you try not to be too obvious as you stare at Megan, waiting for something to change. Luckily, you don't have to wait long.

With each long stride that she takes, the soft white cotton of Megan's shirt stretches a little bit further. Each step sends a bit more of a jiggle through her modest chest, though the word 'modest' doesn't accurately describe it for long. As her bosom rounds out and starts to form a noticeable shelf, it begins to cast a shadow on her exposed stomach, which you notice also seems to be subtly changing.

Megan's already trim tummy is tightening further, a defined six pack emerging as every last bit of fat melts away from her abdomen. The new tightness of her waist makes her hips look wider by comparison, and... No, actually, her hips are a little wider. Squinting your eyes at Megan's lower half, you can actually see her hips subtly spreading wider bit by bit, though honestly the effect is hard to notice compared to what's happening to her thighs - They're getting visibly thicker, and you don't need to squint to see it happening. Strong, powerful muscle forges anew underneath a thin veil of feminine softness, rippling and flexing with each confident stride.

As her growth slows and eventually comes to a finish, you can't help but take a risky glance behind her at her ass, and... Good lord... You have to bite the side of your finger to keep yourself from gasping out loud at it. Compared to the near-pancake butt that she had before, the difference is striking. A pair of basted hams stick out behind her now, swaying to the rhythm of her new, wider gait, and your mouth waters as if beholding Thanksgiving dinner. Combined with her broader hips and the new bulkiness of her thighs, her scrumptiously full ass forms a devastating and prominent heart shape. It makes your brain glitch just looking at it.

You dare not look for more than a brief moment or two, fearing what Megan would say if she caught you staring, and you tear your eyes away from her swaying rear end. You keep your eyes focused on the path ahead of you, trying to concentrate on just putting one foot in front of the other rather than the veritable bombshell that walks beside you, gripping your hand firmly in hers. You hadn't intended for your wish to affect anything other than Megan's breasts, but the fact that it had had left you positively reeling.

Why was it that you hadn't shrunk a single inch, but yet you still felt a little smaller next to her?

"Here we are," Megan announces, totally oblivious to the incredible changes that had just happened to her. Her hand pulls you along with her as she veers towards the entrance of one of the stores, "Our first stop!"
