While this is pretty hot in concept and execution...I have to ask why she didn't get an inconveniently big pussy from that. Not that that would be preferred...I just have to be "that guy."
@Evertide No, you go ahead and BE that guy, because this just doesn't make any sense. Concentration on either breast to make it bigger on its own, okay, fine. If that's what's established, then putting it between her legs SHOULD have just resulted in a comically puffy pussy. And why did she want to make herself taller anyway? Compare the lower angle on Milo on page 1 to Olive's profile on page 3 as she's reaching for the paper towels. The wand looks like it's just coming up to Milo's nose, and if we take away her added height from standing on her tip-toes, it looks as though the wand would come up to Olive's clavicle. Combine that with how almost every panel she's in is drawn very vertically and she fills up most of the frame as such, the very FORMAT of the comic itself implies a very appealing, modelesque sense of height already. Why would she want to be taller for him when she's already there?
