Blaze is probably closest to Volt's build actually; small bust; bottom heavy with some general fit figure to her. Amy is actually on the slight chubby for me-- being a bit down with the thickness in all the right places. Something similar to Argento's design for her. (2/??)
Tangle seems similar to Blaze in a way if not more fit than her with a slightly bigger bust. Whisper I feel like is the hourglass look but more balanced between both. Lanolin is Rouge build if not thicker in one or two aspects. (3/??)
Surge I feel like her clothing hides her figure but would be more fit/tone than the others but have a surprisingly bigger hip/bust/thigh/butt ratio than people think. Also, piercings for sure. Vanilla is just pure milf bod-- lets be honest here lol. (4/??)
