With a flex and a pose or two, Yvonnette admired her sudden gains. “Yeah, I’d say this stuff is working beyond expectations.” But she also knew it wasn’t done as a tingle in her veins announced the arrival of a second wave. Far be it from a growth muse to deny her changing body.

With a wide stance, the grey wolfess relished every second of it. Muscles expanded with every tensing flex yet their size would not deflate as they relaxed. Instead it would become the new baseline for the next swelling contraction to build from.

Layer upon layer. Size added to size. Power compounded upon power.

The show subsided as the formula finished dissipating throughout her body, it was abundantly clear just how much more of her body now exists. Broad feet and stalky tree trunks for legs to support and transport the font of mass above. Diamond cutting abs jutting forth as a set of solid bricks with every other supporting muscle group in her torso on full display. Back that flairs out and extends up to swallow up the thick cords in her neck. Beach ball sized shoulders broadened to provide the clearance required for the pillars of power that were her monstrous arms.

Good thing she stocked up on the extra strength elastic athletic gear.
