Yvonnette got a hook up from a close friend on a post workout rehydration formula that was in development. It hadn’t reached the anthro testing phase but it sounded too good an opportunity to pass up.

So after at round of cardio and a light full body routine it was time to take a swig as she started her cool down. The formula acted fast. First thing the trim wolfess felt was a reincarnation that left her feeling like she was ready for another round. Next she saw the definition in her form become more and more pronounced. Even her height received a boost, her skeleton expanding as it prepared itself to support the power it was about to host.

And as fast as she went from trim to toned, Yvonnette’s muscles continued to harden and expand to male body builder levels of ripped. Every dimension had doubled in a matter of moments with muscle groups on clear display.
