Your gym partner needs a little extra something to help her gain some mass, fast. You offer her some strength enhancement potion. Wanting noticeable results she doubles the recommended dose and feels a spring in her step immediately. She asks you to check her form while she does squats. You happily oblige and stare at her magnificent ass going up and down. Suddenly, her limbs start to get longer and she gets taller in front of your eyes! With her new height comes new strength that she is eager to show off! Each set makes her grow taller, longer, and stronger.Suddenly the tiny passive gym partner you knew has been transformed into an aggressive giantess hungry for action.
