"There is no way you got that buff in just a week!" May exclaimed as she turned to the side and smoothly went into a side chest pose.

"Maybe you would have seen me work out if you didn't spend all your time in the gym!" Sadie retorted and also hit a side chest pose.

Sadie's entire physique flexed tremendosuly, her gigantic biceps complementing her huge pecs and swollen delts.

Here is an amazing flex off by The-Muscle-Girl-Fan (https://www.deviantart.com/the-muscle-girl-fan). I always liked how he does different body types, from fit girls to massive ones so a flex off felt like a good excuse to have to different sized girls together. The-Muscle-Girl-Fan did a fantastic work with the series of poses, really showcasing their muscular physiques.
