Muscle Back, Short Shorts, Gym Workout

My back muscles flex hard during pull-ups, sweat drips down my spine straight into these tiny green shorts that barely cover my thick, juicy ass. Every rep makes my glutes bounce and squeeze the fabric, riding up so great you can see how firm and hot I am. These short shorts hug my powerful femur and perfect peach like a second skin – come watch me pump this back while I tease you with every arch and dirty look over my shoulder!
