In this video, I'm wearing my shiny black leggings to do some yoga. I start on my knees with my buttocks taut and I gradually straighten up to stretch my buttocks in the air. The leggings mold my big buttocks perfectly. I have fun doing it faster and faster and moving my big buttocks. I try to twerk, but the position is difficult to hold. I feel my big buttocks moving in all directions and tossing to the rhythm of my movements.
