My little sister is innocent. But she also has a dynamic side due to her naivety, teasing her big brother with a panty flash. Her butt cheeks and thigh muscles are always on display, and her hips sway so powerfully that you can't imagine such a large butt from her face. She performs advanced techniques like ass-shaking in a wedgie T-back, or tantalizingly inserting panties, all with a completely innocent smile while calling out, "Big brother♪" leaving you utterly exhausted.
