The lustful sister relieves her daily stress by teasing her younger brother's cock. Today, she starts with face riding, then stimulates his thick shaft with high-speed scissoring, and rides him cowgirl-style, wildly bucking her hips like a rodeo. Though her brother is a total masochist, he occasionally wants to tease his sister back—using toys and dildos to repeatedly break her down, pushing her to orgasm after orgasm without letting up. In the end, the dominant sister sinks into deep submission, becoming a full-blown masochist who begs her brother for even harsher torment.
