A stern mistress, skilled in the arts of BDSM, teaches her eager student the pleasures of anal play. She binds him securely, his body tense with anticipation. She chooses a large, intimidating butt plug, lubing it generously before pressing it against his virgin hole. With a firm push, it slips inside, stretching him deliciously. She fucks him with the toy, her hands expertly moving, drawing out his cries of ecstasy and agony.
