A stern BDSM instructor, armed with a hefty dildo and a length of rope, commands her student into submission. She binds her wrists and ankles, leaving her spread and vulnerable. With a wicked gleam, she lubes up the dildo and presses it against her student's tight, puckered hole. The student gasps as the instructor slowly pushes the toy inside, twisting and thrusting until she's fully impaled on the thick shaft.
