This is a very exciting video! A sadomasochistic master unties his submissive so that she can spread her thighs. With a vibrator, he annoys her clitoris and vulva to prepare her for the little program he has planned for her. He now lays it down on a wooden plank which is nothing more than a pallet. He spreads her thighs with ropes until she is in front of a sex machine. It’s a dildo mounted on a piston that will come and go quickly to pump her vulva. She has breasts that are going to explode because she is so excited and stressed by the situation. Personally, I loved that she keeps her heels high and that the guy comes to use his vibrator on her clitoris while the machine smashes her vagina. Excellent video once again!
