She lies down and brings her knees up, ankles to her sides and hands behind her head so that he has full access to her chest and her pussy. He teases her a little, stroking her pussy before he begins to spank it. Over and over harder each time, spreading her lips as he does so to be sure he gets her clit. Next comes the clamps, one on each lip and one on her clit. She moans but does not complain, as much as it hurts it also feels good to her. He applies some sort of clamp to her nipples, she is not sure what type, the pain is intense but again she does not complain.
