Shirley was wearing an iron collar around her neck.The collar is connected with two iron chains and fixed on the frame.And she was handcuffed and shackled.A rope suspended her hands.The trainer took off her clothes.He would write on her back and let her guess what it was.Whenever she guessed wrong, he took out the electric massager and shocked her back and ass.Because she answered too many wrong questions, he pinched her nipples as punishment.She kept screaming and moaning.Then he caress her body as a consolation.
