Sarah and Emma lied to this guy that they were turned on by inflicting pain in men and the men enduring it. They lied to the guy that if he endured it, they would fuck him. The guy was dying for a threesome and since he was not loaded and he was not smooth with the ladies, this seemed his best shot of trying a three way. The mistresses used their high heels to trample his fingers and hands while he endured the pain.
