Corliss’ jaws were aching. Her heart was thudding wildly in her ears, and her whole body was trembling. She could only see Amy from behind, but it looked as if she was really getting into sucking that c**k now. Her hands were clenched into fists, but she wasn’t struggling any more. It was quiet enough so that Corliss could hear the tiny grunts that Amy made with each stroke. The man she was sucking put both of his hands on her head and groaned. Amy’s hands unclenched. Her fingers wriggled briefly before she balled her hands back into fists. Then she made a high-pitched squealing noise of protest through her nose as the man groaned again. Corliss saw his hips jerk once, twice, three times, each jerk driving another nasal squeal from Amy. He groaned one last time. Then he let go of Amy and stepped away, zipping up his pants. Amy bent over, coughing and sputtering. The man holding her leash slapped her upturned ass, but it somehow looked as if he was congratulating her for a job well done.
