Claire's Edging Exam: An Appointment with the Chastity Doctor (Kinky Medical BDSM Erotica #1)
Marisa McCoyle

Fortunately, her new doctor is a handsome man with warm, clever hands. Unfortunately, he seems to take joy in turning her into a locked, gooey mess.
He is ready to strap her down to his table for the most humiliating exam of her life. And the most maddening part of all? There’s no guarantee that he’ll let her have relief.
He wouldn't be so evil as to keep her deprived, would he?
This book contains 10,500 words of consensual BDSM medical play. It does not have a typical erotica “happy ending;” the content focuses on the sensual frustration of the submissive. (Book 2 has many, many happy endings for Claire.)
