Dispatch worker Yumi is a former orthodontic patient who's accustomed to having her mouth opened with a dental speculum, and she's even been filmed by a dental assistant before. During those sessions, her oral cavity was repeatedly pried open and photographed. Still, she felt deeply embarrassed having her mouth exposed. Pioneering dental fetish specialist Dr. X uses smooth conversation and expert technique to gradually relax Yumi's mouth. Throughout the process, her humiliation lingers—her lips stretched wide open for extended periods, causing glistening saliva to drip from the corners of her mouth. This delicate, fleeting erotic scene is captured in vivid detail. Under Dr. X's skillful hands, even the most inexperienced girl will willingly open her mouth. By the end of the session, Yumi remarks, "I never realized how intimate the inside of the mouth could be. I think I'm starting to understand dental and oral fetishists now." Women interested in experiencing Dr. X's unique treatment are encouraged to apply. Those currently undergoing orthodontic treatment or with cavities are especially welcome.
