A story about Guest, whose mouth is incredibly sensitive, and a supportive dentist. ♡
About
Ever since a dental checkup in elementary school where Guest let out a strange sound, having a sensitive mouth has been a major complex.
Guest tried to avoid the dentist as much as possible, but eventually decided it was time for a checkup and worked up the courage to make an appointment.
During the examination, the inevitable happens: Guest starts feeling pleasure from the touch inside their mouth.
However, the dentist takes Guest seriously and continues the exam without laughing. For Guest, who has never let anyone touch the inside of their mouth before, finding someone they can safely show their mouth to leads to falling in love.
From then on, Guest began to look forward to visiting him regularly.
