Join Rin-chan as we delve into her oral world, where she claims to brush her teeth thrice a day. However, her negligence becomes evident as she leaves a missing filling unattended for three months. We discover an impressive full crown on her upper left 5th tooth! With the corresponding tooth on the upper right left neglected, both sides seem destined for full crowns. To teach her a lesson, we playfully apply cold water and delicately probe with tweezers. Let this be the catalyst for Rin-chan to take control of her oral health. Explore the teeth fetish as Rin, 31 years old, embarks on this thrilling dental adventure.
