URVRSP-267 [VR] [8K VR] An ``adult'' sweet and sad private lesson taught by a neat and easy-going older sister who uses her body in the bath in her room.

She is a young lady who attends a prestigious university, the daughter of a wealthy family, and a boxed girl who attended a girls' school until ● school. Because she is naive about the world, she is very curious and is close to the opposite sex, but she has no experience with men. Rei, who started working part-time as a private tutor to study social studies, became the ``teacher'' of a boy she had known since childhood who was aiming to take university entrance exams.
