At 23:00 PM, When Her Husband Is Sleeping, Yuka Onosaka, A Big-breasted Female Teacher With Great Technique, Brings Her Student (M-man-kun) In At Night For Sexual Processing And Gently Boning Him.

A beautiful female teacher invites her favorite student to her home under the guise of 'extra lessons.' Lured by the popular teacher, the student enters the door with anticipation. But at night, while her husband sleeps, she reveals her true nature with a sinister smile. In the basement, even when the student reaches his limit, he is treated as a tool for her sexual gratification until she is satisfied—a secret time hidden behind the facade of a peaceful daily life.
