University professor is a profession full of unexpected personalities, and according to him, I'm apparently unusual too. This is Reina Mamiya, 38 years old. A full-time housewife and wife of a university professor, she has lived with her husband for ten years. Currently, they have no children and enjoy a marriage without interruptions. Her husband is surprisingly 63 years old, past retirement age. He was divorced once back in his student days and remained single, and she somehow began frequently visiting his home, eventually leading to their marriage. Reina became a graduate student instead of getting a job, continuing her research just to stay with her husband. In reality, she is highly educated and was raised as a lady, belonging to a completely different world than most. When it comes to relationships with men, she's only had a handful of experiences besides her husband, meaning much of her sexuality remains unexplored. It was within this kind of marriage that she began considering adult videos. Her husband originally had a strong sex drive, but as that diminished, he gave her permission to cheat. Though shocked and confused by this sudden turn, she found herself unable to resist the situation. Reina, you really are unusual after all!
