O-san (pseudonym). A gentle and cute type of office senior who is popular among colleagues. She seems to lack affection from her husband and keeps inviting me during business trips. She's beautiful with a great figure, so there's absolutely no issue on my end... It's a familiar scenario, right? Usually it's like being stuck sharing a room with an unwanted superior, but this time it's the opposite. Gradually, you'll find yourself drawn into her charm and seduced by her allure.
