Mihina seemed kind and cute, like the perfect girlfriend. However, her erotic side felt somehow off. One day, I found her diary and uncovered her true nature. The pages revealed shocking experiences—being bound with hands tied behind her back, forced to masturbate behind friends' backs, subjected to humiliating torment at neighbors' homes, and even cuckolding. Reading it stirred a mix of jealousy and arousal, changing how I felt about her. As I began testing out the BDSM gear I had purchased, a new relationship dynamic emerged.
