I work in a factory. When I talked to my colleagues about my dissatisfaction with my sex life because I couldn't express my sadistic desires to my girlfriend—because I didn't want her to hate me—Ningning, a part-time married woman, overheard. So… when we were alone at a party, someone told me I had masochistic tendencies and that our sexual orientations were compatible, so we went to a love hotel for some excitement. At work, the taciturn Ms. Ningning let me treat her like a sex toy, saying things like, "You want to do anything to me…" arousing my sadistic tendencies. I strangled her, bound her, had sex with her, and did whatever I wanted to her. She suddenly transformed into a masochistic, devoted wife, allowing us to release our hidden desires.
