senior's girlfriend

She was introduced to me by my senior and said, ``She's a pervert who has a crush on me.'' She was my boss, who had just scolded me yesterday. Although I was surprised, I pretended to be calm and decided to continue drinking with the three of us. There, the drunken senior started messing with her and showed her what he was doing. That night, when I witnessed her masturbating, I threatened her and said, ``I'll show you that she's just a perverted woman, even though she's arrogant at work!'' and thrusted into her violently while she was sleeping.
