Goddess Nika wanted some of the money she knew this guy had but would never give her. She did not bother asking as she knew he would never give any of it to her. She did not want to borrow either as she knew the answer. That is why she chose to blackmail him and she did this after she had teased him and flirted with him and gotten him to wear a dick lock. She hid the chastity key and blackmailed him to open it.
