Goddess Nika did not want to go out there and try hypnosis unless she was very good at it. She did not want anyone to think she was an amateur. So she waited until she had become a pro before she did it to other people. In the meantime, she enjoyed trying her skills on her slave so as to test her own skills. And she never failed to find the need to improve and perfect her skills.
Goddess Nika knew this guy had what she wanted. And she also knew that he had a crush on him. Being a naughty girl, she used her hot body and her naughtiness to turn him on so as to distract him from what she intended to do to him. She used her hypnosis skills to get him to do what she wanted and that is how she succeeded in her mission.
Goddess Nika has always had a crush on her friend's husband. She wanted to nail him but she had to be careful about it. The mistress chose to hypnotize him so that she could fuck him and he would not remember anything about it. She teased him a little bit and used it to brain fuck him. Once she had gained total control over him, she screwed him and erased it from his memory.
Goddess Nika had asked her slave to remind her about an important thing she needed to do. However, the slave forgot and she missed doing the thing. She was angry as he had forgotten to do what she asked and hoped he would remember. She wanted to mess him up so she hypnotized him and then made him crazy and cruel things to himself which he wondered for days how they happened to him when he came to.
Goddess Nika was horny but there was no one nearby to put her out of her misery. The only person near her was a slave and she could not nail a slave. So she chose to make him as miserable as she was. She played with herself although without removing her clothes. She did it while her slave watched. He was turned on but she did not do anything to or with him.
