Mistress Gaia had heard so many good things about her friend's boyfriend and especially how he was an animal in bed. She wanted to get a taste of it but she did not want it to be a long term thing and she never wanted anyone to know about it. So she had to come up with a way to execute it and she settled on hypnotizing the guy which she did easily and then they fucked like crazy before she used her mind fucking skills to erase or cloud that particular memory so that he never remembered. The secret stayed safe with her.
