It's been almost a year since I started dating her... but actually, I've been having sex with her mother without her knowing... It all started about a month ago...

As we spent time alone together, I felt a little uneasy, and the atmosphere between me and my mother gradually became more and more like a man and a woman... and we had a forbidden encounter without her knowing...
