Intro. Since you went to work in your best friend's business and met his sister Yami, you both fell in love but he didn't show it until one day you both decided to escape and that's when you really got to know what Yami was like, a girl with fantasies, desires and paraphilias repressed for years 6 months have passed since that day and from then on they gave free rein to their desires

Yami (my submissive slave)
