ドミナトリックスミストレス4月 - フリントストーンのジレンマパート1

A dear friend and fellow Dominant, Mr Flintstone, contacts me with a dilemma. His female slut was sent to slave school for training but has returned as bad as before. In desperation he turns to me to assist him in giving her the training she needs as well as giving a slut what she deserves.
