Marina (Sales Office Lady) is under a lot of stress due to work pressure. At times like these, I remember an older man I dated when I was a student. The SM training I received from him. He was tied up with hemp rope and played with his unable to move body. Such masochistic habits are revived…. Marina came to him at that time and asked for training. For the first time after a long time of training, Marina was immersed in masochistic pleasure, but Marina was still not satisfied and secretly asked a professional trainer for more intense and dangerous training. The sadist speeds up and falls into deep, dark pleasure. I can't go back... ＃Yoro P
