Marina (Sales Office Lady) is under a lot of stress due to work pressure. At times like this, I remember an old man I dated when I was a student. The SM training I received from him. He was tied up with barbed wire and played with his immobile body. Such masochistic habits were revived…. Marina went to see him at that time and asked for training. For the first time in a long time, she was immersed in masochistic pleasure, but Marina was still not satisfied and secretly asked a professional trainer for more intense and dangerous training. The masochist accelerated and fell into deep and dark pleasure. I couldn't turn back... ＃Yoro P
