Strong-willed son's wife Saori. Before I knew it, I began to fantasize about having an affair with my son's wife in my head. Enjoying being restrained and unable to move, going into the bath together and using the whole body to serve, raping the daughter-in-law who was frightened by the slovenly SEX with her son while he was sleeping, etc. While doing such delusions. I couldn't tell the difference between fantasy and reality...
