Unforgotten night (mm trans)

I am not sure all of my trans is exactly like the original story. If something is wrong, this is my bad.

TRIGGER WARNING!!!!!!!!!!!!
The story presents situations of violence, sex, sadism, and masochism. These actions may be offensive to some. I have been warned about this and if it is not your cup of tea please choose another story to read. All the credit goes to Yoe Nim, the writer of the novel.
