[ Hello, I am the author of this immoral novel. First of all, I warn you that this novel is itself an R-18 novel and will contain quite strong genres such as incest, rape, strong sex and all kinds of immoralities that I can think of, except the 'NTR'. As for grammar and English, I may have some problems since English is not my mother tongue. So sorry if it is not to your liking.
And finally, I make it clear that "don't open ntr", since it is my most hated genre and I don't want to include it in this book or in my future books ] [ P.S: I am not the owner of the image, if you want me to delete it, send me a message and I will do it immediately ]
