This book is of sanscest sins. If you don't like it please don't continue, as for those who enjoy it please continue. I will take requests of sanscest ships, and turn them into a sin and add some fluff because, fluff is adorable. The story will NOT have rape. All of it will be of consent. Now my sinner family please enjoy!
