"NO! YOU CANT JUST MAKE A SMUT BOOK BECAUSE OF YOUR FRIEND! IT'LL MAKE YOU UNCOMFRTABLE!" "Haha, making smut book is fun." I made this Tanzen smut book for mah friend @ariellachan_desu ^^ There is no such thing as bottom Tanjirou here, not in this household, sorry for that but I only stan bottom Zen. So sorry, feel free to request any cause I usually have no ideas, like at all. BUT REMEMBER ONLY BOTTOM ZEN, sorry again- And I make chapters once a day, at least I try lol. ♡DISCLAIMER! I DO NOT OWN THE COVER AND MAYBE, POSSIBLY, DEFINETLY DO NOT OWN ANY OF THE ART THAT WILL BE USED IN FUTURE CHAPTERS ^V^♡
