[Work in Progress] My little sister is way too much of a pervert

Hello, all!!. I am truly sorry I haven't updated the Wise x Belle doujin in a while （＞人＜；) So, i want to give you guys an update, I would like to share with you all the rough sketch of the first half of this doujin. I don't know when it will be finished because I'm also doing my commission, but the rest of the rough sketch will be uploaded as soon as possible, thank you so much! 🙇‍♂️
