Houtou Musuko to Koi no Ana
Complete | Kyuugou | 2019 released
This story has literally every single trope I HATE - minor*adult, teacher*student, incest but I really loved this story. I would have liked id they waited until Seme was an adult, but it is what is. Also, to those complaining aboit incest- first cousin "incest" was very common in most cultures, as long as you are not same-surname cousins (paternal uncles' kids). It was a way of keeping your bloodline "pure" while also ensuring that u don't end up Hapsburg-looking freaks. Nowadays, it's practiced not in a lot of places, but it's also not "ewwwwww incest"
