Ochiru Seija no Seppun
This is super twisted, has toys and a load of rape. Really uncensored and I own it as a purchase in digital form. Super STEAMY
Sadistic Boy
This is pure smut and SADISTIC PLAY scenes. If you're into Hard-CORE S&M this may float your boat, bought one vol myself for smut factory factor. It's DARK ASF tho
Ousama No Lesson
Own it physical, love the art here and with her Level C books. This was Smutty stuff.
Aishuu no Kanon
This is just hot, even with the seme being a douche
Blood Link
AT ch 66, second season ch1. Time skip over 20 years, so done with the first couple and don't care about the kid's love life... Sadly, I am dropping it here.
Kurohyou to 16-sai
Need everything after vol3
Madness
Shotacon in some parts, warning for that. Since MC is a minor in most of it.... Anyway, this was amazing and I own it physical from Blu. Really violent and has twisted romance, with half the characters literally going 'mad'.
