"a crown of thorns" probably, being that it's straight up incest rape/gangbang between father and son and other npcs
"reverse thinking" also pretty damn nasty
"the bad life" straight up revenge and gangbang + almost having sex with a horse
"My x daddy" also incest rape between father and son
"obey me" a classic, but doesn't make it less nasty
also a lot of works in the "gwanggong industrial complex" collection is gross as hell like "keep a dog" etc
"Tosa's master" also freaks me out because it gives bestiality vibes, idk how to explain it
Bad life, nzs, and booty wurk
Is there anything worse than snake hole?
