It's not got a lot of content yet and unfortunately uses AI art but consider looking into Edgefield for similar vibes
Man have I been waiting for someone to ask me something like this. Degrees of Lewdity is the first that comes to mind, and Course of Temptation has very similar vibes to it, both are character customizations. There's of course the Eva Kiss games: Good Girl Gone Bad and Our Red String, Our Red String is split between both a male and female MC. Klee Prank Adventure if you like the Genshin girls. Ruin Me by Phanes is incredibly kinky in a very filthy and vulgar way. Uni is a great one if you're into degradation/submission. Transylvania is another filthy kinky one with an optional? transformation. Undercover by Slow Burn Games was a solid corruption story with optional? ntr. And lastly, but certainly not least, The Company is easily the best html game I've ever played. I wish I could wipe my brain and experience that one from the beginning again. Enjoy!
