I know it's hard to find really hardcore stuff with romance. I love bousou Kareshi. That's the level I'm at but I would love even more hardcore. I'm not a big fan of rape and stockholm syndrome. And I hate incest. 🤢 My favourite is when they use toys and I also enjoy s/m but only if they're in love. I am very much a huge romance fan. Also I only read yaoi. Thanks guys 😀

Yaoi.... What else is there?! 😉

how about KARESHI GLAMOROUS? Ropeman? KANPAI! DJ - UNAPAI?WARU AMAI MITSU?
Minami Haruka - author she write stories like no toy
Chitose Piyoko- author

Now and forever, i been your most loyal servant

Crimson Spell
Sex Therapist not sure if the s/m & the romance happen together, but it's got both in the series

Rikugun Renai Shikan Gakkou If you can get past the first chapter (can't call it anything but rape) I think it't be worth it for what you are looking for.
Hard Core Heart again, worth it if you can get past both father and son going for the same guy (the incest from the tags is one of the additional one-shots, not the main story)
