This person is right. My reading manga has many hardcore smuts. Here, just look at the yaoi smuts and I guess that would work. There's also http://www.mangago.me/tag/hardcore

I collect the ones that exists here in mangago (though sometimes I link to MRM ). Do mind that my concept is the nasty and dirty for this list so be sure you know what you're signing in for.
