Hello, it's nice to have you comment here, my friend. Well, the "hardcore" part refers to some specific content. It's good that you asked first. A while ago, I created a full set focusing only on blowjobs, titjobs, and deepthroat. I have a lot of ideas stemming from that. I don't usually do them because people tend to prefer more traditional sex, but I can, of course, do a set exclusively of blowjobs if you'd like, and explore different positions.
That "hardcore" part involves things like slapping, choking, more aggressive deepthroat, and face slapping. Some people also dislike smegma (I did a set a while ago focusing on that), which is why I include it in the hardcore tier (Tier 2). Some find it too nasty and gross. I offer some choices to allow people to avoid the hardcore tier and such content. Other things in Tier 2 include hair grabbing, aggressive full nelsons, gangbangs, double blowjobs, double deepthroats, forced deepthroat, forced blowjob, humiliation, or the "gals falling for the villain" theme – things like that. Some of my members don't like that heavy stuff; some prefer lighter content, like cuddles, passionate sex, and so on. My Tier 1 is lighter, while my Tier 2 is a "nasty gift," but I don't do weird things like vore, necro, or gore; that's too much.
