I read R-rated stories and I so love them.
I get wet over those guys and wish I'm the one doing that "thing" with them. I mean who doesn't? If not, you're a very big liar!
But BDSM is a Big NO-NO for me. Violence ( yes I call it violence) is just a total turn-off. I tried to avoid  reading stories with vague idea of who is paired up with whom because it honestly annoy the hell out of me.
 I welcome invites on reading your own R-rated stories. I can give you an honest-to-hell review.
