The great thing ...
The great thing about Kerry Marie is that she's done so many dildo rides and other, inanimate "sex" type scenes that she's already given us the "PoV" and "here's how it would be like" fantasies. In all honesty she's rode better than many women have a real rod.
So the fact that she's not going to do hardcore does not upset me in the least bit. In fact, I wish more women who do insert dildos and other play would follow the lead of Kerry Marie. If you're going to go beyond just modeling, beyond just nudity, and actually expose your womanly apex and do insertion, make it erotic, make it fun, get off if you can, or fake it if you cannot.
That's enough for me. Work throughout Kerry's career still makes me cum pretty hard, even after seeing the same scenes over and over, like she's a fresh, new tart. And she did not need to take a real cock to do it. Karina Hart has done similar (although she's gone the absolute wrong way in terms of her more recent styling at Pin-up).
