Nicotine! Saw her in a couple of Kink on Demand movies.. Acts like a total amateur, which is part of her appeal i think.
Maybe there aren't this many "orgasmic" pornstars out there because in the end, it's just work. The guy's a guy. Rub him the right way, he gets a hard-on (and yeah, I'm just simplifying this for argument's sake). But I'm sure there's so much more to female orgasms that porn bang jobs like what you described can't give.
