FWIW I saw Delta at an LMP party a long (6 months plus) while ago. Service was the usual for an LMP party, but she seemed to prefer having one guy at a time. OWO was OK, nothing special. She didn't strip off at all and was wearing a bra and fairly opaque baby doll, I assume because she'd put on a bit of weight since her porn days (as per azrael's comments that I agree with) and was self conscious about it she wanted to stay covered up. Sex was a little awkward, she was very tight and wasn't keen on doggy, preferring mish. I assume because she could keep to one guy at a time that way and would prefer a going through the motions approach. Parties were clearly not her thing.
That said it was only the once and I haven't seen her 1-2-1 though, that said I don't think I'd bother.
