If you're looking for an exp with a porn star take a look at Chloe at HOD (Karlie Simon), at £130 ph, pleasant, unassuming girl,v horny, not as outrageous as her movies obviously but still provides decent VFM IMHO, seen her x 3
British Busty Honey (as porn star Tiffany Kingston) ex HOD, on AW but indy now and bit more £ these days, saw her few times back in her HOD days, quite vocal, dirty talker, toy show etc
The 2 Sugarbabes sites carry a selection of Porn stars, seen Abbi/Louise loads of times back in the day, not a porn star but pretty filthy, enthusiastic provider of all services inc A, can't comment on any others as not seen
Deps what you want obv, I am sure others will come up with alternatives, be lucky!
