Karuna/Katy is exactly as her pics in the flesh, a very attractive and very fit lady
She's also a proper masseuse, so if you do have aches and pains she can sort them out. B2B was well done on the times I've been, but ive not experienced or seen any reports (on the more fbsm focused forum) of RO.
Also she can come over as a little distant, and going through the motions. There is another lady there, Victoria, she comes over as more friendly and open, but her session is much more on the soft and sensual side so dont expect a massively threaputic session. Only seen her once, and again no RO on the menu
