That would be the domme formerly known as Mistress Mara. Apparently she did the couple show before becoming a mistress for a few years and now she`s gone back to it. You`d think there`d be more customers for a dominatrix than a fetish couple, but what do I know.
I saw her a few times last year- not the best mistress I`ve ever had ( somewhat mechanical and not very talkative) but better than most; she doesn`t rip you off and she is very, very gorgeous; much better looking in person.
I can`t say what she`d be like as part of a couple because I`ve never done, or wanted to do, the voyeur/threesome thing. But to each their own.
