I've seen Marina a number of times and really enjoy my time with her. She's about as tall and roughly the same age as Helen. She's blonde, has slightly lighter skin and is a little less voluptuous than Helen. Provides similar sessions to Helen as well, though as always, YMMV (it took us a while to establish a good relationship). She kind of looks like Carolyn, one of Donald Trump's assistants on The Apprentice. She definitely works Mondays and one other day of the week, I think it's Wednesday.
