Not in the books, no. I realize that they have to ramp up the sex nonsense in order to attract the (so-called) casual viewers that are oblivious to the existence of the source material but IMO they're taking it a bit too far. Like just because they're on a channel that will give them an R they absolutely have to make it into an R, even in situations where a mere NC-17 will suffice. Stannis never nailed Melissandre, Renly and Loras never blew each other five times a day, there were actually other citizens in Kings Landing besides hookers and johns, but for some reason they're going to show it on TV anyway.
Sigh. Even The Sopranos was more subtle than this.
