Fantastic discussion. I'm very pleasantly surprised that there are so many woman who enjoy it (I would have figured that they simply tolerated it).
I agree with MrGiz that - all things being equal - a well done set of MMs are better than naturals. But, ultimately it comes down to the provider. If she gets really into it, then it makes it that much better for the guy.
Personally, I'm not a fan of the BJ through the Russian. I'd prefer the lady uses her mouth for dirty talk & moaning. It may be a little theatrical, but ultimately, we're there for the fantasy... So play it up!
