lol, I'm VERY flattered - thanks, Mr. Guest :]
No "rules" regarding couples here - it's allowed and highly encouraged. Price-wise, I THINK the door fee is the same (no double charge), but whatever upgrades you get inside the room is x 2, even if your partner is just watching ... naturally, it's worth the money to join in ;]
I'd love to be part of this duo! I've had a couple session once before and it was quite interesting, to say the least.
