Did it at Halfmoon with Chloe and Scarlett. House price is for one, extras are double as you are naturally paying for each.
Of course the happy ending is double even if one is doing it and the other fondling other parts etc. The math was..90 for 30 minutes with one. If the house price is 40, then for two the cost is 40 plus 50 x 2= 140. Any extras on top of the happy ending is also x 2. Not able to mix the extras...ie ask one for topless and not the other. Both have the same extras, even if one does the HJ. Seems to make sense for the house as they theoretically attract more clients, and keeps the girls busy.
They are nice but its not really for me. Would not repeat. Maybe with Scarlett alone even though limited extras I find her nice to do massage with.
4 hand massage, even in the normal rates, can be fun , especially if both of those doing massage are into each other. That's a whole other review that can be really memorable.
