This man is asking the real questions. Unfortunately I don't have the exact answer
I've had "four hands massage" at other places - its been okay.
The thing is at various semi-legit spas there are girls who do more than others, and sometimes if you're lucky they do a lot more.
So for me the question for me becomes: if I get my favorite girl in on a four hands massage, will she still offer the same services as before? Or will she scale it back and play it safe to make sure she doesn't get caught breaking the house rules in front of another attendant? What if I have two loose girls but they're unaware of each other offering extras?
Anyway in terms of price I'd imagine they might charge you 120/hr for a four hands, plus tip. The reason being theyd rather have two rooms in use with 1 attendant per room - instead of 2 attendants in a single room it's difficult to say and could depend on how many they have on staff that day.
Id love to hear if anyone else has tried four hands at comfort foot spa as well.
