Expensive? yes, it can be. And that is a deterrent since the time really flies when you're engaged in an exciting, sweaty romp. And I usually only get one shot - so to speak - so dropping the hour charge x 2 for this is not an easy choice.
I'm very selective about who I'll double with. Either a regular who has a hot friend, or a existing proven pair who regularly offer such services.
It important to put the fact out there. I met one pair who told me repeatedly they loved it, and loved to play with each other and were hot, and I show up and its "no we never have" and "we don't do things with each other." I walked.
What can be great about doubles is just as you say, Amber. Hands all over, mouths everywhere. A feeling of pleasure so intense you don't actually know who is making you feel that way but you really like it. I like to watch as well as participate. I like to listen as well as direct. I like to command, and to be commanded. I like it when we all try new things.
I one session that really surprised - these two gorgeous women who played together a lot disrobed me and put me in a harness swing thing hanging from the ceiling. they played with me and each other and I nearly passed it out was so intense. Toys came out and in the caring hands of a specialist, I came to learn new things that make me feel really good. Everyone got off it was great.
So I'm saying if the heat is there - doubles is like no other experience - and totally worth it. Be honest about what you do and don't do together, and with/for/to your client. Be reasonable in what you charge and honest about what you like.
Lets do it!
