They are great. Because they do 3 ways but only together I am sure it will be no problem for them to just do their thing for you. Also, what I might do and suggest is just way you would like that to happen but for them not to be surprised if you decide to make it a 3-way so you can play with them if you decide to. Figure out any difference in payment and how you will communicate that you want it to be a 3 rather than 2-way with you just watching. They may say that once they start together all you have to do is start taking off your clothes and they will know how things are going to go. Man, I am getting hot and jealous.
