start out playing with your own spouses and then switch, or one wife join the other couple

We are new . There is a local club that we have been to once and really enjoyed it. They have play rooms and my wife and myself and another couple who are our friends want to try the rooms out. We are all good with sex with our own spouses . The girls are Not sure about the full swap part. They think they would we ok with oral only swap but not girl on girl . Need suggestions as to how to get started when we get in the room. Oh btw the girls are not into girl on girl at all and we guys are not into any Bi stuff. HELP us make this a great first time..
