Try not too have too many pre-conceived ideas about what you'll do or expect. Some things are OK, and let the ladies know. I guess my point, is to be open to the experience and to not lock it in to something before you ever get there (generally good advice anyway).

If the duo is experienced (say Sonya & Ashley) they can probably help out some. Just don't lie there like a bump. You will likely find each lady is very different in what she likes and allows (fingers - yes/no for example).

For me, I knew I wanted at least two things, and one was a given (the visual double BJ). #2 was to have both available for DATY at the same time.

Ah, have fun while trying to make something work...

and let the action take place; don't try to force any activity.  If the ladies are into each other, your date will be even better.  Hopefully, you have more than an hour booked.
