...Picking the participants is key, particularly if it is to be two straight guys...

One of the keys to the success of that session was that she took charge and directed the action (e.g., "I want both your cocks in my mouth at the same time").
That was followed by three failed attempts at double-pen vaginal/anal. Reasons for the fails: 1) the physical difficulty of everyone getting into the right positions/angles -- looks so much easier in the porn flicks than it is; 2) evident "stage fright" by someone who, ironically, approached me to team up with him (not to slam him -- the twisted spirit may be willing, but the subconscious can be a funny thing); 3) another male participant succumbing to fatigue (we were afraid he was having a heart attack in the boudoir).
Finally, a success.
