Since nobody has mentioned it yet, I've found it works best to try for a DP early in a play session, as sometimes you can have issues with both of the men staying hard if one or both of them has cum already.

My former partner and I tried a few times with the male half of a good playcouple of ours. We never quite got the job done for collapsing in a pile of laughter. But at least we had fun trying!
