Two Cocks...one pussy!

There's not much online about this subject. Human anatomy being what it is, there are only a few ways to do it. I haven't done participated in this yet, so anyone care to share their advice, stories, strategies, and pics (if any)? What's it like to be the first one in, only to have someone else crowd the scene? How about the feeling of gatecrashing the party house when another player's already there?

Guys (& girls?),

I'm disappointed. Don't any of you have any stories to share? There are plenty of creampie fantasies out there, so how about generating this thread?
