Any tips for giving blowjobs to two guys at the same time?

I have only had this opportunity once. It started off on the sofa very awkward, going back and forth, one, then the other. When we all got naked, they both stood in front of me, facing each other. I held them right up against each other and was able to lick, tease and suck them both easily. One of the best things about doing it with them facing each other is that I was able to tease them by rubbing the head of their cocks together and even taking both in my mouth at once. When it came to orgasm time, it was a combination of stroking, licking, sucking and slurping. When they shot off, they shot onto each others cocks and my fingers. I'm not a big cum person myself, so I was happy to let them shoot on each other. If you are into it, then stroke them both as you suck them both. If they aren't uptight about their cocks touching each other, its a lot easier.
