I've been fortunate, and done it a few times, but only with 2 diffirent ladies. A guy will always get "his rocks" off, so it's about ensuring the lady loves it and it's gotta be done by two very considerate guys......and I can say, both of them had a mind shattering orgasm and if done slowly, you can actually feel the other guys head pushing against yours. Also good to use a small vibrator instead of another guy, then the guy also gets to feel that vibrating on his head :)
