As Jester already mentioned, my woman comes at least once before I do. Usually 2-3 times. This is because orgasm for me really is "the little death" as Shakespeare described it. After I have come, it's certainly game over for me. I fall asleep or go into some kind of wake coma.
If a doggie is present, we go first me warming her up and fucking her to her orgasm. Almost always anally, by her own request. Then doggie is let into the room. He fucks her furiously and she usually comes from that too. It ends with a slowdown of tempo where she sucks the both of us off.
She loves taking it up the butt, but doggie is too intense for that. If it sometimes happens, she's on top of him.
Despite of what you can see in all the porn movies, we are careful to not stick any dicks or fingers that have been in her asshole into her pussy or mouth. Not before washing them off.
Some weeks she only does it with doggie, daily. Some times only with me. Sometimes it's all of us together.
