I'm not sure. I usually spread mine out so I can last as long as she can. I can be up again in 5-10 minutes and ready to shoot in 20 minutes if the mood is right. Once during the last session I pulled out of missionary early so I could finish in her mouth. I finished but she kept right on going til I came again in what couldn't have been much more than 10-15 minutes. That fast is rare though; I usually get super sensitive right after and don't want to be touched down there for a few minutes.
