Speaking of talking each other up, women do this in just about every social situation including during a three-way. I was once shagging a girl and in the middle of it she and the other girl started talking about their hair or nails or something. I'm just slowly thrusting away and thinking, 'She really should focus". But that's something that women do even if it doesn't seem like the best moment to divert their attention to one another's appearance! I'm used to it now.
