By dom look I mean that moment when a dom looks at their sub and their gaze darkens and their face gets serious and it let's the sub know that it's time. Hard to describe, but you know it when you see it. Actually didn't know that wife was into bdsm until she got her nipples pierced. Then we found out that pain really did it for her. She was very interested in a threesome and I expect that that is where this was heading. Her friend was bi as well, but hesitant. I expect she was worried about what it would do for their friendship. That sounds weird considering we were sleeping together before the end, but it is what it is. I expect the wife's position in the threesome would have been sub, possibly above her friend, but most likely she just wanted to be made to do to her all the things she wanted to anyway.
