I think you have nailed it, at least my experience was similar to yours. It was a little strange in that our first time I was video taping the scene. I remember standing there filming, while they got undressed, then got on the bed, she went down on him, then he her. Then as this other man lay back watch her straddle him, grab his cock, and guide it in to her (my) pussy. This moment is what I refer to the point of no return moment. I can stop everything and it does not go further or let it play out. I remember the conflict I felt, the surge of jealousy and the difficulty I had controlling my ego. Speaking for myself, I have had no regrets not stopping it. Been married almost 25 years and the wife has had almost 30 men.
