The ex (afterwards) claimed she had gone to have a portrait done for her parents. It _seems_ to have started well enough, but even dressed, it is odd that she was not wearing a bra, and has her blouse buttoned below the breasts. She then put on an open-work, lace vest, even odder for a family portrait! She reported that the photographer at this point noted that he was able to see her nipples. Not that it took much convincing, but he then invited her to take off her clothes. (She reported that from this point he was sporting a large erection in his pants.) I'm sure you can see where this is going, as, yes, he progressed from photographing her at close range to turning me into a cuckold. It is unfortunate that if he did take a shot of his erection sliding into her, I never saw it, but I guess the effect is the same: deep satisfaction for the two of them, the humiliation for me in having some guy take my wife.
