Sonja, middle-aged, that's me, has been married to Tim for many years.

We have a nice life, children living on themselves and studying now and they come here occasionally. We have no "empty nest syndrome" because we both have good jobs and nice hobbies. He likes to photograph also in nature and sometimes takes me with him when he goes to photograph in nature.
We can talk well together about disagreements and differences of opinion. The other day he mentioned that there was a female colleague Jessica at work with whom he got along well. She was much younger than Tim, somewhat in her thirties. He was open and honest about it and no sneaking around. I asked him if he found her attractive. Indeed, he did, so I felt a bit of jealousy and asked on. But he assured me that he will not cross the line and, moreover she is married and has two little children, so was I reassured. He even told that with the knowledge of his photography hobby, she asked him first to make photos of her sewing hobby. She makes women's clothes like dresses and shirts as a hobby. He made an arrangement with her to take pictures and told it to me and I had no objections.
He brought his gear bag with his Canon EOS R5Mk2 and a few lenses with him to her place. Her place it was a nice mansion because her husband Brad was a CEO of a company which does business with companies like NASA and SpaceX. She received him in casual wear, which revealed her nice figure, led him to the large living room and offered him a drink. "Just soda as I have to drive." She gave me a soda and a glass of wine herself. They chatted about colleagues and work and she told him that Brad was on a business trip and her children were to their grandma because of the current school holidays. She also told about her marriage which was not so good now. "He is a workaholic, and he is a good father but gives me no attention at all. I am a mother, but not really a wife, I miss the lover in him" He felt sorry for her. Finally, after two or three glasses of wine, she got a bit flirtatious by touching him which was not needed, but he ignored it and said: "Let's take the photos".
She took another glass and led him to her sewing studio and showed the shirts and dresses which she had spread over the couch on display. He took pictures of it which she liked. "Can you also take pictures of me wearing these dresses?" Jessica asked. "Of course" he said. She left the room and changed and came back in a nice decent long dress which accentuated her curvaceous figure. He took photos in several positions and showed them to her on his phone as the photos are sent over wi-fi from the camera to his phone.
"You are amazing! Sorry for taking your time, but I have another dress to show." She went again out of the room to change and returned in a very short and sexy dress showing cleavage. "You look very good, Brad will like it." Then between the pictures I made, she slowly and gradually opened the cleavage a bit more so he saw her bellybutton and she had no bra. He got it tight in his pants. He thought 'what does she look very sexy but when does she cross the line?'. During taking the next few pictures she gradually revealed her tits in a seductive way and he got aroused. Then she bent forward with her tits hanging downward in a nice way and took more shots. Subsequently she turned around showing her rear which rode up the short pantyless skirt revealing large part of her sexy buttocks and revealing her bare shaven pussy. He got even more horny and said: "It looks like you are doing a striptease for me? You can better do this for Brad."
"No. I need this photos for my profile on an erotic dating site."
"Huh?"
"Yes, as I said earlier, Brad does not want me anymore, I am mother of our kids and a housekeeper for him."
"When a man does not get horny of this, he is either gay or he is in love with another woman. When my wife appears like that, I'll cum spontaneously"
Then she unzipped the dress in her neck and let the dress fall on the floor and she was completely naked.
"What are you doing now?"
"Well I want to show you how you react on it and I see you are horny by the bulge in your pants. I see that you want me, just like I have been wanting you for weeks and now is the opportunity. I am alone so Brad and your wife Sonja will not notice this."
He now had to push the emergency button to prevent cheating on Sonja. Despite being overwhelmed with mixed feelings of arousal and from the other hand not wanting to cheat he took two more shots and he stopped. She put a finger in her mouth and licked on it and played with her tits. His dick was almost bursting, he felt precum and then said: "You are really attractive and sexy and you are right. But I don't want to destroy two marriages. Get dressed please." She was disappointed and took her 'decent' dress on. Then he said "I have to go. I cannot stand this and cannot cheat on Sonja. Whether you cheat on Brad is your business, but I go. I will keep your pictures discreet and will play it fair. Or I can even erase them if you want." "No, keep them, you have a memory of me". He got the memory card from his camera and copied the pictures onto her laptop. It was getting obvious that she is not drunk yet, but still drank too much. When he said goodbye, she grabbed him and said: "Please...." but he said goodbye and left for home leaving her disappointed. When driving he had to be very careful as his emotions had the effect of multiple glasses of drink, despite he did not drink any alcoholic beverages.
Finally he came home two hours after he left. I was a bit worried and asked him: "Was it nice, does she make nice clothing?"
He said nothing and almost got tears in his eyes and I asked: "What is wrong?" He said stuttering : "I almost cheated on you, but I stopped just in time and did not let it happen."
I was a bit shocked and asked "What happened?"
"She let me take photos of dresses she had sewn, no big deal. Then she showed herself in these dresses, the first one being decent, but the second one very sexy where she gradually revealed her breasts and finally took off that dress and stood naked. She said then that she wanted me and I wanted her, but I said "No, I don't want to cheat and do not want to facilitate her cheating destroying her family with young kids. It overwhelmed me so much that I was only able to copy the pictures on her laptop and then pushing the emergency button by going away. I expected a normal photoshoot, not an erotic one intended to trick me supposedly having sex with her."
"Good action of you. It is partly my fault, because I neglected intimacy with you." Then we had a long discussion. Finally he said "we have way too much fun together, familiar, and I find you attractive too and with you I have a life and a history, with her I don't. And no erotic photoshoots from other women, I did not know that she wanted that I made an erotic photoshoot, I was overwhelmed by her actions.".
He continued, "You know, I would like another nice living room sex or making love in the garden or you walking around the house scantily clothed."
