He bought the voice activated recorder with the intention of using it when he confronted her. He hadn't really thought how his plan could go awry, another casualty of the fog of war. They weren't really at war, but their relationship was not in a good place.
He suspected she was seeing someone. He just didn't know how to bring it up without coming across as some kind of paranoid nut job. He also feared, without evidence, she would gaslight him and convince him it was all in his head and he was merely projecting his own inadequacies and perversions.
What was crazy he thought was how much happier she had become in the past six months. She was still very affectionate towards him, but at the same time very controlling, distant, and even a bit mean. He never knew what to expect because in the blink of an eye she could go from Death Valley hot to glacier cold.
Out of frustration, anger, and hurt feelings, he lashed out and called her a bitch once. She didn't speak to him for days. Not until he literally got down on his knees and begged her to forgive him did she start talking to him again. It took her another two weeks before she was civil and a month before she was affectionate.
She treated him to a hand job and while she was jacking his oiled up penis she asked him if he had learned his lesson. He assured her he had.
"Good, because you wouldn't be getting any more of these if you didn't straighten up."
"Mary, what can I do to make amends?"
She assured him, "John, you're doing fine. Just keep doing what you've been doing since your loss of composure. I wouldn't tolerate a child throwing a temper tantrum and I definitely won't tolerate it from you. You're an adult. Control your emotions."
He remembered tearing up and promising her, "I'll try."
She replied, "That's all I'm asking you to do. We've done enough talking. Kneel between my legs."
He assumed she meant so they could have intercourse.
She stopped wanking him and told him to wank himself.
"Tell me when you're about to climax. Do you fantasize about me?"
"All the time. Mary, you're beautiful and very desirable. Why?"
"Just curious. I feel better about myself since I started exercising every day."
She had gotten him to attend her classes, but he found them too demanding. The women who led the class seemed to take delight in proving how most males weren't nearly as fit as they thought they were.
Mary's body was looking more and more chiseled. She had also gotten very strong. She liked to compete with him. He still had an edge in most things, but time was on her side, not his.
"Close your eyes, John and fantasize, but I don't want to know. Tell me when you're close."
He did as she asked and within a minute or two his climax was fast approaching.
