Mary thrust back as Tim began to cum inside her. He grunted loudly and she admonished him, "Shhh, the kids are in the other room!"
"Sorry, your story really got me going," he replied.
"I still don't understand why me talking about having sex with other guys turns you on. I know we have always had an honest relationship and have both been open to others being sexually involved, but wouldn't you prefer to fantasize about fucking another woman?"
Tim sighed, "I've told you this over and over. You are the only woman I really want and the idea of seeing or hearing about you being pleased sexually really turns me on. I know I am not exactly well-endowed, but I know you will always come home to me because we love each other."
"But, it is the same for me. I only want you and I love your dick because it is part of you. I mean obviously we both find others attractive, but part of being your wife is suppressing any urge to sleeping with those guys," Mary proclaimed, becoming exasperated.
"Who says that is part of being a wife? Why should you suppress that drive? I just don't have that drive to compete for any other woman. You know in your mind that society's focus on monogamy is incorrect. I always thought it was hot in college when you had guys falling all over you and I won the honor of being your husband. That was a hell of a sexual spark in our relationship that I wouldn't mind having again," Tim reflected.
"We hadn't gone steady by that time and I was impetuous back..." she stopped suddenly.
Knock! Knock!
"We'll be right out," Mary replied loudly and then turned to her husband, "We have taken too long. The kids' show is probably over. You go deal with them and I will get cleaned up. Thank you for he quickie."
"Why don't you take a bath and relax for a while? I'll take the kids for a walk. Even with the cold, they need to get outside for a bit."
Tim kissed her and went to the restroom before going out to get the kids ready. After he left, Mary went into the bathroom and ran a hot, steamy bath. She was still turned on as she had not cum and was also a little bothered by her husband's words. Were her views about marriage truly a product of society's views of women and their roles in relationships as her husband claimed? Prior to marriage, she had been much freer sexually. After getting married, she had focused only her husband because she wanted children and that desire drove her sexual desire for her husband. Before Aidan was born and to some degree right before Isabel was conceived, she and Tim had sex quite frequently, often multiple times week. While pregnant with Aidan and for about a year after his birth, she had very little desire for sex. They had even gone a month without sex for the first time ever.
Mary had cleaned herself up and climbed in the hot bath and tried to get her mind off the conversation she had with Tim. He had originally been very disturbed by Mary's lack of sex drive for the year after Aidan was born, but he got into reading some weird erotic stories and had even convinced her to let him buy a chastity device, a plastic cage-looking thing that prevents Tim from getting hard and masturbating. Since Mary had not really wanted sex at that time because of the baby, she obliged his desire to role-play with some teasing and orgasm denial. She shook her head and closed her eyes as the heat of the water seeped into her muscles causing her to relax.
Tim pulled Aidan's jacket on him as he shuffled him and Isabel out the door. "She doesn't ever understand!" he thought to himself. After years of trying to explain himself and why he enjoyed the thought of Mary enjoying herself sexually with other men, she still only merely humored him. He took a deep breath and turned his focus to the kids. He talked to Aidan about school and what games they might play that evening. Isabel occasionally interjected with some commentary about her or her brother. Tim laughed and his frustrations left his mind for now.
Mary, on the other hand, did not have an easy time letting go of their earlier conversation. She had begun thinking about her sexual desire for her husband and its wax and wane cycle during her pregnancies. Then she started to think about her children. She loved them immensely and she wanted a third. Even Aidan and Isabel had recently asked for a new brother or sister, which bothered Mary immensely because though she and Tim had spoken frequently of having three children, he had gotten a vasectomy after Isabel was born. She had distracted her kids instead of addressing the issue that they couldn't have another brother or sister because they could still adopt. After the surgery, Tim had explained that he was done and that he preferred to adopt. Mary felt the anger rise in her once again about Tim not considering that she wanted to go through the whole process of having a child again. When she confronted him about it, he shrugged and said she could use a sperm bank. She shuddered in disgust when she thought of the idea. She had to get her thoughts on another subject.
Mary slowly touched herself and tried to think of the quickie, she just had with her husband. She stopped and something dawned on her. That had been the first sex they had in nearly a month and she was not really into it. Why? She realized that she had not been into sex with Tim since he had the vasectomy. Her sex drive had become so focused on having children that now that he could not biologically father another child, he was less desirable, sexually. This explained her being turned on, but still not really wanting sex with Tim, as well as her dreams which usually included various sexy movie stars rather than her husband. She still loved Tim, in fact, her love had continued to grow as their lives progressed.
She looked down to see she was still touching herself. She felt a bit conflicted and as she tried to get her mind off her lack of sexual desire for her husband. Suddenly, a scene from earlier in the week flashed into her mind. She was walking to the car in a parking lot and a black guy whistled and hollered at her from a passing car. She wasn't even attracted to black guys, but she imagined sucking his large dark cock in the back of his car. Within seconds she was cumming so hard she almost passed out in the bath. Could Tim's approach to their sexual relationship be headed in the right direction? Mary thought of the possibilities and started to think that while she might have different reasons for considering what he asked, it might help them both be sexually satisfied. Mary also told herself that it would still be fair because Tim could technically fuck another woman, even if he doesn't go through with it.
After finishing her bath, Mary got herself dressed and noticed that the Tim and the kids were not back. They were likely at the park. She went to her dresser and took an envelope out of the bottom of her underwear drawer. It was the letter that Tim had written her to explain how serious he was about her sleeping with other guys and also to describe the different kinds of cuckolding relationships where the women slept with who she wanted and the guy was monogamous. She had read the letter several times and knew exactly what it said, even though she never had understood his thinking. She was not retrieving it to read again. It also had the measurements of Tim's penis on it. He had always complained that his plastic chastity device did not fit right and had requested a custom one for teasing. The cost had been too high for a custom one for the infrequency of teasing she did to him. She had never been into it because she really had preferred to just fuck Tim. Now she was thinking that it might be time to give him a little of what he asked, since his cock was not as satisfying without the possibility of another child. Before the vasectomy, even using a condom was okay because there was still a possibility that just wasn't there anymore.
Mary turned on the laptop and searched for a custom male chastity device. She read through reviews and chose a steel one and put in the order. Then she went to prepare a dinner for Time and the kids.
Three weeks later, Tim came into the bedroom where Mary was folding clothes and said, "Here is a package addressed to you. Did you order something?"
"Yes, I did. Are the kids busy?" Mary replied.
