A few days later Bruce was enjoying a brief respite between seeing patients at his High Street dental surgery when his mobile phone rang, the screen indicating a number that he didn't recognize. "Bruce Morgan," he said, answering it.
"Bruce, it's Karen Claiborne," a familiar voice said, pausing for a moment to let that sink in before continuing. "I wanted to ring up to see how Yvonne is, how you and Yvonne are both doing really, after the other night?"
Bruce reassured her that they were both doing all right, not really knowing what else one was supposed to say in these situations, although he found Karen quite easy to talk to despite the odd nature of their conversation. They exchanged pleasantries for a few moments, and Karen provided him with her email address in addition to her various phone numbers, inviting him to contact her if he should ever have any concerns about things that she and Yvonne were engaged in or about how they affected Yvonne's relationship with him. She finished by explaining that she'd like to see Yvonne again, and asking whether that would be all right.
"Let me get this straight," he said. "You're asking my permission to ask my wife out on another date?"
She laughed a little. "I know how odd that must sound to you," she said.
"I really do appreciate how respectful you're being of me, and of my marriage," he continued. "It makes all of this much easier to deal with, and increases my confidence that we really are making the right choice for Yvonne, and for us. I'll mention it to Yvonne, but if she wants to see you again it's all right with me. Why don't you ring the house this evening, and you can ask her out yourself?"
That evening Bruce mentioned the phone call to Yvonne, who became as excited as a schoolgirl as a result. When Karen rang, later on that evening, Yvonne took the phone into the other room, as the two women chatted away for over an hour. A couple of days later Yvonne went out with Karen again, leaving Bruce's dinner in the oven to keep warm for him since she was already on the train into London by the time he arrived home from work. Bruce found sleeping alone not nearly as difficult the second time around, having greater confidence that his marriage wasn't about to end as a result of his wife's activities. As it was a weekday, Yvonne wasn't yet home by the time he left for work the next morning, but she was there when he got home that evening, and the two of them once again had wonderful reunion sex followed by a nice meal, all accompanied by Yvonne's retelling of her activities with Karen.
Over the next several months they all fell into a routine, where Yvonne would spend 2 nights during the week with Karen, and also one weekend a month, leaving on Friday afternoon and returning home on Sunday in time for dinner. Karen continued teaching Yvonne about various aspects of their kink, and Yvonne became much better at habitually following Karen's instructions. As the two of them continued exploring Yvonne's boundaries and defining the limits within which she was comfortable, Yvonne became more confident in her role as a submissive. Bruce was the one who first noticed this change in her, pointing out to her that she seemed more self-assured and less timid than she had been previously. When Yvonne wasn't with Karen, she and Bruce continued to live as an ordinary married couple would. They also continued their habit of having reunion sex whenever Yvonne returned to him from Karen, and although Bruce was no closer than he'd ever been to understanding why his wife desired what she did, if pressed he would have had to admit that both the quality and quantity of the sex they were enjoying and the communication between the two of them were all better as a result of their decision to half-open their marriage.

A few months later Bruce received another call on his mobile, recognizing Karen's number before he even answered it. After greetings and pleasantries were exchanged, she got to the point.
"I don't know how much Yvonne shares with you about some of the things I have her read, but do you know what collaring is?"
