It could be a form of friendly competition. Maybe they are both competitive by nature and this is a new way to compete with each other. Also, it might be a way to test their physical strength and skills against each other in a light - hearted way. They could also be trying to prove a point, like who is more agile or has better balance.
Jealousy could be one reason. For example, if one wife is jealous of the other's relationship with a mutual friend or in a social circle, it might lead to such a situation.
Once there was a husband and wife who decided to have a friendly wrestling match in their backyard. The husband, thinking he was stronger, underestimated his wife. As they grappled, the wife used her quickness and flexibility to her advantage. In the end, she managed to pin the husband down, and they both laughed about it.
Well, it could be that there is a magical well in their neighborhood. Legend has it that if a married couple drinks from it at the same time, their bodies will swap. Another possibility is that an ancient artifact in their attic got activated somehow. This artifact might have been created by an ancient civilization for some unknown purpose. And if the husband and wife were cleaning the attic and touched it simultaneously, it could lead to the body - swap. Also, a time - traveling mishap could be the cause. If they were in a place where time - travel experiments were taking place and got caught in a time - warp, their bodies might swap as a side - effect.
In a particular husband vs wife wrestling story, the couple was arguing about who was more athletic. So they had a wrestling match in their backyard. The husband was physically stronger, but the wife was more flexible. She managed to wriggle out of his grips and use her flexibility to her advantage. In the end, they both realized that their different physical traits made them evenly matched in their own ways.
I know of a story where the husband and wife were both athletes in their youth. They had a wrestling match to see who still had the better skills. The husband started strong, but the wife's endurance came into play. She kept on going and gradually wore the husband down. Eventually, she emerged victorious. This story shows that even in a relationship, the competitive spirit can be healthy and fun.
Jealousy. The wife is jealous of the mistress for stealing her husband's attention and love. And the mistress might be jealous of the wife's legal position in the man's life.
One possible reason could be stress. If the wife is stressed at work or with other aspects of her life, she may not be in the mood for sex. Another reason might be relationship issues, like unresolved arguments or a growing emotional distance. Also, health problems, either physical or mental, can play a role. For example, hormonal imbalances in women can significantly affect their libido.
Perhaps he has lost interest in the relationship himself and doesn't care anymore.
It could be that they are colleagues working on a project together. Maybe they are in the middle of an important business deal and need to discuss details privately.
One possible reason could be relationship issues. Maybe there are unresolved conflicts or a lack of emotional connection that is affecting their sexual relationship. Another reason might be related to the wife's own sexual needs not being met or understood, so she is unconsciously or consciously withholding sexual satisfaction from her husband. It could also be due to stress or health problems on her part that are reducing her libido or making her less interested in sexual activities that lead to orgasm for her husband.
