Give Me Back My Wife

With a beautiful face and a flexible, elastic figure, my wife Sora is a perfect woman. However, why is it that I always lose my erection when I should be burning up in bed with her? I don't show it, but I can feel that Sora is also dissatisfied with our sex life.
I can't keep going on like this forever. I'll make sure to make Sora happy. Even if it means allowing her body to be used by another man...
But something is wrong with this. I only allowed a physical relationship; I never asked her to give her heart as well.
So, please, return my wife to me now.
