@TrapCard113 How would this be cheating if she accept it? She even say it herself that he can fuck around as long as she stay the most important for him...
I will never be able to understant your kind of people. If people are ok with polygamy stop going on about how it is bad. Human are made to be polygamous, it's the religion that made them mostly monogamous so stop spaming the comment of all the story with polygamy saying the character should stop.
Let people enjoy their shit!
