She was a wife after all. It was her duty to satisfy her husbands' demands.
Furthermore, she was their only wife!
She had thought about the issue when she was taking a rest in the afternoon. She did not really mind a threesome every once in a while, but the problem was Ye Liu and Ye Mo were practically insatiable wolves and there was this 'competition' going on between them. If it kept going on like that, she would always end up sore all over and have to sleep in the next day.
If they could be half as complacent as Ye Yang and Ye Liu and not be swallowed by greed, she could accept their occasional request more readily.
"Ling, you're so cute when you stutter. How lovely. I was only joking. They won't dare to gang up on me," Liu Duo giggled, feeling relieved.
Of course she would not put him in a difficult spot. If she was unable to stop Ye Liu and Ye Mo from doing so, she would ask Ye Yang for help. She would not leave the ever protective Ye Ling with a difficult choice.
