"What are you two doing?" Chen Mi looked at Yu Dong who was hugging Fang Chi without her clothes and felt speechless. This woman was injured, wasn't she? Why was she even doing something so strenuous when Doctor Gu told her that she needed to stay quiet for months? 

He then turned to look at Fang Chi who had his mouth latched on Yu Dong's pink bud and remarked, "Didn't the doctor tell us that we needed to keep her as relaxed as possible? Is this your way to make her relaxed?" 

Fang Chi's face flushed red in embarrassment, he wanted to say something to Chen Mi but before he could pull away, Yu Dong pressed her breast in his mouth even more, such that her hardened bud would stay where it was. He then heard her say, "Keep sucking. You said that you were going to please me, right? If you pull away, I will be dissatisfied, Ah Chi."
