Ye Zhemao and Zheng Jun are a pair of Alpha partners. Due to the worsening symptoms of Ye Zhemao’s sensitive period, Zheng Jun finds Luo Sheng, an omega who is extremely compatible with both of them, to comfort him. Luo Sheng doesn’t want to intrude into their relationship, knowing how good they are together, until she realizes their “kindness” towards her. In their threesome life, Luo Sheng can never escape from being pleasured by both of them, and she even has to provide lubrication when they come together. After taking care of one sensitive period, Luo Sheng has to welcome another one. She thought she was just a tool to help them through their sensitive periods until their subtle emotions make her develop a different kind of feeling. If high compatibility is a coincidence and sensitive periods are torment, then the arrival of pleasurable love will bring an endless peak of s*xual excitement.
