Hearing this answer from his stepsister, Ye Fei was taken aback for a moment, but quickly understood. He had just cum a lot inside his godmother, and since she hadn't started practicing yet, she couldn't absorb it. It would just flow out, making her uncomfortable and creating a strong smell.
If Professor Ming caught a whiff of it, that would be troublesome, so she naturally had to wash up.
"You two talking about something? Ye Fei, come on, let's keep drinking," Professor Ming urged, seeing his daughter and Ye Fei whispering to each other. The brief pause hadn't sobered him up; instead, the alcohol had hit him harder, making him more drunk than before.
"Sure, let's drink. This one's on me, Uncle!" Ye Fei heartily clinked glasses with Professor Ming and downed his drink in one go. Meanwhile, his other hand once again reached for his stepsister's body. This time, he went even further and started to take off Ming Yuexin's pants.
