Sierra reminded again: "Didn't you clean up the master last time? Don't remember? Use your mouth!"

Lilu then stuck out her little tongue.

Seeing Lilu busy, Sera's face was full of envy.

Lao Bai said: "If you want to try it, come over."

Sierra immediately climbed over happily.

Lao Bai tapped Lilu's forehead and said, "You are too stupid with your tongue. Let your sister Sera teach you."

Lilu could only reply: "Yes, master."

After a while, Lao Bai pinched Lilu's pretty face and said, "You've done well, you've made great progress. The master has decided to give you a favor. Sit up."

Lilu's pretty face suddenly turned red.

Sera smiled and hugged Lilu's slender waist and said, "Don't be shy in front of the master. Come, let me help you."
