"Smack!"
Zhao Chi gently slapped Liu Sitong's perky buttocks.
Though Liu Sitong wasn't hurt, she was startled and turned around, looking at Zhao Chi with sultry, silken eyes, she pouted, "You, why do you like hitting people so much? Are you trying to play some kind of SM game?"
Holy moly!
Zhao Chi was stunned for a moment, realizing that actually women may be even more knowledgeable than men, he hadn't expected this young lady to understand even SM.
Zhao Chi tenderly kissed Liu Sitong's cheek, "Silly wife, SM isn't this gentle, how could I bear to let you be in pain?"
Zhao Chi's voice was very gentle, and his actions were very tender, but in the next second, his expression changed to a serious one and he said, "Student Sitong, who lies down during class time? Get on your knees quickly, teacher is about to start the lesson!"
Liu Sitong felt somewhat amused, but still obediently lay down on the bed, even deliberately sticking her buttocks high in the air.
