The slap was strong and forceful, definitely not delivered by Zhou Yuping, but rather by Chen Bin's powerful smack.
From the very beginning, Zhou Yuping intended to let Chen Bin satisfy his cravings on her daughter, which is why she arranged this scenario.
As soon as Cheng Ying stripped down and knelt on the ground, Zhou Yuping lightly tapped Chen Bin's arm, signaling him to give a fierce smack.
Chen Bin lifted the thin blanket and saw, indeed, it was Cheng Ying's round, perky buttocks.
Her forest was dense, vaguely revealing the pulsating scenic spot, but the 5A-rated landscape was closed off, obscuring a clear view.
At this point, Chen Bin wasn't afraid anymore, having witnessed Zhou Yuping's prowess firsthand, which terrified Cheng Ying enough to not dare utter a word of protest.
So he raised his hand high in the air and then brought it down fiercely!
What followed was Cheng Ying's piercingly loud exclamation!
"Ouch!"
