At the end of the sentence, Li Mengying's luscious lips parted slightly, and she gently stuck out her pink tongue.
She enveloped Chen Bin's nipple and began to suck.
"Mmm~ no... stop! Stop it right now!"
Chen Bin, who had never experienced this kind of stimulation, immediately cried out repeatedly in ecstasy.
If it were an ordinary occasion and a beautiful woman treated him like this, he would surely enjoy it greatly.
But now, being tied up with ropes and experiencing this, it was a bit terrifying.
This feeling of being on the brink of heaven and hell made him almost want to collapse.
Li Mengying continued to tease him with her tongue while laughingly looking at Chen Bin.
"Little brother, does it feel good when big sis does this to you?"
"I give in! Please... stop! Ah!"
Seeing Chen Bin's painful expression, Li Mengying released her lips and abruptly moved her head forward.
