From what I know about Dazhuang, he must have stimulated Ruan Xiangyue's most sensitive acupuncture points with his fingers, which is why she had such a strong reaction.
As Dazhuang would say, no woman can withstand such stimulation.
Even a virtuous and chaste woman couldn't bear it.
Seeing her sister moaning so pleasurably, Ruan Xiangyu swallowed hard and said with a trembling voice, "Master Dazhuang, can I... try it too?"
Ruan Xiangyue's face was already flushed, and tiny beads of sweat appeared on the tip of her nose.
Upon hearing this, she hastily said, "Master Dazhuang, please let my sister try too. That feeling just now was really too stimulating, I believe my sister will definitely have a reaction after trying."
Dazhuang smiled, "Alright."
Then, he placed his hand on Ruan Xiangyu's body, slowly moving down from her pale, slender neck.
If it were any other woman, Dazhuang's action would be enough to throw her into turmoil.
