Song Qingchun's heart stopped beating.
So, the thing she had licked out of curiosity with her tongue was a man's lips, the opening she stuck her tongue into was a man's mouth, the two rows of tough-feeling fences were rows of a man's teeth, and the slippery thing was the man's tongue.
Therefore, the series of curious reactions her body was feeling was caused by her passionate kiss with a man!
The man who had dominated her lips had lost himself in the passion of the moment. Now, she could even hear the sound people made during an intimate smooch, an incriminating sound that made the heart tingle and skin blush.
