Shangguan Bing Xue's little tongue was like an innocent little child playing hide and seek as it was at first hidden deep inside her mouth. However, when she opened her eyes and was surprised by what she saw, her slippery little tongue began to move of its own accord as if it wanted to change the game to a fighting one.
On the other hand, Bai Zemin was so dumbfounded that like Shangguan Bing Xue he had no idea what he was doing or what was happening. However, it was impossible for him to deny the fact that the velvety softness of Shangguan Bing Xue's seductive pink lips was extremely pleasurable to feel.
The two tongues engaged for a brief moment as the softness of each other's lips was transmitted to each other's brains and for a couple of seconds, they stayed in the same position as if they were thinking that, maybe, if they didn't move, the other person wouldn't notice them or something similar.
