Chapter 551: Picking Up Han Bing

Liu Mengyu was stunned and looked up at the young security guard, "You... You're done already?"

Although Liu Mengyu was a bit numb and had seen her share of adult films, she was still young and didn't fully understand those kinds of things between men and women.

She simply couldn't imagine, let alone understand, how a man could finish in just a few seconds.

But what Liu Mengyu didn't know was that her delicate hand had a kind of magic on that young security guard.

Moreover, the words Liu Mengyu said, her slutty expression, and her low moans all stimulated the young security guard.

You could say that the moment he felt the warmth of Liu Mengyu's little hand, the young security guard felt the urge to let go.

But the young security guard didn't want to be looked down upon by Liu Mengyu, so he held on for a few more seconds.

"I... I'm coming... open your mouth!"
