Every advance by Su Fan pushed Wang Fei to her limit, even expanding the boundaries of what she could endure.
But such limits are impossible to expand indefinitely, just like a person practicing running who may not be able to run far at first.
After running for a while, they can run much further.
At this point, the desire to run faster and further becomes incredibly challenging, because they have reached their limit.
Wang Fei was the same; she had, in fact, been brought by Su Fan to a kind of limit.
Under normal circumstances, she would absolutely not feel the tearing pain, at most being completely filled.
Su Fan's "dragon vein" was akin to the size of Wang Fei's wrist, and it was not only powerful but also a sharp spear that felt as if it could pierce through a person.
More than once, Wang Fei felt as if Su Fan wouldn't stop until he had completely penetrated her.
