"Hmm..."
Bei Ling'er hadn't expected Lu Yang to suddenly change his method of attack.
The moment her passage accommodated Lu Yang's finger, she couldn't help but let out a soft moan.
This moan was very faint, and as soon as Bei Ling'er realized it wasn't right, she quickly reined it in and terminated the sound.
The people around them probably wouldn't notice.
Even if they did notice, they wouldn't think it was any physiological response from Bei Ling'er.
But Lu Yang knew exactly how Bei Ling'er was feeling.
After all, he was very, very familiar with Bei Ling'er's body.
So, he slowly moved his finger.
Not violently, but very gently.
However, the sense of stimulation was still very, very strong.
Bei Ling'er bit her lip hard to keep from making noise while also not allowing any emotion to show on her face.
Even her body couldn't twist...
To tell the truth, Bei Ling'er felt absolutely miserable right now.
