613 Helping his mother R-18

'Its Mother!' Feng Yun said in his mind. Feng Yun didn't know what to do now. 

In the start, he was a little confused, and couldn't understand what was going on. However, he didn't make any sound or movement as he didn't want to embarrass her.

He thought it was alcohol that was making her do this. It would be best if she stopped soon as he can't hold his desire for too long. As her movements were really too tempting after all his mother's figure was top-notch sexy.

Feng Yun didn't want to wake her up and embarrass her, so he continued to lay down, assuming that she will stop soon. A few minutes passed. She still didn't stop.
