Because she was now completely sitting on top of Lin Tian, having taken him entirely inside her!
This sudden change of events, even Lin Tian hadn't anticipated!
Lin Tian had been considering how to convince his Little Aunt to agree to do 'that' with him, and now, frightened by Huang Yingying's sudden knock, she had sat down on him.
Happiness came too quickly, catching Lin Tian off guard!
"Mom, what's wrong with you?" Huang Yingying asked from outside.
"I... I'm fine, just got a scare from your sudden knocking and hit my head on the bed," Zhou Xinlan said shakily.
"Oh, is that so. I've run out of sanitary pads, do we have any more at home?" Huang Yingying then asked from outside.
Taking a deep breath to finally suppress the surge of stimulation, Zhou Xinlan struggled to say, "It's... It's in the cabinet, go look for it. If you can't find it, just make do with tissues for now, I'll help you look tomorrow."
"Got it."
The sound of Huang Yingying's footsteps faded away.
