"Mmmm..." Yao Ying's voice was muffled because of Yao Ling's hands on his mouth.
Yao Ying grinned and licked her palm slowly with his swirling tongue, which earned him an angry glare from Yao Ling. "Ew!" She let his mouth go and waved around her right palm in disgust. "You are so disgusting!" She whined in annoyance. "Do you know how many germs in your saliva?" As her mother's assistant, this little bit information was a known fact for her. It was so icky!
"It didn't stop you to exchange saliva with me though!" Yao Ying said with a smiling face and he appeared to look as innocent as possible.
"…"
Yao Ling gaped at his shamelessness. "What exchanged saliva?! I never did that with you."
"Tsk… tsk… My innocent wife…" He touched her face and pinched her cheek tenderly, after that he touched her lips and caressed them softly. "We did kiss a lot. Doing that… won't it be considered as exchanging saliva?"
