"Son, it is enough. We are mother and son, we can't do this." Mu Qing whispered softly.
Mu Qing thought that it was enough and decided to stop now. However, Feng Yun's dick was burning in flames right now.
"This is dual cultivation. Who says mother and son can't dual cultivate." Feng Yun said as he gave a light kiss on her neck and caressed her body gently.
"But.."
"Sush!" Feng Yun made a hush sound to stop her from speaking. "Go to sleep, let me take care of everything."
Feng Yun slid his rod into her asscheeks. Her bouncy buttocks sucked in his entire rod. Feng Yun slowly moved his waist back and forth, rubbing his rod against her vagina's entrance.
'Why is so big?'
Mu Qing was shocked after feeling the size of her son's big penis and was shaken up when the idea arose that her son would fuck her with that cock by shoving it inside her.
