But her goal was to persuade her sister, so she put that aside.
"Forget how I said it. Just tell me if I'm right."
"Of course you are. You had Yue'er naturally, so his whole body came out of your… there," Su Mengyun said, her own pretty face flushing slightly.
"Exactly. If a son putting his dick in his mother's cunt counts as incest, then I already committed incest once when I gave birth to him. So what does it matter if we do it a few more times—or even countless times?" Su Mengyan said with a smile.
"You… That's sophistry!"
Su Mengyun spat, looking unable to argue back.
"Forget whether it's sophistry or sound reasoning. As long as it makes a case, that's good enough," Su Mengyan said with a smile.
"Aren't you jealous of me?"
"Jealous of what?" Su Mengyun asked, puzzled.
"Jealous that I have a son who can use his dick to show his mother how filial he is," Su Mengyan said with a grin.
