OLM-325 A mother’s anus is deeper than the sea itself!

It’s not okay for parents and children to do such things! It’s frustrating… But… I just can’t help it! Mom: “It’s only the anus, right?!” “It’s okay. I’m specialized in anal sex!” To avoid incest, she decides to let her son have anal sex. As long as it’s an anal sex, there’s no need to worry about anything! But between pleasure and ethics… “If it’s an anal sex, then go ahead and do it! It’s just that I’ve had enough of it…” We both know it’s not okay… “Ah, that one is actually a vagina!” “The one a little lower down is actually an anus.” It’s so enjoyable that my mind goes completely blank!
