Let Her Watch From Above
"...B-But Kafi, even if Mommy isn't scared of moving forward in our relationship anymore, isn't it a little rude of you to stick your mother's hand into your pants the moment you see me." She complained about his crass behaviour, which seemed very unlike him since her son acted like a real gentleman most of the time. "Shouldn't you first take me out to dinner or take me out on a romantic date before you can a-ask me to do s-such things?"
"Did Mommy raise you to be such a boorish man who doesn't take the girl's feelings into account and only thinks about his own selfish desires?" She said with a solemn look on her face like she was lecturing her son while her hand continued to work on his dick, perfectly knowing that the gentlemanly way he acted before had nothing to do with her and was something he had picked up on his own.
