Natural Flow
Arthur is very happy because Margaret accepted Nyx as her sister so well, but that's not really a surprise since the girl is so loyal and devoted to him. But like anyone else would, she has many questions about his bond with a succubus.
He spends a whole hour telling everything about Nyx to Margaret, and as soon as he finishes, Nyx asks him to leave them alone for a girls' talk. "Alright," He kisses both their lips before leaving the room with that wonderful taste in his mouth.
Nyx can currently keep her body anywhere in the house as long as Arthur is inside it. That distance increased a bit after she swallowed his seeds for the first time and both felt their Astral Energy stronger.
She is a little shy to be in the presence of another person without Arthur, but Nyx still tries to put on a confident and friendly expression when gazing at Margaret, who also becomes shy and a little concerned.
