Monsutā ni hentai suru osananajimi - Ch. 14

[kurosawadai1]

I think the last page starts with bottom left when Ayari's screaming hearing her sis and then goes to Bottom-Upper Right where Sagiri/Ayari's Sis' explanation and ends with Shunpei panel. At least from what I'm looking at, it seems that when Ayari screams, her head's facing towards her left and her eyes looking behind her, and then in the sis' panel, she's also looking behind her left.

Keep in mind that this is only an opinion and it might be wrong
