Middle story is Ayato x Haruka x Megumi, then Ayato x Megumi. I can't ID the female in the first and last stories? Someone tagged hiroko asahina but neither of the females in the first or last stories looks like her?
p44 - Kim Hotal, her name's on the page 金 湖月 Not sure about 1st story, the milf looks like Ayato's mother Maya Kamina. The story is just "untitled" in the table of contents.
The first character from 1st story is Reika Mishima, the title of this chapter is her surname 美嶋=Mishima. And the second character (pag.9-15), yeah, is Maya Kamina.
