Episode 2 and 3 are still in the phase of introduction characters and location. The story moves forwards in both. In fact in significant ways. The sex is not the focus of the story, but one aspect of it. Finding out about the bar, getting the first scene with another woman, meeting the Mc’s family, the Mc’s father leaving, several other even more subtle things that occurred, are all building up the story.
Anna isn’t a fully developed cuckquean yet. She has just learned that she might be one and is still figuring out what that means and how it all works. You are getting to see her development into that fetish (which I for one an excited to explore). She didn’t think to ask more questions because she has never done it before. If you remember her rule about calling her before doing anything, well that was because she wasn’t even thinking about hearing about the afterwards. However, we made it so the Mc didn’t call before Cho, but later, and now she has a taste of that aspect. Not just knowing he slept with someone, but that he enjoyed it, and it was good, and he finished inside her… it has peaked that interest in her, so she is fine with him telling her after the event too, so she can ask questions… she learned that, well, she kind of liked that…
Part of her being away is so she can grow as that type of character. This is all something that she and the Mc are exploring. And that exploration takes more than one conversation and suddenly she is acting like she knows everything a typical cuckquean would do. Just something to keep in mind. Th story is on going and many characters are developing and some are even still to be introduced.
