@ices
actually I'm a little bit confused by the order of these chapters. in some other order, I seen this chapter before the other you linked - that will be chapter 5 here. but both this, and the next chapter seems to take place in the forest, so it's either before or after the visit in the orc village. because after these chapters, there will be some more chapters taking place in the orcs' village.
@Sora_92 Since the Orc kid is with her she's probably using the Orc village as her new base and patiently waiting until they decide to gang-up and rape her.
@HDMI1 Who knows? Maybe XD lol
But, I think proper chronology doesn't matters much at this point. there are a few chapters where it matters, but not as much with this one, I think.
@ices Yes. And like you say, this chapter is missing from Pixiv too. but it is on Twitter. And, yeah, it's pretty likely it would take place after chapter 2. along with the next chapter (which you named "Y").
