Here's chapter 2 of wasurena, chapter 1 can be found here: https://e-hentai.org/g/490301/b45d3268eb/ This is (part of) the backstory of when the siblings had their first time.
I'll probably combine all these together once I am done with all the chapters (if that ever happens), might be a while. Also probably could make a credits page.
This looks promissor. Thank you and good luck with the project ;] I liked it. (I already did this commentary on your 1st Chapter, but just now I realized you already finished the 2nd one)
