First, many, many thanks for uploading this so fast. Secondly, I waited so much time for this and it was worth it! Great job by Fuetakishi and it looks this is going to be another 3 parts with both sisters at the same time. So 9 books in total. With that ending, I assume the next part is going to be the little brother watching her sisters getting fucked and getting even more and more corrupted which leads to the final part with both sisters going full slut mode and the perfect ending for that situation will be with both of them being full pregnant and the end of the story. So yeah, I can't wait for the next part! Thanks again!!!
So the next one is to be the last? Not a bad series overall tho I do miss old school Fuetakishi. There are still some of his older works that have remained untranslated.
