Thank you for another interesting chapter!
The story progress is most interesting!
Nice that the girls are learning to share the mc too. :-D
Anyway the only complaint I have is that you did not provide an 'End of Chapter. Save here!' screen for us to know when to make an end of content save.
I had to reload from the 'pet yuki' choice, then fast forward a bunch to make a save for that. :-o
Please provide one in future!
