For those of you that followed up to @
matheusilvasilva walkthrough, here's the following :
- continue on doing massage on Monday/Wednesday and visit the couple a few times.
- After a while, when you massage Galya she will mention Katya accept it.
- Visit Katya at 9 am, if she offer you anything, decline (leave option in my english translate version), now advance time to 10-11 am by either switching room or using cheat, stay in hall, you should have a bonding scene with Katya and Galya, repeat next day.
- On the third one, she'll ask you something, no choice anyway. Then it continue at 10 am, if you get the kiss/chat choice, just leave it should pop up the correct Galya/Katya pics (I use cce cheat to go forward/backward in time).
- After the 5th time you caught them in the hall, lesbian scene start properly.
- 6tth time happened on saturday in Katya bedroom's for me, still 10-11am, same for 7th (MC mention a strap-on here if you followed everything)
- Go to the kitchen (not sure if time is important but I was there around 7pm) and you'll have the option to gift the strap-on (can be bought in sex chop in Chkalovsky.
- Next day, back to Katya bedroom at 10-11 am to see them unpack your gift. Next day, same place and time for the conclusion of the strap-on part. You can repeat the scene by going into her bedroom at 10 am. Do that a few times (not sure how many but at least 5 I would say).
- Go on sunday to meet Galya and her boyfriend with Katya at 8pm in business center, make sure it's one of the time where there's only Galya and Katya, boyfriend need to be away (if you dont know how, it rotate between all 4 of you, 3 of you with bf and Galya and 3 of you with both girls, if you use the cheat, just put back time at 20.00 and restart, it works wonder) you'll get the threesome.
And that's the end of content for Katya afaik. All variable have been used as far as I can tell.
