It is impossible now to take her clothes off while in night raid? Or do I have to unlock it?
It's possible, but in all the time I've been playing the game, there haven't been any major updates to the available options...
Oh, how to do it?
Basically, during your adventure you read a comic (hentai) which will increase your desire, it should exceed 30%, after that you go home and select "sleep" and normally you wake up
I never noticed it, I thought it was random or after having nightmares
