Have you ever realized that this forum is full of people who ask questions without reading what other guys previously wrote?
this is what most people do: jump in without reading and type.
This is the last sequence of events you have to do in order to trigger the last scene and complete the quest:
1) early afternoon on a weekday: Ann is cleaning Max's room: DON'T ENTER - do something else;
2) next hour: Alice is punishing Ann in Alice's room: DON'T ENTER - do something else;
3) next hour: enter Ann's room while Ann is cleaning her room.
Been there done that 100 times, just like all of us posting and asking about have been for some time.
You say people post without reading, if you had read any, then you would have realized that I've searched and read 20+ pages of results even going back to when this quest was first introduced (like I showed you), not to mention the fact the I have already said multiple times that those chain of events aren't working.
Like I have said in the past numerous times, I (and many other people) have tried that so many times it's unreal.
I have spent several months worth of game time, following Ann around the house. Numerous times I have tried to go into Alice's room but got kicked out. Then I tried others suggestion of not going into the other rooms and waiting for Ann to clean her room then go in (supposedly had to keep doing it until the punishment started) just to trigger the exact same sex scene in Ann's room, which is why I said 100 times (probably around 50-60 if I'm being totally honest).
I didn't just list crap I found people saying, I've already tried them all, which is why I said it.
If you will look right there in my post that you quoted, I've already said I tried those. I guess I should have also stated that I know you can only visit 1 room per day for those events, but I thought that was assumed.
