what you are missing is that in order to tell you what you want to know we would have to tell you how to get to it via the walk through, and it would be the same thing and none of us want to go through and tell you exactly how to get one thing. I will say there are TWO threesomes with the sister (might be 3 can't remember) one is on day 3 and the other is on day 6 i believe after dinner. so if you want either one of those we'd have to specifically tell you what to do from point one. there is a cheat here that allows you to go into a room and see each scene you want to see individually so you could look for that or get the walk through.i just dont wanna miss it. And i don't wanna replay the game several times. That's it. If i read walkthrough i will spoil everything, i can't find excactly what i need. I just wanna know where will it be and what behaviour must i choose to get it.
