Glamour, Lisa's Special Day.
I think you talk about a different game here, not this one. To my knowledge, BIBOAS doesn't have that scene. I did see it once, but it was a long time ago. Could be one of the fan mods for the original. Then again the dev put in every stupid idea his fans had, it might have been the base game as well. While it opens up a chance for more blackmailing (yay, more blackmailing), it would be inconsistent with so many aspects of the game, would be way beyond credibility - and yes, I consider getting drunk from one liquoir candy being more believable.
No I haven't played any other of the Big Brother games, tried Glamour but hated that it wasn't RenPy. Maybe it was removed but I definitely saw that scene on this game.
I don't find getting drunk from one liquor candy believable at all, while the other stuff is actually pretty believable, if Alice really hated Max so much and didn't want anything to do with him, she wouldn't be half naked most of the time and teasing him all the time, she obviously wants it but would never admit it, she ends going for anything he wants without much of a pushback at all.
For example there's no way in hell a girl would let a guy she hates spank her just because he found she's smoking and is going to tell her mother. Not to mention all the other shit she lets him get away with.
The one character I find really unbelievable is Ann, there's no fucking reason for her to let him away with all the stuff he does.
