You have to dissuade Perry from going to the club, then focus solely on Emma while Alison is there (she'll end up going home with Jeremy if you do).Then pop, up her butt... Its one of the scenes that I basically treat as canon and always go with.
Sorry, I assumed you meant if she sends sexts to Ian... I'm not sure about your question otherwise.
Oh for sure. Hence my comment about Ian not being a saint and being a shitty friend himself.
I generally don't end up having a sex scene with Cindy in my playthroughs, as I almost always end up going with Holly. Although both scenes are incredible and very hot. It does feel like (at least at this moment) that its one or the other. Although Cindy is best girl, I kind of hope Holly will be down for some crazy sex with Ian. You know, the whole church-girl type whose down for butt sex...
