Anyway, if i remember his posts right, he wanted to build up to sex and beyond in more than just two days. So it would have been a slow corruption for the daughter and as extra branches he would've added what patrons requested. The extra content at the time involved bestiality with the dog (apparently it was the one most requested, or the first... those crazy patrons..) , corrupting the girlfriend she's currently living with and some fun with a boyfriend (making him watch or sharing her, dunno).
I think there were also plans on eventually bringing the mother along as well, but it's all bits and pieces and his plans may have changed since.
The plans were ambitious at some point, but things change i guess...
