i don't remember details, but you just have to always act dominant. If someone started to fuck you, just roll back and pick other option, lol.
Assuming you don't mind spoilers, with the dom path instead of making Milly passive it makes her aggressive. They go back to Andrea's house and she screws her a couple times. Milly tells Andrea at the end that she owns her now (paraphrasing). I definitely prefer this one over the sub, which was still good but made me a little uncomfortable with how it went down.
