You need to use the blindfold during sex with the wife first. Then that puts you on the secret path with the step-dad.How do you do get on the secret step-dad route, searching the thread I saw some people mention that some routes are used as placeholders so is it just not in the game yet or something? If it is in the game it seems like I just end up on the sub route if I follow the in-game hints so is there a more specific order of events the hints gloss over that I need to do or something?
