The home stuff got entirely reworked. Westane removed those old interactions with the family years ago, you can't force them anymore. I don't think the corruption stat even effects behavior anymore. It's all about doses now.
Too bad. I sorta liked how it fir the theme of the story. Like Stockholm Syndrome. You raped your family, maybe even knocked them up, but as the story progresses they get more and more affection and corruption. Like they know that a family member did such a heinous thing, but they can't do anything about it. Worse, the longer it goes on the more they like it, any hatred or anger or revulsion they might have had turns into "love," acceptance, and even anticipation. They can't help it, because the MC runs on mind-control drugs and a game-system that forces that on them.
It just feels so appropriate to this game. Exactly what the Comnay is doing, but more refined. More taboo. You start with family, you fuck them up hard, and then your slowly get them to accept it.
The strange strap-on has similarly been relegated to one of Ava's many dosing routes. Can't just put it on her willy-nilly anymore, unfortunately.
Hmmm... good to know that I can still expect it to happen.
I think you might be able to achieve your goals though. Ava on the strap-on path can be kinda switchy. Tasha, too, though I haven't explored everything since her rework.
I think Tasha doesn't let that happen if you try for the girlfriend route? Which is sad because while I do like the idea of romance, I also play the game with the thought of fucking up the other characters' heads.
And I bet that the strap-on path requires that you become the bride. Which is fine with me, but I like to keep my MC as trans, and like both her and her mother as brides. Both of them walking up the altar in wedding dresses.
