Still got lots of issues.
You really should break away from the current quest situation... It's very much in the "holding your hand because you can't do anything on your own" situation. My suggestion is to set a starting quest and a few milestone quests by utilizing the corruption. I.E. You start immediately witnessing your father at work and your starting quest would be search the internet about gay sex. The second step is to send it to your father BUT it requires a certain amount of corruption, gained by watching porn, jerking off, and all the lovely voyeurism and sex stuff. I would not include every sex thing in the quests (its a bit much) instead have those things just happen if you have enough corruption and completed certain quests. Like you've gotten your father's corruption to 10 (by sending him more gay incest stuff or showering with him) and if you masturbate in the morning or at some other point when he is home then boom, you got your he helps you jerk off scene. After blowing him in the living room then he'll approach you in all sorts of situations. Etc..
This may also help with some of the issues in trying to get things to play, because I spent a week trying to watch dad masturbate and trying to find bro on the web.
