This one gets fairly buggy. I think the requirements are too strict. Make sure not to touch any of your other daughters (be sure they aren't corrupted either). Make sure you meet the marriage requirements for at least one other girl. Make sure 'your daughter' isn't the Mail Order (Izolda). I think you also need to not have a wife. You need 30 pregs without 'your daughter' so you actually need 31 pregs. Also 32 pregs gives you a different ending (Utopia I think). You can't have any rapes. You need to have positive alignment. This is best done by having the Fence store your Wapal Indulgence or selling it back to him if I remember correctly the Indulgence messes with the end for some reason). You also need the diamond ring and at least 2 daughters. Single father is likely not the best start for this because you miss out on a bunch of pregs. Also, if you get the Pain Amulet and the Melotine Patch, you won't get any rapes at the beginning of your play through. It opens more starts to use for this. If you use the Internet girls, save before going because you have no control over it being a rape or not. You also need to have less than 5 (or it could be 7) hypnos, otherwise you get the Hypnotist end (#7). If you scroll up a few posts, I put a 100% save so you can get the end without that tedious grind. If you want to see the daughter marriage end, change your first name to "Ender", click "Ending #2", then click on "your daughter".
