If worse comes to worst, you can always just try using the debugger or do some save file editing.

I spose if the debugger doesn't do it, then here, save file editing. Find the location your save is in. You can find that easily through the "saves folder" button in the load game menu. Open up the save game in question with a text editor such as notepad or vim (don't use like, msword or w/e for this). Search the name of the NPC you're looking for, should be on a line like:
<code>"npcName": "slavegoeshere",</code>
If the npc has kids, their name will appear multiple times in the save file as "rememberedmothername", look for the other one.
Scroll up from there past the menstruation, interests and inventory blocks until you see the fetishMap block. Under that, one of the fetishes should be labelled as "BeingBred". It has to be a number between 1 and -1. I'm not sure how many digits the float value can understand, so I'd suggest just sticking to like, multiples of .125 or just going all the way to 1.
Needless to say, this is for the windows version. I imagine the linux version is basically the same process.
