It's her again, turns out that her AU is entirely in black and white. To show this, here's her and her normal friends doing normal relaxed stuff. Side note but did you know that it's actually possible to lactate without being pregnant? It's called galactorrhea and it causes milk even though the person is not pregnant or breastfeeding.
Also while most people think that female cows produce milk always, they actually need to be inpreganted to do that as well. So if you think you can make a cowhuman hyrbid to justify such fetishes, you shouldn't even bother. Although at the end of the day, I suppose lactation in this context is there to show how big the boobs are. How else are you supposed to show how huge and sensitive her breasts are if they aren't pouring milk out like a fountain?
In the end, I don't think I have a lactation fetish anymore. I just added it because someone would probably like it I suppose.
