This is an inevitable topic considering Mattie's cow form. It won't be frequent, but I'll probably have to utilize lactation now and then (in Ego Trigger, cowgirl milk is a rare and super nutritious drink).
As this comic shows, at most I'll portray it indirectly, usually by having her facing away or out of view. I'm not sure if I'm pushing it though by having the milk drops visible: I originally had a small trickle of milk dripping off her breast at the end, but felt that might've been a little much.
I also wasn't sure if I should've shown nipples. I get the feeling that visible lactation from the nipples might be pushing it too far here on dA, and even showing them before the lactation might set the mood to be too sexual.
Bottom line: as usual, I want to keep things cute and humorous instead of blatantly erotic. Pervy, but not pornographic.
