BCC 27-30: Low-Res Early Access (Patreon)

I wasn't sure if I should do an internal shot of nipple fucking, partly because I don't really oknow what that should look like. But I basically looked up "milk ducts" on google image search and used a combination of what I could find there and what I'd seen in some hentai comics I was able to find. I might refine this in the future if I draw more nipple fucking, but I think this conveys the idea of how it looks fairly well, right?
