The owner (Pixiv Fanbox)

My name is 41353. That's not a real name of course, but good enough for a lactating livestock. I can't remember how long I've been locked up in this stall, as there's little concern for my sanity at this industrial farm. It's rare to see the owner comes down to the barns to check on her money making cows, but there she is. I wonder what am I in her eyes?
