Tawawa on Monday #147: Holstein
Look, it's a nipple coupon!
According to this tweet, Himura is highlighting the fact that he has finally featured uncensored nipples in this comic by exploiting the loophole that they're cow nipples rather than human ones. A "permission coupon", if you will.

I prefer the kun'yomi reading of 牛乳 rather than the on'yomi one.
牛乳 can be read in either of two ways: kun'yomi, the "native" reading, which is ushichichi; and on'yomi, the Chinese-derived reading, which is gyuunyuu.
