Mei the Cow Girl is a Holstein breed, but her body is completely that of a human woman. Moreover, she has a happy erotic face, and her breasts are large and soft-looking. She's a chubby cow girl who makes my dick stand up unbearably. Therefore, "I," her owner, am secretly keeping this cow girl Mei-chan in the basement of my house. You might wonder why, but it's for so-called breast development. I was persuaded by BOTAN to definitely make a video of a part of this basement breeding diary, and that's how this work was created. Because it's for breast development, I'm raising her every day so that she can produce milk... but even though I say that, it's not Mei-chan the cow who produces the milk, but somehow it's always me, the owner. This is Mei-chan's fault! Because Mei-chan, despite being a cow girl, repeats estrus every day, only asks me for things, and sometimes, when her estrus is too much, she suddenly attacks me! Oh, really, I'm really troubled too! Thanks to her, my milk storage is empty every day! She's a troublesome cow girl, Mei-chan! Everyone, please see Mei-chan's troublesome side in this work! You'll definitely be left high and dry!!
