This is an agricultural school where "milking cowgirls" are raised.

Their appearance may be that of a human woman, but these girls are nothing more than livestock.

By having sex, their hormones are activated and they can produce milk.

The one who enters this agricultural school is Shinichi Suzuyama.

Unaware of the school's circumstances, Shinichi enters the cow barn to find bare naked cowgirls getting down and dirty with their keepers.

The cowgirls selectively bred to enter heat easily are especially fond of big dicks.

Seeing Shinichi's enormous package, the cowgirls can't help but...

If you love lactating cowgirls and harem sex, this is the story for you!
