I've first seen it on 8muses years ago, but I can't find it now. The main premise was that 2 girls went on a farm to one the girl's relative. Girls noticed that the wife of the relative had massive breasts and she then offered them to eat some homemade cheese and drink fresh milk. Next morning the girls noticed that their breasts grew larger and confronted the relative about it who said that their diary products have this effect on women. There were also other girls on the farm that produced a lot of milk and were milked by the main two girls. The longer they worked on the farm the bigger their breasts became. I think that later they went to a festival where they competed against a former worker of a relative in a milking competition
