That got dark at the end...

But more or less true if you believe the stereotypes about Japanese high grade beef.

I think it's not the cow girl but just those "fat" meats got sliced? Because it grew up in the size by the mysterious drink and massages. Probably magically transformed into a male offscreen just because... Knowing him.

The "mysterious" drink says "SAPPO", and probably means to be Sapporo, a common Japanese beer. So, assuming it's properly labeled, it's not a magic boob potion, just a common source of extra calories. It could be part of the regimen for breast enlargement, as drinking a lot of beer can cause increased body fat. But it's rare that fat builds in only one or two places..
