'Village Elder! Terrible news! The snow is three meters deep and there's a big landslide on the only road to and from the big city! We're all gonna starve to death!'
Village Elder: *sharpens his knives* 'We'll be fiiiine.'
Big breasts are ugly things that have and brings lots of problems. One of them is the fact that tits are just big lumps of fat; yes, it's mostly fat. As a consequence, the taste is terrible, and the preparation is too troublesome, and this fact is confirmed by some real life cannibals.
So, in the present case, we would not have any pleasure in literally eating this woman's tits (and by the previews in DLsite, the same goes for the whole body), and we would only do this in a extremely desperate fight for survive. And seriously, this is not a good thing: the act eating should be something pleasurable.
