From the description of this comic at the BE Story Club:

Bronwnyn, Alina and Chevvy all long for larger tits. While embarking on a search for a solution to their problems, they encounter a magic fairy who transports them to a land where all their wildest fanstasies come true.

I love the tit fairy premise. And in addition to the main storyline, there's a plot element early on where the flat-chested blonde, Alina, interferes with the boob fairy and winds up being almost instantaneously transformed into a big titty girl.
