Alexstrasza runs out of sweets again and since neither Chromy nor Nalice has any more left either, because she has eaten their whole stashes already too, she decides to head over to Dalaran to visit her all time favorite candy vendor and by now best friend Aimee.
After she is done with shopping and stuffing her belly with all kinds of sweets by tasting everything Aimee currently has to offer, Aimee tells her about her top secret brand new cream filling. It's made for her pies and doughnuts, but she could have a little bit, just to taste how delicious the new things will be.
Tasting that little bit of Aimee's new cream filling ends with Alexstrasza gorging herself on the delicious, thick and creamy liquid and her whole body, but especially her belly, growing bigger and bigger. Aimee is very happy that Alexstrasza loves her latest creation so much and gladly gives her everything she has, excitedly watching her round body expand and wondering how much more she can drink and how much bigger she can get.
