Layer Cake is a story written by shukyou and illustrated by Iron Eater. It ran in Issue 61 at http://s2b2.livejournal.com/337059.html, and is mirrored at http://www.shousetsubangbang.com/mirror/layer-cake/.
A baker and a pair of difficult clients resolve their differences amicably, if somewhat messily.
From http://fairyninjas.wordpress.com/2016/06/24/ssbb-61-something-old-something-new/: "Woah. Super hot. A baker of cakes, and an affianced couple looking to order one, except they are both terrible groom-zillas, and have changed their minds just at closing time one night…"
Thanks to Crave Cupcakes for some wonderful flavor inspiration.
