These are brother sister moments featuring all of the members of 5 Seconds of Summer at their current age. The idea is that you have just been found to be their sibling. Most of the preferences will be centered around that idea and hopefully be a slight twist on the standard BSMs. I have personally written all of the content found inside the chapters. Generally speaking, each individual preference is 400-4000+ words depending on how new they are, four to each topic and one topic a chapter. There is at least one BSM for each boy for every topic I write on. 374 unique shorts to read :) Hope you enjoy!!! Highest Rank: #38 in fanfiction
