Dark History - Trigger warning

I am placing the backstory of Kian and Key's childhood traumas here, some may not want to read it.  It does involve a lot of abuse.  I left out a lot of detail for this reason, but if you are sensitive this sort of content, do not read any further.  

Kian and Key's parents were really young when they had them, they couldn’t keep jobs, they were leaving the babies with whoever to party and the Dad would beat the Mom etc.  So when they were three, they were sent into the system.  In foster care, their foster parents just wanted the check and the benefits that come with taking in kids, but they kept them locked up, either in the basement, or in a shed, barely fed them, would beat them…it was really bad.  So, eventually those people got in trouble, and they went back into the system.  

Their next family was worse.  This foster dad sexually abused Keylee and Kian found out and to make sure he didn’t say anything the dad made him do things to her too. And that’s kinda how the blackmail kink for Kian started. Kian has never gotten over not being able to save Keylee form this man, nor the guilt of being forced to hurt her too, and to make matters worse, the Dad also forced Kian to do other things…not to be mentioned.  That is why he is more f***ed up than Key’s.  When the teens were 17, finally their parents got them back but it was never the same and that’s why they are so close and only trust and depend on each other.
