Closing Up Shop (Sheith A/B/O) (Finished!!!)

ABO Sheith Fic That ive been writing in my spare time (so like... 3 am after work) There's a LOT of missed details, but this is part of a huge AU I'm planning so when it's all out together it'll be on AO3 as a series kind of thing. This is a specific chunk that will later be changed a LOT, to reflect the AU. And it will be changed to include Shiro's roboarm :,) which I left out accidentally :,)))
KEITH IS TRANS IN THIS AU AND PIDGE IS NONBINARY. Consider that your warning; if you don't like that please don't read! Also it's Really™ nsfw
