Based on an OTP Prompt I pulled from Tumblr- enjoy!
Honestly there was something cardinal and fulfilling helping your dear Sombra stick it to people who you felt deserved a good wake up call. People who could easily take advantage of you before you could take advantage of them, it was almost like this sick and twisted game you go to play at the expense of these jerks who couldn't wait to abuse you- and you get to punish them for never actually seeing you as a threat. There was only one person you wanted to view you as who you really are, and that is the same woman who gave you the opportunity to do this kind of thing in the first place. Truthfully, you and her had some hot trist’s every now and again, but she was so secretive it almost felt like she could be using you as well. It wouldn’t be a surprise honestly, she could have anyone she wanted as a partner sexual or otherwise- you weren’t special enough to make a big mark on her world… At least, that is what you thought.
