A Cold Blue Heart (Sans x Female Reader)

Undertale. You had played it hundreds of times. You had done every single neutral ending and completed the pacifist run more than once, but you hadn't done everything.....genocide. You didn't want to but.....it was like a little voice told you to keep going. Then one night when you where up late playing, everything went black.....
