Sans x Reader (Written On A Dare.)

Okay, so my friend decided to dare me into writing a Sans x Reader, knowing that I have never played Undertale or have even watched gameplay. The only things I know about Undertale are the things this friend has shown me, told me, or when she convinced me to read a Sans x Reader so I could possibly do voice acting for her. Seeing as she dared me to do something that I'll probably screw up, I decided to dare her to write a Flappybird x Reader Lemon. Anyways, here a poorly written story....Its a few weeks later from when i started the story and I just played Undertale. It was awesome.
