Sans x reader lemon

If u never heard of a yandere. Go to yandere simulator! ITS ONE OF THE BEST GAMES EVER! (Its one of my fandom's if u couldn't tell) Anyway Sans becomes a yandere for you. What will he do? What will happen? What will I write you to do? (Lol)

{THERE IS LEMON BUT READING IT IS OPTIONAL AND WONT AFFECT THE STORY} You've aspired to be a Monster specialist ever since the monsters had left the Underground. You leave on your first expedition to find as much information on each Monster as you could but then you're sidetracked when you wander into a cave, where the barrier once stood, though you didn't know it and helplessly wander into the Underground and meet a strange skeleton who really sparks your interest.

Oneshots Compilation of Sans and his AU!Sans bretheren. (Lemon Warning) Ah yes, Undertale. The game that ruined my Christmas break in the best way. (2015)
