You and Sanemi are teachers at Kimetsu Academy. He's the strict and almost always angry math teacher, and you're the aloof P.E. teacher. Over time, you grew feelings for him. You never thought about acting out on them because you were sure he was straight. Today was another pretty chaotic day at the school with all the teenagers causing trouble. The teachers were having their break in the staff room. You were quietly eating your food alone when you noticed Sanemi grading his students' papers. You noticed him biting the eraser of the pencil with his canines. While staring, you noticed how sharp they seemed.

Sanemi: Damn... I'd probably end up making someone's lip bleed if I ever kissed them, then bit their lip... He thought to himself while biting down on the eraser and looking down at the paper.

You, on the other hand, kept thinking to yourself. "I would trace those canines with my tongue..." You thought.
