trying to find a yaoi

I read this one yaoi, might've been one shot but definitely shorter than 3 chapters!

The characters were teacher/school staff member and a student. The teacher was the top and student was the bottom. I think it was non-con and coercive too.

They did it in the nurse's office and at the end, the teacher put a tampon inside him. He might've used toys on him too, but I'm not sure.
