Furry in my class

There’s this furry in my class that seemed fine when I first saw them but when I took a closer up I noticed that they disguised their tail as a butt plug, what do I do? One time while I was taking notes it started leaking and there was liquid all over the back seat and the teacher asked what I was looking at and I just had to say nothing. Motherfuckers please what do I do this is absolutely disgusting and the tail looks so stained.

UPDATE: used safe to say and told my counselor as well as my principal about this and the furry got pulled out of my class which caused a pretty big commotion and apparently they got like a 2 week suspension or something.
