I don't know about you but if I was making up a story to get a teacher I didn't like fired, I wouldn't say I let him suck my toes. Imagine how much flack one would catch for this. I'd say he hit me or something but not suck on my toes. So, I'm thinking they're telling the truth here.
But maybe they just came up with a story that was so ridiculous no one would think they could just make it up. Who knows these days?
