You've been such a brat in my class for weeks and I'm TIRED OF IT. The traditional punishments aren't working, so instead I make you sniff my stinky, sweaty asshole. Get your face deep in there and give it a good whiff. What's that? You're enjoying it? Fine. You can jerk off while you sniff it, but don't you dare take your nose out of my ass. Maybe then I'll punish you by not letting you see my asshole.
