"You didn't deny thinking about me while watching porn either, though." Harry smiled and brushed his curls to the side before leaning over the desk so he was closer to Louis. "Do you stroke your big cock to those corny student teacher porn videos? Do you get mad when you watch? Because god, it's so fucking cheesy. But you can't help the way you start to come when the student starts moaning, 'Ugh fuck professor fuck me.' Because somehow it's hot, and maybe it's hot because you want to hear a certain student moaning professor while you fuck them over your desk. Now isn't that right, Professor Tomlinson?"
