Dear Professor... I found out about your spanking fetish! I mean, you're constantly staring at your students' butts, and they tell stories about your search history popping up on the projector during class... Something about spanking girls in miniskirts? That's dirty, Professor... but I couldn't stop thinking about it. I know it was wrong of me to steal your favorite ruler, but I couldn't help myself - I wanted to send you video proof that I can handle what you're into. Do you like seeing my big ass in my little red velvet skirt and my lacy black thong? This time, you're allowed to stare - I want you to watch me spank my ass pink for you. Sure, it stings, but I love doing it, especially knowing that your hands have been on this ruler... My juicy butt ripples with every smack, and I moan every time the impact hits. I may flinch, but before long I'm panting with delight as my butt gets pinker and pinker! I spank myself until I'm exhausted and my ass is warm, but it's clear that I could have gone harder... A guiding hand is needed, right, Professor? Please teach me! (Note: Voiceover is present at the beginning and end, but does not overlap with any spanking sounds or vocal noises!
