I was called into the Headmistress's office and told I had to do some extra tutoring at her house. It turns out college courses are harder than I thought, and all that daydreaming about sex during class had me failing. I can't help how insatiable I've been though! Once I finished the work Ms Mountains assigned me, I opened my laptop to watch porn and cum quick. But she caught me, and made sure my punishment stung. I was in real pain. I had marks on my ass for days after! Joke's on her though... it only made me hornier. ;)
