Spanking

Harry got hard instantly as he pulled out his wand and pressed it against the naughty schoolgirl.

"For a witch this slutty..." Harry began as Luna moaned. "I think a spanking is in order.", Harry continued, whispering into her ear.

Luna can't form words as she shakes her ass "Well, Professor Potter, I guess I deserve it for being such a slut. I sit in your lessons getting wetter and wetter thinking of you."

Harry growls, pushing her over onto his knee.

"I'll teach you to be a good girl" Harry barks.
