My how the tables have turned on my old science teacher! I somehow managed to convince him that I'd fuck him if he let me mummify his whole body with cling wrap - what a fool! Doesn't he remember what a terrible disruption I was to his class? Anyone who thinks they can tell me what to do has another think coming ;) I let him sweat it out for a few minutes in my bedroom before I make my way in wearing his favourite little outfit - thigh high socks, sexy short skirt & ALL cleavage. This is what he used to jerk off to when I would tease him mercilessly in class. Straight out of his spank bank and into real life, it's time for me to teach HIM a lesson - a lesson on how to get his balls busted! I cup them in my hands and hover my body over him, slowly pushing my weight into his tender balls, watching his face contort in confusion, pain and pleasure. I squeeze them and kick them, I even press them flat inside my heaviest text book! Each time he endures my beatings I give him a Gold Star - just like he used to do to me. I finally promise him an orgasm for all his hard work "studying" with me and leave him with one final lesson: no one cares about his pleasure. I ruin his orgasm and punch him in the balls a couple times after. I giggle to myself, leaving him bound and helpless until our next lesson. Stay in school everyone! ;)
