My tutor Mr big gave me a bad grade. I had to think of a way to stop him from giving me bad grades. I tied him to a milking table. Mr big had a big load and he was dying for a big release. I decided I would deny him and I wouldn’t let him get his big load out. I teased and denied him with my tongue for 30min. Mr big made a big mess on my chest when I finally allowed him to release
