Dressed in my Onurnees School uniform, I must pass the cock sucking exam if I hope to graduate this term. I am to kneel in front of the F-machine, turn it on and show my sucking technique as the machine thrusts itself into my mouth. With close-up shots, nothing is left to your imagination!

My first test is with a medium sized dildo cock, but for bonus points I must also try the extra large one! Do I pass the test, or should I be made to repeat the term with extra incentives?
