Cock Sucking Academy

I have been set the task of dildo sucking at the cock sucking academy, and i must pass this test to move forward. in order to help my cause, i stick my dildo to a mirror and being to show my skills.  however, it seems i need more to focus my skills so i place a slave collar around my neck and the insert a butt plug.  i try fingering myself and using my vibe, but i fear that is distracting me from my test. to really impress you, my examiner, i use two different mouth training devices to train my mouth to open nice and wide and ensure my tongue is worked very hard!
