That's it slut, fuck your face with the giant dildo. Feel it force your mouth as wide open as it can get as it searches for the back of your throat.
Now, I want you to push that huge dildo as far back down your throat as you can go and then hold it there. As you start to gag, you are to jerk your cock as hard and as fast as your can. In fact, your gag cannot end until you reach an edge. If you stop gagging before you edge, pull the dildo out of your throat and smash it against your cock and your balls ten times as hard as you can.
You can't move past this staged until you've edged with the dildo stuck in the back of your throat as you gag uncontrollably.
Go on slut, choke on that dildo!
