Practicing for the day
I use food to practice my technique. Stuff like cucumbers, corn, squash, zucchini, eggplants, and so on. I shove them into my mouth and simulate sucking a fat one. I can fit quite a lot into my mouth, and I find that I'm much better at controlling my gag reflex now. I'm quite proud of my head for having such fortitude - I hope to use it the way god intended one day.
