Since you appear to have more than enough deepthroats already: how about combining that with something else. I'm a big fan of creative use of clothespins, so I suggest setting up a thread asking people for locations on your body to place clothes pins.
Your goal would be to get up to 10.000 "clothespin-minutes"; so if someone tells you to put 10 clothespins on your thighs for 5 minutes that would be 50 clothespin-minutes.
If that sounds like fun I have a couple of extra ideas to spice that up
