Hahahahahahahah, let him suck on it until he is old enough, then cum on it while hes watching and he will flip out and then tell him that you were just adding more of what was already there.
i gots a better one, so two girls gave my brother head in the back of his car and he came in there mouths and shit and they needed somthing to spit it in/wash there mouth out, they used a half full mountain dew bottle in the backseat. On the way to practice the next day my buddy that video's is in the back seat drinkin a mountain dew when my brother goes, "did you buy that" and he goes "no i found it under the seat." my brother goes "EWWW DUDE YOUR DRINKIN MY DICK!" the moral of this true story is, always ask before you drink.
