Hobbyists should note that "spitting" can be used as a masquerade. I'm thinking of one provider in specific, but as I have no proof I won't name her. She claims and most of the reviews say she is a spitter. However, she's probably very adroit with her tongue and lips, and when she takes Jimmy in mouth, she promplty covers him with a nice hat.  You don't notice because the subrafuge usually goes on in the 69 position and you are far from the action.  So she huffs and puffs and even though your sensitivity and pleasure are well lessened, you don't suspect a thing. Bang,, off you go. Then off she goes to the bathroom where she makes a big issue of spitting and caughing out the goo, as if she's got a gallon of milkshake in her throat, when all she's actually done is dumped the envelope in the waste bssket. No, it's not one of the crimes of the century but you have been mislead and aren't getting what you paid for, and what you wanted. So maybe it's better to spend the extra bucks the swallowers generally charge and know you're getting the real thing.
