Exactly. I have had the honour of being used like this a few times, when he is deep in my throat and unloads I don’t even get to taste it, just goes straight to my stomach.
Swallowing is not possible or necessary if you have a cock down your throat. Just relax and he'll make a direct deposit to your belly. If he's really deep you won't even taste his load.
Head tilt/chin lift technique is used to naturally open the throat to create an airway during CPR. So it stands to reason that hanging your head back over the edge of a bed, table, countertop, etc. would open the throat and create the perfect cavity for taking cocks. IMO, it's the only position to honestly get a cock deep down your throat and it's not nearly as brutal as it appears. Still, it's best to know the guy who's using your throat because you are truly at his mercy.
