A shock is felt on skin. Is there skin on your tongue?
Like a few other times in my life, a moment ago I "tasted" a 9V battery. It was an odd sensation, almost tingling on my tongue. It did not feel hot but maybe it felt warm. It had a bitter taste. Don't try 126V on your tongue.
A shock can be felt anywhere that there are the appropriate sensory neurons. Indeed, electrical stimulation of nerves well upstream of sensory endpoints can also cause discomfort and pain - they can be felt.
Skin is [usually] considered to be the largest organ and I understand why you might think that a shock can only be felt on your skin - sure that is the most common occurrence. How about if I hook up a voltage source to your eyeball, you think you would feel that? How about in your teeth? There are other places that are not dermal.

It depends on your definition of skin. To avoid the semantic argument, most biologists/anatomy folks talk about epithelial tissue - the outer layer of any organ (and the inner layer for tubular structures). Some are dry and some excrete mucous - depending on the type of epithelial cells on the surface.
PS, "skin" is part of the "integumentary system" which is commonly identified as the heaviest organ in many trivia games.
You should tell the Cleveland Clinic that published an article that states, psoriasis can occur on any skin including that of the mouth and
tongue.
Or the Mayo Clinic that says, skin tags can occur on any area of the skin including the tongue and intestine.
I could go on but I'll let you use your own Googler and creatively search skin and tongue combinations. I understand that you don't like the use of the word "skin" for the surface of the tongue but, that is why I prefaced my answer with, it depends on your definition of skin. Don't shoot the messenger.
Also, one definition of skin in Webster is "the outer surface of a structure".
