Is elbow deep as far as you can fist?

Two hairy, muscular men grip a thick, smooth cylinder as it stretches one’s asshole wide, his knuckles buried deep, fingers curled around the base while the other guides, sweat glistening on their chests.

His partner leans in, hands braced on his shoulders, holding steady as the fisting pushes harder, the cylinder sliding in slow, deliberate strokes.
