Classaesium Treakite

Oxygen

Classy breathed, and breathed, and breathed. His biceps grew a couple of inches, his triceps a little less than that, and his shoulder expanded, narrowing down to his waist.
Last night, he had a dream, where four inhumans knocked down the door and asked for him. His mother screamed, and got killed. His father tried to get the shotgun, but got shot. He was left staring at them, until he woke up.
This breathing was necessary. He breathed again, and his height doubled.
He stood up and went to the porch.
With the sun above, he heaved an anticipatory snort.
