Soft-Born Skin: Science Fiction

The sweat beaded along the ridges of her spine, rolling in the clefts beneath the armor plates and making the soft-born skin there itch maddeningly. The first thing most newborn tried to do was itch between their scales when they first went on-mission. The older ones knew that no matter what, they couldn't quite get the angle right, though an abrading shower after the mission would sluice away the sweat before it could dry out to an irritating salt residue. The younglings, though, still itched despite getting lectured again and again. She turned her eyes to the newest. Sure enough, the one at the far corner was surreptitiously rolling back and forth in the dirt, as if she wouldn't notice. As if it would do any good. She hissed.

Inspiration: I was thinking about summer and heat and sweat, I suppose.
