The obscenity ripping out of his mouth as they both vanished in a blinding boil of light and two more Omega codes flashed onto his screen.

They were blind boils, hard and shiny as ripe black grapes beneath the skin, covering her lower belly and disappearing into the wiry mop of pubic hair.

A build-up of frustration that was unable to come to a head and burst like a blind boil, agony that it was impossible to alleviate, a child in a tantrum determined to spite itself.
