Levi rammed his flesh paring blade into Jake's virgin butthole as he let out an exasperated series of oohs and ahs. A thick mist spewed from Jake's rectum, regenerating the torn skin after every thrust. He could feel every muscle in his body tighten up as the pounding continued for another hour, his frail young body enraptured by the corporal's flesh.
"Won't someone see the smoke, Sir?" Jake mumbled between gasps as the two hung from their maneuver gear on the titan-side of Wall Rose.
"No," he responded as he grabbed a fistful of his subordinate's hair and rammed his face up against the stones, "just keep your voice down or the Stationary Guard will hear us."
Levi pushed the blade further in, pushing Jake deeper into exquisite agony as he said, "Corporal, sir...I...I think I'm gonna.." His warning wasn't swift enough as he ejaculated all over humanity's towering cage with a thunderous pressure. He bit down on his thumb to muffle his cries of pleasure and pain and there was a bright yellow flash.
"Dammit," Levi cursed to himself as he zipped up his pants as the explosive transformation pushed him away from the wall, "not again." There were cries from other soldiers on top of the wall as the still-forming mass of muscle and bone fell towards dangerous titan territory. As the muscles took the shape of a ten-meter class Titan, one thing made it stand apart from the rest of the huddling monstrosities; most Titans have no signs of organs whatsoever, however, this one's behind had a large opening and was known only to Levi as: The Gaping Titan.
