Definitely creep.

Jace got out of bed as quietly as possible, and started to grab a wet wipe from a nearby container. "Stop", said Ecaj "Let the nanos do it, they can reuse the resources." As semen seemed to vanish into thin air from him and nearby surfaces, Jace avoided thinking about being surrounded by a swarm of cum-filled nanotech, reminding himself that they'd probably just rebuild it in his balls....yeah that wasn't a helpful line of thinking.

Forcing himself to gloss over the sticky details, he said: "Ecaj, what would it take to refill me for another round, and also increase my cock size by half an inch of length and width?"
"See that cabinet across the room? Eat 3 candy bars from it."

Jace did so, wincing as the left door (the bars were behind the right, of course) squeaked lightly as he looked inside. He paused, worriedly listening for the continued washing and grumbling noises from what must be a bathroom. They continued.

Jace rapidly consumed 3 candy bars, temporarily confusing his brain when the expected energy burst was sucked away into unexpected growth in certain areas. His brain shrugged and went back to conjuring up an image of Lily, her hair a perfectly wavy orange-red mass, spread eagled face down on the giant bed, Jace's 24 inches of cock splitting her ass open as he drove his hips into the bed, his balls slapping her ass and legs so hard they were leaving light marks.

Needless to say, he was erect. Though only 9.5ish inches long so far. His balls were filled and ready, as if he hadn't cum just 23 minutes earlier, and they throbbed in anticipation as he headed for the bathroom door

Trying to be stealthy, Jace slowly pushed the door open, only to find Lily glaring at him in the mirror when he peered around the edge of it.

"And just what are you doing out of bed, #24793?"
