Zack was a low level executive at KRUX Technologies, too low to really know what the business plan was, but important enough to be in charge of a small team of programmers and scientists. He'd get a directive to produce software libraries and a deadline, or given a prototype board and get it documented, and he made sure the projects got done on time.
He'd been successful enough to get his own office and a private executive bathroom. Where he was sitting now, taking a piss.
Something about that just felt wrong. Like even after he was done, there was still something in there. Feeling around, he pointed his droopy dick up at his eye, and flicked the tip with his thumb. Sure enough.. there was something on there. A small woven thread, like you might use to sew with. Figuring it was a scrap from his undershirt or boxer shorts, he tried pulling it off, only to feel it scrape along the entire length of his urethra. Shocked, he dropped it instantly. It'd only moved about an inch, but now it was flopping around. Confused, thinking maybe it was some kind of weird growth or bacterial infection, Zack rolled the tip of his penis around with his finger, and then the thread, fraying the end. Sure enough, it was made of tiny, twisted fibers, and once they were sticking out like a push, he could swear he saw thin points of multi-color lights out the end, like a wire of fiber optics.
"What is this, some kind of probe?" he muttered to himself, and tried gently pulling it out. But after another inch or so, he suddenly felt something else in his dick. It felt like there was something on the thread, like a bead or a knot.
