He wants to see if there's a limit... The magical size bracelet chapter 31 by SatireMarker

"Going back to bed, little girl," Josh whispered, but the words were incomprehensible to you now so he sent them as a thought instead. "I'm gonna set this thing to keep shrinking you... you'll be fine...and we'll see what happens."

Fuck.

You kept shrinking and shrinking, Josh's body becoming larger than the Earth, then Jupiter, then the Sun. The cock itself was no longer recognisable as such, even the smell of it was gone. You were lost in a tumble of cells...

Josh went back to bed, lying horizontally, but such was the gravitational pull of the massive dick you were now inside that you barely noticed. The cock was shaken about but you just floated about like detritus as you shrank smaller than the red blood cells that had flooded to Josh's engorged cock. What you could see was beyond description, a blur of cells and nucleuses that you were pushed into and out of as they whirled around. You honestly had no clue if you were even inside the cock anymore, but given the extreme heat you assumed that you were.

"Mmmm," he boomed. "Enjoy," he said sleepily, as he allowed you to keep shrinking and shrinking and shrinking as he went back to sleep... your eyesight was fading, so he altered the bracelet to allow you to see everything even as you shrank further. That didn't much matter to you, as you were now in a cock the size of the Solar System. If you kept shrinking, Josh himself would be larger than the known universe. You didn't know how small you would go. You didn't think there'd been any limit on the bracelet's power to shrink (or to grow, as a matter of fact).

You shrank smaller and smaller...protons became visible, which would normally be impossible but Josh's work with the bracelet had been successful. Soon the protons became the size of houses, though, then massive skyscrapers, then planets in and of themselves as the smaller electrons surrounding them became visible. Within minutes - though time also seemed to lose all meaning, so who knew at this point - you were surrounded by an endless galaxy of protons and electrons, then the quarks, which resembled moons, became visible. Your eyes widened with wonders as the fundamental building blocks of the universe were laid bare to you.

But still you shrank. You had no idea what would happen next...
