Josh keeps shrinking you even further The magical size bracelet chapter 30 by SatireMarker

Josh used mind control to force you out of the glob of precum and then shrank you even more, accelerating the rate. His laughter, his cackle, took on a depth of pitch that made it almost unrecognisable to your microscopic ears as you went from 1/10 of a mm to 1/100th down to a micrometre.

Now the individual cells of the megadick you were inside were visible. "Whoa," Josh said as he saw what you were seeing, the vibration of his voice a physical force even from what was now miles away. The sounds of the throbbing dick had become a roar, pounding at your invincible ears.
