Alex advanced quickly. "As much as you're liking being so small," he said. "We've got to get out of here. We're not going to find your dad down here without a microscope." Brendan shuddered at the thought of being too small to see, or maybe his body was just quaking from yet another loss of size. He couldn't tell.
Alex scouped his parachute-like shirt off the floor, scraping a cake of dust as he went. Before Brendan could will himself to move, Alex's hands closed around his tiny body once again. Alex folded Brendan into the shirt, face-first into the pink shrink dust. Brendan gagged as he felt his small dick get even harder and smaller, and his fingers and then his arms pulled in towards the core of his reducing body. Brendan flailed against the roughening fabric looking for a way out, but all he accomplished was reducing himself ever more.
Brendan was jostled in the dark about as Alex moved, but suddenly he was free of the makeshift shrinking chamber and in Alex's hand. It seemed a lot bigger now, even though Brendan knew Alex must still be getting littler. "Actually," the diminished giant announced, "I think you'll like riding over here better." Brendan felt himself cupped in one hand, his miniscule erection now pressed against the folds of Alex's enormous nutsack. Relieved to be out of the shirt, Brendan hugged as much of Alex's gigantic penis as he could take in both arms and held on. He looked down at his now-teeny boner, rubbing Alex with each step. If something didn't change soon, he was going to blow.
Alex jumped up the stairs as they continued to get a little bit taller with each bound. He smiled as he felt Brendan clinging and squirming. The trip to the basement seemed to have corrected Brendan's attitude. Alex felt sure the effects of the dust would wear off sooner or later. Emerging into the kitchen, he headed straight for the phone.
