Careless Car-Wash (Request)

     Lewis dunked his sponge in the bucket of soapy water and dragged his arm across his forehead to wipe away sweat. It was a hot day to be washing his dad's truck, but at least he had help. "Hey Brian, this side's ready for a rinse!"
     On the other side of the pickup, Brian put down his tire scrubber long enough to grab the end of the hose and toss it to Lewis. It was a coil hose, the kind that looked like a rubber slinky and was supposed to stay tangle-free. Which, Lewis admitted as he caught the hose, it was pretty good at doing. Unfortunately, the endpiece that screwed into a spray nozzle had broken off a year ago. Instead of buying a new hose, they just controlled the flow with a kink and a chip clip. Now Lewis undid the kink, pressed his thumb over the end to create a wide fan of water, and started spraying the soap off the truck.
     Brian finished cleaning the tire and hubcap. "I'm ready for the hose again when you're finished," he called to Lewis. He started moving his stuff to the next wheel as Lewis finished rinsing the driver's side window.
     Lewis was about to toss the hose back to Brian when he had a thought. Kinking the hose, he walked around the front of the truck to come up behind the other boy. "Here you go, Brian," he said, tapping Brian on the shoulder. Brian turned around... and a blast of cold water hit him square between the eyes.
     Brian squawked and rocked backward, spluttering as he held up his hands to block the jet of water. Lewis laughed and darted the spray around to hit him wherever he wasn't blocking. Then it was his turn to squawk as Brian lunged forward and grabbed the hose, yanking it out of Lewis's hands. "Ha!" he said triumphantly, spraying Lewis in the face.
     Lewis darted around the corner of the pickup, Brian right behind. They'd made it halfway around when the hose caught under a tire, and Brian reversed direction. Lewis didn't notice... until he rounded the corner and ran headfirst into Brian's chest. Brian went down in an impromptu tackle with Lewis right on top of him.

     Brian sat up and shook his head, rubbing his chest where Lewis had hit. Beside him, Lewis made a strange noise, and he turned to look -- and saw Lewis staring cross-eyed at the hose sticking out of his mouth.
     Lewis yanked the hose out, sending a stream of water through the air until Brian kinked the hose. Lewis was coughing and spluttering, and Brian started to feel worried. "Hey, are you okay?" he asked.
     Lewis caught his breath, coughed again, and shook his head. "The hose went down my throat!" he said, disbelievingly. "It was all the way in there!" He pressed a hand to his stomach, feeling a slight bulge. "Man, that was weird," he said.
     Brian looked at him curiously. "What do you mean?" he asked. Lewis tossed a sponge at his head. "I mean you started to fill me up like a water balloon!"
     "I didn't! It was an accident," Brian retorted, "and you ran into me! And anyway, drinking a little water won't hurt you."
     Lewis glared at him, then grabbed the hose. "That wasn't drinking, that was -- you know what, I'll show you!" Brian didn't react at first -- his brain was still processing Lewis's words, and he figured Lewis was just going to spray him in the face again -- and Lewis had no trouble pushing the hose in his mouth. The thin tube curved right down his throat, Lewis let go of the kink, and a jet of water squirted down into his stomach.
     Brian tried to pull away, but the truck was behind him and he didn't have room. He tried to push Lewis away, but Lewis had a firm grip, and the hose only went farther down his throat. He was full, so full, and still more water rushed into his stomach... and his eyes widened as he felt his stomach begin to swell.
     He dropped a hand to his waist and found a bulge... a growing bulge. His other hand dropped down to clutch his midsection, and Lewis gasped as he, too, noticed the bump. He pulled the hose out, looking guilty. "I-- I'm sorry, I didn't mean to--"
     Brian wasn't listening. With the hose out, his belly had stopped growing, leaving a smooth round dome that shifted under his hands. "Woah..." he breathed.
     He looked up and saw Lewis staring. "This is... you shouldn't have done that, but this is pretty cool. Really weird, but cool." He stood up and stretched, watching the bump stretch and squash as he bent back, then forward. When he was bent over all the way, his belly button even stuck out. "Wow, that is weird," he breathed.
     Lewis was still staring. "That doesn't hurt?" he asked, his shame already buried by curiosity. Brian rubbed his belly again. "Not really," he said. "In fact, I think... I think I might be able to hold more."
     Lewis's eyes widened. "You what? I... hmmm... how much more?"
