As soon as Alex finished typing the changes and hit submit, Tony jumped to his feet. For a moment the boy thought he was free, but he quickly realized he wasn't in control of these movements. This was just the Chronivac moving him into position for the next change.
Alex followed after the glass boy, once again grateful for the view of his brother's fantastic bubble butt, "Sorry little bro, but I can't risk you doing something stupid like telling anyone, better that I keep you where I can keep an eye on you." He force marched Tony into their shared bathroom, which had expanded to leave a much larger space between the toilet and the sink.
Alex helped Tony down onto his knees in his new workspace, "Here we go little man. Have you figured out what you're going to be yet?"
Tony knelt down in the empty space, back arched and feet splayed in the back so his ass was on display for anyone behind him. He leaned forward and the look on his face was one of desperate begging. His hands came up to cup in front of his face, forming a small bowl that would direct any liquid back and into his open glass lips.
Alex stood dominantly in front of the boy, his soft cock already hanging out of his boxers. He lifted the length gingerly, wondering if Tony enjoyed the show, "That's right Tony, you're my toilet hoe now. I changed it so no one would notice that you're gone, everyone knows that I've got a little brother still but no one will wonder too much where you've gone or care that you're a urinal if they find you." It was the best of both worlds for Alex. He got to use and abuse his sexy little bro and even if he got caught no one would care. With a sigh he let loose a stream of acrid piss over Tony's face. Some of it splashed off into his hands, but either way it dripped down into Tony's mouth, where he'd have to taste every drop. Alex kept pissing, watching the yellow stain crawl down Tony's throat and pool in his stomach. He was filling cute little Tony to the brim. One drop at a time it filtered out of his stomach and into his already painfully full bladder, though Tony's piss was perfectly clear like the rest of him until he had Alex's mixing with it.
Tony wanted to cry out as the feeling of desperation only got worse, he wanted to piss so badly but instead he was a piss receptacle.
Alex's flow tapered off and he smacked the fat tip against Tony's glass fingertips, "I'm not a total monster, my piss will be absorbed soon enough and you'll be back to your normal level of torture. And I gave you your dick back." Indeed, sticking out not far from the slowly filling bladder was Tony's tiny glass erection, though it was solid glass and useless for either of the purposes Tony so desperately wanted it for.
Alex gripped his own cock, stroking it in front of Tony's face, "We're going to have so much fun together." It only took a few moments for Alex to cum, though it would take a few minutes for the thick cum to slide down from his face and into his mouth and even then some of it would simply dry in place like sticky white tears to complete his humiliation.
