"Hello, Chad," said Rudy.
"Hey, Rudy, what you doing here?"
"Science Project," Rudy answered.
"I don't have any science project?" Chad said.
Rudy checked his watch, and said, "No, I do. Rick's my partner, and you're our subject, and we should be getting you out of those clothes before you pop."
"Wha- URP!" Chad burped, and then broke wind loudly. He noticed his clothing seemed taut against his skin. "Urp, urp, urp, whad'dya d-urp-do to m-URP!"
"Relax big boy, you're just blimping out. Now let's get that shirt off you first, and then those shorts. Don't try to speak, your orifices should all be sealing up as you inflate. You're already rubberized, I'm surprised you didn't notice.
"MMmurpfh!" Chad said unable to open his lips. He allowed Rudy to pull his shirt and shorts off. He didn't want to, but his arms and legs were sticking out stiffly like they were balloons and he couldn't move. He certainly didn't want to pop. He must already be pretty light, because Rudy was holding him an inch off the ground by his swelling cock. He tied a string around the base of Chad's cock, and started to phone someone on his cell.
"Hey, Rick! Yeah, I'm over at balloon boy's. Yes, and no. He's inflating, but he's still mostly human shaped. We may need to reshape him. Anyway, he's no trouble at present, just a balloon on a string really. When will you be here? That long? Well, I'll take him to his room, and lock the door. I'm sure his family would freak if they saw him like this."
"Mmpgtz!" Chad tried to speak again.
"Chad's sure freakin', but he's not able to do anything about it. So call me when you get here, and I'll come down to let you in," Rudy said walking upstairs to Chad's room with Chad bouncing up and down between the ceiling and carpet at the end of Rudy's string.
