"Jockstrap?" Chad said as his eyes glazed over. Yeah, that makes sense, he thought staring at Jeff's crotch. That's where he belonged. He opened his mouth, and said, "I - uhm?"
He lunged at Jeff, pulling down the other man's shorts and swallowing his flopping sticky penis. Chad's arms and legs wrapped around Jeff's waist, and thighs.
"A little help here," he said looking desperately at the smirking Chad clone.
His eyes rolled back in his head, as his cock hardened and erupted. The dead weight pulling on his body was gone. He looked down. He was no longer commando. The real Chad was gone, just a jockstrap remained around his waist, hugging his privates. Nervously, he patted his pouch, "That's really Chad. I, mean, Chad is gone, right? Just a piece of cloth now, and you're Chad."
"Well, not just a piece of cloth. The Chronivac retained all of Chad's thoughts, memories, and personality such as it was/ is. See he's your jockstrap, but he is aware. He's got a human mind, just no way to communicate or move on his own. He's sort of like a guy in a coma - who's not really in a coma, just paralyzed, and unable to communicate," explained the fake Chad, as he bent over, and tugged at Jeff's jockstrap pouch, "Ain't that right, Chad. I bet you're totally pissed off now, but there's not a thing you can do about it. And this way, Jeff won't have to change me back, and won't get in trouble with the coach for not wearing a jockstrap. Right, Jeff?"
Jeff laughed and shook his head. "Okay, Chad, if I changed you back into my jockstrap, the real Chad would change back into a human, and make my life a total hell. So it's a no brainer. But remember, Chad, I still own you. So go through Chad's clothes, find his cell phone and tell his folks that you- er, Chad is spending the night at a friend's. My folks won't be keen on you living with me, and I doubt Chad's parents will be either. We'll work something out for next year, so we can be roommates at college, which will make it easier for you to serve me Slave Chad."
"Yes, Master Jeff," said the new Chad eagerly, "But before I do that can I give you a blow job through your jockstrap pouch to help break in the former Chad Walker?"
Jeff rolled his eyes. "Dude, I'm practically dry," he sighed, and gave in, "Okay, go ahead, Chad Slave."
SLURP.
