After school is over, Chad and Karl head back to Karl's house, "you really have been a good boy, Chad," Karl says as they enter the house, "time to get out of those things, boy! You have earned a reward".
Chad feels a sudden burst of joy, he quickly strips out of his clothes and plops down onto all fours. he then follows Karl into the living room.
Karl opens his fly and pulls out his musky sweaty cock, he then sits down on the couch and looks at Chad, "come and get it, boy," he says with a grin.
Chad does not waste any time, he hurries over and starts to lick his "Master's" cock, Karl leans back in the couch and closes his eyes, stroking Chad's head, "oh, yes! Keep it up, boy," he says, "good boy, Chad!"
Chad starts to suck his master off, neither one of them notice as thousands of nanobots start to crawl out of Chad's mouth and enter Karl's body through the tip of the male's cock.
Bruno's tablet pings, the teen, who is sitting in his living room watching some TV, picks it up and opens the App, a grin appearing on his face as a file reads: "Subject two Karl ready for use!"
