Put him into a teasing chastity device

"No," James said, "I don't think you're ready to cum quite yet."

"What?" Cody shouted, "I need to fucking cum right now! Just jerk me off or something!"

"I don't feel like it. It's so hot when you're all worked up and sweaty. I think I want to keep you like this for awhile," James replied. No sooner did he imagine the boy's cock in full rubber encasing than it was done.

James removed the buttplug from the stud's ass and let him up.

"Listen, you fucking pervert! I'm not going to be your sex toy!" Cody began to approach James. Just as he got within reaching distance, he suddenly felt a tickling sensation on his balls that made him stop in his tracks.

"Yes, you are, in fact, going to be my sex toy," James said, "And you're going to stay desperately horny for me as long as I want you to. You're going to let me do whatever I want to you whenever I want to, or else your cock will continue to suffer."

Cody's cock was now engulfed in a tube with small slimy tendrils exploring its entire surface. He couldn't tell if it was a machine or if the thing was alive. His dick strained helplessly in its prison, gushing precum, but he couldn't manage an erection. He fell to his knees, desperately pawing at his engulfed genitals.

James approached Cody and whispered in his ear, "Be back here Saturday morning at nine or it's never coming off. Good luck maintaining your sanity until then." He snapped his fingers and Cody was transported into his bed, still locked in the device.
