Have them give him a blowjob.

Jason proceeded to take a seat on the nearby chair, and started to undo his pants. "Alright, both of you, start crawling over to me. I'll be having you suck my cock."

As Adam and Christie sunk to their hands and knees, crawling over with a mix of trepidation and excitement, Aza approached as well. "Should I just watch, Master, or can I participate in some way?"

Jason thought about it as Adam reached him first, extending a tentative hand towards his growing erection. "Massage my shoulders," he decided as he sighed with Adam gently grasping his length, while Christie also reached him, and began to caress his testicles.

"Okay~!" Aza grinned, immediately getting behind him, leaning over the back of the chair, and placing her soft, gentle hands on his shoulders, rubbing on them. Adam meanwhile slowly started to lick Jason's shaft, and Christie leaned down, extending her tongue to do the same for his testicles.

Jason sighed and relaxed, letting the three do as he instructed. Adam continued licking, getting less hesitant as he did so, letting himself be swept away by his need to serve Jason sexually, and allowing himself to simply enjoy the experience without worrying about other concerns. He moved up to Jason's tip, circling his tongue around it with a happy moan. Christie meanwhile moved to licking his length as she used her hand to fondle his scrotum.

"That's it..." Jason coaxed. "Adam... Start sucking." Adam nodded, and lowered his mouth as he parted his lips, taking the tip of Jason's cock between them. He moaned in pleasure as he started to lower his head, causing Christie to shift back to licking Jason's balls to give Adam room to take Jason's full length into his mouth. Adam then began bobbing his head, placing a hand on Jason's thigh for stability.

Jason smirked a bit, enjoying Adam and Christie's efforts. They were both clearly turned on by how much control over them he had, and we're setting aside all the other concerns regarding it. "That's it, good slaves, keep pleasuring me..." Jason sighed in contentment. "Make sure to swap regularly..."

Adam, taking the hint, pulled off, letting Christie move up, and engulf his cock in her mouth, taking it slow like Adam had, and Adam moved down to lick Jason's balls, before pausing. "Um... Jason right?" Adam asked. "Or would you prefer me to call you Master?" He started licking the testicles as he awaited an answer.

Jason couldn't help but smile at the question. "Jason for casual conversation, Master for sexual experiences," he decided, giving a moan of pleasure as Adam and Christie kept working on his length.

"Yes, Master," Christie purred, pulling off of his shaft, and switching places with Adam again. As Adam once again moved his head up and down on Jason's cock in a steady, but accelerating rhythm, Christie sucked one of his balls into her mouth.

"Ah, oh yeah, keep it up..." Jason sighed, talking to all three of them, Aza obliging by making the massage a little more intense, using her elbows to work between his shoulder blades.

The enslaved couple once again swapped, Christie taking his whole shaft into her eager mouth as Adam lowered himself to sucking on a ball. At this point, Jason's cock started throbbing, and he grit his teeth. "Both of you, pull off, but stay kneeling, and open your mouths," he grunted. "Adam, use your hand to finish..."

"Yes Master," they both said, pulling back and putting their faces close together and letting their jaws hang open, their tongues extended. Adam began stroking Jason frantically, as Christie used a hand to caress his scrotum, not even under orders, but out of desire.

Jason grunted, and his member released the floodgates, several jets of seed erupting forth. A couple spurts hit Adam and Christie's tongues, but the majority painted their faces. "Ahhh..." they both panted, letting their hands drop as they gazed up as Jason, awaiting further instructions.
