My slave was in trouble. Big trouble and he knew it.
My orders were clear, same as always, though that did not mean they were easy to follow. That was part of the thrill. I challenged Scott as he wanted to be challenged. He wouldn't have stayed, otherwise.
Earlier that evening, I needed to run to the grocery store to grab a few things. I had bathed Scott myself and oiled up his naked body. As my slave, his body belonged to me and he was permitted no privacy, even in his most intimate moments.
It was Friday night and I had had him in the plastic cock cage all week, denying his right to cum for five straight days.
These long trials without cumming got any easier for Scott, especially with all the sexual stimuli I continued to subject him too during the week. Even if he himself could not have release, he was still required to pleasure me whenever I commanded. With his mouth. With his hole. With whatever torment or humiliation I wished to put him through.
So when I freed him from the devilish device at long last, his balls were weighty and full, like ripe plums in my hand.
When I squeezed the base of his shaft, he grew hard almost immediately, his cockhead snaking up into the sleeve of my sweatshirt. He was ready to cum a bucket load, but he did not have my permission and I decided he could wait.
I put a handsome, black leather dog collar around his neck and a snug leather cuff around his balls to match.
Since I was going out, I commanded him to stand in the corner, facing the wall. There was a clear, glass buttplug screwed deep into his oiled-up hole and he was to stand spread eagled, hands behind his head, swaying his bubble buns until I got back.
With all the workouts I'd been putting him through, his ass looked better than ever. As round, pert and squeezable as freshly risen dough.
I liked to keep his bulbous buns moving and his hole stretched wide so it would be ready for my cock at all times.
The very sight of his perfect, moving buns had the power to unleash unbridled lust within me. I wanted him ready to be violated deep and hard whenever I got the urge.
Of course, I could have cuffed his wrists to his collar so he could not touch his long-neglected hardon even if he wanted to. But that would have been too easy.
He was my full-time slave now and this was his training. He would need to keep his hands away from his cock simply because I commanded him to do so. No excuses. If he disobeyed my orders, he would have to face the consequences.
"What are your orders, Scott?" I demanded, breathing down his neck.
"I am to stand here facing the wall, hands behind my head, bubble buns swaying, until my master comes home."
I made him repeat it two more times.
"What are you not allowed to do, Scott?"
Scott swallowed hard against his collar. A moan escaped his lips. "I am not allowed to move my hands or (gulp) or stop moving my bubble buns until my master orders me to. I am not allowed to touch my cock or cum until my master grants me permission." I could hear the pain in his voice, having to repeat that last line.
"Twice more, Scott." He recited his orders two more times.
I pressed my thumb against the glass buttplug so it slid still deeper into his hole, nearly disappearing between his fleshy, swaying cheeks.
He grimaced and groaned in discomfort. His big, throbbing erection flexed completely taut.
"You understand the penalty for disobeying me, don't you, Scott?" I said dangerously into his ear.
"Yes, master (gulp), yes I understand completely."
"Good boy." I raised my open palm and clapped it down hard on his dancing butt.
SMACK!
"UMF!" Scott went up on the balls of his feet. No matter how many times I spanked him, it somehow continued to catch him off guard and his reaction was always one of erotic surprise.
"You can move faster than that, can't you, Scott?" I punished his wiggling, round cheeks two more times, leaving them stinging and ruddy like the swell of a peach. Each punishment sent a lightning jolt to his ravenous cock.
"Are you going to sway your buns slowly or quickly while I'm out, Scott?"
"Quickly, master," he said, struggling to thrust his gorgeous backside back and forth as fast as he could. "I'll sway my buns quickly for you the whole time."
"That pleases me, Scott. Keep this cock or yours hard and dripping for me until I get back, won't you?" I gave his cock a vicious slap ("UMPH") then went out the door.
I hadn't even blindfolded him, which increased the danger that his mind would wander and he would lose his focus.
I had left him this way several times before and he had obeyed me without fail. If he managed to do as he was told (without touching himself) I rewarded him with a nice, long blowjob or handjob, or I allowed him to jerk off and cum while I watched (he was never allowed to masturbate when I was not present). All the semen that leapt out of his cock, he was required to swallow down again, in accordance with rule number six.
But never had I put him to this challenge directly after taking away his cum rights for an entire week. Never had I left him so desperate to shoot that big, hefty load I knew was weighing down his balls. I was asking a lot of him and I should have known he wasn't ready for the challenge. But I figured that even if he failed, he would learn his lesson for next time.
