"The best thing about heavy bondage is the power exchange. It's intoxicating, isn't it?"
The slave moaned with contentment. His Master loved reminding him of that. No matter how many times his Master said it, it always managed to drive him crazy. Sucking in air through the holes in his thick tight hood, the slave writhed in his tightly strapped leather sleepsack. No matter how hard he tried, his body stayed exactly where his Master wanted it. The slave couldn't move at all, not until his Master wanted him to move.
"Yeah, that's it. Struggle for me. Show me how helpless you are, slave."
The slave knew his struggling would turn his Master on; it always worked. He felt his dick grow and rub against the leather. He was only ever allowed out of his chastity cage when he was in bondage, and his dick was enjoying its freedom.
"Ha, look at you. Looks like you're really having fun in there. You have my permission to cum if you can manage it, but that doesn't mean I'm letting you out. You will be released only when I decide that it's time. Now, I know it's been a few months since you've been given an opportunity to cum, so I'll lube your dick up just to help you out."
His Master's words filled the slave with furious lust as he felt fingers spreading a cool slick gel across his erection. He began to grind vigorously against the inside of the sleepsack, but he just couldn't get enough friction to cum. He whimpered with pathetic frustration as he thrashed in the sleepsack, its leather creaking thunderously. He heard his Master click his tongue and chuckle.
"Ah shoot, that wasn't lube. That was the desensitizing gel. Sorry about that, boy."
Moaning in anguish, the slave could hear his Master's laughter. He wanted nothing more than to cum, to rip his arms out of the sleepsack and blast his load all over their bed, but the leather and straps held him mercilessly. His Master enjoyed the slave's helpless frustration, and that made the slave happy. He felt his Master's hands rubbing his leather-bound body, which only invigorated his struggles. His Master was right: the true beauty of bondage was power exchange. The slave surrendered control of himself, his body, his orgasm, and even his mind. The release of control made him feel free. The Master accepted that control and used it to make the slave squirm, which pleased the Master. Thus, the transfer of power fed this wonderful sexual cycle. Amid these thoughts, the slave began to tire and his struggles lessened.
"I wonder how long I should keep you here?"
This was his Master's favorite part. It was during this time, deciding the length of the sentence, that his Master felt most in control and the slave felt the most out of control. The slave had trained up his endurance during his many loving years in the service of his Master. Both he and his Master were well aware of his limits. The slave knew that he could potentially be here for a while. He felt his Master get into bed next to him.
"You know, I really just can't decide, so here's what I'll do. It's getting pretty late so I think I'll just sleep on it. In the morning, I'll decide when I think you should be released. I won't tell you when of course, but I promise it'll be before the end of the week."
The slave moaned with pleasure. What a hot fantasy to be trapped for days!
"You're probably thinking that’s just an exaggeration, aren't you, slave? Well, maybe you're right. But I would just like to remind you that we both have experience with long-term bondage. I know that we are both able to continue a scene for that long."
The slave heard the flick of a light switch and felt his Master get into bed beside him. He heard his voice near his ear.
"And if I did want to extend the scene, there would be nothing you could do about it. Think about this scene right now. We just planned on an evening of bondage, but I extended it to a whole night. What would stop me from extending it again?
That final question sent vibrations of excitement through the slave's body. He felt so totally under his Master's control that he began vigorously humping the inside of the sack once again.
"You certainly look excited. I have to admit, seeing you like this for a few days does sound pretty tantalizing. Maybe I will keep you sealed up for the rest of the weekend or maybe I'll just break my promise and keep you for the whole week anyway. You'll just have to find out. Goodnight slave."
The slave thought about being forced to spend the next few days in this leathery prison. The thought scared him and aroused him unbelievably at the same time. He continued to hump his numbed cock futilely against the leather. He thought endlessly about whether or not his Master was serious, but in the end, as his horniness and fatigue destroyed his mind, he realized that he didn't need to know. As his struggles subsided, he fully embraced the reality of their power exchange, as he had many times before. He would remain completely immobile and helplessly horny for as long as his Master wanted, however long that would be. There was no way to change that. This realization triggered a few more defiant thrusts before the slave finally tired and drifted off to sleep. He faintly heard his Master say one last thing before slipping away.
"Good boy."
