As usual, she tested her bonds after he had finished tying up her legs. She could still wiggle her toes, but that summed up the extent of her freedom. Judging by the frantic contractions of her crotch rope and the accompanying moans, however, she seemed to be enjoying it. Time to put a damper on that.

Nina froze when she noticed he had picked up the dreaded muzzle gag. The flaccid balloon attached to the wide panel that would cover her lower face from nose to chin did not appear particularly daunting, but she knew better. She looked up at him with puppy eyes, but when she saw his determined expression, she opened her mouth with a resigned sigh. He patted her on the head.

“Good girl!”

Her eyes narrowed, but Robert just chuckled and fed the rubber bladder into her waiting mouth. Sorting through the mass of straps attached to the leather panel, he located the head harness’ main strap and tightened it around her cheeks until the mouth shield pressed firmly against her lips. He buckled the strap at the back of her neck, right below her ponytail, then surprised her when, instead of fastening the rest of the harness around her head, he attached the hand pump to the valve protruding from the panel. A few squeezes inflated the bladder in her mouth enough to immobilize her tongue, making intelligible speech impossible.

Nina was now reduced to endearing grunts and squeals. Just like the one she emitted when he dangled the pair of nipple clamps from their connecting chain in front of her eyes. Robert sat down next to her. She shrank back, but he would have none of her antics. His hand shot forward and grabbed her breast, his thumb and fingers pinching the rock-hard nipple between them. More squirming and squealing ensued. She was blessed with rather sensitive nipples.

“The more you struggle, the more I’ll tighten the clamps.”

His calm statement gave her pause. She was painfully aware that their mechanism was strong enough to drive the tips of their serrated jaws right into her flesh. After all, this was explicitly stated in the product description on the dubious darknet site where she had ordered the nipple clamps. An impulse buy she had probably rued a dozen times over.

Robert captured the nipple between the clamp’s jaws and began to turn the wingnut that closed them. The action was accompanied by subdued clicks from the integrated ratchet that prevented the nut from loosening on its own. He kept going until her nipple was flattened between the jaws. When he let go, Nina shook her upper body in an instinctive bid to dislodge the clamp. The movement set its counterpart at the other end of the connecting chain swinging. Although her nipple stretched with the increased pull, the clamp held tight. She hung her head. Until Robert relented, she was stuck with the clamp. Another fact that she had learned the hard way, but still had to reassure herself of every time.

“Tsk, tsk! What did I tell you? No struggling!”

She acknowledged her mistake with a muted whimper. Robert quickly attached the remaining clamp to her other breast. His eyes bored into hers as he tightened the clamps further. He constantly switched back and forth between both breasts to keep their bite at the same level of ferocity. Another full turn of the screws made her stare at him wild-eyed. He continued more slowly, spreading out the time between the ratchet clicks. Every new click made her shudder. Her nostrils flared as she braced herself for every new increment of her anguish. Watching her closely, Robert took a clamp in each of his hands.

Click! Click!

The two clicks sounded almost simultaneously. Her eyes widened dramatically, then screwed shut. Tears streamed down her cheeks. She threw her head back and arched her quivering body like a bow. A low, keening wail escaped her gagged mouth. Inadvertently, she thrust her breasts toward him as if begging him to tighten the clamps even more, but he recognized the telltale signs. She had reached her limit. The acute pain from her crushed nipples strained even her rampant masochism. It would take a moment for her endorphins to catch up.

Briefly, he considered loosening the clamps again, but he knew better. She might thank him now, but afterward, she would feel cheated out of the chance to prove her mettle. Besides, the wild tugging at her crotch rope suggested she had found a way to cope with the pain. Either that, or she was trying to saw herself in half. Indeed, it did not take long for her posture to relax and her moans to take on a subtly different quality. Smirking, he plucked at her nipple chain to get her attention. Her eyes snapped open.

“You should get your nipples pierced. Might not need the clamps, then.”

She snorted. But her automatic rejection lacked conviction. Her thoughtful look told him that the idea had taken root in her mind. She was probably enthralled by how some shiny jewelry would enhance her appearance, maybe thrilled by the possibilities nipple rings would open up for their play. In her aroused state, she might even be willing to consider the septum piercing he fancied. For the time being, he would have to make do with what he had.

He pulled on her nipple chain until he was able to clip it to the front ring of her collar with a snap hook. Nina moaned in pain as her breasts were lifted by her stretched, tightly clamped nipples. Really, she would be better off with the nipple rings.

“Lie down on your side! Back toward me!”

With her arms and upper body fused into one rigid unit, she had no choice but to slowly topple over. The jolt when her shoulder hit the mattress yanked at her trapped nipples and elicited a strangled cry. Nevertheless, she soldiered on and wormed around until she presented her back and latex-gloved arms to him. Her bonds had neither slipped nor loosened at all. He quickly went over them once more, making sure they did not pinch any neuralgic points. Nina had never reported any adverse side effects from his ropes, though.

Robert took the next length of wire and anchored it at her shoulder harness. From there, he threaded the wire between her legs and looped it around her ankle tie before returning it to her shoulders. He wrapped its free end around his hand for a better grip and started to pull.

“Arch yourself!”

Steadily at first, then interrupted by pauses to give her time to accustom herself to the mounting strain, he drew her legs up behind her. Nina greeted each further tightening of her hogtie with a groan, but he did not relent until her ankles were level with her wrists, forcing her body into a nice, tight arch.

Robert could not help but admire how the strenuous posture showed off her flat stomach and sleek legs. Incidentally, it also increased the tension on the chain that connected her nipples to her collar, which probably accounted for the tears pooling in her eyes. Although her hogtie was extreme by ordinary standards, he knew it did not really challenge her miraculous flexibility. He began to tie off the wire at her shoulder harness when she shook her head and mumbled into her gag.

“Ooh!”

“No? Too tight?“

“Ooh.” She shook her head no again. “Iheh!”

“Tighter?” he inquired incredulously.

“Mm-hmm!” Nina nodded her head enthusiastically, sending the loose straps of her gag harness flying.

“Wow!”

Her impetuous masochism surprised him again and again. He bent over to look into her face and see if she was serious. Her eyes sparkled with intense arousal and a hint of fear, but she met his gaze with a challenging stare. Okay, she was hell-bent on being pushed to her limits. He was happy to oblige, although she once again was topping from the bottom. Robert let her get away with it because her desire matched his own sadistic impulses. This time. He would have to break her of this habit eventually.

"Alright, it's your funeral. Don't think I'm going to untie you a second early for this."

Of course, there would be a time limit for her bondage. But it was his prerogative to set it. He undid the half-formed knot that anchored the wire connecting her ankles to the shoulder harness. Kneeling behind her, he braced her knees against his leg, then began to pull.

“Mmmmaiiih!”

Her drawn-out moan suddenly changed pitch as her feet approached her elbows. The hogtie forced her body into a dramatic bow, stretching her muscles and tendons to quivering tension. If he rolled Nina onto her stomach now, only her hips would touch the mattress. Robert cleared his suddenly dry throat when the eroticism of her plight caught up with him. He had been so focused on his rigging that he had almost lost sight of her, his willing subject. Now, her helplessness struck a chord deep within him. All the more so since, ultimately, she had brought it on herself.

His excitement added urgency to his movements when he quickly tied off the wire to complete her hogtie. Done! As a treat, he let his hands roam over her body. His fingertips slid over her thighs, then probed the taut muscles of her stomach, trying to sneak under the strands that constricted her waist. When they encountered the wire that bisected her mons pubis, he let it guide them to her hot, wet core. Her juices had seeped from between her pussy lips and soaked the entire region, giving him an idea of how turned-on she must be right now. With a needy moan, Nina fought her bondage to push her crotch toward his questing fingers. Robert chuckled and withdrew his hands.

“You know better,” he admonished.

The familiar script for their bondage games included additional steps, but she could not care less. She sighed exasperatedly and stepped up her own efforts, as evidenced by the increasingly frantic tensing of her crotch rope. If she had not provided her own lubrication, she would have rubbed her pussy raw for sure. Her thumbs were getting quite the workout. He made a mental note to check her latex gloves for wear afterward.

For the moment, Robert was content to just watch. Her struggles made for a fascinating spectacle. A smile played around his lips. He had a pretty shrewd notion why release eluded her, despite her dogged attempts to get off. Although the crotch rope was far from ideal, lack of stimulation was not the real issue: for Nina, the problem was a mental one.

He had played a dirty trick on her. From the start, he realized that her bondage fetish showed obsessive-compulsive traits. There were certain preconditions she simply could not do without. For one, bondage did nothing for her unless she was absolutely sure that escape was impossible. That had made self-bondage a difficult and dangerous proposition. Similarly, her bondage had to exude perfection. Anything she perceived as a flaw irritated her to the point where she could concentrate on nothing else.

“Rrrmh!”

Her growl interrupted his musings. Nina shook her head, attempting to direct his attention to the loose straps of the gag harness that flapped around her head. Bingo! He met her beseeching gaze with a reassuring smile of his own.

“Don’t worry, I’ll get to that.”

To be honest, they were not so different after all. The untidiness of her incomplete bondage bothered him as well. But his own obsessions compelled him to complete their established protocol first. Nina just had to simmer a little longer.

He retrieved the remote from the nightstand, turned on the TV, and flipped through the extensive catalog of movies stored on their home server. He needed to choose something that kept him entertained while she languished in her bonds. It was a given that she would not be released until the credits rolled over the screen.

At the beginning of their D/s relationship, in the heat of some silly disagreement over how much he got to ‘play’ with her while she was helpless, he had remarked that watching over her in bondage was as exciting as watching paint dry. Of course, that was complete nonsense then and now. He could never get enough of seeing her body writhe in tight restraints, of listening to her soft groans, smelling the scent of her arousal. Nina had never believed him for one second either. Nevertheless, his brazen lie had started the practice they now adhered to religiously.

Nina had laboriously inched her body around, so she could watch what he was doing with nervous eyes. Of course, the opportunity to play a little game was too good to miss. He deliberately made a show of considering movies notorious for their lengthy running times. Although there were a few of the overlong, modern blockbusters at his disposal, he quickly moved on to classic masterpieces.They both enjoyed films that were considered unusual for their age group.

“What do you think of ‘Lawrence of Arabia’, hmm?”

“Ooh!” Her panicked look was priceless.

“No? Thought you liked David Lean,” he teased.

‘Once Upon A Time in America’ and ‘Gone With the Wind’ each elicited a very satisfying whimper as well. Unfortunately, the rigor of her hogtie ruled out any of these choices. In the end, he settled on a film both he and Nina loved. With a runtime of 94 minutes, ‘Dr. Strangelove’ seemed manageable. But then, that was for her to find out, wasn’t it?

He started the movie and focused on Nina again. Only a few more steps to complete her bondage. She rolled her eyes when he presented her with the leather blindfold. By now, she was resigned to the fact that he never allowed her to watch while bound, to let her ‘concentrate on the experience without distractions.’ Still, she did not seem happy with his reasoning, presumably since, at some point, she became desperate for any distraction from her predicament. Too bad! At least, she would be able to hear the sound. Given that she was something of a movie buff and knew the screenplay of her favorite movies by heart, that allowed her to time her ordeal.

He placed the heavily padded blindfold over her eyes and buckled it at the back of her head. The previously skipped straps of her gag’s head harness quickly followed on top. He went over each of the many buckles several times and methodically tightened them until there was no more slack. Extending from the crown of her head to under her chin, the web of interlocking straps doomed even the most dogged attempts to expel the gag or dislodge the blindfold. She reflexively worked her jaw against its constriction as if to reaffirm this fact.

Once, he had left Nina like this for half a day, blindfolded and gagged, but free to roam the apartment with only her arms locked away in her armbinder. The experiment had been a smashing success. It had been highly entertaining to observe her desperate attempts to free herself of the hated restraints. None of them came even close to succeeding. In the end, a demoralized Nina gave up stumbling around blindly and assuaged her frustration by humping the furniture. He had ended the experiment then and made up with her through some conventional, but vigorous lovemaking. He also began to look into chastity belts, but so far, she adamantly refused to wear one.

At the time, he had not inflated the gag to its maximum capacity. With less than 90 minutes remaining, she would not be so lucky today. He reached for the hand pump still attached to the gag and gently squeezed, carefully observing the effects.The inflating bladder tried to push her jaws apart, which the harness forced closed. Nina stiffened in anticipation of the inevitable. Well versed in his ways, she knew he would not relent until the constricting straps of the head harness prevented any further expansion of the bladder in her mouth – with her chin and cheeks crushed between them!

He monitored her closely while he repeatedly squeezed the pump. Her cheeks started to bulge around the panel covering her mouth and the straps that held it in place. By his best guesstimate, the gag was about the size of an orange now. Despite her diminutive size, Nina had a generous mouth. And a sharp tongue! Hence, an effective gag was about the only way to get the last word in an argument with her. Fortunately, her tongue was not sharp enough to pierce the bladder that now pressed it to the floor of her mouth. Robert sighed wistfully. There were times when he wished he could keep her permanently gagged.

With her eyes gone as gauges for her level of distress, he had to find other ways to assess the effectiveness of her gag.

“Hum, when it gets too tight!”

Immediately, her soft whimpers turned into vigorous humming.

“Oh, come on. This just proves you’re still making too much noise.”

He squeezed the pump again, which quieted her down nicely. Her distended cheeks gave her the aspect of a chipmunk after a particularly successful foraging session. Perfect! He detached the flexible tube connecting the hand pump to her gag and patted her head.

“Nearly there…”

Only one more degree of freedom left to remove. The last piece of wire connected the ring at the top of her head harness to her big toes. He tightened it until her arched feet pulled her head back sharply and her breaths became labored, then loosened it again until her breathing returned to normal before he tied it off. Now, he could relax and enjoy the movie.
