The clicking starts as the mechanism engages. The blindfold prevents you from seeing it, but you know it's coming. You're still panting hard through your ring gag from the last cycle.
You're not sure how long you've been here, you tried to count the cycles in the beginning, but it wasn't long before your mind was too frazzled to keep track. You have no idea how much longer it's going to continue.
Your enforced strappado arch is accentuated by the cable connecting the harness around your head to the smooth hook lodged in your ass.
The belt slides upwards between drenched thighs. You don't exactly know what it is, but you know
intimately
how it feels. Some sort of rubber, firm but just slightly elastic. It's covered in soft, flexible little rubbery spines, and slathered in lube.
You totter from side to side a little on your ballet heels, making the long metal tassels clamped to your sore nipples tinkle gently. But you know there's no avoiding it. The belt presses upwards against you. The pressure forces it to flex as it insinuates itself once more between your lips, and the slick soft spikes are bent and crushed against your swollen inner labia. The pressure builds, and builds, making you grunt, and eventually It takes your weight and lifts you bodily off the ground.
You yelp, as have every cycle, at the too-intense sensations. You do your best to go limp, and hold your dangling legs still, knowing that the slightest movement will be transferred directly to your most sensitive area.
You are gradually lifted by the crotch upwards and backwards, til your torso is nearly horizontal. A padded strap around your waist keeps you centred above the belt. The strain is taken off your arms, and are able to rest your cuffed wrists against your lower back, but you're too preoccupied with the sensations between your legs to really appreciate it. The shifting of the distribution of your body weight causes your pussy to slide forward over the taut rubber belt. Sparks to go off behind your eyes as the insidious spines graze through your most intimate area, constantly flicking over your clit. You're unable to stop your hips from jerking, and your dangling feet wiggle ineffectually, which sets you to swaying gently from side to side, exacerbating the sensations. The tiny chains hanging from your nipples describe complex sparkling patterns beneath your dangling breasts.
Your weight settles and the wait begins.
A speaker comes on. You can hear in the distance women keening, squealing, wailing, grunting, incoherent begging. There are dozens of them, reverberating around the closed space, fading in and out. They're all you. They must have microphones in here, and they're playing back the audio from past cycles, mocking you. You do your best to block it out, but it's getting to you. You sound so helpless, so desperate, so passionate. Animalistic. So fucking hot.
They're definitely varying the wait time, making sure you can't predict when it will start, you can never relax. Never more than a couple minutes. Just long enough to keep you on tenterhooks -
The tension beneath you gives way completely, and you plummet... maybe 6 inches, before your momentum is abruptly arrested by the belt rocketing up to meet you again. The speakers simultaneously cut off, the better to capture your -
"AEEEIII - UH".
The initial impact is a wet, stinging slap, but your weight immediately forces it violently itself back between your lips. The momentum makes your rigid clit slide forwards forwards an inch or so through the forest of lubricated cilia. The white hot sensation makes your eyes roll back. Simultaneously, your head jerks, tugging up on the anal hook and causing the smooth, lubricated sphere inside to fuck up into you.
The belt has just enough flex and upward velocity to send you bouncing back upwards, though not quite as high as you started. Gravity quickly takes over, and you fall back down towards the belt, which has positioned itself slightly lower, and the process repeats.
The repeated bounces sink slightly lower each time, guiding your torso back towards it's original vertical orientation. Every jolt, pulse in your ass, and flash of slick prickly friction between your legs wrenches a guttural grunt or a squeal from you.
Every part of you is wobbling. Your legs kick frantically, your tits and ass wobble, your hair bounces wildly around your shoulders. The dangling nipple tassels jingle and tug painfully. It's frankly incomprehensible how they're even staying on.
You must look ridiculous. It's utterly humiliating, the sensations are overwhelming, and there's absolutely nothing you can do to escape.
You cum on the 4th bounce, wailing, whole body quivering. You have been forced to climax at least once on each cycle, but which particular bounce it occurs on varies. The bouncing continues, drawing out the orgasm, each jerk triggering additional aftershocks. It continues even as your orgasm ends, paying no heed to your incoherent tearful entreaties, remorselessly slapping against your overstimulated clit again and again, the sensations making you absolutely frantic.
After several dozen more bounces, once your torso is back to its original vertical orientation, it mercifully comes to an end. The belt slowly descends. Your outstretched toes graze, then contact the floor, but your legs are jelly, completely unable to support you. You remain perched with your full weight remaining on the belt, hunched over, shoulders heaving, trying to recover, jerking each time you move a millimetre and a rubber spine slides against your pussy. Rivulets of fluid tickle their way down your inner thighs.
Shortly the belt begins lowering again, tugging free from your inflamed, sore, thoroughly sensitised pussy. Strings of mixed lube and arousal stretch between them as it retreats.
You groan as the upwards pull on your wrists begins to put pressure back on your shoulders. You struggle to get wobbling colt-legs back under you and laboriously manage to lock your knees, standing back up.
