Tick-tick-tick-tick

She moans, squirming as the gear clicked another notch along. The grinding of the teeth together mirrors her grinding against the chair she's tied to. 

She gulps as she watches the gear turn notch-by-notch, feeling her arousal levels rise as it does. She knows that once it makes a full rotation, she'll cum and the cycle will start again. She is eager to, but the slow inevitable march of heat throughout her limbs makes the anticipation maddening, dreaded.

A sharp gasp as she feels her heart pounding through her body, a flush working its way up her naked chained-up form as she cums strongly. She shivers, twitching and biting her lip as her thoughts are scattered like leaves in the wind.

Shaking her head, she regathers her thoughts into some semblance of order and glances over towards the line of gears, intent on finding the last one in the chain of gear after gear after gear. She remembers being told that the gears would stop when the last gear made one full rotation, and though she hasn't been able to keep track of time, she thinks it's already been a while.

Surely the last gear is at least halfway rotated, right? She's had more orgasms than her mind can count.

Tick-tick-tick-tick

The primary gear, now nearly full rotated, sends a pulse of pleasure through her so strong that she nearly cums in that instant. Only the magic of the gears, ensuring she will cum when and only when the gear rotates another time, stops her.

The gear that governs her peaks of pleasure rotates with a loud, satisfying noise, and she's lost.

After an endless moment of whimpering and arching her back and crying out in heat and animalistic mindless lust, she gathers her thoughts enough to look over at the gear at the very end.

It hasn't moved.

Her eyes widen and she glances down the line of gears, desperation lending her mind swiftness. 10 gears, each with 24 teeth. The first one fully rotates 6 times per minute, turning the gear that makes her orgasm one notch each time. The gear that makes her orgasm fully rotates every 4 minutes, a quarter around per minute. The next gear rotates one notch every time the orgasm gear completes a rotation, amping up her pleasure to even greater heights whenever it completes a cycle-- 24 times 4 minutes, 96 minutes, an hour and a half.

She breathes out an almost tortured moan as another orgasm shocks through her, shattering the train of her thought before she regathers it. Shakily, she resumes her process.

The first gear rotates fully every 10 seconds.
The second gear rotates fully every 4 minutes.

Tick-tick-tick-tick

The third gear rotates fully every 96 minutes.

The sweat slicking her skin is a combination of heated arousal and nervousness now as her mind works frantically.

The fourth gear rotates fully every 96 times 24 minutes, or every 2304 minutes...

Every 38 hours.

The fifth gear...

38 days.

There are 10 gears

Her mind shatters again as the third gear turns over one notch, and every gasp of pleasure becomes sharper and stronger. Each pulsing heartbeat sends floods of pleasure through her veins as the ticking continues.

She focuses blearily on the third gear and registers that it's moved 3 notches since she was tied up.

The last fragments of her mind tell her that means she's been here for nearly 5 hours.

Every time the third gear ticks over a notch, the pleasure increases, or so she was told. And it's already this much.

Tick-tick-tick-tick

She begins to moan, a keening sound that she can barely tell is coming from her own mouth.

Another orgasm rips through her and her whimpering and crying reaches a fever pitch.

Tick-tick-tick-tick

She's panting, desperate, tongue hanging out of her mouth, drool dripping onto the floor. Her chest heaves with every breath.

As the next towering peak of pleasure overwhelms her, she lets her mind float away into the gears.
