An Accident Waiting to Happen

She wasn’t moving.

“Katie!!” The naked redhead called again, shifting her weight from foot to foot as she strained at the edge of the track with stomach churning worry.

No no no! Wake up! Please! – You can’t be out there!

“Katie?!” Zoe tried with another helpless cry, whimpering when there was no response.

The redhead’s toes curled against the edge of the sand as she took another anxious look up and down the empty street, swallowed her worry and guilt and then rushed out towards the stricken blonde, her bare feet kicking up plumes with every frantic stride. Katie slumped dizzily to the side, her eyes flickering as her chest rose and fell in shallow breaths.

She’s alive!

Zoe’s heart exploded with relief as she drew close, “Katie?! Katie can you hear me?”

The blonde blinked several times, eyes refocussing, her face contorting for a moment as she came to. Zoe felt a creeping blush as Katie’s eyes widened at the sight of her naked breasts bouncing towards her, “Zo…?”

“I’m here – I –” Zoe stopped with a heavy knock as her outstretched hand collided with something in the air. Heart pounding, she glanced frantically between Katie and her hand, her other reaching out and colliding with the same invisible barrier at the edge of the cart. The naked girl recoiled, then reached frantically forward again, slapping desperately against the bubble encompassing the blonde with her palms. “I can’t reach you! Are you ok?!”

Katie rubbed the crown of her head, her eyes still numbly sweeping up and down Zoe’s naked body from the floor of the cart, her cheeks pink, “Y-y-yeah, I… I’m ok… I think I hit my head… I didn’t… expect it to move like that… Are you ok?”

Zoe blushed, bouncing on her toes anxiously as she glanced at the darkened neighbourhood again, “I’m fine! Y-y-you just missed me… It… tried to grab me…”

“I saw… I…” Katie let out a gentle groan as she carefully rolled her neck, “Help me up?”

“I… can’t” Zoe whimpered as she tapped the nothing, blushing hotter as Katie reached out a hand and frowned as her own fingers met the invisible barrier between them. She dropped her hand with a muted whimper, her eyes transfixed on Zoe’s exposed pussy before she tore her gaze away.

“Oh…”

To Zoe’s relief, the blonde pulled herself up into the seat, their eyes level as the unsteady vehicle rocked in place as she moved. It took a moment for Katie to blink and look around, her eyes widening, “I… I made it through the barrier?”

Zoe barked out a breath, her forehead dropping to rest against the nothing she was leaning against, practically hugging the barrier, before she nodded in quiet confirmation, “Y-yeah…”

Katie reached out to the air between them and tapped it experimentally, causing both girls to wince, “B-but there’s… another one?”

“I… think so?” Zoe whimpered, sweeping her hands left and right with guilty need. She couldn’t help but feel like Katie was somehow safe in the vehicle, while she was trapped outside of it, clinging to the edge of the blonde’s life raft while the track threatened to sweep her away. “Are you sure you’re ok?”

“I’m ok… I just hit my head Po… Zo!” Katie’s mouth snapped shut with a flustered blush as she clasped a hand across her mouth and squeezed her eyes closed.

Too distracted by her own frantic search for any kind of gap, Zoe experimentally traced the barrier with her hands; without thinking, she took a step towards the front of the cart, only for her foot to contact something slick and rubbery in the sand.

“Huh?” She glanced down, eyes widening in horror as a strap suddenly reared up like a snake.

Zoe shrieked on instinct, cold dread flooding her. She had no time to dodge the living tack writhing up from the sand, its tip ringed with black iron, and before she could blink the others around it did the same, fanning out in a writhing mass of black ropes that reached for her as one.

“No!”

The redhead yelped, trying to throw herself backwards and away but the first strap was quicker, snapping to a point at the waist of her harness, its connection instantly setting her off balance. Zoe grabbed at it in terror only to feel it smoothly but firmly recoil, dragging her protesting feet through the sand towards the cart front.

“Katie! Help!” Zoe shrieked with panic, helplessly trying to pry the strap from her harness as she was pulled away, the moment she was in range, a second strap took hold of another point on her harness, and then another, each adding to the slow but measured **** pulling her inescapably into position. “No! Let me go!”

“Zo!” Katie gasped, throwing herself at the barrier again, her hands banging in futile muteness against the air. “It’ll be – w-woah!” her words were cut off by losing her balance as the sulky started to pitch and sway with every wrestled jolt of Zoe’s fight.

The naked redhead felt the straps dodge and turn, snaking with devious and practiced precision to slide around her and snap into place. With every new connection Zoe felt an increase in some imperceivable weight tugging at her, pulling her as the mass of tentacle-like straps hauled the cart’s front up from the sand as it attached to her.

“Help me! I can’t – Gnngfh!” Zoe yelped frantically, her fighting reduced to more and more petulant kicks of her legs and wriggles of her torso as each new strap found its home. Zoe quickly found herself turned around, every strap of her harness now somehow an equal part of the mass on the cart, controlling and contorting her body until she was facing forwards between the draft arms, looking desperately back over her shoulder at Katie as the last of the straps slunk into position.

“It’ll be ok!”

Zoe’s fingers gripped with white knuckled panic at the straps, frantically trying to detach them from her harness as she stepped to-and-fro. Behind her she had the mortifying sense of the cart moving, its wheels spinning with her, following her every movement. With wide and **** eyes she gazed pleadingly back at the blonde as she grunted and squealed, snorting frantically at the inexplicably humiliating bondage she now found herself in.

“Let me go… please… please let me go…!” Zoe protested hysterically, her red hair and tail thrashing in unison as she writhed, helpless, floundering but held inescapably in place.

“Zo! Stop!” Katie pleaded, her voice quivered from the shaking vehicle and the redhead realised her every wild jolt of fight was being translated directly into the cart, causing it to bounce and turn violently, sprawling Katie across the handlebars.

“They’re on me!” Zoe shrieked, her body slick with dread as she stepped left, “It’s on me!”

The naked girl felt the piercing ringing fear in her ears, her heart beating in thunderous humiliation as she swallowed down the painful knowledge that she was harnessed to the cart – just like a real horse. Just like a real ponygirl.

She turned the other way, sending the cart behind her spinning on the spot, “I don’t like it…!”

“I know…!” Katie yelped, her voice soothing even as the cracks of her own panic broke through, “It’s ok Zo…! Just calm down! Stay still! Breathe!”

“They’re alive!” Zoe moaned, shaking her clenched fists against the straps again and thrashing the other way in a petulant attempt to break free, “Katie! D-d-do something!”

The blonde yelped as the sudden change in direction threw her across the cart’s seat, sending her careening into the invisible barrier on the other side. “I can’t if you keep moving!” Katie barked, her hands grabbing hold of the handlebars to try and pull herself upright.

GO!

The signal crashed through Zoe's mind faster than she could process what it meant. Her legs stepping forwards on instinct as she felt the familiar wicked white lash of the crop at her ass and the teasing hard tug at both her exposed nipples, directing her as her collar always had – Forwards.

Go. Now.

“W-w-wait!” Zoe gasped, her cheeks burning pink as she was unsure if she was pleading with her collar, or Katie or her own body’s reaction to it all. A mortifying, self-loathing embarrassment immediately erupted in her core as she took another step almost automatically – realising she’d stepped without wanting to, without really thinking, that the conditioning of the collar and all its whipping, and tugging on her helplessly exposed body had trained her to react first and think second.

Such a good pony!

“Wait!” Zoe tried again, louder, slowing her feet, only to feel the sting of the crop a second time – Run faster to avoid punishment!

Her legs turned, confused and dazed, she took another step forwards, bare feet landing with light footfalls on the dusty sand. Her harness shifted, the alien weight of the cart bared evenly through every strap as she felt its wheels turn behind her, like an animal chasing her, snapping at her heels.

“What are you doing?!” Katie yelped, trying to get her own bearings, as Zoe’s ass flashed white again with another beat of the crop.

“I can’t… please I can’t… it’s making me!” Zoe moaned, reluctantly increasing her walk to a trot as her eyes scanned the street in growing panic. With every pained and guilty step she was walking them further away from the house, dragging herself and Katie in the light cart further away from safety, further from home – and further into the terrifyingly eerie and empty unknown…

No no no no!

Far ahead, the signal at the end of the street cycled through amber to green as another distant rumble of thunder echoed from the spiralling clouds above.

“Just stop!” Katie pleaded.

“I can’t!” Zoe gasped back, her eyes glassy with confused guilt as she took another step and felt the crop again, the firmer tug at her nipples. The instruction was clear. “I have to!”

Ponygirls just run!

Zoe moaned, her feet churning through the sand, trembling and mortified as she found herself having to let go of the straps she’d been holding so tightly to increase her speed, feeling the disturbingly light weight of the cart settling across her harness as she pulled it with a disquieting lack of effort forwards with a humiliated grunt. Her trot became a faster walk, her bare body glistening as Zoe was **** forwards.

“Stop!” Katie demanded, her voice breaking with panic as another slap of the crop eased Zoe up into an unwilling jog. “Zo!!”

“I can’t!!”

“The railing!” Katie yelped back, causing Zoe to focus through the panic as she realised their line wasn’t straight and she was dragging them helplessly at an angled path towards the railing. Zoe moaned, whimpering as she attempting to control herself enough to just turn – and yet she couldn’t. She tried, only to earn a scolding tug on both nipples again and a rapid correction from the crop at her flank – Forwards!

What?!

“Katie!!” Zoe yelped, the impossible instruction to run at the fence turned her body aflame with panic and she whimpered, closing her eyes as the crop and the painful tugging drove her towards it…

Right!

Zoe turned; the instruction on her right nipple was painfully hard. Invisible fingers twisted it aggressively as she instinctively obeyed and threw her weight that way. She moaned, gasping as the unfamiliar lumbering of the cart behind her seemed to hold her back, dragging her whole body and making her normally agile turn feel sluggish and alien, like she was drifting as she ran.

Her left nipple, suddenly released by the molesting fingers bounced free, eeking another helpless gasp from the panicked naked redhead as she opened her eyes with a confused blink. They had avoided the barrier by a few feet, the cart swaying and skidding lightly through the sandy surface as it swung wide of her in the turn. Zoe trotted lightly on, her breathing shallow in worried breaths and legs still weak, as her head whipped left and right to take in the darkened neighbours houses as they passed.

“K-K-Katie?” She stammered, still moving obediently forward with another lick of the crop, even as she dared throw a pleading questioning glance back over her shoulder just in time to watch the blonde turn the handlebars gently left...

Instantly Zoe felt the familiar, soft teasing tug at her left nipple, the humiliating instruction impossible to ignore.

She turned gently left, cheeks burning as she obeyed and lined them up with the track again. Zoe gasped when she felt both her nipples teased in reward by the invisible molesters, her collar sparking into life with a mocking taunt,

“Good Girl!”

“Y-y-you’re…”

Katie gave her a sheepish, guilty stare as the realisation hit both of them, “I’m driving…!”
