There isn't enough cover for Mackenzie to hide behind

Mackenzie emerged gingerly from the hedge, careful to avoid scraping her bare skin again the surrounding branches, and saw that the twins had been telling the truth.

They were standing at the end of the long strip of land, dotted with bushes and patchy grass, that ran parallel to the park; a tall hedgerow divided the area where they stood from the rest of the park and shielding it from view.

"Maybe this isn't a bad plan after all" she mused to herself, blissfully unaware of what was soon to unfold.

The group set off at a leisurely pace, noticably slower than a normal walking speed.

"Could we maybe go a bit faster?"

Now that they were out in the open, Mackenzie's mind had begun to race again. Moving at such a slow place was torturous, her mind was screaming at her body to run back to the relative safety of the clearing. She could hear the people in the park just a few meters away from her on the other side of the hedge and knew that she might be discovered at any moment.

"If we go faster we might make too much noise and attract attention" retorted Mike in a condescending tone that made it clear he thought she was being completely ridiculous.

They traveled in single file with Alicia at the front, Mackenzie in the middle, and Mike at the back.

From her time with the tans, it had become painfully apparent that men seemed to be particularly interested in checking out her curvaceous rear end. Mackenzie had never thought she had a particularly impressive butt, it was perky and nicely rounded but she'd always been self conscious about it and worried that she carried slightly too much fat across her cheeks and upper thighs.

However, it had proved to be very popular with her captors today and had recieved the same amount of attention as her boobs. She winced as she recalled the numerous spankings, rough squeezes, and cries of "nice ass!" she'd been subjected to. Far too much attention for her liking.

It was therefore no surprise that Mike had decided to walk at the back of group and treat himself to a view of the redhead's bare ass swaying from side to side as she walked. He didn't make crass comments or slap her tender cheeks as too many others had done today but Mackenzie still burned red with embarrassment.

It was so much worse now that someone she knew was looking at her naked. Even worse, she was pretty sure that Mike had had an adolescent crush on her all those years ago and silently prayed that this was no longer the case. "He's probably imagined me in the nude before and now he's got front row tickets to the real thing!". Mackenzie sighed, flexed her wrists against the cuffs, and tried not to think about how much he must be enjoying her predicament.

Thinking about Alicia did nothing to calm her nerves either. The girl seemed completely unsympathetic to Mackenzie's situation. If anything, it looked like she was relishing the experience of having so much power over her former babysitter. Mackenzie could see that the girl had her phone out and was fully engrossed in it, typing away as she walked. If someone appeared in front of them, Alicia certainly wouldn't notice in time to warn her and spare her the shame of being seen by yet another person.

After several more minutes of painfully slow progress, Alicia came to a sudden halt.

"Sorry Mackenzie I forgot about this bit"

The luckless redhead looked where Alicia had indicating and saw to her dismay that the high hedgerow came to an abrupt end and was replaced by a low line of shrubs that barely protruded three feet above the ground. If she kept waking, she'd be clearly visible to everyone in the park. She could still hear people talking and laughing on the other side of the hedge.

"I guess we're going back then" said Mackenzie, turning to head back the way they'd come. Realizing too late that Mike was standing directly behind her, the naked woman collided with the boy, the soft warm flesh of her bare body pressing lewdly against his fully clothed frame.

She immediately leapt backwards away from him, stifling a squeal of embarrassment as she did so.

"No! We've come too far to turn back now!" said Alicia, unwilling to abandon her plan.

"I'm sorry but I can't be seen like this!"

"I bet if you crawled on your hands and knees you'd be low enough to the ground to stay out of sight" interjected Mike.

"Yes that's a great idea! Then it'd just look like me and Mike are walking alone!"

Mackenzie balked at the suggestion. Did these two honestly expect her to do that?

"That's ridiculous! Anyway, even if I wanted to do that I can't crawl with my hands stuck like this" Mackenzie twisted to the side and wiggled her bound hands at the twins. Once again causing her plump round tits to jiggle back and forth.

"That shouldn't be a problem for long!"

Alicia beamed with pride and pulled a hair clip from behind her ear. She walked behind the restrained redhead and began to fiddling with the lock on the cuffs again.

It seemed suspicious that Alicia had suddenly remembered she could pick the lock and hadn't thought to do so earlier when she'd taken a look at the cuffs but Mackenzie kept quiet (she had learned her lession, and decided that this time it wasn't worth risking annoying the people who had a lot of power and leverage over her).

Moments later, the handcuffs sprang open. Relief washed over Makenzie. She took a moment to rub the sore skin of her wrists before firmly clamping her newly liberated hands across her chest and crotch. It felt so good to have the use of her arms back after so long!

While awkwardly crossing her legs, she removed the hand covering her crotch and attempted to open the buckle holding the collar onto her neck. It was as Alicia had said, the mechanism was stiff and refused to budge.

"Okay now down you go Mackenzie" said the girl, pointing to the ground at her feet as she spoke.

"Are you sure there isn't another way? It's just pretty embarrassing for me to have to crawl while I'm still not wearing anything"

She'd only just regained the ability to cover up with her hands, it seemed horribly cruel that that boon was almost immediately going to be taken away again.

'I don't know why you're embarrassed! It's not like we haven't seen everything anyway" replied Alicia with a sneer.

Makenzie blushed at this but was too flustered to think of a counterargument.

"Now stop wasting time and do as your told" ordered the girl, a new tone of authority present in her voice.

Mackenzie reluctantly obeyed. She tried her best to preserve her last shred of dignity by keeping her legs tightly clenched together as she sank to her hands and knees. Once again, the naked woman was unable to keep any part of her covered up.

"That's perfect! You just need to stay low and no one will see you!"

Clearly, Alicia was still very pleased with herself for coming up with the plan to get Mackenzie back to the house and didn't see this latest development as a problem.

Now eye height to the twins' knees, the luckless redhead shuddered as she imagined the view she must be presenting; her size C tits hung beneath her, her curvaceous rear-end stuck out behind her and, though her legs were clamped tightly together, she could tell that her pussy lips were still partially visible to anyone viewing her from behind.

Beyond all that, there was something particularly humiliating about having to crawl while the twins remained upright and proud.

From her low position, Mackenzie looked up at Alicia and saw that she had picked up the loose end of her leash.

"I don't know if it's necessary for you to hold onto that" said Mackenzie. She made eye contact with the girl standing over her. Alicia smiled down at her and she immediately looked away, unable to maintain her gaze. It was simply too mortifying to have this conversation with the younger woman while fully nude and down on her hands and knees.

"Oh Mackenzie, your leash will get awfully dirty if I just let it drag along on the ground and you don't have a free hand to hold it with! " the girl smiled as she spoke.

"Is she doesn't want us to hold it for her, she could hold it between her teeth?" suggested Mike.

Mackenzie took a moment to contemplate if she'd rather have Alicia hold the leash for her or carry it in her mouth and decided to go for the former. Both options were unspeakably degrading but something about having the damn thing in her mouth felt particularly disagreeable. The fact that Mike had made the suggestion suggested her that this was something he was keen to see and would get off on.

"No that's alright, when you put it like that I think it's best if you hold onto the end for me"

Alicia crouched down in front of the kneeling Mackenzie and gave her a condescending pat on the head. "Don't worry, I won't lead you astray!" laughed the girl, amused by her own wordplay.

Mackenzie wasn't sure what to think, the teens were helping her but they also seemed to be having far too much fun ordering her around and making light of her situation. She also didn't like how the girl had referred to it as 'her leash'.

"Let's keep going! If we stay still too long someone might see us!" said Alicia, tugging on the leash as she spoke.

Mackenzie flushed red with shame and began to crawl forwards. She tried (and failed) to think of a more abasing situation than being on her hands and knees completely naked and having to crawl through the undergrowth while a girl she use to babysit held the end of her leash.

Alicia was still leading the group and continued to set an agonizingly slow pace.

As she crawled, Mackenzie glanced left and right repeatedly, keenly aware that she was in a public space and someone could discover her at any moment.

"You're doing great Mackenzie!" said Mike from behind, an entirely unwelcome reminder that the young men was enjoying an unobstructed view of her from the rear.

She gritted her teeth and continued to crawl. The metal loop on her collar clinked lightly. She could feel her hanging breasts freely swaying from side to side and her round ass wobble left and right as she moved. Her pussy lips felt horribly exposed; this was worse than when the tans had blackmailed her into bending over and spreading her legs for them.

Mike was undoubtedly getting a great view of her crawling along the ground in all her glory, Mackenzie tried not to think about how he now had a very clear idea of what she must look like while having sex doggy style.

"How much further do we have to go?" she asked, hoping for good news.

"Sorry! We're not even halfway there yet!" replied Alicia, looking down at the nude woman crawling along the ground beside her and trying hard to not give away in her voice how much she was enjoying Mackenzie's embarrassment.
