A jump rope

Mackenzie gasped and turned to run when she realized what the boy was holding.

She didn't make it far. The Green leader caught the trailing end of her leash and used it to bring her to heel almost immediately. The naked redhead struggled to break free but to no avail. The leader was too strong; if she pulled any harder, she'd **** herself with the collar locked around her neck.

"Where do think you're going, dog?" teased the girl.

"Anywhere but here!" thought Mackenzie.

By then, the boy who has disappeared into the shed had rejoined the group, still brandishing the object he'd gone to retrieve.

"Like I said, we've checked the bells stay on when she moves side to side. We can use this to make sure they don't fall off when she's going up and down!"

It was a jump rope. They weren't seriously going to make her jump up and down completely nude with bells dangling off her tits were they?!

'You're a genius!"

"Okay, I need two volunteers to help run the test"

Apparently they were.

Almost all of the Greens' hands shot up, they all wanted to have a direct hand in embarrassing their captive even further.

The leader selected two of her comrades and beckoned them forwards.

Mackenzie locked eyes with the Green leader, "please don't make me do this!"

The look of glee on the girl's face was unmistakeable.

"Be a good dog and do as you're told"

Mackenzie felt anger build inside of her. Wasn't it enough that she was naked, handcuffed, and on a leash? Wasn't it enough that she'd already been humiliated and put in her place? Did this girl really have to clamp bells to her nipples and **** her to jump and jiggle around like an obscene naked jester?

The leader began to twirl the largest heavier sleigh bells around her finger playfully, the threat was unmistakable:

"Do as you're told, or things will get worse for you" said her eyes.

It was hopeless. She couldn't escape right now do antagonizing her captors would be pointless. Sick with dread, Mackenzie knew she'd have to do what they wanted and hope another opportunity to escape presented itself soon. She prayed it wouldn't take too long.

The two Green volunteers each took an end of the jump rope and stood either side of their naked captive.

"If the bitch can do 20 jumps in a row without losing a bell, I'd say that's a fair test of them. Wouldn't you agree?" Said the leader.

Whooping and a wild applause filled the air.

Mackenzie looked at her audience and felt the acute embarrassment at seeing their delighted anticipating faces. They weren’t just seeing her nude body, but they were forcing her to perform for them.

She blushed. If she had been told any other day that she would be doing naked jump rope in front of a group of strangers, she would have never believed it. But after everything that had happened today, she had reached a point where almost nothing could surprise her. Sadly, not being surprised did nothing to quell the embarrassment she felt.

"Time to make sure those bells aren't going anywhere," the Green leader teased. "Start jumping. Now!" she commanded.

Mackenzie gritted her teeth and turned to faced her audience. She stood with her legs together, arms still locked behind her, and took a deep breath. "I have to do this", she told herself.

The teens began to move the jump rope in a slow arc downward towards her feet. Mackenzie started jumping, taking care to push off the ground as gently as possible so as to clear the rope while minimizing the effect inertia and momentum had on her body.

Hop.

Hop.

Hop.

It was wasted effort.

Her generously proportioned tits followed the motion of her body, enthusiastically jumping up as she left the ground, and violently dropping back down as she landed on the floor. The bells began to chime in time with her movement.

Hop.

Hop.

Hop.

It was agony, both physically and emotionally.

The grip of the clamps was crushing her nipples. Her breasts bounced around wildly, the bells forcefully tugged at her nipples with greater and greater ****.

The teens continued to move the rope in an arc, Mackenzie continued jumping over it.

Each time she landed back in the ground the bells plunged downward remorselessly, stretching her tits until they recoiled back to their natural perky state.

"I must look ridiculous" thought Mackenzie, blushing with shame, as she felt her tits, thighs and ass jiggle wildly.

Hop.

Hop.

Hop.

"Man screw twenty, I want her to keep doing that till she gets to a hundred!"

The naked woman's bouncing body was quite an entertaining sight, and her audience cheered and laughed at the hilarious show she was putting on. Some of the teens began to move behind her, preferring to take in the view of her shapely ass as it wobbled up and down.

"Man I could look at that ass all day"

For Mackenzie, it was without doubt the most demeaning experience of her life. For the boys watching, it was the most excitingly erotic thing any of them had ever seen. The bells continued to chime as they rose and fell in time with her bouncing breasts.

"I could look at those tits all week!"

Mackenzie tried to stare at the fence behind everyone, ignoring the thunderous cheering and the grinning faces of her audience. She was so focused on attempting to block out the reality of situation she didn't notice that several of the teens, eager to create a permanent record of her shame, had taken out their phones and begun to photograph and record her.

Hop.

Hop.

Hop.

She had no idea how many jumps she'd made, but it felt closer to a thousand than twenty. The humiliation of the laughing and cheering crowd was overwhelming.

As she bounced up and down in utter humiliation, she looked to her left and briefly made eye contact with one of the boys watching her. He smirked and gave a small nod to show his approval of the show she was putting on. Mackenzie squeaked with embarrassment and quickly averted her gaze. She felt degraded and disgraced, and hated herself for meekly going along the the group's demands.

The teen in question then took out his phone and made sure to get some closeup shots of the captive redhead's pinched nipples and bouncing breasts.

"Faster bitch!"

The teens holding the jump rope began to move it faster, forcing Mackenzie to hop up and down more frantically.

Hop!

Hop!

Hop!

Hop!

Hop!

It was too much. The exposure, the jumping, the clothespins.

Hop!

Hop!

H-

Suddenly, as it whipped into the air, one of the clothespins lost it's grip on her chest; the attached bell arced through the air, pin trailing behind it like the tail of a comet, before landing on the lawn with a muted metallic clink.
