Mackenzie and Emma remain captives

The green leader ran her eyes across Emma and Mackenzie, enjoying the power she held over the once proud women immensely.

She drank in the details of their bodies, the curves of their thighs and hips, Emma's pierced and erect nipples, the sheen of sweat that still covered Mackenzie's skin from her streak across the field.

The two naked women stood timidly before her, their hands bound behind their backs and collars adorning their necks delicious symbols of their **** submission.

She could see the tension in their bodies, the way they fidgeted and shifted under the weight of the green mens' gazes.

With a sly grin, she considered how best to further torment Emma and Mackenzie, relishing the opportunity to embarrass them even further.

An idea occurred to her; by playing them off against each other and dangling the promise of freedom in front of them, it seemed likely that, with a little luck, she'd be able to manipulate the two naked captives into obediently following any command she could think of, no matter how humiliating or demeaning.

With a devious glint in her eye, she cleared her throat and stepped forward.

"We'd love to take you both with us, but sadly there's only room for one dog on our team"

Some of the greens looked disappointed, clearly happier now that a second attractive naked women had been 'recruited' to their team.

Emma and Mackenzie stood side by side, their eyes darting nervously between the leader and the audience of greens.

Listen up, everyone," she announced, her voice firm and authoritative. "We're going to make things interesting. The dog who proves herself to be the most obedient will earn herself a chance at freedom."

She watch as the nude captives exchanged wary glances. The promise of freedom hung tantalizingly in the air, a beacon of hope.

Consider it a contest," the green leader continued, a smirk playing at the corners of her mouth. "And we'll keep the loser with us until she learns how to follow orders like a good pet."

Around them, the assembled greens listened and nodded with approval as their leader explained how the naked women would be entertaining them all next.

"This is gonna be great" chuckled one.

The green leader could practically see the gears turning in Emma and Mackenzie's minds as they weighed the stakes of the twisted game. The desire for freedom at war with their instinct to try and preserve what little dignity they had left.

"First command," she said with a sadistic smile.

"Kneel."

Mackenzie hesitated for a brief moment as she processed the command. Then, slowly, she lowered herself to the ground, her knees parting ever so slightly as she struggled to remain balanced without exposing herself anymore than was strictly necessary.

Beside her, Emma didn't move.

"This is ridiculous. I won't play your stupid game." she snapped.

"Do as you're told, dog"

"Have some pride and stop humiliating yourself!" said Emma, directing her comment down at Mackenzie, kneeling meekly beside her.

Unperturbed, the green leader reached into the bag where she'd stashed Emma's clothes and drew out what looked like a lanyard with an ID card attached to it.

With a smirk, she held it up for all to see, drawing attention to her full name and workplace.

"Emma Morgan... wow, look at this. You're a PHD student." the voice called out, the tone dripping with malicious amusement.

"Hey put that away!" snarled Emma, she tried to maintain her frosty constructive demeanor but even Mackenzie could tell she was flustered by the greens knowing her full name and workplace.

With her free arm, the leader drew out her phone and snapped off several photos of the Emma.

"Stop that!"

Emma began to panic as she realized what had happened. Her identity had been exposed and suddenly her reputation was at risk of being tarnished forever. A cold knot of dread tightened in the pit of her stomach.

The green leader approached her, a predatory glint in her eye, and held out the phone for her to see.

"Starting to regret giving us all that little lesson on leverage and ****?"

The screen displayed one of the photos that the leader had just taken. It showed Emma in all her glory, her face, shaved pussy, and huge breasts (thrust outwards even more prominently by the binding on her elbows) were all clearly visible.

Emma fought against the cuffs holding her arms behind her back with renewed fury, **** to break free and smash the phone to pieces. Of course, the cuffs didn't yield and all she achieved was putting on a show for the assembled greens, her chest and ass wobbling hypnotically as she struggled.

Beside her, Mackenzie continued to kneel meekly on the ground, her naked body shivering in the cool air. She kept her eyes downcast, cheeks burning with shame, and prayed that Emma's defiance wouldn't land her in an even worse situation too.

Emma's mind raced as she tried think of what to do next, of what she could say to get out of her situation and back on the same side as the greens. Before she could utter a word, the green cut in, her tone harsh.

"Now, here's the deal," she said, their voice low and stern. "We know who you are, and we know where you work. And unless you want the whole world to know about... this, you're going to do exactly as we say."

Emma's blood ran cold as she realized the gravity of the situation. She had **** but to comply, to submit to their demands, to protect her reputation and her future career prospects.

"What do you want from me?" she asked, her voice still defiantly angry.

The green leader smirked, her eyes glinting with triumph.

"Haven't you been listening?"

She reached out and grabbed both of Emma's nipples with a fierce grip.

Emma cried out. She reflexively tried to pull backwards, away from the source of the pain, but the girl had strong vicelike fingers and Emma's nipple piercings made ideal grips to lock them around.

"Aaaahh! Shit that stings!"

As she tried to break free from the grip, her breasts and nipples stretched uncomfortably.

"I said kneel, bitch!"

As she spoke she twisted Emma's nipples roughly, sending sharp waves of agony through her chest, her eyes watering and her chest heaving as she struggled in vain to pull away

"Aaaah oouch! Okay! okay!"

Emma fell forwards onto her knees, a stream of colorful curses cascaded from her lips as she moved, language that might have made Mackenzie blush had she not already been crimson with embarrassment.
