(B) She attacks her cousin.

The robotic arms holding her spread eagle released Randi with an almost **** whir. She rubbed her wrists and tried to think what to do. Looking in her cousin’s eye she knew there was no reasoning whit her. But what kind of choice was it - risk her beautiful melons or doom her best friend’s tasty tits. She looked to Daisy. The blonde’s blue eyes shimmered with fear.

Though that fear made her heart pound against her ribs, Randi couldn’t turn her back on Daisy. Rage filled Randi’s chest. Red hot, it pumped like fire through her veins. Look at what Sandi had done to her best friend, Randi let out a savage scream and charged her petite cousin. Her fingers like claws, she got one scratch in. A triple line of crimson streaked Sandi’s cheek.

But before she could try for the flat chested girl’s eyes, four robotic arms latched onto her limbs. Roaring like a tiger, she struggled against the metallic hands holding her. It was no use. They had her too tight, she’d never be able to break free.

Sandi gasped for breath, a hand pressed to her injured cheek. Anger flashed over her eyes and then was quickly gone. A cruel smile curved her lips. “Well, I guess that is a yes to the challenges. So, let’s get you set-up, shall we?” She clapped her hands and two more robotic arms swept down.

Each held a ring like that which Daisy wore. Randi screamed and thrashed against her restraints. Her large mammaries slapped from side to side and bounced wildly around. The robotic arms couldn’t catch her swaying tits. Randi laughed and doubled her efforts. The sound of her breasts painfully smacking against her echoed in the room.

Sandi snorted. “Smarter than I would have taken you for cousin.” Letting out a sharp whistle, she grinned at the overly busty teen. Again two robotic arms appeared. The slammed into the sides of Randi’s bouncing tits. The crushing pain stunned the red-head. Before she could recover the hands with the rings positioned over her nipples as a small apparatus extended from their centers, right through the middle of the rings.

Viciously, they clamped down on Randi’s nipples and slowly and painfully pulled her melons through the small loops. Ranid screamed and tried to fight back, but with the multiple arms holding her, she may as well have been a rag doll.

In short time, the rings popped against her chest wall. Her teats looked swollen, tinted red, veins starting to drift to their taught surfaces. Once satisfied the rings were locked in place, all the robotic arms released her. Immediately, she cradled her bosom and moaned at the painful pressure.

Sandi clapped her hands, drawing Randi’s attention once again. “Now, for the first challenge! Follow me.”

The small red head lead Randi over to the open door on the left side of the room. Beyond was a wide hall. Lining both walls in a stuttered pattern, strange devices protruded out at chest height. Sandi pointed down the hall. “All right, my big titted cousin, the first challenge is simple. Walk across this hall in under 3 minutes and you pass.”

Randi sneered at her. “I’m not stupid. What’s the real challenge?”

“No, really, just walk across the hall.” Sandi batted her eyes innocently. “Of course the path is through a gauntlet. But that shouldn’t be a problem.”

She patted Randi’s balled up left breast. “Or you could forfeit but now with the nano-wire on...” she left the sentence hanging.
