Kirsten is now completely compliant to her owner’s will and is sent on her first mission - the recovery of Maria, whose blackmailed sexual slavery still holds her captive.
After rescuing the hapless girl, the training of both women continues while the rebel band seeks to discover the fate of their comrade. Once successful they try to mount a rescue before the officer breaks her will and renders her an obedient servant who is lost to them forever.
A race against time ensues between the forces as the officer uses ever more fiendish and cruel torments and pleasures to render the girl a submissive pet, the expert training making it uncertain whether she will turn on her owner or her friends when they come for her.
From the hidden regions beyond the black steel walls another site of restraint had been brought into view, the mechanized torture chambers hiding their apparatus from her until the Mistress called them from their recesses. Kirsten briefly wondered what other nightmarish contraptions hid behind the secret doors about her and then turned her attention to her current mechanical adversary.
A telescopic steel pole had hydraulically ascended to a height roughly comparable to the middle of her back. At the summit another metal pole had been riveted horizontally into place to form the cap of a steel ‘T’. At the base, two telescopic poles lay curled back into the steel upright, each ending in a stern metal fetter that hovered a few inches from the ground.
Set back from the pole were two rings in the floor from which steel cable sprawled to connect to a heavy shackle, the weighty devices open and hungry for female flesh.
The Mistress brought Kirsten over to this strange device and removed the leash. Grabbing Kirsten by her hair she used it as a new lead by which to deliver her into the arms of the creation.
“Come on, slave. You’ve got more lessons to learn if you truly wish to be mine,” she purred, her eyes briefly flitting across Kirsten’s smothered form, the glance a decidedly licentious one.
Kirsten’s back was delivered to the highest horizontal pole and her arms lifted over it so that it pressed against her shoulder blades. The Mistress took hold of her ankles and brought them into the fetters. The cuffs instantly snapped shut to her extremities and then inflated from within. The rubber interior swelled with pressure, causing them to grab even more firmly to her flesh.
The wrist cuffs were collected and snapped to her, the interior billowing and compressing them as well, leaving her arms attached to distant anchors in the floor.
“Are we ready, slave?” asked the Mistress, standing before Kirsten, her eyes scrolling up and down the helplessly captive form.
“Yes, Mistress,” whispered Kirsten, suddenly afraid of what rigors awaited her. The bondage was obviously ready to intensify drastically at the merest touch of a button.
Opening a control hatch in the wall the woman flicked a switch and brought life to the assembly. Kirsten’s breath accelerated rapidly as the ankle struts began to elongate, forcing her legs outward, turning themselves into a most stringent leg spreader that had her inner thighs churning with strain.
The upright began to rise, digging the horizontal pole into her upper arms and lifting her from the floor. Kirsten croaked and bit her tongue as she was hauled into the air, the cables snapping taut and stretching her arms out. The machine slowed and continued to move in smaller increments, racking her body as the observing Mistress ensured she was gratuitously stretched.
