To avoid misconceptions: This is obviously a fetish fairy tale, not a realistic depiction of a loving BDSM relationship based on SSC principles. If you're uncomfortable with stories featuring outré fetishes like permanent bondage, piercings and slavery, I'd suggest to skip this tale.

By now, her appearance matched her mental image of the perfect slave girl much more closely, yet there were still discrepancies. She instinctively shied away from thinking about them, frantically trying to flood her mind with memories from harmless childhood days instead; anything to drown out the unbidden images conjured up by her supercharged libido. Scenes from carefree summers spent playing with the kids from the neighborhood repeated before her mind's eye. She fondly remembered that "Cowboys and Indians" had been a favorite, yet in hindsight, it maybe was a little odd how often she'd ended up tied to a tree ...
'Oops!'
In panic, she scrambled to summon up some less dangerous memories. Her first boyfriend, for example, had been sweet and caring. He would never have done anything to hurt her,
unfortunately
. Such a pity that he'd been so clearly out of his depth when he found the handcuffs she had 'accidentally' left lying around. Since he had been puzzled by the simple cuffs then, how would he react if he saw her now? Or worse, adorned the way she was supposed to be ...
'Fuck!'
Apparently, her desperate efforts were doomed to fail. Ordering herself
not
to think about something invariably provoked the exact opposite result. Maybe it would be for the best if she ceased her futile evasive maneuvering and simply embraced her inevitable fate. After all, it were her own secret fantasies that would shape it. Despite the voice of reason screaming at the back of her mind to stop, she succumbed to her irrepressible desires and once again turned towards her favorite stories, in which slave girls were not only helplessly enchained, but also adorned with extreme piercings that rendered them even more controllable.
The metal rewarded her renewed compliance with the desired mode of thinking with a spike of pleasure that made her gasp. Analogous to what it had been doing to her arms, it had put her mind into something akin to a mental ratchet that propelled her down the route to an ever-deepening enslavement. She saw through its tactic, yet could not change course regardless.
"Aiih!" Lin screamed into her gag when both of her breasts were perforated horizontally behind her nipples, through the areolas. This was accompanied by an intensely stinging sensation that quickly subsided since the metal was working its magic to dampen the pain. Not that Lin would greatly have minded the pain, being as filled with masochistic bliss as she was. The metal quickly enlarged the piercings, then formed grommets within the wounds while simultaneously healing and strengthening the tissue surrounding them. Two thick rods filled the openings and were immediately complemented with sturdy U-shackles that outlined the lower halves of her nipples.
Next, she felt her lower lips grabbed and stretched. In rapid succession, each of her outer labia was pierced five times and the resulting holes immediately fitted with more of the wide-flanged grommets. Of course, the grommets were not left unoccupied for long but soon played host to sturdy bolts joining her lips to the protective shell that covered her pussy, splaying her sex wide open. Unfortunately, that was not all.
Forced to go ever deeper down the rabbit hole of her masochistic fantasies, Lin moaned in dread when she felt a tight metal collar clamp itself around the base of her clitoris. As it turned out, her fears were well-founded, when a thick metal pin speared through her compressed flesh and thus irrevocably anchored the collar to her body. Adding insult to injury, another U-shackle formed on its outside, turning her forcibly lengthened, sensitive nodule into the fastening point for a most intimate leash. Although only some unseen hook snagged the shackle and locked it to her chastity cover for now, the persistent, irritating pull on her clitoris acted as a disconcerting preview of future woes.
All her new piercings throbbed in time with her racing pulse, yet apart from the initial spike of pain when her flesh had been perforated, Lin was spared from any more serious discomfort. Within seconds, the metal repaired the damaged tissue, integrating the grommets into it as if they had always been part of her body. Consequently, there was no lengthy healing period to consider before her Mistress could make full use of her new attachments. It also meant that the metal could continue its assault indefinitely without endangering its victim's physical health. Albeit Lin's mental well-being was a different matter.
