The ambient noise level in the workshop had reached 75 decibels, which Kaito noted was precisely the threshold where sustained exposure began to cause cognitive fatigue.

  On the left side of the room, Era was attempting to draft a "Provisional Mandate" on a rickety wooden crate, her fountain pen scratching aggressively against parchment. On the right, Xenia was sharpening her serrated bck-iron bde with a whetstone, the rhythmic scree-ching sound designed to be as irritating as possible.

  "The frequency of that stone is vibrating the brass leads on the chair, Xenia," Kaito said without looking up from his soldering iron. "If you misalign the sensors, I’m charging you for the recalibration time."

  "And if she doesn't stop that incessant grinding, I’m going to have her arrested for disturbing a government official," Era snapped, her silver hair shimmering with static. "Kaito, this environment is unacceptable. How am I expected to forge a High Council document with a... a thug breathing down my neck?"

  Xenia stopped the whetstone and leaned back, her amber eyes glowing in the dim light. "The 'thug' is the only reason your throat hasn't been slit by a Guild assassin on your way out of the district, High-Born. You’re lucky I’m letting you breathe my air."

  "Your air?" Era stood up, her silks rustling with indignant magic. "This is a Royal District by decree! Technically, your very presence here is a viotion of the 4th Statues of Urban—"

  "Enough," Kaito interrupted. He dropped a heavy brass casing onto the table with a loud cck. "Both of you are emitting high-density stress signatures. Era, your mana-vessels are already starting to cloud again. Xenia, your core temperature is rising. You are currently feeding into each other’s inefficiencies. It is a feedback loop of wasted energy."

  Kaito stood up and adjusted his spectacles. He looked at the two women not as companions, but as two high-pressure boilers sharing a single, poorly-rated steam pipe.

  "The Restoration Chair is cooled and ready for a Tier 2 cycle," Kaito continued. "However, we have a scheduling conflict. Era needs the session to maintain her bureaucratic focus for the mandate. Xenia needs the session to stabilize her combat reflexes for the night patrol. I have one chair. I have two clients. And I have exactly four hours of power left in the auxiliary crystal."

  The room went silent. The rivalry, which had been purely verbal until now, suddenly acquired a physical stake.

  [Business Management Alert: Resource Scarcity Detected]

  [Objective: Resolve Scheduling Conflict without Asset Loss]

  "I am the Magistrate," Era said, her voice dropping to a dangerous, low hum. "My needs are a matter of state security."

  "And I’m the one holding the bde when the Guild comes back," Xenia countered, her heavy, ste-grey shoulders tensing with predatory agitation. "My needs are a matter of his security."

  Kaito looked at the chair. He looked at the 150 Data Points he had banked. He looked at the 'Biological Feedback Sensors' blueprint, which was currently at 15%.

  "There is a third option," Kaito said, his voice ft and clinical. "The Mk. I Chair has a secondary grounding rail. It wasn't designed for two occupants, but the surface area of the leather is sufficient if the participants are... ergonomically aligned. I can run a Tandem Calibration. It will bleed the excess intent from both of you simultaneously into a shared feedback loop."

  Era’s face went pale. "Shared? You mean... at the same time? In the same seat?"

  "Technically, you would be acting as each other’s heat-sinks," Kaito expined, picking up the jar of conductive gel. "Xenia’s high-temperature output would draw Era’s congested mana out faster, and Era’s frost-signature would prevent Xenia’s core from red-lining. It is a 22% increase in efficiency. However, it requires total skin-to-skin contact to maintain the circuit."

  Xenia’s predatory grin returned, wider than before. She looked at the horrified Elf and then at the chair. "Skin-to-skin, huh? I’ve always wondered what a Magistrate tastes like when she’s melting."

  "I... I absolutely refuse!" Era stammered, though her knees wobbled as a fresh spike of mana-pressure hit her temples.

  "Refusal is an option," Kaito noted, opening the jar of blue gel. "But at your current rate of congestion, Era, you will be catatonic by midnight. And Xenia, your bde-arm is already shaking. You won't survive a fight with Thorne’s enforcers in that state. The math is simple: Colborate, or fail separately."

  The logic was the only thing that could bridge the gap. Ten minutes ter, the air in the workshop was thick with a different kind of tension.

  Kaito had stripped the chair of its headrest to provide more room. Xenia sat first, her massive frame filling the seat, her dark skin glistening with a fresh yer of lubricant. Era was then forced to sit between Xenia’s spyed legs, her back pressed firmly against the Hobgoblin’s chest.

  "The contact must be continuous from the cervical vertebrae to the sacrum," Kaito commanded, his hands moving with professional indifference as he guided Era’s posture. He applied a thick yer of gel to the junction where their bodies met, his fingers sliding between the Elf’s shoulder bdes and the Hobgoblin’s pectoral muscles.

  Era let out a strangled whimper as Xenia’s arms wrapped around her waist, pulling her flush against the ste-grey muscle. The contrast was vivid—Era’s pale, porcein skin against Xenia’s rugged, bruised-earth tone.

  "Your heart rate is 110 beats per minute, Magistrate," Kaito observed, checking a gauge. "Try to synchronize your breathing with Xenia’s. You need to act as a single biological unit for the grounding rail to recognize the signature."

  "She’s... she’s so hot," Era gasped, her head falling back against Xenia’s shoulder.

  "And she’s freezing," Xenia growled, though her voice cked its usual bite. Her amber eyes were clouded with a sudden, intense surge of shared energy. "Kaito... do it. Before I bite her."

  Kaito didn't hesitate. He fastened a single, extra-wide leather strap across both of their waists, pinning them together. He then reached down, his hands sliding over their intertwined legs to ensure the femoral leads were connected.

  "Tandem Cycle: Initiated," Kaito said. He pulled the lever.

  The workshop didn't roar this time; it moaned. The violet and orange lights of the crystal fused into a violent, pulsing magenta.

  The feedback was instantaneous. Because their nervous systems were linked by the conductive gel, the relief wasn't just physical—it was empathetic. Era felt Xenia’s raw, predatory hunger for combat; Xenia felt Era’s cold, sharp terror of failure. The two sensations collided in the center of the chair, creating a localized mana-storm that whipped Kaito’s hair back.

  Kaito didn't watch with the eyes of a lover; he watched with the eyes of a technician monitoring a high-risk pressure test. To him, the sound of Era’s melodic cries blending with Xenia’s guttural roars was merely acoustic data indicating the desaturation of their core vessels. He moved around the chair with mechanical precision, his hands reaching into the tangle of slick, heaving limbs to adjust silver-wire leads that were vibrating loose.

  He reached down, applying a secondary yer of gel to the underside of Xenia's thighs where the friction was creating a thermal bottleneck. Xenia arched her back, her cws digging into the leather armrests as she ground her hips against the back of Era's seat, the shared current surging between them.

  "Flow rate is hitting 150% of rated capacity," Kaito shouted over the hum of the machine. "Magistrate, visualize the intake! Xenia, stop fighting the draw and vent!"

  As the session reached its zenith, the air in the workshop became heavy with the combined musk of the two women—a floral, ozone-heavy scent that Kaito noted would require a more robust ventition system in the next upgrade.

  Era’s body went completely limp against Xenia, her eyes rolled back in a state of total system-flush. Xenia followed a second ter, a massive, shuddering release that caused the brass valves on the chair to hiss with steam.

  [Tandem Calibration: 100% Complete]

  [Data Points: +350]

  [System Notification: Harem Resonance Unlocked - Tier 1]

  The machine died down to a gentle purr. The magenta light faded. Kaito stood back, checking his thermal scanner. Both women were at optimal temperatures, though their heart rates remained elevated.

  "Efficiency rating: 142%," Kaito noted, wiping a bead of condensation from his gsses. "The tandem method is statistically superior to individual sessions. However, the structural wear on the leather is significant. I will need to reinforce the bolting for the next cycle."

  Era remained draped over Xenia’s p, her silver hair tangled with the Hobgoblin’s dark tresses. She didn't look like a Magistrate; she looked like a woman who had just had her soul scrubbed clean. Xenia’s arms were still around her, her chin resting on the Elf’s head in a protective, dazed fog.

  "I... I can't move," Era whispered.

  "Good," Xenia panted, a slow smirk tugging at her lips. "I was getting tired of you pacing anyway."

  Kaito ignored the budding intimacy. He was already at his desk, his pen flying across his ledger.

  "The mandate, Magistrate," Kaito said, tapping his pen against the crate. "I suggest you finish it now. Your cognitive crity is currently at its peak. Xenia, the door still needs a bolt-lock. I expect it installed by sunset. We have five days until Thorne returns, and I refuse to have my production schedule interrupted by a ck of basic security."

  Kaito looked at the 350 Data Points. He had enough to finally unlock the Neural Interface.

  "System," Kaito whispered. "Begin the blueprint assembly. We’re moving to Tier 3."

  He picked up his soldering iron, the blue light of the HUD reflecting in his spectacles.
