Naruto: The Shameless Uchiha Tycoon

Three weeks had passed since the first disastrous factory inspection.

Inside Ren’s commercial-district office, Kakuzu placed a locked luxury case onto the center of the heavy desk. The reports beside the case confirmed that the revised batch was safe, quiet, durable, and far less likely to require Kakuzu’s kunai.

Ren unlocked the latches and opened the lid.

Inside were the products that still required practical testing: a simple mass-produced vibrator, a quieter luxury model with a detached control, padded restraints, one lingerie set, cleaning supplies, and the first rough feedback harness.

Ren picked up the padded restraints and fastened them around a heavy wooden paperweight on his desk. He tested the normal latch. It opened smoothly. He locked it again and pressed the marked emergency stud. The stored seal discharged, and the cuffs snapped open immediately without requiring him to channel chakra.

Kakuzu, standing a few feet away, still kept a drawn kunai near his side until the cuffs fell completely open.

Ren looked at him. "Are you planning to remain for the practical testing?"

Kakuzu sheathed his weapon, closed the factory report, and stepped back. "I expect a written list of faults on my desk by morning."

He turned and left the office before Ren could even tell him who the tester was going to be.

Early that evening, Ren carried the locked case across the courtyard to Kushina’s house.

He found her sitting at the low table, feeding Naruto a bowl of mashed vegetables while actively trying to stop the boy from destroying a folded business report she had borrowed from Ren’s office.

Ren reached over and rescued the crumpled parchment.

Naruto immediately abandoned the report and reached his chubby hands toward the polished, expensive-looking case Ren had just set down. Kushina grabbed the handle and moved the case onto a high shelf well out of his reach.

Once Naruto finally finished eating and the bowls were cleared, Kushina brought the case back to the table and opened it.

She recognized the basic purpose of most of the products immediately, but she still laughed at the sheer amount of effort Ren had put into the packaging, the detached controls, the adjustable straps, the cleaning supplies, and the detailed instruction cards.

"You have been selected as the first private tester," Ren told her.

Kushina did not act shy. She crossed her arms and immediately negotiated her fee.

"I demand dinner during your next capital trip," Kushina listed. "A full bottle of my preferred perfume. The first completed luxury set. The absolute right to stop any test without argument. And the right to call a product completely useless, even if Kakuzu likes the profit margin."

Ren accepted the terms easily.

Kushina looked at the open case. "Does this make me an employee?"

"Kakuzu would demand a written contract before paying you," Ren pointed out.

"Then the perfume and dinner are safer."

Any immediate testing became impossible because Naruto remained wide awake and highly energetic.

Ren carried him around the room while Kushina prepared their own dinner. Naruto entertained himself by pulling Ren’s hair, attempting to steal his spoon, and staring in deep fascination at the shiny brass latches on the locked prototype case.

"You should create a product capable of restraining troublesome red-haired children," Kushina joked, setting plates on the table.

"Using adult restraints for childcare would destroy the company before the public launch," Ren noted, shifting Naruto to his other hip.

After dinner, Naruto absolutely refused to sleep. Ren and Kushina spent nearly an hour changing him, carrying him in circles around the room, repeatedly returning a wooden toy he kept throwing out of the crib, settling him back into bed, and waiting in the dim light until his breathing finally leveled out.

Kushina stood near the doorframe and activated the simple alarm seal. It would pulse immediately if he woke up or tried to climb out.

Only once Naruto was sleeping safely in his separate room did Kushina pick up the case and carry it down the hall to her bedroom.

Ren sat near the foot of the large bed, the open case resting beside him on the mattress. He wore his ordinary dark shirt, trousers, and house sandals.

Kushina closed the bedroom door. She looked at him, then at the assorted toys, straps, and bottles. "Are you going to explain every mechanism, or are we actually going to test something?"

"The lingerie first," Ren said. "The fit can be evaluated without activating any seals."

Kushina unfastened her loose red house dress, letting it fall to the floor, and stepped out of her simple underwear. She picked up the folded prototype set and pulled it on.

Black sheer fabric hugged her body, with narrow straps curving over her hips. Short garters held up the dark stockings, while the open cups pushed her breasts upward and left her nipples bare. The thin lower piece barely concealed her natural red hair.

It looked attractive, but the practical fit was flawed.

One of the breast straps twisted awkwardly beneath the heavy weight of her chest. Kushina reached around her back, struggling to reach the complex clasp without assistance, and when she raised one leg to rest her knee on the bed, the lower hip straps shifted completely out of place.

Ren stood up and stepped behind her, securing the back clasp. His hands moved smoothly around her ribs, slipping beneath the twisted breast straps to locate exactly where the thin material rubbed against her skin.

He cupped her breasts through the open lingerie, his thumbs brushing over her bare nipples.

Kushina watched him through the dressing mirror. "You are supposed to be inspecting the stitching."

"The garment must also remain comfortable while the customer is distracted," Ren claimed, leaning down to press a kiss to her neck.

Kushina turned in his arms and kissed him deeply. Ren’s hands remained on her breasts, squeezing the exposed flesh while her breathing grew heavier against his mouth.

Ren laid Kushina back against the bed and tested the basic model first, running it along her inner thigh before settling it against the outside of her pussy. It was smooth and quiet, but the lowest setting barely drew a reaction while the second made her hips jerk sharply. Kushina approved the product itself and rejected the massive gap between the first two levels.

Ren set it aside and took out the quieter luxury version.

Ren settled between her legs. He held the luxury vibrator firmly against her wet, swollen clitoris and handed the detached control to Kushina, instructing her to operate it without looking.

Two of the buttons were positioned too close together.

Kushina blindly pressed the wrong button, jumping several settings at once. Her hips jerked off the mattress, and a broken laugh escaped as her fingers tightened around the control.

Instead of lowering it immediately, she gripped the sheets and endured the stronger vibration. "Real customers will absolutely make that same mistake."

She deliberately tested several higher settings, her hips bucking upward while Ren held the device firmly in place. The highest output was intensely powerful, causing Kushina to gasp sharply and squeeze her thighs against his forearms.

Ren took the control from her long enough to feel the nearly identical buttons beneath his thumb. Kushina was right. In the dark, there was no reliable way to tell them apart, and the highest setting was far too easy to activate accidentally.

Kushina looked toward the open case, her chest heaving. "Are those the cuffs Kakuzu attacked with a kunai?"

Ren demonstrated the normal latch and the emergency release. "Do you agree to test them?"

"Yes."

Ren fastened the padded restraints securely around her wrists and anchored the straps to the heavy wooden headboard. Kushina pulled against them firmly. The leather pulled taut, but the thick padding remained perfectly comfortable and the straps held without tightening or cutting into her skin.

Ren picked up the luxury vibrator again. With her hands restrained, he dragged the vibrating toy over her thighs before settling it firmly against her clitoris, his free hand moving heavily over her exposed breasts and pinching her bare nipples.

With the blindfold covering her eyes, Kushina could no longer anticipate when Ren would move the toy or change the setting. Her moan rose sharply when he returned it to her clitoris, and she pulled hard against the padded cuffs.

When the tension spiked too high, Kushina arched her back. "Release."

Ren set the vibrator aside and struck both emergency studs with his thumbs. The stored seals discharged, and the cuffs opened at once.

Kushina pulled her arms down, removed the blindfold, and rubbed her wrists. The padding had left faint pressure marks, but nothing painful.

"Kakuzu will be disappointed no kunai was needed," she joked, still flushed and breathing hard.

Kushina sat up, her eyes landing on the largest compartment of the luxury case.

Ren removed the first working feedback harness. Compared with the polished vibrators, it was plainly unfinished: black waist and thigh straps, one smooth attachment, protected seal markings, an emergency-release tab, and a feedback dial near the hip.

"The seals transfer whatever happens to the attachment back to the woman wearing it," Ren explained.

Kushina looked between him and the harness. "So she can feel it while using it on another woman?"

"That is the idea."

"Whoever originally designed this was an extremely dedicated pervert."

She stepped into the thigh loops while Ren tightened the straps around her hips. One sat slightly lower than the other, and the dial was awkward to reach, but the harness remained secure while she stood still.

Ren tested the emergency release three times before fastening it again.

"Try it."

Kushina wrapped her fingers around the attachment and gave it one slow stroke.

An unfamiliar pressure moved between her thighs.

She froze, staring down at her hand.

Kushina stroked it again, moving slowly from the rounded head toward the base. A soft moan slipped from her lips, and her hips shifted forward on instinct.

"It really works."

Her hand moved again. Each stroke returned through the seals, the strange sensation becoming clearer as her grip tightened.

She twisted awkwardly, managed to turn the dial one level higher, and gasped.

Ren opened the lubricant and spread a little over the attachment. Kushina tested it with another stroke. The formula remained slick beneath her palm and warmed slightly as her hand began moving faster.

Her breathing grew ragged.

One hand caught Ren’s shoulder while the other worked rapidly along the smooth length. Her thighs trembled beneath the harness, and her hips began rolling forward in time with every stroke.

"Is... is this how men feel?"

Ren opened his mouth, but Kushina was already too lost in the unfamiliar feedback to wait for an answer.

Her fingers tightened near the head before dragging down again. The pressure struck sharply between her thighs, tearing a broken cry from her.

"Ren... I’m—"

Kushina’s body locked. Her thighs shook, and wetness spilled down between them as the stimulation pushed her over the edge. Her fist continued moving through the first sharp contractions before her rhythm broke and her hand finally stopped near the base.

She leaned against Ren for several seconds, breathing hard.

Then she looked down at the harness.

"I want this."

Ren raised an eyebrow. "Why?"

The secretive smile spreading across her flushed face immediately made him suspicious.

"You don’t need to know."

She rolled her hips experimentally.

The left thigh strap slipped downward at once, pulling the attachment crooked and ruining her satisfaction.

Kushina stared at the loose strap with open betrayal.

Ren switched off the seal and began undoing the buckles. "This one is going back to the factory."

"Then I want the first corrected one."

"The first finished harness is for the capital demonstration."

Kushina gave him a flat look.

"The second one," Ren amended.

"Acceptable."

Ren removed the harness, tossed it beside the case, and looked back at the still-flushed Kushina.

"I am finished testing your products for the night."

She grabbed the collar of his dark shirt, dragged him fully onto the bed, and kissed him hard enough to stop whatever explanation he had been about to give.

Ren quickly stripped off his shirt and trousers. Kushina kept the flawed lingerie and stockings on, genuinely liking how they looked despite the twisted straps.

Ren opened the bedside drawer and took out one of the contraceptive seals he and Kushina had begun keeping there after their earlier scare. He pressed it below his navel and waited for the mark to warm.

She pushed him onto his back and climbed on top, guiding his hard cock into her slick pussy. She sank down with a long groan, taking him fully. Her hips began moving in a steady rhythm as she picked up the luxury vibrator and set it to the level she had preferred earlier.

Ren’s hands gripped her hips, anchoring her as she rode him. The wet, slapping sound of their bodies filled the bedroom.

A few minutes later, Ren gripped her waist tightly, rolled them over, and pinned her beneath him. He gripped beneath her thighs, spread them wider, and drove into her with a faster, deeper rhythm. Kushina wrapped her legs around his waist, keeping the luxury toy pressed against her clitoris while his thrusts drove her deeper into the mattress.

Kushina’s climax hit first, her inner walls clenching violently around his cock. Ren drove into her through the contractions until his own release hit, burying himself deep and coming inside her.

Ren switched the vibrating device off, withdrew slowly, and helped Kushina unfasten the tangled, flawed lingerie.

Only after they had cleaned themselves and wiped down the used products did Ren pull a notebook from the case to write the report.

Kushina lay back against the pillows, covered by a sheet, and delivered her corrections bluntly.

"The top needs to hold my breasts without trying to strangle my ribs," Kushina said, "and I should not need a second person merely to close it. The hip straps kept moving every time I lifted my leg."

She pointed toward the two vibrators.

"The cheaper one is fine once you smooth out the first two settings. The expensive control needs buttons I can actually tell apart in the dark, and nobody should reach the strongest setting by accident."

Finally, she lifted the harness by its loose strap.

"This part feels incredible. Everything meant to keep it on me is useless."

Ren translated her blunt complaints into language the factory managers could use. The restraints were approved. The lubricant remained smooth during use, and the cleaning supplies removed every trace from the products without damaging their surfaces.

Ren closed the notebook and pushed the approved luxury vibrator, restraints, lubricant, and cleaning kit toward her.

"Those are yours. The harness goes back to the factory."

Kushina gathered the approved products without argument, but her eyes remained fixed on the harness.

"I still want the second corrected one."

"You already negotiated that."

"I am making sure you remember."

"The noblewomen in the capital are already waiting for the collection," Ren said as he finished the report.

Kushina glanced toward the feedback harness.

"Your noble clients are going to fight over this."

The alarm seal on Naruto’s doorframe gave a soft, sudden pulse.

Kushina immediately sat up, pulled her red house dress over her head, and left the bedroom to check on her son.

Before she stepped out of the room, she pointed back toward the harness resting beside the case.

"Fix those straps before you take it to that private showing. They will blame you when one of them falls off the bed."

Ren looked down at the prototype and the short correction list.

The basic products were nearly ready for mass production. The luxury set needed only a few adjustments.

The feedback harness worked—but its straps and support had to be rebuilt before Ren placed it in the hands of his most influential clients.
