The cold steel of the restraints bit into Nathan's wrists as he stood in the dimly lit laboratory, his breath coming in shallow gasps. The room was filled with the hum of machinery and the faint whirring of robotic components, a testament to Lei's genius. But Nathan wasn't here for the inventions; he was here for something far more personal, and far more dangerous.

Lei, the brilliant inventor, stood before him, his eyes glinting with a mix of amusement and dominance. His tall frame loomed over Nathan, who was dressed in nothing but a thin robe that barely concealed his muscular body. Lei's fingers traced the outline of Nathan's chest, sending shivers down his spine.

"You know why you're here, don't you?" Lei's voice was low and commanding, a stark contrast to the gentle touch of his hand.

Nathan nodded, his throat dry. "Yes, sir."

Lei's lips curled into a predatory smile. "Good. Because I don't tolerate disobedience."

With a swift motion, Lei yanked the robe off Nathan's shoulders, letting it fall to the floor in a heap. Nathan's skin prickled under the cool air, but it was Lei's gaze that made him feel truly exposed. The inventor's eyes roamed over his body, taking in every inch with a possessive hunger.

"On your knees," Lei ordered, his tone leaving no room for argument.

Nathan hesitated for a moment, his pride warring with his need to comply. But the look in Lei's eyes told him that defiance would only lead to pain. Slowly, he sank to his knees, his hands still bound behind his back.

Lei crouched down in front of him, his face inches from Nathan's. "You're going to be a good boy for me, aren't you?"

Nathan swallowed hard, his heart pounding in his chest. "Yes, sir."

Lei's hand moved to the back of Nathan's head, fingers tangling in his hair. With a sharp tug, he forced Nathan's face closer to his own. "Open your mouth."

Nathan obeyed, parting his lips just as Lei's other hand reached between his legs. The inventor's fingers wrapped around Nathan's cock, stroking him with deliberate slowness. Nathan's breath hitched, his body responding instinctively to the touch.

"Such a slut," Lei murmured, his voice dripping with disdain. "You can't even help yourself, can you?"

Nathan could only shake his head, his mind clouded with arousal and fear. Lei's grip tightened, his thumb pressing against the sensitive tip of Nathan's erection.

"Beg for it," Lei demanded, his eyes boring into Nathan's.

Nathan's voice was barely a whisper. "Please...sir...I need it..."

Lei chuckled, the sound dark and menacing. "Need what, exactly?"

"Your...your cock," Nathan stammered, his cheeks flushing with shame.

Lei released his hold on Nathan's hair, standing up and stepping back. "Strip."

Nathan's hands were still bound, but he managed to shimmy out of his pants, leaving him completely naked and vulnerable. Lei watched with a satisfied smirk, his eyes never leaving Nathan's body.

"Now, get on the table," Lei commanded, pointing to a sleek, metal examination table in the center of the room.

Nathan climbed onto the table, lying down and spreading his legs wide. Lei approached, his eyes gleaming with anticipation. He reached into a nearby drawer and pulled out a bottle of lube, setting it on the table within reach.

"Get ready," Lei said, his voice a low growl.

Nathan's heart raced as he reached for the lube, squeezing a generous amount onto his fingers. He knew what was coming, and the thought both terrified and excited him. He worked the slick substance into his hole, preparing himself for Lei's invasion.

Lei watched with rapt attention, his breathing heavy. When Nathan was sufficiently lubed, Lei stepped forward, positioning himself between Nathan's spread legs. He didn't waste any time, lining his cock up with Nathan's entrance and pushing inside in one swift motion.

Nathan gasped, his body clenching around Lei's thick shaft. Lei paused, giving Nathan a moment to adjust, but his expression was anything but patient. His eyes locked onto Nathan's, daring him to protest.

But Nathan had no intention of resisting. Instead, he arched his back, pushing himself further onto Lei's cock. Lei let out a low groan, his hips snapping forward as he began to thrust.

"Fuck, you're tight," Lei muttered, his hands gripping Nathan's thighs hard enough to leave bruises.

Nathan whimpered, his body trembling with each brutal thrust. Lei's pace was relentless, his strokes deep and punishing. Nathan could feel every inch of him, the sensation overwhelming and intoxicating.

"Look at you," Lei sneered, his voice dripping with contempt. "Taking it like a whore."

Nathan's eyes fluttered closed, his mind reeling from the intensity of the experience. He could feel himself getting close, his body betraying him as it responded to Lei's rough treatment.

"Don't you dare come," Lei growled, his fingers digging into Nathan's flesh. "Not until I say so."

Nathan bit his lip, struggling to hold back his orgasm. Lei's thrusts grew even harder, his cock slamming into Nathan with brutal force. Nathan's entire body shook, his muscles straining as he fought to obey.

"That's it," Lei purred, his voice a harsh whisper. "Take it all, you dirty little slut."

Nathan's vision blurred with tears, his body pushed to its limits. He could feel Lei's cock pulsing inside him, the inventor's control slipping as he neared his own climax.

"Please," Nathan begged, his voice breaking. "Please, sir..."

Lei's response was a guttural roar as he came, his seed filling Nathan's ass with hot, sticky spurts. Nathan cried out, his own release finally breaking free as he spilled over the edge, his body shuddering with the force of his orgasm.

Lei collapsed on top of him, their bodies slick with sweat and cum. For a moment, there was only the sound of their ragged breathing, the world outside the lab forgotten.

Then, Lei lifted his head, his eyes dark and unreadable. "Get up," he ordered, his voice cold and detached.

Nathan struggled to obey, his limbs trembling with exhaustion. He slid off the table, landing on shaky legs. Lei watched him with a calculating gaze, his expression unyielding.

"Clean yourself up," Lei said, turning away. "And remember, this is just the beginning."

Nathan nodded, too drained to speak. He stumbled to the bathroom, his mind racing with thoughts of what lay ahead. Lei's words echoed in his ears, a chilling reminder of the power dynamics at play.

As he cleaned himself, Nathan couldn't help but wonder what else Lei had in store for him. And despite the fear gnawing at his insides, a part of him couldn't wait to find out.

“Strip,” Lei interrupted, his voice cutting like a blade. “Or I’ll have you replaced.”

The threat was enough to make Nathan comply, though his hands trembled slightly as he unbuttoned his shirt and let it fall to the floor. Lei stepped closer, his fingers brushing over his chest, and Nathan froze, his breath catching in his throat.

“Such a strong body,” Lei murmured, his tone almost reverent. “It’s a shame to keep it hidden.”

Before Nathan could respond, Lei had pulled out the maid uniform—a ridiculous, frilly thing—and held it up with a wicked grin.

“Put it on.”

Now, kneeling on the floor, Nathan’s cheeks burned with humiliation. The uniform clung to him in all the wrong places, the lace scratching against his skin and the apron fluttering with every shaky breath he took. Lei circled him like a predator, his shoes thudding against the floor.

“You look… adorable,” Lei teased, his tone mocking. “Such a pretty little maid.”

Nathan’s fists clenched, but he stayed silent. Lei stopped behind him, his hands resting on his broad shoulders.

“Stand,” he ordered.

Nathan obeyed, his towering frame dwarfing Lei’s. But despite the size difference, Lei’s presence was commanding, his confidence unshakable. He stepped closer, his fingers trailing down Nathan’s chest until they reached the hem of the apron.

“You’ve been such a good boy,” Lei purred, his voice dripping with condescension. “You deserve a reward.”

Before Nathan could react, Lei’s hand came down hard on his ass, the sharp smack echoing in the room. Nathan’s breath hitched, a mix of pain and something else—something he didn’t want to acknowledge—surging through him.

“Again,” Lei demanded, his voice firm.

The second slap was harder, and Nathan’s knees buckled slightly. Lei chuckled, his fingers digging into his hips to steady him.

“Sensitive, are we?” he teased.

Nathan’s face burned, but he couldn’t deny the heat pooling in his gut—the shame, the arousal, the way Lei’s touch sent fire through his veins.

Lei stepped around to face him, his hand sliding up to cup his cheek. His touch was unexpectedly gentle, his thumb brushing away a tear that had slipped free despite Nathan’s efforts.

“You’re mine,” Lei whispered, his voice soft but laced with steel. “And I’ll do whatever I want with you.”

Nathan’s breath hitched, his mind racing as Lei leaned in, his lips brushing against his ear.

“Now,” he murmured, his voice a low purr, “over the desk.”

“Sir..”

“Now.”

Nathan hesitated for only a moment before obeying, his hands trembling as he bent over the polished surface. Lei’s hand trailed down his back, his touch sending shivers through him.

“Good boy,” Lei murmured, his voice filled with dark promise. “Let’s see how much more you can take.”
