At a glance from Soma, Akutsu stepped forward. Blows to the head didn’t seem to be having enough of an effect, so Akutsu went for the stomach instead, driving his fist into the abdomen of the man tied up before him. The man doubled up and wheezed pathetically as Akutsu stepped back, attention snapping to Soma, at the ready in case he would be needed again.
Soma waited a few seconds before he resumed talking, casually brandishing his knife as he questioned the other man. Truthfully, Akutsu couldn’t even remember what the hell they were torturing this guy for. It was hard to pay attention to some nobody punk tied to a chair when Soma was in his element just a short arms-length away.
Soma was still talking, but Akutsu didn’t hear the words so much as he heard the tone, smooth and even like a fine whiskey, or the rush of blood from a fresh laceration. Soma’s long fingers twirled his knife about effortlessly, a casual flick of his wrist sending its sharp point whipping past their victim’s face, missing it by mere centimeters. His expression remained impassive while he listened to the other man babble a response to something, but there was a faint gleam to his eye. He was enjoying himself. Akutsu swallowed and shifted his weight.
After a few more exchanges, Soma sighed softly. The casual deftness with which he spun his knife morphed into something more deliberate and threatening. He must’ve learned all he could from the man, and was now getting ready to end the session. Akutsu took a step back to give himself a better view as Soma placed a hand on the back of the chair and moved behind their victim.
Light flashed across the silver blade as Soma brought it up to their victim’s neck. Soma’s gaze slid to Akutsu, and then his arm jerked, swift and sudden. The thin skin of the other man’s throat spread open, blood pouring in streams down his neck as he choked and sputtered, jerking instinctively against his restraints. The knife was spotless. Soma’s face was cold indifference.
Akutsu was hard and throbbing. He twitched in his pants as Soma slid the knife back in his pocket and said, “With me, Akutsu. The rest of you, clean this up.”
They left to a chorus of “yes, boss.” Akutsu dutifully trailed Soma back to his office, hunching a bit as he walked to aid his baggy sweatpants in hiding his erection. That wasn’t something he needed the others talking about.
Akutsu closed the door and locked it behind him. He stood and watched as Soma walked over to his desk and dropped his knife into a beaker, swirling it around in the cleaning fluid within. “You did well today, Akutsu,” Soma said. “You’re getting better at reading people and adapting your tactics.”
“Uh, thanks.” The praise swept through Akutsu in a warm rush that went straight south. Soma didn’t offer him compliments often, so he must be genuinely pleased.
“You’ve been performing all your duties well lately,” Soma continued as he pulled the knife out and wiped it off with a handkerchief. “I do appreciate it. And I would reward you, if you’ll accept it.”
“Yeah,” Akutsu replied, much too quickly. He cleared his throat. “Yeah,” he said again.
“Excellent.” A faint smile flitted over Soma’s face. He tucked the handkerchief away and beckoned with the knife. “Come here.”
Akutsu moved closer, until he was standing by the desk and looking down at Soma.
“Remove your shirt,” Soma ordered.
Akutsu pulled his shirt over his head and dropped it to the floor. Goosebumps prickled over his skin in the cool air.
“Good,” Soma said softly. His eyes ran over Akutsu’s bare torso appraisingly. He followed his eyes with his hand, so the point of the knife hovered just above Akutsu’s skin. He stopped at Akutsu’s throat and held the knife point there for a few seconds before carefully pressing the tip into the skin. Akutsu swallowed to feel the sting of it as it dug in a little deeper.
Soma’s eyes flicked up to Akutsu’s as he pressed the point in further, until a little pinprick of blood welled up under it. He held his gaze as he shifted to press the flat of the blade hard against Akutsu’s throat and then dragged it to the side, in a slow approximation of what he’d done to their torture victim earlier. His grip shifted again as he dragged the flat edge down Akutsu’s neck, pressing in just enough that Akutsu could feel the point grazing his skin. Akutsu swallowed again and closed his eyes with a sharp inhale as the movement pressed the knife deeper.
Soma continued down Akutsu’s neck and moved over to his tattoo, tracing its lines down his shoulder and to his chest. He paused at a nipple and tapped his blade against the silver barbell running through it. “This is new,” he commented.
“Yeah-” Akutsu agreed, cutting himself off with a groan as Soma scraped the flat of his blade over the nipple, hard. “Just bought ‘em a few days ago,” he finished with a gasp. Soma merely hummed and scraped back over the nipple, slow and rough. The barbell caught against the blade and tugged the nipple up with it, sending a sharp jolt of pleasure down to Akutsu’s cock. He was starting to leak precum against his underwear, and he shifted his stance so the wet spot wouldn’t cling to him.
Soma toyed with his chest for a while longer before trailing the knife down his pec and towards his ribcage. When he reached Akutsu’s heart, he deftly flipped the knife so that the sharp blade dug into the skin, parting it so cleanly it took Akutsu a second to realize it was even happening. Akutsu hissed as warm blood flowed to the surface and started to trickle down his abdomen.
Soma’s knife continued its stinging trail down Akutsu’s stomach until it reached the waistband of his pants. It stopped briefly, and then Soma pushed the tip into the soft flesh until it was seated firmly inside Akutsu. “Would you like a new scar?” Soma asked.
“Yes,” Akutsu’s answer came immediately. He shifted again, relishing the small jolt of pain as he felt the knife tip move inside him. His underwear was a lost cause at this point, as the blood started to seep into it while his cock twitched and spurted more precum.
Soma’s voice was a low murmur as he looked up at Akutsu. “What should I write for you?”
“RK.” Soma would like that, Akutsu thought.
The small smile Soma gave him told him he was right. “Very well,” Soma said. He pulled the knife back and gripped Akutsu by the hips to turn him into the light. His thumb swept over the spot above Akutsu’s hips where the characters for Soma’s given name stood raised in clean white lines, the very first scar Akutsu had ever asked him for. He moved his thumb lower, just below it. “Here,” Soma decided, raising his knife once more.
Akutsu gasped as the knife sunk into his flesh, far deeper than before, dragging straight down in a burning line of pain. And then again, curving and looping this time, slow and steady as Soma connected the lines. Three more lines as Akutsu groaned and gritted his teeth, blood pouring down his hip and soaking into his pants. Spots swam behind his eyes as he fought to keep his knees from buckling beneath him.
Soma carefully withdrew the knife, the formerly pristine silver now dripping with thick globs of red blood. Akutsu immediately twisted to brace a hand against the desk, his breathing ragged.
“Good,” Soma said as he eyed his handiwork critically. “It turned out well.”
“Great,” Akutsu gasped. “Thanks.” His pants and underwear both were clinging to him, wet and warm, and they rubbed against his still hard cock as his legs shook.
Soma pointed the knife upwards, so that the blood slowly dripped down the blade onto the handle and over Soma’s fingers. “Pants off,” he ordered.
Arousal that had nothing to do with his fresh wounds swept through Akutsu. Soma never dirtied himself with the bodily fluids of others while working, but now Akutsu’s blood trickled down his hand, threatening to run down his wrist and soak into his undershirt. Akutsu’s hands shook as he peeled off both his pants and underwear.
The reddened knife pressed into his hip and glided down the crease of his inner thigh, leaving a shallow cut in its wake. Soma flipped the knife again and scraped the flat edge against the base of his cock and up to the head, gently teasing the slit with the knife’s point. Akutsu moaned and fought to keep his hips still as his cock spurted more precum onto the blade.
Soma scraped the knife over the head again, then trailed it down and pushed it into the sensitive spot under the head. Akutsu moaned again, the wood of the desk creaking under his hands as he fought to stay standing. The knife kept moving, down the underside of his cock and to the soft skin of his balls, where the tip lightly traced in circles.
“Brace against the desk and spread your legs,” Soma said, pulling back.
Akutsu gratefully turned into the desk and braced his other hand against it, spreading his shaky legs as much as he could manage without collapsing. The spots behind his eyes grew larger and darker with the movement, his head fuzzy with dizzying arousal.
Soma trailed a wet finger down his backside and to his ass. He circled the rim of Akutsu’s hole briefly before pushing straight in. Akutsu inhaled sharply at the sensation and struggled to relax his tense muscles. Soma’s finger was still dripping blood, wet enough to ease the entry but not to soothe the friction burn.
Soma added another finger and twisted them to rub against Akutsu’s prostate. “You’ve bled so much I hardly think we’ll need lube,” he commented, and Akutsu bit back a groan as his dick twitched and he clenched around Soma. Soma withdrew his fingers and held the wet hilt of the knife in front of Akutsu. “Good enough for you?” he asked.
The hilt was smeared over with Akutsu’s blood, still glistening in the light and leaving red smudges where it lay against Soma’s hand. Akutsu nodded, groaning as the movement made his vision temporarily black out. “Yeah, ‘sfine,” he slurred.
Soma snatched the knife back and withdrew his handkerchief from his pocket. He wrapped the blade in the thick fabric and then gripped it tightly in his hand, testing to make sure the fabric would hold. Satisfied, he shifted to stand behind Akutsu, and Akutsu dropped his head down to stare at the polished wood of Soma’s desk.
A hand trailed lightly down Akutsu’s spine, and then the hilt of the knife unceremoniously shoved inside him. Akutsu’s eyes widened at the burn of the stretch, the wood of the desk creaking dangerously as he tightened his grip. “Relax,” Soma murmured. The knife slowly pushed deeper, until the hilt was fully seated inside him, hard and unyielding. It shifted as Soma adjusted the angle, and then it rubbed lightly against his prostate.
Sparks of pleasure burst among the spots in his eyes as his muscles gradually relaxed around the intrusion. Soma slowly dragged the hilt back out and then shoved it in again, brushing against Akutsu’s prostate. He built up a slow, hard rhythm, and Akutsu closed his eyes and leaned harder against the desk as his legs shook and his head swam with pleasure. His cock continued to leak precum steadily, twitching in interest as warm blood from the cut on his thigh dribbled over the base.
Soma shifted the knife again, and on the next thrust it drove directly into Akutsu’s prostate. Akutsu’s eyes flew open as his back arched, clenching around the knife’s hilt hard. “Careful,” Soma cautioned, voice laden with amusement. “Suck it in much farther and you’ll do some real damage.”
Akutsu only clenched harder at the words, drawing it in that much deeper. His cock ached as his balls tensed up warningly. “Soma,” he gasped, desperately seeking permission.
“Not yet,” Soma chided, thrusting in with the knife again. Akutsu groaned and fought to push back his orgasm, focusing on the ache in his arms and legs instead.
Soma toyed with him for what felt like hours, driving the hilt into his prostate again and again as Akutsu’s head grew fuzzier and his legs grew weaker. The blood from his fresh scars had run down the length of his leg and now pooled around his foot on the floor. His arms had started to shake, straining from having to support so much of his weight. He groaned weakly as Soma rubbed a hand against his spine again.
“Hm,” Soma said, driving the knife in hard. “You may come now.”
Akutsu gasped in relief as his body obeyed immediately. Pleasure washed over him, all his muscles tensing up as he shot thick ropes of cum onto Soma’s desk. He slumped as it faded, locking his arms to keep himself from falling. His vision was slow to return, the whole world growing dark and hazy as he panted and struggled to collect himself.
Soma slowly eased the knife out and dropped it hilt-first into the beaker. He wiped his bloody hand with the shredded handkerchief before dropping it to the desk. His hand rubbed at Akutsu’s back once again, and then he guided Akutsu to sit in a nearby chair. Akutsu collapsed gratefully, eyes fluttering shut.
“Do you think you can treat it yourself?” Soma asked softly. Akutsu was slow to respond, and Soma moved away automatically, fetching a gauze pad from his desk and kneeling before Akutsu to press it into his fresh wound. Soma cleaned the wound and stayed with him for a while as Akutsu slowly came back into himself, his vision clearing and some of the fuzz in his head receding.
After Akutsu was able to sit up, Soma moved away again and came back with a can of sugary soda. “Drink,” he commanded. “All of it. When you feel a bit better, you may dress and leave. I’ll handle cleanup this time. Make sure to eat something sweet after you leave, as well.”
“Yeah, yeah, I know the drill,” Akutsu told him, cracking open the can and taking a long sip. He nursed the drink a bit longer than necessary, just to watch Soma wiping up his blood and cum. Usually Akutsu had to clean. It was nice to be able to sit and relax.
Eventually Akutsu ran out of reasons to linger, and he dressed himself in his blood-drenched clothing and slunk out of Soma’s office, keeping his head down as he went straight for the exit.
After his bath that night, he stood in front of the mirror and admired the neat penmanship of his new scar, lightly tracing his fingers over it again and again until it swelled and stung.
