Manipulation through sex is a common form of puppeteering with a fairly low required skill set, but Izaya isn't one to turn his nose up at something that his humans seem to enjoy with so much fervor. He's not in the habit of denying joy to his body either, be it in the form of delicious sushi on his tongue or a hard cock slamming into his prostate. Using the pleasure to twist his partner's actions and emotions around his little finger is an added bonus to make it all the sweeter.

Izaya loved this game regardless, but it is nice to have such a nicely carved chess piece from time to time, perfectly crafted for its role on his game board.

The man behind him is undeniably attractive. Genetics had blessed him with an aesthetically-pleasing bone structure that he'd had the money and good sense to enhance with expensive grooming habits. The clothes he'd been wearing when Izaya had chosen him for his evening's entertainment had clearly been carefully selected to accentuate without being ostentatious. The muscles that he'd felt beneath those clothes before making his decision promised that he'd have the stamina to keep doing what he was currently doing to Izaya for quite some time.

Of course, Izaya hadn't come here just for the man's body. With an exaggerated moan, Izaya gazed becomingly over one shoulder, dewy eyes set to beguile the prostitute who was hard at work behind him. If he was going to spend his evening at a brothel renowned for its discretion in providing specialty services, he was going to leave with the dirt on at least a few powerful people.

He bit his lip, eyes hopeful. Trained to read such signs, the man gradually slowed his pace (which Izaya did, briefly, regret), and reached a hand out to tuck a strand of Izaya's hair behind his ear.

"What is it, sweetheart?" he asked, only subtlety writhing against him now.

Inwardly, Izaya smirked. Outwardly, he blushed. He softened his voice, just a touch, hesitated. He'd need to draw this out at least a few more minutes for the drug to fully kick in.

"I'm—I'm not sure how to say it," he said as he slid his eyes sideways, shyly.

Sensing the reluctance, the man pulled out his own tricks for working out what a client wanted. He lightly ran his hands through Izaya's hair, cupped his chin, and tilted his head upwards to meet his eyes. As he did so, he reached one hand down to Izaya's cock and rubbed it gently while snapping his hips forward.

"You can tell me anything, anything you want me to do, I'll make it happen. Don't be shy."

Dutifully, Izaya moaned and fluttered his eyes briefly closed before again meeting the man's gaze.

"Oh, well, it's just, I just really like, umm, I'd really like it if you told me things, dirty things. Things you've done before, with-, with-," he hesitated here, emphasizing his feigned reluctance, "with other people."

The man chuckled and stroked Izaya's cheek. Izaya imagined that he was likely rolling his eyes inwardly, but he was doing a good show of reassurance regardless.

"Oh, is that all, darling? I'd be happy to recount some of my adventures for you, if that's what gets you going."

And, of course he would. It was a fairly innocuous and easy request by the usual standards of the place. As long as he didn't reveal any identifying features or names, it was an easy kink to indulge. Of course, that's why Izaya's been sure to slip something into his drink, to loosen his tongue a bit more.

Loosen the man's tongue it did. As he continued to pump artfully into Izaya, teasing pleasure out of him with each thrust, the man spoke continuously. Some of the stories are mundane though Izaya enjoys hearing about his precious humans' indulgences nonetheless. Some are quite scandalous, and some Izaya tucks away for later purposes. A councilman likes to be spanked. A board member of a prominent technology company has a thing for pegging. A married couple, both well-known wealthy investors, like to watch each other with others. Possible exploitations, the lot.

Then the man says a name that Izaya was not expecting to hear.

The man tells him that a certain Heiwajima insists on being bound in specially-ordered chains and cuffs to restrain his unnatural strength, and Izaya starts having ideas.

He tells him that Heiwajima insists on being blindfolded and gagged to give over as much power as he can to his anonymous partner, and Izaya starts seeing images.

He tells him that Heiwajima blushes beautifully as he's brought carefully to orgasm, and Izaya starts making plans.

He orgasms, too, of course; he'd gotten everything he'd come for.

Three weeks later, Izaya was back at the brothel, waiting outside of a room not terribly unlike the one he'd found himself in before though there was no telling what was behind the door.

Given his contact's descriptions, he assumed that he would find Shizu-chan in some sort of industrial bondage dungeon with heavy, reinforced doors, stark walls, and all metal furnishings.

He can see himself having to scrape his knees against a concrete floor as he rides the beast, and he's hoping that he'll get to see him thrash against the cold floor trying to escape to kill him once he rips off the bound monster's blindfold and reveals exactly who has just brought him to his lonely orgasm. He wants there to be a single light bulb that he can shut it off to leave Shizu-chan alone in the dark. He wants to see the strip of light from the door narrow over his face as he closes him in.

Izaya opened the door, unable to resist finding his prize. Quite contrary to his expectations, the room he stepped into seemed like any other boudoir one might find in an upscale brothel. It's moderately sized, luxuriously adorned, softly lit by an array of lamps, and mostly occupied by a large canopy bed.

The curtains around it aren't the thin, fluttery type, but heavy, dark, and undoubtedly saturated with the smoke of incense. They completely obscure the occupant who Izaya knows must be trussed tightly inside, which somehow makes it even more exciting, makes Izaya's mind need to know in what state he might find his monster in this unexpected location.

Reaching out to pull a curtain aside made him feel as giddy as a child with presents.

There's a single sconce lit above the bed, bathing the tableau in flickering light. More light spilled in from behind Izaya, but it was only enough tease the image with more shadows and light.

Shizuo was spread out on the bed, and somehow, even though he was expecting it, knew it, and is only here because of it, Izaya still found himself struggling to comprehend it.

Given his position, Shizuo's hands were clearly cuffed and secured somewhere above his head, but Izaya could only see the thick bands that bound his wrists and a link or two of the chain that held them in place before it disappeared behind the headboard to attach to the wall. Shizuo's arms were supported on an impressive pile of pillows, making it impossible to see anymore.

The specially-ordered chains that Izaya had heard so much about were cunningly tucked into folds of dark fabric that draped artfully around the figure on the bed, the metal peaking out only in glimpses woven through silk and glinting gently in the light.

A black blindfold wound thrice around Shizuo's head, covering his eyes and twining with strands of his blond hair.

A metal collar circled Shizuo's throat, but it was lined with crimson velvet that curled around the hard edges, forming two perfect red slices across his neck.

His naked flesh is concealed beneath a layer of silk that outlined Shizuo's prone body and the chains that kept him that way.

Without making a conscious decision to do so, Izaya discovered his hands reaching out to carefully slide the fabric off of the body in front of him. It slid down the toned abdomen and the nearly unending legs, revealing the cords of metal and silk that twisted artfully around the flesh before running off in different directions with unknown destinations.

He looked deceptively helpless, this Shizu-chan. For all of his strength, the blonde had never been anything other than lean and lithe, which is why so many people unfamiliar with the face and name of Heijajima Shizuo made the mistake of not seeing him as much of a threat until they were flying into a brick wall or taking a stop sign to the gut. The blindfold obscured the eyes that usually conveyed his bloodlust so effectively, and laying down in the overwhelming bed, held tightly by the array of metal and cloth, his sheer height wasn't even as imposing as it normally would be. All that was left was blonde hair and fair skin decorated with a rosy blush. Izaya, never one to deny aesthetic value, could admit that he looked beautiful.

Without the collar and chains, he'd probably even admit that he looked human.

Entranced, Izaya ran his finger along the edge of the cuffs, gently brushing the skin beneath.

At the gentle touch, Shizuo whimpered. The sound cut through the room, startling Izaya.

He looked again, seeing the beast anew. His skin is flushed and dewy with the heat of the room, but Izaya watched as the flush grew, spreading pink further across his bare skin. His chest moved quickly up and down and his breathing picked up at the simple contact. His lips part. Izaya saw those powerful muscles contract, tense in anticipation. The chains jingled as the links shifted ever so slightly.

It occurred to Izaya that he could kill him. He could take a pillow from the floor and smother him as easy as that. He could push the silk sheet between those lips and laugh as he struggles. He could, but, of course, he's not. What would be the fun in that? What would be the fun after? Without Shizuo around to torment and tease? That's not what Izaya wanted at all. But he could.

Instead, he skimmed a single finger up his arm, from wrist to shoulder, dancing it across the sensitive skin of Shizuo's inner arm. He shuddered at the contact. Izaya can practically feel his own pupils dilate as he eagerly soaked in the sight.

Without another thought, he pushed his hand down on Shizuo's chest to give him the leverage he needed to gracefully straddle the bound man's hips. Izaya hadn't undressed, and the silk sheet still divided them, but just the sudden warmth against his thighs, the shift in perspective—Izaya felt lightheaded from his new position atop the beast. Shizuo moaned as Izaya's ass rubbed against his hardness, futilely trying to lift his own hips enough to create friction.

He really was completely helpless. Izaya smiled. He stared at Shizuo's face as he quickly shed his clothes, knowing Shizuo couldn't tell, couldn't sense anything beyond the wiggling of Izaya's body over his own. Soon, Izaya was naked and he wasted no time in pulling the silk sheet from Shizuo, revealing his full body. His thighs trembled and his hardened cock jutted out, glistening with precum at the tip.

Of course, Izaya had to lick it. He had to rearrange himself to do it, shimmying down Shizuo's body until he could comfortably bend low enough to test the taste. But he couldn't just stop at one, could he? He licked, and licked again, darting out his tongue in teasing touches. Shizuo hadn't made a sound, but, when Izaya looked up, one lip was caught in the other. That wouldn't do at all, so Izaya immediately wrapped his lips around the head of Shizuo's cock and slid down, rubbing his tongue against it as he did. That proved to be too much for Shizuo as Izaya's upturned eyes saw his mouth fall open in a silent shudder. As Izaya continued his work, Shizuo continued silently clench and relax in pleasure.

Izaya kept at his work until he was satisfied that Shizuo was sufficiently slick and on edge.

He then shimmied back up and positioned Shizuo's cock against himself, teasing him more with the heat and friction as Izaya writhed around. He had prepared himself ahead of time, but that didn't mean he couldn't prolong the torment just a bit longer.

Finally, he moved his hips, slowly working himself down. As the pressure closed around him, Shizuo finally gave Izaya what he'd been waiting for and moaned, low and bestial.

It drove Izaya into action, and he began to ride the trapped beast with wild abandon. He dug his fingers into Shizuo's side, but Shizuo just moaned again. He dragged his nails across his skin, and Shizuo just tensed and tried to move enough to thrust up further into Izaya. He bent down and dragged his teeth around his nipples. He wrapped a hand around the metal collar at Shizuo's throat. He rode and rode and rode, but Shizuo only moaned for more.

No matter how hard he tried, Shizuo was so restrained that he could only undulate his hips, trying to press himself closer to Izaya. Even those tiny movements were enough to drive Izaya half-mad as they shifted his angle just the right amount to apply just the right amount of pleasure to his prostate, just enough to make his fingers seize against Shizuo's ribcage as a sudden shock of pleasure shot up his throat and out of his mouth in the form of a desperate moan.

The moan shifted something in Shizuo, molded his face into something beautiful as he rumbled in pleasure. He rose off the bed, pulling each chain link taut as his body contracted and he spilled his seed deep into Izaya. It was too much, of course, and Izaya, completely swept away without the comfort of a game separating himself from his body, he gave completely into the pleasure that coursed through him and he came.

He fell forward as his orgasm left him sated and exhausted. His head found a rest against Shizuo's chest, where Izaya could hear the man's pulse, steady and quick, thrumming through his arteries and veins. He rapidly exhaled, and his breath cooled against Izaya's sweat-slicked brow. Izaya knew that if he looked up, Shizuo's lips would be parted and pink, dry from moaning breaths without a single moistening kiss.

Shizuo's heartbeat slowed against his ear, and Izaya knew that he should pull himself off, leave. Even a normal lover would disentangle his limbs at this point to bask more comfortably in the afterglow, and Izaya isn't sure how long it's going to take Shizuo to pick up on Izaya's presence now that he's not in a haze of lust.

He was enraptured by those lips, dry and chapped no matter how often Shizuo's tongue snuck out between breaths to try to moisten them.

Never one to deny his impulses, Izaya closed the distance between them, licked Shizuo's lips for him, and pressed his own lips against them, firm and sure. There's a pause, startled as if kissing wasn't a usual service granted to Shizuo, but then he deepened the kiss, straining against the metal collar as he worked his way into Izaya's mouth.

Izaya wasn't sure what made him do it—post-orgasm bliss, an unconscious desire, or sheer distraction—but he lifted his hands to curl around Shizuo's face and twine through his hair. Only, of course, face and hair were already tightly held by black silk blindfold, which Izaya's fingers instinctively pushed away—away and off Shizuo's eyes. He didn't even realize at first, not until Shizuo stilled beneath him. By then, it was too late. He pulled back just in time to watch as Shizuo's eyes flickered open and adjusted to the dim light, just in time to watch his reddened lips close tightly in alarm.

Just in time to watch as realization to spread across Shizuo's face.

Izaya didn't wait to find out what would happen next, whether he'd be putting his life in the hands of whoever had ordered the extra-strong chains, whether orgasms really did soothe Shizuo's rage, whether he would be able to sort through his pockets fast enough to find his blade. He didn't wait to find out what Shizuo would say.

He just grabbed his clothes and ran.
