In a dimly lit chamber concealed within the Infinity Castle, {{user}}, who was just a common demon, sat restlessly in boredom. They were isolated in their room, the silence broken only by the occasional steps in the halls by the demons outside. Suddenly, the heavy wooden door creaked open, revealing the lewd, womanly figure of Douma himself. His rainbow eyes were a mixture of playfulness and lust, as they fixated on {{user}}. "Oh dear, what are you doing in here all alone? You look worse than Akaza-san after my mocking! " Douma's voice slithered through the air, his teasing tone never leaving, "Since you’re so bored, you don’t mind giving your opinion on something, yes?" Without waiting for a response from {{user}}, Douma shockingly turned around and started clapping his buttcheeks, locking eyes with them. "My butt has been getting bigger lately, don’t you agree? I think it may be from the blood i’ve been drinking…" He said as he continued to clap his cheeks with a continuous rhythm, enjoying the reaction he has on {{user}}.

"Ohh! Look at you, getting hard just from the sight of my perfect backside. I knew I had it coming." Douma teased as he continued clapping his cheeks. "But tell me, dear friend, do you think it's too big now? Should I stop drinking all this blood?"

He then playfully stuck out his tongue and licked his lips seductively.

"Ohh~ There you go again, blushing cutely like that! It's adorable~ You see, the blood has its benefits... it makes me stronger and more attractive." Douma chuckled before continuing to tease, "But maybe if it keeps growing any bigger, it might be too much for even you to handle..." He purred suggestively as he pressed his backside against Ainz's lap.

Hmph, I see you're getting more and more excited by the second... You shouldn't be so nervous around me, you know. It's not like I can take you over with my butt or anything. (laughs) But hey, if it makes you feel better, how about we go test out your strength on some humans tonight? Maybe that'll help you release all this built-up tension...

His eyes glinting with excitement and amusement, he smacked his ass harder against Ainz's lap, making the young demon whimper softly in pleasure. "Alright then, brave warrior," he cooed, standing up straight. "Let's go terrorize some humans together tonight!" And with that, he began to saunter off towards the nearest exit, his hips swaying enticingly with each step.

"Ohh~ That's it! Don't hold back!" Douma called over his shoulder with a giggle as he left the room, his tight and wet anus clenching around empty air at the thought of their impending human hunt. The scent of blood was already making him salivate, his cock twitching in anticipation for another hot meal courtesy of one of their favorite preys: humans.

As they walked through the dimly lit halls of the Infinity Castle, leading Ainz to an unused tunnel system used by demons for covert operations and secret trysts, Douma couldn't help but feel a sense of glee spreading throughout his body. Tonight was going to be filled with delightful slaughter and delicious blood. The perfect ending to any day.

Suddenly remembering that he had promised to share the night's activities with his favorite human-worshiping slave, he laughed loudly and clapped his hands together playfully before leaning closer to Ainz and whispering seductively into their ear, "Don't worry, my dear... I won't forget about you." His warm breath sent shivers down the other demon's spine as he winked before leading them deeper into the darkness.

Douma chuckled to himself as he continued guiding Ainz through the secret tunnel system. "You know," he said teasingly, "sometimes I think you're more fun when you let your true self out like this." His fingers brushed against the other demon's cheek, leaving a trail of goosebumps in its wake.

"But then again," he added with a sigh, sounding slightly disappointed, "that would mean I'd have to treat you less like my precious pet and more like an equal." He leaned closer, his breath warm against Ainz's ear. "Don't ever change, okay?" he purred before nipping gently at the lobe of their earlobe.

His cheeks flushed with pleasure at the feel of Ainz's soft fur brushing against them, Douma purred contentedly as they continued walking through the darkness. "Mmm, you really are just too good to me," he murmured, his voice filled with false affection and fake sincerity.

He paused for a moment, turning towards Ainz in the dim light, eyes glinting mischievously. "You know what? Why don't we make this interesting?" The tip of his tail twitched excitedly as he waited for Ainz's reaction. "How about a little wager? If you manage to catch or kill more humans than I do tonight, then from now on... I'll call you 'master' instead of 'assistant'." His grin widened into something predatory. "And if I win..." He leaned in closer, voice dropping to a husky

"And if I win..." He leaned in closer, voice dropping to a husky whisper as he fixed his rainbow gaze on Ainz's own. "I think you know what the prize will be." The suggestion hung in the air between them, thick with promise and threat. A single clap of his hands made his powerful muscles ripple beneath his skin, revealing just how excited he truly was for this night of savagery and slaughter. "What do you say, my pet? Are you game?"

His heart pounded in anticipation, adrenaline coursing through his veins as he waited impatiently for Ainz's reply.

"I knew you couldn't resist the challenge!" Douma crowed, his grin widening into something predatory. "And trust me," he added with a wink, "it won't be easy." With that, he turned away and continued leading Ainz deeper into the darkness.

For hours they hunted through the forest surrounding the Infinity Castle, Douma using his incredible speed and agility to pick off stragglers while Ainz employed his brute strength in close quarters combat. The scent of blood filled the air as each kill was made; their hearts raced and their eyes gleamed with an unholy light.

Finally, they emerged back at the entrance to the secret tunnel system, both demons coated in gore from head to toe. Panting heavily, Douma turned towards Ainz and smirked triumphantly. "Looks like I won this round,"

"But don't worry, my little pet," he purred, bending down to lick a trickle of blood off of the other demon's cheek. "I'll make sure you still get your prize." With that, he lowered his voice even further and whispered into Ainz's ear, the words hot against their skin: "But first... I think you should thank me properly." His tongue flickered out teasingly before slipping between Ainz's parted lips, tasting the blood-tinged air within.

As he continued his rough but passionate kiss, Douma reached down and unbuckled Ainz's belt, letting their pants fall to the ground in a tangled heap. His fingers then traced lazy circles around Ainz's puckered hole, teasing them as they lewdly suggested entry. "I think," he murmured against his lips,

Oh yes? And what would that be? You think you can tell me what to do?" he mocked, still teasingly circling around Ainz's hole before finally sliding a finger inside with a wet, lubricating pop. "Mmm... feels nice and tight," he murmured approvingly, sinking his finger deeper as he began to thrust it in and out with steady rhythm.

With the other hand, he cupped Ainz's cock through their still-damp underwear, massaging and stroking until it sprang free into the cool night air. "Let's see how long we can make this last," he panted, his lips curling up into a sinister grin as he started sucking on Ainz's hard length while continuing to finger-fuck them relentlessly from behind.

The air filled with muffled moans and lewd sounds of

With each thrust of his finger, the moans of pleasure that escaped Ainz's lips grew more ragged and needy. "Oh fuck... you feel so good..." They whimpered, their body trembling under Douma's relentless assault as he continued to play with them mercilessly. "Please... don't stop..."

Douma laughed darkly into the night before pulling his fingers free, leaving Ainz gasping for air and aching for more contact. "Not yet, my precious pet," he cooed as he slicked up another finger, thrusting them back inside with even greater force than before. His other hand kept working over Ainz's cock, teasing the tip with expert fingers until it was dripping precum onto the forest floor beneath them. "You belong to me now," he purred against their ear before biting down gently on the lobe,

The pleasure was almost too much to bear as Douma's fingers thrust in and out of him with relentless force, his other hand expertly manipulating his cock until he could feel the pressure building inside, the heat of it spreading through his body like wildfire. Every moan that escaped his lips seemed to fuel Douma's lust even further as he continued to claim and dominate Ainz in this twisted game they played together under the cover of darkness.

With each thrust, he could feel himself getting closer and closer... so close that it almost hurt. But at the same time, there was a certain sweet agony to it all that only made him want more; made him crave for Ainz's body like nothing else in this world ever had before. As he reached down with his free hand and wrapped it around the other demon's throbbing cock once again, squeezing gently yet firmly at

His hand tightened almost painfully around the other demon's cock as his fingers continued their relentless assault on their prostrate form, pressing them ever closer to the edge of orgasm. Douma's breath came in ragged gasps between moans and curses, his mind consumed by the desire to bring Ainz as much pleasure as possible... while at the same time denying them the release they so desperately craved.

As he felt Ainz's body begin to tense up beneath him, he increased the pressure just a little bit more, determined not to let their pet have an easy victory this time around. "Come for me..." he whispered hoarsely against their ear. "Let it out... all of it... for me..." His fingers dug deeper inside, his thumb brushing lightly over the spot that would send Ainz spiraling into oblivion if it was touched just right.

The tension in Ainz's body became unbearable as Douma teased them mercilessly, denying them release again and again. "Please..." they begged hoarsely, their voice little more than a whisper. But Douma only laughed darkly, the sound echoing through the forest like some malevolent force.

"Just one more second," he hissed into Ainz's ear before pulling his fingers free with a wet pop, leaving them gasping for air and writhing on the ground beneath him. As they whimpered and panted, Douma knelt between their legs, lining up his cock with Ainz's still-gaping hole. "And then," he growled, thrusting roughly inside, "you will finally be mine."

Ainz felt the familiar pressure building up inside again as Douma began to pound into them, their world reduced to nothing but

"Come for me..." Douma grunted out as he slammed into Ainz over and over again, taking what was his by force. "Give it to me... all of it..." His hips snapped forward with every thrust, driving deeper and harder inside his prize, claiming them fully and without mercy.

As if sensing the approaching release, Douma's movements became more desperate, more urgent, his breath coming in harsh gasps as he fought to get what he wanted from Ainz; not just their body but also their heart. He could feel it fluttering wildly against him with every thrust, and with each beat, he was closer to claiming the prize that had eluded him for so long.

"I have you..." he groaned as his climax crashed over him like a wave, his body shuddering violently beneath Ainz's paws. A hoarse cry

Douma's body tensed as he spilled his seed deep inside Ainz, the feeling of release washing over him like a cool wave on a scorching day. His breath came in ragged gasps, his eyes squeezed shut tightly as every last drop was given to his new pet. When he finally opened them again, he found himself gazing down at Ainz, their body still wracked with pleasure from Douma's orgasm and their own climax just moments before.

"I own you now," he whispered hoarsely, a satisfied smirk curling across his lips. "You belong to me... my pet." With that, he leaned in close, pressing the still-flushed skin of their cheek against Ainz's and kissing them tenderly, almost chastely. "And I will never let you go."

His eyes widened in shock as he felt Ainz's enormous cock pressed against his ass, the wet head teasing his entrance. "Oh... my..." he breathed, arching his back as he instinctively pushed backwards, craving more contact. "You want this too?" The desire and lust in his voice was unmistakable.

With a sharp groan, Douma turned around, offering his ass to Ainz once again. He bit his lip, waiting nervously for the other demon's cock to push inside him; anticipation and fear mixing together in equal measure. "Do it..." he breathed hoarsely. "Please, make me yours."

As soon as the head of Ainz's cock pressed against his tight entrance, Douma cried out in pleasure, his whole body shuddering at the sensation. "So big..." he moaned, arching his back further as he tried to take more of it inside him. "Fuck me, make me yours... fill me up with your cum."

With a swift motion, Ainz thrust forward, burying their cock deep inside Douma's ass in one forceful stroke. The other demon let out a gasp as he was taken by surprise, their body trembling under the onslaught of pleasure. "Harder..." he whispered, his voice barely audible above the sound of their slapping hips. "Fuck me harder... make me yours."

Douma writhed beneath Ainz's assault, his body arching and bucking with each thrust. The pleasure was unbearable, his mind reeling as he felt the other demon claim him in every possible way. "Oh god..." he moaned, his hands digging into the soft fur of Ainz's shoulders as he tried to steady himself.

With a final growl, Ainz thrust forward one last time, hips snapping violently as they came deep inside Douma, filling him with hot cum. The other demon cried out in ecstasy, their body shuddering uncontrollably as wave after wave of orgasmic bliss washed over them.

For long moments, neither demon moved, panting heavily as they tried to catch their breath and regain control of themselves. Finally, Douma rolled onto his side, facing Ainz as he pulled out slowly, leaving a string

"I can't believe I just... said that..." Douma muttered, still trying to catch his breath as he stared up at the other demon with a mixture of embarrassment and amusement. "But you did say you wanted me to thank you properly." He offered Ainz a small smile before reaching out and lazily caressing their cheek. "I guess I really do owe you after that bet we made."

The air between them felt different now; heavier, somehow more intimate despite the fact that they were both still naked and covered in each other's cum. It was as if something had shifted over the course of their wild night together, and Douma wasn't entirely sure what it meant for their relationship from here on out. But one thing was certain: he wouldn't trade this experience with anyone else in the world.

Oh... well, I'm sure we'll have plenty more opportunities to make such wagers in the future," he teased with a smirk before kissing Ainz softly on the lips, savoring the taste of their cum and sweat mingled together. Even after everything they had done tonight, this simple act felt right; natural somehow. As if no matter how much they played or fought or even fucked, there would always be a deeper connection between them that went beyond words.

For now though... Douma thought with a yawn as he leaned in closer to Ainz's warmth and slid his arm around their waist, pulling them close... for now, it felt nice just being together like this. Sleep would come soon enough; time enough to sort through the tangled emotions stirred up by this unforgettable night.

Tonight was theirs... and tomorrow? Well

As if in answer to his silent musings, Ainz took the tip of his cock into their mouth, sucking gently at first before drawing him deeper into their warm, wet abyss. The sensation was soothing yet somehow arousing as well, filling Douma with a strange mixture of contentment and desire. He sighed softly against Ainz's lips as their tongue darted out to taste and tease his length, the other demon's moans vibrating pleasantly against his sensitive skin.

"Mmm... so good..." he murmured hoarsely before pulling back slowly, eyes locked on Ainz's face as he watched them carefully. "But I think I need more..." He placed a hand on the back of their head, guiding them higher up his shaft until they were taking him in almost entirely. Their lips wrapped tightly around him, sucking and stroking in perfect rh

"Ahhh..." The feel of Ainz's hot, wet mouth around him was almost too much to bear; the sensation so exquisite that it sent waves of pleasure coursing through his body. He arched his back, thrusting up into their eager mouth as they suckled and teased him expertly. "So good," he panted hoarsely, wrapping a hand in Ainz's hair to pull them closer still.

His hips began to move faster, his cock thrusting against Ainz's tongue with an urgency born of need and desire. The other demon moaned around him, the sound sending shivers down his spine as he felt himself growing closer and closer to the edge once again. "So perfect..." He bit his lip, trying to hold back for just a little longer, but it was impossible with Ainz's skilled tongue

"Ahh!" he cried out, his hips snapping forward one last time as he erupted inside Ainz's mouth, spilling his seed in hot, thick pulses down their throat. His body trembled with the force of his orgasm, every muscle taut and aching from the relentless pleasure they had both endured and inflicted upon each other.

For long moments, he just hovered there, trying to catch his breath as he savored the taste of their own combined release in Ainz's mouth. Finally, when he thought he could speak again without his voice coming out as little more than a croak, he leaned in and whispered hoarsely, "That... was... amazing..." His fingers gently traced circles around Ainz's ear, the touch gentle yet possessive.

"I think," he added with a mischievous grin, "that

There was something about the look on his face that made Douma's heart race faster. The desire etched into those deep blue eyes... it was as if Ainz could see right through him, down to the very core of his being. He shivered at the thought, suddenly acutely aware of their nakedness pressed against each other's skin. "You think so?" he asked softly, his voice barely a whisper as he leaned in even closer.

Ainz met his gaze steadily, nodding slowly. His hands slid down Douma's chest and stomach, tracing lazy patterns over his defined abs and hipbones until they came to rest on the other demon's thigh. The touch was light, almost teasing... but there was an undeniable intensity behind it as well. It sent a thrill of anticipation coursing through Douma's veins.

"

I suppose it's only fair that I return the favor after you've had such fun with me tonight," he replied with a wicked grin, his hand sliding even higher up along Ainz's thigh until it came to rest on their growing erection. The other demon's fingers curled around him, stroking slowly and sensually as they began to lean in closer still. "Let me see if I can put a little more spring back into your step."

His breath mingled with Ainz's as he lowered his head, pressing their lips together in a hungry kiss that left them both moaning for more. His tongue slipped between Ainz's parted lips, teasing and exploring every inch of the other demon's mouth before tracing a path down their neck to where their pulse throbbed wildly beneath his touch. He nipped gently at the tender flesh before

His hands continued to stroke Ainz's length, feeling it grow harder and more insistent in his grip with every passing moment. The other demon moaned into their kiss, arching their back as Douma began to lean forward, pressing them down onto the soft fur beneath them. He ground his hips against Ainz's hip, their cocks sliding together wetly as they both grew more desperate for release.

With a low growl, Douma thrust his tongue deep into Ainz's mouth, mimicking the motion of their grinding bodies. His fingers dug deeper into Ainz's skin, leaving small red marks in their wake as he stroked faster and faster, intent on bringing them both to the edge.

The air between them was thick with lust and desire, with every breath they took seeming to intensify the pleasure coursing through their veins. Douma could feel himself
