Kohaku knew exactly why he’d agreed to Sesshomaru’s surprising offer to come and relax with him in the hot spring after their training. But that didn’t make it a good idea.
And it was certainly one he was regretting now.
The admittedly fantastic view he’d gotten that morning of just what the dog demon had been hiding away in those baggy pants all these years had been great. But you know what would be better? A nice relaxing night at the hot spring where he could ogle the demon’s drop-dead gorgeous body at his leisure.
The obvious problem with that being he’d clearly forgot what just a peek at his master’s manhood had done to him the first time.
An unobscured look at the dog demon’s toned muscles and perfect proportions would have been hard enough to watch without popping a boner. But sitting right next to his glistening body...with his legs wide open...that giant monster of a cock just hanging there, tempting him to watch out of the corner of his eye? He was only human after all!
Kohaku sat with half his body tactically submerged under the warm water, his hands pressing his rock-hard member down to keep it from springing up and surfacing. All as Sesshomaru lounged not even a foot away, sitting at the edge of the water and making zero attempt to cover himself.
And why should he? Demons had a very different sense of modesty compared to humans. To them, the only shame you should feel in regard to sex or arousal is related to dominance and submission. That instinctually driven power dynamic was the only thing that kept demonic mating seasons from turning into a violent free-for-all.
On top of that, Kohaku doubted Sesshomaru had never been accused of being humble. The man likely saw his physical perfection as a gift to everyone around him. And what a gift it was!
The slayer cursed himself. If he’d been thinking with his brains and not his dick, he’d have declined Sesshomaru’s offer. The sign of respect from the mighty Lord of the West simply wasn’t worth being embarrassed twice in one day. He’d already been lucky enough that Sesshomaru had apparently mistaken his arousal this morning for battle-lust.
Which, as a side note, made Kohaku briefly wonder how many times Sesshomaru has popped a boner while fighting if that was his obvious conclusion.
Next to the blushing demon slayer Sesshomaru smirked in amusement, "Kohaku. You should know better than to stay in the water too long after a training session. You’re turning red.”
Kohaku would have loved to get out of the warm water for a moment had the demon lord’s casual and likely accidental strip tease while disrobing not turned the mortal’s cock into the hardest substance known to man. At this point, passing out and drowning was preferable to letting the handsome demon see him like this and realize just how badly Kohaku wanted him.
It certainly didn’t help that he’d jacked off countless times to this exact scenario. He and Sesshomaru, sharing a bath, washing each other’s backs, their hands moving over each other’s bodies, exploring each other until the heat of the moment became too much to bear and one forced the other down into a lustful embrace.
He tried to think of something, anything else as he became more paranoid. Was the steam and water not enough to conceal him? Could Sesshomaru see him right now trying desperately to hide his shame?
Unbeknownst to the slayer, Sesshomaru was well aware of Kohaku’s interest in him. It hadn’t exactly been hard to spot. Any time he’d gone to visit Rin he could always feel Kohaku staring at him, occasionally blushing and looking away or trying to hide a tent forming in his pants.
His thoughts on humans had shifted radically during his time fighting Naraku. He no longer despised them. Hell, there were times when they were downright adorable. Their odd sense of modesty for example.
It wasn’t his place to point out the strangeness of it, so he simply played along despite how illogical it seemed. He’d even covered for the demon slayer this morning when the sight of him in all his glory clearly had the mortal in quite a state.
Sesshomaru, after all, wasn’t devoid of empathy. He’d lived a very long life and in that time he’d been in far too many embarrassing situations to count. Hell, it was the reason he usually abstained from mating season.
Though most would expect the deadliest demon in all of Japan to have a ruthless and dominating track record when it comes to that time of year, the truth is that his overwhelming power was a double-edged sword. During mating season a demon’s body instinctively channels its excess demonic energy into fuel for their libido so that they can last all season long. The problem being that Sesshomaru was insanely powerful compared to most demons. And all that energy turning to lust is nearly impossible to control.
And so, each season he usually retreated to his castle to burn through his desires in solitude rather than risk some unworthy foe getting lucky. In his early years, not understanding why a powerful demon like him was losing to far weaker opponents, Sesshomaru had accidentally given away quite a bit of glory to scores of other demons who made a name from dominating the son of the Great Dog General.
One such incident had occurred rather recently when the now grown kitsune companion of his brother had actually managed to best him in a mating challenge...on his first mating season no less. Sesshomaru had hoped that the kitsune’s inexperience and how early it was in the mating season would have allowed him to come out on top. But it simply added one more humiliating loss to his frustratingly long list of mating season failures.
Losing to a demon on their first mating season was just short of soul crushing, especially to a proud lord like himself. Luckily, the kitsune was so new to being on top that Sesshomaru was able to push back a bit and negotiate a far more equal relationship. Still, even half a season bottoming for someone who’d just barely come of age was utterly humiliating.
Worse, not that he would ever admit it, Sesshomaru found he actually enjoyed himself. Sure, he’d lost but he’d managed to save face enough to make it seem like HE was the one allowing Shippo to top him...as a learning experience.
It felt good to let someone take the reins and be in control. He’d spent the better part of a century cooped up in his castle, constantly on the lookout for enemies as he desperately tried to maintain his image and prestige. After all, a display of weakness during mating season could invite enemies to strike at his lands. So just being able to let go and let his body follow its natural instincts once more was such a relief.
Which led to something else he’d never admit...all those years in his youth, being defeated and conquered by lesser demons...there was a part of him that had grown to like it. Sure, he enjoyed turning his partner into pathetically moaning fuck toy as much as any other demon. But the now Lord of the West being used like a cock-sleeve? He hated how much he loved it.
He was, at his core, a warrior. One who was so powerful that he very rarely tasted defeat. And it does get boring at the top of the mountain. The risk of someone being able to pull him down from his perch…of actually besting him? It was an exciting prospect.
And so here was Kohaku, another warrior. Still in training yet actually worthy of his respect. No longer a boy, but a man coming into his own. A demon slayer trained to track and destroy his kind when called upon. One who clearly desired him...
Still, it was not Sesshomaru’s place to pressure him into something he might not be ready for. But there was nothing wrong with giving him the opportunity.
Rising from his position, Sesshomaru turned his back to the slayer and looked over his shoulder offering a view that he knew would drive the mortal wild, “If you’re going to bathe with me the least you can do is wash my back...Unless there’s something else you wanted to do back there.”
Kohaku, still in his own head, trying to force his raging boner to recede looked over and nearly passed out at the sight of Sesshomaru on his knees seductively peering at him while presenting a perfect view of his back, ass, and a set of hefty balls that hung just off the ground.
The demon slayer drooled at the sight as his brain struggled to process both what he was seeing and Sesshomaru’s obviously coded invitation.
The demon lord turned his head away to allow Kohaku to rise out of the water without him seeing the hard-on the mortal was clearly hiding, “I won’t ask twice.”
Kohaku didn’t even have to tell his body to move. The moment Sesshomaru turned around Kohaku was already rising from the water, his cock springing up and almost loudly smacking his stomach. Keeping his hands on it to hold it in place as he approached, Kohaku moved behind his teacher, wetting a rag and beginning to wash Sesshomaru’s back.
The mortal bit his lip as he got a nice long feel of Sesshomaru’s impossibly smooth porcelain skin while doing his damnedest to control his breathing. He held himself back from all the lustful thoughts flowing through his mind, keeping himself on task and even beginning to think he may have misheard the demon lord.
Sesshomaru was just sitting there after all, not making any move to take things further.
But then he heard his master’s deep calm voice beckoning him, “Lower.”
Kohaku began to sweat nervously as his hands moved to the dog demon’s lower back, eyeing his teacher’s perfectly sculpted rear and the heavy orbs that hung under it.
Seconds ticked by as Kohaku gulped, “How...uh...low do you want me?”
The demon raised his eyebrow in a hidden show of amusement, “How much of me do you think needs to be cleaned?”
“W-Well...” Kohaku’s hands drifted down even further, savoring the feel of the dog demon until he was practically groping Sesshomaru’s ass. Any doubt he had about what was happening was quickly vanishing, “...there are a lot of...hard to reach places.”
Taking a chance, the demon slayer gently pushed up with his hands under the demon’s rear and felt his heart skip a beat as Sesshomaru acquiesced, moving up and allowing Kohaku further access to him.
Sesshomaru almost chuckled to himself as he heard the mortal’s heart nearly beating out of his chest. It was cute and...oddly arousing letting the slayer explore him. Was he suddenly going to stop? Or would he let his lust get the better of him?
He felt Kohaku’s hands caressing his rear and moving to his inner thigh as the demon slowly transitioned, leaning forward until he was on his hands and knees.
The mortal’s voice was still timid and unsure, a small part of him likely doubting if any of this was real or just some heat induced fantasy, “…Lots of places. Including...right here.”
Sesshomaru’s body tensed ever so slightly as he felt Kohaku’s hands spread his cheeks, momentarily allowing the mortal to get a good long look at the demon’s exposed hole. The thought of Kohaku silently gazing in awe at him in such a position filled him with the slightest twinge of embarrassment. The bar for demonic modesty was low…but even it had limits.
Seconds later the demon’s back arched ever so slightly as he felt Kohaku’s tongue touch it. Sesshomaru let a quiet gasp escape him which was all the permission Kohaku needed.
Gripping Sesshomaru’s thighs tightly Kohaku began to very thoroughly “clean” the demon lord’s rear. Not that it needed it as it was pretty clear that Sesshomaru was very attentive to his hygiene and cleanliness, especially in that area.
Sesshomaru’s claws dug into the ground as the mortal ate him out until the dog demon’s massive still flaccid cock began to twitch to life.
Switching up his grip, Kohaku noticed the beginnings of growth in the giant manhood that had gotten him into this whole mess. Parting only momentary to smile in disbelief at the reaction he was getting Kohaku reached under Sesshomaru. Taking hold of the dog demon’s rod, he began to use his rag to “wash” it too, still keeping up the teasing ruse of cleaning his master.
He muttered under his breath as the demon’s cock began to harden, getting bigger, thicker, longer, “So...big. So much...to clean...”
Returning to his task, Kohaku continued eating out the demon with even more vigor until he finally gave up the charade and simply began jacking off his partner.
His strokes, by the very nature of Sesshomaru’s unbelievably massive cock, became longer and longer until he realized his arm simply wasn’t reaching far enough to make the full trip in his position.
So, perhaps not so purely out of necessity, he used his other hand to push down on Sesshomaru’s back.
The demon lord allowed himself to be lowered until he was face down and ass up giving Kohaku full and complete access to him.
The slayer began to practically worship the dog demon stroking Sesshomaru’s long thick rod as he ate him out, occasionally stopping to only to lick his taint and lovingly suck on his giant balls.
Neither man was in a position to realize that they were both in heaven.
It had been quite a while since someone had worshiped Sesshomaru like this. Rin did her best but simply didn’t have the experience, meaning he usually had to take the lead and be quite gentle with her. Kohaku’s sister wasn’t exactly the worshiping type and most of his limited flings with her devolved into an almost demon-like vie for dominance. The closest was his brother’s off-and-on lover who was surprisingly enthusiastic for a human.
And for Kohaku? This was everything he’d wanted to do the second he saw Sesshomaru’s cock this morning lording above him just within reach. It had taken all his willpower not to reach up and start caressing it, feeling it, kissing it, sucking it, and just generally memorizing it so that he could do justice to the demon lord during his late-night fantasies.
If only he had an extra hand right now.
Kohaku’s cock throbbed with need as the slayer gave his complete and undivided attention to his teacher. At least until his begging rod began bouncing, demanding relief.
The slayer panted as one of Sesshomaru’s balls popped out of his mouth, “Lord Sesshomaru, I…I…”
The demon instantly knew what Kohaku wanted and was more than willing to let him have it, “You need not hold back.”
Kohaku hesitated only for a moment as his mind double and triple checked to make sure he’d actually just been given permission to fulfill his wildest fantasies...or at least the ones where he was on top.
Drawing in behind the demon lord Kohaku took hold of himself and pointed his manhood at the dog demon’s well-prepped entrance. He panted as the steam of the hot spring circled around them feeling his tip starting to push in.
“I...can’t…help it. I...”
Slowly, the slayer felt himself pushing in, his imagination having done no justice to what he was feeling right now.
Sesshomaru let out a long quiet sigh of pleasure as Kohaku’s presence pushed inside him, growing inch by inch until the demon lord started to become surprised by just how well-endowed Kohaku was for a human.
Kohaku let out a moan as he finally felt his balls press up against the demon lord’s massive set under him, “So...tight…”
Sesshomaru’s eyes were shut tight as the slightest of smiles crept onto his face, “You’re…bigger than I thought.”
The mortal blushed even deeper than he already was as he looked down and saw the demon lord’s massive rod poking out from under him. He bit out a weak laugh, “You’re one to talk...just look at the size of that thing! So much...bigger than...”
Kohaku trailed off realizing he was about to admit to just how many times he’d fantasized about his partner.
Reaching up and putting his hands on Sesshomaru’s shoulders to keep them pressed down, the mortal gave his first thrust...and another...and another…
Sesshomaru felt the slayer, rather more assertively than he had been expected, pinning him to keep his head down and ass up. Dog demons rarely admitted it, but this position was one they were naturally drawn to in mating season. And that was having QUITE an effect on the demon lord.
It was a perfect storm for him. Kohaku wasn’t a demon so there was zero chance of him bragging about this if he simply asked him not to. And after all the years they’d known each other, despite the mortal being a literally demon slayer, he was completely safe. In fact, him being a slayer actually added to the excitement.
The Lord of the West, being defeated, pinned down, and bred like a pathetic bitch in heat by a demon slayer?
Sesshomaru could feel his resistance melting. After all, why fight it? He had nothing to prove. It wasn’t mating season. Kohaku wasn’t some demon that he needed to establish dominance over or save face from. For the first time in ages he could simply let himself be washed away by the pleasure...and feel himself succumb to the mighty mortal that had managed to conquer him.
Kohaku’s manhood began to seemingly do the impossible, driving away the mighty lord’s icy composure, thrust by thrust.
It would have been quite a sight for the demon slayer, to see a satisfied smile slowly creep onto the face of Lord Sesshomaru. If only he hadn’t been wholly transfixed on his master’s throbbing rod below, “Oh fuck...just look at it...”
Kohaku reached down with one of his hands, letting it rest on the demon’s manhood, feeling it pulse in his grasp as each thrust pushed more and more precum out of it.
“I...I can’t believe I’m doing that. It’s throbbing! Does…it feel good? You’re actually enjoying this too?”
The slayer hadn’t actually expected a response, he was so lost in the moment that he was mostly just talking to himself. But what finally broke him out of his trance was Sesshomaru’s voice and just how different he sounded now, “Y-Yes…it feels…good.”
Kohaku looked up and for the first time in his life, outside his most intense fantasies, actually saw Sesshomaru smiling. And not just smiling, but panting with pleasure as his dog demon tongue hung out and his gorgeous golden eyes beginning to roll up.
The mortal’s eyes went wide with astonishment as his pace increased without him even thinking about it. Kohaku practically drooled over the back of Sesshomaru as he looked down and saw just what effect he was having on the larger and much more powerful demon under him.
He would have loved to have come up with some cool thing to say to the man he’d been fantasizing about for years. He’d certainly thought up quite a few in his spare time. But for whatever reason none of them came to mind. The only thing he could think and repeat was, “Holy shit…holy shit…holy shit!”
Sesshomaru heard Kohaku gushing behind him as the young human began to, perhaps accidentally, absolutely dominate him. Which only added to the fantasy playing through his mind. It wasn’t just some demon slayer that had bested the mighty Lord Sesshomaru...it was one that was still in training!
Having not bothered to resist, Sesshomaru felt his superhuman stamina begin to fail him in a way that would have been a bit more familiar during different time of year. Within minutes the dog demon could feel the beginnings of his climax creeping up on him. Pressure building deep within him, Sesshomaru’s body began to tighten up as the slayer’s frantic speed overwhelmed him.
Kohaku, however, had found his tongue as his brain began to finally catch up and realize that Lord Sesshomaru was actually about to cum, “I can’t believe it! I'm finally fucking Lord Sesshomaru! Oh fuck, I can feel it! You're tightening up! I'm doing it! I'M GONNA MAKE YOU CUM!"
Sesshomaru felt his eyes rolling up even more as the only regret that reared its head was that he couldn’t prolong just how amazing this felt for a little bit longer, “Kohaku! S-Slow...down! I…I…AHHHN!”
Kohaku watched in awe as Sesshomaru’s cock jumped up and down, smacking against the grass under him as surprisingly forceful lances of thick demonic cum began to rocket out of him.
Obeying his teacher, the slayer slowed his thrusts which became deep and forceful, matching the pace of his partner’s orgasmic convulsions.
Sesshomaru’s claws dug into the ground as he felt Kohaku put a hand on his head and press down to keep him in place. Surprised moans left the demon’s fanged mouth as he did his best not to thrash and hurt the fragile mortal atop him.
He could feel the mortal’s balls against his as the demon’s huge family jewels pumped up and down, pushing out an inhuman amount of his seed.
Kohaku watched, biting his lip and blushing with wide eyes, mesmerized by the sight of Lord Sesshomaru’s complete lapse in self-control.
It took nearly two whole minutes for the dog demon’s orgasm to start to die down. But as Sesshomaru’s body finally began to relax, he found himself collapsing to the ground under Kohaku’s weight.
Kohaku followed him down, feeling the demon’s powerful body quivering and sporadically tensing up as aftershocks shook his partner.
Pulling himself tightly to the dog demon’s back and wrapping one arm under Sesshomaru’s chest, Kohaku panted on the demon’s back and began to gently kiss his shoulders and neck.
Sesshomaru’s body quivered letting out the last ropes of thick cum as the hand on his head began to soothingly pet him and the demon slayer lovingly…almost seductively...kissed him.
The demon let out an amused chuckle, “You’re…better...than I expected.”
He heard Kohaku’s ragged breathing as the mortal whispered a confession in his ear, “Lord Sesshomaru…I…you have no idea…how long I’ve wanted this.”
Sesshomaru, of course, knew full well how long. Or at least had a pretty good idea. And it would be a shame to waste all this energy Kohaku suddenly had, “Show me then…”
The demon gasped as Kohaku pulled out of him and flipped him over. Sesshomaru’s still shaking body offered no resistance as the demon slayer almost instantly re-inserted himself, hooked Sesshomaru’s legs, and pressed them back until he and Sesshomaru were nearly eye to eye.
Pushed back into a mating press, the demon lord’s cock twitched as the last strands of cum shot out of it. Taken a bit by surprise, Sesshomaru looked up at the adorable mix of lust and nervousness that was filling his partner’s eyes.
Kohaku bit his lip as he gazed down at the most beautiful man on the planet, blushing and panting under him.
The demon lord sensed the mortal’s hesitation as Kohaku took a moment to simply enjoy the sight of finally seeing Sesshomaru like this.
Sesshomaru’s briefly surprised expression turned into one of amusement. It had been a very long time since he’d willingly submitted to someone without fear of ruining his reputation. And now, it was time to scratch that itch, “Is this what you’ve been sneaking off to think about? You must have built up quite a few ideas about what you’d like to do to me. Go on, let’s see them.”
Kohaku drew in closer to Sesshomaru, their faces barely and inch apart as he stared into the demon’s beautiful predatory eyes, “Alright…how about…this one…”
The demon slayer waited a moment for his partner to object. But the only thing that left the dog demon’s mouth was hot breath mingling with his.
He pushed in and after all the years of waiting finally began to make out with Lord Sesshomaru.
No more words were exchanged as Kohaku began thrusting once more. They moaned into each other’s mouths as their tongues danced. The only thing that stuck out from under the demon slayer where his partner’s open legs and giant demonic cock, wobbling with each motion until eventually succumbing once more as the mortal filled him with his own seed.
They stayed entangled and moving from position to position as Kohaku showed the man of his dreams every way he’d ever wanted to fuck the demon. And even after two days of training, Kohaku’s now unchained desire kept him going for hours and hours until the sun rose revealing the two men laying weary and exhausted in each other’s arms.
