Merlin groaned as he felt his lovers' weight behind him, felt lips pressing to the scars on his back as Arthur kissed his way down his spine. He felt his King's hands roam over the back of his thighs, massaging his cheeks. Every part of him was still on fire from having just climaxed, and Arthur seemed to be enjoying how it took only the lightest touch to get a vocal response.
"You can't possibly…" Merlin gasped as he felt Arthur's re-ignited arousal against him. "Not again."
"Can't get enough of you," Arthur mumbled against the dip in his back, before returning his lips to their mission to kiss, suck and bite any inch of skin they could reach. "Never be enough."
"Gods, Arthur," Merlin moaned. "You're trying to kill me."
Arthur grinned, then dipped his head to nip at the back of his lover's thighs, delighting in the cry the bite resulted in. He worked his way down one leg, sucking hard at the back of Merlin's knee, groaning his own desire when Merlin's entire body jerked in response.
He had discovered recently that Merlin had kept a secret from him. While the younger man could only spill once before needing an extended recovery time, he did have the uncanny ability to experience a different sort of climax without needing to be hard or spilling. Arthur was absolutely fascinated with it, and thoroughly enjoyed pushing his lover beyond his limits, though always respectful of that point of sensitivity where pleasure became pain.
He nearly finished himself when Merlin cried out his name as he slipped fingers into the well worked ring of muscle, crooking them to elicit another sharp cry of pleasure as he used his fingers to massage that sweet spot deep inside. His lover needed no further preparation, but he shivered with the thrill of the cries being torn from the spent warlock.
His other hand was running up and down the spine that seemed to melt and relax under his touch. He pushed harder inside the warlock, biting down on the rounded cheek that lifted a little which put it conveniently right next to his mouth.
"Arthur!" Merlin gasped out, shaking his head as euphoria rolled through his exhausted body. He couldn't help but move his hips against the fingers inside him, urging them to move faster. The sensations were overwhelming him, creating new fires where others hadn't yet had a chance to cool. He couldn't tell if it was pleasure or pain and he didn't care. It felt incredible, and he gave himself willingly over to the ministrations of his golden King.
"Merlin," Arthur groaned as he obeyed the request of those moving hips, watching his lover give himself over entirely to the frenzy building in his body. "Gods, you're incredible." He wasn't going to last. It was too exquisite, his own muscles still quivering with the sensations of recently being filled by the younger man mixing with his thrill at his lover's wanton abandonment. He removed his fingers, grinning at the expected mewl of disappointment that came from his warlock. "Oh yes, you're ready," Arthur purred his approval.
He moved over the prone form, lining himself up. He ran one hand up the trembling side, up one arm that was positioned over the raven head, and used his hand to trap both wrists. He entered, tortuously slowly, groaning when Merlin tried to raise himself to meet the entry. He allowed only enough to get a deeper purchase, then exerted his strength to keep the younger man still beneath him, taking his time in drawing out, then plunging back in.
Merlin's cries increased, and Arthur marveled at the sight of his lover being completely overwhelmed in his exhilaration, beyond thought, living only in the moment of his thrusts. He thought he'd never tire of the visual. Taking pity, he moved, curling himself around those slightly raised hips, burying himself over and over with increasing speed. His one hand never left Merlin's wrists while his other rested on the porcelain skin hip to guide him. He was careful to moderate his strength so as not to bruise either, but it was becoming more difficult.
Sweat broke out again at the effort of holding back his own release, but he wanted to hear. "One more time, Love. Oh yessss!" he hissed. "I know you can. One more," Arthur urged, speaking over the younger man's whimper of objection, changing his angle, moaning at the responding cry that came from the man trapped beneath him. Again and again he drove against that tender spot inside.
The tone of the cries changed, becoming garbled, inarticulate, completely lost to the throes of the bliss coursing through him, and Arthur drove harder, gasping out his own encouragement. He felt the body tense suddenly, thrusting itself against the King even as he dove in deeply, and Arthur cried out as muscles clamped and rippled around him. "Ah! Yes! You're so close." He moved faster, determined to drive the warlock over the edge.
When Merlin's final cry of his name was at last dragged out of him, his entire body shuddering from the force of his peak, Arthur shouted his lovers' name, emptying himself deep with one final hard push, making mini thrusts as wave after wave crashed over him until he shuddered one last time.
Panting, Arthur leaned against the spine he had been unable to resist kissing. "Beautiful," he whispered, allowing his body to follow as the boy slumped back down flat on the bed, enjoying the quivering of muscles against his softening member, delighted in the surprised grunts of the aftershocks of pleasure working their way through the smaller frame. He moved his hands to smooth over the strong muscles of the boy's back, smiling as they jumped beneath his hand. He felt himself twitch with renewed interest even as he was still inside the heaven that was his warlock's body.
"Arthur," Merlin whimpered, having felt it too. "Please, no." He wouldn't survive having another peak forced from him, he was sure, and he knew Arthur was capable of doing it. His body seemed designed to respond to the King. He wasn't sure what had gotten into his lover this morning, but he was ready to admit defeat after nearly dying first when Arthur was in him, then when he had screamed down the castle when he spilled inside Arthur, and now this last round that left his entire body boneless and shaking with exertion. He didn't know how Arthur kept managing to peak him even once he was dry, but his King had delighted in abusing it since he'd discovered it. This was not the first session like this. His lover seemed determined to make up for lost time in as short a span as possible.
Chuckling, Arthur slowly eased himself out before slumping to his side next to the exhausted, stunning mess of his lover. He used a finger to brush aside bangs that were still rather long. Merlin opened his eyes, and Arthur shivered at the haze of pleasure that was still visible in them. He leaned in, kissing the swollen lips, using his arms to pull the boneless form to him, marveling in the feel of the boys' skin against his own.
The responding kiss was genuine and loving, but utterly exhausted. Arthur chuckled, burying his nose in the crook of Merlin's neck, inhaling the scent of the two of them on the alabaster skin. "I love you," he murmured fondly.
"Liar," Merlin mumbled sleepily against his collarbone. "Trying to kill me."
Arthur laughed, carding his hands through the sable locks, feeling it relax and ease the warlock into a deep sleep. He'd discovered how much he loved feeling the younger man fall asleep against him, completely confident he was safe from the outside world so long as he was in those arms. Merlin almost never had nightmares when he slept like this. He tightened his hold a little, content to finally have his lover back in his arms. They'd gone through a rocky time lately that had threatened this, and Arthur had sworn he'd never take this simple joy for granted again.
He turned his head when the door was forcefully pushed open, and Ian entered with a tray of food. He frowned. "Ian," he started, but the manservant shook his head.
"Sire, forgiveness, but you have achieved your goal. The entire castle is abuzz with your prowess in the chambers. Enough is enough. You have duties to attend to, and it's nearly noon. Poor Boris has been standing outside your door since dawn, having replaced your breakfast three times in an effort to keep it hot. He doesn't dare interrupt your morning… proclivities."
Arthur snorted. "Maybe you should learn from him."
Ian dipped his head agreeably. "Perhaps, Sire, and were you in your chambers, then your rules would apply. As you are not, and are in fact in my Lord Merlin's chambers, his rules will take precedence. As he has made no such rule against interruption, I am free to go about my duties. Your lunch, Sire. And yes, it's cold. I have other duties to attend to than to run back and forth between the kitchens while you entertain yourselves." He stood straight. "I have taken the liberty of dismissing Boris to his other chores as well, Sire. If it is required, I will help you dress for your day, but it is beyond time it began."
Arthur scowled. "You've been spending too much time with Merlin," he grumbled loudly.
Ian bowed and smiled in genuine appreciation. "Thank you, Sire."
He turned to complete his duties, pointedly ignoring Arthur's stunned expression.
