Chapter Text
Gwaine slammed the door to his room so hard he swore it would break. Panting heavily, he leaned against it, mind overwhelmed as he reflected on what had just happened.
OhmyfuckinggodMerlinwhatiswrongwithyou
He cursed the warlock and yet...
The way Merlin had looked in the dim light of the pool. Silently staring from behind Arthur, gaze intent and focused on Gwaine. It was exhilirating. Throwing his head back against the door, Gwaine squeezed his eyes shut and tried not to picture the way Merlin’s hand crept up Arthur’s throat. The way it settled on his jaw, firmly redirecting the larger man’s gaze and controlling him completely without a second thought... the way Arthur obeyed.
A shiver went through him. This is not working; he complained. His scent and phermones were filling the room entirely, kindly reminding him of how horny he was despite just finding his release. The fabric of his pants against his prominent bulge was torturous, yet when he reached down to readjust the friction was too much and he ground down into his hand.
Merlin the things you do to me.
Murmuring a prayer to some kind of gods above, Gwaine relented and unzipped his pants enough for his cock to peak out. Thumbing across the slit, he was already wet and aching. The roughness of his hands a stark contrast to the pool. Then Gwaine was staring at Merlin’s bed. He was one of the only knights who likes sharing with the ‘manservant’, so they usually stayed together. Usually slept together.
His hips twitched as Gwaine recalled the night before. Merlin’s body overwhelming his as he relentlessly thrust inside, deeper and deeper until Gwaine was seeing stars. His hand sped up. The way Merlin had stuffed a neckerchief covered in his own scent in Gwaine’s mouth, forcing him to keep his voice down despite the exhilirating pleasure.
The very same bandana that was lying on Merlin’s bed. Desperately, Gwaine stumbled over to it, restricted by the pants now pooling around his ankles. Picking up the bandana slowly, he stared at it. A part of him knew it would be immoral to use something of Merlins like this. In such a... filthy way.
The larger part of him knew that his cock and brain were both begging for the warlock’s scent, and his permission for release. He settled into bed and began stroking himself hard, thumbing along all the places he was most sensitive while his other hand went to touch his chest.
“Merlin-” He breathed out, inhaling the other man’s dominant scent. It was euphoric. Gwaine was practically drooling.
Then suddenly, footsteps in the hallway. Two sets. One firm, demanding, and the other as though being dragged alone. Gwaine swore, pulling up his pants and attempting to make himself presentable as the door swung open. To his shock, Merlin walked in, practically dragging Arthur behind him.
“Merlin!” Gwaine gasped. They were both still only in bath towels and dripping wet. Merlin had a firm grip on the prince’s neck, and Arthur’s cheeks were flushed so red Gwaine could see it, even in the dim lighting of the room.
“Sit. Now.”
Merlin’s voice left no room for interpretation. Gwaine slumped down onto the bed in a position that was meant to look casual. In case Arthur was looking. Merlin tsked. That was all it took for Gwaine to sink down, off the bed and onto the floor, legs folded beneath him. Burning with shame, it took everything in him to not look at Arthur. To not think about the way the other man would react to seeing this.
Yet Arthur wasn’t doing much. Practically frozen beside Merlin, the blond wasn’t looking anywhere. Harsh footsteps cause Gwaine to look up. He stared, transfixed by the way Merlin strode across the room in an instant. Strong, powerful. Phermones flooding the room. He left Arthur by the door and instead, chose to sit at the head of Gwaine’s bed, silhouetted in darkness.
“Arthur. Watch.”
Arthur’s head whipped up, instantaneously focusing on Merlin. The expression on his face was full of unease. Unease... and a desire to obey. Gwaine recognized that feeling far too well.
“Gwaine. Come. Sit.”
Shame welled up in Gwaine. For a moment, he hesitated. Arthur was definitely watching now. Creeping onto the bed, Merlin motioned for Gwaine to turn around, and helped settle the knight into a position leaning on Merlin’s back. A comforting scent and strong hands enveloped him.
“Arthur. Come. Sit.”
The same command. Arthur startled, seemingly snapping out of it for a moment as his scent spiked and his eyes flared.
“Merlin what the fuck do you think you-”
The warlocks phermones flared, dark, possessive. Absolute.
“-Arthur. Come.”
The prince swallowed. Gwaine tracked the movement with his eyes, then the way Arthur slowly stepped closer, inch by inch until he stood at the side of the bed. Then slowly, as though something was going to jump out and bite him, Arthur settled on the edge of the bed. His hands fidgeted nervously with the towel covering his lap, pulling it as though thrying to cover himself.
It was moments like this that Gwaine could understand the lust Metlin felt in making someone else submit. Arthurs face, beautifully flushed red was entrancing. Strong thick thighs limited in mobility by the towel, almost as thiugh he was restrained. Strong broad chest and large muscles only setving as decoration in the face of Merlins dominance.
I’m so fucking hard right now.
Then he felt Merlins hand. Broad and eager as they crept past his sides and to lie flat on his tighs, slowly creeping towards his aching hard on. With a start, Gwaine realized what the other man’s plan was.
“Merlin wait-“ he tried. The warlock simply leaned forward untill Gwaine could feel the entirety of his chest against his own muscular back, and Merlin’s chin tucked by his neck.
“Something wrong?” Merlin cooed, leaning in close and caressing him softly. His hands began moving uowards, roving as they pleased in soft, possesive circles. Gwaine’s breath hitched and he tried to avoid looking at Arthur.
Easy enough when the blond had his gaze pinned to the bedsheets right by Gwaine’s knee. A part of Gwaine was overwhelmed with shame and worry. What Arthur would think. Yet as he stared at his prince before him, so perfectly responding to Merlin’s pehermones, filling the room with his own in a passionate mix, Gwaine could do nothing but let things play out.
Heat pooled in his stomach at the reality of the situation. How hot things would be if they went the way Merlin wanted them too.
“No. Nothings wrong.” Gwaine answered, choosing to lean back and press his body against Merlin. A silent permission of his will. The raven practically purred with delight and in that moment, slipped his hand into Gwaine’s boxers and drew out his dripping length.
“Mmm!” Gwaine shuddered, hips twitching forward at the sudden touch. Arthur inhaled so sharply it could have been heard from a mile way.
Merlin slowly began stroking Gwaine, rough hands focusing on all of his sensitive spots.
“Arthur.” Merlin called. Only a name. No command. Gwaine could have sworn he saw the other man twitch beneath the towel.
The air was thick with anticipation and Merlin called for the other alpha again.
“Arthur.” This time he continued. “I want you to look at me. At my eyes.”
The blond near immediately looked up at Merlin, then glanced down for only a second at Gwaine’s dick before back at Merlin. The raven tsked.
“I didn’t say you could look at him.”
Arthur flushed and tried to look away again -this time in shame, but then he quickly refocused on Merlin, obeying him.
Another soft gasp escaped Gwaine’s mouth as Merlin stroked him harder, more ferverently. He whined when Merlin dragged his thumb over his tip, red tip pulsing angrily.
“Merlin.” He gasped out, shame having left his body as heat rose. “Please Merlin, let me- let me come.” He pleaded desperately. Arthur jolted but didn’t break eye contact with Merlin.
“Mmm…” Merlin crooned contemplatively into his ear, pressing soft kisses near it. “You can. But only if Arthur watches.”
This time the other mans composure fell and Arthur finally broke eye contact with Merlin to instead stare at the eager and possesive way Merlin was touching Gwaine. A part of Gwaine revelled in it. Revelled in making Arthur simply wait. The fact that Merlin was touching him instead of Arthur.
“Watch.” Merlin commanded to Arthur, then he began stroking Gwaine more intently than he had before. Gwaine cursed and nearly lost his hold on Merlin, hips bucking in response to the mans intensity.
“Fuck!” He cried out desperately. The hand around him tightened and he winced, the pressure now bordering on painful.
“Watch your mouth.” Merlin bit out.
Gwaine shivered, body writhing as he silently begged for Merlin to continue. “I’m sorry I’m sorry!” He gasped out. Arthuer was absolutely hard now, stiff cock tip peaking out from the end of his too small towel.
Then Merlin was touching him again in all the right places and he was cumming harder than he ever had in his life, heat exploding from him as he folded over. He barely had a second to breathe before Merlin was slamming him forward by the small of his back, pressing him against the bed ass up and grabbing Arthur’s face to kiss him fervently.
One of Merlin’s hands crept down to Gwaine’s waist first, griniding against him while the other held Arthur in place. The prince seemed to have finally given in, soft groans resounding from in his chest. He then shifted from holding Gwaine’s waist to creeping up past his head and slipping under Arthur’s towel. Arthur moaned at the contact, loud and sexual in away that only excited Gwaine further.
Still feeling pleasure as Merlin rutted up from behind him, he leaned forward and softly pressed a kiss to the tip of Arthur’s dick.
“Oh my god-“ the prince shouted briefly from above before Merlin was kissing him harder. The pressure on Gwaine’s hips from Merlins grinding increased suddenly and he was thrust forward into Arthur’s pelvis, face practically rubbing against the prince’s dick.
“Better keep up Gwaine.” Merlin teased, reoccupying his free hand with Gwaine’s ass. They had sex last night after Merlin came back to the room straining against his pants.
The stretch as Merlin eased his finger inside was delightful and Gwaine tried to focus more on the man before him.
Pressing kisses up the underside of Arthur’s shaft, he finally enveloped the head in his mouth, hollowing out his cheeks and bobbing his head. Arthur gasped out and one of his hands went down to clutch at Gwaine’s hair, long locks tangling as he did.
The wet sounds enveloped the room as the three of them stayed like that, panting and breathing hard. It was getting difficult to think of anything other than sex between the phermones and physical stimulation Gwaine was experiencing.
Arthur groaned again after Gwaine took him all the way down to the base, throat struggling to accomodate the extra length. “OhmygodsImgonnacome.”
He blurted out, hips now thrusting erratically. Then suddenly Merlin was pulling Gwaine up and backwards, tugging Arthur between them and pressing the larger man forward.
“Merlin what the fuck!” Arthur gasped out. Gwaine turned in time to see Merlin was now behind Arthur, pressing him down and towards Gwaine. The stronger man was resisting, even as Merlin pressed kisses to his ear and a hand crept up his thigh, stroking it soothingly.
Lying on his back and staring up at the pair Gwaine couldn’t help but feel accomplished as he stared at the two beautiful men before him, heat pooling in his gut.
Even if this never happens again... I absolutely need to make the most of it now. His sex addled mind helpfully informed him. Reaching upwards to Arthur’s face he pulled the blond down into a searing kiss. Merlin nodded in praise and sat back on his heels to properly admire Arthur’s ass while Gwaine coddled him.
Then Arthur slowly began grinding against Gwaine, head falling forward as he panted and groaned into the kiss. Then Arthur was easing into Gwaine’s wet hole and moaning so loud the people in the room next door must have heard. Neither of them cared, nor did Merlin.
Instead Gwaine groaned again, nails digging into the strong of Arthur’s back as a thick heat pressed inside of him.
Ohmyfuckinggod.
