“How’s that?” Merlin asked as he tightened the buckle around Arthur’s wrist.
Arthur gave an experimental tug, hissing as the leather cuff pressed into his forearm.
“That’s good. Green,” he moaned. Merlin grinned and licked a stripe down Arthur’s chest.
Gwaine was lying next to him, lazily stroking his cock, the handle of the bright green butt plug just visible behind his balls. He licked his lips at the sight of Arthur stretched out. Arthur’s arms and legs were fastened to the corners of the bed, his cock standing up proudly on his stomach.
“God, you look good,” Merlin told Arthur, loving the way a blush covered Arthur’s chest at the praise.
“You do, fucking fantastic,” Gwaine added, then leant over to stick his tongue in Arthur’s mouth.
Arthur growled, his hands jerking against his restraints as he automatically tried to reach for Gwaine. Merlin chuckled and gave his bicep a squeeze.
“Ready, Gwaine?” he asked softly. Gwaine nodded eagerly and Merlin stood and walked over to Gwaine’s side. “Hands and knees.”
Scrambling to obey, Gwaine gave a yelp as the large plug shifted at his fast movement. Merlin put a steadying hand on his hip, letting him settle in the position. Then ran a hand down the length of Gwaine’s spine, guiding him down onto his forearms, arse in the air. Tugging at the handle of the plug, he wiggled it out slowly. Gwaine keened, pushing his arse backwards. Smiling, Merlin bent and ran his tongue over Gwaine’s arse cheek.
Dragging his lubed fingers over Gwaine’s hole, he pressed inside, smearing more lube and checking Gwaine was loose enough. Then moved his hand to Arthur’s cock, pumping it until Arthur whined and his stomach muscles clenched as he fought to not move against his restraints.
“You two are gonna be the death of me,” Merlin drawled. He patted Gwaine’s bum encouragingly. “Go on.”
Gwaine straddled Arthur, bending to kiss him again as he sank down onto his cock, both of them moaning. Taking his own throbbing cock in hand, Merlin watched Gwaine begin grinding his hips down, hands braced on Arthur’s chest. Harsh breathing, muttered expletives and the squelch of lube filled the room.
Merlin wandered around the bed, taking in the pair of them rocking together from different angles, all the while slicking his cock. It was a very erotic image. Arthur was squirming, hips thrusting and hands tugging against his cuffs. Merlin put a hand on his shoulder, tapping his fingers in question.
“Green!” Arthur almost shouted in bliss.
“Calm down a bit, you’ll hurt your hands,” he whispered, letting his fingers stroke up into Arthur’s hair and card it back from his face. With a moan, Arthur stilled, his hands balled into fists, his bottom lip firmly between his teeth.
“Better.” Merlin kissed his cheek softly then moved down the bed, positioning himself between Arthur’s spread legs, his cock head nudging at Gwaine’s arse crack. He hooked his thumb into Gwaine alongside Arthur’s cock, giving his rim a tug. Then, fixing his eyes with Arthur’s over Gwaine’s shoulder, slowly inched his cock in too. Gwaine cried out, his head thrown back. Grabbing his hair, Merlin pulled him back for a kiss.
“You good?” he asked.
“Green, yes,” Gwaine whimpered.
“Good.”
Merlin rocked his hips forwards, making Arthur groan as Merlin’s cock slid along his and pushed him deeper into Gwaine. Picking up his pace, Merlin thrust in again and again, harder and deeper. It made Gwaine clench around them, gasping.
“Oh, God, Mer- ah! Amber, amber!”
Merlin’s heart jumped to his throat. He stilled his hips and let go of Gwaine’s hair, hands smoothing over his sides. Amber meant slow down, wait, readjust.
“Shhh, it’s alright, I’ve got you, I’m sorry,” he soothed, fighting to keep the worry from his voice as his heart rate picked up. “What do you need?”
“… minute…” Gwaine gave a wordless cry, his head hanging low, dropping to Arthur’s chest.
“Merlin, untie my hands,” Arthur said urgently.
Merlin started to panic, everything was unravelling, he’d done something wrong. Neither of them were happy.
“Merlin. Calm, it’s ok. I’m still green,” Arthur reassured him, clearly seeing the look on his face. He caught Merlin’s gaze and the love shining in his lust-blown blue eyes helped Merlin calm down. “I want my hands so I can hold Gwaine.”
Merlin gulped and nodded; as much as Arthur loved being strapped down, perhaps this time it hadn’t been the best idea.
He stroked Gwaine’s sweaty hair gently. “Gwaine, I’m gonna pull out to reach Arthur, ok?”
“No, don’t!” Gwaine’s hand shot back, grasping at Merlin’s arse and holding him in place. “I can do it.”
As he leant forwards to reach Arthur’s hands, Merlin wrapped an arm around his waist to hold him steady. Fingers fumbling at the buckles, Gwaine freed Arthur, who immediately reached up and cradled Gwaine’s face.
“Do you want to stop?” Arthur asked carefully.
“No!” Gwaine shouted. “Fuck no! I just” – he rocked his hips a little, letting Arthur and Merlin’s cocks shift in him – “I’m good now. Green. Green, Merlin.”
“You’re sure?”
“Please… green!” He pushed his arse back. “Fuck, oh yes, Merlin. Green! Please!” Gwaine begged incoherently.
Slightly apprehensive, Merlin caught Arthur’s eye. Arthur nodded then Merlin felt him shift, bucking up into Gwaine and making him moan happily.
Merlin pushed Gwaine down, so Arthur was as deep as he could get from this angle. Then tugged out, almost all the way until just his head was tucked in beside Arthur’s cock. And in one steady move, thrust all the way back in. Both of them groaned.
“Green, fuck, yes, green,” Gwaine breathed. His hands spasmed on Arthur’s chest, fingers digging in and making Arthur hiss.
Arthur grabbed Gwaine’s hands and wove their fingers together, letting Gwaine squeeze, knuckles turning white.
“Fuck, Gwaine, you’re incredible,” he muttered.
His hips hitched again, and Merlin had to put his hand on Gwaine’s hip to balance him against Arthur’s erratic thrusts. His other hand fell to Arthur’s thigh, pressing down until Arthur stopped moving.
“Let me,” he said, taking control of their movements.
One hand on Gwaine and one hand on Arthur, Merlin began a steady rhythm. Slowly pulling out and firmly pressing back in, feeling the wonderful friction against Arthur’s cock and the tight wet heat of Gwaine. With each thrust he pushed deeper until his balls were touching Arthur’s with every stroke.
Gwaine was an incoherent mess of moans and cries, his back arching and his hands flexing in Arthur’s.
“How you doing?” Merlin asked, bending forward to kiss the back of Gwaine’s neck.
“Fucking hell. I am so greeeeen!” he cried.
Arthur chuckled, a low breathy sound that had more than an edge of a groan to it. From the sound of it, Merlin guessed he must be close. He angled his hips so that the head of his cock pressed along the length of Arthur’s with each thrust and Arthur gasped.
“Come, Arthur,” Merlin instructed and Arthur was only too eager to oblige.
His hips jerked upwards, making Gwaine bounce, and he shouted his release, eyes squeezed shut and head thrown backwards. He shuddered and trembled, his stomach muscles spasming.
Merlin felt each pulse as Arthur’s spilled inside Gwaine, his cum a hot rush over Merlin’s cock. It was almost enough to push Merlin over the edge but he was determined to get Gwaine off first. He sped up his thrusts. Arthur’s cum was slicking his way as he pounded in, his hand on Gwaine’s hip tightening.
Arthur, now he’d recovered from his orgasm, wrapped his hand around Gwaine’s cock, tugging it in time with Merlin’s thrusts.
“Oh God, yes,” Gwaine slurred. “So good, so green, so… oh, oh!” His arse clenched, making Arthur hiss and Merlin moan. “Green, green, green!” he chanted as his cock spurted all over Arthur’s hand and chest.
Merlin followed him over the edge, thrusting in as deep as he could go and biting gently at Gwaine’s shoulder as his vision whited out. He caught Gwaine as he sagged, holding him up so he didn’t collapse onto the mess on Arthur’s chest, and carefully eased out of him. Arthur slipped out too with a soft sigh.
Stroking soothingly up and down Gwaine’s chest, Merlin let his gaze fall to Arthur. They shared a look of pure love and Arthur blew him a lazy kiss. Then reached over for the towel on the bedside table, wiping his chest clean before chucking it on the floor. Merlin lowered Gwaine to lie on top of Arthur, watching with satisfaction as cum dribbled from his wide hole.
He flopped down onto his back beside Arthur, nuzzling into his shoulder. Arthur chuckled.
“That’s his new thing now isn’t it?” he asked with a smirk, brushing a bit of Gwaine’s hair off his face. “Every time he comes he’ll yell ‘green’.”
Merlin snorted.
“Yep, I will,” Gwaine said, his voice muffled into Arthur’s chest.
Merlin’s snort turned into a full blown laugh.
