Arthur stood in his chambers and looked down at the belt in dismay; all his efforts over the summer had been undone. First there had been the harvest festival, then the feast of Samhain, the arrival of the druid delegation, then Gwen and Lancelot’s wedding… He’d painstakingly worked his way from the final hole on the belt down two of them, and now he was right back where he'd started.
“What’s wrong?” Merlin asked, with his customary knack for entering the room exactly when Arthur didn’t want him to.
“Nothing.” Arthur whipped the belt behind his back and tried to look as nonchalant as possible, which wasn’t easy as the buckle clanged incriminatingly against his dressing screen.
“Clearly.” Merlin raised his eyebrows, amused. Then, when nothing was forthcoming, he crossed the room and held out a hand, palm up, waiting. Arthur did not yield. Narrowing his eyes, the nosy idiot tried to duck around him, but Arthur turned quickly and backed up. In his haste, however, he fetched up against the wardrobe and Merlin pressed his advantage, bringing his arms up either side of his King to trap him against the solid wood.
Of course he could have got away if he’d really felt like it, Merlin’s magic notwithstanding. But then Merlin leaned in, warm and broad and smelling like home, and brushed his lips lightly, teasingly over Arthur’s. Arthur felt his eyes drift closed, almost against his will, his face tilting up for a proper kiss, even as he murmured “that’s not going to work, you know.”
“I’m offended,” Merlin replied softly, breath warm against Arthur’s waiting mouth. “My intentions are entirely pure, I’ll have you know. I'm only trying to do wicked and terrible things to you.”
“What kind of terrible things?” Arthur asked, a little thrill going through him.
Merlin said, in the low, roughened voice that made Arthur feel, only very slightly, as if his knees might betray him. “Things like taking you right here against this nice, sturdy wardrobe, making you come so hard you can’t walk straight at the feast tonight. Those sorts of things.”
“Oh, well if it’s only those sorts of things,” Arthur said, not at all breathlessly, and kissed him.
It was all going along rather nicely. Arthur had Merlin’s tongue in him, and the promise of other things in him, and he reached up to wrap his arms around the broad shoulders that were pressing him back into the wardrobe door- That was when the forgotten belt clattered to the floor loudly, and Merlin broke away to look down at it. Arthur felt a flush rising across his cheeks as he watched his former manservant putting two and two together.
“Shut up,” he scowled, as the grin broke out over Merlin’s face. “I’m not fat.” He added, rather more petulantly than he’d meant to. Merlin laughed. Arthur scowled harder, the warmth in his face creeping down his neck.
“You’re not fat.” Merlin agreed, amusement still in his voice, “but I have to admit, I do quite like the little extra padding you’ve got now.”
“Shut up.” Arthur said again, crossly, and shoved him.
“No, seriously,” Merlin said, still smiling, but a little wolfishly now. “I like it. I like how it feels against me when I do this,” and he pulled Arthur flush against him and kissed him deeply, thoroughly. He broke off again to murmur, hot and low, “I like how it bunches up under me when I fuck you. When you’re on your back, your cock pressed up between us, and all you can do is lie there and take it and beg me for more.”
“You, er- you do?” Arthur asked, a little thrown by all the blood that had abruptly vacated his brain for more southerly climates. Then, indignation a little spoiled by his raging hard-on, “I’ve never begged!”
“Yes I do and yes you have,” Merlin leaned in to kiss him again, flicking his tongue teasingly along the seam of Arthur’s pouting lips before slipping in, hot and slick and- “and I like how it feels under my hands when I take you from behind, too,” he pulled back to rasp out. Arthur, manfully, did not moan.
“We’re going to be late to the feast, aren’t we?” He managed to say, a tad less casually than he’d been hoping for.
“Whatever gave you that idea?” Merlin asked, eyes bright, and pulled him over to the bed.
