Chapter Text
Sometimes, Arthur itched.
Not the kind where he needed to scratch his bollocks or that spot on his back that he couldn’t quite reach with his fingers, no. It was the kind of itch that, when he noticed a tall, handsome bloke and what he was packing, he thought to himself, I want him to split me open.
Yes, it was that kind of itch, the one where his arsehole would twitch at the sight of a long, fat vegetable when he was doing a grocery run. Or when he counted how many different kinds of tools he could stuff himself with when he walked down the aisle of the local hardware store.
It was the sort of itch that was deep within. The sort where he needed to be fucked well and through until his hole was too loose to close properly for the night.
It was The Itch.
And the only one who could sate him when he was enthralled by the need was his best mate turned lover, Merlin. After all, it was his fault in the first place that Arthur turned out to be so desperate for cock.
Because what had started out as a silly gift from Merlin in their early university days (namely a bulbous flaming red dildo, tied with a blue ribbon at the tip, complete with a note that read: Happy Birthday, prat! Here’s a new stick to replace the stiff one in your arse :D ) had turned out to be a life changing point for Arthur. Mostly due to the events that followed, which he could recall with perfect memory.
…… 🍆🛠️🌽 ……
Nervous from excitement, Arthur pulled out the gift he had hidden in the last drawer of his cabinet. Since his birthday a few weeks ago, that was where it stayed out of sight, but not out of mind. Today was the day he was going to experiment (out of pure curiosity, mind you!) and tore off the perfect blue ribbon along with his roommate’s cheeky note.
Everything was going fine. He had plenty of lube and had read enough on the internet on how to prep himself. Things were going rather smoothly. Until Merlin walked in, without knocking of course, wondering where his bloody scruffy neckerchiefs were—and caught him on the bed, blushing and weeping, with the red-hot dong half-stuck up his arse.
“…I-it’s stuck,” Arthur lamely stuttered, frozen and not knowing what else to say.
Then realised that he probably could’ve just yelled at Merlin to get out, but before he could say that, Merlin already replied.
“…Do you need help?”
Merlin’s unwavering eyes stared at all of him without blinking. Arthur flushed even harder, wishing he could die right there. But not with a dildo sticking out of him.
He tried not to sound so pathetic when he answered with a, “Yes.” And then a heated, “You better not mention this to anyone!”
So Merlin ‘helped’.
“Cabbagehead, the problem’s that you aren’t relaxed enough,” Merlin calmly told him, rubbing his thighs and arse with his warm hands until Arthur felt less anxious.
“You haven’t used enough lube either,” Merlin said, squirting some around Arthur’s stretched opening. “Inside and out,” he added and then proceeded to lightly push the toy in and out of him in small increments, working the lube inside. And adding more lube.
Arthur thought it helped because his muscles were more relaxed and the dildo was moving more easily. Too easily. He didn’t think something was wrong until he felt more pleasantly full than before.
Then realised what was going on.
“Merlin, you idiot! You’re supposed to be taking it out!”
Merlin, sitting between his spread legs, gave him a look of genuine wide-open eyed surprise. “Weren’t you trying to get it in?”
The dildo was already pushed three-quarters inside, stimulating parts of Arthur that hardened his cock and softened his muscles. “I-I was…” he muttered, biting his lower lip.
“And now?” Merlin asked, tone low, gentle, even as he twisted the toy a little.
Arthur’s cock twitched but he wasn’t sure if it was from the motion or Merlin’s sultry voice. Maybe it was both.
“Don’t you want to see this through?” Merlin murmured, slipping the dildo out an inch and pushing it back in twice as much. “You’ve been doing so well and you’re already so close,” Merlin praised, gently rocking the dildo back and forth. “Don’t you want to feel the satisfaction of having it all inside you?”
Merlin’s voice was hypnotic, his look so alluring, and his touch so comforting that Arthur couldn’t refuse what he was offering. Because honestly, he did want to know how being full would feel like.
Then Merlin pushed a final time, sinking the fake dick in completely until his hand palmed the bottom of Arthur’s arse, keeping the toy deep in place. Pleasure sang through Arthur’s body as soon as the last fat bulb of the toy suddenly stretched his opening deliciously wide—and kept it open. He silently came, head thrown back and toes curling, shooting all over himself.
Merlin gave a breathless chuckle. “Did you like that?” he asked, stroking Arthur’s sweaty hair back as he rubbed the palm of his hand hard up against Arthur’s bottom and taint again, shifting the bulb back and forth.
It was too much.
The stimulation made Arthur come one more time and he felt every curve of the dildo, especially the fattest part, as he tightened around it, splattering white across his abdomen again.
Arthur avoided Merlin, and that blasted dildo, for one week after that.
Thanks to close proximity, however, and many mishaps, one thing led to another and they evolved from roommates to friends. Then to friends with benefits before becoming inseparable lovers.
Arthur had thought he was going mad, craving cocks and getting into a relationship with the biggest geek he had ever known, but no. He discovered that he was just a hopeless bottom falling in love with his cheeky, big-eared roommate, who just so happened to have a mouthwateringly large secret in his pants.
Arthur was lucky that Merlin was as experimentive as him though, saying yes to all of his kinks.
Save for one.
“Threesome?” Arthur suggested with an innocent blink one Saturday evening.
Merlin’s smiling face twitched from where they cuddled on their sofa. “No,” he answered.
Then proceeded to clone his willy the next day and double-dicked Arthur with it every night for the whole week straight. It was one of Arthur’s most memorable escapades, which included, on separate days, one fucking machine, spit-roasting, cockwarming, a plethora of vibrating toys, a lot of lube, and a lot more orgasms.
Arthur never thought of threesomes again after that.
…… 🍌🍑🍌……
Presently...
“Who was it this time?” Merlin asked, panting as he pounded Arthur over their dining table.
Head hanging between his shoulders, Arthur groaned as he frantically stroked himself. “M-my fitness trainer,” he stuttered out between gasps, stretched wide over Merlin’s dick as well as the thick, pearled cocksleeve that he wore.
“Percy, the big fellow?” Merlin panted out again, grinding forward, bumping the beads against Arthur’s prostate.
“Yes!” Arthur cried and ground back, arching his spine to let Merlin in as much as possible.
In the past, Merlin would’ve been jealous over any glance Arthur gave someone else’s way and while Arthur had thought of other people’s cocks all the time, it wasn’t them he wanted to go to bed with. Arthur had eventually convinced Merlin completely that he would stay true to their relationship and Merlin came to see Arthur’s wandering eyes as the sign that it was—that there was an itch to scratch.
And Merlin always gave a good, thorough, scratching.
“Did you think of him pounding you over the bench press?” Merlin asked, gripping a handful of Arthur’s globes and squeezing them tight around his buried cock.
The pressure emphasized the very welcome, thick, intrusion in Arthur’s backside. He answered honestly with a shaky breath, “I-I thought of you,” and groaned when Merlin slowly withdrew.
“Ha, of course you did,” Merlin said, more than pleased going by his next sharp thrust inside. Curling over Arthur’s spine, he murmured hot against his ears, “Now, how do you want to finish this?”
Arthur shivered, stopped stroking himself, and grabbed the table edge beyond his head. “Go hard, go fast,” he panted over his shoulder. Then through half-lidded eyes, he ordered, “Fuck me silly.”
Merlin smiled and kissed him sweetly once before leaning over and covering Arthur’s hands with his own hands. Then Merlin slowly drew back and Arthur felt each pearl within him grazing over his sensitive walls. He twitched as Merlin’s cock tip stilled at the entrance, just on the cusp of slipping out, and held his breath.
Without warning, Merlin slammed forward in one thrust. The table shook and Arthur cried out, unable to move as Merlin’s hands anchored him in place on the table, gripping tight over his knuckles and fingers. There would be no escape from the pounding onslaught that would surely follow.
He groaned, squirmed, and screamed as Merlin sank deep into him and hips collided with his buttocks, rubbing him and his nipples against the table, over and over again. He would be wonderfully sore the next day, he knew (hoped for it), but because he was a prat, he would inevitably complain to Merlin. And Merlin, being the doting lover he was, would inevitably console him with hugs and kisses, after chastising him of course.
But right now, Arthur didn’t care. He absolutely loved being railed.
Constantly being emptied and filled with the combined stretch from Merlin’s prick plus the pearled cocksleeve, by the time the clock in their kitchen sounded the hour, Arthur’s insides had received the ravaging it deserved and his rim had become a thorough wreck.
They had both stilled and came, Merlin inside him, adding to the two other loads there, while Arthur’s spend was a mess of a splatter between his belly and the table.
As Merlin slowly withdrew, Arthur shivered and clenched uselessly at trying to keep him in. Without a large cock plugging up his now loose and empty hole, Arthur felt Merlin’s warm seed trail down his shaky thighs.
His waist ached from where Merlin had held him still, slamming into him without abandon and using him like a personal fleshlight. Like the sole purpose of his hole was to be plundered.
But only one man had the privilege of doing so and he wiped Arthur clean before carrying his boneless body to bed.
“Still itchy?” Merlin asked, kissing Arthur’s shoulders as he tucked into him from behind and pulled the blankets over them.
Arthur hummed, sleepy and satisfied, hugging the arms that wrapped around him.
Merlin sighed, a helpless quality to it, as if he knew that Arthur was too tired to answer. So he held him close, pressed against his nape, and whispered like a good night, “I love you.”
And that, without fail, made Arthur’s heart itch more than any hard, throbbing cock.
