A/N: This is the first of a series of short, unrelated ficlets I'm writing for the Summer Pornathon over on Livejournal. Each week the participants write for a different challenge. The entries have to be between 500 and 750 words. You can read the other entries on the community page at summerpornathon(dot)livejournal(dot)com.

I'll post my entries here each week once the results come out for each challenge, before that all the entries are anon.

Challenge #1 (Sex Toys): Happy Birthday Arthur

Merlin placed two cups of coffee on the bedside table and slipped back into bed to spoon his cool naked body against Arthur's deliciously warm arse.

"Happy birthday," he murmured as he pressed wet kisses onto Arthur's shoulder blades, and his hand flattened against the stomach and slid downwards.

Arthur twisted onto his back and pulled Merlin on top of him, pushing their hips together and grinding his morning wood into Merlin's rapidly filling cock.

"So what's my present then?" he grinned, blue eyes gleaming wickedly, "birthday blow job? Or you could just tie a ribbon round your cock and I could unwrap that?"

Merlin stretched to reach something from under the bed and pulled out a box shaped package, rather haphazardly wrapped in what was clearly Christmas paper.

"Sorry about the snowflakes," he blushed. "I thought I had some plain silver paper left... and I'd left it a bit to the last minute."

Arthur sniffed in disapproval, "you're hopeless Merlin." But his tone was teasing, and he smiled as he sat up to open the present.

As the paper fell away his jaw dropped. He opened the box inside and pulled out a long slender object.

"Merlin... what the fuck?" his face was comical. Merlin resisted the urge to snigger.

"It's a dildo," he said by way of explanation.

"Well duh!" Arthur rolled his eyes. "Thanks for clearing that up. It's pink; and glittery..." he trailed off.

"Well... yeah," Merlin shrugged. "They didn't have that much choice."

Arthur smirked, "I suppose when it's up your arse we won't be able to see the colour."

"Actually Arthur, I was rather intending for it to be going up your arse."

There was a silence, Merlin observed the adam's apple bob in Arthur's throat as he swallowed nervously. He moved to straddle Arthur's lap and wound his hands into the blonde hair.

"Come on babe, it's about time you got over your anxiety about this." He made his best puppy dog eyes at Arthur. "You know I love you fucking me, but I would really like you to bottom occasionally... I thought this would be a way of breaking you in gently." He moved his hands to cup Arthur's jaw and looked at him intently. "I can make it feel amazing for you, I promise."

"Oh fucking hell," Arthur groaned. "You know I can't say no to you when you pout at me like that."

Merlin's eyes lit up and he leaned in, kissing Arthur hungrily and grinding himself into Arthur's lap until they were both flushed and panting.

"No time like the present then!" Merlin wriggled back to sit between Arthur's thighs and grabbed the dildo, shoving the empty box and wrapping onto the floor.

Arthur lay back beneath him and bit his lip. His eyes fixed on the pink, glittery object in trepidation as Merlin reached for lube and slicked his hand and the dildo. He pushed Arthur's legs wider and circled his entrance carefully with cool, slippery fingers. Arthur tensed and then relaxed, allowing the tip of a finger to gain entry. Merlin probed and twisted a little until he felt Arthur relax further, then replaced his fingers with the dildo. He slid it in just a tiny bit, watching his lover's reactions carefully.

Arthur's neglected cock had softened a little, so Merlin wrapped his other hand around his shaft and teased it back to hardness. Arthur's breathing was coming faster now and his eyes glittered. He reached behind and pulled a pillow up to support his head, craning to watch as Merlin worked his cock and gradually pushed the dildo further into Arthur's tight hole.

"Mmm... that actually feels really... oh... really fucking good," Arthur gasped, sounding surprised.

"I told you so," Merlin nodded.

Merlin pushed deeper still, then started to slide it carefully in and out. Arthur was moaning incoherently now, Merlin's name falling from his lips along with fuck and ohh and harder. Merlin angled the dildo slightly differently and Arthur's eyes flew wide and he cried out and came, his body arching helplessly. Merlin's own cock ached and twitched as Arthur's hot release coated his hand. Once he had stopped shuddering, Merlin carefully withdrew the dildo and sat back, surveying the sweaty mess of Arthur spread out beneath him with satisfaction.

"Happy birthday!" he grinned.

"Best present ever," Arthur chuckled, and pulled him down onto his sticky belly for a kiss as Merlin wriggled in half-hearted protest.
