Summary: It was one of those things that just happened.

It was one of those things that just happened, Ed wasn't quite sure how or why but it just did. It seemed so natural, to move from laughing in the kitchen, pizza box empty and beer bottles scattered across the table into the bedroom; where teeth scraped down necks and clothing lay scattered around the bed. Knees to the mattress, settled across Roy's chest while Roy sucked him off, both hands clinging to the headboard and panting, staring down at Roy like he'd never seen him before.

Roy's fingers were hot on his thighs, brushing over and clinging to him, digging grooves into the flesh. Ed's fingers curled into the headboard, he wanted to whine but he barely had enough breath left in his lungs to pant. Roy glanced up at Ed, slate colored eyes through heavy lashes, bruised lips and all Ed wanted to do was come right then.

He nearly did but there was a strange clatter from the side of the room and somehow through the haze of sex Ed's instincts fought through and he glanced over.

Castiel was standing against the wall, staring at them in confusion, his mouth sightly open. Ed's hands slipped off the headboard in surprise, frozen on Roy's chest with no idea what to do. He'd never interrupted Ed when he was busy before, Ed didn't know what to do about this. "Cas-?" Ed panted, and the expression on Roy's face was just as confused. Ed's cock slid out of his mouth as he stared up at Ed, then tried to crane his neck to see what had distracted Ed.

"What is it?" Ed asked, somewhere between embarrassed and angry and not sure which one colored his face a dark shade of crimson. He slid off of Roy's chest and Roy propped himself up on his elbows, spotted the angel against the wall and sat up quickly.

"Ed, what the hell-"

"I'll explain later," Ed said.

"Ed," Castiel said hoarsely. His eyes darted to Roy on the bed and as Ed stood up he realized that Castiel was not expecting this at all. "It isn't important," he said, staring unabashedly at Ed. "I will come back later."

"Cas," Ed said, catching the jacket's sleeve before the angel could vanish. The heat hadn't left his face yet and ... he grinned, pulling Castiel toward him. The angel took a confused step forward, tugged by Ed, then relaxed against him as Ed covered Castiel's mouth with his own. "It's been a while," Ed murmured, their foreheads touching.

Roy was sitting on the edge of the bed, trying to figure out if he should be offended or turned on by the kiss Ed was giving this stranger in his bedroom. As Ed started in on his clothes Roy decided on the latter, leaning back on one hand and loosely tugging on his cock as Ed undressed his friend, pulling him toward the bed.

Ed backed Castiel toward the bed, clothing long since abandoned. "I shouldn't," the angel muttered, and then was on his back on the bed, beside Roy. Roy looked down at him, then up at Ed, who was standing between his legs. "Roy, Cas," Ed said by way of introduction, before putting one knee on the bed and leaning over Castiel.

"Stranger things have happened in this bed," Roy said in amusement as Ed kissed Castiel, one hand wrapped around the other man's erection. Ed lifted his head to shoot Roy a worrying grin.

"I doubt it," Ed said.

Roy got to his knees. He was still slightly taller than Ed, but not by much. He leaned over Ed and kissed his shoulder, watching Ed jerk Castiel off critically. "What happened to me fucking you?" he was curious, not disappointed.

Ed lifted his head and Roy took the moment to swoop in for his own kiss, tasting Castiel in Ed's mouth. "Patience," Ed murmured against him.

"It's getting hard to think about much else," Roy said, and took matters into his own hands. He pushed Ed down on top of Castiel, who let out a small cry and Ed exhaled a huge lungful of air as his cock pressed against Castiel's. Roy grinned and pressed a finger into Ed and Ed twitched and groaned into Castiel's throat.

Castiel wrapped his arms around Ed, holding him to his chest while Roy fucked Ed with two fingers. Ed let out small groans into Castiel's skin, hands scrabbling at the covers underneath the angel. "Fuck, Mustang," Ed growled. He could hardly move, every thrust of Roy's fingers alone dragged his cock against Castiel's and he could hardly think of anything, everything was fuzzed out along the edges.

Roy released Ed, both hands now on his hips as he slid home. Ed's noises had long since turned to nonsense as he thrust in. Roy sat back on his heels, pulling Ed off of Castiel and sitting him fully on his lap. Ed pressed his back to Roy's chest, head tilted back as Roy lifted him and settled back finally.

Panting, Castiel crawled to his knees as Roy fucked Ed in front of him, fingers sliding over Ed's thighs as he finally latched on to Ed's cock with one hand. Ed's mouth hung open, he was making little panting gasps with every thrust. Castiel's blue eyes flickered up to Ed's, then to Roy's.

Ed had both hands on Castiel's shoulders and he pushed Castiel back, climbing off of Roy and pinning him to the mattress. He pushed Castiel's legs back to his chest, penetrating him. Castiel let out a low groan, his hands on Ed's forearms. Roy pressed against Ed's back as he filled Castiel, then he was nudging Ed's legs further apart. The angle was awkward, but Roy still managed to get his cock back into Ed. Ed's fingers were digging into Castiel's thighs so hard they were going to bruise but it was Roy who was setting the pace, the rhythm as they fucked. It was a slow, paced slide that Ed frequently tried to speed up but Roy kept it an even pace.

He breathed into Ed's shoulder, biting the soft flesh there and groaning emphatically as Ed tightened around him, shooting off into Castiel with a choked cry. Roy reached around him as he slumped bonelessly into Castiel, wrapping one hand around Castiel's cock and fucking into Ed at the same time. Castiel's head was pressed back into the bed, showing off the line of his jaw and his throat as Roy expertly coaxed the orgasm out of him before allowing himself over the edge, both hands returning to Ed's hips as he came hard. Roy panted into Ed's back as Ed sighed, blissed out against Castiel's chest. "Fuck," he murmured happily as Roy pressed a kiss against the back of his neck. His eyes slid closed and he exhaled, smile genuine and Roy couldn't agree with him more.
