The party wound down not long after the fireworks. People made their way slowly back to their houses or designated crashing spots. Dean was eager to get them out, he had things to do. And by 'things' he meant Cas.

Near midnight, Jess departed and Sam safely deposited in his room with his headphones, Charlie and Dorothy tucked away in the guest room, the party cleaned up and the house shut for the night, the two of them made their way up to Dean's room. Dean pressed Cas up against the outside of the door and kissed him fiercely, rocking their hips together. Cas reached down and opened the door behind him, sending them both tumbling into the room, laughing. Dean stumbled to his knees, but Cas stayed on his feet.

With a shout from Cas and a laugh from Dean, Dean lunged for Cas' waist. Throwing Cas up over his shoulder, Dean stood and grabbed his bedroom door.

"Hope you got your headphones on, Sammy! Charlie, Dorothy: payback's a bitch!" Dean shouted down the hall before slamming the door shut. Cas kicked his legs playfully, and reached down to grab Dean's ass. "Hey, now, sir, I'm trying to rescue you. You see," he smirked as he flung Cas down on the bed, "I work for the Lawrence Fire Department. I hear you've got a fire here you need me to put out..." Dean bent down and nuzzled against Cas' neck, climbing up over him. Cas laughed. "Lucky for you, I've got a big hose here that just might do the trick..." Dean bit playfully at Cas.

"That is the worst line I've EVER heard!" Cas laughed harder, rolling his eyes. "How many people has that ever actually worked on?" Cas' eyes were watering with mirth.

"Well, if this goes well," Dean kissed at Cas' neck, "one."

"As in 'you always strike out with that line'? Gee I'm so surprised."

"No. As in 'this is the first time I've been with anyone since I became a firefighter, and I hope it works'," Dean sucked at Cas' earlobe.

"I thought you said you joined after the accident," Cas pushed Dean up so he could see his face. "Are you telling me you haven't dated anyone in almost FOUR YEARS?"

"No," Dean shook his head, eager to go back to his earlier task, "I joined about a year and a half ago. The last person I dated...it only lasted a couple months. She was..." Dean sat up. "You know, I don't really want to talk about her when I have my gorgeous, kinky, boyfriend below me on my bed." Dean bent low over Cas again, nibbling the other side of his neck. "So about that fire..."

Cas laughed and wrapped his arms around Dean's neck as Dean playfully nipped his way down Cas. Dean worked his legs between Cas', spreading them farther apart while he kept up his attentions to the blue-eyed man's neck. He pressed his half-hard cock down against Cas'.

"Mmmmm," Dean hummed against his skin, "Looks like..." he reached his hand down to rub at Castiel's balls, "a two alarm fire..." Cas laughed harder, rocking up into Dean. "Let's see if we can't turn up the heat..." Dean ran his hand up underneath Cas' shirt, freeing the skin of his stomach and torso. Licking his way down, Dean sucked and nipped at the newly exposed flesh.

Cas' laughter turned to a pleased moan at the contact of Dean's lips. Dean smirked against Cas. Cas ran his hands down Dean's back, pulling at his shirt. Catching on quickly, Dean pulled it off over his head and tossed it aside. He turned his attentions back to the man below him, slowly pulling open the button of his jeans.

"Now, sir," Dean began in a playful tone, "can you tell me how this fire started?" Cas chuckled again.

"Mmmm," you see, officer-"

"Captain."

"You're not a captain," Cas laughed down at him.

"I am tonight," Dean breathed against Cas' abdomen.

"CAPTAIN," Cas corrected. "My incredibly hot boyfriend started rubbing up against me, and, well, all that friction created a spark..." He wove his hands through Dean's hair, tugging lightly. Dean moaned as his kisses roamed lower, "before we knew it, things were out of hand..." Cas smiled as Dean's hand found its way inside his jeans to wrap around his quickly hardening cock.

"Well, hopefully I can get things back IN hand," Dean said laughingly as he stroked Cas' length.

"Oh, Dean," Cas groaned rolling his eyes and laughing, "that was TERRIBLE! Even for you!"

"Hey," Dean sat up, "gimme a break. It's hard to be witty when I've got you stretched out in front of me!" Cas quirked an eyebrow.

"So tell me what you want to do to me, instead."

"I'd rather show you." Dean's smug half smile made Cas' cock jump with anticipation. Dean pulled Cas up to sitting and whipped his shirt off in one swift motion. Cas smiled at him and leaned back on his elbows. Warm hands slid down his chest and stomach, coming to rest on the waistband of his jeans. With swift movements, Dean had Cas' jeans and boxers discarded on the floor in no time. Dean slid down Cas' body, off the edge of the bed and knelt down on the floor. With a firm grip on his ass, Dean pulled Cas to the edge of the bed.

Hands itching to work their magic, Dean slid them up Cas' thighs an inch at a time. Cas propped himself up on his elbows to watch as Dean began his ministrations. His eyes locked with Cas', Dean wrapped one hand around his length and stroked up. Cas moaned at the touch, his head dropping back, eyes fluttering shut. They didn't stay shut for long. As Dean wrapped his hot, full lips around the head of Cas' cock, they flew open again. Lifting his head to see Dean once more, Cas locked gazes with the green-eyed man. Dean sucked Cas deep into his mouth, stroking the length that he couldn't fit down his throat.

Cas watched, transfixed, as Dean bobbed up and down his cock, twisting his wrist and flicking his tongue. It was Heaven on Earth and he never wanted it to end. He pushed himself up to sitting, one hand supporting him and the other running through Dean's hair and down his back. With what little nails he had on his long, slender fingers, Cas scratched lightly up Dean's back. Dean arched into the touch with a moan and Cas bucked up into the heat of his mouth at the vibration. Dean swallowed it down, begging for more. Cas rocked his hips up into the warm, wet sanctuary of Dean, moaning his name. They moved with one another for a moment before Cas' hands tugged at Dean's arms.

With a final swallow and lick, Dean pulled off of Cas and crawled back up him. Pressing their lips together, Dean hovered over Cas on all fours while the blue-eyed man reached down and undid his jeans. Working them down Dean's hips, Cas moved down the length of Dean's body with the fabric. Dean sat up to his knees, pulling his jeans and boxer-briefs off one leg at a time. He brought his legs back down to straddle Cas, who was now seated upright near the edge of the bed. Dean knelt over him, and Cas moved back enough to allow himself room to bend down and take the whole length of Dean's hard, pulsing cock into his mouth.

With a quick bob up and down the shaft to wet it, Cas began to suck. Dean moaned Cas' name loudly, and combed his fingers through the dark mess of hair before him. Cas gripped Dean's hips and pulled him forward, working his tongue up the underside of Dean's cock in waves. Sucking, stroking, massaging and moaning, Cas worked Dean up into a trembling mess above him in no time.

Before he could get too carried away, Cas pulled off Dean with an obscene pop and scooted up the bed, beckoning Dean with one finger to follow him. Dean, limbs shivering with barely restrained lust, crawled up over Cas as he laid back on the bed.

Cas allowed Dean a few, brief, moments of deep, needy kisses before placing one hand on his shoulder and the other on the opposite hip. A gentle push, and Dean began to turn above him. When the realization of what Cas wanted sank in, Dean moaned as he moved.

"Oh, god, Cas!" he panted, "I swear you'll be the death of me." Dean placed his hands on either side of Cas' hips, his knees on either side of his head.

"Maybe so," Cas smiled, his voice like gravel, "but not tonight." Cas' hands slid up around Dean's cheeks, pulling them apart and kneading them deeply. His tongue reached out to lick a stripe from the head of Dean's leaking cock all the way up to his balls. When he reached them, Cas sucked one into his mouth, rolling it gently around on his tongue.

"Oh, FUCK, Cas!" Dean shouted, "Oh my god!" Cas sucked harder, pulling off slowly and taking the other one in with a wet slurp. "Jesus-nnngggghh! Oh, CAS!" Cas slid the ball from his mouth with a last, loving lick.

"Come on, Dean," Cas taunted, "thought you were going to show me what you wanted to do to me." Cas licked up the underside of Dean's cock once more, sucking at the precum that leaked from the tip.

That was all the encouragement Dean needed to throw himself into getting Cas off. He dove down at the dripping cock below him, taking in as much as he could. Hollowing his cheeks and bobbing up and down the length, Dean hummed around Castiel. Cas bucked up into the feel and let out a moan of his own.

Soon, both men were bobbing, thrusting, moaning, rubbing and clutching at the other as they sucked each other off. Cas spread his legs wide, giving Dean enough access to tease the tight ring of muscle at Cas' hole with his finger. Dean rocked his hips down, pressing his length down Castiel's throat. Cas swallowed around him, desperate to feel him cum. His moans changed pitch and volume. Dean could tell Cas was close.

Determined to make Cas cum first, Dean redoubled his efforts; moaning, stroking, sucking and teasing with fierceness. Cas, unwilling to be outdone, pulled Dean's hips down until his nose was buried against Dean's balls and the whole of Dean was deep in his mouth. Cas swallowed convulsively around him and Dean's rhythm broke. With a few restrained thrusts, Dean's cum poured down Cas' throat.

The taste of Dean's pleasure sent Cas over the edge. He bucked up into Dean's slippery mouth and came hard. Dean sucked like his life depended on it. They sucked and licked one another until they both became too sensitive, panting and moaning the entire time.

Dean turned himself around and crawled up to Cas. With a long, deep kiss, they traded the tastes of one another. Cas pulled the covers out from underneath himself and wormed his way into bed, pulling Dean in with him.

Sated and sleepy, Dean rolled to his stomach, Cas half draped over him. He pulled his pillow down under his cheek and tucked his hands up underneath it. Something felt wrong. Something SMELLED wrong. His fingers brushed against a foreign fabric. His brow furrowed in confusion, Dean grasped the unfamiliar item and pulled it out.

"The Hell?" Dean sat up and switched on the bedside lamp.

A pair of red satin panties, trimmed in black lace sat in the palm of his hand.

"Where the Hell-?" Dean looked from the panties to his pillow to Cas in confusion. "The fuck is going on?"

Cas sat up and stared at the fabric in Dean's hand. For a moment, panic overtook him. Not again! This couldn't be happening to him again! How could Dean betray him the way Fergus had? His breathing started to become labored. He looked at Dean, expecting to see there the same look that Fergus had worn when he'd been caught. Instead, the shock and confusion he found there made him close his eyes and take a deep, steadying breath. 'This is DEAN,' Cas reminded himself, 'NOT Fergus.' He looked back up at the man next to him.

Dean saw the pain and fear in Cas' eyes. He grabbed him by the shoulders.

"Baby," he said with so much intensity it nearly made him cry, "you KNOW I wouldn't do that to you. I don't want anyone but you. I don't know where these came from, that's the truth. But I'll find out." Cas nodded. Deep down he knew Dean was telling him the truth. To be honest, Dean wasn't ever out of his sight long enough to sneak off and do something like that, anyway.

"Charlie and Dorothy?" Cas offered up weakly.

"Definitely not. Too much fabric for Dorothy and not enough for Charlie." Dean shook his head.

"Should I be worried that you know that?" Cas raised his brows. Dean looked at him flatly.

"Strip poker. And they cheat." Dean climbed out of bed, panties still in hand, and stared down at the sheets as though they owed him an answer. "Who the Hell was in here?" He was so confused. His face changed in an instant. Dean pulled on a pair of boxers and flung open his door. "SAMMY!" He stomped down the hallway and pounded on Sam's door. Cas slipped on his own boxers and watched from behind the door. "SAM," Dean shouted again. He turned at the sound of the guest-room door opening. Charlie and Dorothy's heads peaked out. Dean turned to them, holding out the underwear. "Yours?" he asked accusingly. The women looked at each other then back at Dean. They both shook their heads, wide-eyed. Charlie smirked, Dorothy looked at Dean suspiciously. Sam's door cracked open.

"What?!" Sam shouted back. Dean reached out his hand, the panties dangling from one finger. Dean raised an accusing eyebrow. Sam laughed. "What the Hell are those?"

"Women's underwear," Dean said obviously.

"I can see that," Sam laughed, his brow contracted, "what are you doing with them?"

"They were in my bed. Care to explain?"

"Uh, well, seeing as how, of the two of us, YOU are the one who's worn women's underwear before, maybe you can tell me." Sam smirked. The two women tried to conceal their mirth. Dean dropped his arm. Cas laughed from behind the door. Dean glared at all of them. "Seriously, though, no idea where they came from," Sam chuckled.

"These don't belong to your little smurfcake?" Dean shook the underwear at him.

"Okay, one:" Sam held up a finger. "if Jess and I were having sex, WHY would we be doing it in YOUR BED? Two: those aren't hers." Dean processed that.

"So...if you're not hittin' that, how do you know they aren't hers?" Dean taunted his brother. Sam rolled his eyes.

"She was wearing a white dress, Dean. If she'd been wearing those," Sam pointed at the panties, "I'd have noticed. EVERYONE would have noticed."

"True point," Charlie offered. Dean sent a withering glare at her.

"And, I'm SO not telling you if I'm 'hittin' that' or not." With that Sam closed his door firmly in Dean's face. Dean turned back around to see three faces peeking at him from doors, brows raised in humored surprise and smirks plaster firmly across mouths. Charlie and Dorothy retreated back into their room quickly, leaving Dean standing in the hallway, Cas still watching him.

"Where the fuck did these come from, then?" Dean looked down at the underwear again. Something about them nagged at the back of his mind. He shook it off and walked back to his room. Tossing the panties in the trash, Dean chased Cas back to the bed. "Don't know about you, but I kinda wanna change the sheets." Cas nodded vigorously.

Sheets changed, limbs tangled, the two men drifted off together.

Dean's dreams were plagued with visions of grey eyes full of malice, and sharp nails digging into his flesh until blood ran from the wounds, pooling into red satin and black lace.

He shot up in bed, a cold sweat covering his shivering skin, goosebumps breaking out across his arms. Breathing hard, he wiped a hand across his face.

"Dean," Cas' voice was rough with sleep, "what's wrong?" Dean turned on the lamp again, climbed from bed and moved over to the trash can. Heart still pounding and breath still ragged, Dean bent down and picked up the red underwear. For the first time since he found them, he really looked at them.

Dean's heart skipped a beat.

There was no way.

"Dean," the concern in Cas' voice made him turn around. The panic must have shown on Dean's face. "Dean, what's going on? Are you alright? You look like you've seen a ghost." Cas clambered from the bed and rushed to Dean's side.

"These," Dean held up the panties.

"What about them?" Cas was starting to panic as well.

"I bought these for..." Dean met Cas' eye, "for Bela."

Cas' mouth went dry.

"What?" Cas croaked.

"When we were dating," Dean began, "I bought these for her. They were part of a set. It was a Valentine's Day gift. I saw it in the window, and I bought it..." Cas put a hand on Dean's arm. He shivered at the touch.

"Dean...?"

"Cas, she's...she's bad news." Dean shook his head, brow drawn down. "It didn't end well. She became...obsessive. It was kind of scary, actually. She'd show up at my work and make a scene until Bobby kicked me out to deal with her. Then she'd act like I'd just taken the day off so we could spend it together. The last time I saw her, she showed up at the shop and I refused to come out and talk with her. I had to shut myself in Bobby's office. That's when she grabbed a wrench and started smashing baby. I called the cops. I came out once they arrived and had her calmed. I told her it was over. It had been over for a while, but she just wouldn't accept it. I made it clear: I didn't want to see her again. It was harsh, but I made her repeat it back to me so I knew she understood. Jodi warned her that if she showed up at Singer Auto again, she'd be arrested. I didn't hear from her again.

"Not until the night of the Orchard Street fire. My phone rang at your house before we left, remember?" Dean looked at Cas with unseeing eyes. Cas nodded. "I didn't recognize the number, so I answered it. It was Bela. She was begging me to take her back." Dean's eyes finally found Cas'. "I don't ever want to see her again."

"Dean," Cas began slowly, "do you think those are HERS?"

"I don't know, Cas. They're the same ones I bought her."

"But you said you saw it in the window around Valentine's Day and bought it because of that, right?" Dean nodded. "Did you get them from some big-named store?" Dean nodded again. "So," Cas reasoned, "chances are so did a lot of other people, right?" Dean looked at him pleadingly. "My guess is that one of your guests, who also got this set, snuck into your room and drunkenly defiled your bed in the middle of a party." Dean heaved a sigh of hopeful relief.

"You think so?"

"I think it's a better explanation than those being your ex-girlfriend's," Cas pointed at the panties. "Come on," Cas pulled them from Dean and threw them back in the trash. He kissed him reassuringly, "let's go back to bed."
