The next morning, Dean returned home early to find two envelopes sitting in the center of his bed. He shut his bedroom door and scanned the room. Advancing slowly, he snatched them up and immediately smiled.

Their test results had arrived.

Dean tore open his envelope and scanned the list to double check what he already knew. He was clean. The other envelope had already been opened and contained Castiel's equally clean results.

In the silence of his room, Dean threw a triumphant fist in the air.

Hell fucking yeah. Sex was on the table.

Dean ripped open the door to find a surprised Cas poised to knock. They both jumped back before talking at once.

"I see you got the results."

"We're both clean!"

Castiel grinned. "This is good news."

Dean laid a loud kiss on his lips. "I'm thinking celebratory blowjobs."

Sam's door flew open. "You guys just bang like bunnies when I'm not here, don't you?"

Dean shook his head. "No. Not yet anyway." At Sam's confused look he waved the papers around and explained, "Test results!"

Sam's mouth tipped in a thoughtful frown. "How responsible of you, Dean."

Dean flushed. "Cas made me."

Sam laughed. "I take that back then. Thank you, Castiel, for making my brother be a responsible grown-up."

"Fuck you, bitch," Dean grumbled.

"Well you did just get that clean bill of health. . ." Sam trailed off with a look of mischief.

Dean gagged. "Oh my god. I threw up a little in my mouth."

"My work as the younger brother is done. I shall inform the council."

Cas threw up his hands. "Was I the only one who didn't get a handbook on how to be an obnoxious sibling?"

"Yes," the brothers answered in unison.

Dean caught Castiel's gaze. The blue seared through him. He shifted on his feet. "Sammy, please tell me you have a study group or something?"

Sam made an amused, yet disgusted, sound. "You're in luck. I'm willing to lie to get out of possibly listening to you have sex."

"You're the best brother ever." Dean clapped a hand on his shoulder.

Sam shook his head. "Whatever, jerk. Just be done in 2 hours. That's enough time, right Cas?"

Cas regarded Dean with a critical eye. "I can be finished in that amount of time."

Dean noticed his finishing wasn't included in the statement. And, motherfucker, it made him hard.

Sam nodded. "All right. I'm going out."

When he reached the end of the hall Dean had a sudden surge of guilt. "Sammy," he called out. "Double date with you and Jo this weekend?"

Surprise flashed on Sam's face before he flashed a smile. "Sure thing. I'll check her schedule."

The door shutting echoed in Dean's head like a gunshot. His muscles tightened up and his stomach rolled.

Cas leaned against the wall. "You're freaking out again."

"I'm sorry," Dean breathed. "I'm just not sure. . . now that we're officially official, I just. . . don't know what to do."

Cas reached up and wrapped his arms around Dean's neck, pulling the man in for a firm hug. "We're going to continue on like we were. Slowly, one or two kinks at a time. But we can do more of the sexual stuff now. You still have your safeword and we're still going to talk about things."

Dean felt his body slump relief. "I'm sorry."

Cas hummed and bit down lightly on Dean's throat, earning a sharp gasp. "Right now, I want you naked and bent over my bed so I can turn that sexy ass of yours pink before I suck your cock. Is that okay?"

Dean choked on his next breath. "Jesus."

"Close," Cas winked. "I was named after an angel after all."

"What a cruel joke to play on humanity at large."

Cas shrugged. "My cousin Gabriel went into porn so it kind of runs in the family."

Dean stared hard before blinking a few times. "Is anyone in your family not a sexual deviant?"

Cas thought for a moment. "Um, Anna's pretty normal I think but I've never asked for details."

Dean shook his head and reached for the hem of his shirt. He met Castiel's heated gaze as he stripped slowly, only breaking eye contact for as long as the material obscured his view. He toyed with the button on his jeans for an extra beat before lowering the zipper with such care he swore he could feel the teeth releasing. A hip wiggle and light shove had them pooled at his ankles to kick into the general direction of his hamper. He ran his fingers along the elastic of his boxer briefs while his tongue mimicked the motion on his lips. There was no way to stop the gasp that left his lips as his overheated cock was exposed to the cool air, precome already beading at the tip. Those also made their way into his room.

Castiel's breathing turned harsh as each item of clothing met its fate. Naked Dean Winchester was a thing of beauty. Jimmy hadn't been far off when he called Dean "Adonis" at the club. The man was the golden ratio come to life. Tan skin and firm muscles all with near perfect symmetry.

His brain barely kicked into gear long enough to put up a hand. "Go put on your cuffs if you like. I have something for you."

Dean's mind whirred as he nodded his understanding. His imagination brought up all sorts of random images as he tried to listen to where Castiel had disappeared down the hall. He raced to his room and snatched the black leather out of the drawer. It took some finesse, but he got both cuffs on without problem before running his finger around the inside to make sure the fit was good like Cas always did.

He stepped back into the hall with apprehension racing through him. What could Cas have to give him?

He didn't expect Cas to hand him a pair of panties. He could feel the blush steal across his chest and race to his cheeks. The silky forest green material felt hot in his palms, the little bits of lace lining the top sending sparks across his fingertips as he touched gently.

"You bought these for me?" he rasped, emotion stealing his voice.

Cas nodded. "They were the closest I could find to your eyes," he said in a quiet voice.

Dean swallowed hard around the lump in his throat, not wanting to cry and ruin the mood. Cas not only accepted his weird panty kink, but went out and purchased him a brand new pair. Not only that, he'd taken time to pick out a specific color instead of grabbing one at random like Dean did.

"Cas," he sighed, leaning in for a kiss, the panties crushing between their bodies.

Castiel pulled back and brushed a thumb across Dean's chin. "Put them on and bend over the bed. I still owe you a punishment for insulting my car, do I not?" He punctuated the question with a raised eyebrow.

Dean realized he was asking permission to take their play to that level tonight. "Yes," he answered without hesitation, the skin on his ass tingling in anticipation.

Castiel nodded his head in the direction of the bedroom and headed to the kitchen, presumably to grab waters.

Dean shoved his legs into the panties, taking no longer than a breath to enjoy the silk holding his cock. He shivered when the lace scraped across the head of his dick, unable to hold back the breathy whine that escaped.

He hurried to lay on his stomach over the edge of the bed, ass high in the air. He was already hard and leaking a wet spot onto the comforter and Cas wasn't even in the room yet.

He heard Castiel turn the corner and enter the room. Bottles of water got set on the side table seconds before a cool hand brushed from his nape to the swell of his ass.

"You look so fucking sexy." Castiel's voice was even deeper with arousal. He took a second to check Dean's cuffs himself, kissing each hand in approval of proper fit.

Dean bit his lip and canted his hips back a little more.

Cas let out a filthy chuckle. "In a second, gorgeous. Do you know why you're being punished?"

Dean sighed. "I was rude."

"Correct. Repeat your safewords for me."

"Red to stop and yellow to slow down." Dean squirmed under Castiel's light touch, eager to get a move on.

"Have you ever done anything in the realm of pain play before?" Cas asked.

Dean whimpered and shook his head.

Cas shushed him carefully. "It's okay. Shh shh. We'll start slow. If it ends up that you don't like it I want you to tell me. Don't hold out on my account. I want you hard and begging for my mouth, not miserable. It's not arousing for me to have you in pain and not enjoying yourself."

"I promise, okay? Just. . . please?" Dean begged.

"Please, what?" Cas teased.

Dean fisted the blankets by his head. "Please spank me, Castiel."

Cas groaned. "You're so pretty when you beg."

Dean couldn't even muster up the brain power to be upset about begging and being called out on it. In fact . . . "Please."

"I'm going to start now," was his warning before Castiel's hand cracked down on his ass.

The sound was more startling than the brief snap of pain. He and Sam had whipped towels at each other harder than that. He doubted it would even really leave a mark. The second smack fell on the opposite cheek with the same force.

"Doing okay?" Cas asked as he rubbed a hand down Dean's silk covered behind.

Dean nodded. "I'm good. More please?"

"I'm going to go harder now," Cas warned lightly.

"Please," Dean whispered.

Cas smacked his hand down more firmly. Dean startled, not used to the sensations, before he moaned into the bed. Heat licked from the spot and spread across his skin, moving straight to his dick. Castiel let another blow fly on the other cheek and Dean was gone.

He could definitely count spanking as something he enjoyed.

"Still good?" Cas asked, rubbing the inflamed skin lightly.

"Fuck yes," Dean groaned. "Please don't stop."

Castiel's hand fell on each side in rapid succession, the blows going straight to Dean's swollen dick. There was a slight pause between each set, enough for Dean to notice but not enough to catch his breath. His hips moved in time with the blows, moving forward under the force before lifting to silently beg for another. The silk panties dragged on his skin with each thrust.

The spanks got harder and Dean felt the moment his body accepted it. A strange calm flowed through him. He could feel the tingly heat spreading across his backside but the sharp snaps of pain were transforming into sparks of pleasure. He moaned a long, low note and spread his legs.

Cas was rubbing his ass now. "So good, Dean. You did so well. Fuck, you're amazing."

Dean felt Cas push at his hip and he rolled over, hissing when his abused ass landed on the bed.

"Scoot up for me," Cas said.

Dean shifted up higher on the bed, lounging against the pillows with a satisfied sigh. He knew he could shake off the fuzzy feeling if he wanted, but he reveled in it.

He felt Cas pull the panties down and off. He forced his eyes open, not wanting to miss the next part.

Cas settled between Dean's legs with a feral grin. He leaned down and licked a hot stripe up the underside of Dean's dick, causing Dean to gasp. Cas licked over every inch of Dean's cock, dipping in to lap precome from the tip every so often. He wrapped his lips around the head and sucked hard, making sure to press his hands to Dean's hips to keep him steady.

Cas flicked his eyes up to Dean before sinking his mouth down an inch at a time. Dean writhed and groaned as his cock slowly disappeared into wet heat. He felt his length hit the back of Castiel's throat an instant before the man swallowed around him.

His hand shot out and buried in the dark hair. He didn't move Castiel's head, he just needed to touch.

Cas groaned at the feeling of Dean's hand in his hair. He may have been the dominant one, but he hardened to diamond levels with a hand in his hair and a cock down his throat. The little breathy whines punctuated by gasping curses only urged him to the edge faster.

Dean whimpered at the vibration racing up his dick. "Cas, close. Please can I come?"

Castiel pulled off abruptly, grinning wickedly at the frustrated keening cry that erupted from Dean's mouth. He thrust two fingers in, cutting off the sound. "Suck."

Dean's eyes went wide as he did. His tongue laved around the digits, moving in between and dragging over the tips.

Cas reluctantly pulled his fingers from Dean's mouth wet pop before descending to suck him again. He pressed a spit slick finger to Dean's entrance and circled in question. When Dean spread his legs and tilted his hips Castiel pressed forward firmly until his finger was entirely inside. He pumped lightly, willing the tight muscles to relax.

Dean whimpered and pumped his hips as much as Cas would let him. Each short thrust had him impaled on Castiel's finger or buried in his mouth. The pleasure built, heightened by endorphins.

Cas slipped another finger into Dean, the two men moaning together. Dean at the feeling of fullness and Cas at the tight heat surrounding his fingers. He pumped in and out a few times, timing the movements with bobs of his head.

He crooked his fingers until he found the spot that made Dean shout. He worked the spot mercilessly as he swirled his tongue and sucked hard.

Dean's breathing came in short gasps as his orgasm raced toward him before shoving him over the edge. He came hard down Castiel's throat with a scream. Cas licked and sucked while pressing on his prostate until Dean begged him to stop.

He crawled up Dean's body to deliver a bruising kiss, suddenly upset that they hadn't done it earlier. He loved kissing Dean and knew it was one of Dean's favorite things.

Dean dipped his tongue into Castiel's mouth, chasing the taste of himself on his boyfriend's tongue.

Cas pulled back and put their foreheads together with a soft sigh. "I'll be back. I need to get you juice. Can you drink that water for me?"

Dean blinked, full awareness still slightly out of his grasp. "What about you?"

Cas glanced down and Dean followed his gaze to see a large damp spot on the front of Castiel's pants.

Oh.

Fuck. That was hot.

Cas shifted Dean under the comforter before leaving the room. Dean laid back and let himself continue to float. Some part of his mind knew he was finally in subspace and he sighed, relaxing into the feeling.

"Dean? I need you to sit up and drink this for me."

Dean let Cas help him into a more upright position. He groaned as the tangy sweetness flowed across his tongue with each gulp.

When he'd drained the glass, Cas let him lay back down before joining him under the blankets. Dean rolled over and threw an arm around his middle, noting Castiel had gotten naked.

Dean hissed when Castiel's hand brushed his ass.

Castiel, the bastard, only chuckled. "I have something to put on that whenever you're ready."

Dean hummed his assent and tilted his head back. He touched Castiel's lips and brought his fingers to his own mouth before snuggling closer with a soft sigh.

Cas trailed his fingers over Dean's skin, lightly touching everything he could. He let several minutes go by before he whispered, "Okay gorgeous boy. I need you to come back to me now. Sam will be home soon."

Dean gave in to the consciousness pushing at him with a groan. He blinked dazedly at Castiel for a second before pulling away to stretch.

Cas smiled at him. "Turn over on your stomach."

Dean did, still deep enough in sub-mode to obey quickly. Cool gel spread across his ass. He could smell the slight aloe scent and something else. "Is that the same stuff you use on sunburns?"

"Yes," Cas answered. "The aloe is good for the inflammation and the light numbing agent will help with the burn."

"But I liked the burn," Dean mumbled into the pillow.

"I know," Cas replied in a soothing tone. "But this is good for your healing. I won't give you another spanking until any marks have healed."

Dean wiggled his ass. "Well then take care of business because we are so doing that again. I can't believe you came in your pants."

"You were very sexy."

"Well next time you can have the blowjob."

Cas leaned down until he was close to Dean's ear. "Do you want to know what I taste like, Dean?"

Dean grunted. "Stop it. After that orgasm I won't be able to get it up again until tomorrow."

"If Sam weren't on his way back I'd take that as a challenge."

"Fuck," Dean cursed as he pressed his twitching dick into the bed.

Cas rubbed circles on Dean's bare back. "We should get dressed. Do you remember what to do to show me you need me?"

Dean sat up and tapped the side of his throat.

Cas pecked a kiss on his lips. "Good. Now let's go make food. You can help me in the kitchen."
