Dean lifted his head from Castiel's neck and sighed twisting them around. Castiel groaned fitting in between Dean's thighs and looked down at his earnest expression. It was the first time he noticed the engagement ring hanging between them and Dean wrapped a fist around it tugging on it hard. Castiel gasped when the string gave away and Dean chucked it half way across the room till it hit the wall with a sad thud.

Castiel stared across at it for a long moment before looking down at Dean who kissed him gently.

"I want you inside of me" Dean whispered raking his hands into Cas' hair so it stood up. Castiel smile gently down at him and licked his tongue into his mouth twisting it with his and pulled back grabbing the lube packet. Dean moaned rolling his hip upwards when Castiel moved down and spread the lube across his fingers and slid his finger deep inside him feeling the warm heat and stroked his finger deep inside him. Dean gasped craning his head back when shivers of pain and pleasure ran up and down his spine, he panted harder when Castiel bit down his lip slipping a second with the first and scissored his fingers.

"Yes, god, yes Cas" Dean hissed arching his hips up when he fucked him slowly with his fingers feeling the lube starting to heat up and removed them. Castiel brought his fingers up to his lips sucking down them slowly while Dean watched with a low moan.

"You're so hot" Dean murmured when he removed his fingers from his mouth with a pop.

"I know" Castiel murmured with a smirk and pressed the head of his cock against the line of his ass and waited till Dean greedily accepted him before sheathing inside of him. Dean linked their hands together with a gasp when he pinned them down by his head and fucked him deeply and slowly. His eyes rolled back when Castiel angled his hips perfectly fucking him even deeper and stroking against the prostrate on his second try.

"Yes, Cas, right there, god baby you're so good at this" Dean mumbled rocking against him. Castiel turned his head breathing hot air against his ear and smiling when Dean made a small sound of distress.

"Cas, please, harder" he murmured incoherent words against his cheek. Castiel kissed into the shell of his ear and proceeded fucking him harder into the mattress. Dean cried out in pleasure clinging to his back raking his nails down the sweaty skin, Castiel gasped feeling the scratches and bit down into his shoulder. '

Downstairs, Sam returned with an exhausted dog and listened carefully hearing nothing at first and moved to take off his jacket when he heard the creak of the bed and harsh moans.

"Oh my god" he whispered and grimaced in disgust. "Dammit, Dean"

Sam sighed slowly taking Bones to the back room and shutting him in with bowl of water and food. Bones curled up in his bed with a sigh when he shut the door.

Sam rolled his eyes when the noises increased and he walked back out and locked the door behind him going to stay with a friend. Sam knew this outcome was going to arise but he didn't think it would happen so soon but they both so unpredictable. But if there was one thing Sam knew, he knew that it would all end in tears.

"Yes!" Dean hissed arching against Castiel when he climaxed and panted into his neck as his orgasm swarmed over him. Castiel followed moments after collapsing against Dean who blinked in his hazy daze.

"Oh wow" Dean murmured pressing his lips against his. Castiel moaned nestling into his chest when Dean raked his hands down his back feeling him wriggle and pull out of him. Dean felt the trickle of come coating his ass and down the sheers.

"Don't leave" Dean begged cupping the back of his neck rolling them so they were facing each other and locked their hands and ankles together. Castiel sighed with a nod and let his head rest on the pillow shutting his eyes.

"No sleeping" Dean murmured into his ear. "We have a lot of catching up to do"

"Oh do we now?"

"Yep" Dean murmured sucking a warm path down the side of his neck. Castiel opened his eyes staring into his and Dean saw the sadness wallowing deep into his eyes.

"Let's see if I can remember…" Dean whispered pushing him on his back. Castiel frowned watching him move up and hover over him thoughtfully. Dean moved pressing his lips underneath his ear to the sensitive spot and sucked hard; Castiel gasped gripping his shoulder and stared at him in awe.

"Yep" Dean murmured. "I think I know all your weak spots…but let's see shall we?"

Castiel nodded slowly and gasped when Dean licked his tongue into his clavicle eliciting warm sounds of delight. He travelled down the rest of chest and sucked his nipple until a sharp cry escaped Castiel's lips.

"So sensitive" Dean murmured stroking his thumb over the rosy red bud and smirked gently at Castiel who looked back up at him and stroked his fingers down his cheek.

"I've missed you so much" Dean murmured moving his lips down his chest and down to stomach. Dean's tongue flicked into his belly button making Castiel chuckle and shove at his head gently. Dean ignored him and hummed kissing across his hipbone and feeling Castiel shiver and moan underneath his hands and knew it was another. Castiel gasped when his lips and stubble scratched along his inner thighs and he groaned fisting his hands into the pillow underneath him moaning his name.

Dean bit down into the soft flesh and sucked hard. Castiel gasped looking down at him and groaned dragging him up and claiming his lips once again.

"Do not tease me, Dean"

"Never" Dean murmured sitting up when Castiel climbed and straddled his waist. They continued on well onto the night reconnecting and learning about each other all over again. It was 3am when they collapsed exhausted and sore, Dean choosing to watch Castiel on the pillow next to him sleep. Dean looked across to the open window letting the light of the moon inside which reflected off Castiel's naked back. Dean admired his beauty, the soft arch in his back, his hair ruffled and disarrayed against the pillow, his eyelashes lay gently underneath his eyes, and he looked exhausted but beautiful.

He rolled towards him and pressed his lips gently on his temple. Dean rest against him feeling him breathe against his cheek gently and pulled back to look over him one more time. Dean would not let this go, he refused to have this one night and no more. It was only the beginning.

~0~0~0~

Castiel awoke from his sleep and groaned softly feeling sore and tender. His eyes travelled over to Dean curled next to him and he shut his eyes with a resigned sigh. Castiel moved away wincing at the pain in his lower back and stood collecting his clothes from the floor. He dressed swiftly and sat down gently on the bed staring out of the window.

Dean felt the movement and opened his eyes to see Castiel dressed and sitting in the edge of the bed. He bit his lip and knelt down near him and wrapped an around him.

"You can' regret this"

"Can't I?"

"No because it was meant to happen" Dean murmured into his ear.

Castiel closed his eyes leaning back into his warmth and opened them turning back to look at him.

"I have to go"

"It's 8 in the morning"

"Balthazar will wonder where I am" Castiel said moving out of his arms and moving over to pick up his engagement ring. Dean watched him place it in his pocket and turn back to face him.

"I don't regret it, Dean, but it was wrong of me"

"There's nothing wrong with what we did"

"Tell that to my fiancé" Castiel murmured looking at the door.

Dean knew his intention and crooked his finger beckoning him over. "Come here"

Castiel hesitated before moving over to him and sucking in a sharp breath when he dragged him down into his lap and pulling him into a rough kiss. Castiel teased his bottom lip with his teeth before pushing him back.

"I need to go"

"Fine, I'll call you later"

"I may answer" Castiel whispered kissing him goodbye and walking out of the bedroom. Dean dropped down with a grunt and turned his head burying into his pillow and inhaling his smell.

Castiel returned home to the apartment and sniffed at his clothing and skin smelling sex and Dean. He opened the apartment door and peered around to see no Balthazar yet and closed it softly wincing at the click, Castiel turned his head to see no one and walked into the bedroom to see him still deeply asleep. His feet took him forward and he touched his shoulder and shook him gently.

"What?" Balthazar said with a moan and looked up at him. "What are you doing awake?"

"I woke early" he lied and brushed a hand into his hair. "How are you feeling?"

"Sick, I need coffee" Balthazar said rising up and squinting at the time. "Be a love and make me one"

"I need a shower first but of course" Castiel said stepping back and moving into the bathroom. He leant against the closed door and felt tears coat his eyes before fighting them back and switching on the shower. He turned the water to hot and stepped under it feeling the water beat down on his skin and he washed away the traces that Dean left. Castiel dropped his head to see a dark bruises on his inner thigh and hissed slamming his palm against the tiled wall cursing Dean for leaving his mark on him.

Balthazar sat up rubbing his temples and taking two tablets. Castiel stepped inside wearing nothing but a towel which intrigued Balthazar who admired him.

"I remember last night…I'm sorry, darling"

"It's okay, really, you were drunk"

"Come here"

Castiel stared at him and walked over kneeling down next to him and waited with baited breath when Balthazar stroked a hand across his collarbone.

"Where's your engagement ring?"

"It's…in my pocket"

"Why?"

"I got a shower"

"You never usually take it off in a shower"

"Well today I thought better" Castiel lied with a small smile and moved away pulling out a clean pair of jeans and a black shirt.

"Sexy" Balthazar noted when he nodded and threw the towel in the corner of the room. Castiel didn't know what to say or do but simply walked back out and turned on the kettle. His eyes swam with images of last night and he could still feel Dean's caress down his skin, his lips sucking and biting against his skin and his lips. It made his heart pound faster and he needed it once more. Dean was like a drug, a dangerous, consuming, and life altering drug that he needed all the same. Castiel was so lost in his thoughts he jumped startled when Balthazar touched the base of his spine.

"Only me, are you alright?"

"I'm perfectly content" Castiel responded stirring sugar into the coffee and handing it over. "Just a little jumpy today"

"You smell nice"

"Do I?" he murmured and gasped when Balthazar tugged him against his chest and kissed him softly. Castiel responded for a moment before pulling back and wrinkling his nose.

"You smell of champagne and taste like sick and coffee"

Balthazar chuckled removing his arms and walking away into the bathroom. Castiel walked over snatching up his left phone and dialled Becky's number.

"Hello?"

"I need to speak to you now"

~0~0~0~

Dean hummed along with the radio waiting for his breakfast to cook when the door slammed behind him and he turned to see Sam.

"Sammy!" Dean said brightly. "Pancakes?"

"No, where's Cas?"

"Not here" Dean said with a raised eyebrow. "Why would he be here?"

"Because you fucked him, Dean, I left to give you two privacy and when I came back it wasn't a screaming argument I heard it was you two fucking!" Sam raged at him. "Are you actually insane?"

"Nope, I'm perfectly sane, Sam, it just happened"

"Oh really"

"Yeah, I was fully prepared to kick his stupid ass for the things he was saying to me but we ended up fucking in my bed instead" Dean said taking a bite of the pancake and chewing thoughtfully. "I didn't plan for it and I certainly don't regret it"

"You're…you're so stupid!" Sam cried gesturing his hands at him. "You've broken a relationship, Dean, he is engaged to him! Cas must love him or he wouldn't be betrothed to the guy!"

"You know what, Sam, I am sick to death of hearing that stupid word! Engaged? He's not engaged he's stuck to the man who gave him his life. Cas wouldn't have come to me or even spent a second with me if he loved the man that gave him the ring he wears around his fucking neck" Dean shouted back at him. "I love him"

"I don't doubt that Dean but if Cas wants this then he had to end it with this guy"

"Balthazar" Dean said with a sneer.

"He has to call it off"

"I know he does but if he's behind a wall, Sam, I can't reach him for just yet"

"Dean…"

"I can't, Sam, I need more time"

"To fuck him?"

"I wouldn't count on it" Dean said with a resigned sigh.

"Do you feel no regret?"

"Why should I? It takes two people to tango as they would say and it wasn't just me. So don't start blaming me for what happened"

Sam stood by and watched him leave the kitchen and retreat back upstairs. Dean kicked the door closed and fell back on his bed plugging his earphones in and listening to the hard rock music thud against his eardrums. It was soothing and he drummed his fingers on his stomach still feeling Castiel's presence still next to him.

In the art gallery, Becky stared at Castiel expressionless.

"You had sex with Dean?"

"Yes"

"Last night?

"Yes"

"Holy shit"

"Yes"

Becky sat back and covered her eyes with a loud groan. "Why!"

"We argued badly and things were said over and over again…I went to walk away and the next thing I know I'm kissing him and he's shoving me on the bed and we're having…very hot angry sex…all night"

"All night?"

"I'm exhausted" he murmured with a chuckle. "I know, I know it's wrong and I've cheated on him in the worst way possible and I feel so guilty but at the same time…it doesn't feel wrong"

"Because you love him"

"It still isn't right, Becky"

"So what are you going to do about it?"

"I don't know"

"Listen to me, okay, because you're in a mess, a huge mess, and you need to understand this, Cas, because Balthazar loves you, he loves you so much and I know you love him too but sometimes it isn't enough and there is always someone else. You need to think about what you really want and not just...hot, passionate, sex, as good as it is"

Castiel smirked looking down at his hands. "My mind is in two different places"

"You need to talk to Dean"

"Really?" he murmured softly.

"Yes! You need to sit down and talk to him before you end up making a bigger mess than it already is"

"It seems like I'm always making messes"

Becky hummed in approval and looked around. "Not all the time, I mean look around you, Castiel, look at what you've created and achieved in all these years. Dean hasn't always been there but Balthazar has and he helped create this"

"So I owe him?"

"No but you have to realise what he's done for you"

Castiel looked away from her and sighed deeply knowing she was right and pulled out his cell texting Dean.

We need to talk. Apartment in one hour, everyone is out.

Balthazar had gone to work moody and hung-over so it was empty. Castiel bit his lip at the thought of seeing him since this morning, he returned home and paced feeling anxious and decided to get another shower. Castiel stood in the warm water feeling it pound on top of his head and stared at the swirling water falling down the plughole feeling queasy.

He scrubbed a hand over his eyes and switched it off. Castiel dressed in a pair of grey jogger bottoms and ran a towel into his hair when the door went.

Dean looked around in case anyone was watching and turned when the door opened.

"You're early" Castiel murmured when Dean stared at him open mouthed and wide eyed.

"Yeah…I'm really glad I did come early" Dean murmured stepping inside and closing the door. Castiel moved backwards whilst Dean undressed him with his eyes.

"So I'm here for a talk"

"Yes…yes we need to…" he said trailing off when Dean wrapped a hand around his wrist tugging him to his chest and kissing him into silence. Castiel eagerly responded wrapping his arms around his neck moving his lips against his and moaning when he pushed him against the wall.

"These are amazing" Dean whispered sliding his hands down to his joggers and tugging them down. Castiel smiled when he kicked them away and pressed his body against his feeling his chest heave with his.

"I can't stop thinking about you"

"I've been gone a few hours, we're meant to be talking"

"We are" Dean responded sliding down him and pressing his mouth against the head of his cock. Castiel gasped letting his head fall with a thud when Dean took him down sucking hard. It was a warm heavy weight in Dean's mouth and he hummed around his cock, Castiel gasped bucking his hips and driving his cock harder into his mouth desperate for more heat and more friction. It didn't long for him as he twisted his hands into his short hair and climaxed deep into Deans throat.

Dean swallowed him down eagerly and moved his lips to suck gently on his head. Castiel whimpered at how sensitive he was and tugged at him to move up and kissed him hard.

"Bed" Dean growled shoving him towards the bedroom. Castiel looked behind him to the bedroom and swallowed hard but didn't stop him when he shoved him onto the bed. Castiel just accepted it and soon he was sheathed on Dean pressing him against the headboard as he rode him hard. It was frantic, full of desperate need, and rough enough it had both of them panting for more. Dean buried his face into Castiel's neck when he came hard deep into Castiel, Castiel breathed hard pressing his mouth against his forehead and climaxed stroking white stripes of his come across his stomach.

They lay together in the warm soaked sheets feeling come and sweat soak between them unnoticed.

"I didn't expect to be doing this"

"Didn't you?" Dean breathed cupping his cheek and kissing him tenderly. "I did as soon as you opened that door wearing nothing but them…which I think you should wear more often"

"Because they're easier to get into you pervert" Castiel murmured when Dean shoved him so he was lying on his back with Dean settled in between his thighs.

"I think we need to talk" Dean whispered. "This has happened twice now, it's practically an affair"

"I'm not married"

"Not yet but it's still an affair, baby, and I don't think it's ending anytime soon do you?"

"I don't know" Castiel murmured and closed his eyes when Dean trailed his hands down the side of his ribs feeling him hum in response.

"So what do we do?"

"We do this" Castiel murmured spinning them around and kissing him earnestly. Dean smiled entangling his hand into his hair keeping him in place and didn't know what was going to happen now but whatever it was; it sent an excited thrill for the both of them.

A/N: Ha, naughty behaviour! Enjoy everyone! Hehe!
