Day Twenty Seven: On One of Their Birthdays:

Castiel looked in the mirror, squinting at his reflection. This was him. This was Castiel. He no longer had the angelic face or the sweet, melodic voice of his celestial form.

He was just…human.

Castiel sighed and rubbed his face. Today marked the anniversary of his fall from grace to be by Dean's side. While Cas loved being with Dean and learning about being human, the memories of Heaven lingered in his heart. He missed it, and every day he was reminded of his choice, although he didn't regret it for a second. He could no longer perform even the smallest feats of angelic power. Last time he had attempted to move the clouds to show the shining stars above, nothing had happened.

"Hey grumpy, why the long face?" Dean asked as he nudged past Cas to get to the sink. He was wearing only boxers, his hair a disheveled, slept on mess.

Cas shrugged, but didn't say anything, avoiding eye contact with their reflections. Dean watched him intently in the mirror as he brushed his teeth, concern written on his face.

He spit out his mouthful of white foam and pointed his toothbrush at Cas' reflection, "Something's up. Spit it out. Wait a minute. I know." Dean rinsed the toothpaste from his mouth, threw his toothbrush into the cup, and sprinted out of the bathroom. Cas looked on with interest.

"Well come here, I'm not giving it to you in the bathroom!" called Dean from the next room. Cas smiled and wondered what Dean had for him.

He left the bathroom and went into the bedroom where Dean was kneeling on the floor in front of a box. Cas' curiosity spiked. Anything could be in that box…but what was it? He tried to peek around Dean's shoulders, but he was hunched over enough to hide whatever it was.

"Cas! Come here. I wanna show you something." Dean motioned for Cas to come over.

He tried to hide his excitement by walking slowly, but it turned out to be more of a fast walk. He was at Dean's side in no time. "Hey, hey, no peeking." Dean held out a hand, a sly smile playing on his face.

Cas took a step back and waited. Finally, Dean stood up and held out a lumpy, brown package. "Did you think I was going to forget about your 'birthday', Cas?" He said with a smile.

The former angel's eyes lit up with excitement as he reached out for his 'birthday' gift. He dropped down to the floor and started unwrapping the package. Dean sat down right in front of him, their knees touching. He watched Cas as he tore off the string and ripped through the paper.

His fingers shook with excitement as he tore the last of the paper away. On his lap sat a badly folded article of clothing. "I, um, remembered how you said you needed a proper coat for this London weather so I got you a trench coat. You like it?" Dean looked at Cas hopefully, waiting.

Cas ran his fingers over the material and lifted his head to look at Dean. "This…this is…" Cas bit his bottom lip, his eyes sparkling.

Dean waited for Cas to speak, but there was only one way Cas wanted to thank Dean, and it didn't involve talking.

He tossed the coat to the side and pounced on his boyfriend. He placed both hands on his bare chest and pushed him roughly onto the carpet. Cas positioned himself on top of Dean, straddling him, and leaned in, sealing their lips together.

Dean let out a small gasp of surprise. He gripped Cas' sides in large hands, stroking the soft skin as the former angel rolled his hips, rubbing their clothing clad cocks together. Dean moaned against Cas' lips; they were warm and soft; his angel tasted of minty fresh toothpaste. This certainly wasn't the reaction he was expecting.

Cas' fingers trailed down Dean's toned chest, sending shivers up his spine. He clawed at Cas' sweatpants and tried pulling them down, but Cas smacked his hands away before slipping his own paws into Dean's boxers. He grabbed his ass as he grinded down on him.

Dean squirmed under Cas; his angel turned him on so much it hurt. He wanted nothing more than to rip his clothes off and ravish him. "Jesus, Cas," he breathed. He felt Castiel's smile against his lips as he circled his hips slowly. He squirmed beneath him, needing more friction, but Cas seemed content to keep fucking his hips in those slow, lazy movements.

"Cocktease," he growled.

Cas hummed in agreement and bit his lip gently, soothing the flesh with the trace of his tongue. The little fucker was going to torture him; not gonna happen.

"Oh no, not this time, Cas. It's your birthday, I'm going to treat you." Dean held on to Cas' hips and with ease, rolled him onto his back, reversing their positions. Cas' eyes widened, his pupils lust blown.

Dean wasted no time. He grabbed fistfuls of Cas' pants and yanked them off. "You know," Dean drawled, placing a kiss on Cas' knee, relishing the little whimpers he was making "If you keep wearing my clothes," he paused, trailing kisses on the soft skin of Cas' inner thigh, "I'm not going to have any clean laundry for myself and I'll have to walk around naked all the time."

Cas' fingers scratched at the carpet, "Dean," he breathed. He was wound tight like a spring, heat coiling in his belly. He wanted Dean to touch him, every inch of him, but Dean deliberately steered clear of Cas' throbbing cock. He placed kisses along Cas' jutting hip bones, scraping his teeth along the cut muscle. He drifted lower, nuzzling his length before sucking at the sensitive skin of his balls.

"Dean, please," he groaned, back arching off the carpet. Smiling, Dean decided Cas had taken enough and ran his tongue along the underside of his cock. Cas moaned in relief, relishing the touch. He jutted his hips, begging for Dean to take him. Dean kissed the tip of his cock and slid his tongue into the slit, tasting the sweet drops of pre come budding there.

Dean hummed in satisfaction. The flavor of Cas was addictive. "Baby, you taste so good." Cas squirmed at Dean's words, his head thunking back onto the carpet, his eyes closed, and his mouth opened in ecstasy.

Dean gripped the base of Cas' cock as he suckled at the head. He took him slowly until the tip of his cock touched the back of his throat. Dean hollowed his cheeks and bobbed his head up and down in time with the movements of his hand. It was heaven. It was hell. God, it was perfect.

Cas's hands moved from the carpet to tangle in Dean's soft, short hair as the pleasure rose inside of him. He caressed the back of Dean's head and neck as he rolled his hips, fucking into his mouth. Close; he was so close. Dean moaned against Cas' cock as it hit the back of his throat. The vibration sent Cas over the edge. He arched his back and yelled out as his body quaked with his orgasm.

Dean swallowed every drop like it was the sweetest thing he had ever tasted. He crawled over Cas' body to give him a lingering kiss. They lay side by side, Dean smiling at the glowing boy next to him. Cas looked over, his eyes half lidded; he looked completely blissed out. "Best birthday present…ever."

Dean chuckled, "It's your first birthday present ever." Cas rolled over to snuggle into Dean's side. When he wrapped his legs around him he felt his lover's cock pressed to his hip, rock hard.

"Hm, maybe we should take care of that." He stood, holding his hand out for Dean, who took it. Cas wasted no time to rip off Dean's boxers. He pulled him in for a passionate, hungry kiss. Dean started walking back towards the bed, but Cas stopped him and shook his head, "Oh no, you're coming with me." Cas took Dean's hand and led him to the bathroom.

He shoved Dean into the shower and turned the tap on. Hot water cascaded down on them as Cas pushed Dean against the wall, pressing up against him, and smothering him in wet kisses.

"Fuck…" Dean breathed as Cas sucked on his collarbone, licking the trail of water from it. He grabbed Cas' ass and pulled him against his hips. Their bare cocks brushed against each other, issuing a moan from Dean. He rolled his hips to meet Cas' again and Cas bit down on Dean's shoulder at the raw contact, his spent cock stirring back to life.

"I want you to fuck me," Cas whispered.

Dean's heart raced as Cas turned his back to him, watching mesmerized as the water trailed down his lean back. Dean guided him to the wall of the shower and ran a soothing hand down his back. Cas flattened his palms on the tile and took a deep breath.

Dean looked around the shower, his eyes landing on the conditioner. He poured some into his hand, covering his fingers. He snaked one arm around Cas' middle, forcing him to bend over. He brushed at his entrance, and Cas moaned rocking back into Dean's hand.

Dean gently pushed a finger inside making Cas thrust back, trying to fuck himself on his fingers, begging for more. He inserted another digit, working Cas nice and loose for him. "Oh shit, Dean, please," Cas moaned wantonly.

Dean pulled his fingers out and positioned himself behind Cas. He used his foot to kick open Cas' legs. The blunt head of his cock brushed Cas' hole; he shuddered and groaned. Then very slowly, Dean slid home.

His body exploded with the feeling; Cas was so tight and so perfect around him. Dean stood there losing himself in the feeling, and then he slowly pulled out and slammed back in. Cas clawed at the tile as Dean hit his sweet spot. Dean wrapped his hand around Cas' middle again, finding his arousal. He stroked Cas roughly, fucking him hard. Cas pushed back into Dean, begging for him to keep moving.

Dean wasn't going to last. Cas was so tight and hot around him. Listening to the sounds he made, at the movements he was making, it was too much. Cas threw his head back and his toes curled. Dean was filled with awe that this man was his. "Baby, Cas, so beautiful."

"Dean," He whimpered. His hand slipped so his forearm was resting on the wall. He leaned his head on it and let out another whimper.

Dean quickened, the sight of Cas melting and coming undone because of Dean, made his head spin. The pressure finally exploded, sending Dean over the edge. He gripped Cas' hips and cock as he came. Seconds later, Cas was coming in his hand, crying out Dean's name.

Cas went limp under Dean's hold as he pulled out. Dean hooked an arm under his knees and carried him to the bed. "Be right back," he whispered. He turned and shut off the water and grabbed a towel. When he returned Cas' eyes were closed, but a small smile played on his lips. Dean walked over and starting with his arms, he dried Cas off. He rubbed small circles into Cas' muscles. Working down his arms, over his chest, and down to his legs, he watched Cas sink into the sheets, melt under his touch. Dean loved it; he loved watching Cas come undone, whether it was while he stood behind him thrusting into him, or now with soft, gentle touches.

Cas hummed his approval, "Thank you, Dean, for everything." Dean tossed the towel aside and lay next to Cas. Cas curled into Dean, nuzzling into his chest. Dean wrapped his arms around him and kissed his temple.

"You're welcome, Cas. I love you."

"I love you, too."
