Dean tugged at Cas's coat as their tongues swiveled together. He was still full of raw emotion that was quickly melting into heated lust. He could understand, now, why people sometimes referred to sex as 'making-love.' His whole body was overflowing with adoration for this angel; so much that he felt like he could have sex with him for days without stopping.

They bumped against the glass that contained the lighthouse beacon, hands grasping and hips meeting. Although the morning sunrise on the ocean was a beautiful sight, there just wasn't enough space up here to do anything. At least, not everything Dean wanted to do.

"Cas," he pulled back a little to say, "more space."

The angel understood what he was trying to say. Dean felt a sudden whoosh around him as he blinked. They were suddenly inside the lighthouse, on the ground floor where the spiral staircase began. The tight stone walls made the sound of their breath echo.

As Dean looked back to Cas, he noticed that his eyes were beginning to shine. Dean gulped, taking a step back. Was Cas getting ready to turn all angel-power-house again?

Cas's eyes became electrically sapphire, as his skin began to glow. Dean watched, taking another step back, as the clothes on Cas's body began to burn off; literally. His coat sizzled, breaking apart at the shoulder seams. His tie broke loose from his neck and his pants dropped. All of his clothes tumbled to the floor, leaving him naked and illuminated in the middle of the small room. Dean swallowed again, watching the dark shadows of his wings flash against the stone wall behind him. Dean thought he knew what it was to feel turned on, but apparently he'd been wrong. That was the sexiest damn thing he'd ever seen.

Cas stepped toward him, his hands reaching out. Dean's back was against the wall as he stood motionless. The angel gripped the front of Dean's shirt and tore it open with ease. He ripped all the clothes from Dean's body, the fabric shredding like paper. Dean gasped as he felt himself being exposed. He liked it when Cas took over. His dick seemed to agree, as it was already jutting out with stiffness.

Even though Dean was naked, he still couldn't move. The sight of Cas glowing with his wings braced behind him as his bright eyes shined with intensity, was almost too much for Dean to get a grip on. He felt paralyzed with arousal. Cas placed his hand on Dean's shoulder and gently shoved him down. Dean slid against the wall, sitting on his ass to look up at the angel standing over him.

Cas smiled a little as he knelt down to straddle Dean's legs. Dean watched the wings behind Cas move to help him steady himself. Cas's glowing eyes were almost hypnotizing as they bore down into him. He held his hand open in front of Dean's face.

"Spit," he said, voice echoing against the stone.

Spit? Dean struggled to remember what the word meant for a moment, before gathering the saliva in his mouth. He spit it into Cas's open palm. The smile remained on the angel's face as he brought his wet hand down to grab Dean's dick. Dean sighed erotically, realizing Cas was lubing him up. He was proud of Cas for remembering.

Cas held onto Dean's shoulders as he slid down onto him. Dean groaned at the feeling of entering the angel's heated body. He thrust a little, unable to stop himself. Cas felt it, his mouth falling open to gasp. They panted into each others faces as Dean rocked into him. Cas whimpered as his own, glowing dick bounced around between them. Dean reached down and grabbed it, feeling that it was rock hard and nearly as hot as fire. Cas gasped out loud, looking down at it. From what Dean could gather, Cas was bound to be more sensitive to touch when he was celestial. Dean gently tugged on Cas's dick as he thrust into him.

"Dean," the angel moaned.

The sound bounced violently off the walls, causing Dean to cover his ear with his free hand. He heard the sound of glass shattering high above them. Although it was extremely loud, the sound of Cas crying his name gave Dean chills. There was ringing in Dean's ears as he kept pounding into Cas. He was quickly striding toward the finish.

Cas let his head fall back as he bounced, the wings behind him curving inward. Dean savored the sight, wanting so badly to let Cas come. His glowing chest heaved in front of Dean's face, heat radiating from it. Dean went faster, feeling Cas's muscles tighten around his dick. He was so close...

"Cas," he sighed, "ahhh...baby,...yes!..."

Dean groaned out loud as he finally reached the top, his dick pulsing. Cas cried out almost instantly after him, one of his hands falling to his lower stomach. In the midst of Dean's orgasm, he felt Cas's dick begin to pulse in his hand. Hot, white fluid shot from it, landing everywhere between them. Dean used the sight of Cas's pleasure to linger in his own. He loved being able to make Cas loose it. His thrusting slowed to a stop as he saw the angel holding his stomach again. There was just no way that Cas could actually feel that...right?

"Baby," Dean said, trying to catch his breath, "can you really feel me come?"

"I...feel...everything,...Dean," he panted, his wings seeming to move with his every breath.

Dean believed it. He reached up to touch the angel's illuminated face. It felt hot, but smooth and moist. Cas gasped a little, pressing his cheek harder against it. He acted like it was the first time his face had ever been touched...maybe it was true. Maybe his angelic form had never really been touched. Dean leaned up to gently press his lips to Cas's. Cas flinched a little before kissing back with caution. Maybe this was the first kiss he'd ever felt as an angel. Dean felt oddly smug to be his first.

Cas pulled back, his glow slowly fading out. Dean watched the dark wings on the wall fold back as they disappeared. Cas's eyes closed as he fell against Dean, panting and trembling. Dean wrapped his arms around him, knowing it was hard for him to come back down from being so high. He kissed Cas's damp forehead while they sat on the stone floor in momentary silence. Dean liked this almost as much as the sex. Just sitting, tangled together, was nice.

Cas reached out with a shaky hand. His coat flew from the torn pile on the floor to his open palm. He laid it in the floor beside them and dug around in it. Dean watched him take out the wallet and a smile came over his face. Cas flipped it open and looked at the card again, his deep blue eyes tracing every inch of the small piece of plastic. Dean rested his head against Cas's, softly stroking his bare back.

"You like it?" he asked.

"Yes," Cas answered, "it states that I'm a Winchester, right?"

Dean smiled. "yeah."

"Do...do you think Sam will approve?"

"Sam's the one who made it," Dean said, "I'm pretty sure he does."

Cas slowly sat up in Dean's lap, running his fingertips over the gold print on the card. Dean was glad he was finally able to give something that showed his affection. It may have been a small gesture, but he knew it would mean a lot to Cas.

"I promise to use it always," Cas said, looking up at Dean, "and treat it with the respect it deserves. I won't let it get tarnished or mistreated. I'll keep it the way it's always been, to the best of my ability."

"It's just a card, Cas," Dean scuffed at Cas's dramatics, "I can get you a new one if -"

"I don't mean the card, Dean," he interrupted, "I'm talking about your name."

Dean gulped, feeling another wave of emotion wash over him. He tightened his arms around Cas's back, making him lean closer. Dean stared into the blue pools of the angel's eyes, almost able to see in happy future staring back at him. He took a small breath to speak.

"It's our name, now."

(Author's Note: Ahhh. I just love happy feels. :) So, this is supposed to be the very last chapter, but I'll let you in on a little secret...I feel like I can do a whole new part; one similar to part two, in which they just had sex for an entire day. Back to back smut. There are somethings I still haven't done/still want to do with the boys:

1) more bottom!Dean

2) more panties, maybe some see-through lace

3) Sex in a well-known place such as the queen's bed at Buckingham palace or in the grand canyon

4) A reason for them to actually use the safeword

5) Tie ups

6) Cas constantly flashing his ID card to everyone

So, if you've stuck around long enough for me to get out all the fluff, then I feel you deserve more smut. :) I'll try to fit all of it into part six. It's called Strong Words, and is up on my page.)
