As Dean approached Castiel's room, his mind was a whirlwind of crazy thoughts, what was he doing? Did Cas feel the same? Should he even attempt it? What if Cas rejected him? Before he knew it, he was stood at Castiel's door, staring at it with his hand subconsciously resting against the door handle.
Castiel was laying on top of his covers, staring at the ceiling, remembering the look on Dean's face as he followed that water droplet right down to his boxers, a smile still visible on Cas' face, cold air caressing his skin, causing goose bumps to appear, but he wasn't cold, a strange warmth had spread through him when he was sat in the library. Dean's emerald green eyes and sheepish smile were all Castiel could see when he closed his eyes. He was marvelling at the memory of Dean's reaction to the moans escaping his mouth earlier when he was interrupted by a creak from outside the door, he sat bolt upright instinctively.
Dean cursed under his breath as he shifted his weight outside Castiel's door, invoking a creak from the floorboards, 'Oh crap' Dean muttered as he rolled his eyes, he heard Cas move on the other side of the door and before he knew it the door handle was turning in his hands, except he wasn't the one turning it. He was frozen, like a rabbit in headlights, he was confronted by those dazzling blue eyes and he leaned towards Cas and kissed him, before he could talk himself out of it. Castiel was taken by surprise, he was shocked at first and he could feel Dean pulling away in disappointment, Cas let go of the door letting it swing open fully before he put his hand at the back of Dean's head pulling him closer and returning his kisses, matching his rhythm. Dean seemed to relax at that gesture and his hands went to Cas' waist, he moaned a little, as though he was letting go of a bucket load of stress and anticipation. His reaction caused a smile to tug at the corner of Cas' lips, and Dean must've felt it because he smiled too.
Dean's heart was pounding in his chest, was this really happening? He had been fantasising about this moment for so long, he never realised that Cas had felt the same. His hands gripped tighter at Cas' waist and what had started as gentle, unsure kisses, soon turned into hard, lustful kisses. A small moan escaped Cas' lips as Dean held his waist tighter, and Dean smiled pressing his lips into Cas'. They moved instinctively backwards, it was like a force greater than themselves was pulling them to Castiel's bed. Dean stopped kissing Cas, mainly to take a break, regain his breath and think about what the hell was happening. Cas brought his other hand up from Dean's hip and placed it on his cheek, slowly tracing Dean's cheekbone with his thumb as Dean nuzzled into the palm of his hand. 'Do you even understand how long I have been waiting for this?' Castiel asked, his voice quiet, gentle, and his all to familiar, head cocked to one side, quizzical expression, his eyes locked on Dean's, a smile tugging a the corner of his mouth.
'You have been waiting for this? My god' Dean looked up and rolled his eyes, 'Why didn't you tell me, I've been driving myself insane waiting for this, wondering if you felt the same.' Dean was taken aback by how snappy that came out, he was hurt a little when he registered the look of pain in Cas' eyes, 'I'm sorry, I didn't mean for it to-' he was cut off by Cas' lips crashing against his again, he pushed Cas down gently on to his bed and pulled away 'Rude' he smirked at Castiel, before tracing a line of kisses from his collar bone to his ear lobe, a murmur escaped Cas' lips as Dean located a sensitive spot just below his right ear lobe, he smiled to himself as he propped his weight onto one elbow, his hand tracing the lines carved into Castiel's body by his muscles, every so often stealing a glance at those bright blue eyes filled with lust and want. They remained like this for a while, neither of the speaking, just gently caressing the other, taking in every aspect, every dimple, every scar, just memorising and exploring. The was the occasional kiss shared, but mainly just lying together, eventually, Dean laid on his back and Castiel curled into his side, his head on Dean's chest as Dean fought with the covers and draped them over Cas and himself. 'Goodnight Dean' Cas mumbled into Dean's chest. 'Night Cas' Dean replied, planting a kiss on Cas' head.
Dean woke from the harsh sunlight blanketing him and panicked a little, this wasn't his room, he was in Cas' room, and, holy crap, it wasn't a dream? He felt the warmth of Cas curled into the side of his body, the weight of his head on his chest, and his heart stopped as Cas stirred, opening his eyes and looking up at Dean. 'Good morning' Cas said, cool as a cucumber. The first thing that struck Dean was how adorable Cas looked first thing, his hair was a shaggy mess and his stubble created a faint shadow over his face, and as always, his eyes sparkled, though this morning, Dean noticed something different for the first time, Cas was looking up at him, his eyes filled with a heart-warming glow. Dean planted a kiss on Cas' nose and ran his hand up and down his spine, smiling at each shiver he caused Castiel.
