Intentionally Dean avoided making eye contact with Castiel. It wouldn't do to blush in front of Sammy. Once concise step back and Castiel placed himself exactly the required distance away.
"I am here to inform you that I have discovered a summoning spell," Castiel spoke easily, unaffected by Dean's insistence.
Hope is infectious. Slowly hope settled in Sam and Dean's hearts. It only took moments for all three men to be huddled around the small table. Their only illumination was Dean's consistently emitting glow. Sam's laptop sat in sleep mode on the chair, making more room for the open books. Laid out neatly was a list of ingredients, a drawing of a symbol, and a few lines in Enocian. With his audience so close Castiel didn't need to project his voice any, instead he murmured, "It only works on a Blue Eye. You should try to summon me tonight to test the spell."
Sam read the ingredients: Salt, candles, summoner's blood, crushed mammal bones, and sanctified water. "Okay so how do we get mammal bones and sanctified water?" Sam asked, his mind already forming possibilities.
"As I went to urinate earlier I passed owl droppings. There should be rodent bones inside. For the water I must first make myself pure and then I can sanctify it myself."
Listening to Cas talk, Dean was able to tell something was off, "What do you mean 'make yourself pure'?"
"I must repent for my sins and-"
"Your sins? What sins? You're fucking perfect," Dean argued back.
When a Green Eye is upset their power manifests as coiled heat. Dean learns that when a Blue Eye is upset their power lights the room in purity, highlighting your every weakness, as something terrifying close to black wings manifest from their backs.
"My sins," Castiel finds Deans eyes. Pure crystal blue cause Dean to stop breathing, "Have been for you. It was you Dean that planted doubt in my mind." The way Castiel says his name makes Dean's knees go weak. "It was you that opened the door to questions. It was you that had to be exactly what I never needed. And I must repent for all the sins that have happened. And all the sin I wish to happen. I must purify myself tonight, Dean."
Eternity crammed into moments enclosed the two. Castiel took one step forward as he invaded Dean's privacy again before flashing away entirely. Going from Heaven's Light to pitch black disoriented both Winchesters. Dean stumbled forward. Loosing Cas somehow caused him to loose his balance. Fortunately Sam was unable to see this. In the darkness Dean composes himself, fully aware that Sam bore witness to everything. It's when Dean is reaching for their kerosene lamp that he realizes his arms are shaking. The priest's words are swarming his mind and he needs to get away.
Finally Dean focuses enough to create a small flame in his hand and finish setting up the lamp for Sammy. "I guess we should get the rest of this spell ready. Sammy why don't you draw out the symbol and practice the Enocian. I'll collect the bones."
Not waiting for a reply Dean snatched their napkins from dinner and a bottle of water before bolting out the door. It didn't matter if he had no idea where to go, he just need out.
'And all that I wish to happen' Echoes in his mind. What does Cas with to happen, with Dean, that's sinful? The mere possibilities caused a tingle to begin in his chest. Cas's voice as he says Dean's name competes for a chance to drive the man insane. Castiel's deep voice made even heavier with meaning. Only one word, and Dean feels incapacitated by it. Concepts he hadn't dared to dream tease at his mind.
The forest provides the cover Dean's desperate for. Away from his brother, away from prying eyes, and surrounded by the safety of night. He leans against a nearby tree trunk, and slides down onto the ground. A dangerous mixture of fear and excitement cause an inexplicable reaction in him. Thoughts of Castiel, eyes ablaze with power, and thinking sinful things.
Dean groans slightly and bites his lip. He's not alone out here, Castiel is lurking about. Too much noise and he'd draw an unwatned visitor. More forcefully than needed Dean slams his head against the soild bark behind him. The shock of pain cooled the blaze in his chest.
Where had that reaction come from?
How did thinking of Castiel develop into this? The guy's a dork. And... well a Guy. How's thoughts of a guy making Dean's heart skip a beat?
Not matter how scary the questions, right now he can't bring himself to care about the answer. Piercing eyes and a soft smile is all Dean needs to bring his hand down over the small tent in his jeans. His mind will rationalize this later, for now nobody needs to know. Memories surface and feed into Dean's excitement.
Dean reclining on his bed in the school, and Castiel standing over him. Something dangerous in the priest's smile.
Castiel as he throws open the doors to the school, highlighted by lightening. A handsome face, and serious expression.
Watching Castiel as he works the action on Dean's shotgun. His hands strong and sure.
The look of fierce determination as Castiel fights to save Sam's life.
Castiel's saying his name in that deep voice. 'Dean'
Oh fuck. What would Castiel do? Would he be aggressive? Dean began to imagine what could happen between them, tried to imagine exactly how it would feel.
Maybe Castiel would shove Dean up against a wall. Or the Impala. God that's it, Dean backed up against baby with Castiel crowding him like always. The priest's hands fisted in Dean's shirt. Dean would struggle of course, 'cuz he can't give it up entirely, and Castiel would push him harder.
Now Dean was palming himself shamelessly through the denim while looking up. Imagining the pressure of the tree against his back was actually his car.
Castiel will look at him with those god damned eyes, and what would Dean see? Would there be passion in all the blue? Would there be something fierce? Does it matter? Because then Cas's lips would be on his.
The not moaning policy is not going to work. Thoughts of Castiel's lips on his, while they are pressed tightly together is causing pained noises to escape him. Eagerly Dean undoes the fly on his jeans and pulls himself free. What was once a budding arousal is now a full fledged erection.
Castiel would taste like what? Like perfection. Like addiction. And fuck what he tastes like, when they start to grind together nothing else compares. Dean would seize Castiel's ass and remove all the space between them. Castiel's hands would move from his chest to Dean's neck.
Dean's hand moved faster and fuck he wasn't going to last long.
Would Cas moan? What would that sound like with his voice so deep and fuck would Dean feel that moan against his chest? Castiel would try to touch Dean. Pull his shirt up and run those rough strong hands along Dean's stomach and side. Castiel is eager because god he wants to do sinful things with Dean.
That's it, one final pump along his shaft and Dean was cumming hard. Fortunately Cas's name was not on his lips, but a wordless moan was.
