One shots - Destiel

Well that was a turn of events...

Idek guys I'm just making this one up as I go along, set in season 10 :)

"Dean, I think I've found it, I think I've found the cure." Cas announced as he suddenly appeared in the bunker. Dean walked over to Cas, maybe a little too enthusiastically as he whacked his leg on the table.
He winced in pain, but tried not to show it.
"So, what is it then?" He asked the angel.
"Well... You might not like it..."
Dean nodded at him, urging him to go on.
"Well, what you need is; the first blade, the blood of a demon, the blood of an angel and..." He trailed off.
"Yeah, and what?"
"Well.. The, uh kiss of an angel.."
(Wiggles eyebrows)
"Oh.. Okay I, uh, I guess so." The hunter said awkwardly scratching his neck.
"So, uh, let's get this show on the road!" He said, clapping his hands together.
"Right, I need you to do the first part, you need to cut off the mark, or at least cut it open, using the first blade, this is probably the hardest part. I can sort out the rest for you." Dean nodded, he knew how difficult it would be for him to control himself, he could barely be anywhere near the blade without having the urge to kill anything and anyone in his way, let alone use it. But he also knew that he had to get rid of the curse, for his family's sake.
Cas disappeared for a few seconds before returning with the blade in his hand, he gingerly passed it to Dean, nervous about what could happen.
As soon as Dean's fingertips met the handle, he felt the power surging through his veins. He took a deep breath and closed his eyes to calm himself down. He took the blade to the mark that clung to his skin and sliced it open, before throwing the blade across the room, he couldn't stand the sight of it.
"Okay, this is the part where I intervene. I need to pour this demon blood into the open wound." He got out a small glass tube that had the blood in it and tipped it into the cut on Dean's arm, while chanting something, almost inaudibly, in Latin. Next, the angel took a vile of more blood, but this time it was an angels, most likely Cas', and poured it into the wound while chanting something that, this time, sounded like it was in Enochian.
The hunter hissed in pain as the two types of blood mixed together, bubbling slightly.
"Now, um, now is the part where I.. I have to kiss you." Cas said awkwardly, turning slightly pink, which made him look even more adorable than usual.
"Well, what are we waiting for then?" Dean said quietly to Cas as he walked closer to him. He saw the angel gulp as his bright blue eyes flickered upwards to meet Dean's forest green ones. Dean put his hand around the back of Cas' neck to bring him closer to him for a gentle kiss. To his surprise, when Dean pulled away, Cas grabbed onto his collar and gave him a much more passionate, heated kiss. Cas's hands traveled up Dean's back as he pulled off his tee shirt. He grabbed his hand and dragged him up to Dean's room, where he threw him down on the bed.
Cas POV
Honestly, I'm surprised as to where all of this sudden courage has come from, its probably because of the amount of times I've imagined this moment... I look at Dean and realise that although he's shirtless, I still actually have all of my clothes on. I tear off my clothes as quickly as I can, until I'm stripped down to my underwear, and although they're not exactly the most flattering undergarments, my vessel still looks pretty good in them. I crawl onto the bed and straddle Dean. Oh how long I have waited for this day. I bend down to kiss his soft lips, as soon as they connect I see fireworks and I get butterflies in my stomach. I kiss down his neck and his chest, tugging at his skin slightly with my teeth, being sure to leave little red marks behind. I pull off his jeans agonisingly slowly.
"Caaaas." He complained. I just smirked and looked up at him through my eyelashes. When I had finally thrown his jeans to the floor, I kissed up his muscular thighs, leaving as many hickeys as I could. Then I got to his black boxers and started to pull them down by putting the thin fabric between my teeth...
