⚠ Wing kink, grooming, oil ⚠

-Cas's POV-

Ever since I fell from heaven, I haven't been able to groom my wings. I'd been able to deal with it, though, as they were fairly large and not much was stuck in them. Besides, flying would get a lot of the debris out.
But they're starting to hurt now. Hurt and itch, so badly that it's beginning to get hard to hide from Sam and Dean.

Sometimes, when one of my wings twitches, it makes the pain so much worse. At this point, it makes me want to cry. That's how bad it hurts.

To put this into perspective, imagine walking on a severely sprained ankle with no ace wrap or painkillers.

Now you may be wondering, Well Cas, if it hurts so bad, why don't you just ask someone for help?
To put it simply, my wings create immense pleasure when they're touched by anyone who is not a celestial being.

"Cas? You okay?" I hear Sam ask. Right. We're currently in a hotel room, relaxing after the mission we'd gone on. Just another ghost hunt, nothing new.
"I'm fine." I responded simply. It was a lie, but I'm not going to say that. "You don't look fine.." he pressed, giving his signature concerned frown.

I was about to respond, my wings fluttered out of instinct to try and clean themselves. Which created sharp pains throughout them.

-Dean's POV-

I looked up when Sam started asking Cas if he was alright. I agree with him; he's been acting off for a while.

Then, out of nowhere, Cas gets this extremely pained expression and actually fucking whimpers, pulling at his shoulders like that was where the pain was coming from.
"Cas, what the hell?!" I ask, a little panicked. And worried, fine. I'm worried about him.

"Mm-mm-mm, someone's been neglecting their hygiene." a voice says. I look towards it to find Gabriel the ass angel, sucking on a lollipop.
Before Sam or I could even say anything, he walked up to Cas, ticking. "No wonder you're almost in tears, little bro, they look awful. How long's it been since you've-?"

"One and a half years.." Cas said in a strained voice, crying a bit. I was confused as hell, looking at Sam. He looked back at me and shrugged.

"For fuck sake, Castiel, you can't do that! They need groomed weekly!" Gabriel says, plucking something invisible from Cas's back and flicking it. Cas sighed in what I could only describe as mild relief.
"Well, your options are me or Dean." he says, crossing his arms. Sam spoke up before I could. "Wait why just Dean? Why can't I do whatever he needs help with?" he asks.

Gabriel looks at him. "Sammy, let's go have a talk, okay? Cas, tell Dean." he says, leading Sam out by the shoulder and closing the door.

After a moment of staring at the door, confused as hell, I look back at Cas. "What the hell is going on?" I ask him, crossing my arms. Cas looked at me and sighs in defeat.
"My wings.. There's dust, debris, and kinked feathers stuck in them and it causes pain... That's why, like Gabriel said, angels usually groom weekly..." he tells me.

-Third Person POV-

Dean stares at him for a moment. "Well why in the hell didn't you tell me? I could have done it- granted I don't know how, but you can't just suffer silently, dude." he says.
Cas looked away, blushing a little. "I couldn't ask you to do that because of the affect it would have on me." Dean looked confused by this.

"What do you mean?" he asks. "Will you run away if I tell you?" Cas retorted, deadpanning him. Dean gave him a bewildered look. "No. Just tell me, man." he says.
"Fine. If a human such as yourself were to groom my wings, it would create immense pleasure and cause my oil glands to leak." Cas said simply, making Dean turn bright red.

"Wait- you're saying if I touch your wings, you get horny?" he asks for clarification. "I suppose you could say that, though if they're stimulated right and for long enough, it could cause an orgasm." Cas mumbles, looking down at his hands and fidgeting with them.

Dean's mouth falls open slightly in shock, completely gobsmacked and speechless. After a long moment, he clears his throat. "I uh- I'd still be willing to help. I- that is, if you'd want me to." he says. Cas looks at him. "You're aware this will arouse me, greatly, right?"
Dean let out a breathy laugh through his nose. "Well, yeah, I got that. I'll help with that afterwards if you still need me to."

"You- would really be willing to engage in such an intimate-" Cas starts. Dean held up a finger. "I'd fuck you, alright? Yes. Now are you going to let me groom your wings or not?" he asks.
Cas blushes but nods. "I suppose there's no harm.. But we will have to go outside, preferably somewhere desolate." he says.

"Well, if you can manage one flight, try somewhere in the country." Dean says. Cas nods a little, putting a hand on Dean's shoulder and flying them to a desolate spot out in a field.

"Okay.. Just.. Don't make fun of them.." he mumbles, sitting down in the grass. A moment later, he revealed his wings to Dean's plane of sight; they were black, and fairly large.
"Woah.. Even beaten up like this, they look amazing, Cas-" Dean says. "Right, where should I start then?" he asks a moment later.

Cas blushed a little. "Start with the debris."

-Cas's POV-

I was nervous, but if Dean says he's okay with it, I am too.

He started taking out the debris stuck in my wings, which didn't feel like much of anything except relief at the moment, as most bits were sticking out.

He continued doing this for a while. "I think that's it for the junk, so.. Now what?" he asks me. "Feathers. Pull out the kinked ones and b-brush through my wings to make any lose ones fall." I tell him. This is where it gets more intimate.

"Pull them out? Won't that hurt?" he asks, frowning a little. "Mildly, like plucking a single strand of your hair. But I can handle it." I say, smiling reassuringly.
Dean nods a little, and his hands are on my wings. He pulled out the kinked feathers first, to which I'd occasionally wince or hiss.

But when he started carding his hands through my feathers, I swear it was the best feeling in the galaxy.

-Dean's POV-

Cas seemed to be enjoying this. A lot. The slightest touches were already making his breathing rate change, but when I started brushing though the wings, man did he get vocal.
I don't even think he knew he was doing it. But damn, I had to admit it was hot. All the small moans and noises spilling from his mouth; I might get hard from this, too.

I noticed something as I was grooming him, too- the closer I got to the base of his wings, the louder he would moan. There must be like a G-spot there somewhere.. Man, if I find it-

Then I notice something else: his feathers were wet, specifically the ones in the front by the base. He did say something about an oil glands, right?
Curiously, I follow the wet trail, eventually finding a small, wet bump which I assume was the gland.

But what really caught my attention was the way Cas squeaked and moaned when I touched it. Ah, so that's the G-spot huh? I run my thumb over it again, testing that theory. Sure enough, Cas let out another moan, balling his fists together.
"Damn, angel G-spot huh?" I say, smirking a little. "Dean-" Cas says gruffly, blushing a bit. "What? Gettin' a little worked up over there?" I say, just to tease him at this point.

"Oh, you are so going to regret this."
