By the following day, Dean's threat of revenge is still present at the back of Castiel's mind, but has dulled in the midst of Deans seemingly innocent mood.
Cas has always been so naïve, truthfully he should have known better by now. Especially when it comes to Dean.
In any case, angel has already lived through one traumatic tickling experience with the brothers when they decided they wanted to teach the him what tickling was firsthand. And one interaction was far more than sufficient in his opinion.
'Why in Father's name would such a torturous weakness be created? In angels as well, no less?' He thinks to himself in amusement.
Castiel is an angel, 'I can handle two humans' he thinks to himself confidently. Trying to ignore the fact that these "two humans" are the Winchesters. The most feared two humans in the universe; in heaven, hell, purgatory and earth.
Cas's false sense of security is short lived as he walks into a bedroom to retrieve something only to be grabbed from behind and shoved onto the bed. He falls forward with a startled yelp.
Before he can even think to teleport himself as far away from their devious plan as possible, Dean appears and wins the struggle to cuff his arms to the bedposts. Barley clicking them in place by the time the confused angel gathers his bearings.
Even before they tell him, Cas can tell the chains are enchanted, engraved, and doused in holy oil. He can feel his energy dampen to a dull throb inside his chest. The feeling amplifies his growing hopelessness as the situation sinks in. This is exactly what he feared.
"Dean, I apologize for partaking in something that gives you the apparent need for revenge, but I was just an accomplice. If my social skills are truly getting better, then my assumption that you would want to get back at Sam more than me would be correct?" Cas states matter of factly, but his usual raspy voice is squeaking slightly. Betraying his frayed nerves.
"Already got me." Sam responds with a wink. "Yeah I got him real good, I thought he was going to pee." Dean adds on with a chuckle, earning an annoyed glance from his brother. "It's your turn now feather face." Dean continues, his eyes trailing down the angels now-helpless body.
If Cas didn't know better -or DID know better- he would think Dean is checking him out. But the thought is banished from his mind before he can fully process it when Dean's hands dig into his ribs.
Castiel is able to control himself at first, through a mix of thrashing and grunting and squinting his eyes. But then Sam joins in on his knees and feet and it's all over.
"No-hohoho. Sahahaham Dehehehehean thihihs i-is unnecessahahahary!" Castiel mumbles through his laughter, trying to bury his face in his shoulder to hide it. However, Dean just tickles the now-exposed side of his neck and forcefully coaxes Cas' head back out to serenade the group with his ironically angelic laughter.
"Of course it's necessary!" Dean exclaims adamantly, as if it's astonishing for Cas not to already understand. "I have to get back at you for helping Sammy attack me."
"IM SOHOHORYYY DEAHAHAHAN! I HAHATE BEING TICKELEHEHED! PLEASEEEE!" Cas keeps tugging and flailing to no avail, all while mentally cursing his father for the existence of this weakness.
Sam, as if on the same thought process, "I still can't wrap my head around the fact that angles are ticklish." He chuckles as he grabs hold of Cas's ankle to begin a target attack on his soles. "ONLY SOHOHOME OF THEHEHEM!" Cas corrects, before his laughter jumps another octave.
"Well you're definitely one of them." Sam responds cheekily. "And a good thing too, I needed to be able to give you a taste of your own medicine for helping Sam do that to me earlier." Dean adds on, moving his wiggling fingers up to Cas's side ribs to earn a rather adorable squeal.
"For the last time Dean, we did it to HELP you." Sam groans, shooting his brother an exasperated glance. "Hell, you THANKED us!" He continues, his scribbling fingers never ceasing as he does.
"Unless you want me to get you again, Sammy, I suggest you focus your energy on tickling." Dean warns, raising his eyebrows threateningly. Sam obliges instantly, all fight immediately gone from his eyes.
"NOOOOO, OH FAHAHATHER PLEAHAHAHASE!" Cas pleads for relief, shaking his head back and forth as tears stream down his face. It's been centuries since he's laughed like this. Heavens, likely even longer.
It almost feels ... nice?

"Look at that, an angel begging for mercy from two humans." Sam laughs, his momentary frustration forgotten.
"He's literally crying for his daddy." Dean agrees, giggling as well. Neither of them still their scribbling fingers as they tease their friend. Enjoying the sight of driving their usually-stoic friend into hysterics.
"PLEASEEEEEE I SHOULDN'T BE LAUGHING LIKE THIHIHIHIHIS! ITS UNDIGNIFIED!" Cas begs after another minute of relentless torture, clearly still trying to grasp the full concept of the situation. Oh well, Sam and Dean are more than happy to remind him of the semantics of being tickled.
Then without a word, the two brothers both amp up their assaults. Sam starts scribbling under the angle's toes, pulling them back to vulneralize them. Switching from one foot to the other to keep the angel guessing.
And Dean pulls up the dress shirt and starts slowly easing his fingers up and down Cas' bare torso. Only to shove them into his armpits and scribble all around them a moment later.
Cas can only scream in reaction, shattering the glass vase next to the bed. He is frantic, screaming in Echonian as he pulls on his restraints. Uselessly kicking his legs to try to do something, anything, to get away.
His usual calm and collected self is in chaos, due to nothing more than some holy oil and two humans.
Meanwhile, Dean is having the time of his life. Not only is he getting his revenge and regaining his wounded pride, he has a excuse to touch the angel. Under his shirt. All over his chest. While Cas thrashes beneath him.
'Jesus why couldn't I just be a chick guy?' He thinks to himself in grudging amusement.
Sam is simply enjoying the fact his brother is happy, Cas is actually laughing, and Sam isn't the one having the living hell tickled out of him. Again.
"NAHAHA PLEAHAHAHSE!" Castiel, a warrior of the lord, has now been reduced to a laughing pile of pudding. Squirming and giggling and squeaking as their onslaught continues.
It almost feels as though they should turn away from the sight, it's strange to see how human and giggly the angel is. Seems like something they aren't suppose witness.
However, no one turns away. This is a once in a lifetime - Or two or three lifetimes, experience. And hell, the angel needs to laugh every so often too! Castiel can only incoherently beg until they have their fun.

Deciding twenty minutes is enough torture for him, the two brothers cease their tickling with mirroring grins.
"Thank you." Cas pants, "Thank you." He says again through his gasping breaths. Grateful the torture is over - For now.
Chuckling, the two brothers undo the cuffs and released the breathless angel. Throwing a few more teasing comments in as they do so, of course.
Then, without so much as a sarcastic comment in return, Cas immediately teleports himself away to keep from the embarrassment - And to recollect himself to his usual standard before conversing with the brothers.
That is likely his safest option.
His wings flap as he gains altitude, not stopping until he is level with the clouds. "Never underestimate a Winchester. To think I haven't learned that by now." Cas mumbles to himself, a genuine smile on his lips as he vanishes into the afternoon sky.
