Silvaxus - you asked for trenchcoat, and I wrote half of this and then forgot all about it. Apologies! Hope you didn't lose all hope.

"Cas, you can't wear a skirt on a hunt. It's impractical!"
"I am a celestial being, practicality means little to me."
Dean threw up his hands in defeat, leaving the angel to continue admiring his reflection clad in nothing but his trench coat and skirt. They were about to head out after a shifter, and Cas didn't want to take off the impractical outfit.
"We've created a monster."
"Worth it though Sammy."
"I can hear you both, you know."
Dean stuck his tongue out immaturely at the closed door, finished brushing his teeth and spat into the sink. Sam was done a minute later, kissed him quickly and they both headed out to find Cas no more ready than they had left him.
"Cas, seriously. Take off the skirt."
The fabric vanished before their eyes and left Cas naked save for the open coat. Dean felt his mouth go dry, but they really needed to get off on the hunt.
"Ok, now put your normal clothes on before this shifter eats someone or something."
Cas 'popped' his suit back on, face showing some petulant annoyance but they had work to do damnit. If Dean could learn to wait, so could Cas.
The hunt was exhausting but productive - the shifter had a friend, and now both of them were quite assuredly dead. None of them had the energy to do more than collapse into bed that night in their motel, and Dean had almost forgotten about the trench coat thing by the next morning. Cas popped in with bacon and eggs in to-go boxes for their breakfast, and Dean ran out to buy more coffee and gas his baby up before they moved on the next day.
Whistling as he carried the bag containing beer, potato chips, beef jerky and lube into the motel room, car keys spinning around his finger to accompany his surprisingly good mood, Dean let himself in and placed the bag on the kitchen table. He pulled the lube out to move to their travel-sex-bag, then turned around and promptly dropped it.
"This was Sam's idea."
Cas was laid out on the bed, wearing nothing but his trench coat and his newest pair of skimpy underwear in crimson - Sam's favourite colour on either of them other than the usual green or blue.
"Uhhh... yeah. Good idea."
It waa juvenile and yet unbelievably hot to see, some image in Dean's head where Cas would wear nothing but the coat and whip it open to reveal that slim, pale but still sexy body he had squirreled away under it. Dreams did come true it seemed.
"Told ya he liked it. I think Dean has a thing about being flashed by an angel."
"Flashed? I'm not flashing anything."
"It's a phrase Cas. Flashing the goods, meaning revealing your naked self."
"Oh."
Dean wasn't really paying attention to them talking, reaching for the tie on the trench coat. Cas looked confused as Dean pulled it out, sliding it free of the loops until it was all in his hands. Turning to Sam as an idea formed, he asked.
"Where's his tie?"
"Uh, here."
"Hold that a sec. Cas, hands."
Cas held his hands out obligingly, letting Dean use his coat tie to tie them together.
"Yeah, yeah, you can break it or zap it but I can pretend."
Still confused, but getting into it judging by the erection Dean felt pressing into the back of his thighn Cas let him push his arms up over his head still bound, then tie the navy suit tie around his face like a blindfold.
"All trussed up and pretty. Now we can have some fun."
He could see Cas' serious eyebrows, creasing in the middle as Dean leant down to kiss him before moving away to strip himself. Sam took off his shirt, unzipped his jeans but stepped back and pulled up a chair, letting Dean have his moment. They hadn't really ventured into this territory before, because being tied up usually meant near death and no sight meant danger... but Cas was less concerned, knew he could angel mojo his way out of almost anything. And trusted Sam and Dean implicitly.
"I understand. One sense deprived raises other ones."
"That's it Cas. Now hush, let me play."
Down to his boxers, Dean retrieved the lube from the floor of the kitchen area before kneeling on the bed next to Cas. The trench coat was like gift wrapping, Cas exposed like Dean was unwrapping him on Christmas day. The angel on the tree... angel in his bed. Close enough.
Cas whined when Dean pinched a nipple, unable to tell exactly what was happening until hands were on him. Moving to tweak the other, he felt his own cock harden as Cas wriggled. They should have tried blindfolds before... this was awesome.
"Don't worry Cas, gonna fuck you good."
By the time Dean finally touched the angels erection, it was hard as nails and sticky with precum. Giving him a quick squeeze, Dean teased him a little more.
"That's just so bad for the fabric."
He whipped the messy fabric down slender, muscled thighs until they were completely off, leaving Cas bare save for his gift wrap and binds. He was sturdier than them, and should be used to getting fucked good and proper by now but Dean loved this part, teasing him open until he begged to be filled.
"Don't you think he's been teased enough Dean?"
Cas made agreeing sounds with Sam, pushing back on the fingers in his ass and squeezing around them to try and tempt Dean to get a move on.
"You getting in on this little bro?"
"Not Cas... he's for you. Fancy a new position?"
He caught on quick, bending at the waist to let Sam slip fingers between his cheeks and aroused enough to not care about the stretch and burn of a hurried prep. Cas was almost in tears waiting by now, lifting almost clean off the bed from one brush to his cock.
"Hips up, need to raise you a little for this to work."
Cas complied, letting Dean put a couple of cushions under his hips to raise the angel to a better angle. Dumping a handful of lube over his cock, Dean finally buried himself in the angels heavenly body. Sam followed suit, filling Dean perfectly and wrapping arms around him to keep the middle man upright as sensation almost overwhelmed him.
"Uhhh, new favourite I think."
"You say that every time."
Sam's thick, hot cock pressing on his prostate while Cas squeezed and massaged his cock with his inner muscles...
Dean was in heaven.
"C'mon Sam, you gotta lead here."
"Thought you would never ask. Let us know if it's not working for you Cas."
Sam's first thrust knocked the wind clean out of Dean, perfect aim and powerful stretch as he pushed Dean into Cas, who was near mindless with arousal by this point as he took the impact of two built, heavy guys who knew how to fuck.
"Again."
He begged, feeling Sam pull back and use his grip on Dean's chest to slide him out of Cas too until just his tip remained. His punishing thrust drove them both forward again and Dean forgot how to breathe as unimaginable pleasure washed through every fibre of his body.
"Yep. Definitely new favourite."
Those were the last words Dean managed to speak, every other sound some kind of desperate, pleasured wail as Sam fucked them both - he might be using Dean as a proxy, but he was fucking Cas just as much with his hard, feral thrusts.
"So close, so close."
Cas whined beneath him, the angels cock swollen and purple against his lean stomach as he was pushed into again and again with the sheer force Sam sent rolling through all of them. Cas was still bound and blindfolded, back arching up so much it looked painful until the invisible strings holding him up snapped, climax overtaking him. Cas came and came and came, making a total mess of himself, his coat, the bedsheets as he spilled and cried out like he was in agony beneath the erotic torture.
Muscles squeezed tight around Dean, three more slamming thrusts from Sam and he was gone too, nails scrabbling over Cas' lean hips and drawing blood as his back bowed, cock twitched and he came with a keening cry. Sam had been holding back, grunting and biting down on Dean's muscled shoulder as he spilled hot and copiously thick inside him. Sweaty and sticky and hopelessly exhausted before midday, the three managed to pull out from each other before falling on the sticky, messy bed.
"I think we ruined his coat."

Ugh this is short and feels disappointing but it's all I could seem to force out of my brain on trench coat Wincestiel sexing.
