Summary: Dean shares a few of his favorite kinks with Castiel for the first time.
Notes: Written during my 12 Ficlets in 12 Days in 2020-21 project project for cheeseontoast1.

Sometimes you had to take matters into your own hands when you were in a relationship with an honest-to-goodness angel. It wasn't that Castiel was bad in bed, because he definitely wasn't. And it wasn't because he was inexperienced, because Dean often found Cas' curiosity and excitement to try out new things charming. No, it was more the fact that Castiel preferred to make love, and Dean had no problem with that... but sometimes Dean just wanted to be fucked.

There were times Dean wanted it hard and kinky and relentless, and that wasn't Castiel's nature. Cas honored. Cas healed. Cas worshipped. Cas cared. Cas didn't understand that sometimes it felt good to be uncomfortable, to push boundaries, to be mischievous.

“How's your pie?”

“Mmm.” Dean nodded approvingly. The diner's cherry pie was one part delicious and one part ironic. “It's great.” Cas knew the way to his heart was through his stomach, but Dean's heart wasn't the body part he was concerned with right now.

“As I understand it, those are high-altitude cherries, grown in Wenatchee, Washington at an elevation of 2,600 feet above sea level. That is literally half a mile towards the moon.”

“You don't say?” Dean tried to sound interested in the facts Castiel was sharing, but he was anything but. His mind was on another matter entirely.

“And the pie crust is made from great river organic whole wheat bread flour, milled from Red Spring Wheat in the Northern Plains.”

“Uh-huh. That's nice, Cas.” Dean took another bite. He really did like the pie, and on any other day, it would have given him all the pleasure he needed.

Quiet fell between them, apart from a few clinks of metal fork against ceramic plate and the ambient noise of the diner's busy kitchen. 

It was Castiel who broke the silence between them with a question. “Dean, is something wrong?”

“Hmm? No, I'm fine.” He kept his gaze trained on the pie, however, and he probably didn't sound the least bit convincing .

“But you don’t seem fine. You seem distracted. And your cheeks are slightly flushed. Also, you keep shifting around in your seat. Are you in some physical distress? Were you injured and failed to tell me again? I know you made me promise to not use any of my—” at this, Cas held up his hands and mimed quotation marks in the air during the next three words “—angel mumbo jumbo on you without your permission, so I will refrain from doing so. But I am concerned about you.”

Dean hadn't meant to concern him. Hell, he hadn't meant for Cas to even find out. Some kinks were private and it was better they stay that way. But he also couldn't let Cas think he had been injured. “I'm just... distracted because I'm playing with something.”

“Right now?”

Dean nodded.

“I don’t see it.”

Dean stabbed at his pie, scooping up another forkful of cherries, flaky crust, and whipped cream topping. “Well, that's because it's concealed in a private place.”

Castiel looked more confused, not less, at this explanation. “Is it in your car?”

Dean closed his eyes, letting out a light breath. He glanced around to make sure no members of the wait staff or stray customers were about to walk by. None of the other patrons at the diner were close enough to overhear from their sears, either. “No,” he said, in the softest whisper he could manage. “It's in my pants.”

Cas' eyes went wide, and immediately their gaze dropped down, as if he could see through the table, through the layers of fabric. And perhaps he could. “What is it?”

“It's a toy.”

“Ah. Like LEGO bricks or Barbie dolls?

“No. Nothing like those sort of toys. This toy is made only for adults, and especially for men.”

“I understand.”

“You do?”

Cas shook his head. “No. Will you explain it to me?”

Dean wolfed the down the last few bites and threw some cash on the table to cover the bill and tip. “It's not the sort of thing you'd be interested in.”

To Dean's surprise, Cas looked visibly hurt. “Is it something you like?”

Dean moistened his lips and shifted slightly in his seat. “Very much.” Hell, he loved it.

“Then it’s something I’m interested in. Please elaborate.”

Under no allusions that Castiel would like this once he knew more about it, Dean shrugged on his coat. He wasn't about to have this conversation in the middle of a diner. Sure, his intentions were to have a bit of private play out in public, but no one could see his rock hard dick under the table or under his jacket and jeans. Anyone could potentially overhear if Dean stopped to try to explain about the vibrator and how it made him feel. And even if he did explain, there was no guarantee that Cas would understand how good it felt to tease and torture himself in public. Perhaps it was best not to try. But he did appreciate Cas' interest in him, and didn't want to take that for granted. “Actually, I think it would be easier to show you.” He got up, and Cas raised his hands up at once in a panicked stop gesture. “I wasn't going to drop my jeans here in the middle of this diner and show you now,” Dean stressed. “I meant when we get back to our room at the motel.”

“Oh.” Castiel nodded, seeming relieved but still not enlightened. “You’ll be all right to drive?”

“Sure will be.” He'd driven here with it on just fine. In fact, Dean had driven with this on dozens of times. Sometimes Sam knew and didn't say anything, and sometimes he had no clue. Being behind the wheel and having his dick stimulated at the same time was one of the purest joys Dean Winchester could imagine. It was almost as good as... “Let's make a quick stop on the way back, all right? As long as I'm showing you this, I might as well show you the other thing, too and get all my cards out on the table.” He held up his hand. “And before you ask, no, it’s not like playing cards either.”

Castiel got up and followed Dean out without a word, both curiosity and concern playing in his eyes though his expression remained relatively emotionless as usual.

“You were right,” Castiel said with a frown as he stared down at Dean's crotch. “I don’t think I like it.”

“Heh,” Dean smiled as he lay back on a mound of pillows and ran his hands up and down his thighs in anticipation. “I had a feeling you'd say that.”

Keeping his gaze fixed on the vibrating toy Dean wore, Castiel took a seat on the end of the bed. “It looks like it would be uncomfortable.”

“It is a little... but it also feels fucking amazing, even on the lowest setting like it's on now.”

Cas' eyes went a little wider. “Lowest setting?”

“Uh-huh.” Dean reached down and pressed a tiny button on the side of the vibrator and the quiet buzz got incrementally higher in pitch. “There are twelve different settings. And I feel the vibrations here in the cock ring,” Dean explained, sliding one finger around the black ring affixed snugly around the base of his penis. “And I feel it here.” His finger caressed the curves of the toy, showing where it was vibrating against his perineum. “The vibrations are quick and stimulating, even more intense than if I were stroking it with my hand or thrusting into you.” Dean was pleased to see that it was Castiel's turn to have some pink in his cheeks.

“I see,” Castiel said. “But what about this?” He held up the bottle of cheap cologne they'd bought at a drug store on the way back to the motel. “I understand that scent can trigger all sorts of memories for humans. Is that what this is about?”

“Not exactly.” Dean pressed the other button on the vibrator and let it go back to the gentler level. He didn't want this to be over before the fun even began. “I'm horribly allergic to that cologne.”

Alarmed, Castiel lept to his feet and backed up a few steps until he ran into the wall. “I should get rid of it, then!”

“Don't you dare. I spent hours hustling pool to get the money that paid for that.”

“But... it will...”

“It will make me sneeze,” Dean finished for him, though this answer did not seem to calm Cas any. “That's the whole point. And that's all it'll do. No rash, no itching, no closing windpipe, no trip to the emergency room required. Just a hell of a lot of sneezing.”

“But why would you want to do that to yourself?”

“The same reason I want to do this to myself.” Dean gestured toward the vibrator. “The sensation feels good to me.”

“How can it? It's misery.”

The truth was that a little misery and torture done the right way could be exciting, even arousing. Sometimes it felt good to be helpless and out of control of a situation in bed. Sometimes it felt good to get himself right to the edge and enjoy that desperate, needy urge as long as it lasted before he tipped forward into ultimate, magnified waves of pure pleasure. But how could he explain that to the angel who gripped him tight and raised him from perdition when he was being tortured by demons?

“To know the light, you must know dark.” It sounded like something Sam would say. Or the Dali Lama. Or someone along those lines who was wise and contemplative.

Castiel regarded the cologne bottle. “What would you like me to do with this? Spray you with it?”

When he'd bought it, that was exactly what Dean had had in mind. With a vibrator on his cock and cologne on his neck, he would be at the height of arousal in so many ways. In fact, he might add a butt plug to make the experience complete if he weren't worried about a strong sneezing fit causing it to dislodge. But now that Cas was here before him, wanting to understand, Dean had a better idea of what to do with it. “I want you to go into the bathroom and apply a few drops to three spots on your body. Don't tell me where! I want to discover that part for myself.”

For a moment, it looked like Castiel would refuse to play along. It was against his nature entirely to cause Dean any discomfort.

“Please, Cas?” Dean stroked his hard, leaking cock luxuriously. He did it more for the visual than the sensation, though that wasn't bad, either. “I can do this on my own. I’ve done it dozens of times. But today, I want to share the experience with you. I want the vibrations to get me to the edge, I want you to make me sneeze, and I want both of those things together to make me come.”

Castiel slowly turned the bottle of cologne in his hand, examining it from every angle as if it might have a warning against using it as a sexual aid. Finally, he clutched it to his chest and headed to the bathroom. Dean listened closely, half-expecting to hear the sound of Cas emptying the bottle down the sink. Instead, he heard the sound of the stopper being taken out, of clothes ruffling, and of the bottle being set down on the counter.

When Castiel emerged, there was no visible evidence of where he might have applied the cologne, and Dean was filled with anticipation at the adventure ahead of him. At his core, Dean Winchester was a hunter. “C'mere,” he said, patting the bed beside him. Castiel climbed onto the queen-sized bed and folded his body against Dean's. The scent of cologne was faint but there, Dean was sure this wasn't just wishful thinking. Cas really had put some on.

“Are you certain about this?” Cas added.

“Oh hell yes. In fact... let's raise the stakes. Every time I guess right, I get turn up the vibrations a notch. We'll see if I can guess all three locations before I give into my orgasm.” Given all the playing he'd done since leaving with Cas for the diner, he wasn't sure he'd even make it to one before he came, but he was eager to find out.

Dean started with Cas' neck, as it was exposed and easiest to reach. He nuzzled his face in against the warm, soft skin and took deep sniffs on one side and then the other. When nothing happened, Dean pulled his head back to find Cas smiling knowingly. Oh, so it seemed the angel wasn't above a little mischief of his own today after all.

Loosening Castiel's tie and unbuttoning the top button of his shirt, Dean moved in close again to sniff. Still nothing. Button by button, moved down the angel's chest, sniffing. He was just about to give up when the scent became so strong it tickled his nose. Unable to resist the urge to sneeze, Dean turned his head just in time. “Ihhschoo! Yihshooo! H'shooo! Huhtchooo!” The sneezes were rapid bursts that took over his whole body for a moment. They were strong, irrepressible, and decadent. “heh... found... hahh found one! Hahtchuhh! Ihhtttchhhh!” He rubbed his itchy, tickly nose against Cas' abdomen, loving the feeling of giving his nose attention while still making it sneeze some more. “Ihhkshhh! Hihshhoo! HIHtchooo!”

“Dean?” Cas' hand caressed the back of Dean's head, stroking gently. “Are you all right?”

Dean lifted his head to catch his breath and gazed into his angel's deep, caring eyes. “Yeah... Ihhh I hihhhh Ijusthaveta HIHH Hih-IHTshhhhhh! Sniff! I'm okay.”

 “Then I believe you need to press a certain button.”

Grinning but keeping his eyes locked with Cas' as one hand reached down and turned the vibrator up a level. The soft, almost imperceptible hum increased in frequency and pitch, and Dean sighed happily to discover he didn't come right there on the spot. Given the choice, he might have done so, but he wanted to make this last, wanted to draw out the torture and pleasure to their highest amounts.

As he moved on to find spot number two, Dean's nose was still tickling. Deciding he might as well continue in the direction he had been going, he unbuckled Cas' belt and slid it off around his waist, one belt loop at a time. The vibrations at his crotch were more intense now, and he couldn't afford to waste time, but taking off an angel's pants was as holy an experience as Dean had ever had, and it couldn't be rushed.

Unexpectedly, Dean got lucky as he began to slide Castiel's trousers down his legs. When he neared the angel's inner right thigh, the itchy, allergic tickle flared in his nostrils so intensely all he could do was press his nose against the warm skin. “I... I... I...” Dean tried but couldn't warn him. The reassuring way Cas' hand stroked his back, however, told him not to worry. “IHHTtttchh! H'tshhhh! Ehshhfff! Httttchhh! IHHTchhhh! Hehhhshhhh! Ehptschhh!” Cas' thigh was wet now, but still that hand rubbed up and down, ceasingly supportive. “IHHTch! Chhh! Chhhhh! HEHPTShhhh! Ktchhhfffff!” Rubbing his nose against Cas brought only momentarily relief, just like the sneezes themselves. “Ihhkchhhh! Hehtshhhhh!”

Dean sat up, scrubbing the back of his wrist under his nose and sniffling.

“Can I get you a tissue for your nose, Dean?” The angel was all soft and caring in this moment, and normally Dean loved that. Today Dean wanted rough and wild and unbridled. So he shook his head.

Castiel pulled Dean's hand away from his face and kissed the palm. Then he guided the hand down, indicating Dean was to increase the vibrations one again. As soon as Dean pressed the button, he moaned in pleasure. It was almost too much for him. The cock ring was on securely, but it wasn't snug enough to prevent him from coming if he was pushed that far.

What's worse was that after so many sneezes, his nose was a little stuffed-up and runny, and he couldn't smell as well. He stripped Castiel of his pants completely and sniffed in hard, but unfortunately he didn't feel the overwhelming urge to sneeze again. So he worked his way back up Cas' body again. He pulled the angel's tie over his head and pushed back the angel's shirt. He sniffed one side of Cas' body then the other. He sniffed at Cas' back and neck. He even checked Cas' fingertips. Just when he was considering giving up, his nose slid across the curve of Cas' shoulder and prickled with the urge to sneeze.

The spot Cas had chosen was the same one where Dean bore Cas' mark, his hand print. Dean really should have guessed. As he nuzzled his face close, he trapped Cas' leg between his as well. He really didn't need the extra friction and rubbing against his cock but, oh, he wanted it. The urgent, hitchy breaths demanded it. “ihhhhh! Hihhhh! HIHHHH!” His eyes began to tear up and his body began to shake. The vibrations and tickles consumed him, controlled him, elevating him to a level he never would have got to on his own. It was a place just beyond discomfort, heading into ecstasy, and he was teetering right on the edge of what could easily be the best orgasm of his life.

Just a couple more sneezes should do it, and his nostrils already twitched wildly against Cas' cologne-covered upper arm. “Hehhhhhhhhh!” His breath raced almost as fast as his heart. His fingers scrambled for purchase, one finding bed sheets and the other finding Cas' other arm. Dean clung tight as the strong sneezes finally struck. “IHHTchooo! HIHtchhhh! Ihhhkkschhhh! HEHTchhhhhhh!” His hips thrust, body gyrated. He gave into the pleasurable sensations of release. “HehhhIHHHHShhhh!” He was so full and so ready, as he covered Cas' thigh in ribbons of come.

“ihhhShhhh! Hihshhh! Hehtchhhh! Hehffschhhh!” It was impossible to know which had finally tipped him over the breaking point, the vibrations or his sneezes, the two were so intrinsically linked, making his whole body tingle and shake. “Hihshhh! Ihhpshhh! Ehhhtshhh! Hihh HihhIHTchh!”

But he knew which was the first to end, because he reached down and switched the vibrator off as soon as he was spent. His crotch almost felt numb now, like it was still vibrating. And even though the rush of orgasm was gone, the pleasure remained. So did the sneezes. “IHTchhhhh!” He leaned to the side and rubbed his face in the sheets, snuffling and trying to rub away the tickle still present at the back of his nose.

“Here,” Castiel touched a finger to Dean's chin, and for a moment Dean thought Cas was going to use his powers to drive all this away in a split second. Instead, Cas guided Dean's head to the side where it met with a handkerchief. Where Cas had gotten it, Dean didn't know. Had it been in Cas' pocket the whole time? Had Cas summoned it? It didn't matter, though, because it was dry and soft and thick enough to withstand three more sneezes and all the blows it took for the tickle to finally back down again.

Nose calm, body still, Dean lay back against the pillows on a dry patch of bed and let his breath and heartbeat return to normal. It took Cas less time to clean himself off. One moment he was a mess and the next he was dry, free of cologne, and wrapped around Dean.

“I still don't think I understand why you wanted to put yourself through that,” Castiel admitted as he hugged Dean to him. “But you did seem to enjoy yourself.”

“Mmmm,” was all Dean could manage. He'd thank Cas later, when he'd regained the ability to talk. His angel might not understand how fantastic it felt to be pushed past your limits, to be helpless and vulnerable, to be teased and tickled, but his angel definitely understood how to offer care and time to recover afterward. With his cheek pressed to Castiel's warm chest, Dean allowed himself to bask in the afterglow for as long as it lasted.
