Chapter Text
"No," Dean said. "Fuck, no, Cas. Come on."
Cas blinked up at him. "You said you'd show me.
"Yeah, but -- Jesus, no. I didn't mean I'd show you show you."
Cas watched him for a long moment, frowning slightly.
"I don't understand," he admitted, finally. "Women often wear boxer shorts, do they not? Which are considered men's? I don't understand the difference."
Dean realized the angel was not, for once, intentionally fucking with him. He sighed.
"Look, Cas, if you wanna try out a panty kink you can put 'em on."
"All right," Cas replied, completely unfazed. "But I want to see you, too."
Dean groaned. He hooked a finger under the cheap white lace and dangled it. "Where did you even get these?"
"At a Wal-Mart," Cas said. "In Peoria."
"In Peo- -- you know what, I don't wanna know," Dean said, shaking his head. "Wal-Mart, though? Really? Couldn't even go all, y'know, Frederick's of Hollywood?"
Cas just looked at him quizzically, and Dean sighed again. He knew he was teetering on the brink of some line he wasn't sure he wanted to cross, but he looked at Castiel, the sincere confusion in his face, and he sat down on the bed next to him.
"Look, Cas," he said. "In the first place, I know you don't have all the stigmas built up in your brain. But I do. Even if they don't make sense, they're there. Especially with my dad's shit parenting, I'm amazed I'm not a totally fuckin' repressed closet case."
Cas blinked at him, surprised. "You couldn't ever be," he said, leaning in kiss Dean softly. "What's the other places?"
"What?"
"You said in the 'first place'. Implying other places."
Dean laughed. "You're impossible." Cas scowled, and Dean raised his hands. "Okay, okay! In the second place, um…" He bit his lip. "Look. Think about texture." He dragged the scratchy fabric down Castiel's cheek against his stubble, and Cas flinched. "Yeah," Dean said. "Now imagine that on your junk."
Cas turned it over in his head. "I think I understand," he finally said. "That does seem unpleasant. But… what would feel good?"
Dean cocked his head, considering, then reached out to grab the tie Cas was still wearing. He slid the silk down Castiel's jaw, rubbing it gently along his lips. He opened his mouth slightly, and Dean swallowed.
"See?" he said, dropping the tie back to Cas' chest. "Wouldn't that feel nicer wrapped around your cock?" He bit his lip and tried to stop himself from imagining the sensation.
Cas stared at him, considering. There was a slight rustle and the air flickered for a second, and then Cas was pushing a plastic bag at him.
Dean raised an eyebrow. "Really, Cas?" he said with a small laugh, but Cas just waited, his expression unreadable. He sighed and opened the bag, pulling out something pink and satiny.
They weren't that bad, really, he had to admit, though he cringed at Cas' choice of color. Fairly basic, no little bows or ribbons, only a little bit of lace at the hips. Kind of like a Speedo, Dean thought, rubbing the fabric idly between his fingers. A really... silky Speedo. And, yeah, he was definitely picturing how that would feel instead of the soft flannel boxers.
“Why do you even want to see me in these?” he asked, playing for time, trying to ignore the undeniable tightness in his jeans.
“You know that I find you to be a beautiful man,” Cas said. “And I find the aesthetics of that choice of underwear appealing. Is that really so strange?”
Dean fidgeted. He knew his argument that they just weren’t fucking for men would be dismissed, and if he was being honest with himself, it sounded a little ridiculous even to his own ears.
“Fine,” he muttered, looking away and flushing hotly. “But you fucking owe me.” He reached up to unbutton his shirt, but Cas stopped him with a hand on his knee.
“Dean,” he said, and Dean met his eyes reluctantly. “If it truly makes you uncomfortable, you don’t have to. I don’t want to pressure you.”
Dean snorted a laugh. “Thought you liked making me uncomfortable,” he mumbled, and Cas smiled slightly.
“Yes. In certain circumstances, very much. But not this. I just think you would look... very arousing.”
Dean groaned in defeat. “It’s ridiculous how easily you get past my defenses,” he informed the angel. “I don’t think you even know you do it.”
“Sometimes I do,” Cas whispered in that voice that made Dean’s dick throb. He reached up to his shirt but Cas stopped him again. “Let me,” he said, and Dean dropped his hands away.
Cas unbuttoned his shirt slowly, following each bit of exposed skin with his mouth. By the time Cas pushed the shirt off his shoulders, Dean was relatively sure that if Cas asked him to wear a fucking prom dress he'd just be asking for a list of boutiques.
Cas went to work on his jeans just as methodically, unpopping the button and pulling down the zipper tooth by tooth. He gave Dean's aching cock a nuzzle through his boxers but didn't linger there, instead pausing to suck hard at each hipbone, and Dean jerked.
"Cas," he moaned, but Cas only hummed in response, continuing to work the jeans off and worship Dean's skin. He finally pulled them off and dropped them to the floor, crawling back up to toy at the waistband of Dean's boxers.
"Cas," he repeated, voice rough. "If you don't hurry it up, you're not gonna be able to enjoy me in those pretty pink panties for long, buddy."
Cas just smiled. "No," he said thoughtfully, "I think I'll enjoy it just as much after you've come in them."
"Oh, God, Cas, please," Dean choked, and Cas took pity on him, sliding off his boxers and tossing them aside.
He paused, lingering on the picture of Dean laid out on the bed, bare and wanting, with that intense, unwavering gaze that made Dean feel like he was finding new and undiscovered levels of naked.
"I'd ask if you like what you see," Dean said, trying for levity but betrayed by his voice cracking traitorously, "but I think your dick's announcing it pretty loudly." He glanced down at Cas' obvious erection, but Cas just blinked at him, and damn him for his angelic lack of shame.
"You know I like what I see, Dean," he murmured. "I find you very arousing."
"S'good," Dean said, squirming. "Be a little awkward right now if you didn't."
Cas drew a finger down his chest, then picked up the panties from where Dean had dropped them on the bed, draping them over Dean's cock.
"How does that feel?" he asked.
"Um... soft," Dean said. "Cool and -- cool and soft."
Cas reached up and squeezed him gently through the fabric. "Do you like it?"
"Fuck, Cas," Dean groaned, and Cas tightened his grip.
"Is that a yes?"
"Yes," Dean spit out, blushing, and Cas smiled, leaning in to press a long kiss to his mouth.
"Do you want to wear them?" Cas whispered, moving his lips against his neck, and he could feel Dean's teeth clench. He rubbed the fabric over the head of Dean's cock. "Or I could stop touching you," he offered.
"No," Dean said, face burning.
"No, you don't want to?"
"No, don't stop touching me. I'll put them on."
"I didn't ask if you'd put them on, Dean," Cas said into his ear, dropping his voice. "I know you'll put them on. I asked if you wanted them on."
"Yes," he ground out. "Yes, I want them."
"Ask me nicely," Cas all but purred. "Ask me nicely and I'll put your pretty little panties on you."
"Fuck, Cas," he begged. Cas just sighed and moved his hand away.
"That isn't asking very nicely." He trailed his hand upwards, then twisted roughly on his nipple.
"Please," Dean cried out reflexively. "Yes, please, put them on -- put my panties on me."
Cas let out a low moan, his cock jerking painfully at Dean's words. "Good boy," he said, biting gently at Dean's ear. "That wasn’t so hard, was it?"
He moved down Dean's body, dragging the silk off Dean's cock slowly, already damp in spots with precome. Castiel brought the material to his lips, inhaling faint traces of Dean's scent, and Dean growled.
"I love the way you smell," Cas said, sincerely. "Your skin smells like outdoors. Like leaves, and leather." He kissed the inside of each ankle, then hooked the panties over Dean's feet, tugging them up his calves. He bit Dean's shinbone, and Dean yelped; he licked the tiny red dents apologetically.
"Like the Impala, and your jacket." He inhaled further, pulling the silk up almost absently. "Like autumn," he continued. "You remind me of October, have I ever told you that? If October were a person, with a soul, it would be you. Maybe that's why your soul glows so bright and gold."
Dean was panting audibly, between the sensations moving up his body and the intensity of Castiel's words. He shifted his hips, and Cas finally pulled the waistband up and over his hips, then leaned back, then leaned back, staring up and down Dean's body.
After few moments passed, Dean opened his eyes. "What?" he snapped, clearly self-conscious. "Changed your mind?"
Cas smiled at him and bent down, mouthing at the wetness leaking through the fabric. Dean's breath hitched.
"I want to make you come like this," Cas said against the material. "And then I want to fuck you. May I?"
Dean let out a whine. "Gonna make me come like this whether you want to or not," he said.
Cas mouthed at his cock, then pulled off. "I wish you could see yourself," he murmured, slipping his fingertips under the waistband at his hips. "You are art.
"Cas, please," Dean whispered. "I can't hold off much longer."
Cas licked a long, wet stripe along Dean's cock, then sucked the head into his mouth, precome dripping onto his tongue even through the material.
"Cas, Cas, I can't --" His hips jerked and he cried out, and Cas could feel the hot liquid pooling under his tongue as he came. He twitched, gasping. "Cas, I'm sorry, I couldn't --"
Castiel just smiled at him, soft and sweet. He carefully sucked at the fabric, tasting Dean's come seeping through, and pressed slow, gentle licks, then pulled off, stripping off his clothes.
"I wish," he said, looking up at Dean, then paused. "Do you know what you look like to me?"
Dean gave him a weak smirk. "Hot piece of ass?" he said. "Uh… who's wearing girls' underwear?"
"I remember the first time I came to the Earth," he said, not taking his lips far from Dean's cock. "Do you know that? I remember the first time I saw the sun. It's not like that, in Heaven. So much light, but there's no sun." He sucked harder at Dean's panties, drawing more come through the fabric, into his mouth, and Dean's cock was stirring again, already.
"And I've been here for so long," he continued. "So much beauty on this planet. Even after millennia, it's breathtaking." He suckled Dean down again, and began reaching behind him, under the silk, pressing into him.
"But you can never," he breathed, "never see the firsts again. Never see the sunrise for the first time, again." There was enough come on the panties that Castiel could gather it on his fingertips and push inside.
"But I can," he said, and his voice was raw and open. "Every time I look at you, every time I touch you, it's like I see the sun for the first time, like I smell the rain."
"Cas," Dean said, shaking. "Cas, please…"
Castiel drew back, urging him over onto his stomach and kissing down his back. He slid the silk down his ass, but left it caught over Dean's cock. Aligning himself, he traced one hand down the length of Dean's body.
"You feel like fire," he said, sliding inside and crossing his arms over Dean's hips.
"Jesus, Cas, Jesus, fuck," he said in an endless litany. "Cas, mine, fuck, mine…"
Cas wrapped his hand tightly around the fabric over Dean's cock, and at the second spill of hot liquid he finally let go, twisting desperately against Dean, falling against him.
Finally Dean shifted, and Cas opened his eyes.
"Dude," he said, pulling the silk away from his skin. "Jesus." He yanked the panties off with a squelch. Cas met his eyes for a moment, and they both dissolved into laughter.
Dean rolled over, wrapping his arms around Castiel's chest.
"One of these days, little angel," he murmured, planting lazy kisses on skin. "Gonna figure out what makes you tick."
