Stiles has this look on his face, like he's anticipating something tremendous and it's all feeding into Derek's need to be seen; to be put on display. Really there's only one way this is going to go. Derek stands up, grabs Stiles' hand, pulls him up too, gives him a swift kiss and drags him into the house. He doesn't feel like stopping when they're immediately inside so he carries on, towing Stiles upstairs behind him because, after all, that's where the rest of his lingerie collection is.
It's not like Stiles is in any way reluctant to follow him, he's almost tripping over his feet in his haste to keep up with Derek. When Derek turns to face him again in his bedroom, Stiles' expression has added surprise to anticipation but his heartbeat's way up and Derek can maybe detect an aroma that emanates from Stiles that seems like musk and spring: fecund.
"This..." Stiles shakes his head like he's trying to dislodge an inconvenient thought. "I never thought, in a million years..." He simply stares at Derek as if he's never seen him before and has to take it all in.
"Do you want to see or not?" Derek's getting a little self-conscious now, there's still time for this all to go horribly wrong but Stiles senses Derek's insecurity and he reaches out and reels him in close.
Stiles runs a hand down Derek's chest towards his waist. "I can't think of anything in the world I want to see more right now. Can I..?" And he tugs on Derek's jeans.
Derek swallows and nods, there's this huge lump in his throat and he doesn't trust himself to speak. He's so excited, he's halfway to a splendid hardon and he knows the minute he sees Stiles' eyes on him, it's going to go monster. He still has a tiny niggle of doubt though, the idea of - quite literally - exposing himself is a petrifying one but so, so what he craves. He asks...
"Are you really OK with this?"
Stiles is fumbling with the button on Derek's jeans now but he still manages to cup Derek's face with his other hand. He tilts his head and regards Derek with a soft smile.
"I am beyond OK with this." His thumb is rubbing gently over the stubble of Derek's cheek. "I would have been doing this years ago if I ever thought I had a chance in hell – with or without panties." His fingers manage to flick open Derek's jeans.
"They're an amazing bonus, like something you never thought you'd get."
Stiles has now opened Derek's jeans and is inching his fingers inside, glancing against the silk underneath. Derek can't choose between watching Stiles' face or the reveal itself. He decides that he'll never get another opportunity to see Stiles' very first reaction to his choice of undergarments so he relishes the sensations but keeps his eyes on Stiles, he is not disappointed.
Stiles honeyed eyes go wide and dilate, his mouth gapes slightly and he looks like pure, undiluted sex. Derek can imagine throwing him down on the floor and just taking him and Stiles looking up at him exactly like that.
Stiles' hands are on his hips under the jeans but over the panties, he works Derek's jeans down so they tumble around his legs.
"Oh", sighs Stiles, long and drawn out, he looks up at Derek, "Fuck!" He pushes Derek's shirt up round his waist and holds it there so he can just go back to looking. There's so much tension in the room now, the air seems heavy and volatile. Derek can't bear it any longer so he grabs Stiles' face and kisses him deep. They part, panting shallowly.
"You need to get this off." Stiles pulls at Derek's shirt so Derek lets him drag it up over his head while he toes off his shoes and kicks his jeans from his legs. Stiles stands back a little to fully absorb the sight of Derek, naked and in frilly panties.
"Look at you", Stiles says breathlessly. "You're stunning, so hot, so pretty." He runs the back of one hand down Derek's belly, grazing his treasure trail until he reaches the panties.
Derek's earlier belief that the very act of Stiles' looking would make him hard is difficult to disprove when his cock is clearly visible, bulging lewdly right in the front of the otherwise demure garment.
"And you love this, don't you, you're so turned on." Stiles gives a little smile, one of satisfaction and slips a finger under the elastic of the waistband, a hairsbreadth away from his cockhead. He runs it teasingly across the sculpted terrain of Derek's abs. Derek just has to shut his eyes for a moment, Stiles' touch on his skin sending his senses into freefall.
Derek can't even put into words the way the sensuality of the fabric makes him feel so he just says, "Yes."
Stiles drops to his knees in front of Derek, he has his head tilted to the side and his breath is caressing Derek's thighs. He runs his hands slowly up Derek's legs, against the growth of dark hair there, sending Derek into sensory overload. The sensation of Stiles' hands on his skin is like a warm bath, perfect and comforting. Derek wants to subsume himself in this; he wants Stiles' hands everywhere. He thinks that he must be looking like sex right now as well.
"I want..." He stutters out lowly but he doesn't even know what he wants. He tries to get himself together enough to work it out. "I want you to tell me what you think."
Stiles' hands are on his thighs, fingers edging up under the loose legs of the ruby red knickers.
"It's like every fantasy I've ever had come to life in front of me. You're the benchmark for attractiveness; all the things I find desirable in a man, you're that. C'mon, Derek, you've got to know that I've wanted you for years."
"No, I had no idea." Derek says quietly and he really didn't, maybe he'd have done something if he'd have known.
"Well I have." Stiles drops his voice to a confessional tone. "I turned around one day and you were a fixture in my life, I couldn't imagine what it would be like to not have you there." Stiles' hands are now inches from Derek's groin.
"You never said anything", Derek questions.
Stiles fixes him with a baleful look. "I wasn't stupid; I got about as many sexy vibes from you as I did from Scott. The last thing I wanted was to blow our friendship."
And Derek knows this is true, last week this thing between them was a possibility too bizarre to be considered; now, it's the only thing in Derek's future. Stiles' thumbs are stroking the top of Derek's thighs, right where the hair starts to grow thicker and curlier. He's flexing his fingers under the loose silk of the panties and it's driving Derek wild.
Derek needs to touch now, he's being touched but he has to have it too, to know what Stiles feels like under his hands, how warm he is, what the texture of his skin feels like. He reaches for the nearest exposed part of Stiles he can find - his neck, so smooth, so luscious. He slides his hands down to the collarbone, relishing the play of skin over bone. He can feel Stiles shudder at his touch.
"You know I'd never have let that happen, you're too important to me." Derek grips Stiles just a little bit tighter and in return Stiles grazes his thumbs higher, signalling his eventual intent. Derek watches Stiles as he in turn stares in wonder at his own hands moving over Derek's body, shifting the delicate silk, making the ruffles quiver.
"I think there's a time for things", Stiles declares. "I think there's a moment when everything's right and I think our moment is now." Bending forward he presses a kiss just below Derek's belly button.
"You're all muscle and tan and hair and what do you know, my type just happens to be dark buff dudes with plenty of body hair and a bit of an attitude. " He slides his lips down the soft dark path on Derek's abdomen. "Christ, Derek, I could do this for hours", he sighs.
Derek pulls Stiles close against him. "I could let you." Stiles nuzzles his cheek on the silk and lace. "These are so pretty and you look so good in them, I can't tell you..." He looks up at Derek with longing shining from his eyes and then gives a small smirk. "One thing you don't know about me - because, why would you - is how very kinky I am." Stiles is rubbing the silk of the panties between his fingers and thumb, so near to Derek's throbbing cock, he can feel the fluttering of the fabric against his too-tight skin, it's intoxicating.
Stiles sits back on his heels still with his hand on the jewel toned delicacy covering Derek's turgid manhood.
"I'm going to wreck you Derek Hale, I'm going to take you apart and when you think you're spent, I'm going to whisper to you all the things I've thought about doing to you, tell you all the things I'd use on you – oh, I've got quite the collection – and then I'm going to do them." He flashes a wicked grin and leans in closer to Derek, pouts his plush lips and places a kiss dead centre on the soft red silk, right on the burning head of Derek's cock.
Derek's knees buckle a little. "Do it", he growls, "Do it all to me, I want you to."
"Oh I will but I want you to promise me something first..."
"What? Anything..." Derek stutters back, it's overwhelming, he needs Stiles so much right now, he'd probably sell his firstborn if Stiles would just touch him again.
"Keep these on, always keep them on for me. You have others don't you? Yes. Of course you do, I've seen them. Always wear something pretty for me." Even Stiles' self-assurance is starting to crack now. Derek wraps his hand round the back of Stiles' head and pulls him sharply in to his groin."
"God, yes, Stiles, I want to look pretty for you."
Derek's experiences of sex thus far - while varied, particularly in slutty phase – have been mostly completion driven; foreplay usually a means to an end. He prides himself on being good at it, on bringing pleasure to his partners but he realises he's only ever done just enough to suffice, just enough to race to the finishing line. Stiles is mouthing at his cock now, arms wrapped round his thighs, darkening the already deep colour of the panties with his saliva and Derek's loving it, never wants it to stop, understands now that sex is a journey, not only a destination . He knows he wants to take his turn too, wants to strip Stiles down, infinitesimally slowly and discover all the parts of Stiles, with his mouth, his hands and his mind. Right now though, he's Stiles' to play with, he belongs to Stiles, totally.
Which is why it's such a disappointment when Stiles stops sucking tight kisses along his shaft and pulls away. He taps Derek on the ass, hand sliding on the slippery silk. "Get on the bed big guy", Stiles tells him and he scrabbles backwards to comply. Stiles clambers on after him, kneels between Derek's legs, looking.
"So beautiful", he says running his hands down Derek's torso, tangling his fingers in the not inconsiderable fur on Derek's chest. "I love how hairy you are, it does something for me." Stiles' fingers find Derek's nipples, he drags a nail over one of them and Derek bucks up, rubs his dripping cock against the wet fabric of the knickers, finds a little of the friction he's needing. He's not above begging now.
"Stiles, please...touch me...something, anything...please..." Derek can hear the desperation in his own voice.
Stiles shuffles closer and gently reaches across to pull the panties down, having to lift them up and over the prominent bulge of Derek's desire. It springs free, a drop of pre-come flicking off the head. Derek watches it fly away. Stiles tucks the waistband of the panties under Derek's balls leaving the silk bunched up around his thighs, he seems transfixed.
"How have you got such a gorgeous cock?" Stiles wonders and he wraps a warm hand round Derek's thick length. His other hand is stroking Derek's leg, pushing up under the silk. Derek has never thought of his or indeed any other genitalia in these terms but he knows with certainty that he will think Stiles' is equally as luscious when he eventually sees it.
Stiles dips down and runs his lips along the shaft, letting his tongue peak out to leave a trail of dampness behind. "You're so hot", he murmurs.
"Ugh" responds Derek, struggling for coherence. "So are you", he manages and runs his hands over Stiles' head, through his tousled hair .
Stiles doesn't even take his mouth away from Derek, he just talks around him sending delicious vibrations right through Derek.
"No, I mean you're hot like burning, in temperature I mean, not desirability, although you're that as well."
"Stiles, please..."
Derek gazes down and watches Stiles mouth envelop him, sees the swallow of Stiles throat as he takes him in, the warm, wet cavern descending down, down until it meets Stiles hand, rolling the tight skin between his fingers. This is heaven for Derek; he can't imagine anything better than the swipe of Stiles' tongue against his heated flesh. It's not enough for Stiles though, he takes his hand away, groping for Derek's balls and lets Derek's cock hit the back of his throat.
"Fuck, Stiles! So close..."
Stiles loosens the suction and lifts up to circle his probing tongue around and over the tumescent head of Derek's dick. Everything's so wet, there's saliva and pre-come dripping down through Stiles' fingers as he cups Derek's balls. In Stiles' hand, Derek feels his balls tightening as Stiles' tongue slips into his slit and presses lightly.
Derek has no idea whether Stiles' preference is to spit or swallow so he tightens his grip in the threads of his hair and pulls him up, away from his cock and into a fierce kiss. Derek breaks off to slam his head back as the rush of orgasm pulses through him and from the corner of his half open eyes he catches the spurts of come as they arc up and land on his chest.
Stiles' finger comes up to swipe through Derek's chest hair and collect some of the come. Derek barely registers Stiles sucking it off the digit.
"Jesus, Derek, you come like a volcano!" Stiles is rapidly fumbling for his own cock and Derek finally gets his own glimpse. It's thinner, paler and slightly shorter than his own but just as hard as Derek was a moment ago.
"Let me...I want to..." Derek reaches for Stiles but gets his hand butted away.
Stiles shakes his head. "No, I want to look at you. " Stripping his cock roughly with one hand, he reaches down and pulls the now soiled panties up again, over Derek's softening cock. "Can you clean these? I mean can I get them dirty?" he pants.
Derek nods; he'll buy a hundred new pairs if Stiles will just keep looking at him like he's the answer to all his prayers. Stiles places his other hand on Derek's hip, fingers scrunching the red silk. He's breathless now, mouth slack but eyes fixed on Derek lying there, debauched, come on his chest and filthy panties clinging to his groin.
"So sexy", he groans, "So hot...gorgeous...let me come on you, please..?"
"Yes." Derek can't say it quickly enough. Stiles' hand is moving so fast Derek's worried he's going to hurt himself but he slackens his grip, points his cock at Derek, tugs it a couple of times and his seed spills from him dripping down to soak the ravaged panties.
Stiles collapses exhausted at Derek's side and Derek has the presence of mind to catch him and draw him in for a slow kiss, lips sliding together, tasting the last vestige of his own come. He holds on tight to Stiles. He decides he never wants to let go.
"I think you wrecked me instead", Stiles finally manages. "How are you such a surprise, after all these years?"
Derek shakes his head. "I dunno, just comes naturally, I guess."
Stiles slaps ineffectually at him. "You have more of these, right?" He indicates the silk that he marked so decisively minutes ago. "You'll show me..?"
"Yes", Derek says, pressing a kiss to Stiles' temple, "but later, just want to cuddle now."
