"Well, this must be awkward for you."
Derek can"t help the snort that escapes his lips. "Really? That"s all you have to say? And why would it only be awkward for me? You"re the one who - "
"If you can"t even say it at your age, nephew, then there"s no hope for you at all, is there?"
Derek rolls his eyes. "I can talk about sex, Peter. But it"s certainly my fault in thinking that you would have any shame about me finding your - frankly concerning - sex toy collection. I mean, Jesus, how much did all of this cost you?"
"It"s not like I"ve kept all the receipts, but certainly a pretty penny, altogether. Which is why you should put it back before you manage to damage anything. You break it, you buy it, Derek. I mean that."
"Oh, heaven forbid I damage one of your two vibrating butt plugs with a goddamn tail attachment. I mean, really, Peter? I know you can"t full shift, but that"s low, even for you."
Peter arches an eyebrow. "Low ? Tell me, Derek, how is that low?"
Werewolves don"t get headaches, and yet, Derek sure feels like one"s forming in the space right behind his eyes right now. "Are you serious? I shouldn"t have to explain this to you, Jesus Christ, Peter."
"Just Peter is fine, nephew. No need to invoke the lord"s name in vain. Now, shoo. If you don"t like what you"ve seen so far - although I"m sure you like some of it more than you"d care to admit, even if you think the tails are too much - then you certainly won"t like what I"ve just brought home. And I need to wash it and to test it out, so unless you"re going to help me with that, then - "
God help him, but Derek is curious about what Peter could"ve possibly brought home that would be more disrespectful to werewolves than tail-shaped vibrating butt plugs. It"s not even a conscious thought when he interrupts to ask, "What would that be, exactly?"
Peter doesn"t even bother to ask if he"s sure, because he truly is shameless. Derek meant that, when he said it earlier. Frankly, he thinks that Peter could stand to learn a little shame. He just won"t say that to his face, because he can practically already hear him retorting that Derek could stand to learn to be a little more discerning about his partners, and he doesn"t feel like digging all of that up on this random Friday night. Christ, Derek can"t even remember what he went searching for in Peter"s room in the first place, starting all of this.
He just opens that bag that Derek hadn"t even realized was that he was holding. It"s black and nondescript, and Derek finds out why as soon as Peter pulls it out. Because it is a fucking knotting dildo, and Derek feels very suddenly faint.
Derek doesn"t have enough time to school his reaction to that, and by the knowing curve of Peter"s smile, he"s been caught out. Well, it"s not his fault he"s aroused by finding a massive collection of sex toys, even if he finds a few of them...personally distasteful. Derek wishes he could take his initial reaction back, pretend that he finds this one distasteful too, but it"s too late.
"Oh, maybe you"re not bothered by this as much as I would"ve I thought you"d be, after all. My, Derek, dear, you wouldn"t be a terrible, raging, hypocrite by any chance, would you?"
It"s not usually quite so horribly obvious when Peter is being condescending. He"s actually very good about it, and good about being subtle about it, too. But, well, if Peter is treating him like he"s a little bit stupid, Derek kind of feels a little bit stupid thinking about Peter and thinking about this fucking knotting dildo.
He can"t decide if it"s more enticing to think about Peter fucking himself with it, someone (Derek, maybe) fucking him with it, or thinking about fucking himself with it. Or. Peter fucking Derek with it. Yeah, he feels more than a little stupid with arousal about thinking about that configuration of things in particular, even if there"s no way in hell that he"s going to say that to Peter.
"Mmm, I thought so. It"s not a becoming look on you, being a hypocrite."
Derek chokes out a, "Sorry," and it only catches up to him that it"s the first thing he"s said since Peter made the grand reveal after the fact. It"s a weak apology, too, and suddenly Derek wants nothing more than to forget all of this happened and teleport out of this room. But Peter is directly in his path of the door, and he"s still holding the goddamn dildo.
There"s no just walking out of here, but Derek also doesn"t know what happens next. He just...freezes, and he waits. For what, he’s not sure.
Peter, however, doesn"t seem to have that problem. Not at all, actually. He holds the dildo out in front of himself, as if offering it to Derek. Before his brain can catch up with his hands, he"s already accepted it. It"s...well, Derek doesn"t know how much he expected it to weigh, but it feels heavier than it should, maybe.
"That"s alright, Derek," Peter says magnanimously. "Why don"t you make it up to me by being a dear and getting that nice and clean? It"s silicone, so warm water and antibacterial soap will do it, especially for a first clean. Be sure to dry it with something like a paper towel, though, not a towel you or I"ve used. Just because we can’t get ill doesn’t negate the necessity of proper toy care."
Derek"s mouth is drier than it ever has been, he thinks. Then, and only then, does Peter unblock Derek"s path from his room. It"s so that Derek can go wash the dildo, and dry it with a paper towel to Peter"s specifications, or so he can leave.
The fact that he walks out of the room with the dildo in hand likely indicates to Peter that he"s made his choice, though. And he does wash it very thoroughly, with great care, in the kitchen sink. He focuses all of his attention on getting the dildo clean, and very much so not focusing on Peter"s intentions for using the dildo in short order. Normally, he tries to be mindful of how much he"s using with his paper products, but he basically just bunches a ton of them up to make sure that the dildo is perfectly dry and clean.
He tosses the used paper towels in the trash, and then it"s just Derek, holding the clean knotting dildo in the kitchen. He can hear Peter moving around in his room. All Derek has to do walk back there, and then Peter will -
Well, that"s the whole problem, isn"t it? It"s the whole reason that Derek is still standing in the kitchen, clinging to the dildo like it"s a lifeline, even if it"s anything but. He has no idea what is going to happen when he walks back into that room. He does want to find out, even if he"s also nervous about it, so he makes the journey.
There"s a comfort in the fact that this is Peter . His history with Peter is undoubtedly messy and complex, but they"re family. Maybe that should be a reason not to do anything about this, but Derek doesn"t care much for what he should or should not do these days. Thinking that way with a life that has turned out the way that his has feels absurd.
He"s not going to walk around murdering people without cause, or anything, but the rules of morality feel a lot more grey than they did when he was a child. He doesn"t know where engaging in some sort of sex with a frankly ridiculous sex toy with his uncle ranks, but he"s just not intending on expending too much more energy thinking about it, either.
"I was starting to think that you might"ve gotten lost out there," Peter jokes as Derek walks back into the room. And, well, Derek is a little bit surprised to find that Peter"s still dressed. There are some changes, where the bed has been turned down and his shoes and socks have been removed, but it"s almost like Peter was just waiting for Derek to return before doing anything else. He swallows thickly, not quite knowing what to make of that.
"Not lost, just taking my job seriously," Derek says, for a lack of any idea how else to respond. He catches Peter"s pupils dilating, though, and he"s suddenly very glad that he did take Peter"s order seriously. "Here"s this back, then."
He extends the dildo out towards Peter, but he doesn"t reach out to take it immediately. Instead, he cocks his head, considering Derek , not the dildo. He squirms under the attention, and it makes him uncomfortable to have no idea what Peter is looking for. Whatever it is, he must find it, because he hums and finally takes the dildo back.
All Peter does with it is toss it to the bed, though, which deeply confuses Derek.
"Peter? Did you seriously have me clean that just to throw it to the side? What are you doing?"
"Well, since you asked, that depends on you. That dildo is clean and ready to be used. Are you going to help me with it? Or are you curious about taking it? I"m sure I"ll be happy either way, but I have to admit to being deeply curious about where your interests lie, here."
Derek just swallows again. He - maybe he needs a glass of water or something. His mouth is dry again and he has no idea how to answer Peter"s question. Honesty seems like the best policy, here.
"I - I don"t know. It. It all sounds good, you know? I was kind of, well, hoping you were going to decide. I wasn"t expecting you to ask me."
Peter looks surprised, and also delighted, by this news. "You wanted me to decide? How generous of you, Derek. I think that I"ll be happy to share it with you another time, or even later if you wish, but I bought it for myself. I"m certain that I"ll be able to take the knot when the time comes, but I"m curious if you"re interested in helping me take it. Do you want that, Derek? Do you want to plug me with that knot?"
Derek wants that so badly that he experiences a headrush just hearing Peter ask him the question. He doesn"t know exactly what his chemosignals do, but it makes Peter let out a belly laugh. "I"ll take that as a yes, then. My lube is in the nightstand. Why don"t you get that out while I get more comfortable?"
Peter doesn"t pause, then, just expects that Derek"s going to do what he"s been asked to. To be fair, he moves almost immediately to obey, so it"s a fair expectation and assumption. When he turns back around with the lube, he can see that Peter"s stripped out of his shirt and pants, and he"s in the process of getting on his back on the bed in just his underwear.
Derek"s eyes lock on with a laser focus where he can see Peter"s bulging out his underwear at the front. There"s absolutely no way that Peter doesn"t notice, but in an uncharacteristically kind moment, he blessedly doesn"t say anything about it. That doesn"t mean that he"s quiet, though, or that he ignores what"s going on here. It"s only fair, though. Derek would be shocked if Peter just called this whole thing off. And, he reflects, he"d be terribly disappointed, too.
"Why don"t you come get comfortable next to me, for now?" Peter asks. Derek can"t quite decipher what the tone is - it should be condescending, because it"s Peter, but it"s not. It"s more like he"s talking to a wild animal, or a spooked horse, trying to get them to calm down and come to him.
Derek feels a little bit like a wild animal, so maybe it all works out. Maybe Peter is just reading the situation as it is. For someone who loves to make up so much bullshit, he is very good at seeing through it; seeing things clearly.
He gets on the bed, on his side facing Peter while he remains flat on his back. He doesn"t remain that way for long, though, leaning up and getting his face close to Derek"s. It"s a very intimate position to hold, but it also gives Derek all the time in the world to back away. So he can"t say that he"s surprised, or that he doesn"t know, when Peter finally leans in and kisses him.
It"s a very, very brief peck at first. Peter pulls back, searching Derek"s expression again, and he"s so grateful that Peter can read him well enough to know to lean back in.
Derek can"t say that he"s never thought about this for, but he also can"t say that he thinks about it a lot . It"s one of those things that just always seemed taboo enough that Derek never lingered on it. But it"s just as he thought earlier - the lives that they lead are so far removed from what"s normal and natural - that he can allow himself this. It feels good. He"s safe, here, with Peter. Nothing bad is going to happen to him right now. That counts for more than it used to; more than it did growing up.
When he reaches out to tentatively cup the side of Peter"s face, it doesn"t feel wrong. It feels better, more settled, grounding, even. It feels right to actively participate in this; not just let himself be kissed. It feels like cleaning the dildo because Peter asked him to. It feels good.
Peter pulls away again, a little bit later, and he can see the signs of arousal. Peter"s cheeks are flushed, his heart rate is elevated, and his chest is heaving. He knows, because he mirrors all the same signs in his own body.
"Why don"t you take my underwear off, now?"
It strikes Derek that everything - even being asked if he would wash the dildo to make it up to Peter - has actually been phrased as a suggestion; like Derek could take or leave the words and Peter would be okay with it either way. He"s oddly touched by the care. Peter could order him, and Derek would let him. But being asked, and Peter being pleased by Derek doing whatever he"s asked? He likes that. He really likes that.
Peter helpfully lifts his hips as Derek works to pull his underwear down from the waistband. He licks his lips involuntarily as yet another sign of Peter"s arousal - this one a little more obvious than the others - makes its appearance. Delicate isn"t quite the right word to describe Peter"s cock - not with the thickness that it boasts, even half-hard - but it"s still the first word on Derek"s mind. It"s pink, flush with blood, and curves almost sharply up towards his stomach. The head is wet - so wet, actually - and weeping actively. Derek wants it in his mouth. Again, not necessarily a thought he"s explored before, not even just with Peter. And yet, it"s there.
"Can I - " Derek cuts himself off before he can finish the question. It feels almost selfish to ask for more, to ask to touch Peter. The way this has been going, Peter"s been leading. Peter"s doing all the asking.
"Finish your thought, nephew. I"m dying to hear it."
Once again, it should feel condescending, but as far as Derek can tell, Peter is being entirely genuine. It gives him the strength to ask, "Can I touch you?"
Peter laughs at him, but it"s not mean. It"s bright and light and it makes him smile. "I"d imagine our end goal here would be pretty difficult if you wouldn"t. Feel free to indulge yourself."
It"s almost like Peter"s weeping cock is singing a siren song for Derek"s touch, but he ignores it for now. He touches his broad shoulders, fits his palm to the curve of Peter"s throat while he leans in to kiss him. If Peter wants him to indulge himself, then he will. It still feels greedy, but it"s like Peter soaks it in. He latches his own hands to the backs of Derek"s arms, always trying to pull him closer.
Giving Peter his attention almost feels addictive. The feedback loop is positively insane. When Derek wants to explore further and places his hands and then his mouth all over Peter"s chest, he moans for it. Peter says, "That"s a good boy," and Derek thinks he blacks out for a minute.
Maybe it"s a bit of a cliche, but he wants to be good. Peter telling him that he"s good, even while he"s fully indulging himself, that"s fucking amazing. Derek"s come to associate being "good" with sacrifice; with his tendency to be a martyr. He understands that sometimes sacrifice is necessary. He does want to protect this pack, even if it still doesn"t feel like his pack most days.
He tries not thinking about the pack, and refocuses his attention on Peter. He thumbs at the wet tip of Peter"s cock, which draws out quite the moan, before wrapping his hand around Peter and firmly giving him a few strokes.
"Very good, Derek, but don"t get me too worked up. After all, we"ve got a main event to look forward to. Perhaps you could lend me a hand there, next?"
It"s not that Derek doesn"t understand what Peter is hinting at, but, "I haven"t done that before."
Peter blinks at him, then, and a Grinch-like grin grows across his face. "Well, then we"ll certainly have to remedy that, first. How about you watch me, and then we can do a little hands-on learning?"
Peter is definitely being condescending this time, but Derek finds that it doesn"t rub him the wrong way, like it normally does. It makes his blood buzz beneath his skin, actually, and he figures that Peter can tell, given his reaction to Derek"s reaction. It"s - it"s honestly a relief for Peter to be acting a little condescending, and for him to so clearly lay out what he wants to happen next. Once again, not with any expectations attached, just the simple fact of what"s in front of them.
"Okay," he says, still fighting his dry mouth. He finds where he set the lube to the side in favor of touching Peter after fetching it, earlier, and hands it to him. Peter doesn"t ask him to do that, but he looks incredibly pleased when Derek takes the initiative and does it anyway. The pop of the cap is unnecessarily loud in the room. Derek"s struck by the fact that there"s usually some sort of background noise, at least as his sexual experiences have been concerned, but this is different. Silence is the background and everything feels almost clearer, like someone"s turned up the sharpness of the photo frame that they"re living in this room.
Peter slicks up two fingers immediately, but he doesn"t proceed overly quickly with them. He plants his feet firmly on the bed, hitching his hips up both to give himself a better angle and, it seems, to give Derek a better view. He taps his middle finger right on his hole a few times before circling it.
Derek has briefly experimented back there himself, but he honestly didn"t get much out of it. He couldn"t quite find the right angle, and reaching down so far felt awkward, and so he gave up. But Peter? He seems to revel in even the lightest touches to his rim. He"s truly playing with himself, but he seems to be getting off on it. Maybe Derek needs to try again. Maybe Derek needs Peter"s help to try again. He"ll have to ask him about that...later. Definitely later.
Playing with his rim is one thing, but it"s a different thing altogether when Peter finally starts actually penetrating himself on his fingers. He looks like he"s having some sort of religious experience, by the way that he moans and talks about how good it feels and how good it will feel when Derek joins him. He works up to two fingers himself, scissoring them apart and stretching himself, but certainly enjoying it.
He"s going to need more than two fingers" worth of stretching if he wants to take that knot, though, and Derek understands that it"s where he"ll come in.
"Come on, Derek. At least get a finger or two of yours wet, and we"ll see what we need from there, hmm?"
Derek definitely notes the increased desperation that"s in the undertones of Peter"s voice, and it excites him. He dutifully grabs the lube and starts getting his fingers slick, and then he hesitates a mere few inches from where Peter is still working his fingers inside of himself.
"Just one to start with, Derek. Follow my lead; follow the pattern, and then you can start stretching and tugging. But you have to get me used to it, first. I"m a werewolf, and I"m experienced, so you likely won"t hurt me. But you could , and we wouldn"t want that, would we?"
Derek whines in spite of himself, and feels the instant flush of mortification. He"s killed Peter before, for god"s sake. But the idea of intentionally hurting him, especially while Peter is being so vulnerable, makes him sick. He definitely does not want that.
It"s a very foreign sensation. Not just having his finger inside of someone other than himself, because he has had plenty of ill-advised sex before, thank you very much. But having Peter"s fingers in there with him is the part that definitely takes some getting used to. It definitely helps that Peter really seems to enjoy the stretch, even if all Derek is doing right now is exactly what Peter asked him to and following his lead.
"Yes, yes, very good Derek. You can give stretching me further a try now, if you"d like. Just tug out - gently - towards my rim, away from my other fingers. Can you do that for me?"
As he has been this entire time, Derek is still helpless to resist. He does as asked without question, and moans right after Peter does, because he can tell that it feels good. Unprompted, after he does this for a time, he starts tapping his other finger that"s wet with lube at Peter"s rim, the way he"d watched him do to himself earlier.
" Fuck , Derek," Peter pants. "Yeah, you like this, don"t you? I thought you might, but I"m certainly glad I was right. Go ahead, that"s a good boy. Fit your other finger inside."
The visual of Peter"s hole split open on four fingers is entrancing . It sounds silly, Derek"s fully aware, but he can"t tear his eyes away. Not, at least, until they go back to scissoring in tandem and Peter lets out a porn-worthy groan. Then, his eyes start to flick back and forth between Peter"s face and his hole like he"s watching a particularly interesting tennis match. His whole body seems to be reacting, flushing with pleasure, and Derek"s so hard in his pants that it almost hurts. He doesn"t even think about touching himself to relieve the pressure, though. This is all about Peter.
"It"s almost time; I"m almost ready," Peter says, batting a bit weakly at Derek"s arm. "Get the dildo slicked up, would you?"
Derek is loath to take his fingers out of Peter when it"s been so good , but his desire to be good for Peter wins out. He pulls his fingers free and watches as Peter immediately fills the vacancy himself, unwilling to be anything less than full. And, well, Derek"s never done this before, but he can intimate how odd it would feel to have been full and suddenly feel empty. He slicks the dildo up as instructed, and waits. Even with their thorough preparations, Derek can"t imagine the knot fitting properly.
Even the regular girth of the toy is going to be a challenge, but Derek also knows and trusts that Peter didn"t buy this as some sort of trick or trap. He had no way of knowing that Derek would"ve been in his room and stumbled upon his collection. That means that Peter did fully intend on prepping himself and taking the knotting dildo himself. By the size of his collection, Derek knows that Peter has experience with all of that.
All that to say that if Peter bought that toy with the intention of taking it, then he knows what he needs. And besides, it"s like he said: he"s a werewolf and he"s done this before. That must mean that he also knows how to tell if he"s hurt, and Derek will be able to tell, too.
"Are you ready?" Peter asks him, and Derek snorts despite himself.
"Shouldn"t I be asking you that?"
Peter laughs again, genuinely, and concedes the point. "Well, it just so happens that I am ready, so let"s get this show on the road."
He pulls his fingers out of himself, and Derek reaches over to hand him a tissue, also unprompted. Peter takes it, but doesn"t use it just yet. Instead, he uses the hand that"s still slick with lube to pull himself open, providing Derek a very clear target for the dildo.
Just like he would push inside anyone else, he notches the head of the dildo at Peter"s hole. Stretched as he is, especially with Peter holding himself open, it slides inside buttery smooth. Derek keeps it there for just a moment, rocking it very minutely and gently since Peter had seemed to like the attention at his rim earlier, too. It pays off; Peter moans long and loud, and he tilts his hips up as if begging for more.
Derek is of no mind to deny him what he so clearly wants, so he starts moving the toy in, inch by inch. It"s not because he doesn"t think that Peter can take it - in fact he"s reasonably certain that he can , aside from the knot at this point - but he"s fascinated by the way that Peter stretches around the length of it.
He makes a gorgeous sight stretched around the so obviously foreign object. It"s an electric blue color, and the knot"s presence is entirely impossible to ignore. Derek takes his time with it, keeping an eye on Peter"s face and his reactions as well.
Once the start of the swell of the knot reaches his rim, Peter stops holding himself open. Derek holds the toy there for a while, not moving. Peter lets out a whine, eventually, tilting his hips and trying to shift the toy inside of himself. Derek takes the hint, again, and grinds the dildo in small circles until he finds what he figures must be Peter"s prostate.
"Oh, yes, right there like that, Derek. Keep that up."
Derek keeps it up. When it seems like it"s not quite enough any longer, he starts working the dildo back out of Peter and then in, laser-focused on the same spot. This seems to be what really drives Peter crazy; getting fucked with more and more of the toy until Derek"s almost fully pulling it out only to slam it back in. The angle is somewhat awkward, as he"s still on his knees between Peter"s spread legs, but he pays it no mind.
Personally, Derek"s gaze finds itself focusing more on the obscenity of the knot as it hits Peter"s rim over and over again. He thinks it would likely be pretty uncomfortable, but Peter seems to go wild for it. He can"t help but think about the fact that Peter can easily enough do this part by himself, though it must be nice to have someone else doing it, at least from Peter"s reactions. But the knot? That would be a lot harder.
Derek knows he"s going to have to work to get it to stretch into Peter"s hole, and he"s excited about it. Inevitably, he imagines what it would be like if that was his cock. He doesn"t have a knot, of course, but the idea is compelling. Filling someone to the absolute brim with your scent and then locking it inside? It plays to the possessive side of the wolf undeniably.
And there"s the breeding idea, and even if it"s impossible, it"s still hot.
"You smell like you"re having some fun thoughts. Will you share with the class? The more aroused I am, the easier it"ll end up being to work the knot inside. And I must know what has you smelling so delicious."
Derek flushes. Dirty talk isn"t his strong suit - talking isn"t his strong suit - but it feels easier, right here, just with Peter. It"s not that he"s free from judgment - he would never expect that from Peter - but more that he doesn"t need to carry the shame that he typically feels from wanting .
"Well, uh, it"s definitely coming from imagining that it"s me instead of the toy. You - I mean, I haven"t done that before. But the way you looked stretched around it..." Derek allows himself to trail off as a wicked smile overtakes Peter"s features.
"Oh, we can certainly revisit that, later. But that"s not all, is it? Go on, nephew, you"re doing well."
"It"s the knot, too. The idea of having one; filling someone up. The undeniable mark. And - the purpose - "
"Oh , Derek, you never fail to disappoint me. You want me to breed me? Fill me up? Mark me as yours? Make me bear your pups?"
Derek almost comes in his fucking pants, if he"s honest with himself. It feels like there"s nothing but TV static between his ears, and his vision nearly whites out. He knows that he slows the motion of his hand, and it must be frustrating for Peter, but he needs a fucking second to collect himself.
"Yeah ," he finally finds it in himself to say. "I fucking do."
He doesn"t quite know how to put a name to what comes over him, but he starts thrusting the dildo at a punishing pace into Peter. "I want to fuck you. I want to fuck you like I"m fucking you right now, and I want to mark you so that there"s no question about what we"ve done. I don"t have a knot, but I saw plenty of plugs in your collection. I want to fuck you until you"re full; bursting with it. I want to fuck you until it fucking takes; until you look pregnant with my pups even if you can"t actually carry them.
"But right now? Right now I just want to watch you take this fucking knot, and I want to come all over you. Are you going to let me do that?"
Peter whines , and Derek can"t lie and say that it"s not a confidence boost to watch someone who is always so put together fall apart, and because of him. Yeah, sure, maybe his lack of experience and confidence will come back to him after this is finished. He has no fucking idea what just possessed him to say all of that, and act like he"s in charge. Especially when Peter has clearly been the one in charge up until now. But he also finds that he doesn"t particularly care.
"Give me the knot. Just - oh fuck - carefully, Derek," Peter half-pleads, half-moans.
This is exactly what he"s wanted since he saw the toy, even before he knew that he wanted it. He grabs for the lube where he left it on the bed and slicks up the knot again, just in case. They certainly made sure Peter was stretched, and Derek coated the toy well, but it"s been long enough that a little extra can"t hurt. And besides, the sound that it makes is hot, too.
He slows his punishing pace and focuses on the stretch of the knot at Peter"s rim, increasing the pressure on the slower thrusts until it finally breaches Peter"s rim, and he absolutely howls for it. Derek pauses again, mostly for himself, though it seems like a delicious tease for Peter, as well. He"s stretched around the widest part of the knot, just a tiny push from getting it fully locked inside.
Derek pulls it back outwards just a bit, then finally pushes it fully inside. Peter lets out a guttural sound; one that Derek doesn"t even think he means to make. It comes deep from the back of his throat, though, and Derek feels a sense of pride at drawing it out of him. Derek leans down over him to kiss the next sound from his mouth when he twists and grinds the knot from its position deep inside of Peter. He can tell from the way that Peter"s leaking that it"s not going to take much more to push him over the edge.
"You love this, don"t you?" He asks, breathless, when he pulls away from Peter"s mouth. He chases him, just a bit, seemingly unconsciously. Frankly, Derek"s not entirely certain that the question even fully registers with Peter, given his state. He rocks his hips against where Derek is still grinding the toy inside of him.
It"s explosive, for lack of a better word, when Peter comes. His hips push back at the same time that Derek pushes and the pressure against his prostate allows him to come, completely untouched. He spills over his own stomach with a chorus of moans, and Derek keeps grinding the toy inside of him, prolonging his orgasm. Eventually, he leans down again and kisses at Peter"s face and throat, overcome with how much he seems to be enjoying this.
His moans turn to whines, gradually, and Derek stops grinding the toy inside of him quite so harshly. He doesn"t move to pull the knot out just yet, though, waiting for Peter"s instruction to do so. If he wants it out, Derek will pull it out, but he likes the idea of leaving it inside while he gets himself off over Peter.
Speaking of which, since he"s not controlling the movement of the knotting dildo anymore, he"s finally free to pop the button and zip on his jeans, which brings him no small amount of relief. Of course, it"s not enough, it won"t be enough until he comes, too, but it"s a start.
Peter makes grabby hands at him (though he would never admit to something so undignified, that"s all Derek can think of the motion as) and Derek obliges, leaning down over him and kissing him again. It"s slower, not quite as hurried and urgent as the kisses that led up to Derek fucking Peter with the toy, and it drives Derek a little bit crazy. Peter might be sated, but Derek"s still right on that edge of desperation.
He grinds against the bed until Peter shifts and flexes his thigh, and Derek takes it as the offer it is and grinds against him instead. It"s instantly better with Peter"s warmth beneath him, but it"s still not enough. He pulls back long enough to peel off his underwear, then he"s back grinding against Peter"s thigh.
"So good for me, Derek, that"s it. Make good on your promise, won"t you? You knotted me up good, now give me your come."
Derek whines, high and reedy in his throat, and shifts back once again to start stripping his cock over the mess that"s already present on Peter"s stomach. It"s too dry at first, so he coats his fingers with Peter"s load, easing the friction on his cock. It"s undeniably hot too, using Peter"s come as lube to mark him up with his own come.
"Peter ," he moans as he finishes, and it feels like too much. Obviously, what they"ve already done is unbearably intimate, but this feels like an admission of something. Whatever that is that it might be, Peter seems open to it, though. He seems enthusiastic about Derek delivering on his promise and covering him in his come.
The room reeks of their combined scents, and when Derek recovers his higher brain function, he knows he"ll appreciate it. It also stinks of sex, which isn"t directly as pleasant, but he appreciates it nonetheless. No one could question what happened in Peter"s room today. No one with a nose, anyway.
Derek does wonder what it means, and he definitely wonders what it means that they both admitted to wanting this again. He has no intention of starting that conversation with Peter right now, though, not while he"s still stretched open on the knot of the dildo. Not while he"s covered in their combined come and smiling about it.
Not even just a little while later, when Derek"s pulled the toy out as gently as he could, cleaned it, and cleaned himself and Peter up. It"s enough that he stays, wrapped in his uncle"s bed with him. They can talk about it later.
