Chapter Text
Scott will always believe Allison was his great true love. But that doesn't mean they weren't wild and experimental in bed. What he loved best was when she would ride his face and all his senses were full of nothing but her. It was, tragically, an impractical act when they relied on those supernatural senses to detect her parents pulling into the driveway. But still, it was and is the stuff of all of Scott's hottest fantasies, his hands gripping her ass as she moved against his mouth, the taste of her everywhere.
Scott fucks Derek like an Alpha. With Derek he lets his instincts out, because he knows it's what Derek craves. He growls into the hollow of Derek's bared throat and runs clawed hands over the soft flesh of Derek's belly until he's whimpering with want, then Scott will whisper into his ear, his voice vibrating with an alpha's commands, "roll over."
He's never rough. He fucks Derek like a good alpha, using his power to make Derek feel good. He fucks Derek steadily, until Derek is incapable of human words. And when they are done, he places soft kisses all over Derek's face and throat, petting his hair and whispering, "you're so good."
Stiles is the only person he can actually relax with. It makes him strangely sad sometimes to realize that Stiles is the only person who really knew him before, when he was just an asthmatic loser, and as time passes, soon it will be only Stiles who has a reference point for what he was like before he was an Alpha wolf.
Maybe that's why he likes it so much when Stiles fucks him. Then he's just a boy, who loves this other boy, who is is best friend and he can pretend all this supernatural stuff never happened. Maybe it's because there's no difference between how they are together as lovers and how they are together any time, so that they can be lounging on Scott's bed while Stiles' jerks him off and Stiles can say nonsense like, "You know, Scotty, you have a really nice cock. It's big, but not, like, freaky scary big. It's a nice color, soft. Well, not soft, but y'know, really nice and touchable. I just really like your dick, man. I like a lot of things about you. I like your smile. I like your weird crooked jaw. I like your eyes. But I also like your cock, like, a lot."
Scott's pressing his face into Stiles' shoulder and laughing so hard he can't catch his breath and thinking that only with Stiles could he come so hard in the middle of hysterical laughter.
He's already half-undressed in Lydia's bedroom when she says, "You're not going to fuck me, Scott."
"Um..what?" He says to her, because of course, he thinks, Lydia Martin has him completely confused before they even start to do anything sexual.
Lydia just continues to strip down to set of lacy purple lingerie, which, of course, Scott thinks, of course, Lydia Martin wears elaborate lingerie to a casual hook up. She says, "We're not fucking. I've given up letting random boys put their dicks in me, even very nice boys like you. It's not worth the hassle."
She pushes him down onto her bed and grabs his jaw forcefully, like she's about to scold him, but instead she smiles and says, "I have heard from now multiple sources that you have a very talented tongue and I intend to take advantage of that."
With that she stomps over to the other side of the room and lays out on the chaise longue. He looks up the word later, so he can the sentence, even just alone to himself, "I ate Lydia Martin's pussy while she reclined on a chaise longue in a purple lace bra that is probably worth more than any one thing I own."
He wishes he could send a message back in time to his 15 year old self that would go something like: Some terrible things are going to happen to you. You're going to see a lot of violence and death but also one afternoon you're going to be shirtless in Lydia Martin's bedroom and she's going to lay back in her expensive underwear on her chaise longue and beckon to you like you're a dog and it's going to be the hottest thing."
When he gets down on his hands and knees to crawl over to her, Lydia claps her hands with delight, like he's caught on to her game. He kisses up the inside of her thigh, which is just as smooth and white as it's been in his awkward fantasies. He's almost reverent as he slides his hands around her ass to remove her panties then presses his face between her legs. When he first presses the flat of his tongue against her clit she hums with satisfaction.
There's a part of him that just wants to impress, or live up to the reputation he's somehow gathered, but another part of him is just narrowly focused on the feel of her body quivering above him and the breathy, un-self-conscious moans she makes as he moves his lips and tongue against her, the feel of her hand tightening on his hair and the taste of her as she presses up against his mouth when she comes.
There's something almost tender in the way she strokes his hair afterwards, as he lays with his face against her belly and a hand across her hips. But better is the genuine friendliness with which she says, "That's was pretty great, Scott."
Stiles isn't even jealous when he tells him later. Or if he is, he's easily pacified with a quick blowjob and confirmation that Lydia's a natural redhead ("Which you already knew, dude. Did you think she started dying her hair in second grade?" "Yeah, but I didn't know, if you know what I mean.")
Scott struggles at first to find balance with Isaac's contradictions. There's a part of Isaac that is so desperate to be loved and so terrified of rejection. The first time they have sex it's less than artful, rubbing against each other while he clutches Isaac in his arms as his moans and trembles out his orgams. Isaac sleeps in Scott's bed now, more nights than not. Scott pulls him close against his chest and wraps his arm around Isaac, pressing his hand against his heart and entwining their ankles. Isaac's dreams start to happen less, and so do Scott's.
But there's also a part of Isaac that's a perpetually horny little pervert, constantly pushing the boundaries of decency. He sends Scott filthy text messages in the middle of class. He jerks him off on a long lacrosse team bus ride, and Scott is pretty sure Greenberg noticed. In what is probably a capital offense against any kind of bro code, Scott ends up rimming Isaac in the back of Stiles' jeep in the school parking lot when they are supposed to be in English.
So, of course, it's Isaac that gets Scott into threesomes.
Derek likes to watch. In a less than charitable moment Scott thinks, of course Derek likes to watch. Of course Derek's approach to a threeway is to sit on the bed and stare. But Scott knows that Derek carries a lot of guilt for how he treated Isaac, and Derek needs to see Isaac being cared for.
Scott has Isaac spread out on Derek's bed, one ankle hooked over Scott's shoulder, and he's taking his time sucking him off. He waits until Isaac's moans are desperate and he's scrambling at the sheets with his claws out, then he pulls off and nibbles at the inside of Isaac's thighs for a while. By the time Isaac's sweaty and desperate, Derek has moved closer and runs a hand down Isaac's chest as he arches up. There's an expression of wonder on Derek's faces as he strokes Isaac's body, and Scott sees him gasp when he runs his thumb over Isaac's lips, only to have Isaac pull it into his mouth briefly.
"You gonna let him come any time soon?" Derek asks, his tone is casual but his voice is hoarse.
"Pretty soon," Scott says with a grin, "Kiss him. Kiss him and I'll let him come."
He then has to add, "shhhhhh, I got you" to Isaac as he arches his back and whimpers with pleasure. Scott relaxes as best he can and takes Isaac deep in his throat, and as he looks up he sees them kissing deeply, Derek's hand tangled in Isaac's curls. He holds Isaac's hips down as he comes down his throat. They'll be bruises later.
When crawls back up the bed, Derek and Isaac are still wrapped around each other, Isaac catching his breath and Derek leaning over to kiss Scott, greedily licking into his mouth to taste Isaac on him. There's something undefinably satisfying to Scott about being here, with his two beautiful beta wolves, hungry for him, something that makes him feel the need to let out a low growl and nip at Derek's throat. And a few minutes later, when they're all three lying on their sides, as he fucks Derek so slowly and careful while Isaac strokes him in time, it feels so perfect and right. He pulls Isaac forward for a kiss over Derek's shoulder and when they break apart he sees Isaac's eyes are glowing yellow and he has the most peaceful expression on his face.
Isaac asks for it for his birthday, though he adds, quickly, "I mean, if you two are both okay with it." He even blushes.
Allison and Scott have a week to work on the details. It's a week of whispered conversations in the library, eventually interrupted by Stiles and Lydia who were convinced they were hiding some terrifying new supernatural threat instead of painstakingly negotiating their emotions around Isaac's birthday threeway. Stiles and Lydia are, of course, embarressingly over the top in their support of the idea and Allison eventually has to corner Stiles in the hall and tell him to stop sending her porn clips for "reference".
She climbes in Scott's bedroom window the night Isaac turns 17 and he pretends to be a lot less surprised than his heartbeat reveals that this is really, actually happening. As they peel Isaac's clothes off him, Allison realizes how much she could come to love this new thing she and Scott have, as friends and teamates, taking charges and protecting the people they both love. And she realizes how much fun it is to make Isaac blush.
"We thought, at first," She says, as Scott licks up Isaac's neck, "That I could ride you while Scott fucks you, like a happy birthday Isaac sandwich. I was confident that between the three of us we could make the mechanics of that work. I was a very good gymnast, you know."
"But," Scott says, lifting his mouth off Isaac neck while Allison kisses down his chest, "We decided it was one of those things they do in porn for shock value that are a lot less fun real life."
"So " Allison adds, "We figure we'll just play it by ear. See all the different ways we can make you feel good."
They end up sweaty, stick and gross, and they lose track of time, so that by midnight, when Melissa's headlights shine in the driveway, all three of them run, wet and naked out of the shower, attempting to be dress and on the couch before she walks in the door. Melissa is cleary not fooled by their deception but she doesn't say anything.
