Work Text:

Lily arches off the bed at his touch, stomach taut and legs spread. James devours her, licking right into her, teasing her. He loves this part, the way he can make her body sing with his tongue, the way her body responds to him. She’s so effortlessly beautiful, and giving her pleasure is his greatest desire. 

“James.” She moans his name like it’s candy, sweet on her tongue, and he wants to taste it, the taste of his name in her voice. He crawls up the bed, peppering kisses along her body as he goes, and finds her lips open and eager. He kisses her hungrily, devouring her mouth, and his cock lays against her warm, wet center. 

He ruts against her, with no real intention, but feeling her wetness coat him as he rubs against her. It’s short lived, however, and he doesn’t get the chance to make good on it. 

“Is that what you call pleasing your wife? Pathetic.” 

James’s eyes sink closed, lips still pressed against Lily’s, as he feels the wash of shame go through him. “I was trying,” he mumbles against her lips. 

Sirius clicks his tongue. “Lily, have you even come yet? Don’t lie now, we aren’t here to spare his feelings.” 

She has, and James knows she has. However, Lily shakes her head, biting her lip as she looks up at him apologetically. James scoffs. “You did. Ten minutes ago, on my tongue.” 

“I faked it,” Lily says, shrugging a shoulder. Her eyes are bright and sparkling, like she’s making fun of him, and Sirius is in on the joke. “Sorry.” 

“Get off of her,” Sirius says. It’s an order, one he expects James to follow. “Let me show you how to actually make your wife come.” 

James kisses Lily’s cheek one more time, then slides off the end of the bed. Sirius meets him there, looking down at his cock, still hard between his legs. “Is that what you were trying to please your wife with?” Sirius wraps a hand around it, and James gasps, grabbing Sirius’s arm to brace himself. “What a pathetic little thing. It’s basically the size of a cocktail weiner. Can you please anyone with this?”

Sirius strokes it roughly, running his hand up and down it before brushing his thumb over the top. He looks at Lily, still splayed out on the bed with her legs spread. “It’s a good thing you called us. You poor thing. You must not have had a good orgasm since you started dating him.”

Lily sighs, an arm draped over her head. “I’ve got some good toys. They’re good substitutes.” 

“Does he get you off with them? Or do you have to do it yourself?” Sirius asks, still stroking James’s cock. 

“By myself,” Lily says. “I do it after he goes to sleep so I don’t hurt his feelings.” 

Sirius turns back to James. “Pathetic. Why don’t you kneel at the edge of the bed and watch me take care of your wife for you.”

“Okay,” James says, moving to kneel. 

Sirius catches him with a hand under his jaw. For a moment, Sirius searches his eyes, and James can tell that Sirius is trying to figure out how he’s feeling before he even asks, “Color?”

“Green,” James says simply. 

“Let’s try that again, then,” Sirius says, his voice going a bit harder. “Since I’m going to fix your mistakes here, I think you should show me some respect. You’ll address me as Sir. Understood?”

“Yes, sir,” James says, and his cock kicks against Sirius’s bare leg when he says it. 

“Good,” Sirius says. “It turns out you can listen. Now kneel, and see if you can learn something.” 

James sinks to the floor at Sirius’s feet, facing the bed. Lily is pushed up on her elbows, legs spread, and from here, James can see her dripping with arousal. He wants to crawl up the bed and taste it, but before he can, Sirius swings his hips and hits James in the face with his hard cock. “Watch me, not her,” Sirius snaps at him. “You don’t have permission to look at her right now.” 

“Sorry, sir,” James says quickly, lowering his head. “Yes, sir.” 

James lowers his gaze, watching as Sirius takes another step and then climbs on the bed. James looks up to watch him as he lays between Lily’s legs in James’s bed. Shame floods him again, that if he was good enough, Lily wouldn’t need Sirius now the way she seems to be begging him with her whole body. 

Sirius takes the spot that James wanted, spreading Lily’s lips open and licking into her. She throws her head back and moans, clearly enjoying herself. Sirius puts his whole face into it, devouring her and licking her clean, fingers pushed inside of both of her holes. James shifts on his heels, wanting to touch himself as he watches. They’re so enveloped with each other that they probably won’t notice if he does touch himself, just a little. 

As soon as his hand comes around his cock, there’s a loud tut behind him. “Do you really think you get to sit there and get off to this after you failed to please your wife?” Remus says. “Get your hand off your cock.” 

James’s hands drop to his sides, the embarrassment growing inside of him again. “Sorry,” he says, turning his head toward Remus where he sits on the couch.

“Don’t apologize to me,” Remus says. He points back at the bed, where Sirius has Lily wound so tight that she looks like she might shoot off the bed like one of the wet start fireworks. “Apologize to Sirius. You’re making him do all the work and still getting off from it.” 

“Sorry, Sir,” James says, though Sirius doesn’t stop what he’s doing in order to respond to James. 

“Sorry for what,” Remus says, leaning forward on his elbows, speaking low and gruffly. 

“Sorry for making you do all the work while I still get off, Sir,” James says, repeating what Remus said. 

“Better,” Remus says. “Now watch as he makes your wife come. You should pay attention so you know how to do it later.” 

James can’t look away from them, where Lily’s hands are trembling in Sirius’s hair, and her toes curling against the mattress. He’s sucking on her clit while fucking both of her holes with one hand, the other reaching up and pinching her nipple as well. Lily is hanging on the edge, needy and aroused, and James can tell the moment that she precariously tips over the other side. 

Sirius licks her gently through it, releasing her nipple and slipping his fingers out of her. He turns to look at James, mouth coated in her release. “That’s how you please a woman,” Sirius says, that posh haughtiness that only he can really pull off filtering into his words, and James feels well and truly put in his place. 

“Yes, sir,” James says, shifting on his knees again. 

“Tell him thank you,” Remus says. 

“Thank you, sir,” James says to Sirius again. 

Sirius huffs. “And you repay me by trying to get off without permission? Someone ought to teach you some manners.” 

“Yes, sir,” James says, head bowed again. 

“I’m going to fuck your wife’s mouth now, until I’m ready to fuck her cunt,” Sirius says. “I think you should turn around and keep Remus’s cock warm until he fucks your wife too.” 

James whines. “But I want to watch.” 

Sirius scoots to the end of the bed, bending over to look at James. “Then you should have thought of that before you touched that pathetic peanut you call a dick, shouldn’t you have?”

“Yes, sir,” James says, and again, shame floods him. He’s so full of it that it feels like it could spill out of him. 

He moves to stand and walk to Remus, when Sirius tuts his tongue again. “Crawl,” he orders when James turns back to look at him again. 

James gets on his hands and knees and crawls over to Remus, who is maybe four feet away, but it feels like he crawls the length of the house with all three of them watching him. He kneels in front of Remus, who sits naked with his hard cock in his hand, and James whimpers at the sight of it. 

“Go on, then,” Remus says, his voice softer than Sirius’s, but only by a touch. “Take it all, too. Don’t leave part of me cold.” 

James takes Remus’s cock in his hand, holding it steady as he licks over the tip. James isn’t as used to doing this as he used to be, and Remus is quite large, so it takes a minute to work his way down Remus’s cock. He does eventually manage to take it all the way to the back of his mouth, but he pauses for a moment to breathe deeply. 

“Is that all you can do?” Remus asks. His words are harsh, but his tone is soft. “Or is Sirius going to have to come show you how to do this better as well.” 

Behind him, Sirius groans, and there’s a muffled sound of Lily moaning as well. James knows that Sirius is fucking her mouth, taking her with a hand tangled in her hair, and he hates that he can’t see it. 

Remus hums. “Apparently your wife could show you how to do this better, too. Come now, are you going to let everyone in the room show you how pathetic you are?” 

James makes a high, keening noise, and starts to relax his throat, swallowing around Remus. It’s slow, and takes him a few minutes, but he does finally sink onto it all the way until his nose is buried in Remus’s curly hair. 

“There, you got it. Turns out you’re not completely shit at everything,” Remus says. He threads his fingers through James’s hair, scratching his scalp. “It’s a shame you can’t see the show, though. Sirius is holding Lily’s face with both of his hands and fucking her mouth. She’s got her fingers on her clit, and I think she might just come ag–” 

James pulls off, gasping from lack of air. He tries to turn to see, but Remus grips his hair tighter, wretching his head backward. “Is that all you can do? I thought you’d have a little bit of stamina, but apparently not. Try again.” 

Remus drags James’s head back to his cock, though this time, he doesn’t force James to swallow around him again, just holds his mouth on his cock. 

Sirius grunts behind him, and the sloppy fucking noises stop. “That’s enough. I want to come in your cunt, not your mouth.” 

“Okay,” Lily says, her voice hoarse and well fucked. 

Sirius laughs. “You sound incredible. And you’re better at that than your husband is.” 

“More practice,” Lily responds. 

“With that tiny peanut of his?” Sirius scoffs. “That hardly seems like practice.” 

Lily hums. “Sometimes I suck on my dildos just to have something real in my mouth.” 

Sirius laughs, haughty and belittling at the same time. “Well, my cock is always available for your practice. Any time you want. For now, though, I want to fuck you and make your husband watch. Get on your hands and knees, facing him.” 

“Sounds like you get a reprieve,” Remus says, tugging James’s hair again. He looks at Sirius. “Where do you want him?”

“Oh, I don’t think he’s done keeping your cock warm,” Sirius says. “Have him sit on your lap. He doesn’t get to come though.” 

Remus snorts. “Of course not. He hasn’t earned that.” He looks back down at James. “You heard him. Sit on my dick.” 

James gets off his knees, climbing into Remus’s lap. He turns around, squatting over Remus’s cock as Remus lines himself up, and James sinks down on it. He prepped himself earlier, but it’s quickly clear that he didn’t do it enough to take Remus. 

“Gods, you’re so tight,” Remus says. “All the way down now, then sit still, or I’m going to have to turn you over on the bed and fuck you, too.” 

James slips all the way down on him, and he’s so full. He leans back against Remus’s chest, with Remus’s arm coming around his stomach. “Good?” Remus asks quietly. James nods, words far away. 

“That was pathetic to watch,” Sirius says. James looks over at them. Lily is laying down on the bed, with her chest pressed to the mattress and her cheek pressed flat. Sirius kneels behind her, a bit of space between them, with his fingers disappearing inside of her. “We’ll do lessons on taking a cock next, I guess. Right now, I’m going to fuck your wife.” 

Sirius moves behind Lily, taking his own cock in his hands. He runs it through her lips for a moment before pushing in. James can see both of their faces go slack at the sensations, the pleasure and relief for both of them. Sirius palms Lily’s hip, giving her a moment to adjust before he starts fucking her. 

It’s a quick pace, neither of them wanting to drag this out much longer, and James can do nothing but watch as they both enjoy themselves with each other. Lily moves back onto her arms and legs, tits swinging with the force of every thrust Sirius makes against her. 

“Do you like watching them?” Remus asks in his ear. Remus’s hand is on James’s thigh now, not touching his cock, but gripping his thigh. “You just squeezed around me.” 

“Yes,” James says. “Very much.” 

“I can see why you would,” Sirius says, a bit out of breath as he fucks Lily. “You’re probably not used to seeing Lily look like she’s enjoying herself, are you?”

“No, sir,” James says. He watches Lily carefully, the glazed look that’s starting to take over her eyes. “She’s going to come again.” 

“I know,” Sirius says, “because I’m good at sex and I know how to please a woman. I hope you’re taking notes. Lily, come here.” 

Sirius pulls her up until her back is against his chest. She wraps a hand around his neck, bracing herself as she arches her back to continue taking him. Sirius’s hand rests against her stomach. “There, a better view for you.” 

“Thank you, sir,” James says. 

Sirius drags his fingers down her stomach and into the patch of hair between her legs. He spreads her open and finds the little nub that makes her gasp. “See, this is her clit. You have to stimulate the clit because most women can’t come without external stimulation.” 

“Don’t stop,” Lily moans, writhing against Sirius. 

Sirius turns his head into her neck, kissing her. “I would never. I’m here to make you feel good.” 

“You do,” Lily says. She inhales sharply, her whole body moving with it. “So good.” 

“I know,” Sirius says. He keeps rubbing her clit, and trails the other hand up to her breast.  “You’ve been so deprived.” He chuckles into her ear. “Do you remember what you said when James first asked you out, back in Hogwarts?”

Lily laughs, breathlessly. “A lot of swearing, as I recall.” 

“You told him that you would rather glue your cunt shut than sleep with him.” Sirius chuckles, kissing her cheek as Lily grins with her eyes closed. “You should have done it. Would have been better off than you are now.” 

“He might have still fit in if I did, though,” Lily counters. “Found a tiny hole to slip in.” 

Remus turns his face into James’s neck, inhaling as he drags his nose from James’s neck to his ear. “Are you watching them, James? Lily looks so turned on right now. Have you ever seen her look so sexually fulfilled?” 

James shakes his head. “No.” 

Remus tuts his tongue. “They’re right, aren’t they? She should have glued her cunt shut.” 

“Yeah,” James says. 

Lily gasps again, and it draws James’s attention back to her. Sirius’s fingers are still between her legs, and the other hand wrapped loosely around her neck. She’s flushed, her body trembling, and Sirius has gotten her so close to the edge without pushing her over. 

James wants to crawl over on his hands and knees to watch her come around Sirius’s cock. He can’t though, because Remus’s arm is around his waist holding him in place. He’s stuck, watching, as Sirius makes his wife come.

“You’re holding back, beautiful,” Sirius says. He nips at her shoulder. “Don’t. Let go for me. Come for me, and I’ll make you come again. I promise.”

Lily comes in Sirius’s arms, unwinding at the curl of his fingers, and James can feel from across the room how strong the orgasm is. She only stays upright because Sirius holds her up. 

Sirius lays her down on the bed again, without pulling out of her. Lily stretches her arms in front of her, arching her back and pushing back against him, as though she’s trying to get him to continue. 

Sirius slaps her arse. “Such an eager little slut. I can hardly blame you if all you’ve ever gotten is that peanut on your husband. I’d probably beg for cock too.” 

She whimpers and rubs back against him. “Sirius, please. I want to come again.” 

“Oh, we’re hardly done with you,” Sirius says. “How about we show you what it’s like to really be filled, though, hm? Remus, come over here and let’s give her a taste of what real men can do.” 

“You heard him,” Remus says, smacking James’s arse with his hand. “Off. It’s my turn to fuck your wife.” 

James stands up, though he nearly falls down again when Remus’s cockhead drags over his hole. When he manages to get up, Remus grabs his arse as he moves around James and toward the bed. 

James just stands there, looking at the three of them as Remus lays down with his back pressed against the headboard, until Sirius realizes he’s waiting. “Sit down, pet. You’re not useful for this.” 

Sirius waits until James sits, hands at his sides, before he finally pulls out of Lily. Her chest is pressed into the bed, arse up, giving Remus a clear view of her holes. Sirius turns to face him, one hand resting on her arse, and as best as James can tell from the wrong angle and her sudden twitches, Sirius is playing with her. 

“Which hole would you like?” Sirius asks. “I’ve had her cunt, so I don’t mind giving it up if you’d rather have it.” 

Remus tilts his head and considers for a moment. “Yeah, alright. I’ll take her cunt.” 

Sirius sits next to Remus, then pats his leg. “Come here, Lily. Why don’t you give Remus a little ride before we both take you?”

She pushes up on her arms and crawls over to them, breasts hanging low. When she’s finally facing them, James gets sight of her slit, spread from arse to clit, and how used and abused her flesh looks. 

It’s only for a moment, then she straddles Remus’s thighs. His hands come to her sides, resting on her hips, as she settles down onto his cock. He spreads his thighs a bit as she begins riding him. 

James can just see Remus’s face past Lily’s back as he watches her, making quick work of bouncing on his cock. His eyes are wide, aroused, unable to look away from Lily. 

Sirius reaches up and toys with her nipples, turning to Remus when she arches her back. “She’s so responsive, isn’t she?”

“Gorgeous,” Remus moans, his hands gripping her waist. He leans in, sucking her breast into his mouth. Lily leans her head back, moaning as she continues to ride him. “So pretty. Let’s ruin her.” 

James shifts on the floor, wishing he could join as they pile themselves on top of each other on the bed. Sirius lays down first, with Lily lining him up to her arse before sinking down onto his cock. Once she’s fully seated on him, she lays back against his chest, breathing deeply to get used to the feel of him while Sirius murmurs into her neck. James can’t hear what he says, but he can see Sirius’s hand slip down her stomach to find her clit. Lily writhes on top of him, then spreads her legs over his knees. 

Remus crawls across the bed toward them, between both of their thighs. Unfortunately, he blocks James’s view of Sirius’s cock buried inside of Lily when he does, and James can’t even see the moment that Remus pushes in. 

He knows it happens. He hears Lily and Sirius both moan as Remus presses inside, and James can only imagine that Remus’s sizable cock is stretching Lily and contracting Sirius’s space, and gods, he wishes he could see that. 

Suddenly, Sirius is glaring at James. “What are you doing? Do you have permission to do that?”

For a moment, James thinks he means watching them, and he whimpers. He doesn’t want to look away–right now, that might make him use his safeword. Only, Sirius’s eyes dart down to his cock, and it’s not until then that realizes that he’s been stroking his cock as he watches them. 

“Oh,” James says, pulling his hand away and looking at it dumbly. “I-I’m sorry, sir. I didn’t realize I was doing it.” 

Sirius tuts his tongue. “Of course you didn’t. You’re such a horny mutt that you can’t help yourself, can you? Then we’ll have to make sure you can’t disobey again, won't we?”

Sirius grabs his wand, laying on the bed an arm’s length away, right as Remus starts thrusting into Lily. James is immediately distracted by that, by the way Remus’s arse clenches as he thrusts in, the way Lily’s heels wrap around his back. He’s so focused on them that he forgets what Sirius was doing until his arms fly up. Tight ropes wrap around his wrists, keeping him locked in with his hands behind his head. 

James groans as he looks back at Sirius, who’s wearing a cocky smirk. “Behave, pet, and watch.” 

He has no choice but to obey as they both start fucking Lily with purpose. Sirius thrusts up into her arse in an alternating pattern to how Remus pushes into her pussy, and Lily clings to both of their arms at the overwhelming sensations. James watches her toes curl and her legs shake as they bring her to orgasm. 

They move, then, laying on their slides and flipping Lily around so that Sirius pushes into her pussy while Remus fucks her arse. James’s mouth drops open when Sirius hikes her leg up so that James can see everything. She’s stuffed so full, both of her holes stretched around them, and it takes everything in him not to crawl across the floor on his knees to lick all three of them at once, right there. 

Lily’s legs shake as they push her through another orgasm and keep going until both of them come buried inside of her. Sirius pulls out first, leaving Lily’s messy cunt dripping his spend, and when Remus pulls out as well, a glob of Sirius’s come pushes out of her. 

Sirius and Remus work together to lay Lily on her back, hands running up and down her body. It’s then that James sees her eyes are closed, lips parted and panting, and her body trembles with aftershocks. 

They grab her legs and drape one over each of their hips, leaving Lily splayed wide open and facing James. Sirius half sits up, looking at James, with his hand resting comfortably on Lily’s stomach. “We made a mess of your wife. Do you like seeing our come leaking out of her?”

The answer comes a little too quickly. “Yes, sir.” 

Sirius huffs at his eagerness. “I think you need to get over here and clean her up. If you can make her come while you do, I’ll let you finish too.” Lily whimpers and turns her head into Sirius’s shoulder. 

“Yes, sir.” James waits a moment, but Sirius just looks at him expectantly. “Will you untie my hands, sir?”

“No,” Sirius says. “You don’t need your hands. Use your tongue.” 

James bites his lip but doesn’t argue. He stands, thankful for his core workouts for the ease at which he can stand. It’s a bit harder laying down on the bed, leaving him little option but just to flop onto the bed between her legs. He has to awkwardly walk forward on his elbows until he’s face to… well, dripping pussy. 

James takes his time, starting with her arse and licking her in small strokes as he devours the taste of her and Remus there. It’s difficult, having to hold himself up by muscle alone. He doesn’t have the leverage to use his arms and hands, so it’s all he can do to keep himself in position to lick her. Lily starts twitching at his touch as he works his way up. The taste shifts from Remus to Sirius, and then James’s tongue dips into her. 

Lily moans loudly, and James looks up past her mound to see Remus and Sirius each kissing her neck as she moans and arches again. Their hands rest on her stomach, and other than the way they’re kissing her, those sounds belong entirely to James. 

He shuffles his way further up her body, licking and nipping at her until he finds her clit. He licks over it, then sucks the little bud into his mouth. Lily comes, almost instantly, a wash of her pleasure coating his chin as her legs tremble around him. James doesn’t let up until she slumps onto the mattress again, and even then continues to lick her until she’s clean. 

When James finishes, he presses a kiss over the hood of her clit, then rests with his cheek against her hip, panting. It doesn’t last long, though. There’s a scoff over him, and Sirius tugs a lock of his hair. “You’re not done. Get up, on your knees.” 

James laughs a little desperately, but he does as told. It’s a struggle, but he manages to work his way up to kneeling again, with his elbows above his head again, grinning with pride. 

The other three don’t move, laying together cuddled up on the mattress. Sirius spares him a glance. “You can finish yourself off.” 

James just stares at him, confused. He looks down at himself, cock jutting out from his hips, but his hands are still locked behind his head. “Um, how, sir?”

Remus snorts, leaning in against Lily. “Apparently, he needs instructions on how to come too.” 

Lily takes pity on him. “His hands. You’ve given him nothing to get off with.” 

Sirius huffs, kissing her cheek. “If he wanted it enough, he could find a way to get off.” Nevertheless, he waves his wand, and the ropes fall off his wrists. 

James wastes no time, grabbing his cock in his hand and stroking roughly. He groans and brings his other hand up to squeeze his balls. It doesn’t take long. He’s been so turned on watching and being degraded that he feels his balls tighten after just a handful of strokes. He comes messily over Lily’s stomach. 

As soon as he finishes, there are hands on him, guiding him down. He’s laid down between them, facing Lily and with Sirius at his back, and all of them are touching him. 

“You did so good, love,” Lily says, pressing kisses over his cheeks. 

“Perfect little slut,” Remus says, his arm resting across Lily’s waist and his hands on James’s hip. 

Sirius kisses his shoulder, soft fingers stroking up and down his arm and side. “You were perfect. Was it what you wanted?”

James turns his head, catching Sirius’s lips in a kiss. “It was exactly what I wanted.” 

Sirius kisses him back. “Good. You’re surprisingly fun to degrade.” 

James laughs. “Thank you, sir?” The word comes out like a question. 

Lily snorts. “If you keep calling him that, it’s going to go to his head.” 

“It already has,” Remus laughs. “He’s going to be insufferable.” 

“Keep calling me that,” Sirius says, kissing James’s shoulder. “It’s going to give me so many good ideas for next time.” 

“There’s going to be a next time?” James asks, hopefully. He looks at Lily and Remus first, laying across from him. 

Lily leans in and kisses him gently. “I want to if you do, love.” 

Remus leans his head against his elbow, propping himself up to look at James over Lily’s shoulder. “Oh, definitely. I think we went too easy on you this time.” 

James glances over his shoulder toward Sirius, who kisses his cheek. “There’s absolutely going to be a next time.” 

James grins and settles between them. “I can’t wait.”
