Chapter Text
The idea was intoxicating to him. Bucky spent over a week going over what he had learned about Steve and Y/N's relationship, and their invitation to join them. Thinking about finally exploring the feelings he had harbored since his teens, knowing that Steve may have felt it all those years as well; it made him slightly dizzy. And then there was Y/N, a woman he not only found very attractive, but he also cared a great deal for her. How could he possibly wrap his head around the fact that these two seemed to want him in ways he had only dreamed about.
Dreams that confused as much as they aroused him.
He knew that he was sending mixed signals to them. Sometimes he would act as if they conversation had never taken place, like nothing had changed. Others, he would be so deep into his fantasy that just being in the same room as them was overwhelming and he would flee as subtly as possible. He could tell Steve just figured he wasn't interested. The easy affection between them began to feel a little strained, as if he wasn't sure it crossed some kind of line or not.
One afternoon he was walking to the gym with plans on working off his sexual frustration, still trying to decide what he was going to do, when he heard the two of them talking. Out of curiosity he followed the sounds of their voices, finding Steve and Y/N in what appeared to be an argument.
“Y/N, you don't need to leave, it's all gonna blow over.” Leave? Bucky felt his stomach drop.
“It's not like I would be gone for good, but maybe it's for the best if I just go visit my family for a week or so. Things changed that night, Steve, and it's my fault.”
“I'm the one that suggested that whole thing! I could have left or safe worded at any time, but I wanted to push myself.”
“But you didn't invite your best friend into our bedroom! I did.” Steve sighed and cupped her face in his hand, rubbing his thumb over her cheek.
“Maybe that wasn't the best time or place to do it, but we both know it was going to happen sooner or later.”
“I feel like he can barely look at me any more, Steve.” Y/N said sadly. “He probably thinks I'm twisted, and just too nice to come out and say it.”
“And what would that make me, then?” Steve replied. Bucky couldn't take it anymore. He stepped around the corner. Y/N let out a little gasp and pulled away from Steve.
“Bucky-”
“I don't think you're twisted.” He blurted out. “Either of you.” Steve visibly relaxed. “You don't have to leave. Please don't leave.” He took a few steps towards them.
“I don't want you to be uncomfortable.” She said.
“I'm not. I swear, just…” He trailed off and looked down at his feet. He could feel the tips of his ears burn. “I wanted to, want to say yes.” Steve opened his mouth to say something when the three of them heard talking and laughter coming towards them.
“We should take this somewhere else.” Steve said, taking Y/N's hand and motioning for Bucky to follow. The three of them went to Steve and Y/N's rooms. Bucky started to pace while Steve sat down and pulled her onto his lap.
“You want to accept.” She said calmly after a few moments of silence. “I'm sensing a 'but'.”
“It's not really… I don't know.” Bucky stopped moving and looked over at the couple. “I mean, is this a one time deal? I don't want to come between you two.” He watched them share a look, like they were having a silent conversation. Steve smiled and nodded at her. They stood and Y/N took Bucky's hands.
“This doesn't have to be more complicated than the three of us want to have some fun,” she told him. “However, I would like to try something real quick.” She stepped closer to him. Bucky could smell her perfume and he swallowed hard. Her hand ran up his chest and rested on his shoulder. “Okay?” She asked. Bucky let out a shaky exhale and nodded. Y/N went up on her tip toes and gently kissed the corner of his mouth. She pulled back, as if to give him a chance to change his mind. He briefly looked over at Steve, wondering if he was really all right with it. Steve's pupils were lust blown watching the two of them. Bucky shifted his eyes back to Y/N. “Still okay?” She whispered. Another nod. This time she kissed him fully on the mouth.
He couldn't help the moan that left his throat and his hands went around her waist. All of her touches were delicate, but his fingers dug into her skin as if he were about to fall off the edge. Memories of kissing pretty girls somehow both flooded his mind, but also blurred in comparison to the woman currently kissing him senseless. And suddenly, the contact was broken. Bucky willed his eyes to open, to see her smiling face.
“Wow.” He breathed. Y/N chuckled lightly and turned to Steve. When she saw his hand palming over his jeans she tsked and grabbed him by his shirt.
“Did I tell you you could touch?” Her tone was teasing, with an edge that sent a shiver through both men. She tugged Steve closer and gave them both a significant look. “Your turn, if you're still on board?” She directed the question at Bucky.
“Yes.” He croaked out. Y/N cupped the back of their heads and guided their faces towards each other. Steve hesitated a bit, searching Bucky's face for any signs of aversion. When he saw none, he relaxed and let the kiss happen. The first thing Bucky thought was that it was different than kissing Y/N or any other woman, but it was still enjoyable. He could feel her fingers work through his hair, nails scratching at the sensitive skin at the nape of his neck. Steve sighed against his lips, ran his tongue over his mouth in a playful manner before pulling away. The three of them just stood together for a moment.
“Did that feel like something any of us want to do only once?” Y/N asked.
“No.” Bucky said instantly. It was his first taste, but he was already hooked. He licked his lips and imagined he could still taste the two of them.
“Definitely not.” Steve said, still staring at Bucky. Y/N nudged him.
“Maybe I'm the third wheel here.” She said, jokingly. Steve grinned at her and laced his fingers with hers.
“I think we all know you're the driver.” Her eyes darkened and she reached out to take Bucky's hand.
“We should sit down and talk about a few things before this goes any further,” she said. “Is that okay with you, Buck?” He nodded and squeezed her hand.
She walked him through how everything worked between Steve and her. The rules, put in place for safety, and to make sure everyone found pleasure and enjoyment; how hard limits were never to be ignored or pushed.
“I know Steve mentioned that we talked about breath play at one point,” she said, with a serious look on her face. “I found the idea appealing, but in reality I hated it. It scared the hell out of me.” Steve rubbed her shoulders.
“So that would be one of your 'hard limits'.” Bucky said, and looked over at his friend. “Do you have any?” Steve blushed.
“I wasn't a huge fan of breath play either, but not so far.” Bucky learned seemed to learn more and more about his best friend every day.
“We tread lightly with anything new,” Y/N told him. “Start small and build up to something more intense.”
“I'm new.” Bucky said quietly. She smiled at him in a way that made him want to squirm.
“You are.” She stood up and nudged his legs open until she could stand between them. “That means I'm not going to fuck you… yet.” She stroked his hair and chuckled at the disappointment on his face. “We can still play. If you want.”
“Ye-yes. I want to.”
“Aw, do I make you nervous, Bucky?” She teased. “I think I like that. Now, if Stevie is on board with all this...” She shot him a look over her shoulder.
“Very much so.” Steve replied.
“Excellent.” She gripped Bucky's hair and gently but firmly pulled. He let out a low groan and met her eyes. “I'm going to leave the two of you alone for five minutes. You will both strip down to your underwear. When I come back, you will both be kneeling. Steve will show you the correct way. Do you understand?”
“Yes.” She gave his hair a sharp tug.
“Yes?”
“Yes Ma'am.”
“What is your color?”
“G-green. Ma'am.” Her lips curved.
“Good boy.” The praise sent a shiver through him.
When she returned both men were kneeling with their arms held behind their backs, heads bowed. They heard her soft footsteps as she circled them. Bucky could see her bare legs but he resisted looking up to see if she was naked, remembering Steve's warning to remain still until she gave further instruction. Y/N finally stopped between them.
“I find myself a little overwhelmed. Each of you are gorgeous on your own, but the two of you like this? Exquisite.” She touched her index fingers to their chins and encouraged them to look up at her. Bucky let out a groan before he could stop himself. She wore a short silk robe so delicate and sheer he could see her breasts through it. A pair of lace panties was her only other clothing. “Do you like it? It was a birthday gift from Stevie, although I think it was as much for him as it was for me.” Bucky only swallowed the lump in his throat and stared at her in response. She smiled. “I'll take that impressive tent in your skivvies as a 'yes'.” Bucky blushed and shifted on his knees. “I think it's about time we took this into the bedroom, follow me.” She walked away and the men scrambled to get to their feet.
The bed was stripped down to the fitted sheet, and the lighting was dimmed. Bucky smelled the soft fragrance of lavender in the air and noticed a few candles burning on the dresser. Y/N dragged her nails down his chest, pulling another sound from his lips.
“In here, you may both make as much noise as you wish,” she said. “I want to hear that you're enjoying yourselves.” She went to Steve and pulled him down for a sizzling kiss, all tongues and teeth. “Take 'em off, Stevie. And get on the bed.”
“Yes, Ma'am.” Steve rid himself of his boxer briefs and lay down on the mattress, propping himself up on his elbows so he could watch her and Bucky. His cock was fully hard, curling up towards his abdomen but he made no move to touch himself. Y/N took Bucky's human hand and guided it down the front of her panties.
“Do you feel that,” she murmured. “How wet I am for my good boys?” She used his fingers to circle her clit. “I could just use you like this to get off. Leave you both throbbing and aching, desperate to be touched, to be allowed to come.” Her breath stuttered and she stilled his hand, pulling it out of her underwear. Bucky rubbed his fingers together, feeling her wetness. “Tell me, Bucky. Do you like to watch?” She nipped at his ear.
“Watch?” The feeling of her teeth on his neck made it difficult for him to think.
“Stevie wants you to watch us. It's one of his little fantasies, isn't that right?”
“God yes,” Steve groaned and ran one of his hands over his hip. “Please touch me.” He whined.
“Soon, pet.” Y/N promised. “I think it would be perfect to ease you into all of this.” She told Bucky. “I'm going to do all the things that drive Stevie absolutely crazy, while you stand and watch. Maybe you'll get some ideas.” Bucky bit his lip and looked away. “No, don't do that. Communication, remember?” She said seriously.
“Can I… Touch myself while I watch?” He whispered. Y/N smirked.
“Since you asked nicely, you may.” She cupped his erection and squeeze gently. “But don't you dare make yourself come. I want my lips around your cock before that happens.” She snapped the waistband of his boxers. “Take these off. If I look over at you I want a good view.” Y/N climbed onto the bed and ran her hands up Steve's legs.
“Fuck.” Bucky muttered when he finally wrapped his fingers around his dick.
“Is this everything you dreamed it would be so far?” Y/N purred, peppering Steve's skin with kisses.
“It's so much better,” he groaned. “I love you so fucking much.”
“My sweet exhibitionist,” she bit down on one of his nipples. “Did you know your best friend was such a slut, Bucky? His cock is already leaking and I haven't even touched it.” Her hand hovered over it. “Should I stroke him? Let him fuck into my hand?” Bucky only moaned in reply, trying to keep his pace slow so he wouldn't explode already. “Oh, that sounds like a no to me, Stevie.”
“Please.”
“I have plans for this,” she ran a single finger up and down his shaft. “I want you writhing and begging.” She leaned over and opened a nightstand drawer, pulling out a bottle of lubricant. “Will you be able to contain yourself if I finger you or do you need a cock ring?” Steve shook his head.
“I can handle it.”
“I've trained you well. Bucky? Come over here and sit on the bed with us.” He sat down and leaned against the headboard. Y/N slicked up her fingers and circled Steve's hole. “This is what we did before Steve slipped the plug in that night.” She told Bucky and slid one finger into Steve.
“Oh fuck, babe.” Steve sighed.
“I opened him up, nice and slow. I don't know how he got his pants on, I thought he would burst.” Bucky felt his orgasm coming and stopped stroking himself, squeezing the base of his dick. “And when we came back here, I put on a strap on and fucked him. Are you familiar with those?” She added another finger.
“I-I've seen them before. In porn.” He started to stroke his cock again.
“Aren't you full of surprises,” she laughed. “Give a man internet access and he will figure out how to jerk off to porn.”
“I need more.” Steve moaned, pushing down on her fingers.
“You want me to stop teasing?” She crooked her fingers and Steve arched off the mattress with a jolt, his cock drooling over his stomach. “Does that feel good, pet?” Y/N cooed.
“It f-feels amazing. Oh shiiiiit, Y/N please!”
“Please, what? Fuck you with my fingers?” She rubbed firmly over his prostate. Bucky watched him struggle to keep his hands off his dick. “Don't you dare,” Y/N warned, but her tone was playful. “Isn't he beautiful, Bucky?” Her eyes devoured the sight in front of her. “I know how to keep him on the edge for hours. I hope I'll learn the same for you.” The idea somehow made him even harder and he felt his head swim a little. Bucky got lost in the image of himself, dripping and hard with her fingers buried in his ass and her mouth wrapped around his cock. It was only her reaching out and grabbing his wrist that stopped him before he came.
“Fucking hell,” he panted. “That was close, sorry.”
“No need to apologize, you're learning. But you may not touch yourself again.” His dick twitched.
“Please?” He asked weakly.
“Don't worry, I told you I want you in my mouth. You'll come when I suck you off.”
“She's amazing, Buck.” Steve rolled his head to look at Bucky with hazy eyes. “Believe me, it's worth the wait-” he broke off with a loud cry. “Fuck! Y/N!”
“Do you want a plug before I ride you, Stevie? Do you want your ass full while I fuck myself on your dick?”
“Yes!” She slowly pulled her fingers out of him and left them for a moment. Steve tried to catch his breath as he looked over at Bucky again. Both men were flushed and panting.
“You've been so good, Stevie. I have your favorite.” She came back completely naked and wasted no time pushing the black rubber plug into his hole. When it was fully seated in him she straddled his hips and rubbed the tip of his dick over her slick entrance. “Watch me take his cock, Bucky,” she moaned softly. “Watch him stretch my pussy open.” She sank down onto Steve, letting her head fall back and let out a blissful sigh.
“Shit.” He muttered, watching her ride his best friend's dick.
“Come over to this side of the bed,” she panted. “I want that perfect cock in my mouth.” Bucky stood on shaky legs and did as he was told. When her hand wrapped around him he practically growled. When she took him into her warm, wet mouth, his eyes rolled back into his head. Grunts filled the thick air of the room. Every time Y/N moaned the vibrations added to Bucky's pleasure.
“I'm getting close, Y/N!” He gasped. She pulled away from him with an obscene pop.
“I want you both to come.” She took him back in her mouth. He felt her tongue caress the sensitive spot under the head and she took his balls into her hand, rolling and squeezing them gently. His knees nearly buckled. Steve was thrusting up into her as she rode him, chasing his own end.
“Fuck, I'm gonna- I'm coming!” Steve yelled. Y/N slammed her hips down and he went rigid. She swallowed around Bucky and he too fell off the edge, shooting down her throat with a long groan. She smiled around him, sucking and licking him through his release and the aftershocks until he was too sensitive and pulled away.
“You're both absolutely stunning when you come.” She said with a wicked grin. Bucky sat down on the bed before he collapsed.
“You didn't-?”
“Not yet,” she purred. Y/N got off of Steve and dipped two fingers into her dripping pussy. “You both get to clean me up and finish the job. I want to see how well you work as a team.” She laid back and opened her legs. Steve's seed was slowly flowing out of her. Steve didn't hesitate and began to lap at her labia. Bucky was slower to move, but he nudged Steve over so he could get his mouth on her sex. His and Steve's tongues moved over her, occasionally bumping together in a filthy parody of a kiss. Her moans grew louder, urging them to continue. Bucky found her clit and gently sucked on it, swirling his tongue over the bundle of nerves. “Oh fu-uck! Right there, don't you dare fucking stop!” They licked and sucked at her, not letting up until she exploded and her thighs trembled from over stimulation. She pushed herself up on her elbows and smiled lazily at them. “Wow. You boys sure you haven't done this before?”
“Pretty sure,” Steve replied with his own grin. “You look so gorgeous and fucked out right now.” He pressed a kiss to the inside of her thigh.
“I can say the same of you two. How did I get so lucky?” Bucky grabbed her hand and pulled her up so he could kiss her. His chin was still wet with her release.
“I can stay?” He asked quietly when he pulled away.
“Oh honey, we're keeping you.” She told him. “I'm not giving up either one of my boys.” Bucky smiled.
“I think I like being yours.” Y/N wiped at his face with her thumb.
“We need a shower.” Steve scooped her into his arms and she shrieked in surprise before dissolving into giggles.
“You heard the lady, Buck.” He began carrying her towards the bathroom. Bucky grinned and followed, joining in Y/N's laughter.
