Chapter Text
Bucky whined as Grant carried him into the Tower after the Quinjet landed on the pad. Tony looked up from his coffee as Grant beelined for the elevator. “Hey, where are you going?”
“Our floor. Need to take care of… Bucky.” The pause was typical for Grant as he tried to remember what to call Bucky instead of just calling him his handler, because that just angered the other man.
“But…”
“Steve apparently okayed this…” Grant paused moving for a moment to speak up in addition to what Natasha had said.
“Steve is holding the Asset back.” Grant’s voice was rough as Bucky gave another short whine, clinging tighter to Grant.
“Are… wait, are you not the Asset!?” Tony asked, frowning.
“No. I’m Grant. The Asset is someone else entirely.”
“Sir, I believe that Grant suffers from Dissociative Identity Disorder and-” JARVIS’ voice petered out as Grant stepped into the elevator and hit the button for their floor. His steps were quick as he strode into the apartment, but had to stop, looking between the den and the bedroom Bucky slept in.
“Bucky…” Grant grumbled, already feeling too inexperienced to be able to do this.
“Grant?” Bucky questioned, looking up at him, eyes bleary from the chemicals that were coursing through his body.
“Bedroom or Den?”
“Den… please…” Grant shifted to put Bucky down and as the Omega let go, Bucky crawled in, getting his scent on everything in there. Grant sat down on his ass, quickly tugging his laces until they were undone, and tugged off, placed next to each other just outside of the den. He heard movement and ducked his head back as two other boots came sailing out of the den he had constructed.
“Grant…!” Bucky whined as he soon pitched his shirt out of the den though it didn’t go as far as his boots.
“I’m coming…” Grant disarmed and shoved his weapons in range of his hands under the blankets of the den, and then got his leathers off except for his pants, and crawled in after Bucky, shifting to lay next to him. Settled in facing each other, Bucky pressed his face into Grant’s scent gland on his throat, the den quickly filling with the scent of oranges and cloves as both of their arousal scents flooded the small area.
Bucky licked against Grant’s skin, tasting his scent like he was eating it. “Fuck you taste… different… smell sorta the same… but cloves… that’s all you…” Bucky moaned as Grant’s arms wrapped around him and held him tight.
“You smell like… oranges and peaches Bucky…” He nuzzled in, and sighed softly, feeling the way Bucky kept shifting against him. “What… what do I do?” Grant whispered.
“Whatever feels right…” Bucky replied, before Grant leaned down and kissed the corner of Bucky’s mouth, hands ghosting against Bucky’s flushed skin. It was causing him to shudder and shake, and Grant loved every moment of it. Loved knowing that this man was quaking for him. Grant leaned in, burying his face into Bucky’s scent gland in his neck, he inhaled deeply and groaned softly.
Bucky shifted against the hard length Grant sported, and whined, desperate for relief. Grant was careful as he worked Bucky’s pants off his legs and soon had the man spread out underneath him. He swallowed hard, mouth watering, wanting to get his tongue against that wet heat. But he was allowed to do this, Bucky had said so. So he kissed his way down Bucky’s body, taking a small amount of time to kiss and give attention to Bucky’s nipples, before he was continuing down to be buried down between Bucky’s thighs. He inhaled softly but deeply, and licked over his hole, eyes closing in pleasure as he tasted Bucky’s slick, and how sweet it was. Shivering a little bit, he wrapped his arms around Bucky’s thighs, pressed them tight against his cheeks and gripped them tightly with his hands. He was certain he was leaving marks, but Bucky’s hands were in his hair, tugging on the long strands, and moaning wantonly as if he were enjoying it.
Grant was trying to ignore how terrified he was that this wasn’t going to go well and that he was going to fuck this up. Bucky was moaning for him, clinging to him, thrusting his hips up into Grant’s mouth.
“Hey big guy.” Grant glanced over at the other blonde and furrowed his eyebrows, as it took a moment to remember who he was.
“Clint… Right?”
The beta’s lips spread in a wide smile. “Yup. Look, not gonna put things in your head just yet, but just in case Bucky and you wind up… doing the thing and mating… You’re gonna want condoms.”
Grant stared at Clint confused, eyebrows still furrowed.
“You know… sex?”
Clint watched as Grant suddenly caught on. “But… isn’t that the point of mating? Why would I…”
Clint shook his head. “Not this time, big guy. You’d want to make sure he was aware and even ready for the possibility of children. So, condoms. Here.” Clint shoved a box of them into one of the pouches on Grant’s belt. “You’ll pull one of those on right to the base and then you’re good to go to do whatever it is you and Cap are gonna get up to. It’ll protect your knot too… So… make sure you put it on. Don’t be dumb.”
With Clint’s warnings clear in his head, despite the heady scent and taste of Bucky in his mouth, he pulled the condoms out of his pouch and pulled back from Bucky, despite his pleading whine. It was hard to focus on what he was doing, feeling the pressure and feelings he had never experienced before, even in his dreams. This was completely new territory for Grant, and he wanted nothing more than to make sure that he pleased the omega below him. The only person that mattered right now was Bucky…
He quickly read how to put the condom on, and got the latex on, and settled over where his knot was going to expand.
“Grant… please…” Bucky’s voice was high pitched, whining and desperate. And Grant couldn’t hold back from giving the omega what he wanted any more than he could stop breathing. Shifting closer, knowing that he was going to flounder his way through this, his fingers sought out Bucky’s tight wet heat, slowly working his way inside of the man, stretching him out to what he could guess was a good size before he removed his fingers and slicked up his cock. His hands were shaking, which was a novel experience for Grant, who never wavered ever.
Drawing in a breath, he slowly let it out, trying not to get too far into his own head about this. He held the base of his cock, poised between Bucky’s spread thighs as the man writhed. Everything about this was nerve wracking, what if he did it wrong? What if he couldn’t make Bucky cum? What if he did everything terribly? Too hard? Not hard enough? His instincts were fighting each other, and he was flying blind with absolutely no idea what he was doing.
Grant felt hands gently cup his cheeks and he brought his eyes up to look at Bucky’s lust filled dark eyes. “G-grant?”
“I’m sorry… I’m nervous. Don’t know what I’m doing…” He whispered, before Bucky’s eyebrows furrowed.
“Oh… sweet alpha, roll over for me.” He quietly ordered, and they soon shifted their positions, and Bucky swung his legs over Grant’s thighs, helping get that large alpha cock inside of himself. Bucky started to ride Grant, hands braced on either side of Grant’s head. Grant’s hands were on his hips, helping hold him steady. Even through the condom, Grant could feel how hot, wet and tight Bucky was as he clung to him. A feeling he didn’t understand was building quickly and it was making him feel a little panicky.
“B-bucky…” He groaned, hands gripping tighter on his hips.
“It’s okay… Give it to me. You’re doing so good…” Bucky encouraged, sweating and panting as he chased his own pleasure, using Grant like a very well fleshed dildo. His eyes were glazed, but looked at Grant like the Alpha had hung the sun, moon and stars in the sky. Grant shifted his feet, and braced himself as he started to help Bucky, thrusting up into him, no longer just a passive participant. He was starting to understand how this was supposed to work, and he tried to keep up with a pace that seemed to satisfy the omega riding him.
When he stopped focusing on what he was feeling and trying to figure out what it all meant, Grant was able to focus just on Bucky, feeling his knot starting to swell and catch around Bucky’s rim. Bucky was whining as he chased the sensations, and all too soon, Grant felt his knot fully inflate and locked them together. Bucky reached between them, stroking himself as he chased his own satisfaction. Grant was covered in Bucky’s cum, and couldn’t stop himself from swiping up a little bit with his fingers before he pressed it between his own lips and tasted the salty spend on his tongue. Swallowing it down, Bucky was shuddering over top of him, coming down from his own orgasm.
With nervous fingers, Grant reached up, sliding his hand to cup Bucky’s cheek, watching the omega turn his face into the touch. “You’re so… beautiful.” He whispered up at Bucky who smiled back at him.
“You don’t know what you’re doing do you?” Bucky asked softly, but it wasn’t meant to be unkind.
“N-no. Steve’s still… subduing the Asset… What can I do to be better?”
“I’ll guide you as much as I can… Promise.”
The next four days were a blur of sex, caring and helping keep Bucky hydrated. Bucky’s needs took priority and Grant did his absolute best to make sure that he did everything that Bucky asked of him.
Grant’s eyes closed and the exhaustion he felt let him slide back from the front of his mind. When his eyes opened again, they were blue, and Steve turned to look over at Bucky, smiling softly.
“Hello Omega mine…” He whispered, brushing Bucky’s sweaty bangs back from his face.
“Steve…” Bucky smiled tiredly up at his alpha.
“How did he do?”
“Inexperienced, but… He did well. You’d be proud.” Bucky leaned up, kissing Steve soft and slow.
“I’m sorry I couldn’t be there to help you sweetheart.” Steve murmured against his lips.
Bucky didn’t respond, because one way would be agreeing and diminishing his budding relationship with Grant, and the other would be saying he didn’t need Steve because he had Grant. Neither was an acceptable answer, and Bucky wasn’t going to do that to either of them.
“Did you deal with the Asset?”
“Sort of. Got him locked back away again… But… If we have a way to get rid of him? It would make life a lot easier.” Steve laid back on his back, with Bucky curled against his side, his arm wrapped around his shoulders, and gently drawing designs on his shoulder.
“Would that… Get rid of Grant?”
“I don’t know sweet omega. I think perhaps we’ll need to talk to someone who knows more than I do. Do you want him to stick around?” Bucky didn’t answer right away, and rubbed his face against Steve’s chest.
“I’m not sure how to answer that. On one hand, he’s part of you… and as long as you would wind up taking on some of him so that he isn’t entirely gone… I think I might be okay with it… I mean… It’s been almost a year Steve… I’ve had almost a year growing with him, teaching him, and I just… I think I might miss him, not that there’s anything wrong with you!” He was hasty to state as he leaned up so that he could look Steve in the eyes, and see the amusement in his mate’s eyes.
“I know what you mean… I’ve liked what I’ve seen with you and him interacting.” Steve replied with a smile at his mate, watching him relax again. He held his hand up, looking at his fingers. “But… Can you be okay with these hands touching you sweetheart? What if it was just Grant? His hands are… clean. Cleaner than mine.”
Bucky slid his hand up Steve’s arm until their palms were pressed together. “Do you think my hands are dirty?” He asked.
“No. Not at all. You’ve done everything for good.”
“But I didn’t. Hydra was so deep in SHIELD that I did things for them that I definitely wish I hadn’t. I’ve killed people for Hydra when they were hiding in SHIELD. Am I any better than you?” Bucky snuggled in closer to Steve and sighed softly.
“Sweetheart, you are all that is good and sweet. Your hands are clean. Well… cleaner than mine. Not as clean as Grant’s, but cleaner than mine.” Steve leaned his cheek against the top of Bucky’s head and snuggled in to enjoy the post-coital haze.
Bucky wound up calling in his favour from T’Chaka to get Steve/Grant the help they need. He knew that the technology in Wakanda was far superior to what was offered anywhere else, including within Avengers Tower. It was a lengthy process to undo that much mental coding, and Bucky was still needed to be Captain America during that time. But he had a free pass to go back and forth as needed.
For nearly three months, the medical bay worked non-stop to help bring Steve freedom from the code words, to save him from Hydra. And while that was happening, they got a doctor specialized in Dissociative disorders, that could help them with solutions. Although it appeared that as Steve’s mind continued to heal, the more that him and Grant melded together. It was an unprecedented happening, and while they were happy with the result, they also knew that this was never going to be able to be replicated.
While Wakandan Doctors worked to heal Steve, Bucky and the other Avengers worked tirelessly with law agencies to get Steve’s Winter Soldier activities expunged and fought for him to not have to pay for the crimes he committed while under Hydra’s control. Once it was all said and done, Steve was free, and had parts of him that were Grant and parts that were himself from the 40’s.
Bucky sat heavily on the couch, tilting his head back, giving a small sigh of tiredness. It had been a day full of conferences, and court appearances. A damp cloth is laid over his eyes, and Bucky smiles.
“How does it feel, omega mine, to know that you’re Captain America, officially longer than me?”
“Honestly? I hate it. Want it back?” Bucky grouched softly.
“No. I’m happy being Nomad, and standing at your back. But it’s nice to see that Captain America is held by a man who deserved it so much more than I ever did. You were always a better man than me. You only fought when you had to.” Steve pressed a soft kiss to his lips before he moved to sit on the couch next to him. Bucky shifted to lay down on the couch, with his head on Steve’s lap, enjoying the pampering that was being given to him. And he knew that no matter what, he was going to have Steve, with his mild mannered Grant side and his righteous Steve side. The Avengers accepted Steve as their head alpha, although all decisions were deferred to Bucky, since this was his pack, and all of them had congregated to Bucky as a central figure.
“We’re still on for Pack night tonight?” Steve asked, brushing loving fingers through Bucky’s hair.
“Mhmm. After I have a nap, we’ll go down and start organizing food. Nap first though.” Bucky mumbled, letting himself drift, safe in the knowledge that Steve was here.
