If there was one thing that John Walker had in abundance it was shame. It didn’t matter where he was or what was happening, even if he thought he was free from it, it would creep up on him and make his muscles go tense and his stomach feel sick.
That’s why when The Thunderbolts had their stand off with Bob—well, Sentry—at the time, and John had felt that familiar sensation of his stomach sinking, he hadn’t thought it to be the best time to bring it up. Actually, John never wanted to bring that day back up with anyone, because the exact thing that had gotten him to feel that way was so humiliating and so unprofessional that he didn’t think anyone would take him seriously if they knew.
John played that day over and over in his head. The day that they’d gone to get Bob back, when they had all hoped that the man would come back to them while they waited with open arms and wouldn’t have listened to the shit that Valentina was trying to convince him of.
So, when Valentina had announced ‘The Sentry’ and Bob had shown up in front of them with blond hair and that ridiculous fucking suit, John hadn’t been able to look away.
But those words that he’d uttered as he dismissed John...
You can call me Sentry.
John had tried his hardest to hold his gaze, his eyes fixed on the other man, but then Bob had looked over at him and John was certain he was a pretty weak man because he’s never looked away from a person faster.
Now, Bob could be a pretty clueless guy when it came to people’s affections for him, but if there was one thing that John had figured out about him was that underestimating him was not an option because it would only come back and bite him in the ass later. So, John was pretty sure Bob knew how he felt about the Sentry suit, and how it made him feel when he exhibited the strength he kept hidden away.
John was almost certain, had it just been the pair of them in that room and no life or death situation was present that he might have mustered up enough courage to actually beg Sentry to fuck him against a wall. Fuck. He wanted that.
He was laying on his bed lazily, one of the old Hollywood movies that he liked to use as background noise playing softly in the room as he scrolled through his phone—not that he was paying attention to what he was looking at. He was far too busy thinking about Bob. Bob with that stupid suit and a sure confidence that would have John falling to his knees for him.
Valentina had described Sentry as a God, he knew, and she hadn’t been wrong about that. At least not in John’s eyes anyway. If the Sentry was a God then John would fucking worship him like a God.
Fuck.
There was that mind numbing shame again creeping its way inside him. This was dumb. John was a fucking pervert and Bob definitely hadn’t realised how he’d reacted to Sentry, end of story. He didn’t want to think about this anymore. He was only driving himself slowly insane.
Does Bob even still have the suit?
No. Nope. That’s it. John is truly fucked. He needed to get up and do something before his brain filled even further with thoughts of Bob in his suit and his brain became fully uncooperative.
John let out a heavy sigh and pushed himself off the bed, finding the remote to turn the TV off before he left his room and headed the team’s shared kitchen. He wasn’t the best cook in the world but Olivia had seemed to like his cooking well enough and then when he moved to the tower and found that his teammates’ standards were even lower than he expected he kind of became everyone’s personal chef.
He wasn’t overly hungry but he figured it was probably best to give his mind something to focus on that was better than the alternative. John hummed a soft tune as he busied himself. Most of the others had solo missions they were attending to which meant that it was probably only him and Bob in the tower at the moment, but now that John thought about it, he had no idea where Bob was. Normally, he’d be reading a book or something on the couch, but he was nowhere to be seen.
John knew he shouldn’t get worried over something simple like that, the man was probably just spending some time alone in his room, but there was something gnawing at him that was telling him he should go and check on Bob.
He left the soup he was making to simmer as he made his way to Bob’s room. There was still a certain amount of caution that he used when approaching Bob’s space, because even if Bob was okay today that didn’t mean he was going to be okay tomorrow and John didn’t want to invade his personal space or go somewhere he wasn’t welcome.
Being a few feet away from the door was all it took for John’s thoughts to spiral. Him and Bob hadn’t really got along at first, then the whole Sentry thing happened and John got a real look at what Bob was capable of. After that, the pair had kind of developed this weird mutual respect for one another, almost friends but not quite, where they would purposely piss each other off or taunt one another, sometimes even flirt a little.
And then John’s brain had to go and make it weird.
He knocked on the door a couple times before Bob finally answered, blinking at John in confusion like he hadn’t expected John to show up at his door, and John’s brain short circuits.
Bob is in the Sentry suit.
He parted his lips, about to ask Bob if everything was okay but found that his mouth had become incredibly dry all of a sudden. John gaped at him, stunned. Bob grasps him by the shirt and pulls him inside, closing the door.
“Bobby, what are you—”
“I know—it’s stupid, right?”, Bob says, cutting him off, and honestly John doesn’t knows how to respond to that because how the fuck can Bob think he looks stupid like this? He doesn’t say it, but John thinks he looks hot as hell, even more so that he’s no longer sporting the blond hair to go with it.
“No...no, not at all, Bobby. You look...great—but eh...what’s it for?”, he asks, trying to stay in control of his own thoughts as much as possible as he takes in the sight in front of him. The suit looks amazing on him. It hugs his body just right and John feels his eyes roaming.
“I don’t know...I overheard Valentina talking to Yelena about some kind of party or fundraiser—one or the other—and she said to her how she’d love for me to be there—”
“And you’re doing what Valentina wants?”, John questions, suddenly feeling a surge of possessiveness running through him, but he pushes it down in favour of having a meaningful conversation with Bob.
“It’s not that, exactly...”, Bob says, his voice soft, “I kinda want to go actually. I know it might sound dumb, but I’ve never been to one of those things and you guys always seem to have a decent time—and sure I don’t really go outside—actually I’m kind of scared of going outside but I just thought that maybe if I stayed with you it would be okay...”
“That’s great, Bobby. I mean, don’t get me wrong, I’m happy that you’re getting out and all...but why bother with the Sentry suit? Why not just wear a regular suit or something?”, John asked. He was almost certain that the Sentry suit would have brought nothing but bad memories for Bob and yet he wanted to wear the suit anyway. To say John was confused would have been an understatement.
Bob gives him a bright smile, and it cheers John up far more than he would like to admit.
“I thought about wearing one, but then I thought if I was gonna be hanging around you that the Sentry suit would be a better option, y’know?”
Something in the air changes between them suddenly, and John swallows hard as he looks back at Bob. There’s a look in the man’s eyes he can’t quite place, and it makes his knees go weak and his stomach do a flip.
He knows.
There’s a stand off between the two men as they stare at each other, each of them silently daring the other to make the first move.
“If I do anything you don’t like, I want you to tell me to stop, okay?”, he asks John, and it takes a moment before the man can finally gather enough brain cells to nod back at him.
“Okay.”
In the end, it’s Sentry that makes the first move. He moves quicker than John had ever thought possible, rushing forward to invade his space and push him back against the wall, his knee immediately parting the blond’s legs before settling in between, grinding it against John’s clothed cock.
He let’s out a loud, choked off noise as a jolt of pleasure runs through him. He looks up at Bob’s whose features have an unusual hardness to them, and it takes John a moment to remember that Bob is putting it all on for him. He feels far too lucky.
“Bobby...fuck.” He keens under Bob, and he catches a sudden spark in the other man’s eyes as he grips John’s chin between his thumb and forefinger and tilts his chin up a little.
“You can call me Sentry”, he says, and the expression he wears is so serious, so cold, that John has to bite his lip as hard as he possibly can to stop the moan that threatens to leave him.
John’s embarrassment falls over him in waves and makes a deep blush colour his cheeks. Bob chuckles darkly as he lets go of John’s face and instead chooses to reach down to grind his palm into John’s cock. The pressure he uses is too light and the friction isn’t nearly enough, but John finds himself chasing it anyway. He thrusts his hips up into Sentry’s hand, once, twice, before Bob’s free hand finds his hips, holding them in place.
He hides his face in the crook of the other man’s neck and groans. He’s so fucking frustrated right now he could die and his cock is starting to leak so much that it’s darkening the front of his pants.
“Do you think the public knows that in his spare time their beloved hero the US Agent wants to be bent over and fucked until he can’t form a coherent thought?”, Bob—no Sentry, mocks him. John doesn’t want to answer that. Mainly because the answer is yes. And mainly because he doesn’t want to admit that Sentry is right.
When John doesn’t answer the hand not on his cock moves to tighten around his throat, squeezing gently, a warning. “You better answer me, John”, Sentry snarls at him, his face coming inches away from John’s own, and he struggles to hold Sentry’s gaze. He swallows audibly.
“N-no...Sentry...”, John squeaks, his voice far more pathetic than John would have liked and he’s surprised by the slight but genuine fear he feels with Bob’s hand around his neck. He could kill you, he thinks, but quickly pushes the thought aside. Bob wouldn’t do that. Christ, what was wrong with him?
He shakes his head hoping to get rid of the thought and hopes that Bob doesn’t notice how distracted he just became.
“And what exactly do you think they’d think of you, huh?”, Sentry spits at him like it’s a trick question, but John doesn’t want to leave it unanswered in fear of what might happen if he does. His blue eyes find Sentry’s gold ones again and he tries to look as unbothered as possible.
“I think they would think of me as a weak man. Shameful. A whore.” The words that come out of John’s mouth are surprisingly honest, and that same shame from before makes him ache, but this time it’s not a bad ache, no, it makes him want.
“Is that what you are then, a God’s whore?”, Sentry asks him, his tone not unkind but highly suggestive, and it has John’s cock twitching in interest. What the man was suggesting sounded too good to be true, although John knew it would never work, they both did. He had a job to do and couldn’t just quit to be at Sentry’s beck and call whenever he wanted to fuck him.
His mind tried to push away the scenarios where he was making it possible. Where he would no longer be the US Agent, only a compliant body for Sentry to use however he chose.
“Y-yes...”, John couldn’t help but let the word slip past his lips. He was already too far gone in all of this, and he was already close to begging for the chance to come, but his pride was somehow very much intact still, and Sentry was enjoying breaking him.
Sentry let out a soft hum as his hand moved from John’s cock to the waistband of his pants and pulled them down his thighs before taking them off completely. The ache in John’s cock was almost unbearable now. It was an angry red, leaking pre down the shaft, dripping slowly onto the floor.
Instinctively, John reached down to wrap his hand around his cock to bring himself some kind of relief, but Sentry was faster, catching his wrist in a bruising grip, a sneer coming to rest on his face. “Don’t even think about it, John.”
“Fuck...Bobby—Sentry, please...please let me...”
Sentry didn’t say a word to him, only shook his head in response and John felt like crying.
“Sentry...please, fuck—please fuck me...I can’t wait”, John is trying his hardest not to seem like an impatient brat, but he’s having a difficult time keeping himself under control. The smirk Sentry gives him is enough to shut John up and he watches as the man heads over to his bedside table and starts going through one of the drawers. He pulls out a half empty bottle of lube a moment later and throws it over. John catches it with little effort.
“Get yourself ready for me, baby”, is all Sentry says to him , and John nods and starts to move. He feels like he’s floating, although he’s almost certain that he’s probably dying instead. It feels like all the weight has been sucked from his body as his brain slowly fogs over.
It doesn’t take long before Sentry is satisfied with him enough to finally move closer again. John hears the sound of a zipper and he glances down. There was a zipper hidden along the seam of the suit. It was probably designed to allow Bob to be able to go to the bathroom in the suit, but John’s mind travels to the filthiest of places and he can’t help but grin.
“You plan this, Bobby?”, he asks, cockily, and immediately regrets it because he’s just realised that he’s not supposed to address Bob like that. He glances quickly between the floor and Sentry’s face, waiting for strong hands to find his throat again...but they don’t. Bob grins back at him instead.
“Kind of, yeah” is all he says before that invisible switch that Bob seems to have switches back and John’s left facing Sentry again.
There’s a lot of things John wants to ask about what Bob just said to him, but he knows there’ll be time for that later and right now all he wants to do is have Sentry fuck him until he can’t even remember his own name.
He lets out another string of curses as he pleads for Sentry to fuck him. It’s possibly the most humiliating thing he’s ever done, but he’ll do it for Bob. John knows he must look absolutely wrecked already because his skin feels too hot all over, his hair is sticking to his forehead and he’s panting heavily.
Something gives in him when Sentry finally takes his cock out for him to admire and John let’s out an embarrassingly high-pitched whine. The head of Sentry’s cock teases his hole for a moment, making him suck in a breath as he waits for the man to thrust into him. But it doesn’t come, not yet.
Hands find the underside of his thighs and suddenly John is being picked up like he weights absolutely nothing and his back is being pressed against the wall again. He wraps his legs around Bob’s waist and holds onto his shoulders for dear life.
When Sentry pushes inside it’s slow, he wants John to feel every inch of his thick cock fill him and John lets out a strangled gasp, screwing his eyes shut. His cock stretches him—John knew that his fingers would never have been enough anyway and he hisses as he takes inch after inch of Sentry’s cock until he’s bottoming out.
He sets a brutal pace that had John arching against him, pulling out almost completely before thrusting back inside again. John lets out a low mewl of a moan as he clings to Sentry, his eyes rolling back as the tip of the man’s cock hits his prostate dead on.
“Sentry!” John keened, trying his best to roll his hips in time with Bob’s thrusts, but he was finding it increasingly difficult to move with his hold on him.
John’s grip on the man’s shoulders was so tight that his knuckles were beginning to turn white. Sentry’s lips caressed the shell of John’s ear, whispering words of praise and encouragement as he chased his own pleasure, fucking into John over and over again until the only thing the blond could do was cry out for him.
Little “ah, ah, ahh” noises spilled from him—broken up every time Sentry thrust up into him again—echoing around the room. He could feel his orgasm approaching fast—the fact that he was about to come without Sentry touching his cock not being lost on him, and he pressed his face into the crook of the man’s neck.
Sentry’s thrusts were becoming erratic, a sure sign that he was getting close and John couldn’t help but get a little excited at the thought of being filled with Sentry’s cum.
“Fuuuuuck”, John groaned when Bob spilled inside him, his own orgasm hitting him soon after, turning the edges of his vision white. He pressed his forehead to Bob’s shoulder, trying his hardest to get his breathing under control because, fuck, that was one of the most intense orgasms John has ever had, and Bob didn’t even have to touch him.
When he’s finally alert again, the first thing he notices is the concern in Bob’s eyes as he walks over to lower him gently on the bed.
“John? You okay—was that okay?”
John nods quickly, not wanting to worry him. “I’m okay, Bobby. I’m okay.” He pauses for a moment, the full reality of the situation only truly sinking in now. “But what the hell was that, Bob? I—you knew...”, is what he finally settles on and John watches in disbelief as Bob’s lips start to curve upwards. Bob laughs.
“I’m sorry, I should have said something when we were on better terms again...but I had to take this opportunity, and I didn’t know when the others would be gone long enough to let me do this, so it was kinda impulsive”, Bob explained, and John let out a heavy sigh, amazed.
“Impulsive is one word for it I suppose”, he chuckled, pulling Bob closer to him and trapping him in his arms as he gave him a tight hug. “That was so fucking hot, Bobby.”
Bob’s face is suddenly covered with a dark blush that John thinks is absolutely adorable, and he suddenly realises that he has the Bob he knows back. He smirks at Bob.
“You get bursts of confidence like that often, Bobby? Cause I gotta admit I wasn’t expecting that from you”, he asks and Bob shakes his head.
“Not too often. Mostly I get too embarrassed to do anything with it, but I’ve wanted to try this for a while...and that day, when I fought you guys, I noticed how you reacted to me and I guess I just figured I had nothing to lose.”
John’s stunned to silence by Bob’s confession. He knew about what was going on in John’s head this entire time, all the filthy thoughts he’d tried to push away, Bob had probably guessed them all.
John kisses him them, deeply and passionately and he feels Bob melt against him. It doesn’t last very long, more meaningful than anything else, and when he pulls back Bob has a bashful smile on his face. John smiles back.
“Thanks, Bobby. I-I love you...”
Bob pecks him on the lips three times for good measure and rests his head on John’s shoulder.
“Love you too, John.”
