Bob’s laughter cuts through the tense atmosphere and John’s head snaps around to glare at him. 

“What’s so funny?” He demands, a growling bite to his words that should serve as a warning to Bob, but he’s never been smart enough to heed warnings. 

“It’s just, I used to fuck guys like you in prison.” 

John, who had been gearing up to storm over and shoot that weirdo in the head freezes at those words. It’s not the words necessarily, it’s how casually it’s said. It’s a threat is what it is, and that stupid Bob guy looks far too confident and calm for John to not take it seriously. 

Yelena and Ava look at John with raised brows, waiting to see what he’ll say to that. It’s not that he’s a coward, it’s just that he knows there are certain battles worth waging and this one isn’t. 

He clears his throat, “Whatever, you fucking freak. Let’s just figure out how to get out of here.” 

And the whole scenario should just go to the back of his mind and be something he just forgets about, but he doesn’t. Not even after getting his assed kicked by the Sentry and then having to save the world from the Void. Not even after months of New Avengers work where he’s finally getting some good PR and decent jobs that don’t require him shadily murdering random scientists that Valentina decides are a liability. 

Those words just continue to echo through his head, ‘I used to fuck guys like you in prison’. 

John has gotten known Bob, has gotten to learn to his timid awkward presence in the tower. Despite all the signs pointing to the contrary, John does not for even a second doubt that that statement Bob made all those months ago is true. Seeing his angrier, more unhinged side as the Sentry really cemented it. And in prison with probably no access to his bipolar meds, John fully believes that Bob made bitches of every single inmate in his cell block. 

Which leads him to his most embarrassing secret–he wants Bob to fuck him. 

Not in a nice way either, he wants the Sentry. He wants cruel, mean Bob to rearrange his insides while spitting on him and telling him how pathetic he is. He wants to be fucked like those guys Bob used to fuck in prison. 

John ends up using his shiny New Avengers paycheck money to try and find a solution to his “Bob” problem. Thank every god out there for discrete packaging. He thinks he’d literally kill himself if any of the others found out about his purchase. 

When the box finally arrives, he tries to be as casual as possible as he collects it from the pile of mail sitting on the kitchen counter. Outwardly, he looks a little bored, but inside his heart is hammering away. Bob looks up from the dishes he’s washing with a frown. Before he can say anything, John is retreating to his room with his package in tow. 

John immediately rips into the box as soon as he’s alone. The website had advertised it as being made with material to feel like real skin, and when he gets the  hard plastic casing around it open, he does have to admit it feels very skin-like. The dildo itself, though, is large and weighty with a suction cup base and veins all along the shaft. 

His mouth waters at the sight of it, already imagining it’s Bob’s cock. He thinks about him grabbing John by the hair and forcing him to his knees. And he could, with his inhuman strength, and John would be helpless. 

He starts licking up and down the dildo, picturing Bob looming above him, imposing and arrogant as he was when he was Sentry. He starts working it into his mouth, roughly forcing it as far back as possible. He chokes but he doesn’t let up because he wouldn’t want Bob to let up. He’d want him to fuck his face–to use him like he used those guys in prison. 

He barely gets started in his fantasy when he’s interrupted by a knocking on his door. He yanks the dildo out of his mouth and scrambles to hide the evidence of it. He shoves it under his duvet and shakes himself out, trying to look normal. He does have to tuck his boner into the waistband of his jeans to hide that bit of evidence.

He answers the door with a scowl, “What?”

Bob is standing on the other side of the door, his brow furrowed in concern. 

“Hey…”

John’s eyebrows cock up in annoyance, “Yes?”

Bob tugs at his sleeves nervously and god above, John hates that this absolute wet noodle of a man is his ultimate sex fantasy. 

“I just wanted to see if you were okay-“ 

John cuts him off, “I’m fine, Jesus Christ is this why you’re bothering me, Bobby?”

Bob’s teeth grind hard in his mouth at that, and his eyes flash golden for a second and oh–

John can’t stop himself from poking the metaphorical sleeping bear. 

“What, you think I need you of all people to check on me? What a joke.” 

Bob’s face starts to twitch into a snarl but he blinks rapidly and visibly tries to shake off the anger, “Knock it off.” 

“Or what, Bobby? You gonna fuck me like those guys you used to fuck in prison?”

That comes out of him without his permission, a sort of Freudian slip except it was more of a straight confession.

Bob looks stunned at the comment before his eyes flash golden again, “You really don’t know what you’re asking for, Walker. Stop now while you’re ahead.” 

John laughs meanly and crosses his arms, “Make me.”  Famous last words and all that as John, faster than his brain is capable of processing, finds himself flung onto his bed with Bob– no, Sentry, pinning him down and with his hand wrapped around John’s neck. John instinctively goes to fight back but Sentry is, as established, way faster and stronger than him and incapacitates him embarrassingly quick. 

“This is your final warning–“

As Sentry shifts to loom over him, he feels something hard under the duvet of the bed. Reaching down he yanks it back and lets out a chuckle at what he sees. 

“Is this seriously what has you all worked up today?” Sentry wags the dildo in Johns face, “You really are just so pathetic.” 

The moan that escapes him is entirely involuntary and he knows his face is cherry red from it. Sentry just looks stunned, like his brain has blue screened or something. The mutant’s head tilts to the side as he assesses John far more closely. 

“You’re just a horny little dog, aren’t you, Walker? ‘Goading me, baiting me, for what? Do you think I’ll fuck you?” 

John looks away in shame but Sentry’s hand squeezes his face roughly and yanks it to face him, “I asked you a question.” 

“Yes,” Walker eventually mutters, the shame of months of sexual repression flooding him all at once. 

Sentry releases his face and leans back, looking down at him with those glowing, golden eyes. 

“Well, Walker, you’re going to have to earn it. Show me what a good little dog you are.” 

He climbs up off the bed and stands in the middle of his bedroom. John doesn’t need to be told twice as he scrambles onto the floor, crawling up to Sentry on his knees and kneeling at his feet. 

Sentry hums and with a quick flick of his hand, opens his pants. John surges forward, yanking them down and messily sucking down his semi hard cock in one go. The dildo has nothing on Sentry, the silicon could never compare to the heat and salt and size of him. He moans pathetically as he rushes to take him as far as he’ll go and Sentry just runs his fingers through John’s hair. 

“That’s a good boy,” his praise tinged with a mocking tone, “Suck my cock.” 

The fingers in his hair tighten to a painful degree and suddenly Sentry is fucking his face hard. Forcing him down further and further with each pull until John’s nose is buried in the trimmed hair at the base. He holds him there for a long time, long enough that John starts to panic a bit when he runs low on oxygen, his hands scrambling at Sentry’s thighs. It’s only when John feels like his lungs are going to explode that he’s yanked off his cock, sputtering and coughing. 

“You should count yourself lucky that you’ve never actually been to prison, you would’ve been someone’s girlfriend before you’d have even made it to your cell.” 

Sentry pushes his shoulders down until his head is on the floor and his ass is in the air. There’s no finesse or teasing as his pants are literally ripped off of him, easily tossed away by the man pinning him, “I’m going to fuck you now, and you’re going to say ‘thank you’.” 

Sentry lobs a wad of spit directly onto John’s asshole, and works two fingers into him. It hurts but god does it also feel good. He practically melts into the carpet, his hips already pushing back to meet Sentry’s thrusting fingers. Before he’s ready, a third finger is added and Sentry remarks, “God, you really are just a whore.” 

John moans and nods, “I-I’m a whore.” 

The man above him laughs meanly at that and runs his cock head up and down his crack, teasing at his fluttering hole. He doesn’t enter though, just pressing and then pulling away and pressing and pulling away. 

“P-please!” He begs, pushing his hips back in hopes that Sentry will relent. He doesn’t though, just keeps teasing him. 

“I don’t think you’ve earned it, yet,” Sentry tells him, “I don’t think you really want it enough.” 

“I’ll do anything, just fuck me pleaseeeeeee!” 

The end of his sentence turns into a squeal as Sentry shoves himself to hilt inside of him, starting a brutal pace of fucking him without any time for adjustment. And John loves it, this is exactly what he’s been wanting, exactly what he’s been needing. And Bob, ever the benevolent guy that he is, is finally scratching that itch that John’s needed scratched all this time. 

The pace at which he’s being fucked is brutal, no ifs ands or buts about it. He wonders vaguely if he’s even going to be able to sit normally when this is all done. He reaches down, trying to grab his cock but a loud smack and the burning pain on his ass cheek stops him. 

“I don’t let stupid dogs cum,” Sentry snarls at him, putting almost his entire weight onto him as he fucks him, “You said you wanted to be fucked by me, that should be enough.” 

John nods dumbly, only now realizing he’s crying. Sentry just laughs and rests his palm on the side of his head, using that to support part of his weight as he continues to rail him. 

“Fuck I’m so close, say, Walker, do you think with all these genetic enhancements they made to me that I could get you pregnant?” 

John’s brain whites out at the image and he’s coming untouched, his cum making a mess of his carpet and thighs and Sentry somehow manages to fuck him even harder. 

“I’m gonna put a baby in you, Walker, and then you’ll be my little wife.” 

John can feel it when he cums, the fluid is hot and there’s so much of it, it’s like Sentry has been storing it up for him. 

There’s an embarrassing audible pop when he pulls out and John tries to block his view of his ruined asshole with is hand but Sentry just grabs it and twists it into a painful position. 

“Hey Walker, your hole is completely wrecked. It’s time for you to say ‘thank you’.” 

When John doesn’t comply he twists his arm even more, the dangerous creaking noise coming from his wrist says he has seconds before it snaps. 

“Okay fine! Thank you!” 

Sentry releases him and stands up, “We should do this again some time.”
