Tony’s nostrils flare as he looks down at his boyfriend. Peter looks back up with the most alluring, doe eyes. The boy whines, rutting his hips up against Tony’s hand underneath the blankets. Ever since he started his second puberty on T, he’s been even hornier than before.

“Please, please Tony, can we?”

“Are you sure, Pete?” He already knows the answer, Peter doesn’t ask for things he doesn’t want, but Tony wants to be absolutely certain that Peter is willing to give it a shot. It doesn’t matter that they’ve talked about this before, it’s been a few weeks since they had, and Peter’s body is a sensitive topic to start with. He’s grown into the young man he’s always been on the inside. Especially after his top surgery, Tony could see how alive Peter was. He still doesn’t remember how they got to the topic that night, but suddenly they’d been talking about Peter’s bottom growth, and while Peter had wondered about maybe getting bottom surgery in the past, he told Tony that he was now super content with his small, tiny cock…

…And how he fantasized about being humiliated about it.

“Yes, I’m sure daddy,” Peter pleads, and for good measure he quickly hooks his fingers into his boxers and wriggles out of them, leaving himself entirely exposed to the whims of his daddy. “I’ll safeword out if it’s too much, please, please don’t worry about it,” Tony growls pathetically and gently brings his fingers down again, dragging them across Peter’s slick hole to slick up his digits and using it as lube for Peter’s little cock.

“Look at that,” Tony starts slowly as he gently spreads the wetness across the hard bud. “Poor baby boy, you’re still so small, aren’t you? Nowhere near the size of daddy’s cock.” Peter gasps and nods silently, encouraging Tony to go on. Tony licks his lips and does what his boyfriend wants.

“My little boy, at the brim of puberty, and here you are letting your daddy touch you. You’re such a filthy little thing, you’re too young to be thinking thoughts like these.”

“I’m sorry, ‘m so sorry daddy, I just- I just can’t help it, I- Oh that feels so good. ”

“Yeah? Do you like it when I jerk you off like that? I bet you’re gonna come so fast. Do you wanna touch daddy’s cock too, baby? Feel how big I am compared to you?” Peter nods, his eyes glazy and needy, and his hand darts out to slip into Tony’s sweats and good fucking lord, the way Peter’s face contorts has Tony shiver. His cock tingles where Peter’s soft grip hits his skin and he bucks up, groaning. 

“That’s perfect, keep going, you’re gonna make me feel so good kiddo, hgnh!” 

Peter mewls softly and drops his head onto Tony’s sweaty chest, both of their bodies falling into the rhythm of soaring pleasure. Tony loves being Peter’s daddy, loves pretending to be his actual father-figure too, and seeing Peter’s reaction to it, he enjoys it just as much.

“I’msoclose, ” Peter chokes out, his chest falling heavy with each and every breath. His free hand clutches at the sheets while his other starts jerking Tony off faster. “ Tony- Daddy- I- ”

“Yes Peter, that’s it. I want to see you come all over yourself like a filthy boy.”

Peter cries out and when his back arches off the bed, Tony feels the way the little cock twitches between his slick fingers and he gasps, his eyes falling shut when Peter’s hand never fails to keep pleasuring him too. He focuses on the way his boyfriend shudders against him, his body being ripped apart by his orgasm, and then how his entire body sinks into him, only shaky gasps falling from his lips.

“Show me how it’s done, Daddy,” Peter croaks. “Show me how a real, grown man comes.” Tony hates the flaring blush staining his cheeks but he can’t think about it for too long, because the words reverberate in his mind and Peter’s hand is deliciously good and before he realizes what’s happening, his abdomen catches on fire, and his cock erupts in a series of white spurts that land on his abs. He growls, throwing his head back as Peter pumps him through it until the very last drop is squeezed out. 

They’re both quiet for a bit after that, quickly wiping their hands on the sheets and tangling their limbs together to come down from their high. Tony trails his fingers down the curve of Peter’s spine, smiling, and nuzzling his face against the crook of his neck. Peter sighs happily and giggles.

“That was fucking everything ,” he says, still very amazed. “Did you think so too?”

“Yeah,” Tony admits truthfully and tries to ignore the shame he feels in the back of his mind. Before Peter, he’s never been with someone he could indulge himself with. Despite having been together for over four years, he still feels these things whenever they try something new. But he likes it. He likes exploring, and he loves allowing Peter to do the same thing too. “You’re so hot like that. Was it what you expected from it?”

Peter nods, and to Tony’s surprise, there’s a blush on his cheeks too.

“Yeah. Knew I’d like it but didn’t expect to like it this much. I- I think I’d like to take it even further, ehhhh,” he stammers and presses his lips together until his cheeks blow up slightly. Then he huffs. “Next time, maybe you could tell me you’re gonna make a real man out of me?”

Tony frowns slightly.

“You sure? Doesn’t that- Isn’t that-”

“Transphobic? No. Not in this context, God- It’d make me feel like I’m inexperienced, rather than… unmanly. Does that make sense? I want you to be my daddywho teaches me things. ” Peter’s voice picks up in clarity when he keeps talking, and Tony relaxes his shoulders, hoisting Peter’s body even closer to cuddle him more tightly. 

“Well, in that case, son, I’ll teach you. This was only the beginning.”

The mischievous twinkle in Peter’s eyes says it all.

Trans!Peter & Genderfluid!Loki pt 2

• Loki gets turned human for the sake of this post so he can’t shapeshift anymore and he’s AFAB so that REALLY sucks
• Also he’s staying in stark tower cuz he can
• After only a few days Loki’s chest is dangerously scarred from mutilating himself there and trying to “fix it”
• Peter tries to lend Loki a binder and Loki pretends it fits but it’s way too small
• But he uses it anyway and it bruises him terribly and hurts like hell and makes it so hard to breathe and warps his ribs until one breaks and he still doesn’t tell anyone about it
• But then Tony turns on Dad Mode. “Peter told me he lent you a binder and not to be creepy or anything but I don’t think one of his would fit you. Are you being safe?”
• “Yes. Leave me alone.”
• Then Tony intentionally bumps him in the side and Loki can’t help a groan of pain. Tony makes Loki take off his shirt and he can see how fucking terrible it is even before the binder comes off. He helps Loki take the binder off while Loki cries in embarrassment pain and because he can see his chest now.
• Tony is like. Well shit.
• Loki’s cries would be sobs but he can’t breathe well enough to sob
• Loki refuses to be taken to the hospital so Tony does his damn best but there are some things that can’t be fixed
• Peter blames himself of course
• Then Loki wakes up as a girl and she feels better of course but she looks down at her chest in a non dysphoric way and she’s like wow I really did destroy this whole thing didn’t I
• And she’s kind of sad
• Thor doesn’t know about any of what happened so next time he sees Loki he slaps him on the back not especially hard but Thor hard and Loki gasps in pain and immediately whatever colour might’ve been in his pale ass face floods out of it and his eyes roll up into his head and he passes out from the pain.
• Thor is freaking terrified he thinks he broke his brother.
• Tony has to explain and Thor is close to tears when they get Loki awake again

Trans!Peter & Genderfluid!Loki

• Even if they’re technically enemies Thor still respects Loki so so much so of course uses appropriate pronouns whenever they change and he knows about it
• One time he’s talking with all the avengers about Loki and he uses “she” cuz Loki is a girl right now so he explains to everyone
• After that instead of being just an insane villain they understand Loki just a little bit better cuz that must be hard
• After whatever conflict that is is over Peter comes onto the scene
• He meets Thor and is of course hella excited and just totally adorable like he is
• And Thor starts talking about his sister, Loki
• Peter is a little confused so Thor explains that Loki was born female but found that she identified as male most of the time but still female some of the time so she’s genderfluid and right now Thor has a sister not a brother
• And Peter is internally like omgomgomgomgomgomgomg someone who is similar to me
• He explains that he’s trans to Thor and that makes Thor happy cuz the young spider opened up to him
• Thor admits that he still has contact with Loki even though they’re trying to kill each other just a little bit and Peter is excited he wants to meet this trans AFAB genderfluid asgardian villain
• Thor trust’s his sister enough and is 110% sure that Peter would tug her heartstrings in just the right way that she wouldn’t kill or manipulate him so he lets Loki know that she has a fan
• Loki obviously thinks it’s a trick until Thor is really insistent and pleading and she knows him and his voice and eventually gives in and then bip bop boop next thing you know Thor is ferrying Peter to meet Loki (who is male again)
• Thor stays very nearby but doesn’t eavesdrop just is near enough that if something happens he can slap a hammer on Loki’s head and carry Peter to safety
• Peter also has his suit on hand but isn’t wearing it
• “Hi it’s nice to meet you Mr. Loki sir!”
• And they talk for quite a while actually first about gender which is the whole reason that Peter wanted to see Loki in the first place but then about other stuff like parents and lonliness and Loki is surprised at how much of himself he sees in this bouncy little spider toddler
• They get along pretty well and even though Loki had at first been planning to manipulate Peter and turn him he actually truly doesn’t want to anymore because he doesn’t want Peter to be led down the path he took and especially not by Loki himself
• He gets pretty heckin soft for Peter after a few meet ups and their conversations go from completely deep about terrible dysphoria their worst mistakes regrets and childhood trauma,,, to really chill stuff like music taste (Peter introduces Loki to some things) and other interests (magic and science)
• One day “Hello Mr— oh! Hi Miss Loki!” And Loki grins so purely because the only other person who’s respected her like that is Thor
• And she can shapeshift so it’s really obvious what gender she is at any given time
• Basically Peter becomes Loki’s life after a while like screw taking over the world let me take care of this kid instead
• And honestly Thor is shook because Loki seems legitimately happy and Peter doesn’t seem brainwashed or anything
• But he decides to actually come be with the two while they’re talking one day and he’s surprised to learn a some things about his sister like she knows a lot about the plants on Midgard
• But it’s not nearly the kind of conversation Thor imagined them having
• He puts his hammer down
• “Oh, oh, Mr. Thor can I try to lift it!?”
• AND HE DOES IT JUST FLOOP AND UP IT GOES
• He swings it around for a little while while Thor and Loki are actually frozen in astonishment
• “Miss Loki, catch!”
• AND SHE DOES!,?!?!?!!?
• PETER BASICALLY CLEANSED LOKI EVEN THOUGH HE WENT LOOKING FOR HER FOR SOMEONE TO RELATE TO LOKI GOT HER FIRST REAL ACTUAL FRIEND AND KIND OF A SON
• Thor feels super outdone at this point tbh but Peter and Loki just wanna play catch with it
• Thor doesn’t let them he takes Peter home (stark tower just cuz) immediately but Loki follows them
• She appeals to Tony like please I’m fine now I just wanna protect this sweet summer child you have found and put in a spider suit
• The hammer thing is actually what convinces Tony she’s not a complete menace so she’s allowed to stay
• He’s a little shook that she’s a girl tho
