****** Alpha Rut ******
by wisia
Summary
     Three times Tony handled an Alpha in rut because he doesn’t always
     need rescue from heat.
Notes
     Okay, to confess, I dreamt last night about alpha beta omega
     dynamics—which is really strange because I normally don’t dream
     fandom tropes. Anyway, it was bizarre and it got me thinking I should
     do a reverse. Tony as an Omega always have someone “saving” him with
     their dick when he’s in heat. And I thought, let me do the opposite.
     What about an Alpha in rut who needs it as desperately as an Omega in
     heat does? Let’s write Tony and Rhodey because come on. So many
     things! Then, the more I thought about it, the more I thought—damn. I
     need to write Steve and Tony, and then Tiberius and Tony. And well, I
     decided to go for broke and write all three of them. ;____; It also
     came out more porny than I expected…
     Well, enjoy.
Tony inhaled sharply as he entered his apartment. The air was thick, almost
cloying with Ty’s scent. Everything was rich with the smell of sharp rain and
bitter metal. It made Tony a little dizzy, and he could feel himself wanting to
drop into subspace. Which wasn’t cool at all. He shouldn’t have to deal with
that after an entire day of boring lectures with stupid professors. Tony closed
the door with as loud of a bang as he could possibly make, so that Ty knew he
was back.
                “Ty?” Tony called out, annoyed. “I thought I told you not to
leave your damn scent everywhere. I hate it when you mark everything. What if
my parents visit?”
                Because Ty had a compulsive need to mark Tony as his, right
down to the furniture. It should have been funny to imagine how Ty must have
rubbed himself off everything in the apartment, but Tony only felt tired. And
he seriously wanted to kneel. Stupid Ty who of course wasn’t answering in spite
of plastering his scent everywhere.
                “Ty?” Tony called again. “Ty, did you hear me?”
Tony dropped his bags and books at the door, toeing off his shoes. He wondered
if maybe Ty just came and left his scent before leaving. It certainly wouldn’t
be the first time, and Tony resolved to order an entire box of odor
neutralizing products. He shouldn’t feel the need to roll over when entering
his own goddamn place. As Tony walked further in towards the living room, Ty’s
scent became stronger. It was suffocating, and Tony could barely blink before
Ty slammed into him.
They fell to the floor, the carpet a terrible cushion against the hard wood
panels. Tony felt as if he brained himself from where his head had knocked
against the wood.
“Hey! Watch it! You’re making me lose precious brain cells.”
“You smell so good,” Ty whispered, nuzzling his nose into Tony’s skin. His nose
was cold and uncomfortable. Tony shoved at him.
“Yeah, and you don’t.” Seriously. The pheromones were heavy in the air, and
Tony bit his lip in effort to keep from going under. He didn’t know why, but
Ty’s scent, more than anyone else, tended to trip Tony into going down quickly.
It was very hard to resist at times, and he was still learning how to handle
it. Tony bucked against Ty who was still nuzzling into him, but it didn’t budge
the other man at all. In fact—
“So good,” Ty said again. “So very good.”
He licked a stripe against Tony’s neck before biting down directly. Right over
Tony’s gland. It wasn’t even remotely hot. In fact, Tony yelped because it was
just that painful.
“Ty! That hurts.”
Ty ignored him, biting down harder in response, worrying his teeth into the
flesh. Tony winced. He was going to get a bruise for sure.
“Ty, Ty,” Tony said, hands struggling to hold Ty back. “I’m not in the mood.
Come on, get off.”
It was only then that Ty stopped abruptly. Tony’s eyes went wide as Ty flared
his nostrils. He could see now how black and blown wide Ty’s pupils were.
Different from his normal I want to fuck you.
“Ty?” Tony said softly, questioningly. He shuddered as Ty pushed his head back,
exposing his neck even further. Ty’s scent rose, the pheromones doing their job
of sinking Tony down to a place he didn’t want to go right now. Tony felt so
light headed.
“Tony,” and Ty’s voice came out thick and rough. “Are you my omega or not?”
“I am,” Tony said, more meekly than he wanted to sound. He could hear the
warning there because yes, Tony was his and he has to act like it.
“Then, let me have you. I can’t think like this.” Ty stroke his neck with a
thumb. “It’s so hard to think.”
“But Ty,” Tony protested. “I have work to do.”
That was the wrong thing to say because Ty pressed his fingers against the
column of Tony’s neck, cutting off some of his air. Tony wheezed.
“Ty,” he choked, praying he wasn’t going to die because he said no.
“Tony, Tony.” Ty breathed heavily, gaze hard and unwelcome as it travelled up
and down Tony’s body. “Don’t you know what you do to me? You make me so hard,
so desperate for you.”
And Tony could feel it. Just how hard Ty was against his thigh, how Ty rolled
his hips into Tony’s.
“I need you. Want you badly. Come on.”
Tony’s mind finally click into gear. He stared at Ty incredulously as the
pieces connected in his head.
“Wait. Ty, are you?” Tony licked his lips nervously. “Are you in rut?”
Ty only groaned in answer, rolling his hips into Tony again. He relaxed his
grip a little, allowing Tony to gulp as much air as he could.
“Come on,” Ty wheedled. He tugged at Tony’s shirt, rucking it upwards. “Aren’t
you mine?”
“I’ve—I’ve never,” Tony stammered, feeling stupid for not recognizing how Ty
needed him. What kind of boyfriend was he? Though, Tony had never seen an Alpha
in rut before. Ty rocked into him again, fingers playing with Tony’s nipples
because he finally got Tony’s shirt off. It sent Tony’s mind scattering.
Tony whined at how Ty pinched the nubs before fastening his mouth over one and
sucking hard.
“Ty, I don’t.” Tony swallowed hard as his brain worked sluggishly to think. He
wasn’t supposed to do this. “We haven’t really talked about this.”
“Please,” Ty whispered into his skin. “Please, baby. This is your job, isn’t
it?”
“Ah.” Tony struggled to make his mouth work. Ty’s hand smoothed its way down
Tony’s side and onto the curve of a hip.
“You don’t want to be bad, do you?” Ty asked, yanking Tony’s pants down. No,
Tony didn’t want to be bad at all.
“B-but,” Tony started and slipped into a moan. It was fine, right? Ty needed
him.
“That’s right,” Ty said. “You help me with my rut, and I’ll help you with your
heat later.”
His hand slipped lower, caressing every bit of tender flesh.
“Look. You’re so wet, so slick,” Ty said as he slipped two fingers into Tony’s
hole. It burned, and Tony jerked at the intrusion without preamble.
“Too fast, Ty.”
But Ty wasn’t listening. He nipped at Tony’s soft belly, fingers working
roughly at opening Tony up.
“So good. So good, Tony.”
Tony couldn’t really think, and it wasn’t till he felt an intense pain that
Tony realized Ty had breached him. Before he was quite ready to take him.
“Ty!” Tony gripped Ty’s shoulders hard. It was too much, too soon.
“You can take it. I know you can. You’ve taken more than this.”
Tony nodded, trying to adjust to the pain. It was okay. Ty was in rut, and he
supposed it was expected. That Ty would be less…might forget to prep him better
and, and be rougher in general.
“Yeah,” Tony murmured and reached for Ty’s mouth. “Make me sink.”
And as they kissed, Tony allowed Ty’s rut and everything send him spiraling
down till he was numb and wet with slick that might ease the way a bit.
                However, it wasn’t till Rhodey that Tony learned what a real
rut was because Ty was a conniving bastard. He did think it was strange that Ty
went into rut so often and more frequently than what he had read. Tony burned
with shame to wonder just how many of those bruises and growling were actually
from a rut and those Ty lied about.
                When Tony snuck into Rhodey’s dorm room, Tony could smell just
how overwhelming and overpowering Rhodey’s scent was. Jet fuel, high altitude
air, and honey scored the room, an odd mixture of sweet and gasoline. It was at
least a hundred times more than Ty had ever put out, but it didn’t immediately
sent Tony straight onto his knees and into subspace. This was something Tony
could deal with and could still think even as his biology wanted.
                “Tony?” Rhodey’s voice cracked. He was huddled in bed, beneath
a thin blanket, back against the wall. “What are you doing here?”
                “Checking up on you, honey bear,” Tony said glibly. He could
feel himself reacting, only one foot past the door. Tony wanted so bad to
please, but he kept it in check. He couldn’t go down yet. Not that Rhodey would
let him either.
                Rhodey groaned, though whether that was in want or genuine
annoyance Tony couldn’t tell. Maybe it was both.
 “Get out.” Rhodey threw a pillow at him. It was a testament to how far Rhodey
was gone because it didn’t even make it beyond the bed. Tony closed the door
behind him lightly. Deliberately.
                “Why? And let you have all the fun?” Tony said casually and
practically owned the small stretch of ground that took him from the door to
bed.
                “Tony, I’m not joking.” Rhodey growled, but it only sent a
thrill of excitement down Tony’s spine instead of scaring him off like it
should. “I’m going to go into rut soon, and—“
                “That’s why I’m here,” Tony said, crossing the last few
centimeters to the bed. Rhodey pressed himself to the wall some more. As if it
was going to stop Tony’s advancement.
                “No, Tony. No.”
                “You know you want me, sweetie pie.”
Rhodey stared at him. Tony watched as he opened and closed his mouth several
times before he could finally speak.
                “Tony, you’re seventeen.”
                “So?” Tony knelt on the edge of the bed, perfectly balanced.
Rhodey whimpered, just the slightest.
                “Tony.”
                “Really. You’re telling me you want to go through a rut alone?
When you don’t have to?”
                Tony let his jacket slipped off his shoulders in one easy
movement. He knew exactly how he looked, and Tony would be damned if he let
Rhodey suffer by himself. Not when Tony was right there, willing and available.
It was the least he could do for Rhodey. Tony owned him so much, more than he
could say.
                “Seventeen,” Rhodey repeated with a shake of his head. “You’re
too young.”
                Tony scoffed. “Please, I had sex before.”
                “What? Who?” Rhodey growled suddenly, and Tony felt himself
grow slick. Wet at how that alpha voice sounded to his ears.
                “Why? Jealous?” Tony asked and stripped off his shirt. He
smirked at Rhodey, cocking his hip seductively. Tony knew how his pants hung
low enough to expose that expanse of skin.
                “No!” Rhodey said loudly. “Are you crazy? You’re—you’re
underage, Tones!”
                “Didn’t stop me. Or them,” Tony said with a shrug, rolling his
shoulders in a way that only highlighted his features. “Come on and make me see
stars, sourpatch. Or are you really being sour?”
                “Tony,” Rhodey said so evenly and calmly that Tony had to
wonder at how he could control himself. Ty would have jumped him already by
now.
                “I’m not…it doesn’t matter if I’m in rut. I can handle it.”
                “But you don’t have to,” Tony said, confused. “I mean, doesn’t
every alpha want an omega when they’re in rut?”
                Rhodey looked entirely frustrated, and Tony took the chance to
edge forward. Scooted closer on his knees till only a mere inch separated them.
                “You’re telling me you don’t want me? I’m offering you to let
you plow into me till I can’t walk or think straight anymore.”
                Rhodey closed his eyes, breathing hard and heavily. His scent
peaked and then stifled as if Rhodey was trying hard to suppress what he
wanted.
                “Rhodey, Rhodey bear,” Tony said softly. “I’m not just saying
this.”
                “I know,” Rhodey sighed. “But I can’t. I don’t know where you
got the idea tha—I don’t need an omega when I’m like this. Besides, I could
hurt you.”
                “No, you won’t.” Tony was sure of that. Rhodey opened his eyes
and fixed a stern look at Tony.
                “I’m not joking,” he said, hands twitching before they came to
rest on Tony’s hips. Tony put his hands over Rhodey’s before Rhodey could pull
them back, away from him.
                “If you don’t want to, I won’t push. But I definitely want to
and I don’t mind.” Tony frowned. “Unless…you don’t want me?”
                He tried to ignore how his heart twinge a little at that. That
maybe he was wrong, and Tony really shouldn’t be here.
                “I—I want,” Rhodey admitted, hands clenching tight on Tony’s
hips. The action made Tony swayed forward, relieved.
                “But I shouldn’t.”
                “It’s my choice,” Tony said. “It’s not just because of the
hormones talking. Give me one good reason why shouldn’t I help you out when
you’re in rut. Come on. It’s simple.”
                “I, okay. Okay,” Rhodey breathed. “I just don’t want to do
anything you don’t want. Rut is no excuse to sleep with someone.”
                “You really aren’t doing what I want,” Tony shot back. “You
smell good. You’re going into rut. And you still haven’t really touched me much
less kissed me.”
                Rhodey smiled as Tony’s babble washed over him. “I guess I’ll
have to fix that, huh. If you’re sure.”
                And he carefully slipped a hand behind Tony’s head, tangling
his fingers into the thick brown messy curls there.
                “I’m sure,” Tony said quietly when Rhodey paused. “Really.”
So, Rhodey gently nudged Tony’s head into place and kissed him softly, sweetly.
Tony opened his mouth on immediate contact. It was nothing like Ty’s. So heated
and so good.
                “God,” Rhodey said, breaking the kiss.
                “Good, right?” Tony panted and shifted till he was practically
straddling Rhodey. He rocked into Rhodey, making them both groan.
                “Don’t,” Rhodey said haltingly. “Do that. I—“
                “It’s not so bad,” Tony said. “You don’t seem that crazy.”
                Rhodey rocked back against him, harder and rougher. “Not quite
there yet. But in half hour or so I’m probably not even going to be able to
talk.”
                “Really?”
                “Oh yeah,” Rhodey breathed against him, pressing his nose into
Tony’s neck. “I get non-verbal when I’m in rut. Mindless. Grunting and
growling, I guess.”
                “So like a zombie?” Tony teased. Rhodey nipped his neck
playfully.
                “I’m going into rut. Not being—not being undead.”
                “Right,” Tony said, letting himself sink. “Now, come on and wow
me.”
                Rhodey did, and even as he finally fell into rut he was still
very careful as Tony knew he would be. Tony didn’t mind Rhodey’s growls and
rough manhandling one bit. Hell, he didn’t even get any bruises.
                And years later, Tony found himself handling one Steven Grant
Rogers.
                “D-do you think you could?” Steve said hesitantly. He rubbed
the back of his neck where it was just as pink as the blush splashed across his
cheeks. Tony didn’t really notice because they were down in the lab, and he was
making good headway into adjusting and tweaking Steve’s uniform to utter
perfection.
                “Yeah?” Tony said, absently as he flicked the current design
away for the previous one to study.
                “Well, I—,” Steve cleared his throat. “Tony, would you mind
joining me when I have my rut?”
                “Hm, yeah—wait, what?” Tony looked up from what he was doing,
jaw slacked. Steve blushed harder.
                “You heard me,” Steve said.
                “No, I didn’t.”
                This made Steve laugh. “I—would you share my rut with me?”
                “I don’t know what to say,” Tony said. “Wait, no, I do. Really?
You, the fine specimen that you are, are asking me to take you?”
                “I wouldn’t say you’re taking me,” Steve said meaningfully.
                “In a matter of speaking,” Tony waved and eyed Steve
lecherously. Steve rolled his eyes before his expression turned solemn.
                “Well, I understand if you don’t. It’s not exactly safe, and I
haven’t really gone into rut since—”
                “Wait? Who say I won’t?” Tony asked. He tugged at Steve till he
was standing between Tony’s legs. Tony fluttered his eyelashes. “Anything for
Captain America.”
                “Tony,” Steve said because he was so very serious. “I might
hurt you. I’m stronger than most alphas.”
                “Eh,” Tony said flippantly. “Can’t be worse than any of the
other ruts I’ve been in.”
                At that, Steve raised an eyebrow. Tony looked back at him,
refusing to feel ashamed.
                “Don’t look so surprised.”
                “I’m…,” Steve pressed his lips together. “I’m not. I’m aware
that you have a rich experience.”
                “Oh, you’re cute,” Tony said and patted Steve on the cheek.
“It’s okay. I’m a slut. You can say it.”
                “Tony!” Steve went scarlet. “You can’t say that.”
                “It’s true,” Tony said, drawing a leg up and hooking Steve
directly into him. “And I’m honored to share your rut. How can I refuse when
you ask so nicely?”
                “Uh,” Steve said, scrambling for words.
                “So, right now?” Tony asked. “Or is it going to be in a few
days? Wait, who cares? Let’s start right now. We can practice and see how you
fit into me. I want your knot. I bet it’s so nice and big and fat.”
                “That’s—,“ Steve fumbled as Tony leaned up suddenly, tugging at
Steve’s shirt collar, because Steve was just that tall even if Tony was sitting
on a high stool.
                “Yes?” Tony asked cheerfully.
                “Yes,” Steve said and kissed him soundly.
                It was going to be a rut that Tony could more than handle, and
probably more than once.
