DAY 9 - BITCHING/STUDDING
"I'm an Omega." Steve declared to you, and you felt your world drop instantly.
You had been wishing that he would turn into an Alpha after you presented, but it seemed as if the world was mocking you right now. Omegas dating each other was rarely talked about. Most of those couples had to seclude themselves from the world in countrysides so they wouldn't run into an Alpha that would make their instincts go wild.
Maybe you could do that with Steve… But you couldn't leave the teens behind. The pups that were going to present at some time in the future, and you had to take care of them. You needed to.
You felt your eyes tearing up as you looked down at your lap, sitting on his bed. He had told you he was sick all week, and you were hoping he was hiding the fact that he got hit with a rut… But it was a heat. A presentation heat.
He could sense your disappointment, and it made him want to whine, but he held back, not wanting to even do that himself. He walked over to sit next to you. You two just sat there, looking at nothing. You couldn't have children together, and that was one of the things you two wished for the most.
You two loved each other, but…
"It won't… work out…" You breathed out, and Steve's breathing hitched. Was he going to lose you? Just like that? Even though you were right, you and he had gone through way too much to just part. It couldn't end like this.
His eyes drifted away, looking at the picture on his night table with you. He then saw the little stone you got him that changed colors depending on the weather and heat… Changing?
He stood up, abruptly, and you jumped at the motion, making you look up at him, wide-eyed and with a tear-stained face.
"What's—?"
"I need to call the clinic, and I will need your help." You blinked at that, completely confused, tilting your head.
"What for? Are you feeling—"
"I'm gonna ask for a studding treatment." Your eyes widened, standing up right next to him, shaking your head.
"Are you insane!? That has a fifty-fifty chance of working, and even then, your whole body changes, and it's painful, Steve!" He grabbed your biceps tightly, his eyes teared up as he shook you slightly.
"I will try anything to stay with you! I want children with you, and a future, and you are my best friend, and if I lose you, I would not be able to bear it! I will not…" You stared at him, feeling tears running down your cheeks, and you were still uncertain about it, but Steve was not backing down. "I love you… Let me do this…"
—
"Alpha… Do you think we are close?" You asked Steve, already having gotten the Alpha/Omega roleplay under control. At first, it was weird, embarrassing even, and Steve's Omega fought and hissed at the name, but it slowly started accepting it.
The sex was… weird in the beginning. His cocklette wasn't big enough for you to feel much, and he had to fight the urge to whine for a knot himself. You kept calling him 'Alpha' while he basically humped you, pretending to be thrusting into you with his cock. You sucked him off to make him cum, but you were forbidden from touching his slit where his ballsack should be.
If you do anything Omega-like to Steve, the process would have been for nothing. You had to be submissive and compliant, while Steve had to be protective, dominant, and strong. His instincts fought and fought, but in a week, he started to love taking care of you.
This also applied to the pups and your friends. You had to be like a motherly figure, while he had to look threatening to anyone who disturbed his pack. Billy taught him how a growl should feel, and that by no means should Steve do a chirp or a purr. Your boyfriend was scared it might escape him, but Billy was very supportive in his decision, as well as his Omega, Eddie.
Both of them tried their best to guide the two of you in Alpha/Omega dynamics, and you have seemed to get the hang of it all.
A week went by, and Steve had been experiencing pains, sometimes big, sometimes small. But he underwent the biggest change of all, and one that there was no going back from.
He had no slit. A ballsack started falling down, and his cocklette was now a little shorter than average. He could actually fuck into you and shoot his slick through his cock. It should be a matter of time before it turns into his seed, and he could fill you up with his pups. That thought thrilled him. Seeing you round with his children, as many as you were willing to give him.
His arms came to wrap around your middle from behind, his mouth pressing against your shoulder.
"Mmm… I think so… I don't have any more Omegan needs." You purred at his words and nodded happily, a smile on your face as you closed your eyes. You felt a little hotter than usual, and you were certain that your heat was not due right now. It should be in a month, so it was probably just a fever.
"I think I'm sick, baby…" He lifted his head from your shoulder, frowning with worry.
"You feel ill?" You nodded, and he hummed, kissing the tip of your nose. "Then go lie down, Omega. I'll go make some tea, okay?"
You nodded, smiling at him as you walked towards your room. You hadn't built a nest yet because Steve might have wanted to claim it as his own. You tore the one you had apart after he presented, and that was the worst thing you've ever done. It felt as if something was ripping inside of you.
You felt a cold sweat invade you as you took a sharp intake of breath. Pain seared through your belly, your lungs, and your fingers itched, and burned. Your bones felt like they were cracking, and you could feel the room burning.
And your body moved on its own. You were breathing heavily as slick started slipping down, covering your underwear, and even the sundress felt like it was suffocating you. You ripped it off instantly, throwing it to the ground. You ran your hands over your face, and you realized just how sweaty you were. It didn't make sense.
You were experiencing heat symptoms. It was impossible. It shouldn't happen, not this early. You couldn't have a heat right now, because it might trigger Steve's. Fuck. You weren't conscious of your movements as you rushed to grab Steve's dirty clothes from the bin, throwing them on the bed.
"Shit…" You whimpered in pain, clenching your eyes as you got yourself together. Breathing heavily, you started fixing the clothes into a nest, neatly, as best as you could in this state. You didn't have a warning or time to prepare.
You should warn Steve, but all you could do was take off your underwear and get in the middle of the bed, completely naked. You were going to mess everything up. Your Alpha will be so mad at you for going into heat and fucking up his own process. You would not be able to be with Steve the way you wanted to.
And then, an intense smell came through your nose that made your body shiver, and your slick to gush out. You were curled into yourself, and you managed to look towards the door, and the answer was just standing in the doorway.
Steve was in rut.
He was in a presentation rut.
He was huffing air, staring at you inside your nest, his sweatpants now tight from the hard on that was happening in them. His nose was flaring, his muscles were tightening, and he could feel his mouth salivating at the mere sight of you. At the scent of your slick, of your arousal.
His steps were heavy, his shirt discarded, and you whined at that, not wanting his used clothes to go to waste. You kneeled up, tears running down your cheeks as you held out your hand. The air became thick as he pulled his sweatpants off, as well as his boxers. Your eyes went towards his shaft, large and thick, with a red tip and precum coming out of it. It was bigger than ever before.
You whined again, and he offered his boxers to you, and you rapidly took them, pressing them against your nose. The scent of your Alpha calming down your pain, relaxing your belly. You opened your eyes to see him trembling, looking down at your nest.
"Please… Please, let me in…" He begged, and you put his boxers at the top of the nest where your head would rest, before you extended your arms at him.
"Alpha, come to me, please— Help, it hurts—" You cried, and he immediately stepped in, his arms coming to wrap around your body, pulling you flush against him.
You had never been sweeter. You had never tasted better than you did now, and all he could think about was breeding you. The only thing he could think about was to mate you for life. You are his and his only. He was made to be with you, no matter the circumstances.
You took him into your mouth as he ate you out. The slick was falling onto his face, but he didn't care. You were on top of him, cunt on his mouth, and chest against his stomach.
You smiled with satisfaction the moment you presented to him, chest on the mattress, knees planted on it, your ass shaking with need towards him. He didn't hesitate, and seconds later, he was railing into you like a madman. You were crying out, feeling full for the first time in so long. He felt like he was being engulfed in flames and sweat. His head and body hurt, but because of need rather than pain.
"Feels good, baby, god, it feels so fucking good—" You moaned, and all you heard was a rumbling, a growl, because Steve was not very articulate at the moment. His eyes were black, pupils so dilated that it almost didn't look human.
You cried out to him as you bounced on the mattress, coming around him twice, not knowing how much time had passed since he had you in that position. His hands were gripping your ass, pulling you towards him at each thrust, and your knees were killing you, but you didn't care.
"Omega— Knot— Fuck!" You heard him scream, and your eyes widened when you felt his base enlarge inside of you as he kept himself still. His hands gripped at your skin, trying to center himself as he felt knives stabbing his stomach. It was painful now. He felt his skin stretch out, and it felt as if it were ripping apart.
"Alpha!" You clenched around his knot, and he finally let out a loud moan of satisfaction as he came inside of you. He trembled on top of you at each spurt, and you were milking him dry. The pain was gone, and it was as if the world was different somehow. Everything smelled different. His eyesight was sharper, and his mind was more determined. He felt… strong.
The room was a mess, the mattress was drenched in slick, sweat, drool, tears, even cum that had spilled from the edges of his knot and your pussy. You were both panting heavily, and you could feel your back killing you now. The position made you completely sore, and you felt two strong hands guiding your hips sideways so you two could lie down.
His chest was pressed against your back, trying to catch his breath as he panted against your back. He kissed your flesh, and you felt your mating gland burning with need. You turned your head over your shoulder, a tired smile on your lips.
"We did it…" You said, and he smiled, kissing your left shoulder, nipping at your skin, teasing you. You whined, clenching around his knot, making him growl. This time, it really was an Alpha growl. "Don't tease me…"
"I'll mate you properly in my next rut…" He promised, and you purred in happiness at that, your hand moving behind you, twisting a bit to properly look at him, your hand in the back of his head.
"Can't wait for that, Alpha…"
