The room echoed with the sounds of bodies colliding, Clarke’s muffled moans, and Lexa’s grunts of exertion.
Clarke bit into a pillow. Tears of pleasure slid down her cheeks while her body trembled from the effort. Her knees ached from the constant pressure against the bed, and her elbows had given out several minutes ago. Now, the only support she had in front of her was her cheek pressed into the sheets. It didn’t help that every thrust from the alpha made her body bounce.
Lexa had her firmly by the waist, using leverage to pull Clarke against her. Her short nails were already leaving red marks on the Skaikru woman's pale skin. Who would have thought that skin, which had looked so pristine and delicate that morning, would now be covered in bruises from the brunette’s strong grip and possessive bites, some of which had even begun to bleed.
“Harder,” Clarke mumbled almost instinctively, pulling away from the pillow she had been biting, a strand of saliva connecting her face to it. There was no reasoning left in her eyes; they were clouded by pleasure.
Lexa was completely satisfied. That omega would give her several pups...

That morning, a meeting had been held between Skaikru and the leader of the Grounder Coalition.
Lexa sat upon her fur-covered throne, considering whether accepting the Sky People's offer of peace was truly a good idea. After all, they were the ones who had burned three hundred of her warriors alive. She could not simply let that go unpunished, and accepting the alliance outright would mean taking no action in response to those deaths.
She needed something that would prevent her from appearing weak before her people, something that ensured they gained something in return. Beyond the “new technology” the Skaikru had brought with them, she needed something human.
Right in the middle of her thoughts, Indra entered, parting the hides that served as the entrance to her tent.
“Heda, the Skaikru delegation is waiting outside. Shall I let them in?”
Lexa did not have much time to think of a solution. She would decide during the meeting itself, depending on how it went.
“Yes,” she replied shortly.
The alpha did not expect a strong, sweet scent to call to her the moment the tent opened again.
An omega.
Quickly, she identified which of the Skaikru it belonged to. There was an older woman who was clearly an alpha, an older beta male, a young dark-haired beta who looked obviously angry, and finally a blonde girl...
It was her.
Lexa studied the omega’s body. She had good features, round and full breasts, perfect for nursing pups...
Pups?
Was she really thinking that?
She was surprised by the thought herself.
“Commander, we have come here to negotiate a truce,” the older beta began. “I am Marcus Kane, the current leader of Arkadia.”
Lexa pushed aside her previous thoughts and focused on what he was saying.
That beta was the leader of those who had attacked her people.
“You are the one who burned three hundred of my warriors alive,” Lexa accused, driving her knife into the armrest of her throne.
Her sharp gaze remained fixed on the beta.
“You are the one who sent them to kill us.”
A female voice spoke.
The omega.
Lexa realized that she must have been responsible.
“So it was you,” she confirmed.
“And you were the one who sent them,” the blonde replied.
An idea crossed Heda’s mind.
“It does not matter what happened before. What matters is that we are here now seeking peace between our peoples, especially when we have the Mountain Men as enemies—”
“What is your name?” the brunette interrupted.
The omega frowned, clearly annoyed by the interruption.
“Clarke Griffin.”
“Klark kom Skaikru, it is my duty to inform you that no alliance can be formed between our peoples while a blood debt of three hundred deaths remains unpaid.”
Lexa spoke with complete seriousness.
She felt satisfaction when she saw the eyes of the three Skaikru widen in shock. Fear was obvious on their faces.
Everyone except the omega.
She simply looked irritated.
“We owe you nothing. They would have killed us if we hadn’t acted first.”
Lexa had to admit that besides being beautiful, the girl was rather rude for speaking to her that way—and foolish, considering that if Lexa wished, she could have them all killed right then and there.
“That is not how it works. Skaikru must make amends in another way. I have a proposal for you, Clarke.”
Clarke raised an eyebrow.
“Since you were the one responsible for those warriors’ deaths, you must pay for them. A union between us would transform the debt into a pact. The clans would see that Skaikru is offering something of value in exchange for the blood that was spilled. Become my omega, and your debt will be paid.”
Clarke froze.
She had not expected anything like that.
“No, that’s impossible!” the younger beta shouted. “Clarke can’t stay with that savage!”
The woman who was probably Clarke’s mother immediately began protesting as well.
Lexa was growing tired of it.
She already had a plan, and she intended to see it through.
A low growl escaped her, and silence immediately settled over the tent.
The display of dominance was unmistakable.
“There is only one path to peace. The omega becomes my mate. Refuse, and there will be no peace. My army will retaliate against your people.”
Skaikru might possess better technology and weapons, but the Coalition army was vast. They could overwhelm them without much difficulty.
“I’ll do it,” the girl said without thinking.
More protests immediately filled the tent.
“Indra, remove them,” Lexa ordered in Trigedasleng.
Indra entered with two other guards, and together they dragged the others outside, ignoring the shouts and threats directed at them.
Clarke was left alone with the alpha.
Lexa rose from her throne and walked toward where the omega stood.
She noticed the tension in the girl’s body.
She looked as though she wanted to run, yet her expression showed something else:
Defiance.
Once she was close enough, Lexa took the omega by the waist and pulled her closer.
Feeling how perfectly she fit against her.
A scent of arousal began filling the entire tent.
It was not only coming from Lexa.
Most of it came from the blonde.
“You want me,” Lexa stated.
“Go float yourself” Clarke tried to protest, but quickly fell silent.
Her body refused to help her deny the alpha.
Her lower body ached. She was wet. Her thighs already felt slightly sticky.
Her body was ready to receive the Commander.
She could feel the Grounder’s body pressed against her clothed stomach.
It was firm and heavy enough that she could feel its weight against her.
Her body tightened around nothing as her mind filled with unwanted images of that same presence inside her.
Clarke was horrified by those thoughts.
Perhaps her heat was close, and that was what was affecting her.
“Commander, let me tell you that it is incredibly presumptuous of you to believe I could possibly feel attracted to you.”
Clarke used every ounce of calm she possessed to say the words without stuttering.
“Oh, really?”
A mocking smile appeared on the alpha’s face.
Lexa’s eyes shone with desire.
The omega’s scent was practically begging her to take her right then and there.
Meanwhile, Clarke thought about the mess she had gotten herself into.
She should have thought more carefully before agreeing.
But it was for her people.
And with the Grounders on their side, defeating the Mountain Men would be far easier.
Noticing how distracted the girl seemed, Lexa shifted slightly closer.
That omega drove her insane.
And she had not even properly scented her yet.
“Call me Lexa,” she said before leaning closer to scent the glands at the girl's neck.
She could detect the smell of arousal coming from them.
But also fear.
“I’m not a monster, Clarke. If you want nothing to do with me, you can leave.”
It cost her more than she cared to admit, but she stepped back and gave the blonde some space.
Clarke considered the offer.
Then she shook her head.
She knew that if she left, there would be no truce.
Besides, it would be a lie to say she was not at least somewhat interested in a girl her own age.
“No,” she said.
“I accept.”
---
And that was how they ended up like this, mating.
Lexa moved her hips with force and speed, wanting every part of Clarke to feel her member, and she was succeeding. The omega's tight cunt, recently deflowered by her, was practically choking her cock with how tightly it clung to it. Her shaft was nearly as thick as a fist, and Clarke's cunt seemed perfectly made to take it.
“You squeeze me so well,” she growled with effort, spanking the girl's pale ass. She was rewarded with more wetness spilling from Clarke's cunt, making the thrusts easier thanks to her natural lubrication.
“Lex... harder,” Clarke began moving her hips back, trying to meet Lexa's thrusts. That same night she had lost her virginity, and the alpha would probably get her pregnant, but those thoughts had no place in her mind right now. The only thing she could think about was how badly she wanted the grounder's seed inside her.
Lexa did as she was asked and doubled her efforts, twenty-four centimeters sliding in and out of the delicate body beneath her. She could feel her knot forming at the base of her cock. Her heavy balls constantly slapped against Clarke's ass, leaving her cheeks red from the repeated impacts.
By now, the entire grounder camp probably knew that the omega belonged to their Heda. The Skaikru's moans were impossible to miss, and the alpha wanted nothing less than for them to grow quieter.
“Beg for my seed,” she growled into the girl's ear, sending a shiver through her entire body. Releasing one hand from Clarke's marked hips, she snatched away the pillow and tossed it into the far corner of the tent. She wanted everyone to hear her claim herself as hers.
“Please, please, please, Alpha, I want your seed, give me your pups!” the omega cried desperately, moving her hips without restraint in an attempt to take more of her. The brunette's knot tried to push inside with every thrust but still couldn't fit because everything was so tight.
“If you want my cum that badly, then do your part,” Lexa said, biting her shoulder in an attempt to stimulate her even further. But she knew exactly what would finally allow her knot to slip inside.
While Clarke was busy lowering one of her hands to rub her clit, trying to produce more lubrication or at least relax herself further, Lexa wrapped a hand around the girl's neck and pulled her back against her, arching her body and giving herself a better angle. Her cock reached deeper than before.
Not deep enough, she thought.
“Please, Alpha, give me your—” the blonde couldn't even finish the sentence before a sharp pain shot through her body, and then everything went white. Her vision blanked out completely.
The alpha had taken advantage of Clarke's distraction to bite down hard enough to draw blood. She never released her grip on her neck. She was delivering her mating bite. She was marking Clarke as hers. The entire world would know that the omega had been claimed.
When the bite was complete, Lexa felt something loosen. She pulled her hips back and then thrust forward with all her strength, breaking through the resistance and forcing her swollen knot inside. Streams of cum flooded Clarke's defenseless cunt, painting it white. A sharp cry escaped the omega as she reached her orgasm as well.
Lexa was fully sheathed inside her. She had never felt so good in her life. It was a moment of complete peace.
Both of them collapsed forward, the grounder's weight pressing down onto the girl. Lexa swelled with pride when she looked down and saw her cum overflowing from her omega's abused cunt. Not even her knot could contain that much seed.
She began rocking her hips forward again, trying to empty everything she had into her. The existence of their future pups was practically guaranteed.
Clarke whimpered weakly beneath her. Lexa wrapped her arms around her while continuing her slow movements. With one hand she took hold of her chin and forced her to look up at her. Blue and green met once more that night. Both of them knew those sudden feelings were mutual.
The alpha leaned forward and gave her a hurried kiss, pouring every emotion she felt into it.
“Mine,” she thought as she kissed her.
