****** I'll Protect You ******
by HopefulAtrocity
Summary
     He promised he would protect her. -Sequel is in the works-
Aiden stared at Kali like she had lost her mind. Who did she think she was,
messing with what was his? He’d rip her fucking head off before he let her
touch Lydia. Lydia was his, damnit. Not that stupid Stilinksi kid’s. Not even
Scott’s. 
HIS.  
Even though she would deny it, he knew that she bore his mark and that no wolf
could encroach onto his territory.  
A deep growl vibrated out of his chest, and he took a step toward Kali in
warning.
She was slightly shocked at his disobedience but then she smiled with an eye
roll.
“Oh really? Did someone take their little assignment too seriously?” she
circled him slowly, running her claws over his shoulder. The sharp tips of
them, just barely slicing the soft leather of his jacket.
“The problem is not with me.” He growled loudly, his eyes flashing red.
“Maybe the problem is with where your loyalties lie. Really, Aiden? A human? A
weak one at that..” she looked at Lydia with another eye roll.
That was the last straw. His wolf burst through its inner cage, and clawed out
at the other Alpha. HOW DARE SHE? Lydia was anything but weak. She was annoying
as hell, completely disobedient, and possibly insane, but she was NOT weak.
Lydia was beautiful, smart, and his. He wasn’t going to stand for Kali talking
bad about his woman.
He’d promised her he would protect her and that was exactly what he planned on
doing.
Gosh she was so beautiful. With her flaming hair fanned out on his pillow like
a friggin’ halo. Aiden looked into Lydia’s eyes, hooded from pleasure. In the
beginning, she had been very dominant, always wanting to be on top, but after
he pinned her to Finstock’s desk and took her rougher than ever before, she
became very submissive. And it was fucking hot.
She looked gorgeous underneath him, squirming as he pounded into her. Digging
her nails into his back, he nuzzled the side of her jaw, forcing her to bare
her throat to him. His teeth grazed the delicate point of her pulse before
biting down. Coppery blood filled his mouth as Lydia screamed in pleasure. She
really was a screamer.  His thrusts sped up to the point of being inhuman. The
wolf inside him was pacing, waiting for him to relinquish control over to the
beast. It wanted a turn with his mate.
He hated that he couldn’t feel the tight heat of her against his cock, covered
in a condom. It would be heaven to feel her clenching around him. But she
insisted, and how could he resist her.
Lydia grabbed at his short hair and pulled him up to kiss him deeply. “Please,
faster, Aiden.”
God this woman would be the end of him. He sped up, his hips blurring with
speed. Her orgasm closed around them both and Aiden was overtaken by emotion.
She was coming undone beneath him, his mark on her neck. It was a sight. One
that was forever seared into his mind.
“Mine!” he growled and pinned her arms above her head. Lips crashed together.
His thrusts were losing pace and frenzied. He needed to be closer to her.
His climax washed over him before he had the chance to pull out of her
clenching heat. The knot at the base of his cock swelled quickly and locked him
inside of her. It was different. Normally he was able to stay in control and
stop the knotting from happening. But he felt closer to her than ever before.
Her glazed eyes looked up at him as he stretched her inner walls. She was in
such a daze that she couldn’t find it in her to care that he’d passed the
boundaries she’d warned him not to break down.
His cum poured out in long spurts, so much that the condom popped inside her.
Warmth rushed through her as his seed filled her womb.
“I’m sorry,” he whispered to her before nuzzling the mark he made on her neck.
“If anything happens, I swear to god, I’ll protect you.”
His hand drifted between them and ran over her stomach, where his future child
would probably grow.
Aiden raised his clawed hand above his head, aiming for Kali’s throat. That’s
when he heard it.
The slight fluttering of a heartbeat.
His wolf instinctively raised its head, following the sound to the strawberry-
blonde next to his brother.  She was clutching close to Ethan’s side, not used
to the anger she saw in his eyes. Aiden dropped Kali, half-unconscious, to the
floor and stalked over to Lydia. Ethan placed a hand on his chest, warning him.
But he shrugged his brother off, and dropped to his knees in front of her.  The
fluttering increased and he sorted through the heartbeats in the room. Ethan’s
was strong, and very familiar. Kali’s was slow, almost nonexistent. Lydia’s was
fast, but strong.
He pressed his ear to her stomach. The fluttering continued but was louder as
he placed his ear over the source. Pregnant. She was pregnant. 
Her fingers ran through his short hair, pulling his gaze up to her.
“I told you I would protect you,” he whispered and pressed a kiss over her
belly. “Both of you.”
