Chapter 7: Knotting In His Sweet Little Step-Sister

**Logan's POV**

Sitting in the waiting room of the pack hospital, I kept my eyes entirely on the door of the examination room. A couple of nurses passed by, giggling and giving me long, lingering looks, but they didn't exist to me. My focus was entirely consumed by the sweet girl currently being evaluated behind those closed doors. The lingering scent of our steamy fuck in the car created a relentless sweet hum beneath my tight skin, driving my inner wolf to a possessive edge.

The door finally clicked open, and Cathy stepped out, looking small and slightly overwhelmed by whatever had happened in there. I stood up instantly, my large frame easily taking up the distance between us in two strides. I pulled her into my arms, wrapping her in a tight, protective embrace and pressing a firm kiss into her soft hair. She melted against my chest, her hands clutching the back of my shirt.

"All done, little wolf," I murmured against her crown. "Go sit in the waiting corner by the front desk. I'll take care of the paperwork."

Before she could walk away, Dr. Evans stepped out of the office, his posture stiff, his beta scent heavy with anxiety. He looked at me, then at Cathy, before clearing his throat. "Alpha Logan. A word in my office, please," he said nervously. Then he added, "Alone."

I patted Cathy's shoulder, signaling her to go ahead, and I followed the doctor into his room. I slammed the door shut behind me, taking in Evans' office. He didn't sit down behind his desk; he paced for a moment, his mouth pressed into a thin, worried line. As the Alpha, my presence alone was enough to make the pack doctor sweat, but the volatile tension in his scent told me this was about something else entirely.

"What is it, Evans?" I demanded, crossing my arms over my chest.

"Alpha..." Evans swallowed hard, adjusting his glasses. He carefully kept his distance, choosing his next words with extreme caution. "There is a very serious problem regarding your stepsister's test results. Cathy's first heat has definitely arrived—which we expected given her feverish symptoms—but... it appears another Alpha has already scented her. And taken advantage of her."

I kept my expression entirely neutral, my jaw clenching slightly to play the part of the concerned guardian. "Go on."

"The laboratory analysis found undeniable traces of an Alpha's..." a hard swallow, "...semen in her system," Evans said, his voice a horrified whisper. "And given the hormone levels in her bloodwork... Alpha, she is almost certainly pregnant. A pup is already forming inside her."

A dark, savage thrill surged straight through my veins. A wide, satisfied smile played on my lips before I could hide it. My wolf howled in absolute victory.

My pup.

The thought of Cathy's petite body growing heavy and round with my babies, bound to me forever by blood and a fated lock, aroused me to the core. I couldn't wait to formally claim her, to lock her away in my quarters where no other male could ever look at her. Damn the pack laws, damn the step-sibling labels, and damn anyone who dared try to stand between us. She belonged to me.

"Alpha? Alpha Logan?"

Evans's urgent voice snapped me out of my thoughts. I blinked, looking back at the scrawny doctor, whose face had gone completely pale at the sight of my smirk.

"We need to act immediately," Evans insisted, misinterpreting my dark expression as anger toward the unknown perpetrator. "Cathy is still so young, just starting her gap year with her music classes. Whoever did this violated pack protocol by crossing territory lines to claim an unbonded omega. We need to deploy the pack guards, track down this rogue Alpha, and have him arrested immediately."

I straightened up to my full height, towering over the desk, my expression as stern as possible.

"Don't worry about it, Doctor," I said, my voice dripping with absolute authority. "Leave it to me. I'll handle the... Alpha myself."

Doctor Evans could do nothing more than nod in obedience.

I returned to the pack estate much earlier than usual. I had dropped Cathy off at her afternoon music studio, but the image of her sitting on my lap in the SUV, completely submissive and taking my huge cock, had completely ruined my concentration at the office. I had spent the afternoon locked in my study, masturbating twice just to ease the agonizing horniness that her scent had left in my blood. It hadn't worked. My cock was still heavy and aching inside my trousers.

I was heading toward my master bathroom to take a cold shower and change into fresh clothes before picking her up from class when a heavy knock came on my door.

"Logan? It's Alice. Open up."

My stepmother's voice was tight, stripped of its usual warmth. I frowned, throwing a towel over my shoulder, and pulled the door open.

Alice stepped into the room, her face pale, her eyes rimmed with sadness. She looked like she'd been crying; maybe the heavy burden of her grief from losing my father last year still caused her pain. But then, the flash of anger I caught passing through her eyes denoted one thing only.

Accusation.

"What's the problem, Mom?" I asked, my tone guarded as I closed the door behind her.

She stood in the center of my room, staring at the floor for a long, agitating moment before her eyes snapped up to meet mine.

"I know, Logan. I know exactly what is going on in this house between you and Cathy."

My expression hardened, my wolf stirring in warning, but Alice didn't take the hint to back down.

"I smelled it on the linens yesterday, and I smelled it on her when she came down to dinner," Alice said, her voice trembling with a mix of anger and heartbreak. "Cathy has started her heat, Logan. You are the Alpha of this pack. You were supposed to protect her from the chaos of her cycle, but instead, you took advantage of her vulnerability. In her own bedroom."

"I did protect her," I growled, taking a predatory step forward. "I protected her by putting my scent all over her. I marked her away from every other filthy Alpha in this territory before they could even get a whiff of her fertility."

"She is your stepsister!" Alice yelled, her shoulders trembling as she took a step toward me, her eyes flashing with maternal fury. "She is too young, Logan! Far too young to be engaging in this kind of primitive, fated mating—and with an Alpha of your caliber, no less! You could ruin her!"

"You don't need to worry about Cathy's well-being," I gritted out, my fangs scraping against my lower lip as my wolf pushed to the surface. "I am going to take very good care of her. Better than anyone else ever could."

"Logan, this is madness—"

"She was meant to be mine, Alice," I interrupted, the finality in my tone cutting her off. "The Moon Goddess ordained it the moment her heat answered my bond. She belongs in my bed, and she is the sole keeper of my heart." I breathed hard, my chest expanding. Then without a second thought, I declared, "I love Cathy."

"No!" Alice cried, as if the apocalypse were about to happen.

"Listen to me carefully," I growled, leaning down to stare right into my stepmother's eyes, my own eyes glowing with a feral dominance that demanded absolute submission from even the pack's Luna. "If anyone in this pack or any outsider tries to take Cathy away from me... they will suffer the consequences. I will tear this territory apart before I let her go. Do you understand that?"

Against her will, Alice lowered her head and nodded. With one last look of disgust and disappointment, she stormed out of my room, slamming my door so hard that one of the hinges broke.

My heart sank as my dominant wolf retreated, leaving me to bear the hurt of a man who had let his primal urges take control and did the irreversible.

I was in love with my stepsister Cathy, and no one was going to stop me from having her completely. Not even the rational part of me.
