Chapter 3: Knotting in His Sweet Little Step-Sister

**Cathy's POV***

Panic shot through my chest as the doorknob jiggled again. The sound of my mother's voice was like a bucket of ice water over my feverish skin, yet the thick, swollen knot of my big step-brother was still locked deep inside my womb, anchoring us together on the broken bed.

"Logan? Cathy?" Mom called out, her voice closer now, laced with concern.

"Quick," Logan hissed, his amber eyes flashing with a sudden, sharp focus.

With a brutal, wet pop, he forced his swelling knot to slip out of my stretched channel, making me let out a muffled whimper. In one swift, powerful motion, he grabbed the thick duvet from the floor and threw it over both of our naked bodies, pulling me tightly against his side.

"Okay, I'm coming in." My mom warned. The bedroom door finally clicked and swung wide open.

Mom stepped into the room, her eyes instantly assessing the entire place. As the Luna of the pack, her presence was always commanding, but right now, her posture was stiff. She looked at the sunken mattress and the splintered wood.

She didn't appear entirely shocked to see Logan in my bed because when we were younger, he used to play with me and cuddle me to sleep all the time. But he hadn't slept in my bed since I turned sixteen, making the sight of him, nearly naked, and pressed against me in my pink duvet very awkward.

"What is going on in here?" Mom asked, her brows furrowing as she took a step closer. " And what was that loud crashing noise I heard from the hallway?"

"Cathy was feeling quite feverish," Logan lied smoothly, his deep voice steady as he tightened his arm around my shoulder, pulling my head into his sweaty chest. "Her first heat is fighting against the suppressants. She was shaking and crying, so I decided to cuddle her to keep her warm until she fell asleep. The bedframe was already faulty, it just broke when I climbed in."

I smiled and nodded in agreement. But, underneath the duvet, my heart was hammering against my ribs so hard I thought it would burst. The heat in my belly hadn't gone away—it was searing back to life, fueled by the thick, sticky semen dripping down my thighs. My hand roamed downward beneath the sheets, my fingers brushing against the hot and heavy velvet skin of Logan's cock. It was already rock-hard again, throbbing with a thick pulse. Driven by the shameless demands of my small wolf, I wrapped my small hand around his massive shaft—it didn't quite fit though—and began to slowly stroke him.

Logan’s chest heaved, and a low, uncontrollable groan rattled deep in his throat.

Mom’s eyes snapped directly to him, her gaze sharpening with suspicion. "Logan? Are you alright?"

Logan swallowed hard, his jaw clenching as my grip tightened around his thick cock, my thumb rubbing messily over the leaking tip. "Nothing," he gritted out, his voice so rough. "I'm just... incredibly tired from work. The alpha duties have been heavy today." He cleared his throat and tried to distract her. "Could you please tell one of the maids to prepare my bath? I need to wash off."

Mom didn't move at first, she just kept staring at us with hard, suffocating suspicion. Her eyes lingered on my flushed, burning skin, then, she looked at Logan and forced a motherly smile.

"Of course," Mom said, her voice strangely calm. She looked at me again and added, "I'll have the maids prepare some hot soup for you too, Cathy. To help with the... fever."

Without another word, she turned on and walked out of the room, pulling the door shut behind her.

The moment the lock clicked, Logan let out a feral growl. He didn't waste a second. He pinned my wrists above my head with one hand and gripped my neck with a tight, possessive hold in the other.

My breath hitch.

"You little brat," he whispered hoarsely, his eyes burning with pure lust. "Stroking Daddy’s cock right in front of your mother? You really are a filthy little whore, aren't you?"

He didn't wait for an answer. His mouth slammed into mine, his tongue invading my mouth in a rough, bruising kiss that tasted like copper and smoke. I kissed him back just as fiercely, my thighs parting on instinct, begging for his heavy cock to fill the empty ache inside me again.

"Logan..." I gasped against his lips, my voice trembling with fear. "Do you... do you think she knows?"

Logan let out a deep, mocking chuckle, his thumb tracing my sensitive gland. "She's the Luna, little one. Her scenting skills are almost as high as mine. If I can perceive the heavy, musky scent of the sex we just had dripping off these sheets, so can she. She knows exactly what I just did to her innocent little daughter."

Panic seized me, and I opened my mouth to complain, to cry about the danger of what we were doing, but Logan shut me up by smashing his lips against mine again.

"Don't worry about her," he growled against my mouth, his large hand sliding up to grab my breast, bruising the flesh. "All you need to worry about is how you're going to keep taking this big cock. Because I'm already completely obsessed with your tight little pussy, Cathy. I'm going to ruin you."

With one brutal, massive thrust, he slammed his huge cock back inside me, burying himself in my dripping wetness. I cried into his mouth as he leaned down and sucked my sensitive nipple into his mouth.

It was a sharp, blissful pain—a raw, blinding pleasure that tore through my sensitive insides. And as Logan began to pound into me again on the ruined mattress, my wolf purred in total submission, dreading the terrifying realization that I was never, ever going to be able to stop craving my big step-brother's touch.
