Chapter 4: Knotting In His Sweet Little Step-Sister

**Cathy's POV**

I couldn't stop staring at Logan. He sat across from me at the mahogany dining table, the cool evening feeling like a dream. He suddenly looked even more attractive and more rugged than I had ever thought him before.

I had always loved him, ever since I was a little girl. Our parents had gotten married when I was only eight and he was eighteen. His father had died just last year, leaving Logan to shoulder the entire pack. Now, I was nineteen and he was twenty-nine. For a decade, he had completely doted on me. He bought me whatever I wanted, showered me with beautiful gifts, and never said no to his little step-sister. How could I not have fallen in love with him?

My mind drifted to a past event, the sweet warmth between my thighs flaring as I remembered the day that had changed the innocent love I had for Logan. I had been sixteen when I caught him in the small lounge downstairs. I hadn't clearly seen his cock back then, but I could hear the sloppy, wet sounds, his deep, low grunts, and the sight of his hand moving furiously fast inside his sleeping pants. That was the first time I had ever rubbed my own little pussy, hiding in the shadows and coming right to the view of my big step-brother masturbating.

Now, I finally had him. My wolf was completely satisfied, even though my pussy was swollen, sore, and clenching for more, thick slick already dampening my fresh panties. I subconsciously licked my lips, wondering how his massive cock would taste, if I could fit the whole thing in my mouth and—

My mom suddenly cleared her throat, snapping me out of my thoughts and forcing me to look away from my big brother.

Logan was eating his food hungrily. Alphas usually had massive appetites because they used a tremendous amount of strength. Logan needed his to govern the pack and keep the rogues in line. I, on the other hand, was a petite omega who ate very little, barely picking at my salad.

"Cathy," Mom called, her eyes fixed on me from the head of the table. "I'm taking you to the pack doctor tomorrow. Your heat fever could get worse and you could miss days of music lessons."

I didn't want to go to the hospital with mom. She always made the doctor give me too many suppressants and she scolded me like a child in front of him. As if hearing my thoughts, Logan quickly suggested:

"I'll take Cathy to the doctor myself tomorrow," he said smoothly, cutting a piece of steak, his large hands dwarfing the cutlery. "I have to visit the clinic to check on the pack guards anyway. I'll make sure she gets looked at."

Mom watched the two of us, her piercing green eyes darting between my flushed face and Logan's calm expression. After a long, dreadful pause, she simply shrugged and went back to eating her food.

Relief spread through me. I caught Logan’s eye across the table and silently mouthed, "Thank you, daddy."

A sinful smirk stretched Logan's lips as he looked into my eyes, his gaze filled with lust, and he mouthed back, "You're welcome, baby."

A surge of hot forbidden desire shot straight through my core.

After dinner, the three of us retired to the living room. It was a tradition; Mom always watched the evening news before heading upstairs to bed.

As usual, I sat as close to Logan as possible on the sofa, wrapped in the soft pink blanket he had bought me years ago. But tonight, being so close to him felt incredibly intense. The heavy scent of his woodsy alpha pheromones was making my head spin, and beneath the cover of the blanket, his large hand was already sliding over my hip, his fingers kneading my flesh.

Within twenty minutes, the drone of the news anchor did its trick. Mom’s head began to bob, her eyes closing as she slowly dozed off on the couch across from us.

The moment her breathing went deep and even, Logan took his opportunity.

He slid his hand down the waistband of my sleeping shorts, his thick fingers dipping into my panties. I gasped into his rigid shoulder as his fingers plunged directly into my dripping, swollen pussy. At the same time, he leaned over, tugging my shirt down and burrowing his face into the blanket to suck on my plump breast, circling his tongue around my aching nipple.

"Mmm..." I tried to moan quietly, my body arching into his touch, terrified of waking Mom.

"Quiet, little one," Logan whispered hoarsely against my skin, his fingers pumping hard and fast inside my soaking wet cunt, drawing out more slick. "You better not make a sound. I'll spank you until you can't walk for a week if your mom wakes up and catches us."

I mewled and nodded, his beautiful, beastly eyes burning into my hooded ones. I was so fucking horny. I wanted him to take me upstairs and fuck me hard, but Logan looked like he didn't have that much patience.

Suddenly, he grabbed my neck and pulled our faces close. Then he whispered in a dark, rough voice that vibrated straight through my swollen, throbbing core:

"Get on your knees, baby. Daddy wants you to suck his cock."
