Chapter 5: Knotting In His Sweet Little Step-Sister

**Cathy's POV***

My heart hammered against my ribs, a thrilling spark of fear and arousal shooting through my veins. I didn't hesitate to obey his command.

I slid off the couch and dropped onto my knees on the rug, right between his powerful, parted thighs. The position felt so right—like I was born to kneel between Logan's thighs—making my wolf purr with submission. I pulled the blanket over both of us, draping it over my back and his lap so we were completely hidden from view if Mom happened to open her eyes.

Underneath the cover of the blanket, Logan didn't waste a single second. He untied the strings of his sleeping pants, shoving them and his boxers down to his thighs. His cock sprang free, completely rock-hard and pulsing with heat. In the shadow beneath the blanket, it looked monstrous—the size of my forearm, the thick purple veins standing out aggressively against the rigid shaft. The fat head was already leaking a heavy amount of sticky precum.

"Look at it," Logan grunted, grabbing the back of my neck and forcing my face closer to his crotch. "Daddy’s cock is quite big for you, isn't it, Cathy? Look how it's throbbing just from looking at your pretty face."

"It's so huge, Daddy..." I breathed, my mouth watering as his heavy, musky scent hit my nose like nicotine.

"Lick it," he commanded in his alpha voice, his grip tightening around my ponytail. "Taste how salty your big brother is."

I leaned in, dragging my tongue from the heavy base all the way up to the swollen tip. He let out a low, rough grunt, his hips twitching into my mouth. The taste was rich, male, and thick with arousal. I gave the glistening head another wet lick, wrapping my lips around the top, but he was so wide I could barely fit half of the head inside my mouth.

"Good girl," he growled, his fisted hand aggressively tugging at my hair. "Suck it just like that. Make those wet, sloppy sounds for me, little slut."

I tried to accommodate him, slurping eagerly, my saliva making a complete mess of his shaft. The thrill of giving him head right in front of our sleeping mother made my skin hum and my heart race.

"Fuck, you're doing so good, keep going baby," he voice sounded strained, his breath catching as his thick cock pulsated inside my mouth.

I wanted to please him so bad, making loud, wet noises as my tongue rolled along the tight, hot skin. Logan's breathing turned into deep, beastly grunts as his control completely snapped. He grabbed the top of my hair, his hands tight as he began to rhythmically thrust his huge cock down my throat, making me gag and swallow around his thick girth.

"Oh baby, your throat feels so fucking hot," he whispered hoarsely, his movements becoming frantic as his heavy balls slapped under my chin. He moved faster and faster, driving me absolutely insane with his dirty words until he let out a deep, deafening guttural roar that he had to choke back.

He gave a final, deep shove into my mouth, and I gagged as his hot, gooey semen poured down my throat. It kept coming, wave after wave of thick, tangy liquid filling my mouth to the brim. I swallowed the rich, salty warmth of his release, completely dazed and wasted from the taste of him.

"Fucking hell," Logan groaned loudly, his entire body trembling tightly as he slowly pulled his softening length from my lips with a loud pop. He looked at me with dark, hooded eyes as he placed a soft kiss at the top my head. "Good girl," he panted, his hands rubbing my hair. "Now, your turn."

He didn't give me a moment to blink. He swiftly maneuvered my trembling, feverish body, arranging me flat on my back against the couch. He reached down and yanked my soaked shorts straight down to my knees, leaving my bare, dripping pussy exposed to the cool air.

Logan went down on his knees and dived between my parted, quivering thighs. He began to eat me out hungrily, his hot tongue lapping over my swollen clit.

"Logan..." I let out a choked whimper, my hands flying to cover my mouth as he French kissed my entire dripping pussy. I was aching and dazed from the heat, my slick running down my inner thighs in a sticky stream.

Logan was relentless, slurping loudly and making an absolute mess of my wetness. The erotic sounds of his mouth working against my sensitive flesh filled the quiet living room. Soon, I felt my orgasm swell in my abdomen, slowly tilting me over the edge from the intense friction of his tongue.

"Logan! Oh goddess, I'm gonna cum!" I gasped, my hips bucking helplessly against his face.

A vicious climax ripped through my body. My pussy spasmed hard as a heavy gush of slick burst from me. Logan eagerly sucked down the sweetness of my release, licking my cunt clean until my body finally stopped quaking.

Just as the intense throbbing of my orgasm began to ease, Mom stirred on the couch. Her eyes fluttered open, still heavy with sleep, and she rubbed her face.

Logan moved with terrifyingly fast Alpha reflexes. In one smooth motion, he slipped out from between my legs, shoved his cock back into his trousers, and pulled me back up into a proper sitting position beside him, wrapping the blanket around both of our shoulders just as Mom looked over.

"Oh dear," she muttered, her voice raspy and disoriented. "What time is it?"

Logan and I giggled softly under our breath, our hearts pounding in our chests as we sat perfectly composed, hiding the sticky, sinful mess we had just made right under her nose.
