Chapter 6 CAUGHT JERKING OFF ON MY STEPSISTER’S PANT(1)

The shower spray was hitting the tiles in a steady rhythm, a sound I had come to recognize instantly.

It meant she was in there right now, completely naked, with hot water slicking down over her curves while soap glided sensually across skin I had only ever imagined touching.

My hot little stepsister, Ruby. She had just peeled off her clothes, and somewhere in her room, still warm from her body, were her panties — a tiny piece of fabric soaked with her scent, her heat, and her intimate essence.

My cock was already painfully hard, a deep, persistent ache that had been tormenting me all day because of her relentless teasing. My wolf was deep in rut today, burning through my blood and making every instinct scream with raw, primal need.

This morning she had worn those tiny shorts that barely covered her ass whenever she bent over to grab juice from the fridge. Her loose t-shirt had dipped low when she stretched, revealing the soft curve of her breasts and the tempting hint of a pink nipple.

She had caught me staring, of course. Instead of scolding me, she gave me a knowing smirk, a little shake of her head, and then deliberately turned away, letting me watch the seductive sway of her hips and the tight bounce of her ass in that thin fabric.

For months it had been like this — constant teasing bends, stretches that pulled her shirt tight across her perfect breasts, and soft giggles whenever she noticed my eyes locked on her. It was unbearable. It was exquisite, agonizing torture.

The moment the shower started, I knew I couldn’t resist my ritual any longer. Dad and Lauren were gone for hours, leaving the house silent except for that steady watery pulse.

My heart hammered against my ribs as I crept out of my room, my shorts tented obscenely from my throbbing erection. Ruby’s door was open, just as she always left it.

The room was thick with her scent — vanilla lotion, floral notes, and underneath it all, the warm, addictive musk of her body. Her hamper sat by the closet, and right on top like a deliberate offering lay a little black thong.

I snatched it with trembling fingers. The fabric was still warm, so fucking warm from her skin. I pressed the damp crotch to my face and inhaled deeply.

It was still wet with her fresh juices, carrying that sweet, slightly tangy, utterly addictive scent of her pussy. My cock throbbed violently as the rut surged through me.

I rushed back to my room, closed the door, and stripped quickly. My thick erection sprang free, heavier and more swollen than usual because of the heat. I wrapped Ruby’s warm thong around my fist and brought the soaked crotch back to my nose, inhaling her scent until it clouded my mind.

I imagined her in the shower — water cascading over her naked body, soap sliding over her perky breasts, her hands trailing down her flat stomach and between her thighs to that smooth, hairless slit.

I wrapped the silky thong around my aching cock and started stroking, the fabric creating a slick, delicious sheath that made me feel even closer to her.

I fucked my fist harder, imagining it was her tight, wet pussy, and the pleasure built rapidly inside me as low growls escaped my throat.

I was completely lost. The world narrowed to nothing but her intoxicating scent in my nose, the burning heat in my hand, and the vivid image of Ruby staring at me with that bratty, knowing smirk. I pumped faster, soaking her thong with my precum, my hips jerking wildly off the bed. I was right on the edge, about to explode, when—

My door swung open.

I froze. Ruby stood in the doorway, fresh from the shower with damp hair clinging to her shoulders and nothing but a thin towel wrapped around her body. Water droplets glistened on her collarbone.

Her eyes widened, then dropped straight to my cock, still wrapped tightly in her black thong, my hand frozen mid-stroke.

I yanked the blanket up in panic, but it was too late. She had seen everything.

I expected disgust. Horror. A scream. Instead, her soft pink lips curled into a sly, delighted smile. Her playful brown eyes lingered on the tent in my blanket before rising to meet mine.

“Wow,” she murmured, her voice low and teasing. “You really are a fucking pervert.”

Her tone wasn’t angry. It was delighted, curious, and full of mischief. She stepped inside, closed the door behind her, and walked straight to my bed, sitting on the edge so the towel tightened around her chest.

“I knew you’ve been doing this,” she said, leaning forward with a soft giggle. “My thongs kept disappearing from my hamper… and they always came back used. I’ve been waiting to catch you.”

I stammered uselessly, “Ruby… I’m sorry, I—”

She cut me off with another playful giggle. “You’re so fucking nervous. It’s cute.” Her eyes flicked back down to my blanket. “But I don’t know why you keep jerking off with my panties instead of just fucking me.”

My cock surged back to full hardness instantly. Ruby smirked at the reaction, then slowly let the towel around her chest fall, exposing her perfect breasts.

My breath caught. They were small, supple, and perky, with delicate pink nipples already stiff. She stood up, let the rest of the towel drop, and did a slow twirl, showing me her smooth, tight ass and her completely hairless, glistening pussy.

She stepped closer, grabbed the edge of my blanket, and yanked it away. My thick cock sprang free, still partially wrapped in her thong. Ruby’s eyes widened with hunger.

“Mmm… it’s so big,” she breathed.

She climbed onto the bed, turned around, and settled into a perfect sixty-nine position, her dripping pussy hovering above my face while her mouth hovered over my cock.

“I’ve been waiting to play with this,” she purred, pulling the thong off me. “Let’s see if I can make you feel better than my panties can.”

She licked the precum from my tip, then slapped my cock against her cheek and grinned at me. “You like that, perv?”

I slapped her ass hard enough to make her squeal, then buried my face in her pussy while she took me deep into her hot, wet mouth.

She ran her fingers through my hair in a possessive, gentle way, then looked down at me with pure lust burning in her eyes.

“It’s my turn to cum now,” she said, her voice husky and demanding. “You have to make me cum first if you want to fuck me, okay?”

Her words were a promise, a threat, and the sweetest gift. Without waiting, Ruby lowered herself, pressing her tiny, wet pussy directly onto my mouth.

The moment her slick, smooth folds touched my tongue, my wolf went completely feral. The rut surged through me like wildfire, making me growl loudly against her dripping cunt as I devoured her with raw hunger.

I licked long, greedy strokes up her slit, savoring her sweet, addictive taste while my hands gripped her ass tightly, pulling her harder against my face.

Ruby moaned loudly and started grinding on me, rolling her hips in needy circles. “Oh fuck… yes,” she whimpered. “Eat your stepsister’s pussy like that.”

I was lost in her. I sucked her swollen clit between my lips, flicking it rapidly with my tongue while pushing two thick fingers deep into her impossibly tight hole.

She was soaking wet, her juices coating my chin and dripping down my neck as the rut made me even more aggressive.

Ruby’s moans grew louder and more desperate. She rode my face harder, her small perky breasts bouncing as she used my mouth for her pleasure. Her thighs trembled around my head.

“Shit… you’re so good at this,” she gasped. “I’m already so close…”

I growled deeply into her pussy, the vibration making her whole body shake. I curled my fingers inside her, rubbing her g-spot while sucking harder on her clit. Ruby’s breathing turned ragged and broken.

“I’m cumming— fuck, I’m cumming!” she cried out.

Her pussy clenched violently around my fingers as she came hard, flooding my mouth with her sweet release. She kept grinding through her orgasm, riding my tongue until her legs shook uncontrollably.

When she finally lifted herself off my face, she was flushed and breathing heavily. She looked down at my cock — rock hard, throbbing, and with my knot fully swollen from the intense rut.

Ruby bit her lip, eyes dark with lust. “I want it,” she whispered. “I want that big wolf cock and your knot inside me.”

She moved down my body, straddled my hips, and rubbed my thick cock along her soaked slit before slowly sinking down onto me.

We both groaned as her tight pussy stretched around my length. When the swollen base of my knot pressed against her entrance, she let out a shaky, needy moan.

“Fuck… you’re stretching me so much,” she breathed.

The rut took complete control. I grabbed her hips and started thrusting up into her hard and deep. Ruby cried out in pleasure, bouncing on my cock as her tight walls squeezed me. We fucked like animals — intense, wet, and filthy.

I flipped her onto her back, pushed her legs up toward her shoulders, and slammed back inside her. Ruby screamed in ecstasy, her nails digging into my back as I pounded her mercilessly.

“Knot me,” she begged, voice breaking. “Give me your knot!”

With a deep, savage growl, I forced my thick, swollen knot past her tight entrance and locked us together. The feeling was overwhelming.

My knot swelled fully inside her, stretching her pussy to its limit as I came violently, flooding her womb with thick, hot ropes of cum. Pulse after pulse, far more than any normal man could give.

Ruby came again hard from the intense pressure, her pussy milking every drop from my cock as she shook and moaned beneath me.

We stayed tied together for a long time, panting and trembling. When my knot finally started to go down, I pulled out slowly.

A huge rush of my cum poured out of her stretched, ruined pussy onto the sheets.

Ruby looked up at me with a dazed, satisfied smile and whispered breathlessly, “We’re definitely doing that again before the full moon.”
