------------------------------
I was assaulting my step sister with my eyes as she stood in front of me, looking up her thick long legs, past the scuff marks on her knees to her black panties which were being partially swallowed by her thighs. I only had a second to see the glistening mess her excitement had caused her before I spoke.
"Didn't you have plans with your friend tonight?" I asked my flame haired step sister with a slight chuckle in my voice.
Alanah responded with a giggle of her own, letting her skirt cover her privates as she moved her hands to cling to her wide hips. "Yeah...She'll understand when I tell her." She gave me a quick, hungry look up and down before she began to move toward the bathroom, allowing her thick thighs to rub against one another with each ass popping step. "You coming Stud? Or do I have to drag you in here with me?" She called out with a playful laugh. Moments later I heard the shower blaze into life, staring its pitter patter of enflamed water.
I stood up moments later, pulling my shirt over my head and letting it drop onto the pile of my clothing that rested where she had pulled them off. Stepping up through the hall I heard those alluring, devilish giggles as the bathroom door moved slightly ajar. My heart raced, a wobble in my step as I approached. The bathroom had already steamed up with a dense fog of humidity, the water loudly shooting out of the nozzle onto Alanah. The clouded glass door was open wide, exposing her naked body to me. Her hair down from its tight ponytail and darkened due to the absorption of water.
A grin formed on my face, being able to see such perfection in my step sister...I stepped forward, closer and closer as my glistening cock swung heavily left and right. I examined her body like it was a fine work of art: a large, perky bust that were well more than a handful, an ass so soft looking that it would be good enough to eat...seeing her without clothes was enough to bring the beast back out of hiding.
She turned her eyes to me, watching as my swaying cock shifted with my movements, she brought her hands up to her hair and pushed it back, her wet heft now ran down her back toward that mouth-watering ass. Those cum ridden hands slid down her tits, giving her erect nipples a slight pinch before she traced her fingers down the bulge in her toned stomach; not able to contain herself after all the excitement, she let one hand slip lower, pushing between her thick thighs before finding her wet, cock craving lips. Feeling a shudder of release running up her arched back she pushed a finger between her lips, gasping a little.
"Come here you fucking hunk." She beckoned with lust.
I stepped one foot into the shower with her...pushing my body through the open door to join my step-sister in the hot shower. I felt her hand reach behind to roughly take my hand, pulling me into her. My hardening cock was nestled perfectly between her juicy ass cheeks as our fully nude bodies pressed onto each other. I felt the blood pump back into my horse dick as fast as lightning, pushing up longer and thicker with each pump of blood that pulsed into it; the exposed tip pressed onto my gut as she forced us to push against each other.
Tilting her head back to rest on my shoulder, Alanah let out a sigh, her body shook against mine as she gave her clit a quick flick.
"Don't ever leave a woman wanting, if she makes you cum, you have to return the favour." Her voice was rushed in her explanation, her body now demanding to feel a full release. Using my grip on my first hand, she brought it up to her tits, making me take a handful before pushing it around in small circles, letting me feel the weight of them. Her nipples poked firmly on my palm as I groped and squeezed her. A heavy moan escaped my lips, right next to her ear as I worshipped those huge tits.
Her second hand finally wrenched from between her thighs, quickly reached for my other hand. Wasting no time as she pulled my hand between her thighs, the warmth and slickness was immediate as her thighs squeezed down around my massive paw. With her hand on the back of mine, she guided me on what to do, silently praying that I head learnt how to do this from all the porn I had watched in my teenage years.
My head exploded as I felt Alanah's swollen, drooling lips. Going dizzy from the amount of sexual frustrations leave my body, I turned my head and roughly kissed my sister again, only this time it was me leading the charge; pushing my tongue down her mouth I started to rub her sensitive clit with my thumb roughly, whilst penetrating her cunt with two fingers. From my initial fingering I thought she was quite tight, given that a new man every night was very much on this ginger goddess' schedule I expected her to be as wide as a cave. The surprise was welcoming, as was my slow thrusts to push my cock up and down her jiggling ass.
Knowing she was getting close to being overloaded, Alanah slammed her pretty eyes shut, feeling the first touch of my manly hands on her womanhood. Not able to keep her mouth closed as a violent shiver rocked that perfect body, she let out a long, choked moan.
She was mid moan when she was met with my lips pressing into hers and my furious tongue swirling in her cock flavoured mouth. Desperate for a distraction, trying to keep this feeling for as long as she could, shed mixed her tongue against mine.
But nothing could keep her distracted from the movement between her thighs. Feeling the slow penetration of my strong fingers, the muscles relaxed to pull me in, her clit being pushed and rubbed by my thumb. It was all too much to keep up with, her bodies reactions taking over, her hands hungrily pushing mine against her to force me to play with her rougher. Her hips pushed back and forth to stroke my cock with her bouncy ass, her expert tongue greedily playing with mine as loud moans escaped her mouth.
The sound of the shower was not registering with me, neither was the scathing heat setting which my shower partner had set it to...All I was focused on was this amazing feeling of exploring my sister. Without much of a care if it was too rough, I push my fingers as deep as I could into her with one plunge, pushing my two fingers knuckle deep into her swollen hole. The moans between us vibrated in our mouth and escaping our furiously passionate, animalistic make out. I couldn't keep my hands off of this woman, she was like a drug, addictive and feeling so good. Thrusting my cock up and down on her ass along in rhythm with her motions caused my foreskin to peel back and forth, making my knees wobble and hands tense up on her.
She let out a muffled cry in my mouth, almost pleading as my rough push inside her made those legs quiver. I felt a sticky substance drip past my knuckle deep fingers and down my wrist where she had wrapped her hand around to keep me in position. Alanah couldn't recall the last time a guy had gotten her so wet.
I could taste the dregs of my potent cum on her lips, not caring if that was weird or not, I was too enthralled with the moment we were having. With the water cascading onto us heating our skin and body heat as we got dirty. I break the kiss for a moment, smiling as I now pushed my fingers out and in knuckle deep on her ever-tightening walls. When I pulled away, I saw her trying to move herself forward to follow my retreat, wanting to feel my lips on her for longer; she only managed to steal a quick lick of my bottom lip before I spoke.
"What would our parents think of us doing this?" I asked her with a bewildered tone; I in fact thought I was dreaming, and any moment now I was about to be woken up with more chastising and bitching. Alanah opened her eyes a took a hard blink, at first my question resulted in a deep blush and a sneaky smirk.
"I'd imagine my mom would stop paying us to live together...I'm sure your dad would call me a whore." She put on a deep pout he gave me a signature fake pitiful look before her facade breaks and that familiar alluring smirk returned "He'd be right." She followed the fact with a long pull of her ass up the length of my cock, tensing her ass to squeeze it tightly before pulling it back down.
Biting my lip, a moan escapes me, that feeling of that ass jerking me off was something I didn't even know a woman could do...as we pressed together that unmistakeable flow of clear stringy liquid spewed out of my shaft onto my sisters toned lower back. The exposed bulging head brushing over her ginger hair with each thrust of our hips. Feeling the now familiar warm stream of my pre-cum hit her back, the redhead let out an alluring giggle. It amazed her to no end just how relentless my manhood was. To attempt to make the sensitive head feel even better, she started to shake her head back and forth lightly, causing the tips of her hair to brush lightly over my sensitive head; a move that only made my pre-cum surge out even more, lacing into her silky, wet locks.
"Let's make sure they don't ever find out then Sis..." I dive my head into the nape of her neck, kissing and sucking on the smooth flesh like a vampire. I had heard about love bites, and had seen them all the time on campus. I wanted to leave my mark on her, if this was going to be a one and done thing...Alanah let out a soft laugh while she removed her hand from mine to run through my soaked hair. She knew exactly what I was doing.
"You want to show the world who I belong to Stud?" Her tone teasing as her hips bucked quicker on my relentless fingers. "Have all the men on my hook picturing me under you, your big dick buried deep inside me..."
