Chapter 39: Step-Sister x Brother [2] (R18)

With a hungry growl, I grabbed my step-sister by her raven locks and grabbed her face, pushing my cock against her soft lips, the dark tip of my cock, pulsing with a sticky fluid that began to smear all over her face, with a strong, musky scent as she slowly recovered from the shock, her lips opened... allowing my cock to enter her mouth.

The warm, sloppy sensation of my sister's mouth... I couldn't control myself anymore, fucking her face as her cheeks puffed out, the warm saliva running down her chin.

My mind was already completely gone, focusing on the pleasure of her warm and wet mouth... I pulled out my cock, placing the tip against her lips and dripping a big string of precum onto her tongue. "Swallow it; enjoy the taste of the cock that will make you a woman."

She swallowed, her tongue licking my glans, her eyes still full of tears... and her look was pure lust.

My sister kneeled on the ground between my legs.

"It's time... Brother, Let me show you what a real woman can do." She grabbed my shaft, guiding it towards her pretty lips... Her hot tongue caressed my girth, licking the precum accumulating in my cock; she kept licking, sliding her tongue over my shaft, cleaning every bit of precum with a smile, like licking a lollipop.

Her pretty lips parted, opening wide as she took my head into her warm, moist mouth, her tongue swirling around it, her pink lips suckling gently before sliding down, trying to swallow my shaft.

"Aaa..."

"Mmmnph~ Unnnmm.... Nnnnph."

My groans and the wet slurping sounds of my sister were the only noise in the room.

With lustful eyes, I looked down at my sister, my member pushing into the back of her throat, my knot entering her warm cavern, the heat of her body enveloping me, the feeling of her tongue dancing underneath my cock, swishing her warm, drool like a heated pool for my shaft... her hands, caressing my thighs, while she tried to push further down, gagging slightly.

The warm, soggy feeling of the sloppy bubbling of her insides felt amazing as the tight flesh tightened and loosened around me... her eyes locked with mine.

I didn't need to move... the girl's body was doing the work, her mouth sliding up and down my cock, her tongue working on the underside, her hand stroking what she couldn't swallow, her pink fingers were shiny, her juices covering them.

My knot kept trying to enter her mouth; the sight made me lose control... it wasn't enough.

I needed more, holding her raven strands, forcing her down... my sister's eyes widened at the force behind my cock, fighting against her gag reflect, her saliva oozing through her lips, some tears running down her cheeks... a bulge appearing in her throat as I pulled back her head and forth, not caring about her wellbeing anymore, my body begging for release.

She let go of me, coughing, a string of saliva connecting my cock with her lips... gasping for air, my cock still standing in its mightiness before her; a fire had been ignited inside of me, an animal desire, and I was going to satisfy it.

"If you can't continue... it doesn't matter; we will have plenty of opportunities." I pushed her again against my throbbing manhood; her tongue slid along its length before engulfing it.

I grasped Aki's hair and, this time; I didn't stop using her like a sex toy... moans left her lips, her hands reaching for her pussy, sliding a finger inside while fingering herself, her moans muted by my meat rod filling her throat as she quivered. The more I became rough, the hornier and more responsive her blowjob became... My cute little sister was such a degenerate bitch...

My heart raced each time her lips kissed my knot; her eyes shone with a ferocious light... she, too, seemed to have a beast inside her... my beast.

"Sis, here it comes!!"

The warmth spread through my entire being... with a groan, I ejaculated inside my sister's throat, shooting multiple heavy spurts of sticky cum, my cock growing bigger because of my knot.

My cute Aki... who had barely become a woman, couldn't contain it all; thick, dense cum spurting out from her nose, some escaping her lips, some hanging from her chin while she kept sucking my cock, trying to swallow my essence... her body trembling, the spasm making her fair skin sticky and drenched with a mixture of drool and sperm.

My sister sat, hugging herself; the tremors went through her whole body as a low moan escaped her lips, her hips buckling up while riding her first orgasm caused by the taste of semen.

Like she was in a trance, her lips kissed and sucked the throbbing knot, filled with veins as it pulsated in her soft mouth as she snorted the cum that oozed from her nose back into her mouth.

The view made my cock stand erect, ready to unleash my canine libido on my dear Aki.

But before that, I wanted to make her ready...

Lifting her was too easy now since I had begun changing; my hands placed her on the black leather chair, lifting both of her legs and wrapping them over the arms, the position just like when I caught her masturbating and calling my name as she squirted across the room with a blissful face.

"Aki...." Her dreamy eyes looked at me with a happy look. "Brother... it was so delicious, a cock just for Aki~ look... Ugh..." She opened her mouth, guzzling and gargling with her mouth wide, my sperm bubbling like an erotic pornstar, before she sucked it up and gulped it down.

Aki then showed me her white tongue after... as if waiting for praise.

I knelt in front of her pussy... its beautiful pale colour made me lick my lips; a succulent delicacy... the delicate pink labia covered her precious maiden flower, surrounded by thin, black hairs.

The lewd scent was arousing; my wolf side unleashed as I licked her... Aki's cunt was more sensitive than I could ever imagine; her body trembled at the slightest touch.

Was it because of my new race? The taste was nothing like my ex-girlfriend, no slightly sour, flat taste... with a hint of salt, but an addictive and delicious taste.

"Mmmn!?"

Her hips began to bounce on the chair, my arms holding her legs far apart, revealing her cute pussy and puckering asshole, as my tongue began to slowly slide along her entire slit, the warm, squishing texture and sweet slimy juices causing me to feel aroused more... It seemed that my tongue was much longer and more flexible as I began to flick her hidden clit with my tongue, teasing the tiny hood hiding its true form.

Aki moaned loudly, grabbing her tits as she started pinching her nipples.

My saliva mixed with my sister's secretions, which began to overflow, moistening the chair, a hot liquid sensation... my tongue went inside, her muscles sucking me like her mouth had moments ago; the warm sensation enveloped my tongue.

I lapped Aki's pussy; my lips sucking the area while nibbling the edges... the delicious juice running down my throat, mixing with her drool, my sister's cries of pleasure as her cunt clamped down on my tongue with each soft cry, and her hips pushed towards my hungry mouth, seeking even more satisfaction.

She couldn't endure it anymore, letting out a squeal, her inner muscles twitching uncontrollably, and a thick, viscous liquid overflowing, splashing all over my face and falling on the wooden floor... Aki climaxed for the second time... and her day hadn't finished yet.

"Brother! Oh~ Fuck, It feels too good!! Please, make Aki a woman; breed this slutty sister like your little bitch!"

I stood up, staring down at the mess her fluids and my tongue had caused... my canine lips shining with her fluids while her pussy gleamed with her sticky lubricant.
