Summoned as an Infinite Evolution Hero with My Yandere Stepsister

"Kuro..." She bit my lip, then soothed it with her tongue. "Please~"

I gave in completely. My other hand slid down to the side of her robe, tugging the fabric aside. I pulled it open just enough for one full, heavy breast to spill out into the open air. The moment it was free, I leaned down and captured the stiff nipple between my lips, sucking hard.

Slurp... schlop...

"Ahhn—!!" Alice moaned sharply, her back arching sharply as she pushed her bare tit deeper into my mouth. "Yes...! Suck it like that... mmmh~! Your tongue feels so good directly on me... haa~"

I devoured the exposed breast, tongue swirling and flicking rapidly over the sensitive peak while my hand kneaded the soft, warm flesh possessively. Pop! I released it for a second only to latch on again even harder, sucking noisily. Her nipple throbbed against my tongue as I gently bit down.

"Nngh—! Kuro...! Bite it more... ahhn~ My tits are so sensitive today..." she whimpered, voice trembling with pleasure. Her hand finally freed my throbbing cock from my pants, wrapping her warm fingers tightly around the thick shaft. She started stroking me with long, firm movements, twisting at the head every time. Shlick... shlick... shlick...

"You’re already so fucking hard..." Alice breathed hotly against my ear, her eyes dark with raw lust as she pumped me faster. "Mmmh~ You wanted me this badly too, didn’t you? Since the last time... you’ve been craving my body just as much as I’ve been craving yours, huh?"

"Yeah..." I groaned, the word rough and honest. "I have. Fuck, Alice... I can’t think straight when you’re like this."

She smiled wickedly against my mouth as I pulled her into a deep, messy kiss. Our tongues tangled hungrily, saliva mixing as she moaned into me. For a moment her soft breasts pressed flush against my chest, nipples hard and slick from my mouth.

Then she placed both hands on my torso and pushed me back gently but firmly, breaking the kiss with a wet pop. Her eyes never left mine as she slowly slid down my body, robe hanging open, breasts swaying heavily with every movement.

Shit... she’s really doing this right here.

Alice dropped to her knees in front of me, her face level with my aching cock. She gave it one long, slow stroke, admiring the way it throbbed in her grip, then leaned in. Her hot breath ghosted over the sensitive head before she parted her lips and took me into her mouth.

Schlurp...

"Mmmph~" The wet, velvety heat of her mouth enveloped me as she sank down halfway in one smooth motion. Her tongue swirled around the underside while her hand stroked the base she couldn’t yet fit. She bobbed her head slowly at first, sucking noisily, cheeks hollowing with each pull.

"Ahhn—! Fuck, Alice..." I hissed, one hand instinctively threading into her white hair.

She pulled off for a second with a lewd pop, strings of saliva connecting her lips to my glistening cock. "You taste so good... haa~ I’ve been thinking about swallowing this thick cock again for so long."

Then she dove back down, taking me deeper, her throat relaxing as she forced more inside. Gluck... shlop... gluck... The obscene sounds echoed through the warehouse as she sucked me with eager, hungry strokes, her bare tits jiggling heavily with every movement.

Alice’s mouth was pure sin. She swallowed me deeper with each bob, her tight throat squeezing around the head of my cock. The wet, filthy sounds grew louder and more desperate, saliva dripping down her chin and onto her swaying tits.

"Mmmph—! Mmmh~" she moaned around my shaft, the vibrations shooting straight through me. Her tongue worked relentlessly, swirling and pressing along every sensitive inch while her hand twisted and pumped the base in perfect rhythm. She pulled back until just the tip was between her lips, sucking hard with hollowed cheeks, then plunged down again, gagging herself eagerly.

Shlorp—! Gluck-gluck-gluck!

"Fuuuck, Alice..." I growled, my hips twitching. This is insane. We’re supposed to be training, not—

My eyes flicked toward the back of the warehouse.

Seorin was still facing away, hands raised to maintain the wind shell, but her posture had completely changed. Her shoulders trembled. Her ears burned scarlet. Her thighs were pressed tightly together, and I could see the subtle, unconscious rolling of her hips as she fought the urge to grind against nothing. Her breathing was fast and ragged.

She’s hearing every single wet sound. Every moan. Every time Alice chokes on my cock. She might even be stealing glances from the corner of her eye...

The realization sent a raw, electric spike of excitement through me. My cock throbbed even harder between Alice’s lips.

Alice noticed the shift immediately. She pulled off with a messy pop, gasping for air, thick strings of spit connecting her swollen lips to my glistening length. "You’re even harder now... haa~ Is it because she’s listening? Because she can hear me sucking you so greedily?" She gave my cock a long, slow lick from base to tip, eyes sparkling with wicked delight. "Mmmh... then let’s give her something better to hear."

She dove back down without hesitation, sucking me with renewed, almost desperate hunger. Her head moved faster, taking me into her tight throat over and over. Gluck—! Gluck-gluck—! Shlorp—! Drool ran freely down her chin, splattering onto her jiggling breasts as she fucked her own face on my cock.

The sounds, the heat, the sight of Seorin’s obvious arousal in the background — it all pushed me dangerously close to the edge.

I couldn’t hold back anymore.

My hand tangled tightly in Alice’s white hair. I held her head firmly in place and started thrusting into her mouth, fucking her throat with deep, urgent strokes.

"Ahhn—! Mmmph—!!" Alice’s muffled moans grew louder, encouraging me. Her eyes watered but stayed locked on mine, eager and filthy.

I drove into her mouth harder, the wet rhythmic sounds filling the warehouse as my balls slapped against her chin. Seorin’s trembling shoulders and ragged breathing only fueled me more.

"Alice— fuck— I’m gonna cum," I groaned.

She moaned loudly around my cock in response, sucking even harder, desperate for it.

With a final, deep thrust I buried myself in her throat and came hard. Thick ropes of cum shot straight down her throat as my cock pulsed violently between her lips. Alice swallowed greedily, gulp... gulp... her throat milking every drop while soft, satisfied whimpers vibrated around me.

I held her there for a few long seconds, breathing heavily, before slowly pulling out. A thick strand of saliva and cum stretched between her lips and my cock as she gasped for air, looking thoroughly used and very pleased with herself.

Alice licked her swollen lips slowly, then caught the dangling string of cum with her tongue and swallowed it with a satisfied moan.

"Mmmh... still so fucking good, Kuro~" she panted, voice hoarse and dripping with lust. "Your cum is so thick and warm... I love drinking every drop of you."

She stayed on her knees for a moment, catching her breath, then rose gracefully. With a sultry look, she reached behind her neck and untied what remained of her robe. The fabric whispered down her body and pooled at her feet, leaving her completely naked.

Her massive breasts bounced heavily as they were freed, full and swaying with every small movement. Her waist curved dramatically into wide, fertile hips and a thick, juicy ass that made my cock twitch again despite having just cum.

I couldn’t help but glance toward the back of the warehouse.

Seorin was still pretending to focus on her magic, but she was clearly failing. Her shoulders shook visibly now. Her legs were pressed tightly together, thighs clenching and rubbing slowly against each other. Her ears were deep crimson, and her chest rose and fell rapidly. She was burning with arousal.

She’s hearing everything... every moan, every wet sound... and she’s losing it.

Alice noticed where my eyes had gone. She smirked and turned around slowly on purpose. She bent forward, arched her back deeply, and reached back with both hands to spread her plump ass cheeks wide open for me.

Her soaked pussy was on full display — puffy, glistening, and dripping wet. A shiny string of her arousal stretched downward.

"Kuro..." she begged, voice trembling with pure need, "please... fuck me. I’m so empty. I need your thick cock stretching me open right now. Please~ Fill me up."

I stepped closer, running my hands over her wide hips, feeling the intense heat radiating from her skin. "You really want me to fuck you right now, while Seorin is right there listening to everything?" I murmured, my voice low and rough.

Alice shivered hard and pushed her ass back against my cock, rubbing her soaked folds along my length.

"Yes... that’s exactly it," she answered breathlessly, voice full of possessive hunger. "I need her to understand exactly who you belong to, Kuro."

So she still hasn’t gotten over those close moments with Seorin... That’s why she’s acting like this. Territorial. Filthy. And way too turned on by it.

I glanced over at Seorin again. She hadn’t moved. Her back was still turned, but her whole body was visibly tense. She wasn’t stopping us. She was just enduring it, burning up in silence.

Alice noticed my gaze and spread her ass even wider with both hands, presenting herself shamelessly.

Her huge, round ass cheeks were soft and plump, perfectly spread to reveal her dripping pussy — swollen, shiny with arousal, and clenching visibly with need. A thick string of her juices slowly dripped down toward the floor.

"Please, hurry, Kuro..." she whined desperately, voice cracking with frustration and lust. "I can’t wait any longer... I’m going crazy. Please... fuck me now~"
