Summoned as an Infinite Evolution Hero with My Yandere Stepsister

I couldn’t hold back any longer. The sight of Alice bent over, back deeply arched and her plump ass spread wide with both hands, her soaked pussy clenching and dripping with need, completely broke me. I gripped her wide hips firmly and rubbed the thick head of my cock along her slick folds, teasing her entrance for just a second.

Then I thrust forward hard, burying myself to the hilt in one powerful stroke.

"Nnnghhaaa—!!" Alice cried out sharply, her voice echoing through the warehouse. Her tight, scorching walls stretched around my thickness, fluttering wildly as she took every inch. Her back arched even deeper, pushing her ass back against me until my hips slapped loudly against her soft, full cheeks.

She was burning hot and soaking wet, her inner muscles gripping me like they never wanted to let go. I pulled back almost all the way, then slammed in again, setting a deep, punishing rhythm right away. The loud, wet sounds of my cock pounding into her drenched pussy filled the entire space — heavy slaps mixed with constant, filthy squelching.

Alice’s massive breasts swung heavily beneath her with every brutal thrust, her long white hair bouncing wildly. She pushed back eagerly, meeting every stroke, her plump ass rippling beautifully against my hips.

"Kuro—! Yes—! Fuck me harder—! Destroy my pussy—!" she moaned shamelessly, voice already hoarse with pleasure. "Deeper—! I want to feel all of you—! Fill me up—!"

I reached forward and grabbed a thick fistful of her white hair, yanking her head back as I drove into her even harder. My other hand stayed locked on her hip, fingers digging into her soft flesh. Every powerful thrust made her cry out, her tight cunt clenching and fluttering greedily around my shaft.

From the corner of my eye, I noticed Seorin. She was still facing away, but her posture had completely crumbled. Her shoulders shook visibly. One of her hands had drifted down between her tightly pressed thighs, subtly pressing and rubbing against herself through her clothes. Her ears were burning crimson, and her breathing was fast, shallow, and ragged. She was trying to stay quiet, but I could see the small, desperate rolls of her hips as she fought the urge to do more. A soft, stifled whimper escaped her: "Haa... nnh..."

The realization that she was secretly touching herself while listening to me fuck Alice sent a raw spike of heat straight through me. My cock throbbed harder inside Alice’s dripping heat.

Alice noticed too. A wicked, possessive laugh escaped her between broken moans.

"She’s touching herself... haaah—! Can you see her, Kuro—? Nngh—! She’s getting off on the sound of you ruining my pussy—! Fuck me louder so she hears everything—!"

I growled and slammed into her even deeper, changing the angle to grind against that sensitive spot inside her with every thrust. Alice’s legs started shaking violently. Her pussy spasmed hard around my cock, squeezing me like a velvet fist as fresh juices gushed down my shaft and dripped onto the floor beneath us.

I kept pounding her without mercy, the loud impacts echoing through the warehouse. Her heavy breasts bounced wildly, her plump ass rippling with every savage collision. I released her hair only to reach around and grab one of her swinging tits, squeezing the soft, heavy flesh roughly while pinching her stiff nipple.

"Ahhn—! Kuro—! I’m— I’m going to—! Cum inside me—!" Alice’s voice cracked as her orgasm crashed over her.

Her entire body convulsed. Her pussy clamped down on my cock with powerful spasms, milking me as she squirted hard. A hot jet sprayed around my thrusting shaft, soaking my balls and her own trembling thighs. She screamed my name, walls fluttering wildly as wave after wave tore through her. "Kurooo—! Yes—! I’m cumming so hard—!!"

I didn’t slow down. I fucked her straight through her climax, riding out every contraction until her legs nearly gave out. Only then did I pull out, my cock glistening with her cum.

I flipped her onto her back on a stack of nearby crates, spreading her legs wide. I climbed between them and buried myself inside her again in one deep thrust. Alice’s eyes rolled back, mouth open in a silent cry of overwhelming pleasure.

In this new position I could see her face clearly — flushed, lost in ecstasy. I leaned over her, capturing one bouncing breast in my mouth while I fucked her with long, powerful strokes. Her legs wrapped tightly around my waist, pulling me deeper as she moaned loudly.

Seorin’s soft, broken whimper reached us again. I glanced over. Her hand was moving more obviously now between her thighs, rubbing herself faster while her other hand braced against the wall for support. She was still trying to be discreet, but her hips were rolling helplessly against her fingers.

Alice noticed and grinned through her moans.

"Look at her... haaah—! She’s fingering herself while you fuck me—! Nngh—! Harder, Kuro—! Let her hear how much I belong to you—! Make me scream—!"

I growled and picked up the pace, slamming into her soaked cunt with raw intensity. The crates creaked beneath us. Alice’s heavy breasts bounced wildly between us. I switched to her other nipple, sucking hard while my hips drove forward relentlessly.

After several minutes of intense fucking, I pulled out again and sat on the edge of the crates. Alice immediately understood. She straddled me eagerly, facing me, and sank down onto my cock with a long, broken moan. Her massive breasts pressed against my chest as she started riding me, rolling her hips in deep, sensual circles at first, then bouncing faster.

Her tight pussy swallowed me completely with every downward motion, her juices coating my shaft and dripping down my balls. I gripped her plump ass with both hands, helping her bounce harder, guiding her movements as her heavy tits slapped against my chest.

Seorin’s breathing had grown even louder. She had turned slightly, no longer fully facing away. Her hand was clearly inside her pants now, moving frantically as she watched us. Her thighs trembled, knees weak.

Small, stifled whimpers escaped her lips: "Haa... fuck... ahh..."

Alice leaned back, bracing her hands on my thighs, giving me a perfect view of her bouncing breasts and the way her soaked pussy swallowed my cock again and again. She rode me with wild abandon, ass slapping loudly against my lap.

The tension in the warehouse was electric. Seorin’s soft, desperate whimpers mixed with Alice’s loud moans and the constant wet sounds of our bodies colliding.

I suddenly stood up, still buried deep inside Alice. She wrapped her legs around me as I fucked her standing, bouncing her on my cock with powerful thrusts. Her arms clung to my neck, breasts bouncing heavily against me as she moaned right next to my ear. Every deep plunge made her juices run down my thighs.

After a few intense minutes like this, I set her down and turned her around again, bending her over the crates. I re-entered her from behind, fucking her even harder than before. Alice’s legs shook violently. Her pussy clenched and fluttered around me as another orgasm built rapidly.

Seorin was openly rubbing herself now, no longer trying to hide it completely. Her eyes were half-closed, lips parted, breathing ragged as she watched me pound Alice senseless. A choked moan slipped out: "Nnh... haa..."

Alice’s voice cracked with pleasure. "Kuro—! I’m cumming again—!!"

Her pussy spasmed hard around my cock as she came, squirting messily down her thighs. I fucked her through it, then pulled out suddenly.

Alice dropped to her knees instantly, knowing exactly what I needed. She looked up at me with glassy, lust-filled eyes, mouth open and tongue extended.

I grabbed her hair and pushed my glistening cock between her lips. She took me deep immediately, sucking hungrily, cheeks hollowing as her tongue swirled around my shaft. Her hands stroked the base frantically while she bobbed her head, taking me into her throat with wet, desperate sounds.

The sight of Seorin desperately fingering herself while watching pushed me over the edge.

"Alice—!" I groaned, voice rough.

Thick, powerful ropes of cum erupted straight into her mouth. Alice moaned loudly around my cock, swallowing greedily as I pumped rope after rope down her throat. She kept sucking and milking me with her tongue, not wasting a single drop, her eyes locked on mine the entire time. A few stray strands escaped the corners of her lips, dripping down her chin as she struggled to take everything.

When I finally finished, she pulled back slowly, a thin string of cum and saliva connecting her swollen lips to my cock. She licked it clean with a satisfied, possessive smile, then swallowed one last time, showing me her tongue proudly.

Alice licked her lips sensually, voice hoarse but triumphant.

"All mine..."

Behind us, Seorin let out a soft, broken whimper as she reached her own quiet climax, body trembling against the wall, hand still buried between her thighs.

The warehouse fell into a heavy, heated silence, filled only with the sound of our ragged breathing.
