The Heat-Crazed Bitch Sister Who Can't Live Without Her Brother's Cum

I crushed Beatrice's severed arm under my combat boot where it lay sprawled on the floor and strode deeper into the cave.

Wooden crates the bandits had stolen were piled high like a mountain.

I kicked one hard. The lid shattered and gold and silver coins spilled across the ground.

Jewels and glittering ornaments of every kind caught the torchlight and flashed.

"This much could swallow a whole territory without breaking a sweat."

I wiped the blood from my chin with the back of my hand.

Behind me came the soft splash of water.

"I-Ian... h-here... there's groundwater pooled up..."

Seria called to me in a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠trembling voice.

I turned.

At the deepest point of the cave, beneath the rock wall, a fairly wide underground pool had collected.

I stripped off every scrap of my filthy clothes and flung them aside.

The blood-caked boots I kicked away without a second thought.

Completely naked, I sat on the edge of the pool.

"Come wash me."

Seria flinched like a frightened puppy, then carefully approached.

Her clothes were already torn and ruined in so many places she might as well have been naked.

Her heavy breasts swayed roughly with every step.

She dropped to her knees and soaked a scrap of torn cloth in the water.

Her pale hands began carefully wiping my back.

"Scrub harder. Don't leave a single bloodstain."

"Okay... I got it..."

Seria put strength into her hands and rubbed my shoulders and the muscles of my back.

The cold water touched my skin, but my body stayed hot.

Reaching Level 12 had skyrocketed my physical abilities.

Above all, the massive cock pillar between my legs still stood iron-hard, refusing to die down.

"Now the front."

I turned so I faced her directly.

The moment Seria's eyes landed on my huge thing, her shoulders heaved hard.

The sound of her gulping was loud and clear inside the cave.

"Hurry up and wipe."

"Hnn... yes..."

She rubbed my firm abs with the wet cloth.

Her breathing grew rougher little by little.

The thick male scent and the reek of blood rolling off me teased her nose.

I looked down and studied her body.

The pure white skin showing through the rips in her clothes was flushing red.

Especially the nipples at the tips of her swollen breasts—they stood stiff enough to poke right through the fabric.

I reached for those tits.

My big hand roughly seized one full breast and squeezed.

"Ah!"

Seria jerked in surprise and twisted, but she didn't run.

"What are you thinking right now?"

"N-nothing... really, nothing..."

Her emerald-green eyes darted around in panic.

I kneaded the breast I held like a lump of clay, mercilessly.

"Nothing, huh? Then why are your nipples this hard? Already in heat?"

"N-no... that's... because it's cold..."

"Lie."

I dug my nails in and twisted her stiff nipple hard.

"Aaaang! It hurts... Ian... it hurts..."

Seria squeezed out tears and grabbed my wrist.

But her legs were already twisted together.

I could clearly see the insides of her thighs trembling.

Watching her reaction, I smiled with interest.

This time I decided not to use the skill.

I wanted to see exactly how this bitch's vulgar body would respond to me without the cheat skill Forced Orgasm.

Could I make her cunt drip just by twitching a single finger?

"Let go."

I knocked her hand off my wrist.

Then I shoved her shoulders and laid her on the floor.

Seria stared up at me with startled eyes, her back against the cold cave stone.

"Strip everything."

"I-Ian... here...? Over there... Mom's..."

"Did you not hear me? I said strip. Right now. Before I tear it off you."

With shaking hands Seria hurriedly flung away the last scraps of cloth.

In an instant her lush, dazzling naked body was bare under the torchlight.

Breasts ready to burst and a sensual hip line—perfect.

Her thighs were firm and delicious.

I locked my gaze between her spread legs.

"Spread them wider."

Face burning with shame, Seria opened her thighs wide to either side.

Her smooth, hairless pussy lips were fully exposed.

The entrance was already wet and glistening.

"Your cunt's leaking like a faucet. Seeing your little brother's ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠cock after he just cut off the bandit chief's head got you that horny?"

"N-no... hnn... ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠this is just... my body being weird..."

"Excuses while your cunt hole gapes like a whore."

I pressed two fingers together and roughly rubbed her soaked pussy lips.

"Hyaaat! Hn! Aaa..."

Seria arched her back like a live fish and moaned.

I coated my fingertips thickly in her slippery juices and scrubbed hard over her stiff little clit.

"Aaaaang! I-Ian! There... that's too...!"

"Too what? Want me to rub it harder?"

I made my fingers faster and more violent.

I crushed and dug into her pussy flesh.

Squelch, squelch.

Obscene wet sounds filled the cave.

"Haang! Haaat! Ah! Aaaa!"

Seria's head fell back.

Both her hands clawed at the dirt floor.

Even without using a single skill, her body reacted violently to every touch of my hand.

Her cunt hole was already twitching as if it wanted to swallow my fingers whole.

I shoved two fingers deep into her hottest place.

"Aaaak! Hyaaang!"

Her insides writhed and clamped hard around my fingers.

I hooked them and roughly scraped down her vaginal walls.

"Ah! Aaat! Hn! Crazy... I'm going crazy... Ian...!"

"Your cunt's seriously filthy, sis. Two of your little brother's fingers and you're already thrashing like this? When my cock goes in later you'll black out for sure."

I mercilessly thrust and twisted my fingers, relentlessly targeting her weak spots.

Squelch! Squish!

Every time my fingers went in and out, white juices spurted from her pussy.

"Haaa... haa... pull them out... please pull your fingers out..."

Seria begged through tears.

Her eyes were already half-glazed.

"Why? Fingers not enough? Begging me to shove the real cock in already?"

"N-no... aaa... I don't know... I don't know either..."

"Say it honestly. You want your little brother's cock to fuck you."

I stopped my fingers and whispered right against her ear.

Seria shook her head hard, trying to resist.

"I-I can't say it... how could I say something like that... hn..."

"That so? Then I'll just finger-fuck you for the rest of your life."

I started to pull out, then slammed back in like a beast.

"Aaaaang!! Ah! I'll say it! I'll say it so stop...!"

She screamed and desperately clung to my arm.

"Say it."

"I-I want little brother's cock... Ian's cock... please shove it in me..."

Seria bit her lip in shame and spat out the filthy line.

I smiled in satisfaction.

"Good girl. As a reward I'll fill you with cum till your belly bursts."

I hooked her thighs up over my shoulders.

Her cunt hole gaped wide open right in front of my eyes.

I lined up my swollen, ready-to-burst cock against her entrance.

"Open up."

Seria squeezed her eyes shut and lifted her hips a little.

Without hesitation I slammed my hips forward hard.

Thwuck! Squish!

"Aaaaaaaaaak!!!"

My massive cock tore straight through her tight, hot vaginal walls in one brutal thrust.

A ripping scream burst from her mouth.

Her insides stretched taut and squeezed my cock pillar so hard it was hard to breathe.

When I bottomed out in one go, her lower belly bulged outward.

"Khh... fuck... you're clamping so goddamn tight. Trying to snap a man's cock off?"

I gritted my teeth, crushed her breasts under my hands, and started pounding my hips.

Thud! Thud! Thud! Thwack!

"Aaaang! Haaang! Ah! Aaat!"

The savage sound of flesh slamming flesh echoed mercilessly through the cave.

I shook my hips rough and violent like an animal.

No skill needed.

Squelch! Slap! Slap!

"Haaa... too... too big... my belly... it feels like it's going to tear..."

Seria thrashed her head side to side and wailed in ecstasy.

Every time my cock pillar pulled out and slammed deepest, her whole torso jerked off the floor.

"So what if it tears. Fill a torn cunt with cum and you'll still cream yourself crying for more, you bitch."

"Aaa! No... hyaaang! Th-there... ah!"

Her eyes rolled white and drool spilled from the corner of her mouth.

From deeper in the cave came a rustling sound.

I glanced over. Margaret was on her knees behind the torchlight, watching us.

Both her hands were buried between her own legs.

She was finger-fucking herself while watching her son rape her own daughter like a beast.

"Mom. Stop finger-banging yourself over there and come closer. Watch how tight your daughter's cunt hole is."

I shouted at Margaret.

She crawled over on all fours until she was right beside us.

She pressed her face close to Seria's thrashing thighs.

"Haa... haa... my daughter... Seria..."

Margaret panted hot breath and muttered.

"Cheer her on, Mom. Tell her not to spill a single drop of her little brother's cum—swallow it all deep in her belly."

I sped up my hips even more as I ordered.

Thud! Thud! Squish! Squelch!

"Seria... Seria... sob... it's from Ian so... you have to take every last drop... understand? That's how we stay alive..."

Margaret whispered to her daughter in a completely broken voice.

"Aaaa! Mom! Mooom! Haaang! Something's wrong with me... it feels too... good..."

Seria sobbed hard and reached a hand toward her mother.

"You filthy twin bitches. Both of you so deep in heat you're going crazy as a set."

I locked Seria's legs tight around my waist, roared like a beast, and poured on the final sprint.

I slammed my cockhead into her cervix like I meant to smash it.

Thwaaaack!! Thud! Thud!

"Kyaaaaang!! Ian!! Coming!! I'm gonna come!! Aaaaaat!!"

Seria's whole body went rigid as if struck by lightning.

Her cunt convulsed madly, clamping my cock so hard it felt ready to snap.

Hot juices gushed out like a waterfall and soaked my crotch.

I hit my limit too.

The thick red lust coiled in my groin exploded all at once.

"Fucking bitch. Swallow it!!"

I buried myself to the absolute root and held still.

Brrrrrrrr!!! Sssssss!! Gulp! Brrt!!

Semen hot and thick as lava blasted straight into Seria's womb.

It filled her completely and began to overflow.

"Hiiiik!! Aaaaa!! H-hot... inside my belly... so ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠hot...!!"

Seria's eyes rolled back as she clutched her stomach.

Her lower belly, already bulging, swelled even fuller, ready to burst with cum.

I emptied every last drop of my seed into her belly without holding back.

The gulping pulses traveled up through her stomach and into me.

A red status window floated in the air.

At Level 12 a massive amount of experience poured in, but it still wasn't enough to level up.

What mattered was that I had perfectly proven physical corruption.

This bitch was completely mine now.

I slowly pulled my cock out of Seria's belly.

Squelch... pop.

"Haa..."

From her gaping cunt hole the huge load of cloudy cum I had pumped into her gushed out in thick pulses.

She stared at the ceiling with a completely vacant expression, just panting hard.

Her thighs were a sticky mess of semen and juices.

Margaret, who had been watching from the side, stuck out her tongue and began lapping up the cum running down Seria's thighs.

"Mm... my son's scent... so hot..."

Margaret's eyes were completely rolled back.

I looked down at the two sprawled women and picked up my clothes.

I was ready to leave this blood-reeking cave behind and step out into a bigger world.

"I finished cumming, so get up. Pack the loot."

I ordered them coldly.
