My Horny Stepmom Turns Me into Her Vampire Slave

Chapter 263: B - Claire’s true nature

Knock! Knock!

"Who is it...?" Claire asks lazily when she hears someone knocking on her bedroom door.

She’s lying on her stomach with her face buried in the pillow.

She’s still wearing the knee-high socks from her school uniform, along with a long white T-shirt that reaches almost below her butt.

Her expression is distant and thoughtful — she’s still shaken by what happened at the boutique that afternoon.

"Who do you think it is? There are only three of us in this house, and Hakuto went out to get groceries!"

Irina’s voice comes from the hallway.

Then she throws the door open and walks in without even waiting for permission.

The gesture immediately irritates Claire.

She takes her privacy extremely seriously — so much so that she made both Irina and their mother swear they would always knock before entering.

Standing in the doorway, Irina is dressed almost exactly like Claire — just an oversized T-shirt and panties, though without the socks.

"What do you want?" Claire grumbles, annoyed.

"Do I really need a reason to spend some time with my sweet, precious big sister?"

"Yes."

"Ugh... you’re such a pain! Anyway... I’m coming in!"

Irina doesn’t even finish the sentence before bursting into the room and pouncing on Claire.

She lands heavily on her back, making the bed shake, her enormous breasts pressing down against Claire’s shoulders.

"Just tell me what you want so I can go back to relaxing in peace. And get your boobs off me — they’re too damn heavy!" Claire grumbles in exasperation.

Irina doesn’t answer.

She pushes herself up until she’s straddling Claire, then drops straight down onto her sister’s soft butt and starts bouncing on it like it’s a hopper ball.

The entire mattress shakes, and so do Irina’s breasts, bouncing freely beneath her T-shirt without a bra to restrain them.

"I-Irina... stop it...!"

"You know, Big Sis... being a girl is great and all... but sometimes I really wish I had a nice big dick... and this is definitely one of those times!"

"D-Did you... seriously just say that...? Don’t you have even a shred of shame...?"

All of a sudden, Irina stops bouncing on her sister’s butt.

She presses her pussy against Claire’s ass and starts grinding against her.

Slowly at first, then harder and faster with each movement.

Claire’s soft, muffled moans grow along with the pace.

"W-Why do you keep denying who you are, Big Sis?" Irina asks, her voice no longer playful, but serious and pained. "If you keep this up, things like what happened today at the swimsuit shop, or in the hallway at Reimeikan High, will never stop. They’ll only get worse! I... I can’t live every day terrified that something horrible might happen to you just because you refuse to accept what you really are! I won’t stand by anymore while you put yourself in danger again and again!"

Large, heavy tears fall onto Claire’s back as Irina continues rubbing against her.

"Even if I have to use force... I’ll make you embrace your true nature! We already lost our father... I don’t want to lose you too!"

"Irina..."

Claire suddenly rolls over, ending up flat on her back with Irina still firmly straddling her.

She reaches up, grabs her by the shoulders, and pulls her into a tight embrace.

Irina’s tears keep falling, wetting Claire’s cheeks.

"Trust me, little sis," Claire whispers in a warm, reassuring voice, gently wiping away her tears with her thumbs. "I’ll find a way to fix this... without doing that. I promise."

Then Claire kisses Irina — a soft, fleeting touch of their lips.

"A... kiss?" Irina whispers, blinking. "You know what it means to seal a promise with a kiss, right...?"

"Who do you think you’re talking to? Of course I know! As if I’d ever forget the traditions of our ancestors!"

"Now go back to the living room — Hakuto is probably already home. And make sure you close the door properly," Claire orders.

Irina hops off the bed and gives her a salute like a little soldier.

"Yes, ma’am!"

◇◇◇

"Psst... Hakuto... wake up, Hakuto..." Irina whispers softly, shaking him by the shoulder.

On the large bed where Hakuto had been sleeping alone until just a couple of nights ago, Claire and Irina now lie beside him.

After what happened with Itsu, the three of them realized that sleeping in separate rooms was simply too dangerous.

But for Hakuto, sharing a bed with them presents an entirely different kind of danger.

He’s lying flat on his back, wearing nothing but a pair of shorts, with one stepsister on either side.

Claire has her back to him, lying near the edge of the bed, completely wrapped up in an oversized pajama set. She usually sleeps in lingerie — or naked when it gets really hot. But ever since the three of them started sharing a bed, she’s completely changed her sleeping habits, switching to long pajamas and even a pair of thick socks.

"I’d rather cook alive in my sleep than lie half-naked in the same bed as Hakuto!"

Irina, on the other hand, is lying on her side facing Hakuto. She’s wearing nothing but her underwear, and only because Claire forced her to — Irina would have happily gone without it.

Hakuto has already had to push her away twice that night. Both times, she clung to him like he was a body pillow.

"Irina... what do you want...?" Hakuto mumbles, still half-asleep.

"I have something really, really, really important to tell you. It’s about Claire."

That gets his attention.

Her tone is far too serious for one of her usual jokes.

"This better be important... or I swear..."

"It is! I’m serious!"

"Fine, go ahead..."

Hakuto sighs. Knowing Irina, it’s probably something stupid — but he’s already awake now, so he might as well hear her out.

"What happened at the swimsuit shop wasn’t just bad luck."

"I figured as much. Succubi have the power to charm men and make them do whatever they want."

"Yeah, that’s how it works. But come on, you know Claire. Do you really think she deliberately lured that old pervert in...?"

Hakuto frowns.

"Now that you mention it... yeah, that is pretty strange..."

"Succubi are demons who use sex and seduction as weapons, or to get what they want. But Claire is the complete opposite of what a succubus is supposed to be."

"Irina... it’s three in the morning. Don’t tell me things I already know. Get to the point," Hakuto grumbles, struggling to keep his eyes open.

"How was I supposed to know you already knew that?! You could’ve stopped me instead of letting me ramble on like an idiot!" Irina huffs. "Anyway. It wasn’t an isolated incident. Things like that happen almost every time we go out. Once, even at school, a teacher grabbed her by force and slammed her against a wall, squeezed her breast, and pressed his dick against her ass. The truth is, Claire can’t control her powers."

"Okay... and what exactly am I supposed to do about that?"

Irina suddenly moves closer.

Now they’re face-to-face — and her enormous breasts, barely contained by a tiny black bra, aren’t exactly helping Hakuto concentrate.

But beyond that, her expression is serious.

Far more serious than he’s ever seen her before.

"Hakuto. You have to..."

He swallows nervously.

A moment of silence. Then...

"...you have to take Claire’s virginity."

"I have to... WHAT?!"

Hakuto is about to tell her to fuck off, roll over, and go back to sleep, but the determination in his stepsister’s eyes makes him hesitate.

Normally, Irina would say something like that with her usual playful, perverted grin, but right now, there isn’t a trace of it in her eyes.

"N-No way... You can’t be serious...!"

"I’ve never been more serious in my life. Claire’s powers are going out of control because she’s still a virgin. Succubi usually awaken around the age of thirteen, but by that age, most of them have already forgotten what virginity even is. Not Claire. She’s spent too long in the human world. She thinks virginity is sacred and that she has to wait for the right person. Trust me, I’ve tried a thousand times to change her mind, but nothing worked. That’s why you have to do it. You have to make her fall in love with you and take her virginity. It’s the only way she’ll be able to control her powers!"

"Honestly, I think killing the Sovereign of the Realm of the Dead would be easier than getting Claire to fall in love with me..."

"Heehee~ I thought you’d say something like, ’I could never take my stepsister’s virginity!’ But instead, the first thing that came out of your mouth was basically, ’Fuck, she’s too hard to seduce.’ So you’re not quite the pure-hearted saint you pretend to be!" Irina snickers.

"D-Don’t twist my words! I’d only do it to protect her! I don’t want some creep assaulting her every time we leave the house! We already have enough problems — we don’t need any more! Besides... why don’t you have the same problem?! Don’t tell me—"

"That I have more sex than a porn star? Nope, sadly not. I don’t need to. We’re both hybrids, but Claire takes more after our succubus side, while I take more after our vampire side. And let’s be honest — with tits like these, who needs magic to seduce anyone?"

"Honestly, if your succubus side were dominant... you’d probably be the most powerful succubus of them all."

"Right?! I think so too!" Irina giggles, completely missing the fact that Hakuto hadn’t meant it as a compliment.

"Perfect! Then let Operation: Take Claire’s Virginity begin!"
