My Horny Stepmom Turns Me into Her Vampire Slave-Chapter 8: Erotic fantasies gone wrong

"O-Oh, yes, Chris, right there... oh God... aaaah... faster... aaaah... lick me faster!"

Isabelle’s moans of pleasure are even louder than the night before.

Partly because Chris is slowly figuring out which spots give her the most pleasure.

But mostly because Mia is in the room next door, and Isabelle wants her to hear loud and clear what she’s missing.

Isabelle has a theory: for a vampire to fight at their best, their mind must be clear, and sex is the best way to free it from worries.

"Until you let yourself enjoy the pleasures of the flesh, you’ll never grow stronger! Come on, princess, you’ve got a stallion living under the same roof who gets hard just from you leaning on him — take advantage of it!"

But Mia has no intention of abandoning her principles for such a bizarre theory.

"Oh God, Chris... aaaah... if I’d known you could make me feel this good... I would’ve turned you into my vampire sex slave the day I adopted you... aaaah! S-Squeeze my tits — come on, hurry!"

Chris’s eyes light up at that command. 𝚏𝕣𝕖𝚎𝚠𝚎𝚋𝚗𝐨𝐯𝕖𝕝.𝕔𝐨𝕞

Damn, finally! It’s torture having those huge tits right in front of me and not being allowed to touch them!

He doesn’t need to be told twice.

He slides both hands under Isabelle’s tank top, but she grabs his wrists and stops him.

Then she guides his hands to her breasts, keeping them on top of the fabric.

"Y-You’re not worthy of touching my boobs directly yet. But... aaah... I’ll allow you to feel them through the fabric!"

Figures... it was too good to be true. Oh well, better than nothing.

He greedily closes his fingers around Isabelle’s breasts — so large that his hands can’t even hold them fully — and starts squeezing them with all his strength and impatience.

"I-It seems... aaah... your strength is starting to match that of a real vampire! Squeeze them harder! Even harder! Oh yes... aaaah!"

BAM! BAM!

Mia bangs on the wall repeatedly.

"Lower your damn voice, Isabelle — I’m trying to study!"

But Isabelle ignores her. If anything, her cries of pleasure grow even louder, as if she’s doing it on purpose just to annoy her.

But Mia isn’t actually studying.

She’s sitting on the floor with her back against the wall between the two rooms.

She almost looks like she’s eavesdropping, even though she’d never admit it.

I-I have to make sure things don’t get out of hand. Y-Yes, that’s what I’m doing! I have to be ready to step in if I hear Chris complain that she’s forcing him to do something he doesn’t want to do.

Th-That’s what a sister is supposed to do, right? Protect her brother from that pervert Isabelle! Besides, with all the noise they’re making, it’s impossible to study anyway...

She repeats it like a mantra, as if trying to convince herself that’s the reason she’s slumped on the floor with her ear pressed against the wall.

And yet she can’t get the image out of her mind of Chris’s erection pressing against his shorts when he carried her home earlier.

For that, however, she can’t find any excuse that even sounds convincing to herself.

It’s all Isabelle’s fault — she’s infecting me with her twisted perversion! Me, the respectable Princess Mia, having indecent thoughts about my own stepbrother... it’s truly shameful!

"Y-Yes, oh yes... aaah... I’m coming... I’m comi— aaaah!"

A gush of fluids bursts from Isabelle’s pussy, splashing directly onto Chris’s face.

The orgasm is so intense that his face ends up completely soaked.

Chris’s excitement is through the roof.

This time Isabelle made him stay on his knees while licking her, so he couldn’t rub his erection against the mattress like the night before.

As a result, he’s so swollen and desperate that he could climax instantly if Isabelle even brushed against him.

"I-I did what you told me, but now... what about me?"

Chris expects something like ’Now I’ll take care of you’, but Isabelle has no such intention.

"Do what any boy in the world would do — go to the bathroom and jerk off. And you’d better be thinking about me while you do."

"Ugh... O-Okay..."

There’s an obvious note of frustration and resignation in his voice.

But Isabelle was clear with him from the beginning.

He knows perfectly well that he’s only a sex slave, and that his sole purpose is to satisfy his mistress.

And like any slave, he knows that anything beyond his duties is something he’ll have to earn.

Mia gets up from the floor and lets out a long sigh of relief when Isabelle’s moans finally stop.

Phew... that torture is finally over. Now that I’ve made sure nothing too inappropriate happened, I can go to the bathroom — I’ve been holding it for ten minutes!

Chris carefully closes the bathroom door and points his erection toward the shower. Then he begins to masturbate.

He keeps his eyes closed to help himself fantasize.

But Isabelle isn’t the object of his fantasies.

Instead, he remembers Mia’s boobs pressed against his back and his fingers sinking into the soft flesh of her thighs when he carried her home.

But his fantasies don’t stop there. He starts imagining a different ending to their walk home.

"T-Thank you for carrying me home, my friend. But before we go inside, let me thank you properly."

He imagines Mia kneeling in front of him, pulling his shorts down and taking his cock between her soft lips. Her mouth moves up and down his erection while she uses both hands to stroke him.

"M-My brother, your cock is so big... so hard... I... I want you to come on my face."

"Y-Yes, Mia... I’m going to come on your face! Harder — suck it harder— "

"C-Chris... what the hell are you babbling about?!"

Mia’s voice comes from the bathroom doorway.

Chris jolts in panic.

Instinctively he turns toward her at the worst possible moment.

The semen shoots out like a bullet, landing directly on Mia’s bare toes.

"C-CHRIS..." she hisses through clenched teeth.

"L-Listen to me, Mia, it’s not what it looks like—"

But she’s like a volcano about to erupt.

"C-Chris... GET OUT OF HERE RIGHT NOW!"
