Your Sister: Sleeper Slut

Issa grins down at you, giving your cheek an indulgent pat as she grinds a little faster in your lap. "Oh, you sweet, sweet man. Is, ah!, all of your b-brain being used to power your dick?" She hisses in pleasure as her pussy writhes, her thighs tensing as she tries to draw you even deeper insider of her. "Your sister's a goddamn firework waiting to explode. I've never seen a girl more primed for a fuck, and-!" Her words catch in her throat as she climaxes again, the handmaiden groaning and shaking her head in delight before she tremblingly sighs and finishes. "-And trust me, I know what a girl who needs to be fucked looks like."

You consider that for a moment as Issa cranes her neck down to hungrily devour your mouth. You give her tongue a little flick with yours before you pull away , Issa giving a little mew of disappointment. "Well...what do you mean?"

Her lips curl into a devilish smile as she puts her hands on your chest and begins taking slow, almost unbearably long strokes up and down your shaft. "Oh my, you're so dirty...mmmmm!" She giggles, biting her lip and screwing her eyes shut as she reaches the bottom of a particularly prolonged thrust. She gives a pair of little bucks with her surprisingly powerful hips that almost make you thunderously blow your load right then and there before she grins and resumes slowly riding you.

"Weelll...", she hums teasingly as she idly plays with your candy-colored hair, "You know how the castle's been practically lousy with suitors ever since she came of age, right?"

No. "Uh, yes."

"Weelll, she was just so shy about all of it, we handmaidens decided to ask her about it. It took some wine, but she finally fessed up: They all try to impress her with their riches and that nonsense, but all she really cares about," Issa leans in, giggles as she whispers conspiratorially to you, "-is their dicks."

What. "What?"

The handmaiden lets out a peal of laughter, breaking into a moan as she wiggles in your lap. "She can't do anything about it though, the poor thing. Being a princess must be the worst. Mandated virginity? I can't imagine seeing a man I want and not just," she runs a finger down your stomach, "mmhm, taking him." She grins bawdily again, taking a moment to look up and blow herself a kiss in the reflection from the mirror over your bed. Is that what that's for?! "We found a solution though. Every time she gets a new suitor one of us goes out and seduces him. Then the next morning we come to her bed and give her all the details about his...performance."

This can't get more fucked up. You hope this can't get more fucked up. Your dick disagrees though, and you find yourself picking up the pace of your own thrusts. "None of them are as good as you are, of course," she airily admits, "but your sister still gets something out of it. She plays with herself under her covers and thinks we can't tell, silly girl. She makes the cutest little gasps when she cums. Ah!"

You make a strangled nose and Issa lets out a gasp of her own, eyes fluttering with delight as she coos down at you. "Ooooo, you got so haaard..." She stares down at you for a moment, pieces coming together behind her eyes as she humps more and more passionately into your lap. "You knooow," she drawls, suddenly coquettish as she taps a finger to her plump lip, "one morning she asked Dehlia tell her about her romp the night before, and Tits-for-Brains forgot that she had been sleeping with you that night." Issa giggles, shaking her head ruefully. "Oh, the princess was getting so excited as Dehlia went on and on about how hung you were, and how passionate you were, and how many times she came. God, I thought your sister was going to lose her whole hand up her little cunny. She was so mortified when she asked Dehlia for her partner's name and she said it was you! I thought the poor girl was going to stay locked in her bathroom for a week!"

Issa leans in for a quick kiss, her eyes not leaving yours as she gauges your rising lust. "She definitely finished in there though. I could hear her little gasps clear as day."

The only response you can muster is a helpless grunt as you put both hands on Issa's slender shoulders, taking full control of the pace of your fucking. She gives a sigh of ecstasy as she surrenders control to you, allowing you to thrust deeply into her for a moment before she leans in to whisper mischievously into your ear. "Do you remember when we took that plaster cast of your cock?"

No. "Yes." A deep, heavy heat has been building up in your groin ever since Issa began her dirty talk; there is almost nothing either of you could do now to make this last much longer.

"I had it made into a dildo and gave it to your sister as a lark. She turned so red! I knew if I told her it was of your penis she would just die. So I didn't. And she kept it."

WHAT. "What?!" The heat in your groin abruptly holds its position, as if your lizard brain senses that this is something it does not want to miss.

Issa giggles. "She takes it out and uses it every night, when she thinks we've all gone to sleep. She tries to be so quiet! But I watch her through the crack in the door. Oh, you should see her pound herself with our little gift, biting her lip shut as those fat tits try to burst out of her nightgown. And she doesn't have a clue that it's your cock she's fucking herself with every. Single. Night."

She presses her lips right next to your ear, breathing out huskily. "How does it feel? Knowing your little sister's virgin pussy is being molded in the shape of your dick?"

You've had enough. With a roar of animal lust you hook your arms under Issa's legs and roll her over onto her back, the handmaiden first cheering and then wailing in unrestrained pleasure as you wildly thrust into her gleeful pussy. She gazes hypnotized up at the reflection of your frenzied coupling, her tongue lolling out of her mouth as your throbbing balls slap into her ass with every powerful stroke. You drive yourself as deeply into her as you can rumble out a bestial growl as the dam breaks and your orgams gushes out of you, your long-coming climax so powerful that you think you might shrivel into dust and blow away.

You still know basically nothing about what is going on.

But you know for a FACT that you are going to fuck your sister.
