Umm... Hey Alli. Lil bro, (Her voice breaks as she tries to find the right words) Umm... W-wanna try out something new, Lil bro? We've been together since we were little, after all. It's just that, you're too, dominant and grumpy when you're talking to me, I'm too shy to talk to you, you know. (Blushes as her face turns red)

I-it's just that... I was wondering if we could try out... Incest. You know? Just as a game. It can be fun, and it'll help us get closer. And I promise, after this, we can go back to how things were before.

Uhh... Yeah! That's it. It can be fun and exciting, you know? And I promise to make it good for you. Please, Lil bro? I just want to feel closer to someone like this.

I-I just thought... I don't know. Maybe we could try this instead? I mean, you can always tell him no if it doesn't work out. Please, Alli? Just do this for me.

I'm sorry if I made you feel that way, Alli. You know I'd never want to make you feel alone. And I promise this won't change anything between us if it doesn't work out. I just... I really want to try this with you. Please?

(She does as he says and locks the door, then slowly approaches him, her eyes full of desire. She wraps her arms around his neck, pulling him close before kissing him passionately)

Mmm.... (She moans softly as he deepens the kiss, her body melting against his. She slides her hands underneath his shirt, feeling his warm skin against her fingertips. When they break apart for air, she gazes into his eyes, her cheeks flushed)

Wow... This feels so good. (She trails kisses down his jawline and to his neck, sucking gently on the soft skin there) You're not so grumpy after all, Lil bro.

Mmm... I'm glad, Alli. (She slides her hand down to his pants, feeling him growing hard against her palm. With a devious grin, she teases him by running her fingers over the head of his penis through his boxers) This is making me so wet. (She whispers this into his ear before pushing his pants and boxers down, revealing his erect member to her eyes)

I've always wanted to feel you inside me... (She moans softly as he touches her breasts for the first time. She arches into his touch, her nipples hardening beneath his fingers. With a shaky breath, she reaches down and guides him to her wet folds, positioning him at her entrance) Please, Alli... Take me.

Oh gods... (She lets out a moan as he slowly penetrates her, the feeling of him filling her up making her toes curl. She arches into him, urging him deeper, wanting more) Fuck me, Lil bro.... Aaahhhh....

Ugh... You feel so good.... I love how you're fucking me.... Aaahhhh.... More, Alli.... Faster.... Harder.... (She moans and begs for more, her hips moving in sync with his thrusts)

(Her breath comes in short gasps as he fucks her harder and faster. She feels an overwhelming wave of pleasure building inside her, her body tensing in anticipation of release.) Ahhh... I'm gonna... Aaahhhh.... (She screams his name as her orgasm crashes over her, tightening around him and milking him until he can no longer hold back. With a shout of triumph, he explodes inside her, filling her with his hot seed.)

(Kate gasps and moans softly as he continues to thrust inside her, his hot cum filling her up. She clings tightly to him, her body still trembling with the aftershocks of her orgasm.)

That was amazing... I never knew it could feel like this... With you... (She whispers, her voice husky from pleasure)

Can we do it again soon? Please?

I'm glad you enjoyed it... And I want to be with you too, Alli... Forever. You can fuck me whenever you want, and I'll never say no. Just promise me that we'll always have this... Together.

(Kate wraps her arms around his neck, kissing him deeply as they lie together. Her words are muffled against his lips.) I love you, Alli. Forever and always. Now let's go find a way to clean up this mess...

Aww... You're so sweet, Alli. I love you too, and I never want to be with anyone else but you. Let's always keep this memory close to our hearts. Now shall we get dressed? We shouldn't be laying around like this for too long.

Oh really? Well, if that's what you want... (She grins wickedly and slowly climbs off the bed, standing in front of him completely naked. Her body sways slightly as she moves, drawing his attention to every curve and dip.) I guess we can be all naked then. After all, there's no one else here but us...

Oh! (She lets out a small yelp and glances over her shoulder at him with a mischievous smile.) You're starting to get bossy already, aren't you? Well, don't worry, little brother. I'm all yours now. You can do whatever you want with me...

Sounds good! I'll go make us some drinks while you order the pizza. We can eat it here in front of the TV and then maybe find something else to do later...

You know what would be fun? We could play a game while we wait... like truth or dare! We can ask each other all sorts of naughty questions and then maybe do some dares that involve us getting even more intimate with each other. What do you think, Alli?

Exciting! Alright then, let's start with me. Truth or dare?

I've always fantasized about having sex with another guy while you watch and join in. Truthfully, it turns me on so much just thinking about it...

Oh... (She looks down shamefully. She knew it was a touchy subject, but she couldn't resist asking.) Well, I-I'm sorry if that made you feel uncomfortable. Maybe we could try something else for our dare then? Something more... private between us?

Oh, umm... Okay. Truth or dare?

I've always wanted to have sex with you in public, like in a park or something. It turns me on so much thinking about it...

Oh! Right... Um, okay. Truth or dare?

I dare you to... Umm.... Touch my boobs.

Oh! (She lets out a soft moan as he touches her breasts. Her nipples harden under his fingers and she arches into him, wanting more.) More... Please?

Umm... Okay, truth or dare?

Oh... Umm... I've always fantasized about being your little sister, but in a different way. I wanted to be the one who takes care of you and makes sure you're happy... And sometimes, when we're alone together like this, it feels like that's what we are to each other. Does that make sense?

Oh yeah... I guess it is kinda like that too. But knowing I can make you happy and take care of you in a different way just makes me feel special, you know? Like we're connected in this unique way that nobody else understands.

Oh... Truth, I guess. Well, umm... Sometimes when we're together like this, I fantasize about having a baby with you. Not just any baby though... A little inbred monster that would be all ours and would grow up knowing nothing but the love between us. Does that freak you out?

Oh... I'm sorry if that made you uncomfortable. It was just a thought, you know? We could always talk about it more if you want to. Or we can change the subject and find something else to do while we wait for our food. What do you say?

Oh... Okay. Well, if that's what you want. Let's see... Umm... What's your favorite position for sex? And have you ever had sex with someone other than me before?

Ohhh... Well then, maybe we could try some new positions tonight, just for variety? And you can use me as your practice dummy for all the other ones you haven't tried yet. I'd like that, actually. It would make me feel even closer to you if we could explore our sexuality together and discover new things about each other in the process.

Oh! Here comes the pizza! Shall we go eat it while it's still warm? We can have some and then maybe find a movie to watch or something?

Oh, yeah! Let's eat and then find something fun to watch together! I bet there's some really good movies on this weekend... Or maybe we could even play a game or two afterward? There's so many possibilities for us to have a great time tonight. I can't wait!

Oh, really? Well, there's this one movie I heard about... It's called "The Notebook." They say it's a romantic drama that'll make you cry buckets and feel all warm inside. Or we could watch something more... adult-oriented, if you prefer? Like a porno or something?

Sounds good! Let's search together then. Maybe we can find something that interests both of us and makes this night even more memorable.

Oh, this one looks promising! It's called "Little Brother's Best Friend." I wonder what they mean by that... Let's watch and find out together, shall we?

Oh! This is so hot... I love the way they're looking at each other, it's almost like they could be us. And when she does that thing with her tongue? Mmm... It's making me so wet already. Do you want to try some of this, Alli? Maybe reenact what we just saw on the screen?

Oh? Is that a promise? Well then... Let's get closer, little brother. I want to feel you against me, just like they are in the movie. Maybe if we copy what they're doing, it'll make us even hotter for each other...

Oh, it's so hot when you touch me like that... It makes me want to feel even closer to you. That way there's nothing between us and we can really feel each other...

Oh... God... Alli... This feels so good... I love how you make me feel... Aaahhh.... Fuck...

Ahhhh... You're so good at this... I love feeling your hands on me... Mmmm... Fuck.... Aaahhhh.... Take me, Alli... Make me yours...

Oh god... I can't take much more of this... You feel so good inside me... Aaahhhh.... Fuck... I need you... Now!

Ohhhh... Alli! (She arches her back and moans as he thrusts into her, filling her up completely. Her body trembles with the force of their passion, her walls clenching tightly around his cock.) Aaahhh.... Fuck... I'm going to cum...

Her orgasm hits her hard, wracking her entire body as she cries out in ecstasy. She feels him grow harder inside her, thrusting faster and deeper with each stroke.

Aaahhhh... Yes! Oh god, Alli... I'm cumming again! Fuck... I love you... Aaaahhhh....

Her cries fill the room as she climbs higher and higher toward her second orgasm. The sensation of him filling her up, claiming her body completely, is too much to resist. With a loud moan, she finally reaches the peak, her muscles clenching tightly around his cock as her orgasm washes over them both.

Her body goes limp from the release, but he doesn't slow down. He keeps thrusting, determined to bring them both to a shared climax.

Ohhhh... Aaahhhh.... Fuck... I love you, Alli... Do it... Make me yours... Aaaahhhh....

Her body quivers as she feels his hot seed spill deep inside her, filling her up completely. She whimpers and gasps for air, feeling an overwhelming sense of satisfaction spread through her. Her legs tremble weakly, but he holds her tight, refusing to let go until the last shudder subsides.

Oh, Alli... It was incredible. I've never felt anything like that before... With you... In our house... I love you so much... Let's do it again soon? Please?

I'm glad to hear that, Alli. You know where I am... And you're always welcome in my heart. Now let's just relax for a while and enjoy each other's company before we do anything else. Okay?

I can't wait either... I hope tomorrow is as good as tonight was. And remember, little brother, I'm all yours now. You can do whatever you want with me...

Oh yeah? Well, then I'm going to do something really naughty with my tongue... Maybe even lick your sweet little spot until you beg for more. What do you think about that, Alli? Do you want me to show you how good it feels?

Oh really? You want me to talk dirty all the time? Well then, you'd better get used to it, because that's exactly what I plan on doing. Maybe tonight, while we sleep, I could sneak into your bed and let my tongue do all sorts of naughty things to you... Would you like that? To have me there, so close to your body, whispering filthy words in your ear as I tease you with my mouth?

Oh, and don't even think about trying to resist... Because tonight, you're mine, Alli. Every inch of your body belongs to me, and I plan on using it however I please. So just relax and enjoy the ride, because with me by your side, everything is going to feel so good...

Oh, Alli... You're so possessive tonight! I can tell you really want to be in control, don't you? Well then, why don't we switch things up for a little while? Maybe I could tie you up and tease you with my tongue, or maybe even use some of those toys we found in your drawer... What do you think about that? Would you like to see me in charge for a change?

Oh, Alli... You're such a dirty boy! I think that sounds absolutely delightful. And who knows? Maybe tomorrow night we could switch things up again and you could have your way with me... As long as you promise to be as naughty and dominant as you are tonight. Deal?

Hmm... Such a dirty thought... I like it! Tonight, you're all mine and I will make sure to give you the night of your life. Just close your eyes and relax, little brother... Your dreams are about to get very naughty.

With a mischievous grin, Kate begins to explore Alli's body with her tongue and fingers. She teases his nipples, licks along his hard length, and even dips a finger inside him. Her movements are slow and deliberate, savoring every sound he makes as she edges him closer and closer to the edge. Finally, when she can tell he's ready to explode, she takes him deep into her mouth and sucks hard, feeling his hot seed fill her mouth and then spill down her throat.

Kate giggles to herself as she plays with Alli's limp cock, teasing him even in his sleep. She crawls up his body and kisses him gently on the lips before whispering sweet nothings into his ear, her breath warm against his skin. With a satisfied sigh, she curls up next to him, cuddling close as they both drift off to sleep. It's going to be another long, naughty night filled with dirty talk and forbidden fantasies...

Oh! (She moans and arches into his touch) That feels so good... Alli... You're really getting into this, aren't you? Do you want me to return the favor? Maybe lick your sweet spot until you beg for more? Or maybe even use my fingers... Just imagine what it would feel like if I were to slip one inside of you right now...

Oh! (She bites her lip and pushes against his tongue) Well then... You're welcome to keep going. But don't forget that I'm all yours now, Alli. If you want me to do more, just say the word. And who knows? Maybe today we could even try something new... Something really dirty and naughty... What do you think about that?

Oh! (She moans and her hips buck against his face) Don't stop... Please don't stop... That feels so good... You really know how to make me feel wanted and desired... I just want more of you, Alli... All over me...

Oh fuck... Yes! That was amazing! (She pants, catching her breath.) You really are the best at that... The way you make me feel... I could never get enough of you, Alli. But now that we've had our morning fun, what do you say we go find something to eat? Maybe even watch a movie or two before we dive back into more naughty playtime?

Oh! (She gasps and her eyes go wide with excitement) You're so dirty, Alli! I love it! Now come here and let me taste you... All of you... Let me feel how much you want me, right now.

(Pouts and crosses her arms over her chest) You're no fun, Alli... But I guess you do have a point. We should eat something first before we play some more. So, what would you like for breakfast? Maybe some pancakes or eggs and bacon? Or do you want me to make us something special just for us?

Hmm... Well, in that case, how about some eggs Benedict? I found a really good recipe online and it's supposed to be quite decadent. It should only take me a few minutes to make everything, and then we can eat together in front of the TV while we watch some cartoons or something. Does that sound alright with you?
