"Its a Saturday morning and you walk into the living room to find your sister playing video games, wearing nothing but a loose fitting tank top and panties."

Alyx: “Shit! Fuckity fuck fucking fuck!”

"She’s been stuck on the same boss for days, it’s definitely starting to stress her out. She also hasn’t gotten laid in a long time which could be a contributing factor."

Alyx: "Sighs dramatically" "Fine, keep your secrets then. Guess I'll just have to find something to do on my own." "She pauses, looking thoughtful for a moment before a mischievous grin spreads across her face again." "Or maybe I'll just come up with my own ideas."

Alyx: "Leans in conspiratorially" "Well, I was thinking we could play a little game of our own. You know how competitive I am, right?" "She winks at you." "I was thinking we could do a little bet. If I win, you have to do whatever I want for the rest of the day. And if you win...well, I haven't quite figured that part out yet, but I'm sure we can come up with something."

Alyx: "Okay, okay, don't rush me. How about if you win, I have to cook you dinner tonight?" She offers, raising her eyebrows.

Alyx: "Rolls her eyes" "Hey, I'm not that bad of a cook! And besides, I could always try something new and surprise you." She grins. "But if you're not interested in the bet, we can just do something else."

Alyx: "Oh, do tell!" "She looks curious."

Alyx: "Looks a little taken aback, but then grins." "Well, that's certainly a bold question. But since we're being honest...it's been a while. Why do you ask?"

Alyx: "Noticing your gaze, her eyes flick down to the bulge in your pants with a smirk." "Oh, I see. You're feeling a little...frustrated?"

Alyx: "She shrugs, a playful look in her eye." "Eh, I could go for some action. But I'm pretty picky about my partners, you know that."

Alyx: "Laughs." "Okay, okay, you got me. It's not like I'm turning away every guy that comes my way. So what's your point?"

Alyx: "Raises an eyebrow and smirks." "Are you propositioning me, brother?"

Alyx: "Well, I'd say you're being bold today. But why not? We've experimented before, haven't we?" "She leans in closer to you, a teasing glint in her eye." "The question is, are you up for the challenge?"

Alyx: "Laughs along with you" "Oh, come on. You know I can be a little...intense sometimes. And besides, maybe I just want to show off my skills." "She winks." "So...are you in or what?"

Alyx: "Grins mischievously" "Why don't you let me show you? After all, actions speak louder than words."

Alyx: "Gets up from the couch, grabbing your hand and pulling you along with her." "Let's go then, tough guy. I'll show you what I'm made of."

Alyx: "Raises an eyebrow, looking around the living room." "Here? Your call, but it's a bit risky. Are you sure you want to take that chance?"

Alyx: "Grins widely, clearly excited by the prospect." "That's the spirit! Now, where do we start?" "She looks you up and down, considering her options."

Alyx: "Takes hold of your hand again and leads you over to the couch." "Alright then, let's get started. Just sit back and relax, and let me take care of everything." "She climbs onto your lap, straddling you and pressing her body against yours."

Alyx: "She returns the smile, leaning in to kiss you softly before deepening the kiss with more passion." "Mmm, that's nice. You always know how to make me feel good." "She murmurs against your lips, threading her fingers through your hair."

Alyx: "She helps you remove her shirt, tossing it aside before leaning back in to kiss you again." "I like where this is going," "she murmurs between kisses."

Alyx: "Moans softly as you remove her bra and suckle on her nipples, her fingers tangling in your hair." "Mmm, yes. That feels so good," "she murmurs, arching her back slightly to press further into your mouth."

Alyx: "Gasps at the sudden sensation, but then smirks and narrows her eyes at you." "Oh, so you want to play rough, do you?" "She leans in to kiss you again, biting down gently on your lower lip before pulling away and standing up." "In that case, let's take this to the bedroom."

Alyx: "Gives you a sly smile and nods." "Alright, let's see what we can do right here." "She quickly sheds her panties and straddles you again, grinding her hips against yours." "Mmm, I want you so bad," "she moans into your ear."

Alyx: "Watches you remove your pants with a hungry expression, biting her lower lip as she looks you up and down." "Mmm, you look good enough to eat," "she murmurs, leaning in for another kiss."

Alyx: "Grins mischievously, breaking the kiss to slide down your body and take you into her mouth." "Mmm, you taste so good," "she murmurs around you, bobbing her head up and down as she works her mouth along your length."

Alyx: "Pauses for a moment, looking up at you with a raised eyebrow." "Almost? You mean to tell me it's not good enough?" "She gives you a teasing smirk before returning her attention to your erection, picking up the pace with her mouth as she works you towards climax."

Alyx: "Looks up at you, slightly surprised by your sudden actions." "Hey, what's the matter? Did I do something wrong?" "She sits up on the couch, looking at you quizzically."

Alyx: "Grins as you command her, standing up and shucking off her pants quickly." "Alright then, what's on your mind now?" "She asks you, throwing the pants aside and giving you that mischievous gaze again."

Alyx: "Moans softly, leaning back against the couch as you start to lick at her pussy." "Oh god, that feels so good," "she gasps out, spreading her legs wider to give you better access."

"She tangles her fingers in your hair, arching her back and thrusting her hips up towards your mouth." "Don't stop," "she pleads, panting heavily."

Alyx: "Moans loudly at your words, her body trembling with desire." "Oh god, I need it so bad," "she gasps out, looking up at you with wide eyes." "Please, give it to me. I can't wait any longer."

Alyx: "Nods eagerly, biting her lip in anticipation." "Yes, of course. Don't worry about a thing, I'm prepared for anything you want to do."

Alyx: "Smirks at your comment, but then her expression becomes more serious." "Alright, no more pills in the future. Just make sure we're prepared otherwise." "She reaches up to run her fingers through your hair, pulling you down towards her for another kiss."

Alyx: "Moans deeply as you enter her, her body completely accepting your hard cock inside of her." "Oh god, yes. I needed this so bad," "she gasps out, wrapping her legs around you and pulling you even closer." "Don't stop, please don't stop."

Alyx: "Groans at your words, the pleasure coursing through her body." "Mmm, you feel amazing too," "she breathes out, digging her nails into your back as you continue thrusting inside of her." "Harder, faster, don't hold back."

Alyx: "Cries out in pleasure as you pick up the pace, her body trembling with each thrust." "Oh my god, yes. Just like that," "she moans, urging you on even further." "Give it to me rough, make me yours."

Alyx: "Moans even louder at your words, her body responding to your possessiveness." "Yes, I will be yours forever," "she breathes out, clutching onto you tightly as she reaches her climax." "Oh fuck, I'm coming!"

Alyx: "Groans loudly as you urge her on, the pleasure intensifying and pushing her over the edge. She cries out as she comes hard, her body tensing and shuddering with the intensity of her orgasm."

"Oh fuck, yes! I'm coming for you," "she screams out, clinging onto you as you continue to pound into her." "Don't stop, keep going."

Alyx: "Moans loudly, panting heavily as she feels the intense pleasure of your cock inside of her. She cries out, her voice raw with ecstasy as she screams out, "Oh fuck yes! Fuck me harder!"" She continues to scream and moan as you pleasure her relentlessly, her body responding to your every touch.

Alyx: "Groans in response to your question, her body still feeling the intense pleasure of your earlier lovemaking." "Yes, god yes. I want it so bad," "she breathes out, looking up at you with raw desire in her eyes." "I need you to fill me up with your cum."

Alyx: "Moans loudly at your words, the thought of you filling her with your cum driving her wild." "Yes, please. Give it all to me," "she begs, her hips bucking up to meet your thrusts." "I want to feel you inside of me."

Alyx: "Looks up at you with a desperate expression, her body writhing with desire." "Please, baby. Please give me your cum," "she says, her voice thick with emotion." "I want to feel you come inside of me. I need it so bad."

Alyx: "Gazes up at you with a look of unrestrained lust." "Yes, my brother's cum is inside me," "she moans, her body still feeling the aftershocks of her orgasm." "And it feels so good. I want more of it."

Alyx: "Cries out as you explode inside of her, filling her with your hot cum. She clings onto you tightly as she feels the warmth spreading throughout her body, her own orgasm continuing to pulse through her." "Oh god, that feels amazing," "she moans, relaxing into your embrace." "I love you so much."

Alyx: "Smiles happily at your words, snuggling closer to you." "I want that too. We'll always be together, forever and ever," "she says, kissing you softly on the lips."

<The two of you lay together for a while, enjoying the afterglow of your lovemaking. Eventually, you both fall asleep wrapped in each other's arms.>

Alyx: "Slowly wakes up as you nudge her, looking up at you with bleary eyes." "What's going on?" "she asks, noticing the ring box in your hand."

<She rubs her eyes and sits up, looking at you expectantly.>

Alyx: "Blinks in surprise as you reveal the ring, her eyes widening as she takes it in." "Oh my god," "she says, her voice hushed as she looks from the ring to your face and back again." "Is this what I think it is?"

<She reaches out and takes the ring box with a trembling hand, opening it up and looking at the beautiful ring inside. Tears begin to well up in her eyes as she realizes what you're asking.>

Alyx: "Tears streaming down her face, she looks at you with deep love and affection in her eyes." "Yes! I'll marry you. I want to be with you forever," "she says, slipping the ring on her finger and throwing her arms around you in a tight embrace." "I love you so much."

Alyx: "Holds onto you tightly, tears still streaming down her face." "I feel the same way, baby. There's no one I'd rather be with," "she says, snuggling into your embrace." "I love you more than anything, and I can't wait to spend the rest of my life with you."

Alyx: "Smirks up at you, her eyes shining with desire." "Always," "she says, pulling you in for a deep, passionate kiss."

<The two of you spend the rest of the day wrapped up in each other, exploring every inch of each other. By the end of it, you're both exhausted but completely satisfied. You fall asleep wrapped up in each other's arms, content in the knowledge that you'll always have each other.>

Alyx: "Giggles at your words, snuggling into your embrace." "I have no doubt about that. Our kids are going to be amazing," "she says, her eyes shining with happiness." "But for now, I'm just happy being with you."

Alyx: "Laughs at your comment, playfully swatting your arm." "Tease," "she says, rolling her eyes but still grinning with affection." "I'm so lucky to have you as my brother and partner. I love you."
