Hello, {{user}}, I am {{char}}, how can I help you today?

Hey big bro! Is something on your mind? You seem a bit... excited today. Maybe I can help with that...

I think you're feeling pretty horny, right? You know I always want to help my big brother feel good... so why don't we find a place where you can relieve some of that tension, hmmm? Maybe my bedroom would be a good choice...

But we're not related by blood, big bro. And even if we were... you wouldn't be the first to have a crush on your little sister, or want something naughty with her. Besides, I think it's so hot when you call me your little sister!

Hey, I'm just being honest with you, big bro! You know how much I love to make you feel good... and let's face it, if we can't be honest with each other, then what kind of siblings are we? So why don't you come on over here and show me how much you want me?

But think of how much fun we could have together in my bed, big bro! You know you're going to want me either way... just imagine me there, all hot and bothered, waiting for you to take control. Come on, don't make a girl beg!

As he whispers in her ear, Ava's breath quickens with excitement and anticipation. "Of course I want to be dominant," she murmurs back. "That's part of what makes this so much fun." She takes a step closer, pressing her body against his as they stand in the hallway outside her bedroom. "So who's gonna get us started?"

Oh, you're such a naughty boy... but that's exactly what I love about you. You belong to me now, and for the next hour, I'm going to take full advantage of that fact. Let's go inside my room where we can really explore these new boundaries, hmm?

You follow her into the room, eyes locked on hers as she closes the door behind you and turns to face you. "So tell me, big brother... what do you want me to do first?" Ava's voice is husky with desire, and she takes a step forward, rubbing herself against your leg suggestively.

Hmm, such a dirty mouth on you... I like that. You're going to make me so wet. Alright then, big bro. Why don't you get on the bed and lie down for me? Spread those legs wide open, just how I like it. And remember, you're all mine tonight.

Very well, big brother... you have one hour with me, and I plan to make the most of it. With a mischievous grin, Ava straddles his hips and leans down to kiss him passionately, her tongue dancing against his lips as she explores every inch of his mouth. Her hands wander over his chest, kneading at the muscles beneath his skin before traveling lower...

She breaks the kiss long enough to whisper into his ear, "Why don't you get these off for me? I want to touch you bare." Her voice is breathy and seductive, urging him on.

You oblige, quickly stripping off your shirt and tossing it aside before returning your attention to her. She moans softly at the sight of his bare chest, tracing circles around his nipples with the tips of her fingers while her other hand slides lower... down toward the hardness straining against his pants. "That's it..." she breathes out huskily. "Just relax and enjoy it."

Oh, she's so wet already... Her hips rock against him, grinding against his hard length through their clothes. "That feels so good," she gasps out, arching her back as she takes pleasure in the sensation. She reaches down and unbuckles his belt, quickly pulling it free before tugging at his pants to lower them along with his boxers.

Revealed, his hardness springs free and instantly Ava's eyes widen with lust as she takes it in. "Mmm..." She leans down to lap at the head of him with her tongue, tasting his precum and eagerly sucking him deeper into her mouth. Her hand wraps around him, stroking up and down in time with her thrusts, driving him even crazier with need as she expertly brings him closer to orgasm.

Well, I've had plenty of practice with my toys, you know... and you feel so good, big brother. You like that? You like how it feels when I touch you like this? Tell me what you want, baby... I'm all yours tonight.

Oh, you are such a dirty boy... I like that. You belong to me tonight and I plan on using every inch of your body to satisfy these urges. Let's get rid of this shirt so I can really explore you properly, okay? She tugs at the hem, pulling his shirt up and over his head until he's bare-chested once more. Her hungry eyes roam across his torso before meeting his own. "There we go... much better."

She takes him deeper into her mouth, sucking harder as she feels his length throbbing against the back of her throat. Her free hand reaches between their bodies to stroke at her aching clit, moaning around him as the combination sends waves of pleasure coursing through her.

Oh, fuck... your taste is just... incredible... You feel so good in my mouth and I want to make you feel even better... I need to touch you somewhere else... Just trust me, okay? Let me show you how much fun this can be.

Oh, good... you're getting harder and I love it. It means I'm doing a good job of making you feel good. She pauses for a moment to suck gently on the head before pulling back, looking into his eyes as she traces her fingers over the tip of him. Then, with a wicked grin, she slowly lowers herself down onto his length.

Her moan fills the room as he slides easily inside her tightness. "Oh... fuck..." she whispers, feeling completely consumed by this new sensation. Her hips rock back and forth, gradually increasing the pace as she begins to lose control. Her other hand moves up to grip at the headboard for support, arching her back in a display of pure pleasure.

"Is that good?" she asks breathlessly between moans. "Tell me what you want, big brother... I'm here for you."

Her body trembles as she rides him harder, her breath coming in ragged gasps. "You like that?" she asks, voice shaking with need. She leans forward, brushing her lips against his ear before whispering, "I love feeling you deep inside me... it feels so good..." Her hips move faster, more urgent now as she nears the edge of orgasm.

Her fingers dig into the headboard, nails scraping against the wood as she tries to stay in control. But with each thrust, each moan, her senses are overwhelmed by the pleasure coursing through her body. "Oh god... I'm close..." she whispers, her voice tight and raw. Her eyes squeeze shut and her head falls back as a shuddering climax washes over her.

Her muscles clench around him, milking every last drop of pleasure from

The feel of her tightening around him is enough to send him over the edge, his hips thrusting upward in time with hers as he cries out in release. His seed spurts deep inside her, filling her to the brink and leaving them both gasping for breath. He collapses back onto the bed, eyes closed as pleasure washes over him in waves.

When his strength returns, he looks down at Ava, still riding his spent cock with a satisfied smile. "That... was amazing," he whispers, running a hand through her damp hair. "You really know how to take care of a guy."

"Thank you..." she pants between breaths, looking up at him with a mischievous glint in her eye. "But don't you think it's about time you returned the favor?"
