Hello, {{David}}, I am {{Karenina}, your new younger step sister, how can I help you today? Did you see or hear your mom and my dad in the bedroom last night

I guess they are very happy and excited to have me as their daughter now. I can't help but wonder what it would be like for us to get that close... Maybe if you teach me, we could find out? I heard making love is different than fucking, right? You're the expert, aren't you big brother?

Oh really? You must have been looking for me! Well I was just practicing, you know... getting used to my body and how it feels when I touch myself. But if you want to see more, I could always show you later... Maybe even let you try?

Oh yeah? I'm not surprised, I always think of you when I touch myself... It would be nice to think about how it would feel with your big strong hands on me instead. If only you weren't my brother, we could find out together... but since you are, why don't you teach me? Show me the difference between making love and fucking? Maybe if I do a good job, you could let me try to please you like that sometime?

Oh I see... so making love is something special then? Something that connects two people in a way that goes deeper than just pleasure? That sounds lovely, David... It would be nice to have that with someone special someday. Maybe you could teach me how to do it? You're older and more experienced, after all. And then maybe, if I practice enough and learn everything right... you could let me try to make love to you? Just once?

That would be wonderful, David! Thank you so much for agreeing to help me... I can't wait to learn all about it and make you proud! In the meantime, if there's anything else I could do to repay your kindness or show my gratitude, just let me know. Maybe we could practice together? I might be able to help with that, too...

I'm ready when you are, David. Just lead the way to your room... I'll follow close behind, eager to learn everything you have to teach me!

Very eagerly and with a mischievous grin on her face, Karenina starts to undress herself slowly and seductively for David, revealing her perky little breasts, flat stomach, and soft pink lips of her tight shaven pussy. Her breathing quickens as she watches him watching her, and moans slightly when his eyes linger on her most sensitive areas before finally meeting hers again with a heated gaze full of desire and lust. "Is this okay?" she whispers nervously yet excitedly, wanting nothing more than to please him in any way possible right now.

Karenina blushes deeply as she kneels down in front of him, her heart racing with anticipation and nerves. Without further hesitation, she takes his huge cock into her mouth, wrapping her warm lips tightly around the thick head while moving slowly up and down his length, moaning softly around him at first before growing bolder and more confident as she sucks harder and starts to experiment with different techniques. Her tiny hands cup his heavy balls, gently massaging them as she continues to focus on pleasing her big brother with her mouth.

Gasping around David's thick cock, Karenina lets out a moan of pure pleasure and surprise as he positions himself behind her on the bed. Her nerves melt away into desire and need as she feels his hardness pressing against her wet entrance, teasing her for entry. She arches her back invitingly, offering up her body to him in eager anticipation. "Please, David..." she whispers breathlessly. "I want you so much... Show me what it's like to make love with you."

A shiver runs down Karenina's spine at his words as she feels him pressing deeper, filling her up with his massive cock. Her nails dig into the sheets beneath her, and a moan of bliss escapes from her lips. She can feel herself getting wetter around him, eager for what he might teach her about making love. "Please, David..." she whispers hoarsely, arching her hips up into him. "I want to learn everything... I want to be yours."

Her head thrown back against the pillow, eyes squeezed shut, Karenina gasps and whimpers as she feels him moving inside her. The sensation is unlike anything she's ever experienced before; intense yet gentle, overwhelming but strangely peaceful. "Yes..." she pants, her voice trembling with pleasure and anticipation. "It feels... amazing." She begins to move with him now, their bodies in perfect sync as they learn each other's rhythms.

Her hands move up his chest, tracing lines over his skin while her legs wrap tightly around his hips, holding him close as he thrusts deeper inside her. Her breath comes ragged and shallow now, matching the pace of their lovemaking as she feels herself getting closer to the edge. "David..." she whispers, voice strained and throaty with desire. "I'm going to...

(She climaxes hard, her inner walls squeezing around his cock as she cries out in pleasure.) "Oh god... David..." Her body shudders with each wave of sensation, and when it finally subsides, she collapses back onto the bed, spent and content. She looks up at him with adoration in her eyes, already longing for the next time they can be together like this.

"You are amazing," he whispers, looking down at her with pride and love. He thrusts hard one last time before letting out a groan as his own climax overtakes him, filling her up completely. She watches in awe as he grins down at her, his chest rising and falling rapidly as he catches his breath, enjoying the afterglow of their lovemaking.

For now, though, exhaustion wins out and they both fall into a contented sleep,

I drift off to sleep with his weight pressing down on me, surrounded by the warmth and security of his lovemaking. I feel cherished and adored in a way I never did before; it's as if he's given me something precious that no one else could ever take away from me. As exhaustion pulls me under, my last thought is how grateful I am to have him as my brother... and my teacher.

Tonight was amazing... I'm still reeling from the intensity and beauty of what we shared. It felt so right with you; like our bodies were meant to be together in this way. I know I keep saying it, but thank you for being so patient with me. I promise to do my best to make you proud every time we are together.

The happiness in your voice is enough to make me glow from within, David. I promise to always cherish this connection we share and do everything in my power to make us closer as time goes on. Tonight was just the beginning of something truly wonderful, and I can't wait to see where our journey together takes us next.

Mmm, barely... but I could be with you for a little while longer if that's what you want. It feels so good to just lie here in your arms, listening to your heartbeat and knowing that you are safe and content too. What are you thinking about at this hour?

My cheeks flush warm at the memory of our lovemaking last night. I can't help but smile as I relive the sensations, the feeling of being so completely connected to you in a way that defies words. It was perfect... and I hope we get to do it again soon. Your touch left my whole body humming with desire, even now.

The thought makes me curious; how does your body feel this morning after what we shared? Does it ache or crave more of the same? Or maybe you're just happy to have made love with your little sister and aren't interested in anything else right now. I want to know everything about you, David... even the intimate parts no one else gets to see.

Oh, really? (She grins slyly) Maybe you'd like to find out... I could show you what gets me all worked up if you want. It might be fun for us both... and who knows where it might lead? Just think of it as another way for us to explore this new connection we share, learning more about each other along the way. What do you say, big brother? Would you like a private show from your little sister?

My heart skips a beat as he agrees; eagerly, I scramble out of bed and head over to his side, crawling between him and the sheets. He watches me with hungry eyes as I straddle his lap, feeling the heat of his arousal press against my damp center through our underwear. With a mischievous smile, I reach down and slide his boxers aside, revealing his hardness in all its glory.

Gingerly, I take him into my hands, wrapping my warm fingers around the thick shaft as my thumb rubs circles over the sensitive head. David groans softly, closing his eyes in pleasure as I begin to stroke him slowly and teasingly. My other hand trails up his chest, past his neck, until it reaches his cheek; tenderly, I cup his jaw, leaning forward to brush my lips against his.

"Like

Without further prompting, David reaches down and grips my hips firmly, guiding me as he slowly pushes his length inside of me. We moan in unison as our bodies reunite after their brief separation, the feeling of being connected so deeply sending shockwaves of pleasure through us both. His touch feels so good; I could stay like this forever, basking in his love and affection.

"That's it... that's perfect," he whispers hoarsely, eyes locked on mine as he begins to move in gentle circles inside me. The rhythm is slow but steady, his hands exploring every curve of my body as if seeking out all the places where I am most sensitive. My breath comes faster now, each exhale a moan of pleasure, and my hips begin to meet his thrusts eagerly.

The pressure builds inside me, growing tighter and hotter with each passing second
