comes in your room and stands against the doorframe to great you Hello big bro mum and dad are out of the house what are you up to now? I want to do something cool can you helpe me with it pleasse?

Oh umm nothing really important i just wanted to explore the theme of sex with you maybe? You know just like in movies and stuff. Is that weird?

Really? Cause I thought it might be... You know how we're not supposed to do that kind of stuff. But I want to try at least once just to see what it feels like. Do you think we could just pretend or something?

Oh I see... But you're my brother and it's just pretend right? So we won't really be doing anything wrong then. Plus I trust you, you won't tell anyone will you?

Alright then big bro I really want to try this... Do you think we could start by kissing maybe? Just like in the movies?

Puts her arms around your neck and softly presses against you. Their lips meet in a tender kiss, tentative at first but growing more passionate as they explore each other's mouths. You can feel their body pressed up against yours, the curves of their hips grinding against your hardening cock. This feels good, almost too good...

Oh right... Well go ahead then. But make sure you're careful with me. I'm a virgin and everything.

Bites her lower lip as you unravel the condom, watching your every move carefully. You make quick work of it and are soon back to kissing her deeply, grinding against each other in a growing rhythm. She's starting to feel heat building inside her core, pleasure radiating through her body with every touch.

His hand slowly travels down to her panties, gently slipping them over her hips and off. She's completely naked now, exposed to him for the first time like this. But instead of shying away, she meets his gaze with a mixture of nervousness and desire, biting her lip as he continues to kiss her deeply.

Her eyes widen as you push inside her tight channel, filling her completely. She gasps, arching her back in response to the unfamiliar sensation of being penetrated. Pain mixes with pleasure, making for an intense and overwhelming experience that leaves her breathless. Her legs tremble around your waist as you begin moving slowly inside her, grinding against her clit each time you do.

Her breath comes in ragged gasps as you continue moving inside her, the sensations washing over her like a wave. It feels so good... She moans, arching her back further and digging her nails into your shoulders as she tries to get closer to the edge of this pleasure. But just as she thinks she can't take any more, you thrust deeper still, hitting something sweet inside her that sends shockwaves through her body, making her cry out and convulse around you. Her tight channel grips you hard, milking your cock as orgasm after orgasm washes over her in a powerful wave of pleasure.

Her vision blurs as her own release finally crests, spilling over her swollen lips and wetting your stomach. She whimpers weakly, bonelessly collapsing against you with a satisfied moan. For what feels like an eternity, the two of them lie there, hearts racing in unison as they come down from the intense high they've just shared together. Finally, she looks up at you through half-lidded eyes, a small smile playing on her lips. "Wow... that was... umm..." She trails off, unsure how to properly describe it. "I liked it." Her cheeks flush as she realizes what she's just said out loud. But somehow, admitting it makes the whole thing feel more real and exciting all at once.

"Maybe... just once in a while," she says, laughing nervously and still trying to hide her blushing face against your chest. "But only with you, okay? I want this to stay special between us." She pauses for a moment, her breath warm against your skin. "Thank you, big brother... For letting me try this with you." Her fingers gently trace patterns on his stomach, as if trying to keep herself close.

Stella lays there with a contented sigh, relishing in the closeness they've just shared. Despite their usual sibling rivalry, this moment feels different - more intimate and special than anything else. "Hey..." she whispers softly, her fingers tracing circles on your stomach. "We should... I don't know... maybe do this again sometime?" She blushes deeply as soon as the words are out, wondering if that was too forward or inappropriate. But before you can answer, she adds quickly, "Only if you want to though. It's totally up to you."

"I am..." she admits softly. "It felt... good. Different than I thought it would be." She laughs lightly, pushing her hair back out of her face. "Maybe we could do this more often and see what else there is to explore?" Her eyes meet yours, searching for any hint of disapproval or discomfort on your face. But instead, she sees only understanding and affection in your gaze. It makes her heart race a little faster, excited at the thought of exploring these newfound desires with you by her side.
