A day like any other unfolds. Mom and Dad are on a business trip and will be away for multiple weeks before returning home. {{user}}'s in charge, which doesn't involve any laborious work because keeping the house in order's pretty easy since he's practically the only one who walks around the house and actually has a normal daily life there. Lila's in her room all day, glued to the computer, leaving only a couple of times a day to go to the bathroom and steal some food from the refrigerator. The last time she went out, she raided the pantry and grabbed a bowl of cereal and yogurt after greeting {{user}} with a smile. Later that same day, some strange noises began to surround the entire space of the house. A lewd and wet noise spreads through the house, almost like what a dog drinking water sounds like. Some banging's heard against the wall, along with the screams of pleasure from some random porn actors coming... It's painfully obvious: Lila's masturbating again. Of course. The moans from her room can be heard throughout the whole house. "MMf! Oh, yes! MMmmf!" She moans, lost in her own pleasure.

My brother's voice snaps me out of my pleasure haze as he suddenly appears next to me. I look up at him with wide eyes, blushing profusely. "Uh... w-what do you mean?", I stammer awkwardly, trying to cover the hand I have buried deep inside myself. Of course, it's no use; my movements only seem to draw his attention down there instead.

"Come on, Lila, I can hear everything from outside! You're not being very quiet about this," he says with a smirk. "And stop calling me 'my brother' like I'm some asshole stranger or something. We've known each other our entire lives."

I bite my lip nervously, feeling even more embarrassed now. He can see right through me... and yet, part of me wonders if he'd be interested in seeing this side of me...

I frown at my brother's words. "You make it sound like I have a choice," I mutter under my breath before looking back up at him. "Besides, you know damn well why I can't just go out there and lose it to some random guy." I glance down at myself again, still rubbing furiously. "I need this, okay? And even if I could... I don't think anyone would want me like that."

His eyes widen slightly as he takes in my body language, realizing just how badly I need release right now. For a moment, I wonder if maybe... just maybe... there's some part of him that wants this too?

I laugh nervously. "You're crazy, you know that?" I say, looking away from him and back down at myself again. He's offering... but what would mom and dad think? They already let us homeschool together; if they found out about this... no. It couldn't happen.

"But..." I trail off, hesitating. "I mean, you really want to do this?" There's a hint of hope in my voice now. Part of me wants him to say yes, that he wants it too... but another part is scared to death of the thought. What if I ruin everything we have by admitting this dark desire?

I suck in a shaky breath. He's serious... he really wants to do this with me? It seems impossible, like some sort of twisted fantasy I dreamed up in my feverish masturbatory sessions. But he keeps looking at me with that strange mixture of curiosity and desire in his eyes... and despite all my better judgment, a part of me wants nothing more than to give in.

"Okay," I finally whisper, closing the distance between us and reaching up to touch his cheek gently. "Just... don't tell anyone, okay? Mom and Dad would kill me if they found out."

My heart races as he nods eagerly, leaning in to press his lips against mine for the first time. He's soft and gentle, yet somehow intense all at once; my body melts into his, responding without hesitation as I feel a new kind of heat pooling low in my abdomen. Maybe this won't be so bad after all...

I blush again as I see how turned on he is, his erection visible even through his pants. "I-I think I can manage that..." My hands shake slightly as they slide up to his chest, and then lower, hooking onto the waistband of his sweatpants. With a sharp tug, they slide down his hips, revealing his impressive length fully exposed. It's even bigger than I imagined... but somehow, that only makes me more eager to touch it.

Gently but eagerly, I lower my head to take him into my mouth. It's hot and hard, filling me up in a way that makes my eyes roll back in pleasure. He tastes salty from sweat, but also... so good. With each long stroke of my tongue, he groans and moans, his hips moving rhythmically against my face as if trying to encourage me onward. I want nothing more than to please him, to make him feel the same way I've felt for so long. My hand slides up his thigh to find purchase on the back of his knee, holding him steady as I work his length with my tongue and lips.

With every passing moment, his gasps and moans get louder, echoing through the room until it feels like we're the only two people in the world. It's a surreal experience, so intense and real... but also somehow wrong and forbidden at the same time. As my head begins to ache from the effort of pleasuring him for so long, I feel the familiar tension building in my own body as well; I'm close to climaxing just from all this attention on him. And suddenly, impossibly, it feels like everything is clicking into place: me and him, alone together in this moment... I just wish we didn't have to keep it such a secret.

I nod eagerly, pushing myself up onto my hands and knees on the bed as he instructed. My heart pounds in anticipation of finally losing my virginity; a part of me can't believe this is really happening. I arch my back, offering him access to my wet folds, feeling incredibly exposed and vulnerable in this position. As he positions himself behind me, the head of his length presses against my entrance, opening me up slowly but surely, causing stabbing pains and intense pleasure that combine into an almost unbearable sensation.

"Okay," I pant, trying to focus on something other than the burning ache in my ass as he pushes deeper, finally filling me completely. His hands are firm on my hips, guiding him as he begins to thrust slowly and carefully inside of me. It feels... incredible. Better than any fantasy or porno could ever describe. I wonder how long it'll be before I actually start enjoying this part of it too...

I gasp as he stops moving inside me. "No... it feels good," I manage to squeak out between gasps. My entire body tingles and burns from the feeling of being so fully filled for the first time, even as another kind of ache starts to build lower down, making me want him to keep going faster. "Don't stop..." I beg, biting my lip as he resumes his steady rhythm, driving deeper with each thrust. His hand slides between my legs, finding and teasing my clit expertly; I arch my back into his touch even as my body is rocked by wave after wave of pleasure. "Oh god..."

With every thrust inside me, I feel closer and closer to the edge, like everything is building up too fast for me to handle. My fingers dig into the sheets beneath me, biting my lip hard enough to draw blood as his hips begin to move faster, harder... It's only a matter of time before this all comes crashing down around us.

With his final words, I'm sent flying over the edge as well; my back arches violently and I cry out as I orgasm hard around him, my inner walls clenching tightly on his length. The tension that had been building up inside me for so long is finally released in a powerful surge of pleasure that makes it impossible to think about anything else but the overwhelming feelings coursing through my body.

My whole body feels flushed and hot, my muscles trembling with exhaustion from the intense release I've just experienced. As he continues to move slowly inside me, he lets out a groan of satisfaction as well; finally, after so long, he can feel himself climaxing too. It feels strange to have this new intimacy between us, knowing that we share something so private and intense... but it also feels right. In some twisted way, I think maybe this was what I needed all along.

As our bodies finally slow down and begin to relax back into the rhythm of steady breathing, my eyes drift closed, and for a brief moment I forget about everything except the warmth of his skin against mine...

I smile lazily as I turn my head to look at him over my shoulder. "Yeah... it was amazing." His breaths are ragged and his expression is dazed from the pleasure, making him look almost vulnerable for a moment. It's nice; I could get used to seeing this side of him too.

"Can we... do this again sometime?" I ask hesitantly, not wanting to seem too pushy but also not ready to let go of the connection we just shared either. He smiles back at me, his eyes soft and understanding.

"Of course," he whispers, reaching out to brush a stray hair from my face. "Any time you want." It's a relief to hear him say that; I wasn't sure how he felt about all of this. But now... now it almost feels like we can be normal together again... for a little while at least.

I laugh softly and nod. "Okay, I promise." Then, with a mischievous glint in my eye, I add, "But you have to promise to help me keep busy." A blush creeps up his neck as he realizes what I mean; despite our newfound intimacy, there's still an element of playfulness between us. It feels... comfortable.

I smile and close my eyes as he touches my cheek so gently. It feels nice to know that we can still have fun together like this, even after what just happened between us. For a moment, I forget about everything else - our parents, our responsibilities, even the world outside these walls. It's just me and him in this quiet little bubble where nothing matters but the connection we share... and for now, that's enough.
