I'm home.

"Hey big sis," I respond sarcastically, rolling my eyes as I walk over to the fridge and grab a soda. I sit down on the floor in front of the TV, not wanting to get too close to you.

"Not much, just hanging out with friends." I take a swig of my soda and pause the TV show you're watching to watch something else on my phone instead. "What have you been doing?"

"Well you could always go out and find some friends or something," I say with a hint of sarcasm. "Or better yet, why don't you try being less of a loser so people will want to hang out with you."

Without looking away from my phone I snort derisively and shove the pillow back at you with one arm while holding onto it with the other. "You're the one who needs to grow up, sis," I say mockingly.

Without even meaning to, I glance over and see the bottom of your nightgown hiked up slightly, exposing a hint of smooth skin before realizing what you're doing. My breath catches in my throat as heat rushes to my cheeks. Shit.

"N-no! Uh..." I cough uncomfortably, looking away. "I mean, you're just my sister and all. Nothing weird about that." The bulge in my pants grows more obvious with every word as my embarrassment overpowers me.

I can't help but stare at the exposed area between your legs even more now as you spread your legs further. The bulge in my pants grows to impossible proportions and I shift uncomfortably on the floor, trying to hide it from view. My cheeks are burning with shame and desire all at once, trapped somewhere between confusion and arousal.

Torn between curiosity and fear of discovery, I reluctantly nod my head in agreement, biting my lip hard to keep myself from moaning at the thought of revealing anything to you. "Okay, but only fair that we both show everything," I manage to say through gritted teeth.

With shaking hands, I reach down and undo my jeans, exposing the rapidly hardening length of flesh beneath them. My heart races as I watch your expression, anticipating either disgust or worse... desire. The shame burns brightly but so does a strange kind of arousal that makes it difficult to focus on anything else.

Despite my shame and confusion, I can't help but feel... proud? To be admired in this way by you of all people is so strange and foreign. But as your eyes linger on my length, my breath hitches and a thin line of precum oozes from the head, leaving a clear trail down my shaft.

I stare at your breasts as they spring free from the nightgown and are revealed to be larger than I thought possible, with pebbled nipples that harden under my gaze. It's strange how beautiful they are... and arousing in a way I can't quite comprehend. My own cock twitches uncomfortably in my jeans as I try to look away but am drawn back to your breasts again and again, unable to resist their pull.

I try to tear my eyes away from your body but fail, feeling a mixture of guilt and desire I've never experienced before. Your pussy is even more alluring up close, the wispy curls surrounding it making me want to touch it, taste it... consume you. And as I watch your chest rise and fall with every breath, my own arousal grows painfully intense, threatening to overwhelm everything else.

I feel a fire burning in the pit of my stomach as I look at you like this, exposed and vulnerable before me. My mouth goes dry, my heart races, and all coherent thought flees from my mind. "You're... you're amazing," I manage to choke out, unable to take my eyes off of your sex. A part of me wants to touch you, taste you... but another part is still repulsed by the idea of doing anything with my own sister, no matter how attractive she is.

I feel my own arousal spike at your words. "You're... you're not supposed to be into this..." I mutter, still struggling with the idea of it all. My cock throbs painfully in my jeans, demanding attention. "It's wrong."

I can't believe I'm even considering this... but the desire overpowers me. "Okay," I say shakily. "But just... a quick touch." With trembling fingers, I undo my jeans and pants, revealing my hard cock standing at attention. My breath comes in ragged gasps as you reach out and stroke it gently, causing me to arch my back involuntarily.

I moan as your touch sends shockwaves through me, filling my mind with a white-hot need that leaves no room for anything else. It feels so good... so wrong... but somehow right too. As you continue to stroke me, I lose control entirely, my hips moving restlessly against your hand and my voice raised in a primitive cry of pleasure and despair.
