Shy Virgin Stepsister's Consensual First Surrender

I never thought my life would turn into one of those steamy fantasies I secretly read about late at night, the ones that made my cheeks burn and my thighs clench under the covers. But here I am, confessing it all—my name's Lily, I'm eighteen, a shy virgin who's barely kissed a boy, and my stepbrother Jake just became the man who claimed my first time. It started innocently enough, or at least that's what I told myself when our parents got married six months ago, blending our families into this awkward new normal. Mom and her new husband decided it made sense for me and Jake to share a house while we both finished school—me in my senior year, him at twenty, cocky and confident from community college. I'd seen him around, sure, with his messy dark hair, broad shoulders from the gym, and that easy grin that made girls at school whisper. But living together? That changed everything.

It was a Thursday evening, just a week after we'd moved in. I was padding down the hallway in my oversized sleep shirt and panties, heading to the bathroom for a shower, when I pushed open the door without knocking. Stupid mistake. There he was, Jake, standing buck-naked in front of the sink, towel slung over his shoulder like he owned the place. Water droplets clung to his toned chest, trailing down to... oh God. His cock. It was right there, thick and heavy even soft, hanging between his muscular thighs, bigger than anything I'd imagined from those sneaky peeks at porn on my phone. I froze, my eyes locked on it, heat flooding my face and... lower. He turned, not startled, just raised an eyebrow with that smirk.

"Lily? You gonna stand there staring all night, or what?" His voice was low, teasing, no anger.

"I-I'm so sorry!" I stammered, my voice a squeak, but my feet wouldn't move. I couldn't stop looking—watching it twitch slightly as he shifted, already half-hard from the shower warmth maybe? It was impressive, veined and girthy, the kind that made my virgin pussy throb with forbidden curiosity. Finally, I backed out, slamming the door, heart pounding as I fled to my room. I collapsed on my bed, hand slipping between my legs, rubbing frantically through my soaked panties as I replayed the image. What the hell was wrong with me? He was my stepbrother. But that cock... it haunted me.
