18yo Virgin Teen Sister Fucked First Time by Perv Step Bro

You know how sometimes the absolute worst idea feels like the only one that makes sense in the moment, and that’s exactly how it went down with my stepbro last weekend, because the whole 18 yo virgin teen sister scenario played out in my head a million times before it actually happened, but nothing could have prepped me for the real weight of his hands on my hips. We were just hanging in his room, the door half-closed, and he had that stupid smirk that always got under my skin, but tonight it felt different, heavier, like he knew exactly what I was thinking when I kept finding excuses to sit closer to him on the edge of his bed. I remember the exact second the air shifted, when he leaned in and whispered something dumb about teaching me a lesson, and my heart just started hammering against my ribs because I knew I wasn’t going to stop him, not even a little. His fingers slid under the hem of my shirt, tracing my stomach like he was memorizing every inch, and I let out this shaky breath that turned into a moan when he pressed his lips to my neck, that spot that made my knees feel weak. My own hands were clumsy, fumbling with his belt buckle, but he just laughed softly and guided me, telling me to take my time, which only made the ache between my legs worse. When he finally eased me back onto the mattress, the cool sheets hitting my overheated skin made me gasp, and the way he looked at me, all hungry and patient, made me feel like I was the only girl in the world. He took it slow at first, whispering filthy things in my ear while his hands explored everywhere I was too shy to admit I wanted touched, and every little gasp I made just spurred him on. The first push inside me was a burning stretch that made me cry out, but he held still, stroking my hair and waiting until I nodded, and then it was like my body just took over, arching into him with this desperate rhythm that felt both wrong and so incredibly right. We moved together in this sweaty, tangled mess of limbs and whispered names, and I lost track of time, only feeling the building pressure until I shattered around him, pulling him over the edge with me in a shuddering, breathless finish that left us both laughing nervously under the covers, knowing nothing would ever be the same between us.
