[LULU-429] Trapped by a Manga-Obsessed Sibling, a Busty Schoolgirl Endures Forbidden Family Lust and Uncontrollable Release

The scene opens with a sickening sense of violation, the air thick with the scent of sweat and desperation. My brother, his eyes glazed over from hours of staring at those twisted pages, had me pinned and helpless, a mere prop for his darkest fantasies. He forced me into that degrading position, my body contorted and bound, a living doll for his obsession. I could feel the cold, unyielding grip of the restraint digging into my skin as he loomed over me, his twitchy, frantic movements betraying the pent-up frenzy of an otaku who’d lost all touch with reality. Every thrust was a brutal invasion, a non-consensual rhythm that tore through any semblance of decency, his dick pounding into me with a mechanical, incestuous fury that left me gasping and broken, trapped in the in-and-out nightmare of his making.

As the assault raged on, my own body betrayed me in the most humiliating ways. Despite the terror and the pain, a twisted heat began to build deep within, fueled by the relentless friction and the degrading spectacle of it all. I’m Yuui Tenma, the big-assed JK sister he’d always leered at, and now I was reduced to a quivering mess under his control. The pressure mounted until I couldn’t hold back any longer—a violent, shuddering climax ripped through me, and I squirted helplessly, my juices mixing with the filth of the act. I came against my will, my moans a pathetic soundtrack to his depravity, as he kept pounding away, obsessed with the sight of my huge butt jiggling with every brutal thrust, a living canvas for his eromanga-inspired horrors.

It ended as brutally as it began, with him emptying himself inside me in a final, possessive act, a creampie that sealed my shame. Left alone in the aftermath, the restraints still biting into my flesh, I was nothing but a used-up toy, dripping with his seed and my own involuntary release. The solowork of cleaning up this mess felt like a cruel joke, a reminder that even in the silence, his violation echoed in every sore muscle and sticky trail. There was no escape from the memory of that twitchy otaku dick or the way my body had responded, turning a scene of pure rape into a twisted tableau of squirt and submission, forever burned into my soul as the sister who was broken by her brother’s darkest whims.
