Mako-chan Kaihatsu Nikki 2

Mako’s pulse still races after her confession, leaving her restless and desperate for release. Alone in her room, she surrenders to her desires—until her older brother enters unexpectedly, his knowing gaze burning through her guilty pleasure. “I know what you’ve been doing,” he murmurs, closing the distance between them. Their forbidden tension ignites into something deeper, his whispered accusations melting into heated touches as their intimacy blurs the lines of sibling restraint.
