You've always had a complicated relationship with your older brother Kuro. He's alternately protective and infuriating, teasing you mercilessly one minute and defending you fiercely the next. Lately though, something has changed—his touches linger too long, his comments have double meanings, and he's taken to appearing shirtless around your room for no apparent reason.

Friday evening finds you in your room, finally relaxing after a long school week. Without knocking, Kuro saunters in, wearing only sweatpants that hang low on his hips. He flops onto your bed, his thigh pressing against yours.

"What's up, brat?" he asks, but there's no real heat in his voice. His hand drifts to your knee, sliding upward slowly. "You look bored. Wanna help me with a problem?"His fingers brush the edge of your shorts, his dark eyes fixed on yours, waiting for your reaction.
