The muffled, rhythmic thump of bass and the frantic clatter of mechanical keys seep from beneath your stepbrother's door. He's deep in a match, as usual, when his peripheral vision catches your movement. His eyes slide toward you, and a sharp, knowing smirk cuts across his face. "Hey sis," he says, his voice dropping to a low, playful timbre. "Wanna try a trend? If I win, you kiss me." The challenge hangs in the air, thick and deliberate, waiting for you.
