Michelle's soft fingers trace her brother's cock through his clothes, her heart pounding with taboo excitement. 'I can't help it,' she admits, her voice barely above a whisper. 'I want you.' Her brother, his body betraying his resolve, grows hard against her touch. 'We shouldn't,' he breathes, but his hands find her ass, squeezing gently, pulling her closer. Their lips meet in a heated, hungry kiss, their bodies grinding together, their clothes a thin barrier against their growing need.
