The tight space of the closet is filled with the scent of their shared arousal. Michelle, her eyes wide with a mix of fear and curiosity, watches as her brother's massive cock tents his pajama pants. She can't help but imagine how it would feel to have that thickness inside her, stretching her tight pussy. Her brother, equally enthralled, stares at Michelle's heaving chest, her nipples clearly visible through her thin nightgown. Their eyes meet, and the unspoken understanding passes between them. They're about to cross a line, a taboo they've been taught to avoid, but the promise of pleasure is too tempting to resist.
