The closet becomes a confessional, their bodies the only penance. Michelle's hand trembles as she reaches out, tracing her brother's length through his jeans. He sucks in a breath, his hips jerking forward. Their eyes meet, filled with a mix of lust and shame, as they give in to their taboo cravings. The closet swallows their muffled moans, the scent of their arousal heavy in the air, as they explore each other's bodies with tentative, hungry touches.
