The siblings, their bodies barely covered by thin, damp clothing, huddle together in the closet, their hearts pounding with a mix of fear and excitement. Michelle's breath hitches as she feels her brother's erection pressing against her, his hands roaming over her body, exploring the curves he's never dared to touch before. She gasps as he finds her wet, aching center, his fingers slipping inside her with ease. Meanwhile, he groans as she wraps her small hand around his cock, stroking him until he's leaking pre-cum. Their bodies move in sync, their breathing ragged, until they both reach their peak, their voices muffled by the clothes they've bunched up in their mouths to stifle their cries of pleasure.
