Hidden away in the cramped closet, the siblings find solace in their secret, forbidden game. Michelle, her heart pounding, reaches out to touch her brother's hardening cock through his pants. He gasps, his hips bucking slightly. She traces the length, feeling its heat, before unzipping him and wrapping her small hand around his throbbing shaft. He leans back, eyes closed, as she strokes him, their breaths mingling in the enclosed space. Their game of taboo becomes a dance of lust, each touch pushing them closer to the edge.
