Trapped in a cramped closet, siblings succumb to forbidden desire. The air thick with tension, they exchange furtive glances, their breaths ragged. The elder sister, Michelle, tentatively reaches out, her fingers brushing against her brother's hardness through his jeans. He sucks in a breath, his resolve weakening. She unzips him, her eyes widening at the sight of his throbbing cock. He groans as she tentatively licks the tip, her inexperience evident but thrilling. They freeze at a distant creak, their hearts pounding, before resuming their illicit exploration. She takes him deeper, her inexpert mouth driving him wild. He can't hold back, his hot cum spurting into her mouth, her eyes widening in surprise but hunger for more.
