Trapped in the closet together, the siblings cling to each other for warmth, their breath misting in the cold air. Michelle, her heart pounding, reaches out to touch James' cock through his jeans, feeling it twitch at her touch. James gasps, his hands finding Michelle's breasts, squeezing them gently. They kiss, a first for both, their tongues exploring each other's mouths. Michelle's hand moves to James' belt, undoing it with trembling fingers, as James lifts her shirt, revealing her bare breasts to the cold air and his hungry mouth.
