The stuffy closet, their secret sanctuary, becomes a furnace as the siblings press together, barely clothed. Michelle, her skin flushed, guides her brother's hand between her legs, her panties soaked. He groans, fingers her slit, feeling her heat. They rock, their bodies slick with sweat, until Michelle, overcome with lust, whispers, "Fuck me." But a stern voice echoes outside, "I know you're in there!" They freeze, hearts pounding, as their father's footsteps approach, their taboo tryst left hanging in the stifling air.
