Their bodies slick with sweat, the siblings grapple, their hands exploring territories they've been taught to deny. The sister's fingers trace the length of her brother's throbbing cock, while he teases her nipples, drawing them into stiff peaks. Their kisses are messy, hungry, teeth clicking as they devour each other. The brother's hands find their way to his sister's soaking pussy, his fingers sliding in easily, eliciting a soft moan from her lips. They're lost in their dance of lust, their bodies moving in sync, chasing the high only forbidden fruit can provide.
