In the cramped, steamy kitchen, brother and sister dance around each other, butter and sugar melting into a metaphor for their own heated desires. He watches her lick the spoon, her tongue wrapping around it, and imagines it's his cock. She feels his eyes on her, her nipples hardening, pussy throbbing. They're alone, the house silent except for their ragged breaths. He steps closer, his hand brushing her thigh, making her shiver. She turns, their faces inches apart, the scent of vanilla and lust filling the air. Their lips meet, hungry, desperate, as they give in to their forbidden craving, the cake cooling forgotten.
