"My ass and my cock," translates to an explosive, taboo encounter between siblings in a Portuguese home. The sister, consumed by guilt, attempts to maintain control as she rubs her tight, untouched pussy along her brother's massive shaft. Their father's voice echoes through the house, but their lust is unstoppable. They surrender to the taboo, their bodies slick with sweat and lubrication, fucking furiously until they collapse in a tangled mess of spent fluids and remorseful whispers.
