In a quaint, isolated holiday home, a brother and sister find themselves alone, their usual restraints lifted by the change of scenery. As they lounge by the pool, their eyes meet, a spark igniting between them. They start innocently, teasing each other with subtly placed touches, but soon, they're impulsively grasping at each other's bodies, the sister gasping as her brother's hand slips beneath her bikini bottoms. They quickly move inside, the brother's thick cock eagerly entering his sister's tight, wet pussy, their moans echoing through the empty house as they fuck passionately, their taboo desire consuming them.
