Luna, the dutiful sailor girl, finds herself in a compromising position with her stepbrother. As they share a cramped space, his massive, untouched cock tents his pants, visible even through his loose clothing. Luna, her uniform skirt riding up to reveal her panties, can't help but feel a surge of lust. She tentatively reaches out, her small hand wrapping around his shaft. He gasps, his hips bucking forward. Luna, emboldened, pulls down his pants, revealing his virgin cock. She strokes it, feeling it grow harder in her hand before she takes the plunge, guiding it into her virgin pussy. They fuck hard and fast, their taboo encounter filled with grunts and slapping flesh, their bodies covered in a sheen of sweat.
