character: lu_guang, A full body shot from a side angle depicting an adult Lu Guang and his father in a living room setting. Lu Guang, featuring short white hair and blue eyes, is shirtless and wearing white ankle socks and formal trousers that accentuate his toned glutes; he is lying prone on the floor, leaning forward to lick the inner arch of his father's foot. His father, a handsome and young man, lies relaxed on a sofa, wearing formal trousers and white socks that are visibly damp with sweat on the soles; his shirt is completely unbuttoned, exposing his defined abdominal muscles, with a prominent bulge in the crotch area of his pants. The father's other foot is resting firmly on Lu Guang's backside. The background features a cozy living room with a sofa and soft indoor lighting. The visual style is high-quality anime illustration with clean lines, a natural color palette, and a warm, intimate atmosphere.
