Desk Birching Leaves Bare Ass Brutally Bruised

Bent over wooden desk, bare ass centered in frame, skin mottled with overlapping red welts and dark bruises radiating from center. Skirt bunched at waist exposes full cheeks, thighs tensed holding position. Male in gray shirt positions directly behind, one hand lifting fabric higher for clear view. Room setup: filing cabinet, wooden chair, wall clock ticking. Face hidden in hands, shoulders hunched against sting. Earlier frame shows hand raised mid-swing, impact fresh on pale flesh. Progression builds layers of color from pink slaps to swollen contusions. Legs shift slightly, weight on toes. No sound visible but posture screams burn.
