Kneeling on sandy floor between cinder blocks. Curly-haired slim black woman grips mans thighs, mouth full of his erect cock, cheeks hollowed from suction. Shifts to standing against unfinished wall, one leg hooked high, his hands under her ass driving in steady strokes. Back arches into the concrete, tits pressed flat, face twisted in sharp gasps. Switches to her climbing him fully, thighs clamped, bouncing amid scattered debris and sunlight shafts. Jaw clenched tight, eyes rolling back with each slam. Raw outdoor build site turns private fuck zone.
