Prometheus grunted deeply, like a rutting bull, those odd, strange glints of purple light flickering along the underside of his wings as his pleasure started to hit its peak. He curled the tip of his tongue around Hades's balls, nudging and gently pressing against them as he started to taste precum against the flat of his tongue.
