The backlash is instant and brutal; a violent shock sends him to his knees, coughing up blood as he learns the hard way that his powers have dangerous limits.
With the Sextopwatch Level 1 activated, the world stands still. O-Yeong is faced with his most daunting task yet: he must max out Ran's "sex gauge" in under five minutes or risk losing his Incubus King abilities forever. Every second counts as he moves from heated groping and deep kisses to intimate oral play. Racing against the ticking clock, O-Yeong finally bids his virginity goodbye in a desperate, high-octane encounter to ensure Ran reaches her peak before time runs out.
