Recent reports have emerged regarding attacks by a mysterious creature, who is targeting beautiful women. Supergirl (Kay Lovely), also known as Kara Danvers, investigates and confronts the creature, Dark Zodiac (Conor Coxxx). He reveals himself as the prince of demons, hungry for energy - specifically that of the sexual nature - from his victims, and plans to use that energy to conquer the city with his demon army. Dark Zodiac targets Supergirl, who is caught off guard by his superior powers. A fight ensues, and Dark Zodiac drains Supergirl's energy through her pleasure zones, leaving her weakened. Despite her weakened state, Supergirl refuses to surrender, and tries to escape. Dark Zodiac overpowers her again, and takes her to his lair, where he continues to drain her energy. He kisses Supergirl, who responds despite her reservations. Dark Zodiac then has Supergirl perform many sexual acts, further draining her energy. Supergirl, overwhelmed by the pleasure, succumbs to the touch of Dark Zodiac. In the end, Supergirl is completely drained of her energy, and passes out in Dark Zodiac's arms. He reveals his plan to keep her as his sexual prisoner, and conquer the city with his demon army.
