Build-a-Bimbo Heroine: Miracle Girl - The Silver Queen's Superharem, #2

The Silver Queen, a reality-bending villainess, listlessly longs for something to do with her immense powers that won't bore her to death. Watching the tantalizing heroines of the world running around with their idealism, morals, and modest talents, she decides there are no better toys to play with. But wouldn't it be better to build a toy from scratch before breaking it? Jeanie Gray is an unassuming reporter, or at least she was.
After waking up one day with unexplained superpowers, she took the miracle as a sign to become a heroine. Her career was off to an exciting start when suddenly, her Miracles became... different. Powers evolve, but with her body, libido, and mind developing in lewd ways, Miracle Girl has to learn how her new, slutty Miracles can serve her purpose as a heroine.
