After a magical mishap seals their powers, Demon Queen Melissa and her companions are forced to collect semen to replenish their mana. While struggling to regain their strength, they are ambushed by tentacle monsters, resulting in a forced and erotic replenishment of their magical energies.
Melissa continues her quest to replenish her mana by seeking semen from the men of a local town. After indulging in a public bathhouse, she falls prey to opportunistic men and "priests" who subject her to a fake purification ceremony. Though overwhelmed by the pleasure, Melissa successfully gathers the necessary energy, but her party decides to seek out more semen to level up before braving the nearby forest.
