Dispel Succubus

One day, a powerful magic was quietly cast over the area where the protagonist lives. That magic, known as the "Succubus Seed," slowly corrupts any woman it afflicts, gradually turning her into a succubus. Amidst this crisis, the spirit tribe forcibly hands the protagonist a magic that can dispel the succubus transformation, and he resolves to try to save those who have fallen under the spell. However, he must endure the relentless teasing and torment of the succubus-corrupted girls while working to undo their transformation. If he loses the struggle and ejaculates, his physical strength is drained, and in turn the girls' corruption deepens even further... Can the protagonist manage to save the girls, or will he...?​
