In a world where humans and demi-humans coexist, Amano Taichi has by accident drank some blood of Aoe Kuon, the most popular girl in the school. Drinking her blood changed his body to have a special constitution which awakens demi-humans. In exchange for protecting Taichi from whoever would target him, the Aoe house made him cooperate with awakening Kuon... AND TO DO THAT, HE HAS TO POUR HIS SEMEN INSIDE HER! Starting with Suzuka of the oni tribe, whom the protagonist is in love with, and Seira from the dragon tribe, there are other demi-humans who join the competition to squeeze him dry...

By a strange turn of events, Amano Taichi has become the one that possesses the "magic element of awakening" that all demi-humans seek. Taichi is to use this power to awaken the demi-humans Kuon, Suzuka, and Seira to their latent abilities by having sex with them every day, but an accident puts the entire school in a coma! To solve the situation, he needs the super-rare "Universal Sacred Milk" treasure. In order to obtain this, the three mothers of the comatose girls -- Mai, Yasha, and Sarii -- Taichi will have to have sex with them, and milk them?! The days of naughty breast milking the super erotic married demi-mamas begin.

Amano Taichi, the main character with the "Awakening Essence," had sex with many demi-humans, and as a result, his power evolved. He has been chosen to marry and have children with the pinnacle of the demi-humans, "Hathor of the Divine Cows," "Astraea of the Fairy Clan," and "Aruru of the Holy Unicorns." What
