Girls holding a summoning book chant an incantation in the classroom at night... and what appears is an old man incubus!? Not the handsome incubus from the smartphone game! The girls are furious. Their spirits plummet. But the old man incubus, once summoned, can't just return to the demon world without doing anything. So he uses his demonic lust and superlative technique to make the girls in front of him cum over and over! No one can stop the endless ejaculating demon world's unrivaled dick!
