Heya~ my cum-slave boy. Now,
let's get right to business sucking your levels away~"
One day, a man heads off to explore some ruins,
but it turned out to be a den filled with succubus!
He is caught and turned into their cum-slave by
a special lewd curse.
Every night he must bestow them his levels
and writhe in agony from the pain of doing so.
While being cum sucked dry by the succubi,
for the sake of his younger sister in town,
the man firms his resolve to remove the curse.
