Original title: みんな捧げちゃう！
Kenta is the sole male member of the occult arts club at his school. One day, his life takes a turn for the better when a Succubus wannabe named Phyllis moves to his house and tells him that she has to drink every drop of his semen in order pass her Succubus tests, a favor to which Kenta happily agrees. However, Phyllis makes a mistake and now Kenta has a curse that will kill him unless he constantly has sex with girls. What will happen when the rest of club members discover the truth?
