This Occult Part-Time Job is an Erotic Experiment!?

Disaster awaits me, a plain college student, after the sexual encounter with an occult writer! One day, college student Futami finds a mysterious man collapsed in his apartment building! The man's name is Ichijo, who lives nextdoor. After bringing the man back to his dodgy-looking room, Ichijo, in a fervor, pushes him to the ground…!? "Let's do it together?" he asks as his body temperature rises, making Futami's dick react… They introduce themselves the next day, and Ichijo explains he is an occult writer. "I tend to lose my memory during experiments…!" he says as he explains last night's experiment, and asks Futami to work for him on the spot…!?
