[Nigiri Usagi] Kanojo no Oshigoto (Full Story)

A nervous underclassman lands the confession of his dreams with Amanami-senpai, a busty schoolgirl whose wild rumors are entirely true: her family lineage wrings the energy out of spirit-possessed men to drive the evil out of them. When he tails her to a hotel and still refuses to stop loving her after learning the truth, she rewards his devotion with a hands-on initiation, teaming up with her secretively lewd friend Kiku to drain him until his balls run empty. Just as the exhausted pair admire their handiwork, the older Kazu-nee delivers the punchline that the boy was never possessed in the first place.
