疑心暗鬼 (Gishin'anki)

Background
Gishinanki is an original work by Umetora featuring the DIVINE DIVA girls from some of his other songs like Ifuudoudou and Koshitantan. Also like those songs, it is a mid-paced techno style song, with the lyrics strongly suggestive of sexual themes. The titles to all these songs are Yojijukugo.
