This is an HMV with Pretty X Cation 2. It starts off with what people on the outside for these two lovely ladies, and then later gets into what they do behind closed doors. This is my favorite song from Tanuki as of now, it’s a banger!
Note this is a Hentai Music Video (includes genitals), hence labeled as R18.
The jacket art for this song in DDR A20 Plus got my attention for the small details that are included in the two-faced girl. The right side is what other people see in public, but the left side is what she is in the bedroom: a kinky BDSM girl with a leather choker and a dominatrix mask. This HMV tried following that approach of public vs. private.
