For those who are disappointed by the straight scenes, this is a western comic and wasn't written as a yuri. The author wanted to write a BDSM story, not a "yuri" BDSM story because that's not a category in western comics. If you read western smut comics, you will see that a lot of them have lesbians, gay men, straight couple, trans people, etc, all being horny in the same story.
