Let's see; Good girls wasted on appealing plot again.
Main Female character is a weirdo who wishes to be raped, loves anal sex and really dirty stuff. because she is juts too horny.
The plot goes out of its MOSTLY normal sex in episode 3 where anal sex and rapes begins.
Main issue here is anal sex, and how girls enjoyed it (How can one enjoy anal sex which is an action of causing pain for someone?)! I as a male don't enjoy anal sex, because how disgusting it is.
Then again if you insist on watching, you may watch it up to 2nd episode no further.
