This is definitely worth to try for the plot! It is not directly tagged with psychological but I think this hentai lowkey mentioned some deep aspects from human beings. The feeling of getting replaced by a loved one must hurt, the feeling or guilt to impregnate someone that is not your star-crossed lover, the feeling of seeing your loved ones being in love with the one you prepared to be together for the rest of your life. Yes, it might not be that serious of a topic to talk about, but when I witness every of their sex scenes, small details of their expressions andbackground throws us a hint of their insecurity.

Theoretically, this might not be the best animated hentai you'll watch, rather I'd say I have never seen a dick that looked as pale as a ghost, there were barely any color or veins. Though, I would say out of all hentai's that existed today, won't have the realisticity and a story that actually makes sense like this gem right here. I encourage you to give it a shot, to the ones that DO give a damn about hentai WITH plot.
