Joshi Gentei♪ Haramase Harem Gakuentoshi ~Gakuen mo Machi mo Mesu mo Subete wa Goshujin-sama no Tame ni! Yokubou no mama Niku Onaho Jusei o Otanoshimi Kudasai♪~

In a world of impotent men your erect cock grants you access to the school of your choice.
You choose Joshi Gakuentoshi, an all-female campus where boys traditionally aren't allowed. The girls aren't particularly happy at first but that won't stop your libido!
Teach these athletic, intelligent, beautiful and privileged high society girls a punch-drunk pleasure! Enjoy as these elite girls drown in a sea of carnal pleasure!
Teach them the path of ERO and have them worship you as their God!

Transform this once all-girls college town into whatever erotic fantasy you can think of! School uniforms, PE uniforms, school swimsuits, change them all to erotic clothing!
Fuck them silly during class to teach the girls who's boss!
This entire town is one giant onahole available for your sexual gratification!
