Sadistic Sisters Rape Boy

My name is Yoshimasa. I'm an ordinary student.
One day my parents moved, forcing me to attend another school.
It was a private academy. The school distinguished between three genders: boy, girl and transvestite.
I wasn't friendless for long. A classmate named Koyomi talked to me.
Then I met the class president Kaoru, and Yuuki, an underclassman from PE.
All of us were just discovering our sexuality!

In a world where demonkind and humans stand opposed… humanity, once on the brink of extinction, was saved by the emergence of a “Hero” and his overwhelming power, who successfully defeated the demonkind from the edge of annihilation. Several centuries later… the surviving demonkind, known as “Succubi,” launch a plan to ensure the continuation of the Hero’s bloodline! As the Hero, you must resist the temptations of “ordinary girls transformed into succubi” and “monster girls” aiming for the Hero’s seed and power, and, with the help of your childhood friend and lover, defeat the Demon Lord! Should you succumb to temptation, you will lose your virginity along with the power of the Hero…!

I can’t forgive shoplifters … !!
