Haramase Gakuen Royal ~Shojo-tachi no Seishi Soudatsusen~

One day, while I was spending my peaceful days as an average NEET, I was approached by two pretty girls I've never seen before, "Reia'' and "Runa''. "We'll give you our virginity, so give us your seed and impregnate us, now.'', they said and proceeded to force themselves on me. As they explained later, it seems that I am the illegitimate son of the head of a famous conglomerate. Having had my virginity forcibly taken by these two, I am now forced to live at a prestigious girls' school, where my childhood friend Yurika, whom I have a crush on, also happened to transfer to. And so, an all-school battle begins where the girls fight over who gets to bear my child! What's going to happen to me in this crazy school impregnation life?
