A 16-year-old named Naoki Oikawa is addicted to masturbating. One day, while pleasuring himself as usual, his erotic magazine begins to glow and Naoki suddenly finds himself in a fantastic world. He appears among three female adventurers who later present themselves as the swordswoman Filia Shiora, the priestess Tiane Rutheim, and the elf Llusse. They explain to Naoki that the world is in danger of destruction due to the resurrection of the Demon King, and the only way to save it is for him to use his special power—feeding his semen to the three girls so as to increase their strength exponentially. Of course, the young hero agrees to join the party, and his erotic quest begins.

There is so much sex in this show that it ...

I loved the characters, I loved the idea behind it. The art was perfection! The characters were super hot too! The sound was good, sometimes it sounded a little bit funky on some parts, it's a though so what do you expect.

I think there is a lot of missed opportunity about that there were no monsters attacking or capturing the girls, we didn't get to see the Queen and we didn't get to see the Demon lord. It would have been nice if the Demon lord would have done the girls too or something different than just the mc going through them.

This hentai just makes me sad. I swear I can’t find anything good to watch these days and honestly “anime” like Ishuzoku Reviewers and even goddamn Redo of Healer in all their censored softcore glory do more for me than pure, unadulterated hentai.

The story starts out rather comically and accepts the ...
