Isekai Harem Monogatari - Episode 1
This isn’t my favorite Tachibana Omina title
which is FudeoroSis, but this has the same typically nice harem take as Tachibana Omina’s other titles with thirsty girls all over.
And tsundere elves.
Our protanogist can’t help but masturbate 10 times a day every day of his life, truly a hero for the ages.
Little does he know that in a separate world where semen empowers heroines to great heights, he IS actually a great hero. Once summoned to this world you can guess what happens to him afterwards.
