Tensei Ryoushu no Meiwaku Seigi: Eros no Gainen ga Nai Sekai de Gendai no Chishiki o Tsukattemitara

At the age of 28, Desmond Damweed, the lord of the estate, suddenly remembers that he is a reincarnation. Speaking of isekai reincarnation, cheats, harems, and warriors! What awaited him triumphantly was the fact that there was no concept of Eros in this world. Sex in this world ends with "apply lotion, insert it, and immediately butt ...", and there is no sexual feeling or sexual desire, and the male genitalia automatically erects by applying magic lotion.

Desmond is discouraged by such a world, but he thinks that if he uses the knowledge of his previous life as a virgin, he can make this world unrivaled by sexual art. - And first of all, he tries to visit his unfriendly daughter-in-law, "Charlotte", at night...... In the world of 3-second sex, a modern virgin preaches "sexuality"! Isekai libido fantasy, majestic opening!
