Nukitashi: The Animation - S01

Seiren Island is a tropical paradise for deviants: the notorious "Pervert Law" allows almost complete sexual freedom, with few taboos or boundaries. Through its suggestive attractions, the Seirantou Health Organization (SHO) draws in visitors, while offering regular medical checks and contraceptive pills so everyone can enjoy themselves without worry. But for high school student Junnosuke Tachibana, the island is far from ideal. He has just moved there with his younger sister, Asane, and he cannot stand the empty, loveless sex. Worse, his abstinence draws unwanted attention, and anyone who defies the law is punished. Junnosuke soon meets Nanase Katagiri, a notorious island seductress. To his surprise, instead of forcing herself on him, she helps him escape from the SHO. Together they find a secret group with a single goal: to destroy the SHO. Now with a way to fight the unjust rules, Junnosuke and other kindred spirits set out to crush the Pervert Law.
