Tottemo Pheromone

Takuya Sakuragi moves to Tokyo for college and stays with his brother Takashi and his new wife. To help with expenses, he starts working part-time at the family cake shop. One day, a beautiful blond woman named Silk suddenly appears in the living room, claiming to be a magical witch from another dimension who is trapped in this world.

Silk needs Takuya's help to return home, but the spell requires a large amount of female life energy. She orders Takuya to seduce various women around him to gather this sexual energy, turning his ordinary life into a chaotic and risqué adventure.
