Manga Sex - Megachu Episode 3

An adult game by Front Wing served as the inspiration for this film! As a college student, Kousuke is an ordinary, kind person who suffers from an uncontrollable nightmare in which he turns into a sexual devil on the prowl. As he sits down to play some of his favorite video games, such as Magical Girl Lape-chan, he is baffled as to why this is happening. On one occasion, a lovely goddess called Fauna comes before him, not to fulfill his desires, but to bring him to his death! The power of an evil demon seems to be residing inside Kousuke's body. Lucky for Fauna, she comes up with a creative alternative method of stopping the demon, which entails plenty of sex with her and Jordh, her sultry elder sister (and master concocter of love potions). There's a little demon on the loose named Natsuki, who has her own ambitions for Kousuke, which is unfortunate.
