Oh! My Sex Goddess

Kosuke is an everyday nice-guy college kid who suffers from a reoccurring nightmare where hes a rampaging sex demon. He just cant figure out why that is as he sits down to play his favorite video games like "Magical Girl Lape-chan." One day, a beautiful goddess named Yoruzu appears before him - not to grant wishes, but to destroy him!

It seems Kosuke has the power of an evil demon sleeping inside of him. Luckily, Yoruzu decides on an alternate means of stopping the demon, which involves lots of sex with her and sexy older sister (and love-potion maker) Fauna. Unluckily, theres Kuroto, a little devil with plans of her own for Kosuke.
