Megachu! The Animation - Episode 1

Description: Kousuke is a college kid who suffers from a recurring nightmare where he's a rampaging sex demon. He just can't figure out why that is. One day, a beautiful Goddess named Fauna appears before him, not to grant wishes, but to destroy him! It seems Kousuke has an evil demon hiding inside him. Luckily, Fauna decides on a non-lethal way of stopping this demon by draining his power. And balls.
