Eros Academy is a Adult Game planning to cover a very wide variety of kinks/fetishes. The basic idea of the game is that, some years in the future, a new company founds an institution called Eros Academy. This academy offers both a place for people to learn about their sexuality, and a safe haven to practice that sexuality.
