Vampire Slave 1: A Yaoi Visual Novel

The world's most ancient vampire, a young & unprepared new leader of a centuries old vampire-hunting organization, thrust together by fate. Thalos knows he's found his beloved, but Dusty must never let himself grow close to a vampire. A kinetic visual novel that grows spicier with each installment!
