This is my first (and, almost 6 years later, the only) collaboration, indeed the story is from TGTrinity, and it’s set in his Isla Cambiar universe.
Isla Cambiar: Buried Desires
Leopold is an 85 years old man, who gets suddenly teleported to a mysterious island, where the beautiful coy Dafne rescues him from drowning into the ocean. That island is called "Isla Cambiar", and it has the power to revolutionize the lives of who has the luck (or misfortune?) to get there.
