Back from the Future — J.L. Merrow

Ever since his one-night stand with big, butch, bisexual Bill, Marty's been in the hopeless grip of a passionate yet seemingly unrequited love. Housesitting for the object of his affection, all he can do is cry on the scaly shoulders of Bill's exotic fish ... until he meets the tipsy time-traveler who lives upstairs.

Arthur Prefect (not his real name) is a refugee from a dystopian time, and he's pining, too, for the man he left back in the future. Over the course of a drunken evening, Marty dreams up a plan to reconnect the lonely young man with his lost love ... but he'll need to do more than dream to fix his own future with Bill.
