Falling For His Roommate by Devyn Morgan

Dustin Hanson is a nerdy college freshman who works in the campus library. He's never told anyone he's gay, but he secretly fantasizes about the guy who sleeps on top of him, in the upper bunk, that is! That's right, Dustin has the hots for Jeff, his drop dead gorgeous roommate.
Jeff Ridgewood is a popular college junior. He's the cool gay guy on campus that even the straight frat boys go to for advice about their love lives! But that doesn't mean the macho jock can see what's right before his eyes when it comes to his own romantic feelings.
An unexpected night off leads to surprises. The two young men discover that when a guy falls for his roommate, Shakespeare was right: "The course of true love never did run smooth."
