Experimental Marine Biology

"Just friends" is all Brooke and Dylan have ever been. (Except for that one night in high school, but they don't talk about that.) Growing up, he was her protector. Her confidante. The one guy she could always trust.
Now she's a marine biologist working toward her PhD in California, and he's an underwear model in New York. Dylan's only in town for a few days, crashing on Brooke's couch and repaying the favor by acting as her date to a friend's wedding.
It was totally an accident she saw him naked.
After that, "just friends" goes out the window in favor of friends with benefits.
It's all going great...until it isn't.
Dylan's got a ticket back to New York at the end of the week, and Brooke may have accidentally broken his heart. Can they navigate these uncharted relationship waters? Or has she tanked her oldest friendship?
