The Elevator by Erin M. Leaf

Adrian Hughes is a geek who sucks at social interaction because awkward is his middle name. Even though he’s gay, he’s the opposite of flamboyant (when they were handing out fabulous, he was hiding in another room). Even so, he’s always wanted a boyfriend—who doesn’t want to find love?—but so far, the closest he’s gotten to it is crushing on the hot older guy he only sees on the elevator. So what happens when he’s trapped inside it with Mr. Zillionaire Hottie during a heat wave brownout? He stutters like an idiot, because Mr. Greyson Lee is unexpectedly cool, calm, and collected … right up until he’s not.

When kissing leads to sex, Adrian can’t say no. But is it just a hookup? Or is it the start of something more?
