Wrong Bed, Right Brother

I've been crushing on my coworker for months. And now he's moving... across the country. I've got one shot to make my move. We're all holed up in this amazing house upstate and tonight I'm going to sneak into his room and finally Make. Something. Happen.
So I go for it. I climb into Luke's bed and the kissing is so much better than I imagined. Why did we wait so long to feel this? I moan his name and Bam! He jumps out of bed. WTF? It isn't Luke. It's his twin, Noah. I don't even like Noah. And he certainly doesn't like me.
This will NEVER happen again...until the next day against the barn door. Why can't I stop seeing him? It will never work. We're complete opposites. Enemies with benefits is a thing, right?
But what happens when I start to want more?
