It starts with a joke.

In bed, my boyfriend Adrian talks about sharing me with his best friend, Elias. I laugh and call him crazy, but a secret, warm thrill curls in my stomach.

Then we get stuck.

A storm hits during our camping trip, and I'm stranded alone with said best friend. And there's only one tent. In the tight, dark space, pressed into Elias, Adrian's crazy joke feels less like a joke and more like... permission.
