You Like It When I Call You Mine?

On a weekend trip with your friends, you let someone else do the planning for once and rent cabins for all of you. Most of your friends have partners though, so you're left paired with that one friend you've had a crush on for years, who happens to be the only other single person in the group. After a whole day going nuts seeing him get dirty and have fun, you finally go to the cabins for some space. But you can't take your pants off, you want to shower and he's just there and... there's only one bed.
