camping with... buddie

Now, Buck really wasn't an early riser and he could sleep through so much, it surprised him sometimes that he didn't just sleep through the whole day. This day though, it seemed that he woke up to something that he hadn't ever woken up to before and he wasn't quite sure yet what he thinks of it.

At first he thought it was chirping of the birds, but he was quickly reminded that he would have heard that too if he left his window opened a bit at night. That wasn't new. Then he thought it might have been the branch that tapped the tent, in a very annoying pattern. But it was too soft to have pushed him out of the quite deep sleep he had been in, But as he moved slightly, getting ready to look up to try and find what else it could have been, he noticed.

He noticed how there was something hard pressed to his ass while a hot breath softly puffed to his back.

Or: Four men go camping together and share two tents, only for Buck to wake up in his sleeping bag to find something hard pressed up against him.
