    Summary

    During a long trip in the Impala with Dean, Sam ends up needing to use the bathroom. But Dean refuses to stop with the excuse that it'll slow them down and that he'd rather reach their destination before nightfall. And either way he forced Sam to put on a diaper before he left so if it's that much of a problem he can just use it.

    Unfortunately Sam is quite stubborn, wearing a diaper is embarrassing enough so he refuses to use it. But he can only hold it for so long, and his big brother can be oh so convincing.
