   Summary

   Nothing's been right for a long time, not since Mac and Dennis truly started getting older. Maybe it's Dennis' fear of aging, maybe it's Mac's newfound confidence, after leaving the closet for good. Whatever it is, something needs to change.

   Dennis has a plan. Get things back to normal. Get Mac under control.

   His control.

   In the battle that is Mac and Dennis, there's really only one course of action: Dennis has a war to win, and sex has always been his weapon.
