As a show of good faith between ponies and humans following the linking of their worlds, pony guards have been sent to help in peacekeeping missions on earth, and vice versa.
Auburn Sunrise has been part of a human base on earth for weeks, now, bunking with a straight laced private named Bradley. She's far away from any stallions, and while she cares about her duty, she's becoming extremely bored. Also, humans are kinda cute, Bradley especially!
Can she get through another day without begging him to make a move on her? No!
