As you look closer, you see that Harry looks to be growing hair all over his face, but what really catches your attention is the look on his face. He looks like a excited puppy, tongue hanging out of his mouth as he pants. Harry's eyes look kinda dopey and relaxed despite the exercise. Before you can think too hard about it you hear a slight hiss from the guys in front of you and you watch as their tight suits begin to bulge and swell around the crotch, as if they were being inflated. It's such a relaxing sound, and as you listen to it you begin to smell the faint whiff of piss. The line of guys in front of you just pissed their pants.
The though barely registers now, as you find yourself consumed by the same blissful feeling as Harry. It feels so good to relax and run. Just follow the leader. Don't think or strain yourself. You don't notice as fur begins to sprout all over your body. It's not important.
Suddenly, you feel a warmth spreading across your crotch and your suit's lower region begins to change into a large, thick, poofy diaper. It feels you nice and safe. Your too engrossed in your own pleasure to notice as the rest of your team changes. Eventually you come to a stop and you stand there. A diapered werewolf ready to listen to whatever order's your given.
