Suddenly your brother Mike opens the door and you hear him stomping up the stairs to your shared bedroom.
Panicking, you stand up and try to pull your pants back up, but you don't make it in time. He comes in the room, and there you are standing, fumbling with your shorts, with a long brown donkey tail hanging between your legs.
"Hey what is that," he says as you back slowly away. "Let me see it."
He starts walking around you trying to get a closer look, while you keep turning to face him with a big red blush. He finally grabs your shoulder and looks down your back just in time to see your new tail twitch in agitation.
"It's nothing, it's...just...I..." you mumble pointlessly.
"Dude, what IS that?!"
You shudder, startled, as he picks up your tail in his hands. You can feel his firm, careful grasp around it as he lifts it up and moves it around. You look him pleadingly as he holds and studies YOUR tail. You continue blushing.
Finally he releases it and it swings back down over your butt where it belongs. You swish it a couple of times in slight relief.
"It's real, isn't it."
You nod.
"It's a donkey's tail, isn't it."
You blush harder, and nod again.
