With the oily, hairy, gross material, you assure to yourself that you're not going to be putting a pair of these disgusting things on. Besides, the look like they're about three sizes too big and if memory serves you'll turn into some kind of huge anthro animal freak of you put one on. While you don't want this to happen to you, you can't help but wonder what the effects are.
You then realize you have neighbors. Neighbors that all hate you. It seems you can't go even a day or two without one of them complaining about you and Kurt or asking your landlord to kick you guys out. And why should they? They're all college students like you guys, so what gives them the right?
You look at the clock. 9:30. Most of your neighbors will either be out partying or staying up late to study. You grab the entire box and head out into the hall, closing the door quietly behind you. Then, you walk all the way up and down your hall, leaving a brief on each doorstep and knocking once lightly before running to hide in the next doorway. The neighbor will usually look down, see the brief, have a questioned look on their face, grab it, and head back into their apartment. You do this all the way down the hall until every pair is either in the hands of a neighbor or left on the doorstep because said neighbor was not home. All in all, you estimate that eight neighbors grabbed pairs.
Once you are back inside your apartment, you wait. A minute passes. Then five. Then ten. You are about to think the whole thing was a dumb idea when you suddenly hear a yell coming from the apartment next to you. Putting your ear up to the wall, you hear stumbling footsteps that grow heavier and produce a louder, deeper sound with each stride as the point of impact on the wall gets higher and higher. Eventually, the ruckus stops and you hear silence.
These same sounds repeat seven times over the next two hours. You guess that your plan worked a little too well. You shudder and realize what you have done and regret it almost immediately.
Then, suddenly, each of the eight doors open simotaneously and you hear eight heavy pairs of feet, paws, hooves, trotters, talons, whatever, hitting the hall floor at once. You hear a scream and smaller footsteps, but the eight pairs speed up and you hear the sound of something heavy hitting the floor. You hear the ripping of clothes and the sound of something being slid on.
You walk quietly over to your door and open just a crack, peeking out. The sight almost stops your heart. You see eight gigantic, muscular anthro animals all wearing briefs and shoving another pair on one of the neighbors that wasn't home. A bear and a lion hold the man down while a stallion and a panther shove the briefs on the man. Standing behind them, keeping watch on the elevator, are a wolf, a German Shepard, a pig, and some kind of lizard.
The man bucks and hollers as his body increases in size and muscle, filling more of the hallway as his frame becomes one like a bodybuilder. All of his skin takes on a thick grey appearance as his hands and feet puff up and round into sort of elephant feet. His gut swells out and hangs over the band of the briefs as his things and arms become almost cylindrical. His ears pop into huge leathery gray things that hang off the side of his head. He sneezes loudly and his nose becomes huge and thick, lengthining and hanging down over his mouth like a trunk, from which two tusks grow. There is a crack and the anthro elephant adds three feet to his height.
His eyes glass over and he stands up, easily the largest and most muscular at almost nine feet tall. He stands watch with the other anthros near the elevator, the remaining pair of briefs clutched in his hands.
