You look over the nearest wolf costume. It's midnight black fur is super realistic. You decide that you and Jack might as well go as the same animal. "I'll take this one I guess." you say holding the costume up. "Great, I'll get it wrapped up." Within a few minutes you're on your way home.
As you walk into your apartment you find Jack standing in his boxers about to get into his costume. "Hey, you're back! Looks like we got costumes at the same shop." says Jack holding up his brown wolf costume, which is equally equipped as yours. "This is perfect timing on your part. These costumes are hard for one person to get on." says Jack as he starts to take his boxers off. You've glimpsed him naked before but it's still a little startling.
"Uh dude..." you trail off. "What, you're just going to let the condom flap down between your legs all night?" he says giving you a look similar to the one you'd give the guy who justed whipped his ass with Mona Lisa. "I guess not..." you say still unsure about the whole thing. "Come on man! Here, get undressed and we can help each other in."
Seeing no other real options you strip down. The two of you step into your costumes. The legs have some weird sort of brace in them. They give off the impression that you've got the digigrade canine legs, but balance is somewhat of an issue. Pulling up the waist you position your penis into the condom. At fist it seems to big but then you feel an odd pressure in your crotch, as if it was inflating and grown to fill up the canine member shaped condom. The red rubber in it gives off a very realistic appearance. After staring at if for a moment you realize you've got a massive errection. Wave after wave of pleasure is flowing through your body, though you resist it. However, Jack is well, jacking off.
You give him a moment and finally he stops, thought your cocks are still large and throbbing. The two of you help each other into the rest of your costume, tying up the backs and such. Finally you don the hood like mask and take a look at Jack.
He's amazing looking. The earlier balance issues you two had are obviously gone as you stand in the middle of the room. The masks are amazing, you two actually look like wolves. The wet black nose, the pointed ears, the long panting tongue.
Suddenly you realize that it's too perfect. Jack doesn't looked like a guy wearing a costume, he looks like a wolf standing in the middle of your apartment on it's hind legs. Nervously you reach behind your neck and search for the straps.
You take a long deep sigh. They're still there. You still refuse to believe it was just your imagination though. These costumes are too real.
"So Jack, shall we go to the party?" you growl.
