You've seen Jack in his wolf costume before. You didn't know quite where he'd got it from, but it was really well done. He always had an eye for detail.
So, when you get home, you take the costume out of the packaging and try to make sure it's everything you thought it might be.
Jack isn't home yet, so you slip into your room and strip. Your naked toes snake into the first leg, and already you're feeling warmer than you did in the store.
"Feels like silk." You mutter. You put the other leg in, and pull up the lower part of the costume. It's easy to put on the dog condom.
"Whoa." Your head spins a little at the pleasantness of wearing the costume. Like being at home in your chair with no one else in the house on a warm summer day. Relaxing and safe.
You pull the rest of the costume up and slip your arms into the holes, then awkwardly zip up the back. Finally, you put the head on and look through the mask's eye holes at yourself in the mirror.
You look like a fine looking shaggy dog with a nice large cock!
"Very realistic... " You say to yourself.
