Digging beneath the tissue paper you come up with what appears to be a dog's collar and an odd leather jock... upon closer inspection you note the collar has a tag with the name BRUNO on it and the jockstrap has a quarter-size hole in it's pouch. "What the...?"
"My secret admirer must think I am some sort of exhibitionist if they think I'm about to bound out the door in this!" you say to yourself and dump the contents back in their box and sit down in front of the television.
After several minutes you note that you have been absently scratching yourself as if your clothes were giving you some kind of rash. You strip off your tight-fitting wife-beater in the hopes of some relief and feel a bit better. Soon your sweatpants follow suit leaving you sitting in your meager tighty-whities but even they seem to be irritating you.
Although you have a decent muscled physique (albeit short in stature), you feel awkward sitting about with no clothes on and find your self slipping into the once boxed up jockstrap.
The leather jock felt cool and soothing against your skin but the strap overall was quite large. Rubbing the front pouch you soon became hard as your manhood struggled to escape the pouch through the hole provided. Was it your imagination or was your cock getting bigger?? Moments passed and the "head" of your little soldier was peeking through. Your balls also were filling the space the ample pouch provided and soon your body started catching up!
You stand and swagger (swagger?) to he full-length mirror in the hall and gaze in awe at your now stocky form complete with a full compliment of body hair making you look like a true leather bear. "Wow!" Your pouch hung heavily with the monstrous package within and it struck you that the pouch look more like a big dog's sheath!
By now your baseball sized balls were filling your muscular frame with high levels of testosterone making you feel the need to finish the look...
The collar was once noticeably for a much broader neck but now it look perfectly sized for you. One <click> and the collar was in place... "Man this is really wwei... wwhh.. woOf Woof? WOOF?! WOOF!!"
Your voice! You could only now bark like a dog!
Trying to remove the collar proved impossible! Bounding back to the mirror you see the transformation is complete - You have become a well-hung, muscled freak named BRUNO who believes he's someone's DOG!! The revelation causes your enormous sheath to become hard and drip with throbbing moisture and your reach to relieve the building pressure.
Suddenly a distant (almost inaudible) sound makes you jump to and you realize that your secret admirer is calling you to the park - WITH A DOG WHISTLE!
