You awake to find yourself in a pet store; locked in a cage with no way out. A wave of fear washes over you and you scratch at the walls in an attempt to free yourself.
"Sarah" an unknown voice calls out "the dog you found woke up!"
They then step into your view: a young woman around the age of 19 and she looks like she's going into a goth phase.
"God look at the thing, it's scared shitless! Heh, stupid mutt"
"Don't call it that lilly!" Blurted another voice who you can only assume is Sarah "it was all alone and it looked like someone had raped the poor thing!"
"Then why did you bring it here? It probably has some kind of disease and i'm not going to deal with that today"
"I already told you we're not doing that! Because if it was raped then whatever psycho that did it is still out there and... well.. you know how I feel about that kind of stuff"
The two girls trail off in your mind as you begin to realize that you're hard as a rock, it's bigger than before, and you are starving. You don't waste another moment to get your muzzle around your shaft and begin bobbing as hard as you can.
You cum over and over into your mouth for a good half hour, savoring every last drop. As you let go you realize that you're still hungry, still hard, and you got cum on your belly.
Before you can go delving again, Lilly comes into view with a bowl of dog food. She unlatches the cage and lays the dog bowl down in front of you. But before she can close the cage back up she rears her head in disgust. "Holy fucking shit what is that smell!"
Hesitantly, she inspects you until her eyes bulge in awe at just how massive you canine cock is. "God it's the fucking dog, is that it's musk? And jesus that thing has to be 12 and a half inches long! And that girth! 5 inches at least!" Sensing a hint of arousal in Lilly, you jump at the chance (literally) and lick her face whilst simultaneously exiting the cage. She then proceeds to push you off into a corner and wipe off her face only to realize that she got more shmutz on her face than before.
"Eww what is this stuff?" She then dawns a face of horror as she realizes that it's most definitely a happy helping of dog cum. Running and screaming, she open a door to presumably go and take a year long shower with a side of therapy. But you don't really care as you too can smell your musk and it's pure heaven. Taking the whole thing in your mouth, you start to cum and cum and cum and cum. Its the longest you've been without stopping and each time you go for a hot meal it seems to get longer and the need becomes stronger. Your human instincts are far gone but eventually even all the dog instincts will be gone, other than the need to suck and cum deep into your muzzle. But let's not worry about this right now, let's go check on Lilly!
