You try to pull back your newly formed sheath and shudder with pleasure. You begin a stroking motion and watch as your once mushroom-shaped head, now pointy, rises out of the sheath. Your new pointy cock rises out of the sheath beyond your belly-button and stops at you chest.
On a sudden impulse you run you tongue along your pink shaft and shudder. Unaware to you a furry tail has just form above your ass. Sucking the tipping stroking the base, you taste your own precum whilst your hands find your new knot.
As your hands rub your not you shudder again, and again. With each shudder you grow harrier and your face grows longer and your ears move up your head and your legs reform.
You continue to stroke your pink shaft, relentlessly sucking as well, and stop as your black doggy nose forms and you catch scent of a female in heat. You run from the room and find that the scent is coming from the room accross the hall.
When you burst through the door your dick throbs and you fall to all fours and run to the German Shepherd bitch standing with her back to you in the center of the room. You hastily mount her and gouge her ass, probing for her waiting cunt. With a satisfying slurp and pop, you slide into her all the way past your knot and hump the bitch- all the while your mind degrades. But you're happy; your bitch is fucked and your new equipment works much better than the old stuff.
