You watch as both your hands turn into four digit like paws with claw like fingernails. Feeling your legs start to change you flop down on your back and lift them up in the air as they reshaped themselves to be bipedal wolf legs. While this was happening your face elongated into a muzzle like snout filled with sharp canine teeth and your ears became pointed moving to the top of your head. As the physical transformation happened a renewed feeling of horniness surged through your new animalistic body, your cock becoming hard again despite having come twice already. Panting heavily you stick your paw like hand down the front of your diaper again, grabbing your throbbing meat. Pumping it furiously you jacked off with renewed vigor spurred on by your wolf transformation. You suddenly began to growl and grunt not because you near your release (even though you were) but because you felt something coming out of your rear. You thought you were pooping out a massive turd but it turned out to be your new furry tail sprouting out through the back of your smelly diaper. Feeling it swished back and forth you picked up the pace before coming to an earth shattering orgasm that caused you to howl loudly in pleasure as you achieved ejaculation. It was so intense that it caused you to push another brown log into the seat of your already filled padding, the diaper sagging further.
Relaxing in the blissful afterglow you stared down at your new wolf body, loving the way your sleek black fur made your white padding pop out. Wriggling your hips in happiness you reach down and gently groped the front with your hand while placing the thumb of the other in your mouth and sucking on it like a baby. You didn't know why you did it but after putting on the diaper and soiling yourself three times it just felt right to you. Speaking of your mess thanks to your new higher sense of smell you were practically overwhelmed by the overpowering stench of the huge load you made in your pants, and rather than be disgusted by it you reveled in the scent of your own feces.
You were taken out of your thoughts by the sound of the doorknob turning. Too late to do anything else you just lie there as the door opens to reveal an male anthro wolf just like you but with sleek silver gray fur instead of black. But what really caught your attention was the fact he was also wearing nothing but a beast diaper.
"Ah I thought I heard a howl come from in here. So you are the mysterious intruder who entered the mansion and has been snooping around" he said with a grin, "Seem like you managed to wander into my personal diaper storage room, tsk tsk" the wolf shook his head with a sigh. "You really shouldn't have put one of this on. For you see my diapers are enchanted with a bit of myself or my soul if you will, along with bits of my personality like my love for diapers, babyish tendencies and slightly insatiable horniness. And when you donned one you were permanently transformed into one of my kind...so I guess that means you're the mansion's newest resident as you can't ever leave now."
You grinned behind your thumb not particularly unhappy by the thought of living here forever.
"Since you'll be my new roommate you should probably know my name is Ralph" he said with a pleasant smile.
Smiling back at your new friend you wondered what crazy or weird thing was going to happen next.
It was then that Ralph...
