The full procedure takes roughly an hour for you and your wife. Durring which you can feel every inch of your body crawling and itching as it is reconstructed into your requested new form.
You can feel your bones shrinking and lengthening in places, you feel your hips widen and your back arch to accommodate your new ass. You feel how delightfully heavy your 2 new boobs are, and then how a few more rows of teats spring up onto your torso. The second and third rows even have a bit of breast tissue behind them, making them push out into modest B cups and A cups respectively. You figure this was inevitable to hapen, but are happy they at least can be hidden by a baggy outfit or a wrap of some kind.
Then the changes get internal, as your stomach and intestines shift around to make room for your new human pussy, which quickly develops uterine didelphys as it splits of into two branches. It then turns completely canine in both form and function.
Your face is next, as your features become feminine and your hair lengthens considerably. Then something unexpected happens. Your spine pushes down further into your lower back, and pokes out, as skin, fur, and muscle quickly grow around it as it continues to lengthen into your new, german shepherd's tail. "Oh no" you mutter, feeling your new tail underneath your ass. This definitely will make your wife pissed off at you now.
It is a bit exciting, knowing that you can now become your wife's bitch/owner though. And while she will be mad about the tail, you wonder if she will be happy or mad once she figures out that you are not a normal woman with just a dog tail and teats. Will she want to impregnate you? Or will she deny you out of frustration and anger for doing this without telling her? You can only hope it isn't the latter.
As you think about your wife, your nipples harden and become fully erect. You also cannot stop picturing you amd your wife in the kitchen, when she suddenly knocks you down to the ground and mounts you. The thought of her knot being inside you is turning you on to no end as the mental adjustments you have requested for finish being applied. You even begin to finger yourself a bit, just to get a preview of what you will be in for later on.
When the hour is up, you hear the intercom instruct you to slowly stand up and get your new center of balance in order. Then the door is opened and 2 handle bars extend out from the walls to help you stand up.
It takes you a couple of minutes to get use to the new shaking and jiggling of your brand new assets, however you are very satisfied with them. Your concerns about your additional rows isn't nearly as big of an issue as your boobs are large enough to hide them below if you wear a loose top. Even a form fitting outfit will be ok if you cover them up with a wrap of some kind. The only thing you cannot wear are tops that show of your belly, as 2 rows at least will easily be seen then. Bikinis are also out of the question, unless you want people to see them.
Taking your first few steps is a slow process, but you soon get use to it and walk out of your chamber into a larger room. You are then greeted with a beautiful looking serman shepherd who immediately scowls at you and barks. You do not need a translator to know that she isn't happy with your "last minute additions".
"You... what the hell do you think you are doing!" scolds your wife. It is a bit amusing to watch the sexy male dog ridicule you in your wife's voice. She stares your naked body up and down, while your gaze is transfixed onto a single, red spot on her body. You cannot believe you are married to such an attractive male. It excites you just thinking about how lucky you are to have him for a wife.
Speaking of your wife. She stands up onto all fours and walks around you to get a full view. "Wow, you went full blonde bitch bimbo, didn't you."
"I did not! Just because I like the hair color doesn't make me a bimbo." You shout with an unprecedented amount of anger.
"Chill honey, it was just a joke." Says your wife as she steps back from you. You are apparently more sensitive to that than you thought. You quickly calm down and apologize for being so mad all of a sudden. It is weird how you can hear your new voice talking, and do not fully realize yet that the woman speaking is you.
You squat down and stroke your wife's neck and back, which apparently she likes as her tail begins to wag happily. "Sorry about the tail, I also didn't know it would be included" you admit. Inside your head however you are fully obsessing over the smell of your wife's body. A welcomed side effect of being part dog now. Your own tail is wagging a mile a minute too.
"Hey, what's that smell?" Your wife says as she starts sniffing the air. She is inexplicably drawn to it and immediately begins sniffing around the room to find the source, not knowing that it was right beside her. She nearly gets back over to you when you are interupted by the police cheif bringing you new clothes and a collar for your wife. You are put into an unmarked car and brought to a home well out of the city where you can hopefully live in peace and safety, living off of a fat monthly stipen check for your expenses until you are due in court.
The house is beyond decent, and the neighborhood is quiet and gated. The property has a tall fence surrounding the back yard, as well as an inground pool and a shed. All in all it is a very nice place to live in. There is even a big, dog friendly, park nearby. It seems like you lucked out with this happening, if only for it not being at the cost of both of your identities, and your wife's humanity.
