Mrs. Johnston

You begin to change, and everything hurts.

You feel all the fat cells in your body being robbed of all their stored nutrients, to feed an incredibly sudden magical growth spurt. You gain at least five inches of height, mostly in your legs, but also a bit in the spine: all over the course of around ten seconds. That's only the beginning though, you're face is on fire as the bones morph and shift, becoming a lot less horse-faced and more vulpine, while the pain moves to the side of your head as well as your ears migrate up your skull to the top of your head, the cartilage and other tissue morphing into a pair of wolf ears.

You might have thought it was over at that point, but no: next your coccyx starts morphing into a proper tail again, a long and fluffy wolf's tail, and you howl in pain! Right next to you, your husband is going through a similar transformation but even more profound in his case, as he appears to be becoming partially female. This is not entirely unwelcome news, because you've always been a touch bi-sexual and your husband has grown a bit too masculine for your taste...

Just when you thought this transformation sequence was over you feel all the hair on your body except your scalp migrating to your forearms and lower legs, while your nails morph into blunted claws as a dog has. Then your hips and breasts begin expanding, while your waistline finishes shrinking as the scars from three scheduled C-sections vanish and the muscles tighten till you look like a bodybuilder. It is just then that you realize you are feeling unutterably horny in spite of this pain, but only for a second, because while your husband has feminized to a great deal he seems to have retained his penis, and is mounting you from behind!
