You look at the connection between your groin and the wolf body. A flap of skin seems to be connecting it.
As your hand stroke this flap of skin you feel waves of pleasure and the wolf groans. You legs tingle strongly but you are content at feeling the newly formed skin until you notice the wolf is starting to try to squat.
You realize that while you were paying attention to that skin flap your legs have been reduced to large wolf balls. Massive and huge these testicles look out of place and in the way of what the wolf starts doing, letting his feces flies. You watch in disgust as a little bit of shit land on your legs. But, they start shrink almost in time with the logs coming out of this wolf.
And then it's over, you stare in fascination and mortifition at the covered testicles that once were your legs. In shock you cup and rub the wolf's balls. You can still feel them but the touch feels so different and good.
The wolf looks down at you with a coy lupine smile as you play with your former legs not paying attention of what is happening around you.
