Dan watched as his body shifted and contorted, blotches of black and white appearing on his skin, and his stomach growing a set of udders. His mind raced. He couldn't believe that his mother and sister would even think of doing this to him, much less have the ability to transform him into a cow.
His sister Kat laughs as it happens. "Look at his tiny dick!" She says in tears.
As she says this, he looks down just as it happens. It starts shrinking into itself. Dan tears up and tries to speak, however all that comes out is a deep moo. He starts gaining weight and eventually breaks the chair he was caught in and gains enough weight that he can't even really pick himself up. his plump body makes way for a plethora of more changes such as hooves, a snout, and a tail sprouting out from just above his ass. Soon enough, the transformation is complete as he becomes a full grown milking cow. His mother Janice and Sister Kat laugh more as they walk out of the shed, pleased with themselves.
Dan moos constantly throughout the night, thinking to himself that he can't believe that they actually did this to him. He seems to almost give up hope until he feels something tingling course throughout his body. It seems similar to what he felt when Kat started the transformation, and this becomes pretty apparent why whenever the transformation curse seems to lift from his body, however Dan passes out from the sensation.
When he wakes up, some things feel off, but he can't quite place them until he feels his body with his human hands. Human hands? Yes... Human hands, but something seems wrong. His body seems softer and more sensitive than normal. His hair feels longer and his chest is heavy, not to mention, he feels a little older now. He's a woman now and because of this, she seems to have inherited, or more accurately, activated a dormant gene is his genetic data.
Dan seems to enjoy the power that surges within, and with it, there only seems to be one option. Revenge.
