(F4M) id love to do a transformation rp with a dominant male!! Plot below

My idea.. sorta.. is that either MEeee or youuuu have an ability to change from a human all the way to a feral and everything in-between!! So likeee you can simply human doggy ears and thats it... you could be an anthro... an anthro with no tail.. alllllll the way up to a full on feral doggy!!! The thing is whether it is me or you who can do it, the other person doesn't know about it, I wanted the plot to kind of unfold to see how the other would react when the person who can transform exposes this power!!!
