Did the potion transform a male or hermaphrodite into a pure female while magic of some kind masturbated him/hir till ejaculation then catch the sperm and re-inject it into his/hir pussy or just ejaculate his/hir male-hood away?
Or still unkown was it a female that grew a dick then masturbated it away?

If so I find that fascinating and would like to see more.

The art however needs some improvement and a little more visual to solidify what happened during the story.
Either an internal shot or make some motion lines to indicate the flow of semen or a before potion picture.

Overall concept good work. :)

her beak is missing on the last page

I think the artist was going for perspective on that one, beak is aimed right at us with mouth open, like a piece of paper if you turn it sideways it nearly disappears.
But I get what you are saying, it is curved so it should still be partialy visible even from that angle.
