FtM gender swapping sequence by Risutena, a long-defunct pixiv artist.
Someone recently up'd a few of their missing works and, in adding them to my archives, I realized I had this laying around from back in the day.

Kinda sketchy, but since a couple people expressed interest in their missing works, here ya go. No way to grab whatever the title used to be, unfortunately.

I wish the female gender bender was filled with actual female gender bender more often.

I'll give translating it a try sometime.

Interesting, I remember watching a couple of pics from this artist before but never knew the source.
