Not bad. The art seems a little generic, but it gets the job done. In terms of story, it's again, a bit generic, but does have some neat quirks to it. I'd say the best feature is the monologue of the protagonist. The slow degradation of his sense of self was interesting enough to keep me reading despite being low on the sexual content I originally was looking for.

The transformation seemed rather slow. I personally really love slower transformations, and the way this ends leaves room for many interesting possibilities for a sequel, if the artist chooses to do one.

Not bad at all!

Although having the protagonist immediately fall under her control with almost no resistance, and now fully cooperating? That's a bit boring. I like a bit more tension.

The gradual change is handled really well, makes this stand out.

I've seen this before, but I never could find it again.

Thanks, OP!
