You've actually raised an interesting philosophical issue (as strange as it may sound in relation to trans porn). Where is the line where "transformation" becomes "replacement"?
- I've written a couple of times in this forum thread that, personally, most stories lose me somewhere around the first third, where the complete transformation occurs and the rest of the plot unfolds with a shy nymphomaniac who bears no relation to the original character. For example, like in "A (Not So) Temporary Roommate," where by the middle of the story such radical personality changes can only be attributed to hard drugs.
- Similar frustrations are caused by stories like "Pick up an alien/magical object and in a few frames turn into a dumb, lustful blonde" (a common trope of Telsis) or "Walk into an abandoned house, which turns out to be the hideout of a witch who, with a snap of her fingers, turns you into a submissive, busty maid." Well, if the character had been blown to bits at that moment, and a chick from another reality had been teleported in their place, the situation wouldn't have changed. (It's a different matter if, with a snap of your fingers, you find yourself trapped in the body of a busty maid, but that's another story, the kind Kannel loves (and doesn't like to end)).
- Hypnosis, magic pills, cybernetic programmingā90% of the time, I find them equally captivating. It's interesting when there's an element of loss of control and some kind of internal struggle and mental turmoil are voiced. But more often than not, this happens as a crude abbreviation of the narrative and is barely distinguishable from the instantaneous transformation. (LilTKit, surprisingly, has both options in her stories.)
But, on the other hand, if there aren't radical changes, then what's the point? These fundamental personality transformations are what we read these stories for. It's unlikely that anyone will be drawn to a character portrayed as a simple man who doesn't take care of himself, is ready to stand up for himself, and rudely flirts with girls, but somehow in the form of a busty bimbo. In my opinion, NovelChef and ds1000 do this best ā their characters, at each stage of their transformation, are aware of themselves and their situation, forced to act based on the situation they find themselves in, gradually transforming into a different person. But at the same time, we can trace this unified line of how and why the guy from the first scene became the girl in the last, and why exactly this girl. This is unlike Need for Speed, where literally in one scene the hero suddenly decides he wants to suck dicks, or Latina in Needs, where from the moment he dresses up as a maid, the hero begins acting like a teenage girl.
