1. Tag Search
I just realized, that there is actually a "tag"-search, if you click on a tag.
The results appear to be different from a normal search for that tag.
Example:
https://chyoa.com/search?q=Bisexual&type=story - 74 results
https://chyoa.com/tag/Bisexual - 52 results
Although apart from finding and clicking a specific tags,
or knowing the url and modifying it by hand,
i see no way to search for the tags on the website.
So unless we place a suggestion for an additional explicit "tag" search option within the search, i would stick to the searches that you performed already.
2. Wrong link
Big Beautiful Women
13 Stories
The link opens up
https://chyoa.com/search?q=Bisexual&type=story for me.
3. Additional tags that i can come up with:
Breast Growth
Celeb, Celebrity (as alternate versions for Celebrities)
Cheerleader, Cheerleaders, Cheerleading, Stunt, Handspring
Dickgirl
Doctor
Domina, Dominatrix
ENF, Embarrassed nude female
Fake breasts
Geek
Growth
Implants
Natural, Natural breasts
Nerd
Secretary
Shower
Slut
Transformation
Transsexual
Virgin
Hair colors
Blonde
Brunette
Redhead
etc.
You could create a list (subchapter) of tags for specific
celebrity names,
movie names,
book names, etc.
Examples that I have used:
Anna Kendrick
Britanny Snow
Jennifer Lawrence
Keira Knightley
Pitch Perfect
