Yes, it could be. I don't know if you have played a game called Good Girl Gone Bad, in that game, depending on your decisions, you can play a story where the protagonist lives a normal or vanilla sex life. On the other hand, if you massively corrupt the character, with your decisions, you can end up having more intense sexual scenes.
I intend to do something similar.
Shortly after launching the game I was asked about the tags I intended to add to the game and, since I have in my head scenes and character development arc, but not fetishes as such, I looked up different tags used in erotic game webpages to see what I plan to include in the game:
Fetishes that could be seen soon: Corruption, Exhibitionism, Voyeurism, Trans, Teasing, Virgin, Prostitution, Public Sex, Sexual Harassment, Titfuck, Anal Sex, Interracial.
Later I might add these others: Ahegao, Gay, Lesbian, Male Domination, Pregnancy, Sex Toys, Milf, JOI.
And for much later these could also be added: Bdsm, Bukkake, Female domination, Footjob, Group sex, Humiliation, Multiple Penetration, Spanking, Stripping.
Obviously any scene in the game has the option to move on or not.
These are not all the tags the game will have, because I'm sure I can think of more stories or scenes to put in, and it's also possible that some of these tags will end up appearing before their time, who knows, but it's good to get an idea.
