Armpit fetish. I have this fetish, and have no idea why, or why armpits are arousing. But they are, and games and videos with it just scratch an itch that other games don't.
OMG I saw a video once where a guy took a soiled diaper from an age appropriate user and licked the scat out of it. I still suffer from ptsd from that one.
Like, the games that are so obviously a self insert fantasy that goes even beyond just having sex with women. Like, I need to one shot K.O her ex boyfriend, save my entire family from financial trouble, every woman who sees my giant dick falls in love with me. To me this fantasy is just so infinitely more pathetic than some game where you are a loser and have to fight for the erotic content.
