My brother and I are both bifags who grew up with abusive religious parents who were highly. So not only were we not allowed to date girls, but they kept a close eye on our computers/phones so we couldn't even look at porn. And we had minimal privacy too... like, we couldn't take too long in the bathroom or we'd get accused of jerking off.
So pretty much the only time we had any privacy or time to ourselves was late at night, after our parents went to sleep. Me and my brother shared a bedroom, so I guess they figured we'd keep each other honest? I'm sure it never even occurred to them that instead we'd end up jerking off together. Which of course naturally led to exploring each other's bodies and "helping each other out."
So I wouldn't say that either of us really had an incest fetish, or that we were even attracted to each other, really. We just had no other sexual outlets so we got progressively more gay with each other.
