>>101150995It's a trust/intimacy thing. (Hopefully) there is no one you could be more emotionally close to than your family, and incest takes that to the highest conceivable level of intimacy. It's idealizing familial bond/love and tossing in sexual elements cause I guess you're just fucked in the head like that. I never really got it with Gaz/Dib since they don't actually seem to care about each other that much, but I suppose the incest just implies there are unspoken feelings.
>>101214191I have three sisters too and I'm fine with them. The thought of fucking them repulses me, yet incest is still one of my biggest fetishes. I guess it's one of those things that hits the right buttons in fiction but sets off alarms in reality.
I suspect people who think having real siblings discourages incest fetishism just have a shitty relationship with their siblings, which just seems like a tragedy to me.
