>>82249727The two and only pairs I was with were pretty into it but I don't think it was really an incest fetish. The identical sisters had been through some rough shit and heavily, heavily relied on each other. They always slept in the same bed, they worked at the same place on the same schedule, etc because they'd get major separation anxiety.
The fraternal brother and sister were fucking wild though. They were hot white trash, the sister was a major tomboy. They just did not give an absolute fuck. We weren't in a relationship so it was really just fuckbuddies. Total bro-tier 'partycamping in the woods, wreck our cars offroading and fuck before we all pass out in the dirt' but they did make some attempt(but poor) attempt to hide it from other people.
The single twins I was with were completely disgusted by twincest and very against it. I've never brought it up to any of these people and never initiated the suggestion but it seems when it comes to twins - much like if you lost your leg - somebody is going to ask about it.
>>82249734Both pairs I was with were convinced me and my sister were fucking because apparently we acted a lot like them but they haven't been the first people to assume that. When we are together we are always dicking around, she rides on my shoulders, I shove her into things, we dance around, I fix her hair and she's always fixing my collar, will use the mirror/whatever while one of us is showering, huddle for warmth when it's cold, etc but I have zero desire for my sister. She's just a bro.
