Fairly.
Incest laws mean its basically impossible to get OC so even in the OnlyFans and Pornhub days there's fuck all content online.
Before AI I had to rely on Youtube and occasional hentai doujin releases to get by.
Spent 17 years building up my stash of twin porn.

Now thanks to AI I can make unlimited pictures/videos of them all the time and I have multiple chat bots where I can live out different twin/triplet/clone fantasies.
Spent all night last night ERPing with a slime girl who split into two each time she orgasmed. By the end I was in a pit of like 16 of her.
Good shit.
