I always find it hilarious and somewhat disturbing that people on here are way more accepting of incest rather than sharing.
I think that’s because incest is so far removed from real life. Most people aren’t into it IRL; more often than not it occurs unknowingly (siblings separated at birth falling in love without knowledge of their blood relation) or unconsensually (a parent abusing their children); and it’s a crime with pretty sever repercussions. It’s kind of like the porngame equivalent of murder in regular videogames: it’s everywhere, but no one bats an eye, because, as it’s not something they’d ever contemplate IRL, they don’t make a connection between the act as occurs in the fictional world vs. in the real one.
Sharing, on the other hand, is a more realistic fetish, if we can call it that; and it brushes up against another real fetish, which is cuckolding; and cuckold fetish is very close to non-consensual cuckolding, i.e. getting cheated on—which a lot of people have probably experienced
(especially on a site like this LMAO)—so it’s understandable in a sense that people would react more strongly towards it, even if it’s the “lesser offence”. People see incest in a game and think, “Whatever; it’s just a fictional thing;” but they see sharing and think, “I would feel horrible if my girlfriend slept with another man.” Kind of like people see someone get run through with a sword in a movie and go, “Cool!” but see someone get their arm broken and think, “Ouch! That must hurt.”
