TL;DR Sex is personal, incest play is fun, incest play =/= real incest, sex is a part of self expression, don't base your politics on disgust, change the channel if you don't like what you're watching

(also, this is already a massive dissertation but i wanted to add that incest fetishists are also very much not into actual incest. i've yet to meet one who actually wants to get it on with a blood relative.)

this is because sex is a personal, intimate thing that can be (and often is) used to express parts of your personality you otherwise keep away from daylight. it's good to know yourself, know how to express yourself, and know when to let others have the space they need for themselves.

ultimately, it *is* harmless. the point of the original post is to warn against basing your politics on your personal sense of disgust. not everything is for everyone, but when you see something you don't like that's harmless, it's better that you move on and go elsewhere than rail against it.

if i could put it in a single thought, i might say "what if i got to be the little sister i never was? what if i got to be loved and accepted in that way? what if i got to be comforted in that role"?

given that incest play is concerned with family roles, it's also concerned with a psychological motivation to reclaim who you are from your past. if you've struggled with your feelings about your place in your family, it can lead to things like incest play later on as a coping technique.

incest play is also a roleplay of family dynamics, which for trans people can mean affirmation in a role they never got to grow up in. there's a bittersweet comfort in being able to call the girl you love your big sister, or in her calling you her lovely little sister. it's very sweet that way.

hi! so with regard to incest play, the appeal comes from a few different factors.

it's taboo, so it's more likely to be the subject of fantasy in the first place. this is why media like Game of Thrones, which features incest, was so popular.

god watching that fucking broke me. she finally got it and she got fucking eviscerated
