it all started with rimming

[NASCARaddicted]

What about this:

for some reasons, brother and sister sit together. Maybe they had a private party and they are the last 2 that are still away at 1 am. They had some alcohol and are a little bit tipsy (but not drunk), when they start to talk about sex.

Sister grins and asks brother, what is his biggest fantasy, or what he loves to do the most during sex.
Brother blushes but he doesn't want to tell it to her - unless, she doesn't tell him what her biggest fantasy is.


In the end, they decide: they will write it down on a sheet of paper, and then, they will exchange it - so they don't have to say it out loud.

So they do. However, once they read the paper, they are surprised.

Brothers biggest fantasy is: "to lick a womans butthole", while sisters biggest fantasy is "having my butthole licked by someone (no matter if male or female).

They both have the same fantasy. Maybe it is the alcohol, but brother offers sister to help her fulfil her fantasy - especially, since he has exactly the same.
Sister is insecure about that, but brother tells her, that since it neither includes a penis, nor a vagina, it can't be called sex - and so it wouldn't be incest.
Sister gives in. They go to the bathroom, where sister can clean herself (just to make sure). And then, brother goes down on her and licks her. Maybe she even cums (who knows, either she is so turned on, or she worked her clit, while he licked her). Also, brother jerked off, while eating her butthole and shoot his load everywhere on the floor.

The next morning, when they are sober again, they can't remember. They clean up after the party ... and they find the sheets of paper again. When they read them, they start to remember. Brother and sister sit down to talk about what happened. They both think that it was only because of the alcohol, and they would never do it again ... "even though it really can't be called sex ..." says the brother.
"You just say that, because you want to do it again, right?" asks his sister.
Brother says nothing - instead, he reaches forward and unbuttons her jeans. Sister is surprised, but when he pulls her pants down, she doesn't stop him.

This happens like 2 or 3 times and they both enjoy it. But of course, after some time, brother can't help himself ... his sister surely has a nice butthole, but the pussy is also very sweet, so he touches it, too ... and he licks it. Sooner or later, they have full sex .... and it all started with rimming

You say sex, but I could highly imagine that with fetishes like this it could easily lead into anal before vaginal sex. But the whole concept is a great idea.

Also, it's important to remember (at least I think) that the lines between "right" and "wrong" become fuzzy after a while. When you've gotten used to something, it's easy to think that it's normal enough. So after he's gotten used to rimming her, and the taboo aspect goes away, it's a slippery slope to other things.
