Circa 2014. Each of them fuck their own brother and end up swapping brothers for sex too. And no, it's not Brotherfuckers by Xarth.

Okay, again now I'm not sure whether I read this on here or on another site. The story was more or less along the same vein as "Trading Brothers" by the legendary Wayne Gibbous, but they mutual masturbation between the brothers was definitely there.

Are you sure they were all related? This sounds a lot like "An almost perfect awakening"

I think that was the title, it was a long long time ago.

Main character is best friends with a guy, they discover the guys two sisters are sleeping with each other. Peeping on them. The girls find out and want to sleep with them but first make the brothers go down on each other while they watch to make things even.

Unfortunately, not that one. I believe it must be a deleted story. I saw a translated version of it in a blog, but the blog's admin won't respond to any questions about the original.
