Looking for an Attack onTitan fic?

Looking for an Attack on Titan fic that I found last Summer. It was an NSFW fic about the guys and girls at the boot camp going to seperate houses and having group sex to relieve stress. All I remember in the title was "Re" (as in prefix) something. Most of the popular gay ships (like jean/marco levi/eren and jean/eren) with alternating POVs. Pretty sure I found it on Archive of Our Own, it had multiple chapters. Any and all help is appreciated :)
