I don't know if this counts, and it's AU fic srry, but in Hearthacking by PegasusRider, Naraku works in the same building as Sess and Kag, and is affectionately termed "Naraku the Nerd" by Kagome (I think this says it all about his character lol!); and at one point in the book Naraku helps Kagome to build a paperclip catapult to launch at Sess, after they start a paperclip war in the middle of a boring meeting. He also tattles on Sess after Sess acts like a jerk lol
Either way if you haven't read this fic yet you're missing out! It's got to be hands down, one of the funniest SessKag fics of its type XD I simply adore this fic and always find myself going back to read it again and again when I find myself in need of a laugh
