There is also this hentai doujin that does have a few pages of some Asuka/Misato/Shinji threesome with Asuka using a strap-on to fuck Misato along with Shinji
Also,there is only one image in MuchiMuchi Angel Vol.7+ does have Misato and Shinji double teaming Shinji but other than that,nothing else comes to mind.
Beats me why this threesome is not more popular than it is. However I do prefer Asuka,Rei, and Shinji together.
