There's a few in there, actually. Aside from the Undyne (undertale) one where it was just one of several positions, they are mostly short loops from the first or second threads.
There's one with Elizabeth (Bioshock, several different models of her). Another with Silent Hill's Pyramid Head eye-fucking a Nurse. The Shygirl one that was inspired by PPPPU has an eye-fuck as one of the poses, too.
