what other games did you play that has eldritch horror porn?
superhuman. doesn't get quite chuthulu levels of eldritch, but kinda close. definitely more on the 'horror' side of things.
there's also, iirc 'in the mountain of friendship' or something, knockoff of that steven king book title, where you actually are sort of an eldritch horror, but you just make people horny, over 'madness'.
i can't recall the name, but there was a game where you're basically a tentacle dimension able to 'breach' reality and grab girls to violate, i think there was more than one, or more than one 'setting' within the same game, but one of them was like a HS locker, might've been called something like 'tentacle locker'.
there's a html game called 'artifact' that sort of feels close, a little more on the 'madness' side of things than some more body horror, or just an excuse for noods, like the other two.
not my body, kinda/kinda not? i guess, it is a little bit more mystery/horror ish, but if you think of it as more 'weird demons' bullshit rather than weird eldritch shit, might not count as much to you. falls closer to eldritch to me, but, whatever.
pixel town might be kinda close to that. it does feel more demon-y, given the other character is an exorcist or some shit, but it's a lot of mental corruption and mutant tentacle bullshit, rather than like, a separate species, physical or spiritual, like most other 'demon' stuff. i do want to specify that, there'd be way more options if we counted gooey demon potential, but as a venn diagram, this feels like it has some decent overlap with eldritch bullshit, rather than just, 'magic'.
maybe feeling like i'm still stretching it, magical girl celesphonia. maybe a bit more 'biotech' than just demons/eldritch overlap, and it's more on the enemy gooey origins rahter than a story focus of horror, but, maybe 'close enough'. also less horror-y, just more standard 'rapey bad guys with a gimmick'.
there's some similar ish games that might have some eldritch corruption potential, i think, but honestl it might be even iffier, like taffy tales (like half the people in town suddenly have a lustful other personality, though no magic/demons/tentacles afaik), and ambrosia, maybe - you're a priestess who basically can swap to a sex god
there's a male to female transforming ish game called 'ep backrooms' that is less eldritch horror, but some weird sort of scp timeloop curse, but with sex.
i think coc's corruption stuff was a little eldritch, but it's also got demons, so, maybe not.

uh, *cough*, if anyone else has some others, i'd kinda be interested.
