Hardcore vore doe never fails to crank me up.
By hardcore you mean the weird kind of vore or the downright creepy one?
As for chakats...
The universe they come from has a bunch of other weird races... like foxtaurs (for some reason there are both plain anthropomorphic foxes and taur foxes).
What are foxtaurs?
A race with a 10 to 1 female to male ratio and a notable Foxtaur (Garek if i remember his name right) was gang raped by a pack of females before Goldfur (The authors self insert) saved him from his own people and married the poor sot... and the poor guy learned that his new mate has both female and male bits a bit too late.
There is also a race of herms that got progressively stupider the older (up to a point they become drooling sex obsessed idiots) they got... with the only way of slowing that proces is getting yourself pregnant and... well you can guess how that goes.
Foxes (anthros not taurs) have sex drive hormones in their blood instead of hemoglobin (not literally but close) and survived a nuclear war because they bred so fast.
Literally every race has something "wrong" with them when it comes to sex in that universe... there is even one human "cursed" by some fertility god that made him able to impregnate races that are completely incompatible so he did the logical thing and started sleeping with EVERYTHING making him the Shepard before Mass Effect was even conceived.
There is just so much shit to talk about every time someone mentions chakats...
Truth is... it's not just chakats. It's the entire universe made up around them.
