Well, I do request this one alot but only Pudzuz has actually managed to completely construct and execute it well. But, I would like to see what you can do aswell since you looking for ideas.

-Jax performs MKX Fatality on Mileena where he crushes in her arms snaps the top part of her head open, exposing the throat/teeth etc, then proceeds to throat fuck and cum in her throat {pulls out to show cum (cum starts dripping out before then)} then rips remaining body in half tit fucks upper portion (cums on tits), fucks both vaginally and anally the bottomportion of the body cums* {cum shoot out intestine part of bottom half (some intestines fall out too)} .

*As a bonus scene you could have jax rip off her head and skull fuck her {fucks mouth hole cum seeps through head (some out eyes/nose) , but inparticular seeps out neck. And one where he goes through the neck hole and out the mouth hole, but this time when he cums he gives the head a "volcano" facial and when hes done with the head he uses the body (throat) and cums there too.

Trying not to give too many ideas away trying to preserve for pudzuz but that one is free for all and has been on my list for a long time. Longer than black Darth Vador skull fucking Sheva;)
