To the OP:

Seeing as you like having characters or monsters literally "mindfuck" ladies, I have an idea for you, but I don't know how willing you would be to do it. You seem to do things on your own accord which is all great and dandy; nothing wrong with that. Not sure how often you take ideas and make them into animations seeing as you get requests and ideas a ton in this thread already. I guess I'll just pitch this one and if you don't wish to do it or don't feel like it would be in your style, then that's fine. I've had this idea for a while and to see it animated would be pretty cool. I'll be as detailed as possible to paint a better picture on how it would fold out.

In Resident Evil 6, there is this monster called "Rasklapanje". It's a bio-organic weapon that literally kills to reproduce into more of its kind and does so quite quickly. Here is the death animation in full from two different camera angles:

Notice how the Rasklapanje leaves a major gaping hole in the females face. Big enough for the Rasklapanje to walk over and facefuck her corpse with its dick (not the parasite from the mouth, mind you, but a dick you could just paste onto the lower torso of it in SFM). I don't know if it is possible to recreate that hole texture on face its been drilled in from the parasite. I believe there is a model for the Rasklapanje in SFM, but I don't know where it is exactly. I have seen a few SFM animations with it used. You can use whoever you want as the victim, but I don't think there are extremely busty full nude versions of Helena Harper, Sherry Birkin, or Ada Wong out there for SFM. I know there is one of Sheva Alomar. She's from Resident Evil 5 which is fine, but I thought it'd be for fitting to have it relate to Resident Evil 6. But yeah, that's the general idea; recreate and add an extension of that death animation.

As far as how I imagined it would play out, it would go like this: Character is topless pinned down by the Rasklapanje struggling. Rasklapanje does the face drilling with the character convulsing with her breasts bouncing and jiggling. After the face drilling from the parasite, instead the Rasklapanje undresses the character and fucks her on her back (vaginal or anal). Rasklapanje cums inside and then moves towards the characters face. The Rasklapanje facefucks the character. Cums inside the face. Then the Rasklapanje walks away with the characters body creamed from both holes. After a while, the body starts to convulse really violently with arms, legs, and her breasts flopping about and then the birth of the baby Rasklapanje pops out from her chest like in the video.

It might sound like a lot to do and it probably is a heavy endeavor of a project to take on. To which I understand if you don't wish to take on this idea. It's perfectly fine. Just wanted to get this idea out there regardless. You don't even have to do it in the way described above. You're free to just take the concept itself and do it in your own style however you want with unrelated and different characters even. Your choice, your rules.

This death animation from Resident Evil 6 is one of my favorites for many reasons: the nude mods used add to the rapey factor of it, the way the character sounds when getting their faces drilled, the hole left in the face with the blood spurting out, the way the body spasms during the birth. To see it done in an SFM style with the freedom to change how it would normally go always sounded like a pipe dream to me. I do like your animations greatly and I think you're the animator who could get this done as it seems to suit your tastes well enough. Sorry for typing up so much as I know it's a bit of a read. If you don't wish to do this, then that's fine as I look forward to your other projects in the future. :)
