I found some video footage of this game:

And if anyone could tell me it's name or link it to me, that would be nice.

I would post the link to the video, but it is on pornhub...

I only recognize the cobra - qhala if I'm not mistaken

Yes, I am pretty sure it is that character, as someone else stated this on the pornhub comment section. I also looked on this site for it, but I could not find anything.

Also someone else stated that it could be a S.D.T. (Super Deepthroat) mod.

looks like heavily modded super deepthroat

Well, I cannot link you any game, as there isn't any. I do know that super duber puppet animation though because I remember trying to explain this artist how to properly convert videos into formats that can be shared online. Sadly they still used flash with furaffinity limitations, so quality is as bad as it is with that video you linked.
