Well, for me I guess it depends. Usually when I think of them they're more in line with a lot of Fenris49's works, where the lips may be far larger than expected, probably ranging from very moist to exceptionally wet. And, for some strange reason as it affixes itself to my expectations, there's just a sense of immense power associated with it, that it's coupled with strong, potentially overpowering tendencies.

And, in just off the top of my head, such things would probably work out well for most vanilla scenarios alone, along with the potential for hypers in many forms (be they physical like hyper cocks or in terms of hyper pregnancies and very full figures), and just plain messy lovemaking at its finest! :3

I definitely agree with all of this :3

I like them with very fat, broad labia- both majora and minora -and very wet. A super-deep vagina is expected, too, and a lot more control over internal muscles: enough to grab and pull things in or push them out with little effort. The "hanging out from the body" type is lovely, but i really prefer it when the character (whatever their gender) has extra-broad hips to make room for all that pussy- a style i see more of in Japanese art (artists like Nezumi, Himajin, or Ｈ・Ｈiroma) or Fenris49's stuff.

I really love the idea of going down on someone with such a pussy, especially being able to push myself into them... or of having one myself, and being on the receiving end (or using it to dominate and hold partners inside me). Plus, it plays well into my "massive insertion" fantasies pretty well :3

I agree with your entire first part, particularly with your shoutouts to Nezumi and all! and the second part...equally agreed. Receiving with one could be unimaginably fun, given the sensations and the unimaginable depth. Further, to pull someone in for a bit of fun would be quite exceptional as well, too. So many fascinating options! ^ ^
