To me it's more about imagining oneself in the place of the pit. Having a hundred hands and arms to bind and draw her in to my warm fleshy pleasure prison, making her my sex puppet for as long as I like. Getting to caress her all over at once. Restraining all four limbs in whatever way I like. Encircling her breasts. Maybe sucking a quick snack out of her nipples like >>11286472 mentioned. Railing whichever holes seem hungriest. Doing it all at the same time.
There's an element of "fucking the whole woman" that doesn't always show up in other forms of tentacle media that I like about it. I especially like the rare combination with hypno (pic related) where I fuck her brain too.
The few times I've ever felt physical attraction to a woman in person, the best way I could describe the feeling I got was that I really just wanted to coil my whole body around hers from head to toe, and that's difficult to depict in more realistic porn, I guess.
