Your favorite moment from 3D animation: passion, pain, pleasure?

I remember the scene where the heroine is held in suspension - literally and emotionally. In 3D it's so clearly conveyed: every drop of sweat, every breath and spasm of pleasure-pain..... it's like you can feel it on your own. There was a moment when she resists at first, but then... her whole face changes - suffering turns into fierce desire, and she herself asks to continue. That transition is mind blowing. I wonder why it's moments like that, where inner boundaries break down, that cling so strongly? Is it about power? Or is it about liberation?

I came across a short animation on https://18comix.org - a half-cyborg girl in a neon leather suit gets trapped inside a biomechanical ship. What happens next is pure trance: tentacles penetrating the suit, you can feel her withering in pain or suffocating in orgasms that seem to never end. I'm stuck. For a long time. Then I found a comic book about that scene, and the details are even hotter - it describes how the AI starts to control her sensations, intensifying each touch. I went back there, because the usual porn didn't appeal anymore - I wanted something foreign, wild, oblivious. And yes... I stayed. Because it's a fantasy that resonates with something that's hard to even articulate.

For me, the best moment is when a character is tense at first, all tight, like they're struggling... and then they just snap - the body, the face, the sounds - everything changes. I can't forget one such scene with an elf and a huge creature, where the tension built up for about three minutes, and then she just moaned like the world had ended. That's the kind of footage I put on repeat. Not for the act itself, but for the way it's built up - escalating, sensual, almost cinematic.
