That's what the portals are for.

That's the thing, you can't fuck yourself like that unless the portals themselves move. If you move the hips forward to push in the penis the ass will simultaneously move away.

You're right but how to move it, it's better to wait for the portal to be there first

It's better to perform auto-oral using portals. This way, you can move both your head and/or hips without them moving away from each other.

Damn. How can I cum to this if the portal physics are inaccurate?

My take is that she positions the portals close enough where she does not have to worry about distance, but instead loseness as she has to push her dick in from the side. And that's how her "portal addiction" started. But this image is slightly different, she positioned the portals too far apart and all she can do is hopelessly thrust without entering. She is so horny that the idea of getting off like this completely sends her over the edge.
