Ultrasound of Anal Sex or Dildo Play

Hello out there.

I am keen on deep anal play and also stretching and after a medical exam it’s occurred to me to ask: Does anyone have experience of deep anal play being filmed as ultrasound was being used?

Real life images of these big penetrations into our guts to see where the toys, fists, penises etc are going?

I know there are some Manga/fantasy images along these lines, but do any of you in the community have experience of medfet doms/masters/mistresses who’ve done and published this?

I thought, because of the radiation, there’ll be little to nothing in X-ray on film, and proper modern scanners are hugely expensive and not many profs would get a proposal on deep anal play through a research hospital’s funding board… so I thought ultrasound might offer some fun insight into what’s going on inside us as we play.

So, dear swarm, what do you know? What’s out there? Anyone with access to the gear want to make something for us kinky funsters?

Might be erotic as well as illuminating, too.
